Specific implementation mode
The utility model will be further described below with reference to the accompanying drawings.
Systematic schematic diagram as shown in Figure 1, compressor 1 are sequentially connected first-stage condenser 2, secondary condenser 3, expansion mechanism
4 and evaporator 5, form circulation loop；
The outlet of high temperature drying room 8 and low temperature drying room 9 successively with 3 phase of air blower 10, evaporator 5 and secondary condenser
Even, setting evaporator drain mouth 11 on evaporator 5；
The air outlet slit of secondary condenser 3 is divided into two-way, is connected all the way with first-stage condenser 2, and another way is through air-introduced machine 27
