How to choose and configure an airflow dryer

When selecting and configuring an airflow dryer, multiple factors need to be considered to ensure that the equipment can meet production needs and achieve the expected drying effect. Here are some key steps and suggestions:

Clear drying requirements

• Material characteristics: Understand the properties of the material to be dried, such as moisture content, particle size, shape, thermal sensitivity, etc. These characteristics will directly affect the selection and configuration of the dryer.
• Production requirement: Determine the amount of material that needs to be dried per hour in order to select an appropriate specification of airflow dryer.
• Drying effect: Clarify the moisture content requirements of the dried material and whether further processing or grading of the material is necessary.

Select dryer model

• Select based on material characteristics:
• For materials with high moisture content, choose equipment with high water evaporation capacity.
• For heat sensitive materials, choose a low-temperature dryer to avoid damage from high temperatures.
• For high viscosity materials, consider equipping an efficient atomization system.
• Select based on production scale:
• The small laboratory spray dryer is suitable for the research and development stage.
• Large scale industrial production requires the selection of equipment with higher production capacity, such as the QG series airflow dryer.

Configure the dryer system

• Hot air source: Select appropriate hot air sources based on the conditions and needs of the production site, such as oil fired stoves, gas stoves, coal-fired hot air stoves, or steam heat exchangers.
• Atomization system: For materials that require atomization, choose an efficient atomization system to ensure that the materials can be evenly dispersed in the hot air flow.
• Collection system: Configure appropriate collection systems such as cyclone separators, bag filters, etc. to improve product recovery and air purification efficiency.
• Control system: Select a system with PLC control to achieve precise control and recording of parameters such as inlet air temperature, outlet air temperature, and frequency conversion.

Consider other factors

• Equipment investment and maintenance costs: Considering the investment and maintenance costs of equipment while meeting the drying needs, choose products with high cost-effectiveness.
• Ease of operation: Choose equipment that is easy to operate and maintain, reducing the difficulty and labor intensity for workers.
• After sales service: Understand the supplier’s after-sales service situation to ensure timely technical support and maintenance services during use.
