Structural description

Drying Oven Model forced air drying cabinet includes serial products. They are divided into two categories in appearance: desk-type and vertical-type. The desk type has a relatively smaller capacity, including three types of specifications: 30L, 70L and 120L. The vertical type has a relatively bigger capacity, including 200L, 420L and 620L. The shells of drying cabinets of all specifications are made of excellent steel plates and the surfaces have baking varnishes. The working room is made of stainless steel plates and has 2~5-layered shelves made of stainless steel wires (the middle layer is filled with extra-fine glass wool for insulation). The desk-type cabinet door adopts dual-layer tempered glass door; the vertical cabinet door has dual-layer glass viewing window in the top middle, through which the heating articles in the cabinet can be clearly observed. The connection between the working room and the cabinet door is installed with heat-resistant silicone rubber sealing ring in order to guarantee the sealing between the working room and cabinet door. The power switch, power indicator light, air door adjusting knob, temperature control instrument and other operating parts of drying cabinet are all located on the control panel in the front of cabinet body. For the desk type, the control panel is on the front left side of cabinet body; for the vertical type, it is on the front top side of cabinet body.

The heating constant temperature system in the cabinet mainly consists of motor with centrifugal impellers, electric heater, proper air duct structure and temperature control instrument. When switching on the drying cabinet, the motor rotates and vent upwards the heat produced by the electric heater (at the bottom of the cabinet) through air duct, which is absorbed into the fan after going through the articles to be dried in the working room. Such circulation continues until the temperature becomes even.

The temperature control instrument is a universal-purpose part made meticulously by our company. It is featured by the following functions: precise temperature control; the set temperature and the temperature in the cabinet are digitally displayed; the set temperature has protective device and tracking alarm. When the temperature in the cabinet is 10⁰C higher than the set temperature, the tracking alarm will switch off the power supply of the heater and send out the sound and light alarms.

Air door regulator can regulate the air inflow and outflow of the cabinet by starting up the air door adjusting knob.

V. Method of use

1. Put the articles to be dried into the drying cabinet, close well the door and turn the air door adjusting knob to “ ” position.

2. Move the power switch to “ON”. The power indicator light lights up and figures appear on the temperature control instrument.

3. Press and hold the temperature adjusting knob of temperature control instrument, the numeric temperature displayed at the moment is the set temperature. At the same time rotate the knob to select the required set temperature . When loosening the knob, the numeric temperature displayed at the moment is the temperature in the cabinet and the heating indicator light lights up, showing that the instrument has been in the heating and temperature-rising state. After a period of time, when the displayed temperature is near to the set temperature, the heating indicator light is flickering for many times. Under usual conditions, after heating for 90 minutes, the temperature control will be the constant temperature state.

4. When the required working temperature is lower, adopt the two-stage set method. For example, if the required temperature is 80⁰C, first set 70⁰C and after the overshoot temperature starts to drop back, then set 80⁰C, which can reduce and even eliminate the phenomenon of overshoot temperature, thus enable the inside cabinet to attain the temperature-constant state as early as possible.

5. Select the different drying times according to the different humidity of different articles, e.g., the articles to be dried are more humid, turn the air door adjusting knob to position so as to vent the humid air in the cabinet.

6. When the drying process being over, if not to immediately take the articles out, first turn the air door adjusting knob to close the air door, or let open the air door and move the power switch to “OFF”, then opening the cabinet door immediately to take out articles, but take care not to be scalded.
