The drying of material；
3, heating source uses steam+microwave combination heat drying method, the purpose of general dried material under vacuum conditions
Dry≤5~2% moisture is needed, and most of water content of chemical products is combined using steam+microwave 3~0.5%
Heat drying method is energy saving than single microwave or single steam heat drying, section when 20~30% or more, list can also be used
One steam or the mode of micro-wave drying；
4, condenser, recover system are increased in vacuum system, for aqueous, solvent-laden heat sensitive material and are had
Harmful, oxidizable, the inflammable and explosive granular of poison, crystallization, unbodied material progress continuous vacuum conductive drying and（Or）It is cold
But, especially suitable, it can be to carrying out recycling beneficial to the gases such as poisonous and harmful, inert gas, oxidizable, inflammable and explosive；
5, drying temperature can be from 40 DEG C~120 DEG C arbitrary adjustings；
6, conveyer belt smooth running, reliable, heating surface area is uniform, conveying tape speed can be adjusted arbitrarily, and the number of plies may be configured as
1-10 layers；
7, can each layer conveyer belt of sample detection at any time moisture content, it is defeated that each layer can be adjusted at any time according to each layer moisture content difference
It send the speed of service of band or adjusts material charging rate；
8, the drying equipment that solid material is processed to improve rate of drying increases turn-down rig and processing solid material
With semi liquid state material cleaning device；
9, solid material and liquid material process equipment can be respectively set, and may also be arranged in same equipment.
The present invention be by long-term practice grope to sum up come science practicality technical solution, it have it is simple in structure,
The advantages that vacuum sealing is tight, good energy-conserving effect, operating cost is low, mobility is big, easy to operate, applicability is wide.
