Description

Technical Field

[0001] The invention discloses freezing equipment with special air circulation, breaking up and vibrating devices, and relates to the technical field of food processing, in particular to quick-frozen food processing equipment. Background Art

[0002] At present, quick freezers are mainly divided into spiral quick freezers, tunnel quick freezers and fluidized bed quick freezers.

[0003] Spiral freezers use a spiral method to transport products, occupying a small area while freezing large quantities of food. They are primarily used in the food freezing industry. Products within the spiral freezer are moved in a spiral motion on a conveyor belt, often using a horizontal air supply, allowing cold air to pass horizontally across the surface of the frozen product, cooling it.

[0004] Tunnel-type quick-freezing machines mostly use a structure in which the evaporator and fan are located above the conveyor belt, and the horizontal wind direction is adjusted to the vertical wind direction through the guide plate. The high-efficiency tunnel-type quick-freezing machines that have emerged in recent years use nozzles to blow the throttled cold air vertically downward at high speed onto the surface of the food, thereby achieving rapid cooling.

[0005] The fluidized bed freezer uses two conveyor belts to transport food. In the first section, cold air blows upwards through the food layer, rapidly freezing the surface. The air volume gradually increases to form a fluidized bed. In the second section, a fluidized layer is created to ensure free flow of food, achieving deep freezing of the product.

[0006] However, the above three quick-freezing machines have the following disadvantages:

[0007] 1. The horizontal blowing mode of the spiral quick freezer can easily cause the frozen products to move horizontally, especially for mixed granular frozen products, which can easily cause the frozen products to fall off the conveyor belt; it has an adverse effect on the sanitary environment in the quick freezing room, increases the difficulty of cleaning, and cannot solve the problem of product adhesion.

[0008] 2. For tunnel-type quick-freezing machines, since the evaporator return air outlet is located above the conveyor belt, especially for mixed particulate frozen products, they are easily adsorbed on the evaporator heat exchange fins, reducing production and causing pollution. In severe cases, the fin return air channel will be blocked, increasing the static pressure of the equipment and causing the fan to burn out.

[0009] 3. The wind direction of the fluidized bed quick freezer is to blow air upward from the bottom of the conveyor belt. For mixed granular frozen products, due to their different densities and sizes, the frozen products will be blown away and adhere to the inner surface of the air cavity, which may easily cause health hazards and increase the difficulty of cleaning.

[0010] 4. In addition, for frozen products with high moisture content, especially mixed granular frozen products, a large amount of frost will form on the evaporator fins as they cool. Since the thermal conductivity of the frost itself is low, the heat exchange efficiency of the evaporator will be reduced. At the same time, as the thickness of the frost layer increases, the return air space of the fins will be further reduced, resulting in an increase in static pressure and a decrease in wind speed, which further reduces the heat exchange efficiency.

[0011] In view of the problems existing in the above-mentioned prior art, especially for mixed granular frozen products, it is very necessary to design and develop a freezing equipment with special air circulation and breaking and vibration devices to solve the problems existing in the prior art. Summary of the Invention

[0012] Based on the actual problems of the above-mentioned existing technology in the quick-freezing chamber, such as products are easily blown away, cooled unevenly, easily stick together and agglomerate, and have low production efficiency, a freezing equipment with special air circulation and breaking up and vibration devices is provided, so as to achieve the purpose of improving the freezing effect of frozen products in the quick-freezing chamber, solving product adhesion and agglomeration, improving production efficiency, reducing product loss, and improving heat exchange efficiency.

[0013] The technical means adopted in the present invention are as follows:

[0014] A refrigeration device with special air circulation, a breaking up device and a vibration device comprises: a quick freezing chamber, a conveying device, a breaking up device, a vibration device, an ADF defrosting system and a refrigeration device;

[0015] Furthermore, the quick freezing chamber is an insulation chamber built with insulation panels;

[0016] Furthermore, a conveying device is arranged on one side of the quick-freezing chamber, and includes: an inlet driven device, a conveying mesh belt, and an outlet driving device; the inlet driven device and the outlet driving device are horizontally assembled on the inlet end and the outlet end of the quick-freezing chamber, and are linked by a conveying mesh belt, and the conveying mesh belt is divided into two layers, one in and one out, forming a loop; gears and reducers are added at both ends of the outlet driving device and the inlet driven device, and the operation of the entire conveying device is driven by the rotation of the reducer.

[0017] Furthermore, the breaking device is installed on the upper part of the upper conveyor mesh belt of the conveyor device near the entrance end of the quick-freezing chamber, and as the breaking device rotates, a small gap is formed between it and the conveyor mesh belt;

[0018] Furthermore, a vibration device is installed at the lower part of the upper conveyor mesh belt of the conveyor device near the outlet end of the quick-freezing chamber, and forms intermittent contact with the conveyor mesh belt as the vibration device rotates;

[0019] Furthermore, the refrigeration device includes: an evaporation chamber, a motor, a centrifugal fan, and an air duct chamber;

[0020] Furthermore, the main structure of the refrigeration device is arranged in the quick-freezing chamber and is parallel to the opposite side of the conveyor, and part of the structure is located above the conveyor; the evaporation chamber is mounted on the horizontal opposite side of the conveyor through a bracket; the interior of the evaporation chamber is communicated with the outside through the bottom, so that hot air passing through the conveyor enters the evaporation chamber; the inlet end of the air duct chamber is mounted on the top of the evaporation chamber, and the outlet end is arranged on the upper part of the transmission device; there are multiple centrifugal fans, which are evenly mounted on the upper part of the evaporation chamber and communicate with the interior of the evaporation chamber; the motor of the centrifugal fan is connected to the output shaft of the motor mounted outside the quick-freezing chamber through an extended shaft and a flat key, and the motor's electric fan blades rotate to make the cold air flow through the designated bellows to the food to be frozen;

[0021] Furthermore, the ADF defrosting system is arranged at the bottom of the evaporation chamber.

[0022] Furthermore, the dispersing device is installed on the upper part of the upper conveyor mesh belt of the conveying device near the entrance end of the quick-freezing chamber. As the dispersing device rotates, a small gap is formed between it and the conveyor mesh belt, which disperses and spreads the unevenly distributed products on the conveyor mesh belt at the entrance end, thereby preventing uneven cooling and agglomeration caused by product accumulation.

[0023] Furthermore, a vibration device is installed at the lower part of the upper conveyor mesh belt of the conveyor device near the outlet end of the quick-freezing chamber. Both ends of the transmission shaft of the vibration device are installed between the two conveyor mesh belts through bearing seats and are connected to the reducer. Driven by the reducer, the vibration device rotates. As the vibration device rotates, it forms intermittent contact with the conveyor mesh belt, and forms intermittent and regular knocking on the upper conveyor mesh belt, thereby vibrating and separating the frozen products to make them evenly distributed, further avoiding agglomeration.

[0024] Furthermore, a scraper plate made of copper material is provided next to the outlet drive device, and the products remaining on the conveyor mesh belt are scraped into the receiving tray through the scraper plate.

[0025] Furthermore, the air duct chamber is divided into a plurality of independent air cavities by partitions. The number of the air cavities is the same as the number of the centrifugal fans, and the air cavities are arranged in pairs. According to actual conditions, the air volume of each air cavity is different.

[0026] Driven by a centrifugal fan, the gas flows through the air duct chamber and is blown toward the conveyor belt in a vertical downward direction, cooling the products at the upper end of the conveyor belt. The air duct chamber is specially designed with an air escape channel to reduce the air flow pressure and improve the distribution of the product on the conveyor belt. The gas heated by the product flows through the conveyor belt and the air flow escaping through the air duct chamber escape channel is combined, then sucked into the evaporation chamber and cooled by the evaporation chamber. The gas is then sent back into the air duct chamber by the centrifugal fan, completing a complete air flow cycle.

[0027] In addition, the entire unit adopts the method of external motor, which reduces the volume inside the warehouse and reduces the amount of cooling consumed by the system to overcome the heat dissipation of the motor.

[0028] In the entire refrigeration cycle system, since the product needs to be frozen, the humidity of the air after the cold air and the product undergo heat exchange is relatively high. When passing through the bottom of the evaporation chamber, frost and ice are easily formed on the bottom and evaporator fins. The present invention adds an ADF defrosting device (Air Defroster) at the bottom of the evaporation chamber to achieve fully automatic injection of a pulsed, high-pressure, degreased, and dry high-pressure gas.

[0029] In the system, the product that needs to be frozen enters the conveyor belt through the inlet end. After a period of freezing, the granular product is broken up by the dispersing device and spread on the conveyor belt. After a period of transmission, the conveyor belt reaches the vibration device, and the vibration device forms intermittent and regular knocks on the upper conveyor belt to vibrate and separate the frozen product to make it evenly distributed and avoid agglomeration. A scraper plate is set at the outlet of the conveyor belt conveyor device to scrape off the product on the conveyor belt and prepare for the cleaning of the conveyor belt. The scraper plate of the present invention is particularly made of copper, and the scraper plate can be disassembled so that the scraper plate can be replaced when there is friction loss between the scraper plate and the conveyor belt. The use of copper material can prevent deformation when freezing special products.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] 1. The freezing equipment provided by the present invention has a special air circulation and a breaking and vibrating device, which is better than the air circulation system of the spiral quick freezer and the traditional tunnel quick freezer. The present invention adopts a method of discharging air through the sides of the food and the conveyor belt and a specially designed air flow escape channel. This method is more uniform than the air flow loop formed by horizontal air supply, and the frozen products are not easily blown away, thereby improving the air flow organization in the quick freezing chamber.

[0032] 2. The freezing equipment provided by the present invention with special air circulation, breaking up and vibration devices has better performance than traditional tunnel quick freezers. When freezing granular products, the products will not be adsorbed on the evaporator fins, avoiding the problem of granular products blocking the fin return air channel, thereby ensuring the normal use of the fan and extending the service life of the equipment.

[0033] 3. The freezing equipment provided by the present invention has a special air circulation and a breaking up and vibration device, which has a better freezing effect than the traditional fluidized bed quick freezer. For freezing mixed particles, the traditional fluidized bed quick freezer freezes the product in block form, and the core temperature often cannot meet the requirements, which also affects the product quality. The present invention adds a breaking up and vibration device, so that the product frozen by the system is granular, ensuring the freezing effect and product quality. The special airflow organization and ADF design also improve production efficiency.

[0034] 4. Compared with the above three quick-freezing machines, the freezing equipment provided by the present invention, which has a special air circulation, breaking up and vibration device, adopts an external motor method, which not only reduces the cooling consumption of the system to overcome the heat dissipation of the motor, but also avoids the hidden danger of motor oil leakage causing pollution to the internal environment of the quick-freezing chamber, thereby reducing energy consumption and ensuring indoor environmental hygiene.

[0035] 5. The refrigeration equipment provided by the present invention has a special air circulation and a breaking and vibrating device, and adds a pulsed, high-pressure, oil-removing, and drying ADF defrosting system, which slows down the formation of frost at the bottom of the evaporator and on the surface of the fins, improves heat exchange efficiency, improves airflow static pressure, and significantly extends the continuous operation time of the equipment, thereby achieving the purpose of reducing the frequency of defrosting, saving costs, and increasing production capacity.

[0036] In summary, the application of the technical solution of the present invention solves the problems existing in the prior art, such as poor airflow organization in the quick-freezing chamber, especially for mixed granular products, product adhesion and agglomeration, low production efficiency, high energy consumption, uneven cooling, etc. BRIEF DESCRIPTION OF THE DRAWINGS
