1987 Case Study: Flavorite Lab Switches to Continuous System
Flavorite Lab, Inc, a manufacturer of seasonings and processor of natural spices was looking for a modern, efficient system to replace the equipment they had been using for cleaning spices. The company was not happy with the way their existing system handled safety products, such as sage. And they also wanted to convert from a batch system to a continuous cleaning and grinding process.
Multi-Purpose System Design
After some initial product testing at the Kice lab, Kice started designing a multi-purpose pneumatic spice cleaning system. Although the system was initially designed for cleaning sage, it also had to have the capabilities for handling other spices such as red peppers, oregano, black pepper, coriander, and anise.
Kice developed a system which would pneumatically lift the products from feed hoppers and convey them to dual aspirators for cleaning. As the spice went through the first aspirator, it would receive a light cleaning. At this stage, dust and any light foreign materials were removed. The product was then relifted and went through the second aspirator, where heavy suction lifted good product through a cyclone and over to its final destination (in this case, a mill for chopping the cleaned sage). During the second aspiration cycle, the heavier foreign material, such as sticks and stones, was dropped into a receiver.
After the product was removed from the conveying air, the air went through a filter and was recycled back to the process plant. The same principle was used for cleaning more delicate products such as red pepper. However, these materials only went through the first aspirator and then were dropped out into a bin. The dust and debris were removed without damaging the product by further handling.
Equipment Lab-Tested Before Shipment
The modular system was preassembled, pre-wired, and tested with Flavorite’s products in the Kice lab to ensure any issues were addressed before delivery onsite.
The unit was then knocked down in major sections for shipment. The Kice system components included airlocks under each of the three cyclones and one under the filter, a high static fan and filter suction fan.
A reverse air pump for cleaning filter bags used a 7 ½ H.P. motor. Spreaders were positioned ahead of each aspirator to spread the material so it would slide evenly across the aspirator. There was also a 1 ½ H.P. motor on the sage dump hopper.
