Description

Technical Field

[0001] The utility model belongs to the technical field of food processing, and in particular relates to a quick-freezing production line. Background Art

[0002] With the development of social economy, the pace of work and life of urban people has accelerated, and people's requirements for material culture have been continuously improved. In recent years, convenient fast food has rapidly emerged in my country. Among them, quick-frozen food is made of fresh raw materials, which are properly processed and rapidly frozen to ensure the freshness and nutritional value of the food.

[0003] The quick freezing method uses a freezing device to quickly freeze food at a temperature of -23 to -30°C or lower. When food is frozen, the water contained in the tissue freezes quickly, and the ice crystal particles formed are small, which can reduce or prevent the destruction of food tissue and the loss of tissue fluid after thawing, thereby better maintaining the good texture and nutritional components of frozen food. At the same time, it is required to maintain a stable low temperature (below -18°C) during storage to prevent the increase of ice crystals.

[0004] First of all, the common quick freezing methods currently include the following:

[0005] 1. The ice cubes can be placed in a low temperature environment through a freezer, and the temperature of the ice cubes can be quickly lowered to achieve quick freezing. The temperature of the freezer can usually reach minus 18 degrees Celsius, which can quickly freeze the ice cubes to a solid state.

[0006] 2. Using liquid nitrogen is also a common quick-freezing method. The temperature of liquid nitrogen is very low and can quickly freeze ice cubes. Soaking ice cubes in liquid nitrogen can quick-freeze them in a short time.

[0007] 3. Use freezing spray, which can spray liquid gas on the surface of ice cubes, freezing the ice cubes through a rapid evaporation process.

[0008] However, the temperature of each quick freezing method is fixed and cannot be adjusted according to the product, which will result in different quick freezing methods having different effects on the quality and taste of the product (food), and may also cause different damages to the inside of the product (food).

[0072] Please continue reading Figures 1 to 13 When it is necessary to quickly freeze and preserve the packaged food, turn on the power of the equipment, set the quick freezing temperature and the speed of the conveying mesh chain 13 and the pressing mesh belt 14 in the quick freezing device 1 according to the required temperature of the quick frozen food, and at the same time, adjust the height of the pressing mesh belt 14 through the adjusting mechanism 17 according to the size and thickness of the product to meet the needs of different products, and then start running the equipment. The refrigeration unit 18 is running, and the quick freezing liquid in the quick freezing device 1 is circulated. After reaching the set temperature, the food is placed on the conveying mesh chain 13 and brought into the quick freezing box 11 and immersed in the quick freezing liquid for quick freezing. At this time, the temperature sensor 7 monitors the liquid temperature and the quick freezing effect of the quick frozen product in real time. At this time, the quick freezing temperature and speed can be adjusted according to the monitored temperature and quick freezing effect to achieve the best quick freezing effect. After the quick freezing is completed, the food is transported to the vibrating air-cooled dewatering device 2 through the conveying mesh chain 13 and the pressing mesh belt 14. At this time, the vibration motor 24 drives the filter screen 23 to vibrate, which can not only move the food packaging bag but also cooperate with the cold air fan 25 to remove the liquid on the packaging bag. At the same time, the rodless cylinder 333 of the box-taking mechanism 33 drives the placement plate 334 to enter under the upper turnover box 31 of the storage mechanism 32, and then the fixing mechanism of the storage mechanism 32 releases a turnover box 31 to the placement plate 334, and the rodless cylinder 333 places the turnover box 31 in the initial position to receive and load the dehydrated food into the turnover box 31, and automatically weigh the food. Then the box-pushing cylinder 341 works to push the turnover box 31 onto the conveyor 4 and transport it to the cold storage room 6. The adjustment component set in the cold storage room 6 automatically adjusts to the upper side of the turnover box 31 according to its own position and automatically grabs and stacks it.

[0073] When the quick freezing production line of the utility model is used, it comprises the following steps:

[0074] S1, the controller uses a PLC control system to automatically control the quick freezing device 1, the vibrating air cooling and water removal device 2, the automatic weighing and packing device 3, the conveying device 4 and the palletizing device 5, and automatically adjusts the refrigeration temperature of the refrigeration unit 18 of the quick freezing device 1 and the linear speed of the conveying mechanism 12 through the temperature information collected by the temperature sensor 7. First, start the device and set the type of food material to be quick-frozen through the controller;

[0075] S2, the control system automatically sets the matching quick freezing liquid temperature and the speed of the quick freezing line according to the set food material to achieve the best quick freezing effect;

[0076] S3, the height of the pressing mesh belt 13 in the quick freezing box 11 is set by the controller according to the size and thickness of the product, that is, the adjustment mechanism 17 provided on the quick freezing box 11 drives the pressing mesh belt 13 to move up and down to achieve height adjustment to meet the needs of products of different heights;

[0077] S4, the refrigeration unit 18 of the quick freezing device 1 arranged on one side of the quick freezing box 11 starts to operate, circulates the quick freezing liquid in the quick freezing box 11, and realizes rapid cooling of the liquid to reach the set temperature;

[0078] S5, putting the material into the quick freezing line and immersing it in the speed liquid for quick freezing, and the temperature of the quick freezing liquid is monitored in real time by the temperature sensor 7 arranged in the quick freezing box 11, and the quick freezing effect of the items is monitored. The control system compensates the temperature of the freezing liquid in real time through the refrigeration unit 18 through the collected temperature signal to ensure the constant temperature of the freezing liquid, and automatically adjusts the conveying speed of the conveying mechanism 12 to ensure the quick freezing quality of the product, and the qualified products enter the next process, and the unqualified products are circulated and quick frozen again;

[0079] S6, conveying the qualified material products in step S3 to the vibrating air-cooling dehydration device 2 for vibrating dehydration;

[0080] S7. After vibration and dehydration, the material products enter the automatic weighing and packing device 3. The control system automatically controls and realizes the precise placement of the turnover box 31, and weighs the product through the set weighing sensor 35, and feeds back the weighing data to the control system. Then the turnover box 31 is conveyed to the cold storage room 6 through the conveying device 4, and the material handling and palletizing are realized through the adjusting component and the grabbing component 53 of the palletizing device 5. At the same time, the data is recorded and saved in real time in the whole process, including the items, temperature, time of each step, packing quantity, storage time and specific storage and palletizing location uploaded to the control system, so as to realize the analysis and recording of the quick-frozen products and the traceability of the quick-frozen products in the later stage.

Therefore, the utility model is not limited to the specific implementations disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
