Single cone dryer is a commonly used solid material drying equipment, widely used in chemical, pharmaceutical, food and other industries. In order to ensure temperature control during the drying process, it is usually necessary to equip it with a cooling and heating device. This device can provide precise temperature control to ensure the efficiency and stability of the drying process.

1. Широкий диапазон температур:

•The temperature range is usually from room temperature to 200°C or higher.

•Some advanced devices can provide a lower temperature range, such as -20°C to 200°C, to meet different process requirements.

2. Высокоточный контроль температуры:

Adopt PID controller or other advanced temperature control technology to achieve high-precision temperature control.

•The control accuracy is usually ±0.1°C or less, ensuring temperature stability and consistency.

3. Heating and cooling capacity:

• Heating: Heat the heat transfer medium (such as thermal oil or water/glycol mixture) through an electric heater.
• Cooling: Cool the heat transfer medium to the required temperature through compressor refrigeration or cooling water circulation system.
• Select the appropriate heating and cooling capacity to ensure that the required temperature change is achieved in a short time.

4. Circulation pump:

• Circulate the heat transfer medium between the heating/cooling unit and the dryer to ensure uniform temperature distribution.
• The flow rate of the circulation pump should match the needs of the dryer, usually between a few liters per minute and tens of liters per minute.

5. Safety protection measures:

• Overtemperature protection: Automatically cut off the power supply when the temperature exceeds the set value.
• Overpressure protection: Prevent the system pressure from being too high.
• Leak detection: Detect whether there is a leak in the system.
• Emergency stop button: Quickly stop the system operation in an emergency.

6. User interface:

• Touch screen or digital display: Intuitively display the current temperature, set temperature and other parameters.
• User-friendly operation interface: Easy to set and monitor temperature, support programming and data logging functions.

1. Chemical industry:

• Drying various chemical raw materials and intermediates, such as catalysts, dyes, pigments, etc.
• Control the temperature during the drying process to ensure the quality and stability of the product.

2. Pharmaceutical industry:

• Drying drug raw materials and preparations, such as antibiotics, vitamins, etc.
• Accurately control the temperature to ensure the activity and stability of the drug.

3. Food industry:

• Drying food raw materials and additives, such as spices, condiments, etc.
• Control the temperature during the drying process to ensure the safety and quality of food.

4. Material science:

• Drying various powders and granular materials, such as ceramic powders, metal powders, etc.
• Control the temperature during the drying process to ensure the performance and consistency of the material.

The cooling and heating device of the single cone dryer needs to have high-precision temperature control (±1℃) and a wide temperature range (5℃ to 95℃). By choosing the appropriate heating and cooling capacity, circulation pump flow rate and high-precision temperature control system, accurate temperature control can be achieved, improving drying efficiency and product quality.
