Centrifugal spray dryer spray of Chinese herbal extract

Centrifugal spray dryer Chinese medicine extract spray is a device that can complete drying and granulation at the same time. According to the process requirements, the pressure, flow rate, and nozzle size of the material liquid pump can be adjusted to obtain the required spherical particles in a certain size ratio. Spray dryer is a kind of continuous atmospheric pressure dryer. Spray the liquid material into a mist using special equipment, and dry it by contacting it with hot air. Used for drying some heat sensitive liquids, suspensions, and viscous liquids, as well as for drying fuels, intermediates, soap powders, and inorganic salts. Generally, it includes electric blast drying oven, vacuum drying oven, high-speed centrifugal spray dryer and sterile spray dryer.

　　Centrifugal spray dryer spray of Chinese herbal extractAfter filtering and heating, the air enters the top air distributor of the dryer, and the hot air enters the drying chamber uniformly in a spiral shape. The feed liquid passes through the high-speed centrifugal atomizer on the top of the tower body, and (rotating) spray into extremely fine mist like liquid beads, which can be dried into finished products in a very short time in parallel with hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the induced draft fan.

Centrifugal spray

Product Introduction

　　leaveHeart spray dryer Chinese medicine extract sprayIt is a widely used process in the liquid forming and drying industry

It is suitable for generating powder and granular solid products from solution, lotion, suspension and paste liquid raw materials. Therefore, spray drying is a very ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet accurate standards.

Performance Characteristics

The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95% -98% of the water can be evaporated instantly, and the drying time is only a few seconds, which is particularly suitable for drying heat sensitive materials.

The product has good uniformity, fluidity, and solubility, high purity, and good quality.

The production process is simplified and the operation control is convenient. For liquids with a moisture content of 40-60% (up to 90% for special materials), it is easy to control and manage them by drying them into powder products in one go.

　　Adapt to materials
