Pilot Testing

The pilot plant equipment installed in the work areas is of the smallest feasible design to yield indicative results suitable for scale up to commercial size equipment. All necessary allied accessory items are available. Auxiliary items such as condensers, stainless steel kettles, pumps, product flakers, etc., are maintained within the laboratory at all times.

The feasibility test is the first step in determining the right equipment to be used in the design process. If data does not already exist in our extensive product files, the feasibility of processing a material can be determined with quantities as small as one gallon of liquid or ten pounds of solid material. Feasibility tests are conducted at no charge to the customer. If a process appears feasible, pilot testing can be conducted to obtain heat transfer and other engineering data needed for the design process. The cost of process equipment is quoted to customers with a process guarantee upon successful completion of pilot testing.
