Description

Technical Field

[0001] This utility model relates to the field of quick-freezing equipment technology, and more specifically, to a quick-freezing equipment for cake-type foods. Background Technology

[0002] Quick-freezing equipment is a device that uses rapid cooling technology to quickly freeze food. It is widely used in the food processing industry. By lowering the temperature of food, it can quickly reduce the core temperature of food to below -18°C, thereby effectively inhibiting the growth of microorganisms and enzymatic reactions, and preserving the original color, aroma, taste, shape and nutritional components of food to the greatest extent. It is widely used in the quick-freezing processing of meat, aquatic products, fruits and vegetables, pastries and other foods.

[0003] For example, Chinese Patent Publication: A food quick-freezing equipment, application number: CN202211308057.9, includes a quick-freezing machine and a mesh conveyor belt. The mesh conveyor belt runs through the quick-freezing machine. A lifting structure is provided inside the upper cover of the quick-freezing machine. A cold air conveying device is installed below the lifting structure. The cold air conveying device is used to quick-freeze food located on the mesh conveyor belt. A pre-freezing device is provided above the lifting structure and at the entrance of the quick-freezing machine. A spraying device is symmetrically arranged on both sides of the mesh conveyor belt inside the quick-freezing machine. The spraying device sprays water mist when food on the mesh conveyor belt passes by. The pre-freezing device is used to pre-freeze the food and freeze the water mist, which can realize the rapid freezing of soup dumplings and other similar foods, reduce energy consumption, and improve production efficiency.

[0004] However, in the above-mentioned technical solutions, during the quick-freezing process of cake-type foods, since the conveyor belt generally operates in a low-temperature environment of -30℃ to -40℃, frost will continuously accumulate on the surface of the conveyor belt. This frost not only affects the operating efficiency of the equipment, but also becomes an ideal breeding environment for psychrophilic bacteria (such as Listeria monocytogenes, Pseudomonas, etc.). Psychrophilic bacteria are microorganisms that can grow in low-temperature environments. They multiply in the frost on the surface of the conveyor belt, thereby contaminating the food that passes through, posing a potential threat to food safety. Utility Model Content

[0005] The main objective of this invention is to provide a quick-freezing device for cake-type foods, which can effectively solve the problem in the background art where, during the quick-freezing process of cake-type foods, the conveyor belt generally operates in a low-temperature environment of -30℃ to -40℃, resulting in the continuous accumulation of frost on the surface of the conveyor belt. This frost not only affects the operating efficiency of the equipment but also becomes an ideal breeding environment for psychrophilic bacteria (such as Listeria monocytogenes and Pseudomonas). Psychrophilic bacteria are microorganisms that can grow in low-temperature environments. They multiply in the frost on the surface of the conveyor belt, thereby contaminating the food passing through and posing a potential threat to food safety.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a quick-freezing device for cake-type foods, comprising a quick-freezing device body, a conveyor belt provided on the quick-freezing device body, fixed plates provided on both sides of the quick-freezing device body, grooves provided on the fixed plates, scrapers and water absorption components provided in the grooves, air blowing nozzles provided between the scrapers and water absorption components, a placement groove provided on one side below the grooves, a water collection tank provided in the placement grooves, a hot air blower fixedly provided on one side of the quick-freezing device body, and air supply pipes provided on both sides of the hot air blower.

[0007] Preferably, the fixing plate is located directly below the conveyor belt, the inner wall of one side of the groove is inclined, and the scraper and the blower nozzle are obliquely and fixedly installed in the groove.

[0008] Preferably, the placement slot is located directly below the scraper, and one side of the air supply pipe is connected to the air nozzle.

[0009] Preferably, the water-absorbing assembly has a first rotating roller rotatably disposed in the groove, the first rotating roller is provided with a water-absorbing cloth, a motor is provided on one side of the first rotating roller, and a second rotating roller is provided on one side of the first rotating roller.

[0010] Preferably, the motor is fixedly mounted on the fixed plate, and the second rotating roller is rotatably mounted in the groove.

[0011] Preferably, the inclined surface of the groove is located below the first rotating roller.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) During the conveyor belt transport of cake-type food, the present invention scrapes off the frost layer on the surface of the conveyor belt by a scraper. The frost generated by scraping will fall into the water collection bucket under the action of gravity and be collected. At the same time, the hot air blower delivers hot air to the blowing nozzle through the air pipe, and then uses the inclined blowing nozzle to blow the hot air to the surface of the conveyor belt to melt the fine frost on the surface of the conveyor belt. Then, the motor drives the first rotating roller to rotate, and the first rotating roller drives the water-absorbing cloth to rotate, thereby using the water-absorbing cloth that is in contact with the conveyor belt to absorb the water stains on the conveyor belt. During the rotation of the water-absorbing cloth, the second rotating roller squeezes the water-absorbing cloth to squeeze out the water absorbed by the water-absorbing cloth. Then, the squeezed water falls on the inclined surface of the groove, and finally guides the water to the water collection bucket through the inclined surface for collection. This can effectively prevent the growth of psychrophilic bacteria on the surface of the conveyor belt due to prolonged frost, which would contaminate the food. Attached Figure Description

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 and Figure 2 As shown, a quick-freezing device for cake-type foods includes a quick-freezing device body 1, a conveyor belt 2 on the quick-freezing device body 1, fixed plates 3 on both sides of the quick-freezing device body 1, grooves 4 on the fixed plates 3, scrapers 5 and water absorption components 6 in the grooves 4, and air blowing nozzles 7 between the scrapers 5 and water absorption components 6. A placement trough 8 is provided on one side below the grooves 4, and a water collection tank 9 is provided in the placement trough 8. A hot air blower 10 is fixedly installed on one side of the quick-freezing device body 1, and air supply pipes 11 are provided on both sides of the hot air blower 10.

[0020] like Figure 3 As shown, in another embodiment of the present invention, the water-absorbing component 6 is rotatably provided with a first rotating roller 601 in the groove 4, a water-absorbing cloth 602 is provided on the first rotating roller 601, a motor 603 is provided on one side of the first rotating roller 601, and a second rotating roller 604 is provided on one side of the first rotating roller 601.

[0021] When it is necessary to absorb water stains on the conveyor belt 2, the motor 603 causes the first rotating roller 601 to rotate, which in turn drives the absorbent cloth 602 to rotate. The absorbent cloth 602, which is in contact with the conveyor belt 2, absorbs the water stains on the conveyor belt 2. While the absorbent cloth 602 is rotating, the second rotating roller 604 squeezes the absorbent cloth 602 to squeeze out the water absorbed by the absorbent cloth 602. The squeezed water then falls on the inclined surface of the groove 4 and is finally guided by the inclined surface to the water collection bucket 9 for water collection.

[0022] The working principle of a quick-freezing device for cake-type foods:

[0023] In operation, the cakes are first placed on conveyor belt 2, which moves them into the quick-freezing equipment body 1 for quick freezing. While the cakes are being transported on conveyor belt 2, scraper 5 removes the frost layer from the surface. The resulting frost falls into the collection tank 9 under gravity. Simultaneously, hot air blower 10 delivers hot air to blower nozzles 7 via air duct 11. The inclined blower nozzles 7 then blow the hot air onto the surface of conveyor belt 2 to melt the fine frost. The motor 603 rotates the first rotating roller 601, which in turn drives the absorbent cloth 602 to rotate. The absorbent cloth 602, which is in contact with the conveyor belt 2, absorbs water stains on the conveyor belt 2. While the absorbent cloth 602 is rotating, the second rotating roller 604 squeezes the absorbent cloth 602 to squeeze out the water absorbed by the absorbent cloth 602. The squeezed water falls on the inclined surface of the groove 4 and is finally guided by the inclined surface to the water collection bucket 9 for collection. This can effectively prevent the growth of psychrophilic bacteria on the surface of the conveyor belt 2 due to prolonged frost, which could contaminate the food.

[0024] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
