The production steps and main features of rotary flash dryer


Jiangsu Shengman Drying Equipment Engineering Co., Ltd. Rotary flash dryer has been applied to chemical, food, medicine, building materials, feed and other industries, the domestic production of rotary flash dryer manufacturers are more, but most of the same products, and in recent years To technological progress is slow.

Rotary flash dryer operation steps are as follows:

Preparatory work: first check the flash dryer two fans (induced draft fan and blower), hand rotation case of any abnormalities, if abnormal, should immediately repair. And then turn the rotation should be able to turn, and open the door to see, do not block material, into the air slot flow, all normal for the next step. If you open the door to find the mixing room blocking material, should be clean and keep the wind tank open before the next step.

Boot: first open the flash dryer fan, the motor power is large and take the star, triangular conversion start, a long time, so pay attention to the ammeter instructions, when the current drop before the next step in the operation, or because the bus current is too large And will fail. Then start the blower, when the current drops after the start mixing, feeding, off the fan and other equipment.

Feed: first open the compressed air valve and open the pulse power switch, open the steam valve, control the inlet temperature to the appropriate range, then open the inverter start button, open the inverter feeder, and then continue to add to the hopper into the baking Material can be. In the process of drying the material should always pay attention to the inlet and the mixing chamber temperature instructions, the inlet temperature and steam pipe network pressure, should always be adjusted in the appropriate range. The temperature of the mixing chamber is related to the wet and dry weight of the material and the feed rate. It is also necessary to adjust the feed rate to keep the temperature of the mixing chamber within the specified range. In the process of drying, should always pay attention to the fan out of the material outlet should be normal, if the material stopped, the application of wood hammer percussion material to fall, if not out of the material, it should be shut down, open the fan will be pound under.

Stop: after the end of the drying material, should be closed feed, off the steam so that the machine air blown about 10 minutes, blowing the machine more than expected, and the machine temperature drop before stopping, stop the flash dryer in the reverse direction Can be done. After the shutdown, the material in the trap should be cleaned before leaving.

Rotary flash dryer Main features:

1, a variety of feeding device for the choice of continuous feeding stability, the process does not produce the phenomenon of bridging.

2, the bottom of the dryer set a special cooling device, to avoid the material in the bottom of the high temperature area deterioration phenomenon.

3, a special air pressure seal and bearing cooling device, effectively extending the life of the transmission part.

4, a special sub-wind device, reducing the resistance of the device, and effectively provide the dryer air flow.

5, the drying room with grading ring and swirl pieces, material fineness and final moisture adjustable. (Such as calcium carbonate final moisture regulator to ≤ 0.1%)

6, relative to other drying methods, can effectively increase the proportion of material.

7, dry indoor gas velocity is high, the material retention time is short, effectively prevent the material sticky barrier and heat-sensitive material deterioration phenomenon, to achieve efficient, fast, small equipment, large production.

8, hot air from the inlet tube at the appropriate jet speed from the bottom of the dryer into the mixing crushing drying room, the material produced a strong shear, blowing, rotating, so the material subject to centrifugal, shear, collision, friction and dividend Micronized, enhanced mass transfer heat transfer. At the bottom of the dryer, the larger and heavier particles are mechanically broken under the action of a stirrer, the moisture content is low, the particles with smaller particle size are entrained by the rotating air stream and are further dried during the ascending process. As the gas-solid two-phase rotation flow, solid-phase inertia is greater than the gas phase, solid-gas two-phase relative speed between the larger, strengthen the two-phase mass transfer heat transfer, so the machine production strength.
