Preferably, said attemperating unit comprises display and wind speed humiture mensuration probe; Said wind speed humiture is measured probe and is arranged on the insulation combined type tunnel body, records wind speed, humidity and the temperature of air in the insulation combined type tunnel body, and is sent to said display.
Preferably, be provided with vibrated bed in the said hothouse.
Compared with prior art, the present invention has following beneficial effect:
1, realized the combined drying of far infrared and heat pump; The low temperature drying air that utilizes heat pump to produce both can guarantee the dry mass of material; Can take away the moisture on material surface again fast; Infrared energy is mainly used in drive moisture motion from inside to outside, the vaporization of moisture is accomplished by heat pump with removing then, forms the integrated of mutual supplement with each other's advantages type.
2, through in hothouse, setting up vibrated bed; Operation through vibrated bed has increased material surface flow perturbation, makes the district's attenuation of material laminar surface flow, has improved material surface caloic exchange rate; Suitably the vibration frequency and the amplitude of adjustment vibrated bed can make material present fluidized state, reach the effect of fluidized drying.
3, the operation of vibrated bed improves the uniformity of dry indoor air flow, thereby improves the uniformity of dry materials; The operation of vibrated bed also can improve the operating efficiency of condenser and heat pump, can use the dry more material of lower operating temperature, reduces the energy consumption of unit output value.
