The right combination of the two elements ensures that a product is conveyed by pushing it from point A to point B.

To optimize this process, Van Beek has developed seven finish levels with two options: a rolled screw and a screw composed of separate screw blades. But what is actually the most ideal combination and why is a high gloss polished screw not necessarily suitable for the conveyance of all products?

Before we go into the different finish levels let us first briefly explain the difference between a rolled screw and a screw composed of separate screw blades. While the material type and mechanical quality of the two screws are similar, the difference lies in particular in the finish. For example, the surface of a rolled screw is rougher and it can be produced more quickly than a screw composed of separate screw blades. In addition, rolled screws have a tapered blade thickness and a screw composed of blades has a constant thickness. With a rolling process that Van Beek has developed itself a very dimensionally stable product is produced because the screw blade is rolled directly around the inner tube, hence the name ‘rolled’ screw. During this process, the starting material is forced between two conical rollers round the tube (rolling), as a result, the blade on the inside is thicker than the blade on the outside. An innovative solution where the construction itself has no disadvantages.

Smoother is not always better

Where the production of rolled screws can be seen as something purely mechanical, the production of screws composed of blades consists of 90 percent manual work. Because the screw blades for this finish are cut from sheet material and then pressed by a hydraulic press to the right pitch, after fixing to the screw tube this gives a smooth surface. In the case of finish 7, this is a high gloss polished screw, that conveys products in a streamlined way. This high quality immediately gives rise to misconceptions. Other than you might think, this shiny surface is not necessarily suitable for conveying all products. “Customers often think ‘the smoother the screw, the better’, but the opposite is true. The smooth surface may in fact mean that a product sticks to the screw. A slightly rougher screw is in some cases better for preventing sticking”, says Eric de Jong, Manager of Operations at Van Beek.

Conveyor performance

The secret lies in the right combination of the screw and the body, which both help to convey the product. The screw pushes the product forwards, but the amount of movement is also based on the type of body. In short: conveyance of the product is the result of the combination of movement and friction. In addition, a higher-finish level can be achieved with screws composed of blades, when these are used for products that do not involve sticking or fouling. “The wrong choice definitely affects the conveyor performance”, says De Jong.

Every industry has its own screw

It is then big chemical groups like DSM and Shell and pharmaceutical companies that use our finish 7. The food sector on the other hand often chooses finish 5 or 6, because, in addition to a flexible conveyance process, they also have high regard for hygiene due to the finely sanded, smooth screws. This gives bacteria as little chance as possible of nestling in chinks and holes.

The story is very different for example for the rolled, rough, completely unsanded finishes 1 and 2 that are therefore particularly suitable for example for the recycling industry for chopped plastic flakes or conveying rubber granules. Finishes 3 and 4 are the finish levels mostly chosen as part of a complete Van Beek screw conveyor system. These screws are machined during the production process using respectively glass bead blasting and wet blasting, which makes the screw surface ideal for conveying semi-finished products.

Further development

Van Beek would not be Van Beek if we were not continuously innovating. This certainly applies to the production of screws composed of blades, an intensive process that still consists of 90 percent manual work. De Jong comments: “At present, we are working on the development of a machine for sanding and polishing these screws, a labor-intensive job that at present is largely done by manual work”.

C&M Seeds’ Expansion Boosted By Self-cleaning Tubular Chain Conveyor From Luxme-顺心彩票 http://www.shandrenko.com/cm-seeds-expansion-boosted-by-self-cleaning-tubular-chain-conveyor-from-luxme/ Fri, 28 Aug 2020 12:37:44 +0000 http://www.shandrenko.com/?p=112287 In the last 18 months, Luxme International has installed a Tubular Chain Conveyor with automatic Stay Clean technology to meet the expansion of C&M Seeds’ primary processing and storage facility in Palmerston, Ontario.

The post C&M Seeds’ Expansion Boosted By Self-cleaning Tubular Chain Conveyor From Luxme appeared first on 顺心彩票.

The North American seeds market is expected to grow annually at a CAGR of 6.9% between 2020-2025, with Canada contributing significantly to the continent’s 35% of the global market share. Sitting firmly at the center of the nation’s first link in the agri-food chain is C&M Seeds, a small but significant supplier of red wheat genetics and marketer of soybeans, barley, oats, and mixed grains.

When the company undertook a 30% storage capacity expansion project to its primary facility, a sealed, top-of-silo handling conveyor was required to meet growing business demand. C&M Seeds outlined dust control, durability, and easy maintenance as key criteria for the transportation system at its Ontario seed processing facility. The capability to withstand harsh environments and eliminate the risk of cross-contamination between seed batches were most important.

After receiving proposals from a number of machinery developers, the company was won over by the performance, reliability, and design benefits of Luxme’s automated Tubular Chain Conveyor with Stay Clean technology. “Our project team, operators, and management felt this was the best option to achieve our need for very high-quality operations,” said Rob McLaughlin, Sales & Marketing Manager, C&M Seeds.

Removing the risk of cross-contamination

As a supplier to over 200 seed retailers and countless farmers across eastern Canada and beyond, C&M Seeds needed to improve the process of transferring finished batches to one of eight silos while maintaining the highest standards of quality. As a Certified Seed producer, the firm has earned its respected reputation and accreditation by following a rigid set of quality control standards set out by Canada’s Plant Breeders’ Rights (PBR) Act. In order to eliminate the risk of cross-contamination, these standards have to be maintained when transporting the company’s seed species – including winter wheat, spring wheat, and soybean – to the silo for storage. The challenge was achieving this with one machine.

Explaining the issue, Rob says: “Our business depends on supplying 100% pure seed stock; just one kernel can contaminate a batch, which we work very hard to avoid. Any contaminating variety of seed will create serious complaints and lead to significant losses for the retailer.”

Luxme presented C&M Seeds with a solution: the food-grade Tubular Chain Conveyor with automatic Stay Clean technology. The system ensures a clean operation without cross-contamination between seed batches thanks to its self-cleaning technology. A chain disc tipper, disc cleaning brush station, and wiper discs cleanout and purge the machine of any product, before operators inspect the interior for any visible residue after each batch.

Elaborating on the benefits of the Stay Clean technology, which includes gentle product handling to convey seed stock without breakage or product degradation, Rob states: “As the machine runs, it cleans itself and purges any random seeds. These are cleaned off the equipment and delivered back to the designated silo they were initially intended for. Also, we have noticed that there is no additional damage to the seed after the cleaning process – a definite plus compared to other handling lines, such as augers and individual bin downspout systems.”

The self-cleaning technology has reduced maintenance costs and contributed to higher ROI. Since installation in June 2019, Rob reports the company has saved two hours of washdown labor time between each batch, adding: “We have had to service the system much less frequently than other equipment and technology we have used in the past.”

Built to last through rain or shine

In addition to eliminating the potential for cross-contamination, protecting the product from external influences was also crucial for C&M Seeds. Since the conveyor is required to operate over 78-ft high silos throughout the four Canadian seasons, consistent performance with minimal maintenance were important factors due to the associated cost and difficulty of servicing equipment at high elevation.

Discussing the project, Rick Leroux, Vice President and General Manager at Luxme, says: “Our conveyor needed to run clean without carry-over and operate reliably outdoors with minimal service. It had to be insensitive to weather conditions and deliver worry-free operation 12 months a year.”

Rather than commissioning an off-the-shelf unit, the Luxme team worked collaboratively with C&M Seeds to engineer a unique transportation solution. Designed for high reliability, the conveyor runs with minimal power consumption at 7.5 HP with full load start and stop capabilities. It operates quietly as it transfers the product to any one of six electrically operated, high-efficiency Luxme rotary valves, which direct segregated and cleaned seed batches to any of the eight new storage silos. 

The Tubular Chain Conveyor now performs at capacity with a throughput of 21,000 bushels-per-hour, receiving material from a bucket elevator that transfers the seed vertically to the top of the silos. Using a VFD drive, operatives can increase or decrease speed as necessary, allowing the conveyor to match the speed of the cleaner at the final stage before storage.

A heavy-duty framework and durable components provide protection against the harsh, changeable environment of its location. These components include a case-hardened chain; high efficiency electrically operated rotary valves; continuous cleaning and purging of dust and moisture with a combination of wiper discs, disc tipper, and rotating brush assembly; and a continuous chain tensioning device. An enclosed design eliminates any dust generation and protects the seed from moisture, water, and outside contaminants while moving through the pipe.

Taking safety to new heights

Another advantage of Luxme’s Tubular Chain Conveyor is improved health and safety. Beyond low maintenance and a highly efficient and effective process flow, it was imperative for the wellbeing of C&M Seeds’ workforce to remove the need for regular high-risk, outdoor servicing. The automatic Stay Clean technology, robust design, and a fixed drive with self-regulating continuous chain tension assembly mean a safer operation for staff members, reports Rob: “The conveying solution from Luxme has allowed us to significantly reduce our hazardous, elevated work practices; much to the benefit of our employees.”

Commenting on the installation, he concludes: “We have noticed the operation is worry-free. All we have to do is set the speed at the start of the batch and just let it run. The C&M Seeds team is extremely satisfied with the innovation and support provided by Luxme for this important step in our expansion process; we will definitely look for other areas in our business where a Luxme unit will fit.”

Reconsidering Composite Vents for Explosion Protection-顺心彩票 http://www.shandrenko.com/reconsidering-composite-vents-for-explosion-protection/ Fri, 28 Aug 2020 08:37:34 +0000 http://www.shandrenko.com/?p=112243 Wherever combustible dust can accumulate, the risk of an explosive event is present.

The post Reconsidering Composite Vents for Explosion Protection appeared first on 顺心彩票.

This poses a significant risk to industries such as Food, Grain, and Feed. In response to this hazard, in 1945 the National Fire Protection Association (NFPA) initiated a tentative standard, NFPA 68 titled ‘Standard on Explosion Protection by Deflagration Venting’, updated in 2007 to a Standard, and is currently in its 2018 revision which provides specific direction to mitigate the risk through the use of venting. Today explosion venting is the most commonly used method of mitigating the pressure effects of a deflagration.

Designed to open rapidly at a predetermined burst pressure, explosion vents allow the combustion process to escape to the atmosphere while limiting the pressure generated inside the process equipment to calculated safe limits.

This type of vent is installed on dust collections, conveyors, bucket elevators, dryers/ovens, bins, and silos. 

For more than 50 years, traditional composite vents comprised of plastic film sandwiched between two stainless steel sheets have been utilized for this purpose.  However, this design approach has largely fallen out of favor in all but a few niche applications due to significant disadvantages, including the risk that dust and process debris can accumulate such that it affects the speed and reliability of the vent opening.

“Over time there can be an evolving risk with composite vents that leakage will occur, or that dust or process materials will accumulate within the layers and the vent will become very heavy and won’t function as it should,” says Geof Brazier, president of BS&B Pressure Safety Management, a manufacturer of a broad range of dust explosion prevention and protection technologies.

This has some facility personnel taking a closer look at more advanced single sheet vent alternatives that weigh less and include design features that make them more durable, even in the presence of light vacuum conditions or vibration.  These modern options also reduce installation costs while increasing service longevity.

Vent Inspection

NFPA 68-2018 Standard on Explosion Protection by Deflagration Venting establishes requirements for the design, location, installation, maintenance, and use of devices and systems that vent the combustion gases and pressures resulting from a deflagration within an enclosure so that structural and mechanical damage is minimized.

Within the NFPA 68 Standard is the requirement that installed explosion vents in service “shall be inspected” to ensure their integrity as they perform a critical safety function.

However, in practice, many view explosion vents as ‘set it and forget it’ safety devices, and often fail to complete periodic inspections.

According to Brazier, regular “up-close-and-personal” inspection is critical given that internal damage and material accumulation is typically not visible at a distance. 

In many cases, this set-it-and-forget-it approach is owing to a less-than-complete understanding of the risk factors associated with composite vents compared to more modern alternatives.   

Composite Vents

The composite vent design was introduced by BS&B Safety Systems for more than 50 years and marked a milestone in the achievement of low set pressure from relatively thick sheet metal.

Composite vents are typically made of a 3-part sandwich construction of plastic film seal between two sheets of metal, usually stainless steel.  The two metal sections are slotted with intermittent uncut sections that control the burst pressure and vent opening. 

The outlet side metal section controls burst pressure, while the inlet metal section protects the fragile plastic film and provides some degree of vacuum resistance. In this design, the vents “open” typically at 1 to 1.5 PSI set pressure. 

Composite vents can be either flat or domed, depending upon the application conditions, with domed vents being recommended for vacuum service.

The disadvantage of this type of construction is that it allows dust to penetrate between the inlet side sheet metal and plastic film, resulting in leakage overtime when angular dust particles puncture the seal. 

Although significant damage to explosion vents may be visible at a distance, internal damage may not be observable without close inspection.

If damaged, the vent could draw in humid air and even rainwater, particularly under light vacuum pressure.  This can potentially affect the product inside process equipment.  For dry items in storage, for example, moisture can cause clumping of material and even the agglomeration of dusty material.

“It can be a real inconvenience if the customer’s process is impacted because an explosion vent is damaged,” says Brazier.

There are additional risks associated with sandwich-style composite vents. 

Over time, pounds of debris can accumulate inside the layers, doubling and even tripling the weight.  In cold weather conditions, icing can occur as well.

“We’ve seen instances where a small 3-foot by 3-foot vent that weighs 20 pounds brand new, after years of accumulating material between its layers, now weighs 40 pounds.”

In addition to being unsanitary, particularly for food processors, the increase in mass due to the accumulation of material means that the vent will not open as fast as planned.  The result can be higher-than-expected pressure in the dust collector or other protected equipment in the event of explosion vent activation. “Without the expected relief [from venting] a dust explosion can overpressurize the equipment, causing significant damage,” says Brazier.  “Worst case, the explosion could escape through a weak point – and not the explosion vent – causing an uncontrolled release of flame, dust, and pressure where it wasn’t planned.”

Single Section Vents

As the demand for explosion protection technology grew, BS&B later developed the single section vent.  In this design, a single sheet of metal is intermittently cut about its perimeter and then gaskets are applied to cover the cut pattern. 

Eliminating the fragile plastic film seal and one sheet of metal greatly reduces the mass of an explosion vent, making it more efficient at responding to the rapid rate of pressure rise arising from a dust or gas explosion.

The superior design allows the vent to handle high vacuum operating conditions and cyclical operating pressure conditions.  It also eliminates product build-up, enabling the vents to be used in clean service applications.

Single Section Compound Domes

In 2010, BS&B improved on the single section vent design by altering the shape of the dome to a unique compound geometry.  This advance was born out of a desire to increase the vacuum resistance of the vents, without increasing the weight. 

The compound dome has curves at the corners of rectangular and square vents that deliver even greater rigidity for high vacuum or vibration applications.

The primary purpose of the domed construction, on the other hand, is to provide greater intrinsic vacuum resistance.  This is important, as storage, pneumatic conveying, and dust collection systems often operate under light vacuum conditions.  Industrial dust collectors can also utilize short pulses of compressed air to clean and extend the life of their bag or cartridge filters.

In these types of operating conditions, domed vents are more stable and resilient, increasing service life when compared to flat alternatives.

According to Brazier, the vent mass is critical when calculating vent sizing. Recent revisions of NFPA 68 include a review of vent mass for every application.  The results may mandate a larger vent area for less efficient, heavier explosion vents.

In short, this means a composite vent would require a much larger vent area to perform the same job than more efficient, lightweight, and modern alternatives.  This adds to the costs of installation.

“Everything we can do to keep vents lightweight, vacuum resistant, vibration resistant, and ultimately very stable helps us avoid increasing the vent area,” says Brazier.  “This means a more economic installation for the customer.”

Brazier adds that these factors have increasingly come into play in the past ten years, creating the very real possibility that aging explosion vents may be sized and selected without allowance for the mass or inertia adjustment factors.

The compound dome feature has also resolved another longstanding challenge involving the framing on which the vents are mounted.

In many cases, these frames are built by the end-users out of angle-iron.  Over time, the framework can bend or buckle – a common occurrence that can reduce vacuum resistance and can even cause the vent to fail.

The improved compound dome design is more tolerant of variations in the framing and less sensitive to the operating application and installation conditions.

For its flagship VSM product, the company has also included an integral frame to the vent flange to further simplify installation.

“These design features provide more control over how the vent behaves in the field and much less relevance to what happens on the user side [installation],” says Brazier.

Applications for Composite Vents

While single piece vents offer the best solution for most applications, there are some exceptions where composite vent technology provides the best performance. In particular, this is for applications that utilize combustion systems with hot exhaust gases.

The BS&B patented HTV vent has internal thermal insulation that allows for service conditions in excess of 1000 degrees Fahrenheit.

With this type of vent, insulation material isolates the plastic film and burst control metal section from extremes of service temperature. 

“By placing the insulation inside the layers of the composite vent, you can achieve very high resistance to temperature while maintaining the low set pressure explosion protection capabilities,” says Brazier.

They are used with particular success in agglomeration-free rapid drying, heterogeneous reactions with systems of different substances, extraction, sterilization and in general for vacuum, positive-pressure, thermal energy and comminuting aids.

PerMix PTPD or PTSD series Vacuum Mixers

The considerably superior heat transfer characteristics of PTP/SD Vacuum Mixing Dryers are mainly attributable to the fact that external heat applied through the contact surfaces of the mixing vessel and mixing element, supplemented by frictional heat generated during the mixing process.

When operating at the usual speed, this accounts for 30 to 35 per cent of the total heat applied. Heat transfer is not inhibited by agglomerates or layers of material adhering to the internal components of the tank. This is largely due to the comminuting units and the high-speed, edge-sweeping paddle agitators, which ensure rapid circulation of the materials at the contact faces.

PerMix PTPD or PTSD series Vacuum Mixers

This particular PTP/SD 100 unit, was specially designed to have both the paddle and the plow inner shaft (Hybrid type), for optimizing the drying process to the dried product, is a cantilever designed for ease in cleaning and shaft change, has double mech. seals with cooling systems on both main shaft and chopper shaft, is fully vacuum rated (up to 50 Mbar absolute ), built-in dust filter housing with self-cleaning ability, special (our made) semi hemispherical manually operated valve, and a specially designed discharging system with dust free operation.

Most people think of Greece for its sandy beaches, warm climate, and long summers. Although this might be largely true, Greece also has a prosperous food industry sector owing to Greece’s legacy of agriculture and food processing.

According to an analysis published by PWC in June 2018, the Greek food industry represents 29% of the country’s GDP, corresponding to a gross €15.1bn revenue per annum. According to PWC, there are some 15,700 Greek companies in that sector, with 106 off them being well established and highly competitive and extroverted.

Owing to its prominent food sector, Greece has significant know-how in the engineering, design, and construction of bulk material handling projects and equipment manufacturing. It is not surprising that major foodtech multinationals such as Buhler AG of Switzerland and others are represented here for decades.

At the same time, a number of Greek bulk handling engineering & construction firms and consultancies are based in Athens operating in Greece and abroad. Most of them have adopted an outward outlook, exporting equipment and services and securing contracts all over the region and especially in South-East Europe and the Balkans, and Middle, East, and North Africa.

Operating under the standards of the EU, these specialized firms deliver the highest level services and first-class equipment. Maintaining quality as any other European manufacturer, Greek bulk handling tech firms offer innovative products and services at substantially lower rates compared with their northern EU counterparts, partially due to the restructuring of the Greek economy in the years of the financial crisis as well as because of the reduced freight costs involved towards these neighboring regions.

The prospect of obtaining cost-efficient European services and equipment is appealing. Buying expensive products cheaply is certainly attractive, especially amid the challenges many modern businesses are facing under the adverse circumstances of our times.

VRAYKOS is a global provider of industrial solutions and equipment manufacturer based in metro Athens, Greece. Established in 1993 and ran by an innovative team of engineers, Vraykos specializes in the Engineering and Construction of complex bulk handling projects in the Food Industry, Snacks and Bakery, Coffee Industry, Flour Mills and Plastics and Chemicals.
