Heat pump type double-fluid dehumidification temperature rising drying machine and drying chamber

Abstract

The invention discloses a heat pump type double-fluid dehumidification temperature rising drying machine and a drying chamber. The drying machine comprises a heat pump unit body with a refrigeration working medium loop and a control unit, a fan and a hot water pump, the refrigeration working medium loop comprises an air-cooled evaporator, a water-cooled condenser, a throttle valve and a compressorwhich are connected in series, the heat pump unit body is further provided with a humid air inlet, a drying air outlet, a hot water return port and a hot water output port, the humid air inlet, the fan, an air cooling channel of the air-cooled evaporator and the drying air outlet are communicated, the hot water return port, the hot water pump, a water cooling channel of the water-cooled condenserand the hot water output port are communicated, and the drying chamber comprises the heat pump type double-fluid dehumidification temperature rising drying machine. The drying machine has the advantages of small drying energy consumption, low use cost, high temperature adjustment precision, low moisture removal energy consumption, capability of meeting drying requirements of different dried objects on temperature requirements, good energy-saving and emission reduction effects and wide market application and popularization prospects.

Description

technical field [0001] The invention relates to heat pump drying equipment, in particular to a heat pump double-fluid dehumidification and temperature raising dryer and a drying chamber with the characteristics of dehumidification drying and temperature raising drying. Background technique [0002] At present, for wood, tobacco leaves, tea, grain, forest fruit drying, seafood products and other scenarios, the dryers used are all heating convection dryers, which will drive off the moisture of the dried material through heating and forced convection, so as to achieve the purpose of drying. However, the traditional heating dryer has the following problems: high heat loss due to dehumidification, high heating power consumption, weak humidity and temperature adjustment capabilities, and it is difficult to meet the drying requirements of different objects to be dried. Contents of the invention [0003] The technical problem to be solved by the present invention: Aiming at the ab...
