Seal Tite Diverter Provides Solution for Pet Food Company

The client had a need to replace a flap type diverter valve which had been in service for a considerable period of time. The existing diverter valve had reached the end of its service life and was difficult to clean and maintain due to its design. The new diverter design had to cope with a variety of sticky and abrasive feed material, with easy access for cleaning and maintainability, whilst being fast acting to allow reject material from a metal detector to be diverted out of the production stream.

Roller Gate with Fail Safe Tank to Handle Granulated Sugar

This Vortex Roller Gate will be used to handle granulated sugar. The valve features a fail-safe closed assembly for operation of valve one-time on loss of air supply. Upon electrical failure and a loss of plant air, the single solenoid valve will shift, allowing the compressed air to flow from the reserved tank, through the solenoid valve to the double acting air cylinder closing the gate.

Long Fiber Reinforced Thermoplastics

Long Fiber Reinforced Thermoplastics are a recent development in newer technologies where PP or thermoplastic material is directly compounded with long glass fibers (rovings) and then molded in one operation. Long Fiber Thermo-plastic technologies are the buzz of the auto industry in Europe and the US and are one of the most important trends in the plastics industry today.

Powdered Drink Mix Blending and Packaging System

A customer was building a new facility that had a room dedicated for use in their powder blending process. They contacted NBE to help develop a solution that will meet their process needs and fit inside the space they have available. The system needed to handle raw ingredients from supersacks as well as small bags. Recipes were based on even numbers of the raw material packages. All of the material must be discharged, screened to prevent any contaminants, and discharged into a horizontal ribbon blender. Attention must be paid to ergonomic handling of the materials, including the scissor lift for bag positioning, along with disposal of the empty packaging from the upper levels of the system. The finished blends were packaged in super sacks that will ultimately be used to supply their packaging line. NBE designed and manufactured a custom three-level platform to support all of the equipment in the available space. NBE coordinated with the customer’s dust collection vendor once the system was assembled in our facility. The vendor came and installed the vent lines under the platform structure in our facility. The customer visited for a final inspection of the completed system assembly prior to shipment and was very pleased with the finished product.

Conveying Grape Waste at Winery with Screw Conveyor

Stainless steel construction was used to prevent corrosion, and continuous welds were provided to prevent debris from building up between the pipe and flight connection. Flush out ports were added to the side of the troughs to allow residual grape juice and cleaning fluids to drain freely. Hip roof covers were used on the conveyor section located outside the building to prevent rain from collecting on the housing. To work within the required space constraints, a shafted horizontal conveyor was custom designed to feed directly into an inclined shaftless conveyor in place of using a CEMA standard inlet and discharge connection. The shaftless conveyor utilized a dual spiral shaftless screw to ensure that the grape pomace conveyed easily up the incline.

Distillery Goes Green with Centrifugal Separation of Stillage

Grain solids unable to pass through screen apertures are propelled in a helical pattern through the screen cylinder until being discharged through its open end, into a chute that funnels the dewatered solids into a plastic tote on a pallet below. When a tote is full with about 2,500 lb (1,136 kg) of the damp grain, a pallet truck replaces it with an empty tote. The full totes are stored in a holding area to be picked-up by a farmer.

Metering and Conveying Spent Brewer’s Grain Using Screw Conveyor

The conveying system previously in place, progressive cavity pumps, proved to be a significant and consistent maintenance problem resulting in brewing downtime. KWS replaced the problematic pumps with four inclined screw feeders to meter the spent grain out of the collection bins below the filter presses. These four inclined screw feeders meter the spent grain to a single collection screw conveyor that transports the grain to another system of screw conveyors that conveys the grain to its final destination.
