Wet materials enter the spiral bed from the top feeding port, and under the action of circumferential excitation force and gravity, the materials jump along the spiral bed from top to bottom until reaching the bottom layer; At the same time, clean hot air enters from the bottom of the spiral bed, undergoes sufficient heat and mass transfer with the materials distributed on the bed, and is discharged through the top dehumidification outlet. Thus achieving the purpose of drying the material.
This drying equipment product is mainly suitable for drying traditional Chinese medicine pills; It can also be applied to the drying of granular, short strip, and spherical materials in industries such as chemical, constraint, food, plastic, building materials, and feed.
main features
Hot air passes through the material layer multiple times and flows in reverse with the material, ensuring sufficient heat exchange and high thermal efficiency.
● Compact structure and small footprint.
The retention time of materials in the bed can be adjusted, making it easy to operate.
While the material moves in a circular motion from bottom to top along the spiral bed, it also jumps, thereby increasing the contact between the material and the hot air and enhancing the drying effect.
Continuous feeding and discharging are suitable for assembly line operation and can easily meet "GMP" standards, 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 breakage rate of the pill.
