Spice Dryer,Seasoning Powder Spray Dryer Seasoning Spray Drying Tower

Technical Overview:

The centrifugal spray drying of seasoning powder is the most widely used process in liquid forming and drying industries. It is particularly suitable for producing powdered or granular solid products from solutions, emulsions, suspensions, and plastic paste-like liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density, and particle shape of the final product must meet precise standards, spray drying is an ideal process.

Technical Features of Seasoning Spray Drying Tower

The drying speed is fast. After the feed liquid is atomized by a high-speed centrifugal atomizer, its surface area is greatly increased, allowing it to evaporate instantly in the hot air flow.95％-98% moisture content, with a drying time of just a few seconds, making it especially suitable for drying heat-sensitive materials.
The product exhibits excellent uniformity, fluidity, and solubility, with high purity and good quality. The production process is simplified, and operation control is convenient. For moisture content...40—60％(Special materials are available.90％)The liquid can be dried into powdered or granular products in a single step, eliminating the need for crushing and screening after drying, thereby reducing production steps and improving product purity. The particle size, bulk density, and moisture content of the product can be adjusted within a certain range by changing operating conditions, making control and management very convenient.

Working Principle of Spice Dryer
System working principle:

The air, after being filtered and heated, enters the air distributor at the top of the dryer, where the hot air spirals uniformly into the drying chamber. The feed liquid passes through the high-speed centrifugal atomizer at the top of the tower,(Rotate)The liquid is sprayed into extremely fine mist-like droplets, which come into contact with hot air in a concurrent flow and are dried into a finished product within a very short time. The finished product is continuously discharged from the bottom of the drying tower and the cyclone separator, while the exhaust gas is expelled into the air by a fan.

Working Principle of the Nebulizer:
When the feed liquid enters the feed pipe of the atomizer, it is rapidly delivered to the high-speed rotating atomization disc after one or two distributions of the feed liquid. Due to the centrifugal force, the feed liquid spreads into a thin film on the surface of the rotating atomization disc and moves toward the edge of the disc at an ever-increasing speed. When it leaves the edge of the disc, the feed liquid is atomized, resulting in droplet, filament, and film fragmentation. Which type of fragmentation dominates depends on factors such as the rotational speed of the atomizer, the feed rate, the properties of the feed liquid, and the shape and diameter of the atomization disc. The droplet size is primarily determined by the peripheral speed of the atomization disc.
