ADVANTAGES
- urease activity in soybeans is reduced to 0.05 … 0.2 pH
- the trypsin inhibitor content is reduced to 2 … 4.5 mg / g
- production of raw materials for the extraction of oil, for the production of soybean meal
- production of poultry feed component – saturated with protein and fats
- provides animal feed of a high quality
- saves over 40 % of grain for animal feeding
- saves over 30 % of electricity while processing the feedstock prior to mechanical oil extraction
SEQUENCE OF OPERATION
The first step is the pretreatment of raw material. It must have the proper moisture and must be cleaned from metal residues and any waste.
Raw material is fed from hopper intoa screw barrel. Magnet catcher is installed within a hopper so it can catch any metal residues you’ve missed. Inside the barrel there is a screw that conveys the raw material forward to outlet die.
Extrusion is a process of thermal treatment, sterilization, dehydration, texturing and granulating of the final product.
The product goes through the barrel while the heat is progressively increased.
During thisprocess most potentially harmful bacteriaand viruses are killed, inhibitor trypsin level in extruded soy is reduced.
The final product is shaped by forcing out through the die.
