Drying principle: put waste in the role of dry heat and pressure of the system of the machine and achieve the goal of the system. (don't direct contact with the hot steam system of meat resin, and cycle in a sandwich)
Principle: wet process using high pressure saturated steam, direct contact with livestock body organization, when steam is condensed in the presence of livestock resin for water, release a large amount of thermal energy, can make the melting fat and protein coagulation, at the same time by means of high temperature and high pressure, it completely kill the pathogen.
Wet mechanism is the use of wetting principle will disease animal bodies and diseased parts by using high temperature sterilization equipment. Via wet mechanism system of animal body can endure into industrial oil, also produce other residue.
