Cassava Starch  XSG Flash Drying Machine (Spin Flash dryers ) (Rotating flash Dryer)( Flash cooler )

XSG Cassava Starch Spin Flash Dryer is widely used for drying materials such as paste, cake shape, powder, granules material, etc. It is a new type high drying efficiency and low energy consumption equipment that researched and developed by our company.

Hot air enters the stirring part of drying chamber from the bottom, material is stirred by stirring device and then the hot air exerts strong shearing, blowing, floating and rotating effect to material. Therefore material is crushed by centrifugal, shearing, impacting and friction effect. It strengthens the heat exchanging process. In the bottom of drying chamber, big and damp granules are crushed by stirring device, the particles with low moisture content and small size are lifted by rotary air stream, and be further dried. Gas and solid two phases rotary flow, inertia of solid phase is bigger than gas phase, the relative velocity between gas phase and solid phase is high, heat exchanging efficiency is strengthened, so the drying intensity of this machine is high.

XSG Cassava Starch Flash Dryer Application Ceramic industry: Kaolin, bentonite, clay, etc.

Foodstuff industry: Soybean protein, gelatinized starch, vinasse, triticum, wheat starch, etc.

Preface

Wet material is dispersed into a stream of heated air (or gas) which conveys it through a drying duct. Using the heat from the airstream, the material dries as it is conveyed. Product is separated using cyclones, and/or bag filters. Typically, cyclones are followed by scrubbers or bag filters for final cleaning of the exhaust gases to meet current emission requirements.

Feed system

The feed system consists of a feed vat where a discontinuous flow of product is buffered and fragmented by an agitator prior to continuous drying. A variable speed feed screw (or pump in the case of fluid feed) forwards the product to the drying chamber.

Drying chamber

The rotor at the conical base of the drying chamber fluidizes product particles in a drying-efficient hot air flow pattern in which any wet lumps are rapidly disintegrated. Hot air is supplied by a temperature-controlled air heater and speed-controlled fan, entering the drying chamber at a tangent in order to establish a turbulent, whirling air flow.

Airborne, fine particles pass through a classifier at the top of the drying chamber, while larger particles remain in the air flow for further drying and powdering.

The drying chamber is rigidly designed to withstand pressure shock in the event of explosive combustion of flammable particles. All bearings are effectively protected against dust and heat.

Bag filter

Powder from the drying chamber is collected in bag filter, while the outlet airleaves the system at the top via a suction fan.

Pneumatic coolers are a simple and reliable method of cooling and conveying dried product. In many instances ambient air will achieve the desired cooling duty. Where required, greater cooling capacity and a finer degree of control can be achieved with conditioned air at a controlled humidity and temperature.
