Working Principle
The mixing dryer achieves dynamic drying through two-stage spiral rapid conveying. The first-stage spiral conveys raw materials into the barrel, while the second-stage spiral quickly lifts the raw materials to the top of the barrel, making them scatter in an umbrella-like shape. At the same time, hot air is blown around from the center of the barrel's bottom and penetrates the scattered raw materials upward. This allows the raw materials to fully contact the hot air while continuously tumbling, completing comprehensive heat exchange and realizing dynamic drying. Compared with ordinary dryers where raw materials are stationary and hot air penetration is insufficient, this design avoids local heating, agglomeration and blockage of raw materials, ensuring the drying effect.
Product Features
Diversified Functions
It can perform mixing and drying simultaneously, saving time and energy consumption. When drying is not needed, the drying switch can be turned off to use it solely as a mixer, which is suitable for mixing granular and powdery materials.
High-Quality Materials
The barrel, spiral blades, shaft, cylinder, support frame and all parts in contact with raw materials are made of stainless steel, ensuring reliable use and hygiene.
Convenient Operation
When cleaning materials, simply open the material cleaning port and let the spiral blades rotate in the reverse direction to easily complete the material cleaning operation, reducing maintenance difficulty.

Frequently Asked Questions (FAQ)
How does the mixing dryer achieve dynamic drying?
The machine utilizes a two-stage spiral rapid conveying design. The first-stage spiral moves raw materials into the barrel, and the second-stage spiral lifts them to the top to scatter in an umbrella shape. Simultaneously, hot air is blown from the bottom center, penetrating the tumbling materials for comprehensive heat exchange.
Can this equipment be used only for mixing without drying?
Yes. The drying switch can be turned off independently. This allows you to use the machine solely as a mixer, making it highly suitable for mixing both granular and powdery materials.
What materials are used to construct the contact parts of the dryer?
To ensure reliability and hygiene, all components that come into contact with raw materials—including the barrel, spiral blades, shaft, cylinder, and support frame—are constructed of high-quality stainless steel.
Is the cleaning and maintenance of the mixer complicated?
No, it is designed for convenient operation. You only need to open the material cleaning port and set the spiral blades to rotate in the reverse direction to quickly and easily clear the residual materials.
What major component brands are used in this machinery?
We cooperate with world-renowned brands to ensure stable performance. The system features a Siemens PLC, an ABB frequency converter, and Schneider air switch contactors.
What is your warranty and after-sales support policy?
We provide a 1-year free warranty, one-to-one dedicated service, and a 7*24-hour response system. Furthermore, we offer technical support (including installation guidance and remote diagnosis) as well as operation and maintenance training.
