Description

Technical Field

[0001] The utility model belongs to the technical field related to drying devices, and specifically relates to a drying device for pellet feed production. Background Art

[0002] During feed production, pellets are often produced for animal consumption. Drying pellets is crucial in this process. Excessive moisture content significantly increases the likelihood of mold and mildew, while also hindering transportation and storage. Therefore, feed drying is essential. However, traditional drying methods involve placing the feed in a drying oven. During this drying process, the feed remains relatively static, resulting in uneven heating at different locations. Heat exchange rates are low at the feed's support locations, and the drying oven's single heat source results in low drying efficiency.
