Hydraulic Atomization Spray Drying

Hydraulic atomization drying is to use an atomizing nozzle to accelerate the spraying of the raw material liquid through a tiny hole under high pressure, disperse it into droplets, and dry the droplets with hot gas (air, nitrogen or superheated steam) to obtain the product. The raw material liquid may be a solution, an emulsion, a suspension, or a molten liquid or a paste liquid. The dried product can be made into powder, granule, hollow sphere or pellet as required.

Therefore, hydraulic atomization drying is also an ideal process when the required particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet precise criteria.

RELAB is a professional supplier of hydraulic atomization drying nozzles, and provides the hydraulic atomization drying nozzles with different holes, materials and threads. As a key component of spray drying, it will be a primary task to choose a suitable nozzle.

The hydraulic atomization drying nozzle is aimed at the spray drying of general and low viscosity liquid materials. The spray drying technology has also been widely used in many fields such as chemistry, food, medicine, forestry, pesticides, ceramics, cement, metallurgy and so on.

Features of spray drying:

• It can handle solutions, suspensions, pastes and materials with various characteristics such as corrosiveness and high hardness.
• The drying time is short, the operation is convenient, and the running process can be automatically controlled.
• The heat utilization rate is high, and steam, electric heating, coal-fired, oil-fired, gas-fired furnaces, etc. can be selected according to the user's situation.
• It needs small space, good operating environment, and dust emission meets the requirements of national standards.
• The dried product has excellent quality, uniform particle size, good fluidity and uniform final moisture.
