1, High speed centrifugal atomizer spray dryer / food spray dryer / industrial spary dryer
Descriptions
The centrifugal spray dryer is 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, dairy products; detergent and surfactant; fertilizer, organic compound, inorganic compound and so on.
Principle Of Work
After filtering and heating, the air enters air distributor at the top of the dryer. The hot air enters the drying chamber in the spiral form uniformly. By passing through the high-speed centrifugal atomizer at the top of the tower, the material liquid will be rotated and sprayed into extremely fine mist liquid beads, through the very short time of contacting with hot air, products will be discharged continuously from the bottom of the drying tower and from the cyclone separator. The waste gas will be discharged by blower.
Application
High Speed Centrifugal Spray Dryer is widely used in foodstuff, pharmaceutical and chemical industry, such as egg powder, amino acid product, protein, blood, food flavor, food ingredients, pectin, carrageenan, spirulina, herbal extraction, pigment, cocoa, mushroom, PAC, malt dextrin, collagen, juice, yeast, Coffee, Creamer, coconut, milk, gelatin, gum and acacia etc.
Features
1. High speed of drying. After the spraying of the material liquid, the surface area of the material will be increased greatly. In the hot air flow, 95%-98% of water can be evaporated at the moment. The time of completing the drying needs only several seconds. It is especially suitable for drying the heat sensitive materials.
2. The final products own the good uniformity, mobility, and dissolving capacity. And the final products are high in purity and good in quality.
3. The production procedure is simple and the operational control easy. The liquid with the moisture contents 40-60%(for special materials, the contents may reach 90%.) can be dried into powder or particle products at a time. After the drying, there is no need for smashing and sorting, so as to reduce the operation procedures in the production and chance the product purity. The product particle diam enters, looseness and water contents can be adjusted through changing the operation codition in a certain scope, it is very convenient to carry out the control and management.
Outlines
1. Atomization: Atomizing system must ensure a uniform distribution of the fog drops, which is crucial to ensure a good qualified rate of products.
2. Contact of hot airflow and fog drops: when enough hot air enters into drying tower, the direction and angle of hot airflow have to be considered, no matter co-current flow, adverse current or mixed flow, must endure the sufficient heat exchange, it is crucial.
3. The angle design of pipelines and cone: It is very important to select the suitable angle, here we would like to share our experience and data from production of thousands of this equipment.

What is the different characteristic of centrifugal spray dryer from others ?
1. The tower body has cold wind jacket.
2. The tower body is provided with an automatic vibrating device.
3. The tower body, the pipeline is equipped with the quick opening cleaning hole and the sewage hole.
4. Automatic control of constant temperature feeding tank.
5. Manual high-pressure washing tower random accessories.
6. The part in contact with the material is made of stainless steel material (or all stainless steel manufacturing.
7. The material collection adopts the two-stage cyclone dust collector, or the first stage cyclone dust collector and the wet type dust collector.
8. Automatic control of inlet air temperature and continuous device.
9. Equipped with air sweep device.
Why choose the centrifugal spray dryer to drying ?
The drying speed is fast and the surface area of the liquid is greatly increased after atomization. In the hot air flow, 95% -98% moisture can be evaporated instantly. The drying time is only a few seconds, which is especially suitable for the drying of thermos-sensitive materials.
The product has good uniformity, fluidity and solubility, high purity and good quality.
Simplified production process, easy operation and control. For 40-60% moisture content (special materials up to 90%) liquid can be dried into powder products, control and management are very convenient.
