As shown in Figure 1, size A is the degree of depth of described dry liquid to heat conduction platform top; Size B is the width of described thermal trough; Size C is pallet avris thermal trough width; Described size B equals 2 times of settings of described size A; Described size C setting equal to described size A.
Thermal trough near dual side-edge edge in described pallet is provided with two.
Thermal trough in the middle of described pallet at least arranges one, and described heat conduction platform at least arranges two.
The size B of described thermal trough is set to one times of the dry liquid degree of depth, and object is described thermal trough is two heat conduction, can realize dry liquid like this and totally be heated evenly.
Described heat catalysis uses thermostatical circulating water, and heat transfer is even, thermal-stable, temperature precise control.
Vacuum drying frame in described pallet and vacuum drying chamber with the use of, insert formula assembling, be convenient to place with fixing, sabot coil conveniently with getting.
The appearance and size scope of described pallet is 300mm-1200mm.
Pass through technique scheme, the beneficial effect of technical solutions of the utility model is: be that the thermal trough of rectangle and heat conduction platform interval configure by adopting cross section, and optimize the size of described thermal trough and heat conduction platform, adopt corner to stack pin design, be conducive to laminated multi-layer, guarantee that dry liquid can thermally equivalent, improve heat conducting efficiency, thus making the residual water content of product even, vacuum drying efficiency is high, dry good product quality.
