It is widely used for the drying under low temperature of heat sensitive material which apt to be dissolved and polymer-ized or deteriorated under high temperature in pharmaceuti-cal,chemistry,foodstuff and electronic industries.
Features
The boiling point becomes lower when material put in the vacuum condition which enlarges the heat transmission strength of evaporator.So it can save heat transmission space for certain transmission quantity .Heat source is from recyclinglow pressure steam or waste hot steam and water. The evaporator is sterilized before drying, makes no foreign matters mixed in the process of drying. It is classified as static vacuum dryer and do little harm to the forms of target material.
Working Method
Vacuum drying means to make heat and dry target material which are put in the condition of vacuum. The drying time can be shortened if vacuum pump is used for moisture discharge.
Ps: If a condenser is accepted , the vaporized agent in the target materials can be recollected by condenser, if SK series liquid loop pump vacuum unit or ZSWJ water-jet vacuum unit is used, the condenser can be omitted to save energy and Investment.
