Efficient and automatic preserved egg pickling and feed liquid copper ion concentration real-time monitoring equipment and a preserved egg processing method

Abstract

The invention discloses efficient and automatic preserved egg pickling and feed liquid copper ion concentration real-time monitoring equipment and a preserved egg processing method. The equipment comprises a tank body, a batching pool, a feed liquid pretreatment box, a detection box, a sample chamber, a pure water pool and a waste liquid cylinder; a tank cover is arranged at the upper end of the tank body, supporting legs are arranged at the lower end of the tank body, a mounting plate is fixed between the supporting legs, and an equipment controller and a data processor are fixed at the upperend of the mounting plate. According to the efficient and automatic preserved egg pickling and feed liquid online detection device, full-automatic pickling of duck eggs is realized; the pickling efficiency of the duck eggs is improved; the content of metal copper ions in the pickling liquid is automatically detected; a computer control program can take corresponding measures in time; if the copper ion concentration is lower than a set value, the computer program can automatically control a metal salt mother liquor to be added into a set value range, so protein alkali damage liquefaction is effectively avoided, and if the copper ion concentration is higher than the set value, the program can prompt that preserved eggs need to be taken out of the tank in advance to prevent excessive eggshell spots.

Description

technical field [0001] The invention relates to the technical field of preserved egg production, in particular to a device for efficient automatic pickling of preserved eggs and real-time monitoring of copper ion concentration in feed liquid. Background technique [0002] Preserved eggs, also known as preserved eggs and bien eggs, are traditional flavored egg products in my country. The pickling process of preserved eggs is formed by the combined action of duck egg contents with alkali substances and other auxiliary materials, among which sodium hydroxide plays a major role, which gradually penetrates into the protein during processing to promote the coagulation of the protein. During the pickling process, metal compounds are added, the main purpose of which is to combine with the sulfur ions produced by the decomposition of protein in the egg to form insoluble salt sulfide and block the eggshell pores, hindering the continuous penetration of OH- into the egg, resulting in p...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing preserved egg pickling process is manually operated, and the atomic absorption method is used for conventional detection of copper ion content. The disadvantages are: special atomic absorption equipment must be used, and the equipment cost is high. It is difficult for general processing enterprises to configure equipment and personnel. If it is sent to the testing unit for measurement, it will be delayed and cannot guide production in time to avoid the problem of protein alkali damage or eggshell spots caused by too high or too low copper ion content, resulting in In order to solve the problem of economic loss, a kind of high-efficiency automatic pickling of preserved eggs and real-time monitoring equipment for copper ion concentration in feed liquid are proposed
