Description

Technical Field

[0001] The utility model relates to the technical field of milk powder processing, in particular to a self-cleaning structure of a double-shaft paddle mixer for milk powder processing. Background Art

[0002] Milk powder is made from fresh cow's milk or goat's milk. It is made by removing almost all the water in the milk by freezing or heating, and then adding appropriate amounts of vitamins and minerals after drying. Milk powder is easy to prepare, convenient to carry, and rich in nutrition.

[0003] For example, a twin-shaft paddle mixer for milk powder production with the authorization announcement number "CN211302719U" can fill the evaporated material with residual moisture by using a heating plate, making the material softer and less likely to stick together. The material can be flipped by using a flip roller, so that the material can be heated evenly and the drying process can be accelerated. The two stirring rotors are staggered to stir the material more quickly and mix the material evenly. However, the device only mixes the milk powder through one set of equipment. It takes a long time to stir the mixing of one set of structures, which makes the processing time of the device longer and affects the working efficiency of the device. At the same time, the device is not convenient for automatic cleaning of the equipment. After completing one processing, there will be a certain amount of residue inside the device. When it is necessary to continue processing other types of milk powder, the internal equipment needs to be cleaned so as not to affect the next processing, making the device inconvenient to use.
