Foreword: Changzhou Hengcheng Dry Granulation Equipment Co., Ltd. is a professional manufacturer engaged in the research, development and manufacture of drying equipment and granulating machinery. It is currently an enterprise producing more varieties of dry equipment and more complete specifications. The company absorbs advanced technology and experience at home and abroad, strictly in accordance with the requirements of national GMP design, development, production, installation and service, and strictly in accordance with the ISO9001 international quality system standards to ensure product quality. In the development and research of drying equipment, we constantly innovate and transform, and design and manufacture a series of advanced and energy-saving products.
The working principle of the air dryer :
The wet material enters the dryer through the conveyor and the heated natural air at the same time, and the two are fully mixed. Due to the large heat and mass exchange area, the evaporative drying is achieved in a short time.
The dried product is discharged from the cyclone, and a small portion of the fly powder is recycled by a cyclone or bag filter. The Q-type airflow dryer is operated under negative pressure, the material does not pass through the fan; the QG-type airflow dryer is operated by positive pressure; the material is pulverized by the fan; the FG-type airflow dryer is exhaust-circulating; the JG-type airflow dryer is fortified A type of airflow dryer that combines flash drying with airflow drying.
Dispersing fan, 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. When the material contains more than 40% moisture.
However, when ≤60%, the feeding is more difficult, and the mixer should be used to reduce the feed water by mixing the dry material. At this time, the total output of the drying equipment has a large drop, which is economical. The above is not equal. Therefore, the user should first reduce the feed moisture by mechanical means (centrifugal dewatering or pressure filtration) to ensure the smooth operation of the drying operation.
