Description

Technical Field

[0001] The utility model relates to the technical field of food freezing, and more specifically to a food freezing device with good freezing effect. Background Art

[0002] Liquid nitrogen quick freezer is one of the many freezing devices on the market that can provide good food freezing effect. In the liquid nitrogen quick freezer, liquid nitrogen is used to cool the air by contacting with liquid nitrogen, so that the food is quickly frozen to maintain the original quality, taste and nutritional content of the food. However, since the food itself contains a certain amount of moisture, water vapor is released during the rapid freezing process, resulting in frost inside. Frost will form an insulating layer on the surface inside the quick freezer, which will lead to a decrease in the heat exchange efficiency between the cold air of the refrigeration system and the food. The insulating layer weakens the cooling effect of the cold air on the food, and more energy is required to reach the required temperature, thereby reducing the overall cooling effect. Utility Model Content

[0003] In order to overcome the above defects of the prior art, the utility model provides a food freezing device with good freezing effect, so as to solve the problem that when a liquid nitrogen quick freezer freezes food, the inner wall is frosted due to the release of moisture from the food itself, resulting in reduced freezing effect.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a food freezing device with good freezing effect, comprising:

[0005] Quick freezing box;

[0006] A frost removal device, the frost removal device includes a mounting shell, a motor, a threaded rod, and a moving block, the mounting shell is fixedly mounted inside a quick-freezing box, the motor is fixedly mounted on the top of the mounting shell, the threaded rod is rotatably mounted inside the mounting shell, one end of the threaded rod is fixedly connected to the driving end of the motor, the moving block is movably sleeved on the outer surface of the threaded rod, the outer surface of the moving block is fixedly connected to a transverse scraper strip, the outer surface of the transverse scraper strip is fixedly connected to a vertical scraper strip, and a frost collection assembly is provided at the bottom of the inner surface of the quick-freezing box.

[0007] The frost collecting assembly comprises a carrier and a collecting drawer. The carrier is fixedly mounted on the bottom of the inner surface of the quick-freezing box, and the collecting drawer is detachably mounted on the bottom of the inner surface of the quick-freezing box.

[0008] Wherein, one end of the transverse scraping strip and the vertical scraping strip facing the inner wall of the quick-freezing box is conical.

[0009] It also includes a human-computer interaction terminal, a gas cylinder fixing device, and a liquid nitrogen bottle. The human-computer interaction terminal is fixedly connected to the outer surface of the quick-freezing box body, the gas cylinder fixing device is arranged on one side of the quick-freezing box body, and the liquid nitrogen bottle is detachably installed inside the gas cylinder fixing device.

[0010] Among them, the gas cylinder fixing device includes a fixed half frame, a detachable half frame, a pin groove, and a fixing screw.

The pin groove is opened on the outer surface of the detachable half frame, and the fixing screw is rotatably installed inside the pin groove.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the above scheme, the motor is controlled by operating the human-machine interaction end to start driving the threaded rod to rotate, so that the movable block moves downward under the limiting action of the mounting shell, thereby driving the horizontal scraper and the vertical scraper to remove the frost layer generated on the inner wall of the quick-freezing box. The scraped frost will eventually fall into the collection drawer. The staff can open the cabinet door and pull out the collection drawer for cleaning. Removing frost helps to improve the heat exchange efficiency between the internal cold air and the food. Utilizing the above structure, the frost layer on the inner wall can be scraped off without taking out the frozen food inside, thereby improving the freezing effect of the equipment.

[0013] In the above scheme, the staff can place the liquid nitrogen bottle inside the fixed half frame, then align the pin slot on the detachable half frame with the protrusion of the fixed half frame and insert it, and then turn the fixing screw to lock the fixed half frame and the detachable half frame to fix the liquid nitrogen bottle, so as to prevent the liquid nitrogen bottle from being placed randomly on the side and having the risk of tipping over. There is no need to remove the liquid nitrogen bottle when the device is moved. The above structure can reduce safety hazards and facilitate the movement of the equipment.
