Products Features
TOPTION's spray dryer adopts advanced technology and structural design, and has the following features:
1. Efficient drying: TOPTION's spray dryers use high-speed centrifugal spray technology, which enables liquid materials to be atomized into particles in a very short time and evaporate water quickly, thus improving drying efficiency.
2. Adjustable temperature: TOPTION's spray dryer adopts a PID temperature control system, which can adjust the temperature according to the needs of the material and effectively maintain the color, flavor, and nutrients of the material.
3. High Stability: TOPTION's spray dryer is equipped with a high-precision airflow regulation system, which can adjust the gas flow, pressure, and temperature in real time during the drying process, ensuring the stability of the drying process.
4. Easy to operate: TOPTION's spray dryer is equipped with an advanced touchscreen control system, which can realize automatic control and adjustment of drying parameters, easy and convenient to operate.
5. Wide range of applications: TOPTION's spray dryer can be widely used in many fields such as food, pharmaceutical, chemical, material, etc. It is suitable for drying various liquid materials.




Working Principle
TOPTION's spray dryer can meet the needs of various laboratory and industrial production, making it a reliable and high-quality drying equipment.
The liquid is filtered and heated and enters the nozzle distributor at the top of the dryer. The liquid enters the drying chamber uniformly in a spiral shape. By means of a high-speed centrifugal sprayer at the top of the tower, the material is rotated and rapidly sprayed into a very fine mist of liquid beads.
Through a very short contact time with the hot air, the material can be dried to the final product. The final product will be continuously discharged from the bottom of the drying tower and from the cyclone separator. The exhaust air is discharged by a blower.
With high efficiency, stability, easy operation, and a wide range of applications
Advantages
1. At a high speed of drying, after the spraying of the material liquid, the surface area of the material will be significantly increased. In the hot-air flow, 95%~98% of water can be evaporated at a moment. The time of completing the drying is only several seconds.
2. This is especially suitable for drying heat-sensitive materials. The production procedures are simple and the operation and control are easy. The liquid with a moisture content of 40~60% can be dried into the powder or particle products once a time.
3. The particle diameter, bulkiness, and moisture content of the product can be adjusted within the range by changing the operating conditions.


The application case

Application of coffee powder
Coffee powder preparation usually requires several processes such as selection, roasting, cooling, and grinding. Spray drying equipment can be used to transform the coffee liquid into dry coffee powder. The specific operation process is as follows: the coffee liquid is sprayed into the spray drying equipment, the nozzle sprays the liquid into a micro-fine mist, and these tiny droplets evaporate rapidly in the high temperature and high-speed hot air while forming a small particle size of coffee powder

Applications of milk powder
Milk powder is commonly used to make foods such as chocolate, desserts, bread, cheese, and beverages. Spray drying equipment converts liquid milk into dry powder, which makes it easier to store and transport. The spray drying equipment makes the milk liquid sprayed into the spray dryer to form a tiny mist, which evaporates the water by high temperature and high-speed hot air to form small particle sizes of powdered milk. These powders usually need to be sterilized at high temperatures to ensure food hygiene and safety
