SU1477344A1 - Method of sanitary treatment of eggs - Google Patents

Abstract

This invention relates to the food industry, in particular to methods for preparing eggs before processing. The aim of the invention is to improve the quality and shorten the process time. Eggs are treated with a stream of 2–5% solution of hydrochloric or edible carboxylic acids with circulation rates of 3-5 for 1.5–3 min. Particles of a solid inert substance, such as fluoroplastic, are introduced into the solution, the ratio of the dimensions of which to the longitudinal axis of the egg is 0.03-0.05 with a volume concentration of particles of 0.2-0.35. The particles in the stream form a fluidized bed that cleans the surface of the shell from contamination.

Description

The invention relates to the food industry, in particular to methods for preparing eggs before processing them about

The aim of the invention is to improve the quality and reduce the duration of the process.

Etc. and measure 1 for sanitizing their eggs they are loaded onto a mesh conveyor, in which they enter a container with a 5% solution of hydrochloric acid. The container contains a false false bottom with a hole diameter of 1 mm, on which there is a layer of fluoroplastic particles, the diameter of which is 1.5 mm, the volume concentration 0.2 ". The tank is equipped with a piping system to create circulation of the solution and create a fluidized bed. An acid solution is supplied to the bottom of the tank under the grill by the pump, which at a speed of 0.03 m / s forms a fluidized bed of inert substance above the grill. Eggs that fall into this layer are washed by particles of an inert substance that cleans the surface of the shell from contamination. The processing time at this concentration is 1.5 min. direction for further use The solution, on the surface of which impurities in the form of foam accumulate, is discharged through the pipeline

and is directed to purification and regeneration. The multiplicity of circulation is equal to five within an hour.

Example 2 “For sanitizing eggs laid on a mesh conveyor, enter a container with 2% hydrochloric acid solution, equipped with a system for pumping a solution through pipelines into the lower part under a false grating bottom with 2.5 mm hole diameter . On the lattice there is a layer of inert particles with a diameter of 3 mm and a volume concentration of 0.35. When the solution is pumped, a fluidized fluidized layer of fluoroplastic particles is formed above the lattice by the pump. Eggs that fall into this layer are cleared of contaminants for 3 minutes and transferred by the conveyor for further processing as in Example 1. The contaminated upper part of the solution is removed from the tank due to the threefold circulation of the solution.

Example 3. To sanitize eggs, they are loaded onto a mesh conveyor and sent to a container with a 3% hydrochloric acid solution. The tank has a false bottom with a hole diameter of 2 mm, on which are particles of fluoroplast 2.5 mm in diameter and a bulk Concentration of 0.25o. The tank is equipped with a piping system for supplying the acid solution under the grid and circulating the solution. When the solution is pumped at a speed of 0.04 m / s, a fluidized bed of particles is created above the grate. Eggs, falling into it, are cleaned from contamination for 2 minutes. Purified eggs from the conveyor are transferred to further processing as in Example 1. The soils in the upper part of the solution are discharged from the tank due to fourfold circulation.

Example 4. A 5% hydrochloric acid solution is fed into a 1 m3 tank containing a lattice false bottom and equipped with a system for creating a circulating fluidized bed. After sorting the eggs with a longitudinal axis size of 57i7 mm, they are placed on a mesh conveyor and sent to a container. In a solution of hydrochloric acid, solid fluoroplastic particles with a size of

The duration of the process of sanitizing eggs is 1.5 minutes. Purified eggs are conveyed to the further operations for the production of egg melange a; freezing, warming, peeling and direction for further use.

Example 5. A 4% acetic acid solution is fed into a 1 m tank containing a trellised false bottom and equipped with a system for creating a circulating fluidized bed. After sorting the eggs with the size of the longitudinal axis, the mm is placed on the net conveyor and sent to the container. In the solution of acetic acid, solid particles of fluoroplastic with a size of

1.5 mm (t 0.03) and a volume concentration of 0.3 (- 0.3). To the bottom

A part of the tank under the grate is pumped by the solution of acetic acid, which forms a fluidized bed of fluoroplastic particles above the grate. The contaminants accumulating during processing are discharged with the upper part of the solution, which is being cleaned and regenerated, its circulation rate is four. The duration of the process of sanitization of eggs 3 min. The cleaned eggs are transported by the conveyor to further operations for the production of egg melange.
