Description

Technical Field

[0001] The utility model relates to the technical field of coating devices, in particular to a silk protein fresh-keeping liquid coating device. Background Art

[0002] The coating preservation technology is to apply a layer of polymer liquid film on the surface of the fruit. After drying, it becomes a very uniform film, which can isolate the fruit from the air for gas exchange, thereby reducing the respiration of the fruit, reducing the consumption of nutrients, improving the hardness and freshness of the fruit, and reducing the rot caused by the infection of pathogens.

[0003] In the prior art, a Chinese patent with announcement number CN217364504U discloses a fresh-keeping coating device for preventing fruit from being damaged by collision. The device adopts a scheme of "comprising a fixed frame, a placement platform and a coating mechanism, wherein the coating mechanism comprises a height adjustment mechanism and a coating roller connected to the height adjustment mechanism, the height adjustment mechanism is slidably connected to the fixed frame along the longitudinal direction of the fixed frame, the placement platform is connected to the fixed frame, and the coating roller is arranged opposite to the placement platform". The scheme can effectively replace manual coating, meet the needs of batch coating of fruits, improve coating efficiency, and reduce the work intensity of staff.

[0004] However, the above scheme still has some shortcomings. For example, during the coating process of the preservative liquid, the coating device uses a coating roller of a regular shape to coat the fruit, while the surface of the fruit is not of a regular shape, resulting in the coating roller being unable to fully and evenly coat the surface of the fruit with the preservative liquid, thereby affecting the distribution of the preservative liquid after coating the fruit.
