A complete set of new negative pressure extraction equipment for animal fats and oils with different processing capacity can be provided.

Animal oil production refers to the processing of animal suet, animal meat and intestine oil and meat mixture into animal fat. There are two processing methods, wet method and dry method.

Negative pressure refining process for animal fat

Refining method: Usually used for animal fat processing, it is considered to be a relatively complete processing method in terms of hygiene. The process flow mainly includes the following sections:

Unpacking and crushing section
After the raw materials are unpacked, they are transported by the conveyor to the crusher for crushing, and the crushed particles are in φ3-5mm;

Preheating and conveying section
In the preheating pot, the material reaches a solid-liquid mixed state. The preheating pot plays the role of material balance for the entire production line.

Negative pressure refining section
This process adopts a horizontal vacuum oil boiling pot, and the animal oil raw materials can quickly realize the separation of oil, water and residue in a vacuum state.

Vacuum dehydration section
The water molecules and peculiar smell micro-molecular volatiles in the raw materials are quickly separated from the raw oil and fat under a vacuum state, and flow into the tube condenser with the vacuum flow, and are condensed into distilled water under the cold water circulation and collected in the separator tank.

Oil residue separation section
This process uses a chain type oil residue separator to separate and drain the oil residue, effectively separating the surface oil of the oil residue.
The oil residue is transported to the oil press for squeezing.

Press section
The separated oil residue is pre-pressed by a horizontal screw extruder, and the pre-pressed cake is lifted by a conveyor to be pressed by a secondary screw press; the pressed oil cake enters the meat meal workshop;

Crude oil filtration section
Crude oil is pumped into a vertical blade filter through a sludge pump to filter, and the impurity content in the oil is below 0.2%. The separated oil residue is compressed by air, filtered by vibration, and then transported into the scraper to the oil press for squeezing;
