Problems solved by technology

[0004] There are many kinds of liquid egg pasteurization methods, but they can be summarized into two kinds: one is the mandatory external heating method, such as US4808425, 4739140 and 4417132, but there is a heating contact surface while this operation is feasible The problem of being easily contaminated, and the egg product itself is not evenly heated, which is likely to cause incomplete sterilization; the other is the radiation heating method, such as US5612076, which uses radio wave heating, and US4853238 also introduces a microwave heating method. This heating method can not only effectively and evenly kill harmful microorganisms in egg products, but also ensure that the functional properties of the lost products are not damaged
Far-infrared heating is also a method of radiant heating, but this is the first of its kind in the field of pasteurized liquid egg production

specific Embodiment approach

[0011] The specific embodiment of the invention The present invention is implemented through the following technological process:

[0012] The shelled eggs are cleaned, soaked and disinfected by chemical methods, the shells are broken, and the egg liquid is placed in a storage tank (1) with a stirring device, and the liquid eggs are stirred and mixed evenly in the storage tank and preheated to 45°C. The preheated liquid eggs are filled into the packaging box by the filling machine (2), and the packaging box is not sealed. The boxed liquid eggs pass through the far-infrared heater tunnel (3) sequentially through the conveyor belt, and the far-infrared heating process is carried out in the tunnel. Sterilization, during this process, the far-infrared rays emitted by the far-infrared heater have a wavelength of 3-10 μm, and the entire heating time is 2 minutes. The pasteurization temperature is controlled between 73-78 ° C, and finally sealed in the sterile room Machine seal, the...

Embodiment

[0013] Example: 100Kg of eggs, after surface disinfection with cleaning chemicals, are broken and shelled, the liquid part is placed in a storage tank with a stirring shaft, stirred and mixed, and preheated to 45°C. Then put the liquid eggs into the packaging box through the filling machine, but do not seal, and the boxed liquid eggs pass through the far-infrared heater tunnel successively through the conveyor belt for pasteurization. During this process, the far-infrared wavelength emitted by the far-infrared heater 4-9μm, the heating time of liquid egg products in the tunnel is 2 minutes, the pasteurization temperature is controlled at 75°C, the sterilized products enter the sterile room to seal, then cool to room temperature, and store at 0-4°C. This method is simple and easy to implement, and the shelf life of the produced liquid eggs is also greatly extended, usually reaching more than half a year.

Abstract

The present invention discloses the production process of pasteurized liquid egg product, and is especially production process of liquid egg product pasteurized in far infrared mode. During the production, liquid egg product in opened packing box is made to pass through one far infrared heating tunnel and pasteurized. Then, the pasteurized liquid egg product is packed in an abacterial packing room and cooled to room temperature before storage. The said production process sterilizes liquid egg product in package, can kill harmful microbes in egg product while maintaining the functional characteristic of the product, and the produced liquid egg product has long storage period.

Description

technical field [0001] The invention discloses a method for producing pasteurized liquid eggs, in particular to a method for producing liquid eggs through pasteurization by way of far-infrared heating. Background technique [0002] The basic particles of matter are composed of electrons, atoms or molecules. Even in the ground state, these particles are constantly moving, and this movement is carried out according to the inherent frequency of the substance. When these particles are subjected to a certain frequency When infrared radiates, if the frequency of infrared rays is exactly equal to the natural frequency of the basic particle, resonance will occur. At this time, the basic particle will not only undergo energy level transition, but also increase the amplitude, so that the internal energy will increase, so that the temperature of the substance itself will increase. raised. Because these thermal effects can make the material itself heated evenly, it can quickly and effe...
