Why do you choose the Shandong Leader Machinery Co.,ltd. vacuum drying oven?
1.Healthy! Pure mechanical squeezing craft maximally keeps the nutrients of the oil plants.No chemical substances left
2. High working efficiency! Due to a high working efficiency of the screw oil press machinery,both time and power can be saved.
3. Long durability! All the parts are made of the most suitable material and treated with refined crafts, such as cemented quenching and tempering to increase the hardness, consequently the durability.
4. vacuum drying ovenCost-effective! Low investment! The wearing parts on the oil press machinery such as the squeeze loop, squeeze spiral and squeeze bar are designed to be dismountable. When they are out of service period, users only need to replace them and there is no need to displace the whole machine.
Principle of work:
It is well known that vacuum drying is to put raw material into the environment of vacuum for heating and drying. If use vacuum pump to draw air and humidity out, the dry speed will be faster.
Note: if use condenser, the solvent in raw material can be recovered. If use SK series water ring vacuum pump or ZSWJ series hydraulic jet vacuum pump sets, condenser can not be used and the cost of investment could be saved.
Features
Under the condition of vacuum, the boiling point of raw material will decrease and make the pushing force become greater. Therefore for a certain amount of heat radiation, the conducting area of evaporator can be saved;
The heat source for operation of evaporation may be Iow pressure steam or surplus heat steam;
The heat loss of evaporator is little;
Before drying, the treatment of disinfection can be carried out. During the period of drying, there is no impurity material mixed in. It is in conformity with the requirement of GMP;
It belongs to static drier. So the shape of raw material to be dried will not be destroyed.

vacuum drying oven are continuous cross-flow drying equipment for large-scale production of low drying rate materials. The equipment is designed with a compact structure which required small installation area.
AAA1
The raw material can be spread on the conveyor belt through suitable mechanism such as star distributor, vibrating belt, grinder or granulator. The conveyor belt will pass the channel that consist one or several drying units. Each drying unit is equipped with air heating and circulating system, and each drying unit has one or several dehumidification system. The hot air will move up and down when the vacuum drying oven passes though.
AAA2
The material is distributed to the mesh belt evenly by the feeder. The size of stainless steel mesh is 12-16mm mesh. The transmission device will moves the mesh belt around the dryer. The dryer consist a several drying units and each unit has individual hot air circulation system. Part of the exhausted gas is exhausted by an exhaust fan. The waste gas is controlled by an adjusting valve. The hot air will move up and down when the material moving from the top layer to the bottom layer. This process will evaporate the water from the material when the mesh belt moves slowly. The running speed of the conveyer belt can be adjusted according to the material property. The dried material will be automatically discharged to a collector. The circulation units can be equipped according to the user’s requirement and the production demands.
