(3)Flash dryer method

Another dry method is by machines. The flash dryer can dry wet starch in 2-3 seconds and can achieve high capacity processing. What’s more, the flash dryer is a negative design in that the outside pressure is lower than the inner pressure to ensure no leaking phenomenon. Then pulse tubers design can expand starch passing time to get a better drying effect. Whole drying processing is fast and has no touch with air to get high quality starch.
