Baking soda drying with air dryer is very effective

The air flow dryer uses a high-speed flowing hot air stream to suspend the wet material (powder base) and dry it during the flow of the air stream. It has the characteristics of high heat transfer coefficient, large heat transfer area and short drying time. Airflow dryers have a wide range of applications in the production of various food additives. Such as baking soda, air dryer has become the most commonly used baking soda dryer.

The pulse airflow dryer is a large-scale continuous production drying equipment. The airflow dryer adopts the principle of instantaneous drying. It uses the rapid movement of the hot air to drive the wet materials and suspend the wet materials in the hot air. This strengthens the whole. The drying process increases the rate of heat and mass transfer. The material that has been dried by the airflow can be almost completely removed, and the dried material does not deteriorate. The output can be significantly improved compared with the drying of the general dryer. Achieve high economic benefits in the short term.

In the baking of baking soda, the baking soda enters the dryer through the conveyor and the heated natural air at the same time, and the two are fully mixed, and the evaporation and drying are achieved in a short time due to the large heat and mass exchange area. The dried baking soda is collected from the cyclone separator and another small portion of the fly powder bag filter is recycled. According to different users' requirements for the final water content of baking soda, we can design the specific model of the airflow dryer. If the final water needs to reach 1% or less, we use a secondary airflow dryer, which is equivalent to the two airflow dryers used in series. To maximize the final moisture of baking soda.

In addition, we briefly introduce the classification of the airflow dryer: the Q-type airflow dryer is a negative pressure operation, the material does not pass through the fan; the QG-type airflow dryer is a positive pressure operation; the material passes through the fan with a pulverizing effect; the FG-type airflow dryer It is an exhaust gas circulation type; the JG type airflow dryer is a reinforced airflow dryer which integrates flash drying and airflow drying. The fan with dispersion is especially suitable for airflow drying of heat sensitive materials. The high-speed flying-wing fan impeller can disintegrate the wet or even agglomerated material until it is dispersed, while stirring, mixing, and then flowing the material and the hot gas in parallel during the dispersion process. This type of equipment is suitable for drying filter blocks, but it is also a surface moisture material with a moisture content of ≤ 40%. If the treatment volume is large or the finished product is required to dry to less than 15%, secondary air flow drying can be used.
