Centrifugal Spray Dryer Manufacturers

            Centrifugal spray dryer is a kind of equipment that uses centrifugal force to atomize liquid materials and quickly dry them into powder or particles. It is widely used in food, chemical, pharmaceutical and other industries. Its basic working principle is to spray liquid materials into droplets through a high-speed rotating centrifugal nozzle, which will quickly dry after contacting with hot air to form powder or granular products.

Working principle of centrifugal spray dryer

1. Material atomization: Liquid material is pumped to the high-speed rotating centrifugal nozzle and sprayed into tiny droplets under the action of centrifugal force.
2. Hot air contact: The atomized material is fully contacted with hot air in the drying chamber, and the hot air is usually heated by a hot air furnace.
3. Water evaporation: Hot air quickly evaporates the water in the droplets, so that the material is quickly dried into powder or particles.
4. Finished product collection: The dried powder or particles are driven by air flow and collected by equipment such as cyclone separators or bag dust collectors.

Advantages of centrifugal spray dryer

1. Fast drying speed: Due to the large surface area of the atomized droplets and sufficient contact with the hot air, the drying process is rapid and usually completed within seconds.
2. Good product quality: The particles of the dried product are uniform and have good fluidity, which is suitable for producing high-quality powder or granular products.
3. Strong adaptability: It can handle a variety of different liquid materials, including solutions, suspensions and pastes, and is widely used in food, chemical, pharmaceutical and other industries.
4. Strong controllability: By adjusting parameters such as feed rate, hot air temperature and centrifugal nozzle speed, the particle size and humidity of the product can be accurately controlled.

Application Cases

    Food Industry:

• In the food industry, centrifugal spray dryers are often used in the production of milk powder, juice powder, coffee powder and other products. For example, a dairy company uses a centrifugal spray dryer to spray-dry fresh milk into milk powder, ensuring the nutritional content and taste of the milk powder and meeting the market demand for high-quality milk powder.

    Chemical Industry:

• In the chemical industry, centrifugal spray dryers are used to produce a variety of chemical products, such as dyes, pigments, catalysts, etc. For example, a chemical company uses a centrifugal spray dryer to dry liquid dyes into powdered dyes, which improves the stability and ease of use of the dyes.

    Pharmaceutical Industry:

• In the pharmaceutical industry, centrifugal spray dryers are used to produce Chinese medicine powder, antibiotics, etc. For example, a pharmaceutical company uses a centrifugal spray dryer to dry Chinese medicine extracts into Chinese medicine powder, which maintains the effective ingredients of Chinese medicine and facilitates the storage and transportation of Chinese medicine.
