Working principle:
The solution, emulsion, suspension liquid or slurry are sprayed into fine beads in the hot air, going down from the top of the drying chamber to the bottom, the water will be evaporated to and the product becomes powder or granular product.
Induce hot air from the top of drying tower, at the same time, pump the material liquid to the top of the tower by screw pump or peristaltic pump, the feeding solution becomes into fine beads or small droplets through the atomizer. When the droplets meet the high temperature hot air, the water will be evaporated immediately, and the material liquid is dried into dry product in a very short time, the product is discharged from the bottom of the drying tower, or from the cyclone (depend on the configuration). When the hot air contacts with the droplets, the temperature declines significantly, and the humidity increases greatly, and then will be exhausted by exhaust fan. The fine powder in the air will be collected through different separating devices
There’re different fine powder separation and recovery devices, such as cyclone (the common type and various combination type), bag filter, cyclone + bag filter, cyclone + wet scrubber, and bag filter + wet scrubber etc. We should different fine powder separation and recovery devices as per the characteristics of product and requirements of customer.
Depend on the product features and requirements, we might install secondary drying and cooling system (such as ZLG vibration fluid bed or pneumatic transportation), formulation system or powder sieving system etc after the spray dryer, or dehumidifier.
Machine Introduction
spray dryer priceis a special equipment and is suitable for drying emulsion,suspending liquid,liquor and so on .Particularly it has unique for drying polymers and resins; dyestuff and pigment; ceramics, glass; derust agent; pesticide; carbohydrate, dariry products; detergent and surfactant; fertilizer, organic compound, inorganic compound and so on.
Working Priciple
Liquid material is pumped into the top installed rotary disc atomizer by mono pumpe and atomized into fine droplets inside the drying chamber. Heated and filtered hot air will be blown into the air distributor at the same time. The evenly and swirlly distributed hot air completely contact with the droplets for heat transfer. In several seconds, the droplets will be dried into powder and sucked out into the cyclone for discharging via exhaust fan.
Features
1.Dry faster, the general time is only 5-15 seconds, with instantaneous drying characteristics.
2.Materials take a very short period of time to complete the drying process, adapted to the dry thermosensitive materials, materials to maintain color, smell and taste.
3.Simplify the production process.The operational control is simple,which is suitable for control of production, wet 40-90% of the volume of liquid into a dry powder, reduce the crushing, screening processes.
