Cavity structure of low-temperature drying furnace

The utility model belongs to the technical field of low-temperature drying equipment, and provides a cavity structure of a low-temperature drying furnace, which comprises a drying groove, and an air inlet duct and an air outlet duct are respectively arranged on one side of the drying groove. A hanging tool is further arranged in the drying groove and comprises a rolling barrel, and holes are evenly formed in the peripheral side of the rolling barrel. The side wall of the hanging tool is further connected with a driving assembly used for driving the hanging tool to rotate. The roller is arranged, the multiple sets of holes are evenly formed in the outer side of the roller, air enters the roller in an inner cavity mode through the holes in the roller, the area of the holes is smaller than that of an air inlet opening structure in the prior art, and therefore the overall air resistance is smaller, and workpieces are convenient to dry. 本实用新型属于低温烘干设备技术领域，本实用新型中提出的一种低温烘干炉的腔体结构，包括烘干槽，所述烘干槽一侧分别设置有进风道以及出风道；所述烘干槽中还设置有挂
