Description

Technical Field

[0001] The invention relates to the technical field of large yellow croaker prefabrication processing equipment, and in particular to large yellow croaker prefabrication processing integrated machine equipment and a prefabrication operation method thereof. Background Art

[0002] Yellow croaker (Pseudosciaena crocea) has a golden body, golden scales, red lips, and delicious meat. It is known as the "national fish" and is now the largest marine cage-cultured fish in my country. Yellow croaker is rich in nutrients such as protein and fat. Because the connective tissue in fish meat is less than that of livestock and poultry meat, the water activity is higher, so the fish meat is soft, tender, and tastes good. However, the nutrients in fish meat are easy to deteriorate, and the fish body is prone to carry more bacteria. Bacteria are easy to multiply in the fish body, causing the decomposition of protein and amino acids, producing bad odors and causing changes in flavor, causing the fish meat to rot.

[0003] The existing methods for pre-processing yellow croaker mainly focus on chilling or freezing, and some are processed into yellow croaker jerky (semi-dried yellow croaker). Currently, consumers have an increasing demand for convenient, nutritious and safe processed foods, and there is still great potential for the in-depth development and utilization of yellow croaker. Such pre-processing methods bring the following shortcomings: first, the fish meat is only cleaned, and on-site operators are still required to marinate the fish meat. Secondly, the existing pre-processing degree of fish meat is low. When packaged, the fish meat is still in a raw meat state, which reduces the convenience of eating. Summary of the invention

[0004] Technical issues solved In view of the above-mentioned shortcomings of the prior art, the present invention provides an all-in-one prefabrication and processing machine for large yellow croaker and a prefabrication operation method thereof, wherein three steps of vacuum pickling, packaging and precise slow cooking are arranged, and the large yellow croaker is driven to move according to the forward direction of the conveyor belt, wherein when in the vacuum pickling box, the internal conveyor belt structure is responsible for power transmission, and the drying lamp structure at the top can bake the large yellow croaker in motion, and the hot air blower structure at the top can transfer the high-temperature air generated by the drying lamp to the bottom end, and adsorb it to the outside through the exhaust assembly at the bottom end, thereby maintaining a high-temperature environment in the vacuum pickling box, which is convenient for the surface of the large yellow croaker to dry quickly and for the subsequent packaging steps, and the packaging assembly placed in the middle can pass through the packaging rack structure in the middle through the roller structures on both sides of the top end. Since the packaging rack is a hollow structure, when the hydraulic equipment at the top drives the heat-sealed packaging vacuum generating assembly to move downward, the packaging film in the middle can be brought into contact with the surface of the large yellow croaker, and the packaging rack and the two rollers are pressed down. The positioning head structure on the side compresses the buffer spring and the spring structure to play a role of buffer protection. After heat sealing and vacuum action, it can be driven to the tail end through the bottom conveying device. At this time, the surface of the large yellow croaker is covered with a layer of vacuum packaging film structure. When entering the precise slow cooking device, it is placed on the screen. By controlling the water temperature of the slow cooking device, the effect of low-temperature slow cooking is achieved. Therefore, when the device of the present invention is used, compared with the existing structure, the large yellow croaker is pre-processed in advance, and vacuum pickled and packaged are carried out to improve the actual effect of prefabrication, which is convenient for direct use on site after sale, and low-temperature slow cooking is carried out directly after packaging. Before sale, the fish meat is in a state of cooked meat, which improves the convenience of actual use on site, and can effectively solve the problem that in the prior art, the fish meat is only cleaned, and the on-site operator is still required to pickle the fish meat, and secondly, the existing fish meat has a low degree of pre-processing. When packaging, the fish meat is still in a raw meat state, which reduces the problem of on-site processing steps.

The top of the mounting frame 21 is provided with a hydraulic device 26. The bottom output end of the hydraulic device 26 is connected to a heat-sealed packaging vacuum generating component 261. The slow cooking device 3 includes a slow cooking bucket 31 and a screen 32 arranged in the slow cooking bucket 31. One end of the slow cooking device 3 and the heat-sealed packaging vacuum generating component 261 is electrically connected to the temperature control panel 27, and a physical control button structure is arranged in the temperature control panel 27. A vertical rod structure is provided at the end of the truss 22, and the sliding rod 222 is arranged in a groove body pre-opened in the middle of the vertical rod, and connecting rods 211 are fixed on both sides of the mounting frame 21, and two groups of trusses 22 are fixed on each group of connecting rods 211; each group of trusses 22 is a downward inclined structure, and the packaging frame 23 is a frame structure, and a horizontal groove structure is opened through the middle of the packaging frame 23, and its thickness is adapted to the thickness of the packaging film, and rollers 221 are fixed on both sides of the top of the mounting frame 21, and the packaging film on the rollers 221 passes through the horizontal groove in the packaging frame 23; the two ends of each group of springs 223 are respectively fixedly connected to the two ends of the truss 22 and the positioning head 224; the size of the heat-sealed packaging vacuum generating assembly 261 is adapted to the internal size of the loading frame 253; two groups of fan assemblies are arranged in the exhaust assembly 13, and the air passing plates 111 on both sides The middle part of the cover 121 is provided with a plurality of groups of hole groove structures; the drying lamp 121 is arranged in an equidistant array at the bottom end of the cover 121; the bottom column 251 is a column structure of two groups with different diameters, and the top of the bottom column 251 passes through the packaging rack 23; the two sides of the screen 32 are stuck in the slow cooking bucket 31; three steps of vacuum pickling-packaging-slow cooking are set, and the large yellow croaker is driven to move according to the forward direction of the conveyor belt 112, wherein when in the vacuum pickling box 11, the conveyor belt 112 structure inside it is responsible for power transmission, and the drying lamp structure at the top thereof can perform high-temperature baking on the large yellow croaker in motion, and the hot air blower 122 structure at the top can transfer the high-temperature air generated by the drying lamp to the bottom end, and adsorb it to the outside through the bottom exhaust assembly 13, thereby maintaining a high-temperature environment in the vacuum pickling box 11, which is convenient for the large yellow croaker surface to dry quickly and convenient for the subsequent packaging steps; The packaging component 2 placed in the middle can pass through the packaging rack 23 structure in the middle through the roller 221 structure on both sides of the top. Since the packaging rack 23 is a hollow structure, when the hydraulic device 26 at the top drives the heat-sealed packaging vacuum generating component 261 to move downward, the packaging film in the middle can be brought into contact with the surface of the rhubarb, and the packaging rack 23 and the positioning head 224 structure on both sides are pressed down, thereby compressing the buffer spring 252 and the spring 223 structure to play a role of buffer protection. After heat sealing and vacuum action, it can be driven to the tail end through the bottom conveying device 24. At this time, the surface of the yellow croaker is covered with a layer of vacuum wrapping film structure. When entering the slow cooking device 3, it is placed on the screen 32. By controlling the water temperature of the slow cooking device 3, the effect of low-temperature slow cooking is achieved. Therefore, when the device of the present invention is used, compared with the existing structure, the yellow croaker is pre-processed in advance, and then vacuum pickled and packaged, so as to improve the actual effect of prefabrication, facilitate direct use on site after sale, and directly perform low-temperature slow cooking after packaging. Before sale, the fish meat is in a state of cooked meat, which improves the convenience of actual use on site.

[0022] Embodiment 2: A prefabrication operation method of a large yellow croaker prefabrication processing integrated machine device includes a large yellow croaker prefabrication processing integrated machine device in embodiment 1, and the specific prefabrication operation steps are as follows: S1: Processing of large yellow croaker: ① cleaning, ② opening the back; S2: The large yellow croaker obtained in step S1 is vacuum pickled by the vacuum pickling component 1. S3: The large yellow croaker is transported to the packaging component through the conveyor belt at the bottom, and the packaging bag and the large yellow croaker are sealed and wrapped by the hot air packaging vacuum generating component therein; S4: The packaged large yellow croaker is transferred to a slow cooking bucket through a bottom conveying device for slow cooking at low temperature; S5: After the designated time, the large yellow croaker is fished out and collected.

[0023] Since the packaging rack 23 is a hollow structure, when the hydraulic device 26 at the top drives the heat-sealed packaging vacuum generating assembly 261 to move downward, the packaging film in the middle can be brought into contact with the surface of the large yellow croaker, and the packaging rack 23 and the positioning head 224 structures on both sides are pressed down, thereby compressing the buffer spring 252 and the spring 223 structure, thereby playing a role of buffer protection. After heat sealing and vacuum action, it can be driven toward the tail end through the bottom conveying device 24. At this time, the surface of the large yellow croaker is covered with a layer of vacuum wrapping film structure. When entering the slow cooking device 3, it is placed on the screen 32. By controlling the water temperature of the slow cooking device 3, the effect of low-temperature slow cooking (heating in a water bath at 70-76° for about 25 minutes after vacuum sealing) is achieved, thereby effectively solving the two problems raised in the background technology. Specific operation process of the process: 1. Cleaning: Clean fresh yellow croaker, remove scales, gills, and clean internal organs.

[0024] 2. Open the back: Place the cleaned yellow croaker on a stable workbench, and use a sharp knife to cut along the back of the fish from head to tail. Be careful not to cut it completely, and keep the belly of the fish connected.

[0025] 3. Tenderizing and marinating: Wash the fish fillets and dry them. Add 6 grams of salt and 15 grams of sugar, drizzle with a little salad oil, and marinate in the refrigerator for 2-4 hours.

[0026] 4. Take out the fish fillets and place them in the device, set the program, and perform vacuum marination and low-temperature slow cooking.

[0027] In actual operation, the temperature of the slow cooking device 3 and the heat-sealed packaging vacuum generating component 261 can be controlled by the temperature control panel 27 structure. The cooking loss rate of large yellow croaker at different water bath temperatures can be calculated by the formula (cooking loss rate = M1-M2 / M1*100%), such as Figure 1As shown in the figure, at a water bath temperature of 70°C, the weight loss rate of large yellow croaker was 12%, while at a water bath temperature of 72°C, the cooking loss rate was reduced to 9%. When the water bath temperature was 74°C, the cooking loss rate was the lowest, only 7%. Then the temperature continued to reach 76°C and 78°C in deep and high waters, respectively. The cooking loss rate of large yellow croaker increased to 12% and 10%, respectively. This shows that temperatures above 74°C will cause large yellow croaker to lose more water during the cooking process; Fig.11 shown.

[0028] In the present embodiment, ten sensory personnel scored the appearance, color, texture, taste and aroma of low-temperature large yellow croaker, and the average data were obtained; at a water bath temperature of 70°C, the sensory score of large yellow croaker was 70 points. At a water bath temperature of 72°C, the sensory score of large yellow croaker was 80 points. At a water bath temperature of 74°C, the sensory score of large yellow croaker was 90 points. At a water bath temperature of 76°C, the sensory score of large yellow croaker was 88 points. At a water bath temperature of 78°C, the sensory score of large yellow croaker was 78 points. The large yellow croaker cooked at water bath temperatures of 74°C and 76°C had the best overall score, with bright color, tender meat, delicious taste and strong fish flavor; the taste of large yellow croaker cooked at water bath temperatures of 72°C and 78°C changed slightly, and the fish flavor was lighter and had no peculiar smell; the sensory score of large yellow croaker cooked at a water bath temperature of 70°C was the worst; Fig.12 shown.

[0029] The hardness, viscosity, elasticity and adhesiveness of this batch of yellow croaker at different temperatures were obtained through the texture tester. Figure 3 It can be seen that hardness, viscosity, elasticity and adhesiveness can reflect the quality of large yellow croaker; combined with the data, it can be concluded that the comprehensive quality of large yellow croaker is best at a water bath temperature of 74°C. Fig.13 shown.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
