Here are some ways to make bone meal:
1. The method of squatting. Generally suitable for rural families to make. Put the miscellaneous bone into the pot and add water to cook, or use a piece of quicklime, two parts of grass ash and water to stir, use the clear liquid to boil the bones, and then remove the fat and gelatinous material removed from the miscellaneous bone until The bones do not contain oil. Then the bones are dried and pulverized and then ground into powder.
2. Processing of coarse bone powder. (1) Crushing: The bone is pressed into small pieces and placed in a pot for 1-8 hours to remove the fat in the bone. When processing coarse bone meal, it is best to combine with the processing of bone oil and bone acid by boiling. In addition to obtaining bone powder, bone oil and glue can also be obtained. (2) Drying: After draining and drying, put it into a drying room or a drying oven and dry it at a temperature of 100-140 ° C for 10-12 hours. (3) Crushing: The dried bone is ground into a powder by a pulverizer or a stone mill to obtain a finished product. (4) Finished product specifications: The composition of bone meal varies slightly with the bone raw materials. The bone powder processed by fresh bone is generally 23% protein, 48% calcium phosphate, 3% fat, and 2% crude fiber.
3. Processing of steamed bone meal. The residue of the extracted bone oil is prepared by putting the bone into a sealed cylinder, introducing steam, and heating at a temperature of 105-110 °C. The oil is drained every 1 hour to remove most of the oil in the bone, and some of the protein is decomposed into a glue, which can be used as a raw material for the glue. The oil and fat removed by boiling and the bone residue of the glue liquid are dried and then pulverized to form steamed bone powder. The finished product is white and easy to digest, and has no special odor, but the protein content is less than that of crude bone powder.
