Embodiment
[0018] A method for producing animal fat for feed, comprising the following process steps:
[0019] (1) Material selection and pretreatment: Select 5000Kg of pork raw fat, wash the impurities in it, and grind it into 1-2cm minced meat by a meat cutter;
[0020] (2) Put the minced meat pretreated in step (1) into a vacuum heating pot, add 5000Kg of water, heat up to 58°C, and vacuumize, the vacuum degree is -0.03mpa;
[0021] (3) Add 1.5Kg neutral protease;
[0022] (4) Keep the above temperature for 120 minutes with stirring, continue to heat up to 100°C, keep it for 60 minutes, and carry out enzyme-killing treatment;
[0023] (5) Send it to a centrifuge for solid and liquid separation;
[0024] (6) The liquid part separated in step (5) is subjected to oil-water separation;
[0025] (7) Send the grease separated in step (6) into the heater, heat it to 120°C, then cool the grease to room temperature through the heat exchanger, and store it in the oil storage tank after inspe...
