Put the solid ** in the iron drum and bake and add the brain powder, suck it to the dehydration kettle with a vacuum rod, and heat the oil to 80 -90 to make it conducive to crystallization.
Step 2 Blending.
The oil phase with high and low brain content is mixed to achieve a controllable solubility in the third step of press filtration.
Impurities from the oil are removed by pressure.
Step 4 Crystallization.
Cool the oil first, and the inside is covered with a quilt including insulation. Cold brine is added, and mint crystals are formed after more than ten days. The separated ice oil is further put into blending, and the crystals are sent to the drying room to be heated to remove the components with low brain content.
