Beer is a very popular drink at present, and the market demand for beer is also expanding. Malt is the main raw material for beer production. During the production and processing of malt, it needs to be dried to ensure that the malt can meet the needs of beer production.

[0003] At present, malt is generally dried in an oven. Since the upper malt blocks the malt at the bottom, the hot air cannot evenly contact both sides of each malt, resulting in uneven drying of the malt. This will cause some of the dried malt to be unqualified, which increases the cost of beer production to a certain extent. Utility Model Content
