Product Description

Description

Spray drying process is the widest used in the liquid forming process and in drying industry. The drying technology is most suitable for powder, particle products from materials, such as,solution, emulsion, SC and pumpable paste states material. For this reason, when the particle size and distribution of the final product, their residual water contents, the stacking density and particle shape must meet the precision standard, spray drying process is one of the most desired processes.

Principle

After filtering and heating, the air enters into air distributor on top of the Drying Equipment. The hot air enters into the drying room in spiral form and uniformly. By .passing through high-speed centrifugal atomizer on top of tower, the material liquid will rotate and be sprayed into the extremely fine mist liquid beads. Through the very short time of contacting with heating air, the material can be dried into final products. The final products will be discharged continuously from the bottom of drying tower and from cyclone separator. The waste gas will be discharged from exhaust fan.

Features

At a high speed of drying, after spraying of the material liquid, the surface area will be increased greatly. In the hot air flow, 95%-98% of water can be evaporated at a moment. The time of completing the drying needs only several seconds.

This is especially suitable for drying the heat sensitive materials. Its final products own good uniformity, mobility, dissolving capacity. And the final products are high in their purity and good in their quality.

The production procedures are simple and the operation and control are easy. The liquid with the moisture contents 40-60% (for special materials, the contents may reach 90%) can be dried into the powder of particle products for one time. After drying, there is no need for crushing and sieving, so as to reduce operation procedures in the production and to enhance product purity. The product particle diameters, looseness and water contents can be adjusted through changing the operation condition in a certain scope. It is very convenient to carry out control and management.

Application

Spray drying machine is a wide applied process in liquid process shaping and drying industry. Particularly it is suitable for producing powder, granule or block solid product from solution, emulsion, suspending liquid and pumped paste liquid. Therefore when the distribution of granule size, final moisture, bulk density, granule shape of finished product must be conformed to accuracy standard, the spray drying is an ideal process.

It's widely used in foodstuff, pharmceutical and chemical industry, such as egg powder, amino acid product, protein, pork blood powder, flavouring, pectin,herbal extract, pigment, and washing-powder etc.

2. Working principle of this kind drying equipment

After filtering and heating, the fresh air enter into the air distributor at the top of drying tower, distributed in spiral form uniformly. At the same time, the material liquid sucked by pump, and convey to the top atomizer, then spray to extremely fine mist liquid drop. Through the short time of contacting with hot air, the material moisture evaporated at once, so dried into final product. The finished product will be discharged continuously from the bottom of drying tower, and collected in the product tank in the bottom of cyclone separator. The waste air will be discharged outside by exhaust fan automatically.
