Product Overview:
Wet material enters the spiral bed through the top feeding opening, where, under the action of circumferential vibration force and gravity, it undergoes a jumping motion from top to bottom until it reaches the bottom layer. Meanwhile, clean hot air enters from the bottom of the spiral bed, where it undergoes sufficient heat and mass transfer with the material distributed on the bed, and is then exhausted through the top dry outlet. This process achieves the goal of drying the material.

Product Applications:
This drying equipment is primarily used for drying traditional Chinese medicine pills; it is also suitable for the drying of granular, short strip-shaped, and spherical materials in industries such as chemicals, pharmaceuticals, food, plastics, building materials, and feed.

Key Features:
● Hot air passes through the material layers multiple times in the opposite direction, ensuring thorough heat exchange and high thermal efficiency.
● Compact structure, small land occupation.
● Material stay time inside the bed is adjustable and operation is convenient.
●As the material moves in a circular motion along the spiral bed from bottom to top, it also jumps, thereby increasing the contact between the material and the hot air, enhancing the drying effect.
Continuous incoming and outgoing materials are suitable for assembly line operations and easily meet GMP standards, capable of replacing traditional box-type drying.
The material's surface and shape are virtually undamaged, ensuring the roundness of the pellets and significantly reducing their breakage rate.
