Abstract

Abstract: Recovery of latent heat is one of the most efficient methods to reduce drying energy consumption. This paper presents a system to recovery exhaust latent heat for vacuum drying. Replacing water with heat conduct oil, a hydraulic Jet was employed to evacuate the dryer and compress the exhaust vapour. The heated vapour, which is increased its temperature and pressure by means of recompression, was transferred to the vacuum dryer as the heat source through a heat pipe. This design was confirmed by a series of experiments with oil sludge.
