How to control the temperature and humidity of the drying equipment?

Controlling the temperature and humidity of the drying equipment is the key to ensure the stability of the drying process and the consistency of product quality. The following are some specific control methods:

Temperature control
Constant temperature control system:
Drying equipment usually adopts constant temperature control system, which monitors the temperature inside the drying room in real time through sensors and automatically adjusts it according to the set temperature range.
When the temperature exceeds the set range, the control system will automatically start or shut down the heating system to keep the temperature stable.
Users can set the desired temperature value through the control panel and automatically adjust the heating power or cooling power according to the deviation between the actual temperature and the set temperature to realize precise temperature control.

Adjust the heating power:
The size of heating power directly affects the temperature inside the drying chamber. By increasing or decreasing the heating power, the temperature rise and fall can be accelerated or slowed down to meet different drying needs.

Air flow regulation:
Air flow is one of the important factors affecting the temperature in the drying room. Increasing the air flow can take away more heat, thus lowering the temperature; while decreasing the air flow will cause the temperature to rise.
Air flow can be controlled by adjusting the fan speed or damper opening.

Pressure Adjustment:
In some cases, the temperature can also be indirectly affected by adjusting the pressure in the drying chamber. Increasing the pressure can raise the temperature, while decreasing the pressure may lower the temperature.

Humidity Control
Constant Humidity Control System:
Similar to a constant temperature control system, a constant humidity control system monitors the humidity in the drying chamber in real time via sensors and regulates it according to a set humidity range.
When the humidity is out of the set range, the control system automatically starts or shuts down the condenser system to control the rise and fall of humidity.

Condenser cooling power adjustment:
By adjusting the size of the cooling power of the condenser, the rate of humidity rise and fall can be controlled to adapt to different drying needs.

Air Flow Control:
Good air flow helps to evenly distribute humidity to all areas of the drying chamber and exclude moisture-laden air, thus realizing humidity control.

Humidity Sensor and Feedback Control:
Humidity sensors are used to monitor the humidity in the drying chamber and feed this data back to the control system.
The control system adjusts parameters such as temperature, pressure, and air flow based on the feedback signals from the sensors to achieve precise humidity control.

Timing control:
The humidity of the dryer is adjusted by presetting different operating parameters during the time period. For example, a lower temperature and higher pressure can be used at the beginning of drying to quickly remove moisture, and then the parameters can be gradually adjusted to maintain the desired humidity.

Integrated control strategy
In practical applications, temperature and humidity control are often interrelated. Therefore, it is necessary to consider the above control methods comprehensively and develop appropriate control strategies according to specific drying requirements and product characteristics. At the same time, it is also necessary to pay attention to the precision and stability of the control system to ensure the precision and stability of temperature and humidity control. In addition, regular maintenance of the control system is also an important measure to ensure its normal operation and long-term stability.

In summary, through the comprehensive use of constant temperature and humidity control system, adjusting the heating power, air flow, pressure and condenser cooling power and other methods, the precise control of temperature and humidity of drying equipment can be realized. Correct temperature and humidity control can ensure the stability of drying effect and consistency of product quality, improve production efficiency and product competitiveness.
