Air-stream crash dryer machine

Introduction of air-stream crash dryer machine:

Drying process is the last procedure for flour or starch production. Air-stream Crash Dryer manufactured by DOING adopts new technology, which apply flash vaporization drying principle to save steam consumption and prevent gelatinization.

The working sequences of Air-stream crash dryer are as follows:

(1) Wet material is fed into the drying tube by conveyor and mixed with hot air, then divided into two suspensions and moving forward with high speed. The two suspension materials collides and enters into the fan after damped vibration(one part of air-stream dryer machine). Bonded particles in wet starch get smaller after collision, vibration and fan crushing refinement, with increases specific surface area of materials so as to improve thermal efficiency, making free water vaporized quickly.

(2) Material is discharged into the vortex chamber of air-stream crash dryer machine by the fan. After crushed by agitator, material would be sent forward. Wet material with relatively high humility and large gravity rotates along the outer wall at high speed, increasing the relative speed, enhancing heat transfer effect, and improving volumetric heat transfer coefficient. As a result, qualified material with appropriate water content would be discharged from center outlet.

(3) Material discharged from vortex chamber enters the first stage cyclone, and dry starch goes into classification screen from bottom outlet, to be measured and packed. Other material with small amount light powder would enter the second stage cyclone for recycling, while wet air is discharged into atmosphere.

Performance characteristics of air-stream crash dryer machine:

Short drying time, drying time is in commonly 1 ~ 2 seconds, quality has a protective effect for the material, especially suitable for heat-sensitive materials; High thermal efficiency, the drying time is short, High output, large precipitation range; Equipment is simple, cover an area of small, investment; Hot air source: oil burner, gas type, coal-fired stove, steam heat exchanger.
