Animal oil negative pressure melting refining equipment production line：
1>Crushing pre-heating process：
Raw materials after grinding machine into pellet state,enters into the preheated pot, the purpose of preheating is to heat and mix raw material uses heat conduction oil to achieve a mixed liquid-solid state and suitable mechanical pump conveying,to reduce the resistance of the mechanical pump delivery,to reach the Pipeline transport process requirements. On the other hand, the preheater acts as a material balance for the entire production line.
2> Negative pressure melting and refining process:
The preheated pot preheated raw material into a solid-liquid mixed state,and into the melting pot, open the vacuum pump makes the cooker pot with negative pressure, heat conducting oil starts melting.
3> Vacuum dehydration recovery process:
Adopting water jet type vacuum jet pump to make negative pressure state in melting pot, vacuum tube supporting stainless steel tube condensation heat exchanger, vacuum condensation recovery system, evaporation of water vapor in raw materials, molecular mixture of odor molecules, volatiles under vacuum state from The raw material grease is separated and flows into the tube condenser catcher along with the vacuum pipeline.
4> Oil residue separation process:
The process adopts a stainless steel sieve type oil residue separator separate crude oil residue from the extract oil residue mixture, and the oil residue with the size larger than 0.5mm is sent to the pressing part through a scraper conveying device, the fine oil residue and the crude oil mixture are pumped into the filter machine process fine filtration.
