Description

Technical Field

[0001] The utility model relates to the field of milk powder production and processing, in particular to a drying device for milk powder production. Background Art

[0002] Milk powder is a powder made by removing moisture from animal milk. It is suitable for storage. Milk powder is made from fresh cow's milk or goat's milk. It is made by removing almost all the moisture in the milk by freezing or heating, and then adding appropriate amounts of vitamins and minerals after drying.

[0003] Drying is a relatively important link in milk powder processing. Since milk powder particles are relatively small, the traditional bottom heating drying device easily causes the milk powder in the middle area to dry slowly, while the milk powder in the bottom area is closer to the heat source, causing the milk powder at the bottom to dry faster. As a result, when the milk powder in the middle area is not completely dried, the milk powder in the bottom area has already been burnt, resulting in poor drying effect of the milk powder. Summary of the invention

[0004] The utility model aims to provide a drying device for milk powder production, so as to solve the technical problem that the conventional bottom-heat drying device is prone to uneven drying, resulting in poor drying effect of the milk powder.
