As the name suggests, the spray drying machine is special equipment that adopts spray drying to produce dry powder from a liquid or slurry by rapid drying with a hot gas. Spray drying is the most economical method of evaporation to produce dried powders. In the market, powder spray drying machine is popular for powder drying processes. Compared to other types of drying machines, our fruit powder spray dryer machine can dry materials quickly with high quality, and low water activity for easier transportation and storage. Moreover, it can be widely used in the chemical industry, plastic resins, the food industry, ceramics, and so on.
1. In the food industry: fruit powder, milk powder, coffee, tea, eggs, cereal, spices, flavorings, etc.
2. Pharmaceutical: antibiotics, medical ingredients, additives, and so on.
3. Industrial: paint pigments, ceramic materials, catalyst supports.
After filtering and heating, the air is blown into the air distributor that is on the top of the drying machine. The hot air in spiral form enters the drying chamber. At the same time, liquid raw materials pass through the high-speed centrifugal sprayer on the top of the machine, moreover, they are rotated and sprayed into the extreme slim mist liquid beads. So the evenly and swirly distributed hot air completely contact with raw materials. In several seconds, the materials will be dried into a powder and discharged continuously from the bottom of the drying tower
1. Drying speed is fast: due to the enlarged surface of the material, 95%-98% of water can be evaporated instantly in several seconds. It is more suitable for drying thermal-sensitive materials to maintain the color, smell, and taste of raw materials.
2. High-quality final products: finished products featured with high purity, good uniformity, good flow capability, and solubility advantages.
3. Simple and stable operation, convenient to control and debug, easy to achieve automatic operation.
4. It is easy to replace the main parts and adjust the material staying time. Besides fruit powder, it is suitable for the chemical industry, plastic resins, the food industry, ceramics, and so on.
5. Suitable for large-scale food powder drying production. For small-scale food drying, you’d better choose a small hot air circulation drying oven.
♦ Feeding pump is to keep feeding smoothly
♦ The atomizer is driven by a motor directly with variable frequency control and imported bearings. The atomizer can make slurry vaporific continuously and evenly and enlarges the superficial area for heat exchange with hot air.
♦ The induced draft fan can help remove water steam out.
It adopts a primary filter and medium efficiency filter to ensure that the air used for drying is clean and filtered air.
The drying chamber consists of hot air volume, hot air distributor, air disperser, inner tower body, outer tower body, tower frame, discharge pipe, thermal insulation material, observing and cleaning door, lamp hole, etc.
The first cyclone separator can collect 80% powder and the other 19.8% can be collected by the second cyclone separator. The total collecting rate can be up to 99%.
Start the motor stable.
Note: If you need a small-sized spray dryer for the laboratory, we can supply you too.
