Description

Technical Field

[0001] This utility model relates to the technical field of drying equipment, specifically to a spray drying equipment for a film-coated premix. Background Technology

[0002] Coating premixes are suitable for many food products, such as candy, chocolate, nuts, and meat products. Their use in ordinary foods can improve product quality, providing consumers with better taste and visual appeal. Coating premixes contain preservatives and freshness-preserving agents, which can effectively inhibit the growth of microorganisms, thereby extending the shelf life of food. They form a film on the surface of food, preventing moisture evaporation and enhancing the food's texture. Coating premixes may also contain food colorings and flavorings, which can increase the color and aroma of food, improving product quality.

[0003] Existing film-coated premix spray drying equipment typically involves placing the product inside the equipment, then spray coating it, followed by drying.

[0004] For example, a film-coating premix spray drying device with patent publication number CN222075890U can simultaneously perform film-coating premix spray drying on multiple products. It can automatically extend the inner frame from the spray drying chamber, making it convenient for workers to pick up and put down products. Moreover, the drive motor drives the screen to rotate, improving the efficiency of workers in picking up and putting down products. When spraying the film-coating premix, the rotation of the screen allows the product to be sprayed more evenly, and the product to be dried more efficiently and quickly, improving the coating quality of the product. Each layer of screen does not interfere with each other, making it convenient for users.

[0005] However, due to the complex structure of the device and the high requirements for material feeding operations, its practicality is insufficient. Utility Model Content
