動物副産物の空気分級
Document Type and Number:
Japanese Patent JP4097293
Kind Code:
B2
Abstract:
The utilization of an air cyclone classifying method to effectively separate out a low ash fraction, containing less than 11% by weight of non-protein material, from rendered animal meal. A yield of low material greater than 50% by weight is recovered as usable canine and feline food. The method involves the creation in a first cyclone separator of a double vortex air cyclone having a descending external air vortex and a rising internal air spire; wherein an upper chamber therein is equipped with a rotary particle rejector. The rendered animal meal infeed is fed into the rising air spire which entrains and carries the low ash fraction through the rotary particle rejector, to a second cyclone air cleaning device; wherein the low ash material is recovered from the entraining air. The larger and denser high ash particles are recovered from the first cyclone separator.
