The invention relates to the field of
drying, in particular to a multifunctional
humidity control
drying plant and a
humidity control manner. The multifunctional
humidity control
drying plant comprises a curing barn, and further comprises an air inlet door, a humidity discharging opening, a compressor, an
evaporator, a condenser, an auxiliary condenser, a crossed flow
heat exchanger, an air returning opening, an air outlet and a control module, and the auxiliary condenser is connected with the air returning opening; the condenser is connected with the auxiliary condenser so as to be connectedwith an internal circulation draught fan, the air outlet is connected with the curing barn, the crossed flow
heat exchanger is connected with the air returning opening so as to be connected with the air inlet door and the humidity discharging opening, and the
evaporator is connected with the humidity discharging opening so as to be connected with an external circulation draught fan; and the compressor is connected with the
evaporator, the condenser and the auxiliary condenser, and the control module is electrically connected with the compressor, the internal circulation draught fan, the external circulation draught fan, the air inlet door, the humidity discharging opening and the auxiliary condenser. By means of the multifunctional humidity control drying
plant, multiple humidity control manners can be achieved in the drying process, free switching can be achieved, and the aims of improving the drying efficiency and enlarging the applicability are achieved.
