Low-temperature circulating grain dryer with filtering function

The low-temperature circulating grain drying machine with the filtering function comprises a base, a combustion bin and a drying bin, the combustion bin is mounted at one end of the top of the base through a fixing groove, a mounting table is mounted at the other end of the top of the base through a mounting groove, and a rotating motor is mounted at the top of the mounting table through a bolt; afixing plate is installed at one end of the bottom of the combustion bin through a connecting rod, an air blower is installed at the top of the fixing plate through screws, an exhaust chimney is arranged at the top of the combustion bin, and a bag-type dust collector is arranged at the end, close to the combustion bin, of the exhaust chimney. According to the utility model, flue gas generated bythe combustion bin can be conveniently discharged after being filtered, and hot air is not directly blown to the surface of grains, so that falling of the shell caused by too fast dehydration of the grains is prevented, the st
