Description

Eggshell and egg membrane separation system

This creation belongs to the field of automated production equipment, especially about an eggshell and egg membrane separation system, which has a consistent automatic process of secondary cleaning, crushing eggshells, primary drying, shell membrane separation and secondary drying. Separation of egg shell and egg membrane, which greatly improves the sorting efficiency.

According to statistics, eggs have always been the main source of supplementary protein for human beings. In addition to edible yolks and egg whites, egg shells are discarded as waste or used as fertilizers. In recent years, experts have conducted various studies on egg shells and found that egg shells that were originally considered waste have many available resources. Egg shells mainly include inorganic external minerals and internal organic substrates. The composition is calcium carbonate, and the organic matrix includes an inner membrane layer and an outer membrane layer. The inner and outer membrane layers are both composed of protein fiber networks, and the mineral part forms eggshells on them. The total protein content of the inner and outer membrane layers contains about 10% collagen, further identifying the collagen in the inner and outer membrane layers, where the adventitia layer is type I, and the intima layer is a mixture of types I and V , by immunohistochemical analysis found that X-type collagen was found in the inner and outer membrane layers, which indicated that the egg shell is of potential value.

Collagen is the main component in the human body as the collagen fibers that constitute the connective tissue cells. Especially in the biomedical field, collagen glue made of type X collagen can be used to fill corneal wounds, and there are also collagen fibers made of collagen. Skin and tissue replacement products, so the demand for collagen is also increasing; in addition, eggshells can also be used as compost, cleaning agents, etc., or eggshells can be processed through more sophisticated grinding techniques such as eggshell calcium. The health food is an excellent natural calcium carbonate. Calcium affects the bone health of adults and the height of children, and also affects the health of teeth. It can be seen from this that if collagen and calcium carbonate can be effectively separated from egg shells, manufacturing costs will be effectively reduced, utilization will be improved, and a major waste problem will also be solved.

For example, US Patent No. US 7,007,806 B2 "Method and apparatus for separating a protein membrane and shell material in waste egg shells" discloses a method and apparatus for separating a protein membrane and shell material in waste egg shells, including: A friction device for rubbing the connecting structure that attaches the egg membrane to the egg shell, so as to output the egg membrane and egg shell particles after friction; a liquid storage tank for holding a liquid, so that the egg membrane after friction And the passive dissociation of egg shell particles, so that egg shell particles sink, and egg membrane is floated and entrained in this liquid; an egg membrane recovery device, communicates with this liquid storage tank for recovering the floating egg membrane in this liquid; and an egg shell particle A recovery device, communicated with the liquid storage tank for recovering eggshell particles. However, when the above-mentioned invention is in use, because the liquid storage tank is not provided with stirring blades and cannot generate water flow, the egg membrane cannot be floated above the liquid storage tank, so it is unfavorable for the egg membrane recovery device to reclaim the egg membrane; Furthermore, In this case, only the specific gravity of the liquid in the liquid storage tank is used to allow the eggshell with a heavier specific gravity than the liquid to settle at the bottom of the liquid storage tank, while the egg membrane with a lighter specific gravity than the liquid floats above the liquid storage tank. The efficiency is quite poor.
