When buying large vacuum ovens, Nanjing Jinling is the first choice in the industry.

Vacuum drying means placing the object to be dried under vacuum conditions, heating and drying, and using a vacuum pump to extract air and moisture, which speeds up the drying rate.
Note the use of a condenser, which can cool the extracted high-temperature and high-humidity air to a certain temperature and then generate condensed water into the buffer tank, thus effectively reducing the impact of water and air on the mechanical vacuum pump (i.e., rotary vane vacuum pump) and ensuring that the vacuum pump of durability. It is not necessary to use a condenser for water ring vacuum pumps.
Application: It is suitable for low-temperature drying of heat-sensitive materials that are easy to decompose, polymerize and deteriorate at high temperatures. It is widely used in pharmaceutical, chemical, food, electronics and other industries.
2. Main features
The boiling point of the material solution decreases under vacuum, which increases the heat transfer driving force of the evaporator. Therefore, for a certain amount of heat transfer, the heat transfer area of the evaporator can be saved.
The heat source for evaporation operation can adopt various methods (low-pressure steam, thermal oil, electric heating, hot water circulation heating).
The heat loss of the evaporator can be reduced.
. Suitable for drying heat-sensitive materials that are easy to decompose, polymerize and deteriorate at high temperatures.
Can be disinfected before drying. No impurities are mixed during the drying process, which meets the requirements.
It is a static vacuum drying oven, so the shape of the dried material will not be damaged.
3. Vacuum drying theory shows that
when the heating temperature is constant and the vacuum degree is increased, the drying rate can be accelerated.
When the vacuum degree is constant, increasing the heating temperature can speed up the drying rate.
By increasing both the vacuum degree and the heating temperature, the drying rate will be greatly accelerated.

6. Performance characteristics
The inner wall material of the vacuum drying box is made of stainless steel plate, and the outer front panel is made of stainless steel plate. The other parts are made of stainless steel plate. The internal seam welds are polished and polished. The vacuum degree is... Provide material warranty.
, Vacuum drying There are two observation mirrors in the front of the box to facilitate observation of changes in internal materials, and a wiring shield for the electric heater at the back.
The heating drying plate rack in the vacuum drying box is movable and can be taken out.
. The heating rack of the vacuum drying oven can be divided into multiple layers. Each layer is equipped with an electric heater group. There are only two electric heating tubes between them, which greatly increases the heating area.
The vacuum drying box is equipped with an internal air inlet and a nitrogen interface. An air guide hood is also installed so that the airflow entering the oven does not directly contact the material.
The door shaft of the vacuum drying oven adopts a plane bearing to ensure that there is no plane wear when opening and closing the door.
Vacuum drying All the inner corners of the box are made of smooth corners, with arched heights at the top and bottom, without burrs and unevenness.
The vacuum drying box is equipped with a vacuum gauge, a thermometer, a vent valve, a drain valve, and a nitrogen flow meter.
/> . The operating temperature of the vacuum drying oven is normal temperature ℃. The surface temperature is normal temperature + ℃ (higher temperatures can be customized).
