Embodiment 1
[0040] The production and processing technology of embodiment 1 refining snake oil
[0041] 1) Pretreatment: collect 90kg of snake fat and hair fat, refrigerate at 0-4°C, and crush to obtain small meat-like particles;
[0042] 2) Mixing: Mix the small particles of meat powder and rice husk in a weight ratio of 1:4 to obtain a mixture;
[0043] 3) Non-critical fluid extraction: Add n-butane to the mixture for extraction, the extraction pressure is 6MPa, the extraction temperature is 38°C, and the stirring speed is 35rpm; stand still for 45min to obtain n-butane extract;
[0044] 4) Vacuum limit de-butanization: collect the n-butane extract and transfer it to the evaporation tank for evaporation. The vacuum degree in the evaporation tank is -0.1MPa, the solution temperature in the evaporation tank is 55°C, and the desolvation time is 50 minutes. Evaporate to obtain Primary products of snake oil; residual n-butane ≤ 300mg / kg;
[0045] 5) Transfer to the desolvation and deodoriz...
