Problems solved by technology

Although this processing method cleans the surface of the eggshell, kills pathogenic bacteria and microorganisms, and coats the surface of the eggshell, there are many shortcomings in this processing method, which mainly include the following: (1) waste water (the cleaning process requires a lot of water); (2) not environmentally friendly (detergents, disinfectants enter the groundwater); (3) not low-carbon (drying, processing equipment requires energy); (4) higher production costs ( Including transportation, cleaning, film coating, drying, labor costs, equipment, management costs, et

Example Embodiment

[0021] Example 1 Preparation of clean and sterilized fresh eggs

[0022] In the laying hen farm, the clean eggs (clean eggs) and the "dirty eggs" are sorted into different containers on the artificial egg collector, and then the eggs with the clean eggshell surface are placed in the homemade clean and sterilized fresh eggs In the processing equipment (or use the equipment to produce "cleaning eggs") to complete the egg cleaning, remove cracked eggs, nest eggs, soft preserved eggs, special-shaped eggs and other eggs that are not suitable for long-term storage. Use the conveyor belt to enter the sterilization and dust removal process. During the process, the fresh eggs are rolled in a porous conveyor belt, while hot air blows on the surface of the eggshell in four directions, up, down, left, and right, to achieve the effect of sterilizing and removing dust on the eggshell surface. The wind speed is 3m / s, the temperature is 140℃, and the hot air blows. The time is 20s. The fresh eg...

Example Embodiment

[0024] Example 2 Preparation of clean and sterilized fresh eggs

[0025] The "clean and sterilized fresh eggs" processing procedure is the same as in Example 1, the difference is: ① Dirty eggs do not need to be sorted on the egg collector of the layer farm, but are completed in the egg inspection procedure. ②Do not use the fragrance process.

Example Embodiment

[0026] Example 3 Preparation of clean and sterilized fresh eggs

[0027] The "clean and sterilized fresh eggs" processing procedure is the same as in Example 1, except that: ①The hot air speed is 8m / s, the temperature is 160°C, and the hot air blowing time is 4s. ②The flavoring agent is an ethanol solution of rose essence.

Abstract

The invention relates to a method for producing clean sterilized fresh eggs. The method comprises the following steps: (1) rejecting dirty eggs, cracked eggs, sunken eggs, soft eggs and abnormal eggs, and isolating the clean eggs suitable for being stored for a long time; (2) hot air de-dusting and sterilizing: blowing the surfaces of the egg shells from up and down as well as left and right directions with the hot air at 120-160 DEG C, keeping the air speed being 2.5m/s-10m/s, and blowing each egg for 3-30 seconds; and (3) cooling and packaging: blowing the egg shells with the air at natural temperature, cooling the egg shells till the temperature of the egg shells is room temperature, and packaging, thereby acquiring the clean sterilized fresh eggs. The clean sterilized fresh eggs prepared by using the method provided by the invention have the advantages that the water and energy are saved, the chemicals such as detergent, disinfectant, coating anti-staling agent, and the like, are unnecessary, the matters inside the eggs are pollution-free, and the method is environment-friendly and safe.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a method for producing clean and sterilized fresh eggs. Background technique [0002] At present, there are two major parts of fresh eggs sold in the market, one part is unprocessed fresh eggs, and the other part is processed "cleaning eggs", also known as "clean eggs". [0003] Unprocessed fresh eggs are polluted by dirty eggs and damaged eggs. The surface of some eggs not only has feces, blood stains, feed, hay, protein, mildew and other visible dirt, but also has pathogenic bacteria such as E. coli and Salmonella. Bacterial contamination, the safety of fresh eggs is not high. For example, in August 2010, the Salmonella contamination incident occurred in the United States, thousands of people were infected by Salmonella, and as many as 500 million eggs were recovered. [0004] "Cleaning eggs" are processed fresh eggs, which refer to fresh poultry eggs that have been...
