- Equipment Introduction
- Technical Parameter
- Working Principle
This kind dryer is belong to Vacuum type drying oven.In the drying chamber, material will be dried under vacuum condition. Under the vacuum condition, the boiling point of material
solution will reduce. It will increase impetus for heat and mass exchange. Therefore for certain heat exchange amount, it can save heat exchange area of evaporator Material is under
static condition during operation of the equipment, which is benefit for keeping initial status of material. Intermittent operation can adjust process conditions at any time .On the top of Low
Temperature vacuum dryer, heating system is arranged to tackle the problem of return of condensed water, in addition, air suction is arranged at the side to improve drying efficiency. This
equipment can be used for low temperature drying and organic solvent recovery. Heat source can be steam, hot water and thermal oil. It is specially suitable for drying materials that is
easily oxygenated during drying.
This machine is suitable for drying the material which is easy to decompose/polymerization under the high temperature and the degenerative heat-sensitive materials. Before
drying can take disinfects processing, to prevent intermingle materials during the drying process.This machine belongs to static type vacuum dryer, so dry material body won't damaged,
is widely used in pharmacy, food, chemical and electric industries etc.

This vacuum drier is designed with drying frame, which can be dismantled. Because of the raise of the hot wind, the heat is enough used to dry the material. Especially we adopts
double steam tubes (indirect, layered) to improve the uneven temperature in the former static vacuum drier. The sealing door of the vacuum dryer is designed to be the floating structure
and easy to open. The high vacuum degree makes the material dried more quickly at low temperature.
1. It can get higher drying capacity at lower temperature and the heat energy can be used fully.
2. It is suitable for materials such as heat sensitive and easy oxidizable material.
3. It can dry raw materials that contain solvent and which needs to be recovered.
4. Before drying, it can carry out disinfectant treatment. During the period of drying, any impurity can not enter it.
5. The dryer belongs to static drying, materials will not be damaged.
6. The machine is a kind of batch type operation and can adjust technical process at any time.
7. The inner top is designed arch structure, it can effectively avoid the condensed water drop back.
8. Vacuumize from 4 points to one point, can guarantee uniform drying.
