Poultry egg shell-membrane separation technology

Abstract

The invention discloses a poultry egg shell-membrane separation technology. The shell-membrane separation technology comprises the following steps: firstly, preliminarily breaking the egg shells, allowing the broken egg shells to enter a centrifugal machine and separating egg liquid residues off the egg shells; then, washing the egg shells with clean water so as to thoroughly wash the egg liquid which is still on the egg shells after separation, and carrying out centrifugal separation again; allowing the dewatered egg shells to enter a shell-membrane separator, wherein hot-air inlet temperature of the shell-membrane separator is 160-185 DEG C and hot-air outlet temperature of the shell-membrane separator is 75-85 DEG C, so that the egg membranes are separated from the egg shells under the action of the hot air; the egg membranes enter a cyclone separator along with the hot air, the water vapor is discharged along with the hot air, the egg membranes are collected by a collector, and after drying, the collected egg membranes are packed and the packed egg membranes are warehoused; and the egg shells separated by the shell-membrane separator is sent into a dryer by a stranding cage, and then, the egg shells are dried, the dried egg shells are crushed, the crushed egg shells are packed and the packed egg shells are warehoused. The hot air utilized in the technology is prepared by heating air with hot steam through a heat exchanger. Industrial production of the poultry egg shell-membrane separation technology can be realized, so as to smoothly separate the egg shells and the egg membranes; moreover, the technology is simple and feasible, and causes no damage to the nutrients of the egg membranes due to the adoption of the physical changes.

Description

Technical field: [0001] The invention relates to a process for separating poultry egg shells and membranes. Background technique: [0002] The egg membrane is about 70μm thick and has a double-layer structure (the two membranes are separated to form an air chamber at the big end of the egg). Egg membrane contains about 90% protein, liposomes about 3%, carbohydrates about 2%, and egg membrane peptides. Its protein mainly includes collagen (mostly I, V, X type), OC17 (ovocleidin), siatoprotein (siatoprotein), OPN (osteopontin), ovalbumin (ovlbumin), lysozyme, Porphyrin (porphyrin). It has long been known to use egg membranes (commonly known as phoenix clothing) to treat bedsores, hand and foot addiction, burns, and dumbness. The unique effects of collagen in skin transplantation, corneal surgery, surgical suture, and ulcer treatment have long been discussed. Mix the egg membrane powder with the fiber material, and add proper amount of surfactant, dispersant, defoamer or thicken...
