Mixing & Drying Machine for Wet Plastics - China Suppliers & Factory for Injection Molding Production Lines

,

PRODUCT FEATURES
Traditional drying machines often fail to provide sufficient hot air penetration due to the static nature of the material during operation. This can lead to uneven heating, causing the material to clump and ultimately resulting in inadequate drying effects. Our innovative machine is designed with a two-stage spiral transport system. The first stage efficiently moves raw materials into the barrel, while the second stage quickly elevates and disperses them in an umbrella shape at the top of the barrel. This allows hot air to flow upward from the bottom, effectively penetrating the materials, ensuring dynamic drying with optimal heat exchange.
With continuously rolling material inside the barrel and a consistent flow of hot air, our machine facilitates synchronous mixing and drying, significantly reducing both time and energy costs. If drying is not necessary, you can easily switch off the drying function, enabling the machine to operate solely as a mixer. This versatility makes it ideal for blending granulated and powdered materials, perfect for various applications in different industries.
The entire construction, including the barrel body, spiral vanes, shaft, cylinder, support frame, and all components in contact with the raw materials, is made from high-quality stainless steel. This ensures durability, resistance to corrosion, and long-lasting performance, aligning with the standards expected from leading China suppliers and factory manufacturers.
Material clearing is hassle-free with the dedicated opening; simply activate the spiral vanes in reverse direction for easy and efficient removal of materials.

    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.
