Mixing & Drying Machine: Handles wet plastic, suitable for injection molding production lines

PROPERTIES
1. When the normal drying machine is working, since the material is still, hot wind penetration is insufficient, the material is partially heated. The material will agglomerate easily and result in jams and blocks, so completed dry effect cannot be reached. The design of this machine includes two stages of spiral rapid transports. The first stage is to move the raw material to the barrel. The second stage is to rapidly lift the material to the top of the barrel and scatter it in shape of umbrella. Hot wind will blow around from the center of the bottom of the barrel. Hot wind will blow upwards and penetrate the raw material, dynamic drying with complete heat exchange is conducted.​
2. Since the raw material in the barrel is continuously rolling, hot wind is continuously blowing from the center, so mixing and drying is synchronously conducted, so it saves time and power. If drying is not needed, dry switch can be turned off, then the machine has only function of mixing. This machine can also be used for mixing of granulate material and powder material.​
3. The barrel body, spiral vanes, shaft, cylinder, support frame and the parts which touch the raw material are all made of stainless steel.​
4. When the material need clearing, open the material clearing opening and let the spiral vanes rotate in counter direction. Material clearing can therefore be simply operated.

    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.
