Good Vibrations

In an extremely demanding industry, Farbest Brands discovered that using compact vibratory screeners for scalping and sizing materials optimized product throughput and equipment uptime, while meeting highest quality sanitation requirements. For almost 50 years, Farbest Brands has been a food ingredient supplier to many of the large and small manufacturers for everything from proteins and vitamins to sweeteners, preservatives and specialty products. The company’s custom manufacturing services include specialized dry blending, particle sizing and sifting, and sophisticated liquid blending capabilities. Farbest even has a complete food development laboratory that enables customers to fine-tune their formulas and react to changes in market trends.

To meet the demands of its customers, Farbest imports ingredients from all over the world by the truckload for distribution or manufactures in its own plant in Columbus, Ohio. The ingredients it produces must not only be of the highest quality, but also designed to mix, blend or liquefy according to specifications that meet a customer’s own production and quality standards. At the same time ingredient producers like Farbest must also meet very high quality, hygiene and safety standards including HACCP, as well as competitive pressures such as critical JIT delivery schedules.

This means it must be both flexible and efficient, which requires the right equipment to minimize downtime and get the needed throughput. For Farbest, this meant finding the right fine mesh separators to efficiently screen food powders and liquid slurries to ensure final product quality.

“When it comes to flat screening, we need to move large volumes of material through rooms with limited space,” explains Dennis Cowles, Farbest’s maintenance manager. “It is important to have vibrating screeners that are not too large, not easily damaged and easy to clean.”

While those requirements may seem simple enough, they are not always easy to achieve. Some equipment designs are more prone to occasional breakdowns such as screen tearing during high-volume operations. Various designs have components that can vibrate loose and enter the product stream below the mesh screen. In addition, cleaning these screens to meet stringent hygiene requirements can often be tedious and time consuming if you don’t find the right equipment.

To avoid these problems, Farbest Brands uses a high-capacity, 36-inch vibratory Compact Screener from Russell Finex, Pineville, N.C. Although Farbest uses other screening and separation equipment, Cowles says he was looking for a system that fit into an area with limited headroom when he noticed the Russell Compact Screener in some trade journals.

All Farbest Brands processes are HACCP (Hazard Analysis and Critical Control Point) controlled. Russell Finex has extensive experience in working with customers to determine the appropriate use of screening and filtering equipment to meet these requirements.

For more than 70 years, Russell Finex has been manufacturing and supplying separators, screeners and filters to ensure that powders and liquids are free from contamination, improve product quality, enhance productivity and safeguard the health of workers. Their unique, compact vibratory screeners are a breakthrough improvement over conventional screeners whenever headroom or room sizes are issues.

Screening is a primary operation for ingredient manufacturers like Farbest. “We use a certain size of screen to prevent agglomeration of product, so that it mixes well with other products, and doesn’t ball up,” says Cowles. “We often screen material before is goes into a mixer, for example. We don’t want any particles that are greater than a certain size so that we’re sure it will work for our customers when they make the end product.”

Cowles felt that the compact size of these screeners would be very beneficial to his operation. “We have limited space in our production rooms, and they are often filled to capacity by stacks of material in bags. The compact screening equipment, which is used for scalping (removal of larger contaminants), enables us to use more of the room for material, and eliminates the need to have a costly conveyor to transport material from one room to another,” he says.
