Abstract
Description
Technical Field
[0001] This utility model relates to the field of fluidized bed freezers, and in particular to a fluidized bed freezer with a cleaning structure. Background Technology
[0002] In the food processing industry, fluidized bed freezers are key equipment for rapidly freezing food and ensuring its freshness and quality. The cleanliness of their operating environment directly affects food safety and quality. With increasing consumer concern for food safety and increasingly stringent food production standards, the cleanliness requirements for freezers are becoming more and more stringent. When fluidized bed freezers freeze various types of food, the characteristics of different foods can lead to the formation of diverse and stubborn residues inside the equipment. During the freezer process of meat, meat scraps and oozing grease easily adhere to the structural crevices. After the grease solidifies at low temperatures, it forms hard dirt that is difficult to remove. Fruits and vegetables will produce debris and juices. After the juices dry, they form scab-like residues in the ventilation channels, directly obstructing the gas flow. These residues not only interfere with the normal operation of the equipment but also become a carrier for microbial growth, posing a potential threat to food safety.
[0003] Traditional cleaning methods require manual scraping to remove solidified grease and dirt from the surface of the convex plate, which can easily damage the surface and affect the service life of the equipment. For crust-like residues in the ventilation slot, the narrow space makes it difficult for cleaning tools to reach deep into the slot, and only repeated wiping with a fine brush can be used, resulting in low cleaning efficiency. Existing technology uses a cleaning tank under the conveyor belt, combined with a high-pressure water gun and nozzle to achieve multi-angle rinsing, and a dryer to remove residual moisture. However, if the rinsing pipe rotates too high, centrifugal force will cause the rinsing liquid to spray erratically and the pressure to fluctuate, resulting in localized excessive rinsing force and partial insufficient rinsing force. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a fluidized bed quick-freezing machine with a cleaning structure, which aims to improve the problem in the prior art that if the speed of the flushing pipe is too high, the centrifugal force will cause the flushing liquid to spray erratically and the pressure to fluctuate, resulting in excessive local flushing force and insufficient flushing force in some areas.

A cleaning pipe is installed on the top left side of the support frame, and a receiving groove is fixedly connected to the bottom left side of the support frame. A drain pipe is connected to the front side of the receiving groove.
[0010] As a further description of the above technical solution:
[0011] The maintenance mechanism includes a maintenance plate, the bottom of which is rotatably connected to the bottom left side of the quick-freezing machine housing, and a fixing plate is fixedly connected to the top left side of the quick-freezing machine housing.

After passing through the first evaporator, the cold air enters the static pressure box, allowing the airflow to enter the quick-freezing zone and blow onto the food at a stable and uniform speed, directly acting on the food to achieve rapid cooling. The blown cold air is guided by a guide plate to be transferred to the second evaporator, and then transferred to the air curtain machine for recycling. An air curtain is formed at the conveying outlet, which can block the outside hot air from entering the quick-freezing zone and avoid the loss of cold energy caused by heat exchange.

[0041] Working principle: When the mesh belt conveyor 3083 reaches the corner, it is rinsed by the cleaning pipe 2082 and the flushing pipe 206. The motor 203 drives the small gear 204 to rotate, which in turn drives the large gear 205 to rotate, thus causing the flushing pipe 206 to start rotating and rinsing. This reduces the speed of the flushing pipe 206, making the flushing liquid spray more stable and covering a wider range. Compared with the fixed flushing pipe 206, it can evenly rinse the surface and gaps of the mesh belt conveyor 3083. After the cleaning liquid falls into the receiving tank 2083, it can be discharged by the drain pipe 2084. At the same time, when the inside needs to be cleaned, the sliding positioning column 2093 can be slid to release the fixed state of the maintenance plate 2091 and open it to clean the inside, making it easier to remove stubborn impurities deposited in the receiving tank 2083.
[0042] The centrifugal fan 302 generates airflow power, which, after passing through the evaporator 303, enters the static pressure box 304 as cold air. This allows the airflow to enter the quick-freezing zone and blow onto the food at a stable and uniform speed, directly acting on the food to achieve rapid cooling. The cooled airflow still carries a certain amount of cold air, which is guided by the guide plate 307 to the evaporator 305, and then transferred to the air curtain machine 306 for recycling. An air curtain is formed at the conveying outlet to prevent hot air from entering the quick-freezing zone and avoid cold loss caused by heat exchange.
