Two, product features:

1. Cuboid studio adopts high quality steel plate or stainless steel plate. Toughened, bulletproof double glass door to observe the objects in the working room at a glance.

2. The tightness of the door can be adjusted, and the whole silicone rubber door sealing ring is formed to ensure the high vacuum degree in the box.

3, microcomputer intelligent temperature controller, with setting, measuring temperature double digital display and PID self-tuning function, temperature control is accurate and reliable.

4. The heating power ratio can be adjusted arbitrarily to ensure that there is no temperature disadvantage in low-end temperature control.

5. TD102 series /TD102S series adopts flat plate heater, which is evenly distributed on the wall outside the studio; Other models use partition type heater, fast heating.

Studio materials

The electric vacuum drying oven can keep a certain vacuum degree in the working room, and the intelligent digital temperature regulator is used to set, display and control the temperature. The temperature regulator uses computer technology to collect and process the temperature signal in the working room, and the temperature in the working room can be kept constant automatically. The temperature control system is P.I.D intelligent temperature control, reliable performance, easy to use.

Four, the working principle of vacuum drying oven

Choice of vacuum pump

Note: 1. The table values are obtained under the following conditions: ① water temperature 15℃ : ② air 20℃ : ③ gas relative humidity 70% ④ atmospheric pressure 0.1013MPa. 2. The suction deviation shall not exceed ±10%

Compared with conventional drying techniques, it has the following advantages:

◆ Vacuum environment greatly reduces the need to remove the liquid boiling point, so vacuum drying can be easily applied to heat sensitive substances;

◆ For samples that are not easy to dry, such as powder or other granular samples, vacuum drying method can effectively shorten the drying time;

◆ All kinds of mechanical parts with complex structure of other porous samples after cleaning using vacuum drying method, completely dry after leaving any residual material;

◆ Safer use ---- under vacuum or inert conditions, completely eliminate the possibility of oxide heat explosion;

◆ Compared with the ordinary drying relying on air circulation, the powder samples will not be blown or moved by the flowing air;

Control features: with power failure, crash state data loss and protection of parameter memory, call recovery function.

Performance characteristics:

■ Adopt the first circular-arc design in China, the shell is made of cold rolled steel plate, and the surface is sprayed with static electricity.

■ The temperature control system adopts microcomputer technology, temperature control, timing, overtemperature alarm;

■ Dual-screen display with high brightness digital tube, accurate and intuitive display value, superior performance, touch key to set adjustment parameters;

■ The temperature sensor is the capacitive imported parts;

■ Imported motor and blade; With timing and timing functions;

■ The liner is made of stainless steel; Semicircular corners are easy to clean;

■ The door of the machine is completely elastic and can be adjusted by the user. The whole silicone rubber door sealing ring is formed to ensure the high vacuum degree in the box.

■ The studio of this machine is cuboid structure, so that the effective volume reaches the maximum, the door adopts toughened, bulletproof double glass door, so that the user can observe the studio culture items at a glance;

Five, the use of vacuum drying oven

Operating environment Requirements:

a) Temperature: 5 ~ 40℃

b) Relative humidity: ≤85%RH

c) Power supply voltage: AC220V±10%50Hz

d) No strong vibration and corrosive gas around

Vacuum debugging:

a) Close the door and tighten the door handle in place, close the discharge valve (make the hole on the rubber plug and the hole on the discharge valve twist 90 degrees away from each other), and open the vacuum valve (rotate 90 degrees counterclockwise). The vacuum valve may be tight in the first use, so you can rotate it forcefully.

b) Vacuum drying oven suction pipe (outer diameter :Φ16mm) and vacuum pump (2XZ-2 type, inlet outer diameter Φ16mm) are firmly connected with vacuum connecting pipe (models 6090 and 6210 have been connected) with random fittings (inner diameter :Φ16mm wall thickness :10mm). Turn on the vacuum pump power and start pumping air. When the indicator value of the vacuum gauge reaches -0.1Mpa, close the vacuum valve first and then the vacuum pump power to prevent the vacuum pump oil from flowing back into the working room. (The vacuum pump power on the panel can be directly closed for models 6090 and 6210 without vacuum valve.) At this time, the box is in a vacuum state.

True empty box debugging:

After vacuum debugging is complete, perform the following operations:

a. Turn on the power supply of the empty box, and the power indicator light should be on at this time (6090 and 6210 models should be turned on the thermostat switch respectively). The thermostat will perform power-on self-test, and the PV screen will display the temperature measured in the working room, while the SV screen will display the temperature set when leaving the factory. The AT and HEAT lights on the temperature controller should be on, indicating that the instrument enters the working state of heating.
