Hard bone liquefaction equipment and method for synchronously producing bone collagen polypeptides and ultrafine bone powder

Abstract

The invention discloses hard bone liquefaction equipment. The hard bone liquefaction equipment comprises an outer chamber, a first liquefaction chamber, a stainless steel cage and a second liquefaction chamber; an upper cap is arranged at the upper end of the outer chamber in a detachable way, and a lower sealing cap which can be opened / closed so as to have the outer chamber sealed is arranged atthe lower end of the outer chamber; the first liquefaction chamber which is capable of vertically sliding is coaxially arranged in the outer chamber; the stainless steel cage is coaxially arranged infirst liquefaction chamber; and a top surface of the second liquefaction chamber is fixedly connected to an outer side wall of the outer chamber so as to have the lower end of the outer chamber positioned inside the second liquefaction chamber. The invention further provides a method for synchronously producing bone collagen polypeptides and ultrafine bone powder on basis of the hard bone liquefaction equipment. The method for synchronously producing the bone collagen polypeptides and the ultrafine bone powder comprises the following steps: selecting hard bones, and carrying out crushing; carrying out first-stage liquefaction and second-stage liquefaction so as to obtain a liquid phase and a solid phase; performing centrifuging, concentrating and drying on the liquid phase so as to obtainthe bone collagen polypeptides; and performing drying, crude crushing and ultrafine crushing on the solid phase so as to obtain the ultrafine bone powder. The method for synchronously producing the bone collagen polypeptides and the ultrafine bone powder has the beneficial effects of being simplified in processing flow, improved in production efficiency, decreased in production cost and reduced inequipment investment.

Description

technical field [0001] The invention relates to a liquefaction equipment and a method for co-producing polypeptide and bone meal. More specifically, the invention relates to a hard bone liquefaction equipment and a method for co-producing collagen polypeptide and ultrafine bone powder, which belong to the technical field of food processing. Background technique [0002] Animal bones have a unique physiological function of supporting and protecting the body, resulting in their unique structure of "hard as cast iron, light as wood". Animal bone is rich in protein and minerals, and 40% to 45% of the protein that constitutes it is triple-helix collagen with a dense structure; in the minerals of the body, 99% of the total calcium content and 85% of the total phosphorus content are present In bone, and exists in the hard structure of hydroxyapatite. The research results show that general cooking and steaming cannot effectively extract the calcium in the bone, and the calcium in ...

Problems solved by technology

[0007] However, the above methods all have the problems of complex process, long time consumption, high production cost and large equipment investment.

The most commonly used hot-pressure extraction method in industry requires a large amount of solvent to be added during cooking, and finally needs to be concentrated and dried to remove it, which consumes a lot of water resources and energy
