Abstract
A process to coagulate wasted eggs which includes an acidification step of the liquid egg, followed by a coagulation step using a heat exchanger, such as a scraped surface heat exchanger, and optionally a drying step. The obtained coagulated egg product has useful properties and can be used as animal food. The process allows the disposal of wasted eggs generated in the poultry and related industries and the production of a valuable by-product with high protein and fat content.
Claims20
A process for the production of a coagulated egg product which comprises, in order, the following steps:
- a) separating the liquid egg from the shells;
- b) acidifying the liquid egg product to a pH in the range of from 3 to 6.0;
- c) heating and coagulating the acidified liquid egg in a scraped surface heat exchanger.
An apparatus for the coagulation of wasted eggs which comprises:
- a) means for separating the liquid egg from the shells,
- b) means adapted to acidify the liquid egg to a pH in the range of from 3 to 6.0,
- c) a scraped surface heat exchanger for heating and coagulating the acidified liquid egg, wherein the scraped surface heat exchanger comprises a central shaft adapted to move axially back and forth,
- d) optional means for drying the coagulated egg, and
- e) optional means for reducing the particle size of the coagulated egg.
