Description

Technical Field

[0001] The present invention relates to the technical field of abalone processing and production, and specifically relates to an automated production line for quickly removing the meat of quick-frozen abalone and its production process. Background Art

[0002] An abalone refers to a primitive marine shellfish, belonging to single-shell mollusks. It has only a half shell, with a thick, flat and wide shell. Abalone is a traditional precious food ingredient in China, ranking first among the four major seafoods. It has now become one of the classic state banquet dishes in China and is known as the ear of the ocean. During the consumption of abalone, it is often necessary to remove the shell of the abalone and take out the meat inside the shell to facilitate consumption.

[0003] Due to the different sizes and shapes of abalones, it brings great difficulties to the shelling work. Currently, the commonly used method for shelling and removing the meat of abalones is mainly manual operation, which has low efficiency, high labor intensity, is not suitable for large-scale production, and cannot guarantee the freshness and original flavor of abalones. Summary of the Invention

[0004] The purpose of the present invention is to provide an automated production line for quickly removing the meat of quick-frozen abalone and its production process to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An automated production line for quickly removing the meat of quick-frozen abalone includes a high-pressure shelling machine, a moving seat, and a placement frame. The moving seat is installed inside the high-pressure shelling machine through a slide rail. A receiving groove and an installation chamber are opened inside the moving seat. One side of the top of the moving seat is fixedly installed with an airtight door. An airtight airbag is embedded inside the airtight door. An air inflation pump is fixedly installed inside the installation chamber, and the air inflation pump is connected to the airtight airbag through a valve pipe. A rack groove is opened at the bottom of the moving seat. One side of the front of the high-pressure shelling machine is fixedly installed with a servo motor. The output end of the servo motor is fixedly installed with a gear, and the gear extends into the high-pressure shelling machine and meshes with the rack groove. The top of the moving seat is fixedly installed with a placement frame. Drainage holes are evenly opened at the bottom of the placement frame. An installation box is fixedly installed on the top of the high-pressure shelling machine. A high-voltage generator is installed inside the installation box. One side of the high-voltage generator is installed with a solenoid valve pipe that penetrates through and is connected to the top of the high-pressure shelling machine. A heat dissipation fan is fixedly installed on one side of the high-voltage generator.

[0007] A production process for an automated production line for quickly removing the meat of quick-frozen abalone. The production process steps are as follows: placing abalones → feeding and sealing → ultra-high pressure processing → high-pressure monitoring → discharging → screening and separation → quick-freezing → metal detection → sorting and packaging. The steps are as follows: including the following nine steps,

[0008] Step 1: Place the abalones inside the placement frame, and use the drain holes to convey the remaining water stains of the abalones to the inside of the receiving groove for collection;

[0009] Step 2: Energize and operate the servo motor to drive the gear to rotate forward. The forward-rotating gear cooperates with the engaged rack groove to drive the moving seat to move inside the high-pressure shelling machine, so that the sealed door coincides with the inlet on one side of the high-pressure shelling machine. Energize and operate the air inflation pump to inflate the sealed airbag through the valve pipe, so that the sealed airbag increases the sealing between the sealed door and the inlet on one side of the high-pressure shelling machine, and increases the sealed connection between the high-pressure shelling machine and the sealed door;

[0010] Step 3: Control the high-voltage generator to operate by the CPU controller to generate high-pressure gas. The high-pressure gas is conveyed to the inside of the high-pressure shelling machine through the solenoid valve pipe, so that a super-high-pressure environment is formed inside the high-pressure shelling machine. The super-high pressure can loosen the adhesion tissue between the abalone meat and the shell, gelatinize the protein between the abalone meat and the shell, lose elasticity and restraint, so as to achieve the purpose of easily shelling;

[0011] Step 4: Real-time monitor the air pressure safety value inside the high-pressure shelling machine through the pressure gauge. When the pressure gauge monitors that the super-high-pressure environment inside the high-pressure shelling machine reaches the set value, the CPU controller controls the high-voltage generator to stop running, ensuring the safety of the super-high-pressure environment inside the high-pressure shelling machine;

[0012] Step 5: After the shelling is completed, control the valve pipe and the servo motor to operate through the CPU controller. Deflate the sealed airbag through the valve pipe, and at the same time, the servo motor drives the gear to rotate in the reverse direction. The reverse-rotating gear drives the moving seat to extend out of the high-pressure shelling machine through the engaged rack groove;

[0013] Step 6: Move the placement frame to pour the separated abalones inside into the shell and meat screening machine. The shell and meat screening machine separates the abalone meat from the abalone shells, so as to achieve the purpose of quickly removing the meat from the abalones, and at the same time, rinse through the spray rinsing assembly;

[0014] Step 7: Convey the rinsed abalone meat to the inside of the freezing equipment for quick freezing. The quick-freezing temperature is -32°C and the time is 30 minutes, so that the central temperature of the abalone meat reaches below -18°C;

[0015] Step 8: Convey the frozen abalone meat to pass through the metal detector one by one, and operate according to the operation methods and supporting equipment specified by the metal detector to prevent iron or other non-ferrous substances from hiding in it;

[0016] Step 9: The abalone meat that has passed the metal detection is sorted by weight with an automatic sorter, placed in the inner packaging material, weighed, and then stored in a refrigerated warehouse at -18°C.

[0017] Further, a warning light 102 is fixedly installed on one side of the top of the high-pressure shelling machine 1, and a pressure gauge 103 is fixedly installed on the front of the high-pressure shelling machine 1.

[0018] Further, a sewage discharge pipe 5 communicating with the receiving groove 403 is fixedly installed on one side of the bottom of the moving seat 4. A valve plate 502 is movably installed inside the sewage discharge pipe 5. One side of the valve plate 502 is fixedly installed with an electric push rod 501, and the electric push rod 501 is fixedly installed on one side of the bottom of the moving seat 4.

[0019] Further, a cleaning mechanism 6 extending into the receiving groove 403 is fixedly installed inside the installation chamber 404. The cleaning mechanism 6 includes a servo motor 601, a lead screw 602, a lead screw nut 603, and a scraper 604. The output end of the servo motor 601 is fixedly installed with the lead screw 602, and the scraper 604 is installed on the outer side of the lead screw 602 through the lead screw nut 603.

[0020] Further, a protective box 8 is fixedly installed on the front of the high-pressure shelling machine 1. A CPU controller 801 is fixedly installed inside the protective box 8. A junction box 802 is fixedly installed below the CPU controller 801. The front of the protective box 8 is installed with a box door 803 through a hinge.

[0021] Further, when quick-freezing, the abalone meat can be pre-cooled to a temperature below 10°C, which can shorten the freezing time, reduce the production cost, and sterilize the pre-cooling area to ensure the hygienic safety of the pre-cooling area.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: An automated production line for quickly removing the meat of quick-frozen abalone and its production process. Through the ultra-high pressure shelling technology, the adhesion tissue between the abalone meat and the shell can be loosened, the protein in the abalone meat and the shell can be gelatinized, losing elasticity and restraint, so as to achieve the purpose of easily removing the shell. At the same time, it can also eliminate the pathogenic bacteria in the abalone products. The abalone shell and meat are automatically separated after being treated by the ultra-high pressure technology, saving a large amount of labor costs. While removing the shell, it can also ensure the integrity of the meat quality, kill bacteria and other microorganisms, providing hygienic safety guarantee for the abalone. In addition, the ultra-high pressure technology can also effectively inhibit the lipid oxidation of the abalone, effectively relieve the changes in flavor and nutritional components caused by lipid oxidation, and improve its sensory quality. The meat yield of the ultra-high pressure shelling and meat removal technology is increased, the meat quality is complete, greatly improving the work efficiency, reducing the production cost of abalone. At the same time, ultra-high pressure can effectively kill harmful microorganisms in aquatic products and inactivate endogenous enzymes. Under the condition of no additives, it can maximize the retention of its natural color, aroma, taste and nutritional components, meeting the needs of consumers for healthy, safe and fresh-tasting abalone, and more in line with the requirements of current green food.
