1 If you choose this way, it means that this supplier must be a very powerful supplier and capable. At present, no such supplier has appeared, and some are estimated to be fooling. The aggregate is crushed to pieces with an average size of 1-8cm, and the bone oil is extracted with benzene, petroleum ether, etc., so that the fat content in the aggregate is reduced to less than 1%, generally about 0.3-0.5%, and then The aggregates are made to each other in a rotating drum to separate the remaining meat and tendons on the surface. Then put it into the bleaching tank, add water and breathe in air. It dissolves in water to generate sulfurous acid, which has the effect of acid treatment in addition to bleaching effect. Part of the calcium in the aggregate is converted into calcium and dissolved in water, which can make osteoporosis and facilitate extraction with water. This process is commonly called bone-smoothing in some production enterprises. After processing and washing, it is sent to extraction. The extraction is carried out at a pressure of about 0.25 MPa, so the temperature is relatively high. The extractor is generally composed of 6 to 8 as a group, and the extracting liquid is flowed in reverse direction from tank to tank at regular intervals. The freshly charged extractor contains a concentrated extract. The extract is filtered and concentrated to about 50% by evaporation. After adding appropriate preservatives, it will be cooled to form a gel and dried to become bone glue.
