Description

Technical Field

[0001] The utility model relates to the field of food brewing equipment, in particular to a material spreading and airing system. Background Art

[0002] In the traditional liquor production process, most companies require that the steamed materials be spread out to dry at 12-22°C. During the production process, a spreader is used to cool the materials to meet the process requirements. The existing material spreading method mainly uses natural wind to cool the steamed materials, but this method is only suitable for production in spring, autumn and winter. Due to the influence of factors such as weather changes, personnel operation level, and material status, the accuracy of process parameter control during the production process is relatively low. In summer, due to the high temperature, the production process requirements cannot be met, so the brewing workshop can only stop production in summer, resulting in relatively high operating and management costs for the company. Utility Model Content

Cooling the air at the inlet of the first air inlet pipe by the heat exchanger can increase the heat exchange temperature difference between the air and the material, thereby improving the heat exchange amount and heat exchange efficiency.
