Spray Dryer


Spray Dryer

Overview

The spray drying is the technology widely used in the liquid technology shaping and in the drying industry. The drying technology is most suitable for producing the powder, particle or block solid products from the materials, such as: solution, emulsion, soliquid and pumpable paste states. For this reason, when the particle size and distribution of the final products, their residual water contents, the stacking density and the particle shape must meet the precision standard, the spray drying is one of the most desired technologies.

Principles

Spiral-shaped hot air evenly into the drying chamber. By passing through the high-speed centrifugal spray at the top of the tower, the material liquid will rotate and be sprayed into the extremely fine mist liquid beads.Through the very short time of contacting the heat air,the materials can be dried into the finished products. The finished products will separator. The waste gas will be discharged from blower.

Features

At a high speed of drying, after the spraying of the liquid material , the surface area of the material 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. Products with good uniformity, mobility and solubility, high purity, good 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 or particle products once a time. After the drying, there is no need for smashing and sorting, so as to reduce the operation procedures in the production and to enhance the 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 the control and management.
