Peptide white powder spray dryer Stainless steel plant protein spray drying equipment

 Product introduction

Spray drying is a widely used process in the liquid process forming and drying industry. It is suitable for generating powdery and granular solid products from solutions, emulsions, suspensions and pasty liquid feedstocks. Therefore, spray drying is an ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the product must meet precise standards.

Working principle

The air is filtered and heated into the air distributor at the top of the dryer, and the hot air enters the drying chamber evenly in a spiral shape. The feed liquid passes through the high-speed centrifugal atomizer at the top of the tower body, (rotating) spraying into very fine mist liquid beads, which can be dried into finished products in a very short time in parallel with the hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone, and the exhaust gas is emptied by the fan.

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% to 98% of the water can be evaporated instantly, and the drying time only takes a few seconds. It is especially suitable for drying heat-sensitive materials.

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

◎ The production process is simplified and the operation and control are convenient. For liquids with a moisture content of 40-60% (up to 90% for special materials), they can be dried into powder products at one time. After drying, there is no need to crush and screen, reducing the production process and improving the purity of the product. The particle size, bulk density and moisture of the product can be adjusted by changing the operating conditions within a certain range, and the control and management are very convenient.

Note: The water evaporation amount is related to the characteristics of the material, as well as the temperature of the hot inlet air and the outlet air. When the outlet temperature is 90°C, the water evaporation curve is shown in the above figure (for model selection reference). With the continuous update of products, relevant parameters may change without prior notice.
