rugged springs that allow it to vibrate freely while minimising power consumption and preventing transmission of vibration to the floor. One imbalanced-weight gyratory motor creates multi-plane inertial vibration to the screen deck, controlling the flow path of material on the screen surface and maximising the rate at which material passes through the screen. The on-size material exits through a discharge spout located at the screen’s periphery. Particles smaller than the screen apertures pass through and exit through a lower discharge spout that feeds the packaging machinery. The screener’s 76.2 cm diameter screens are interchangeable, and range from 20 mesh (864 µm) to 60 mesh (234 µm). “We’re currently testing an application that would require use of a 200 mesh (74 µm) screen, and Kason is helping us explore several techniques for prevention of screen blinding,” he says.
“Oversize materials removed by the screener usually amount to a few kilograms, accounting for a relatively insignificant percentage of the total batch weight. “This is evidence of our skill and expertise in optimising the spray drying process,” says Mr. Kimmick.
On-size material is packaged in a variety of
containers ranging from 11.3 kg to 90.7 kg boxes, bags or fiberboard drums, or bulk bags weighing as much as 907 kg.
PROCESSES MEET SANITARY STANDARDS
Because many of the materials processed by Summit Custom Spray Drying are food or pharmaceutical ingredients, the facility operates under Good Manufacturing Practices (GMPs), is registered with FDA (U.S. Food and Drug Administration) and USDA (U.S. Dept. of Agriculture), and is qualified to process to Kosher standards.
A campaign can be as short as one shift or as long as one week. Between campaigns, operators clean all the spray drying equipment, including the screeners, with hot water, followed by a cleaning agent, and then a sanitising agent. As a result, the screeners routinely pass Hazard Analysis & Critical Control Points (HACCP) inspection. Mr. Kimmick anticipates adding more spray
dryers and screeners as demand for its services grows. “We currently serve dozens of customers and anticipate a customer base of over a hundred,” he says. n For more information please contact Kason on tel: 01782-597540 or visit:
