So-called vacuum drying is to dry materials in the vacuum conditions, heated drying. If the use of vacuum pump for suction smoke wet, speed up the drying speed.

Note: if use condenser, the solvent in the material through the condenser and recycling; If use SK series water ring vacuum pump, can need not condenser, save energy investment.

Vacuum under the boiling point of material solution is reduced, the driving force of heat transfer in the evaporator, therefore for certain heat transmission can save the area of heat transfer in the evaporator.

Evaporation operation of heat source can use low pressure steam or heat.

Less heat loss of evaporator.

Can be disinfected before drying processing, why don't contain pure material mixed with dry process, in line with the GMP requirements.

Mid-december/FZG square, round vacuum drying machine belongs to the static vacuum drier, so will not damage the dry material form.
