Environment-friendly production process of high-protein feeding meat meal

Abstract

The invention discloses an environment-friendly production process of high-protein feeding meat meal, comprising the following steps of: (1) removing impurities and cleaning leftovers generated after animal products are processed; (2) grinding and cutting so as to crush the leftovers; (3) entering into a hot spraying furnace and then carrying out three-stage heating and pressurizing, wherein the pressure is 0.5-1kg, the first-stage temperature is 100-110 DEG C, the second-stage temperature is 120-140 DEG C, and the third-stage temperature is 150-160 DEG C; recovering water steam by condensation and deodorizing and discharging non-condensable gas; and (4) entering into a squeezer to carry out solid-liquid separation, wherein solid phase: cooling, drying, crushing and sieving meat meal, then inspecting and finally packaging and putting in storage, and liquid phase: inspecting oil and then packaging and putting in storage. The invention has the advantages that: 1. by adopting a hot spraying technology, defatting and dewatering are carried out by the screw type squeezer through three-stage heating and pressurizing at the temperature of 100-160 DEG C to synchronously carry out water evaporation, fat collection and meat meal preparation, thereby not only improving the protein digestive rate of the meat meal but also increasing the dry substance content and the protein content in the meat meal; 2. the water content and the fat content are low, and the shelf life is long; 3. the palatability of the meat meal is improved, and the grazing rate of animals is increased for more than 90 percent from 50 percent; and 4. energy saving and environmental-protection discharge are realized by water steam recovery and discharged gas purification.

Description

technical field [0001] The invention relates to a production process of meat powder. Background technique [0002] my country is a large agricultural country with well-developed animal husbandry. The amount of livestock, poultry and other animals raised and slaughtered ranks among the top in the world. During the processing of livestock, poultry and other animal products, a lot of leftovers are produced, and many of these leftovers are destroyed. Abandonment has caused great waste and also polluted the environment; since the leftovers of livestock and poultry are mainly animal viscera, fat, minced meat and carcasses that are not suitable for consumption, they are rich in protein and energy, and are also very good Calcium and phosphorus sources, turning these livestock and poultry waste into meat powder can solve the problem of insufficient animal protein and fat in the feed, but the current processing method is very extensive, and the processed meat powder has low protein cont...
