After being processed to different degrees and methods, they become different types of meat foods. In order to increase the shelf life of meat products, freezing is often used for preservation, resulting in the need to thaw many meat products before eating. When thawing meat products, a meat food pretreatment circulation thawing device is required.

[0003] The thawing device in the prior art cannot effectively protect the interior of the thawing box from dust, which will cause dust and other impurities in the external environment to enter the interior of the thawing box through the ventilation pipe, thereby polluting the interior of the thawing box and further polluting the meat products. In addition, during the thawing process of the meat products, a certain odor will be generated, and the thawing device in the prior art cannot effectively adsorb and filter the odor, which will cause the odor to pollute the environment. Moreover, the placement box inside the thawing device in the prior art is generally integrated with the device, which will make it impossible for the staff to disassemble, replace and clean the placement box conveniently and effectively, which will cause bacteria to grow inside the placement box and the thawing box, reducing the overall practicality of the device.

[0004] Compared with the Chinese patent with publication number CN219719621U, the present utility model relates to the technical field of meat thawing, and in particular to a meat pre-treatment circulation thawing device, comprising a casing, an ultraviolet lamp is installed at the top of the inner part of the casing, a ventilation hole is provided at the top of the outer wall of the casing, an outer shell is fixedly connected to the left side of the outer wall of the casing, a flipping device is provided inside the outer shell, an auxiliary device is provided at one end of the flipping device, the middle of the inner part of the casing is fixedly connected to two guide plates, and an electric heating plate is installed inside the guide plate. Through the cooperation between the first electric push rod, the rack, the spur gear and the L-shaped plate, the first electric push rod is adjusted so that the output end of the first electric push rod pushes the rack downward, the rack rotates the spur gear, the spur gear drives the L-shaped plate to rotate, and the L-shaped plate drives the placement box and the lower placement box to rotate at the same time through the auxiliary device, thereby flipping the meat food, so that all positions of the meat food can be irradiated by ultraviolet rays, and the disinfection is more thorough.
