AI Technical Summary
In existing dehydrated vegetable drying processes, waste heat is directly emitted, resulting in wasted heat, and the shredded vegetables are prone to clogging of the recovery pipes during drying.
A device comprising a drying chamber, a storage chamber, an exhaust fan, a stirring rod, and a rubber scraper was designed. The exhaust fan draws the residual heat from the dried air into the storage chamber for preheating. The stirring rod and scraper work together to prevent vegetable fragments from entering the recovery pipe, thereby achieving the recovery of residual heat and uniform drying of the vegetables.
This technology enables the recovery and utilization of waste heat, shortens drying time, saves energy, prevents blockage of the recovery pipe, and improves the efficiency and effectiveness of vegetable drying.
