Description

Technical Field

[0001] The invention belongs to the technical field of egg liquid processing, and particularly relates to an egg liquid processing method. Background Art

[0002] The egg liquid processing technology refers to a series of processes of collecting, cleaning and disinfecting eggs, crushing, collecting egg liquid, and disinfecting and storing egg liquid.

[0003] In the prior art, the collection, transportation, and storage of egg liquids often results in waste due to residual eggshells, inadequate temperature control during egg storage and transportation, and prolonged exposure of the egg liquid to air during transportation. This results in tens of tons of egg liquid being wasted annually in the existing egg liquid processing process. Furthermore, increased temperature during transportation, storage, and prolonged exposure to air accelerates egg deterioration. Once this occurs, the entire batch of egg liquid is discarded, and extensive manpower and material resources are required to disinfect all egg liquid transportation pipelines, containers, and processing equipment, resulting in significant economic losses.

[0004] Therefore, in order to solve the problems of residual egg liquid waste, insufficient egg liquid temperature control, and long-term contact of egg liquid with air in the existing egg liquid processing process, the present invention discloses an egg liquid processing method. Summary of the Invention

[0005] The present invention discloses an egg liquid processing method, which can recover the egg liquid remaining on the eggshell, and perform full-process sealing, temperature-controlled transportation and storage on the collected egg liquid, thereby ensuring that the egg liquid is always in a suitable temperature range and effectively reducing the contact time between the egg liquid and the air, thereby greatly delaying the deterioration speed of the egg liquid.

[0006] The present invention is achieved through the following technical solutions: A method for processing egg liquid comprises the following steps: Step 1: Egg pretreatment, which involves cleaning, disinfecting, and cannulating the eggs before cracking. Step 2: crushing the eggshells, recovering the residual egg liquid on the eggshells, and filtering the egg liquid; Step 3: Temperature control the entire egg liquid transportation process to ensure that the egg liquid maintains the calibrated temperature during transportation and storage; Step 4: pasteurize the egg liquid and then serve; Step 5: Filter the egg liquid twice before filling and storing.

[0007] In order to better implement the present invention, further, the step 1 specifically includes: Step 1.1: Load the eggs into the washing tank and wash the outside of the eggs with circulating water. The circulating water is clean water instead of recycled washing water. Step 1.2: Soak the eggs in water for disinfection, monitor the concentration of the disinfectant in real time, and adjust the soaking time of the eggs in real time according to the concentration of the disinfectant; Step 1.3: Soak, spray, and scrub the eggs with clean water; Step 1.4: Air-dry the eggs at 360° temperature control; Step 1.5: Canvas-check the eggs and remove any spoiled eggs.

[0008] In order to better implement the present invention, further, the step 2 specifically includes: Step 2.1, separating the eggs and crushing them to break the eggshells in half, collecting the first-level egg liquid; Step 2.2, tapping and vibrating the eggshells to collect the secondary egg liquid remaining in the eggshells, and filtering the secondary egg liquid; Step 2.3, checking the quality of the secondary egg liquid. If the quality of the secondary egg liquid meets the standard, the primary egg liquid and the secondary egg liquid are combined and collected; if the quality of the secondary egg liquid does not meet the standard, the primary egg liquid and the secondary egg liquid are collected separately; Step 2.4: Filter the collected egg liquid through a filter mechanism, and periodically disinfect the filter mechanism.

[0009] In order to better implement the present invention, further, the step 3 specifically includes: Step 3.1, transporting the egg liquid through the delivery pipeline, all the delivery pipelines and the containers on the pipelines are provided with a water cooling system, and the water cooling system is used to control the temperature of the egg liquid throughout the entire delivery process; Step 3.2: When transporting through a container, pre-check whether there is water accumulation inside the container, check the internal temperature of the container, and check the air tightness of the container. If all the container tests meet the standards, proceed to step 3.3; Step 3.3: Transfer the egg liquid to a container for temperature-controlled storage.

[0010] In order to better implement the present invention, further, the step 4 specifically includes: Step 4.1, preheating the egg liquid to 35±3°C; Step 4.2: transporting the egg liquid to a pasteurization system, heating the egg liquid to a pasteurization temperature range, and pasteurizing the egg liquid; Step 4.3: Cool the pasteurized egg liquid through a water cooling system and store the egg liquid at a controlled temperature.

[0011] In order to better implement the present invention, further, in the step 2.2, after collecting the secondary egg liquid, the eggshells are recovered and crushed, and the crushed shell residues are centrifuged to obtain the tertiary egg liquid.

[0012] In order to better implement the present invention, further, after completing the process of collecting and transporting a standardized amount of egg liquid, all pipelines and containers are cleaned and disinfected by CIP.

[0013] In order to better implement the present invention, further, in step 3, the calibrated temperature of the egg liquid during transportation and storage is 5-8°C.

[0014] In order to better implement the present invention, further, during the egg liquid transportation process, the pipeline pressure and flow are monitored in real time. If the detected pressure and flow are abnormal, the valve body, filter screen and plate on the corresponding pipeline are checked for blockage.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: (1) The present invention can recover the egg liquid remaining in the egg shell and shell residue during the process of egg crushing and egg shell pulverization, thereby effectively reducing the waste of egg liquid during the egg liquid processing process, and can recover tens of tons of egg liquid every year; at the same time, during the transportation and storage of the egg liquid, the egg liquid can be sealed and temperature-controlled during transportation and storage, so that the egg liquid is maintained in an appropriate temperature range throughout the entire transportation, storage, warehousing and outbound processes, and the contact time between the egg liquid and the air is significantly reduced, thereby greatly delaying the deterioration rate of the egg liquid and avoiding the deterioration of the egg liquid during the entire processing process.

[0016] (2) The present invention solves the original problem of precise control of egg liquid temperature, achieves the purpose of sterilizing egg liquid within a certain period of time in a closed environment, and effectively kills and controls microorganisms and miscellaneous bacteria in the egg liquid, thereby greatly improving the edible safety and storage period of the egg liquid.
