Abstract From the Canadian patent

A dynamic dehydrator system for processing a wide range of materials such as milk, eggs, animal and poultry by-products automatically and continuously operates from temperature sensors controlling the rate of positive feed speed of the by-products along a feed passageway through a set of heated cylindrical containers. The system is hermetically sealed to prevent pollution and removes escaping vapors and odor. Good power input efficiency is attained by heat-exchange design of the heating cylinders and for processing meat by-products by temperature controlled feedback of heated grease output to mix with the input raw materials.
