Food Milk Powder Pilot Scale Centrifugal Spray Dryer Gas Fired Heating

Automatic 304SS/316SS Milk Powder Centrifugal

Main Introduction

High speed centrifugal spray dryer is used to make powder granule from liquid directly. It is suitable for powder production from the materials such as solution, emulsion, liquid and paste with fast drying speed, high efficiency, simplified process, and economized man resources. especially for heat-sensitive material, this technology could keep the color, spice and flavor. The final product owns good uniformity, mobility and dissolving capacity, also high purity. This machine is favorable for improving productivity and benefits well from technology, which has great perspective in chemical, light industry, construction material, foodstuff, pharmaceutical, biochemical and other industries.
