product Overview
  Wet material enters the spiral bed from the top feeding port. Under the action of circumferential exciting force and gravity, the material jumps from top to bottom along the spiral bed to the bottom layer; at the same time, clean hot air enters from the bottom of the spiral bed, conducts sufficient heat and mass transfer with the materials distributed on the bed, and is discharged from the top moisture discharge port. Thus, the material can achieve the purpose of drying.
product application
  This drying equipment product is mainly suitable for drying traditional Chinese medicine pills; it can also be suitable for drying granular, short strip, and spherical materials in the chemical industry, food, plastics, building materials, feed and other industries.
main features
● Hot air passes through the material layer many times and flows in reverse direction with the material, allowing sufficient heat exchange and high thermal efficiency.
● Compact structure and small floor area.
● The residence time of the material in the bed can be adjusted, making it easy to operate.
● While the material moves circularly from bottom to top along the spiral bed, it also jumps itself, thereby increasing the contact between the material and the hot air and enhancing the drying effect.
● Continuous feeding and discharging is suitable for assembly line operations and easy to reach "GMP" specifications, which can replace traditional box drying.
● There is basically no damage to the surface and shape of the material, which not only ensures the roundness of the pill, but also greatly reduces the crushing rate of the pill.
