Starch drying machinery

Working principle of starch drying machinery:

Starch drying machinery is also known as starch flash dryer which is suitable for drying various of starch. The hot air tangentially enters the bottom of the starch drying machinery and is driven by the agitator to form a powerful rotating wind field. The block material enters the dryer by the screw feeder. Under the strong action of the high-speed rotating, the material is dispersed by the impact and friction force. The block material is rapidly pulverized, fully contacted with hot air and heated, dried by starch drying machinery. The dried material after dehydration rises with the hot air flow, and is recovered by the cyclone separator and the dust remover. The undried or bulk material is subjected to centrifugal force to the wall of the vessel, and is again pulverized and dried by falling to the bottom of starch drying machinery.

Starch drying machinery performance characteristics:

1. Large drying strength, low energy consumption and high thermal efficiency.

2. Compact structure, small size, high production efficiency, continuous production, thus realize "small equipment, large production".

3. Starch drying machinery combines swirling, pulverizing and drying techniques into one which is high efficient and good effect.

4. Negative pressure or micro-negative pressure operation, good airtightness, high efficiency and elimination of environmental pollution.

5. The material has a short residence time in starch drying machinery and good finished product quality, which can be used for drying heat sensitive materials.
