The vertical mixer dryer is mainly used for mixing plastic granules of multiple colors. This equipment has two core functions: hot air drying of plastic particles; and uniform color mixing of plastic particles with functional masterbatches and fillers. It is an essential supporting equipment for injection molding machines and granulators.The vertical mixer dryer adopts the method of rotating stirring blades to turn over plastic raw materials for rapid mixing, making it one of the indispensable supporting equipments for injection molding machines and granulators.
Working Principle of Vertical Mixer Dryer:
In this machine, the rapid rotation of the screw lifts the raw materials from the bottom center of the barrel to the top, then scatters them in an umbrella - shaped manner and returns them to the bottom. In this way, the raw materials roll up and down and are stirred in the barrel, and a large amount of raw materials can be evenly mixed in a short time.Air is sent to the electric heating box by the blower, turned into hot air after heating, and then automatically controlled by the electronic temperature regulator.The hot air enters at an appropriate temperature, conducts heat exchange along the way, and continuously takes away moisture, thus achieving efficient drying of plastic materials.
Main Structure of Vertical Mixer Dryer:
- Frame part: All working parts of the machine are installed and fixed on the frame. The frame of the machine is made of high - quality carbon steel plates and channel steels through welding, which meets strict product qualification standards and specific process requirements to serve the purpose of the machine.
- Transmission connection part: The machine uses a cycloidal pinwheel reducer to drive the main shaft to rotate. The working part of the main machine adopts nylon pin as the transmission connector for gear meshing and driving transmission, which is convenient for assembly and maintenance.
- Stirring working part: The power is transmitted from the driving wheel to the main shaft through the pin coupling. It can evenly turn over the materials in the stirring chamber, ensuring sufficient mixing of the materials and thus greatly reducing the material residue.
Operation Process of Vertical Mixer Dryer:
- Material preparation: First, prepare the materials to be mixed and put them into trays respectively. The materials should be slightly moist, not completely liquid, solid or semi - solid. If the materials are too rough, they can be crushed by a crusher first before preparation for mixing.
- Feeding: Open the upper cover of the product, put the newly prepared materials into the U - shaped trough, and add a small amount of water, which should not exceed the level of submerging the pulp shaft, so as to facilitate better mixing of the materials.
- Mixing: Cover the upper cover of the trough, lock the fixing screws of the trough, then turn on the switch to start mixing the materials.
- Discharging: First turn off the switch, loosen the fixing screws of the trough, tilt the trough, and pour the materials into the tray.

Technical Features of Industrial Vertical Mixer Dryer:
- Structural Design & Working Principle: The industrial vertical mixer dryer adopts a vertical tower structure, allowing materials to form a circular flow in the vertical direction—ensuring uniform processing throughout the batch.High-speed rotating spiral blades lift materials from the bottom and scatter them back down at the top via centrifugal force, creating a continuous cycle that eliminates material buildup.Meanwhile, the heating system (either via hot air injection or jacketed heating) ensures materials are evenly heated during movement, enabling rapid moisture evaporation—boosting overall drying efficiency.
- Diversified Heating System Configurations: Our vertical mixer dryer supports multiple heating methods, including steam, heat transfer oil, hot water, or electric heating—flexible for different factory energy supply conditions.Large-scale vertical mixer dryers can also be equipped with agitator shaft and blade heating functions, further increasing heat exchange area and improving drying efficiency—suitable for high-volume production lines managed by factory directors.
- Vacuum Drying Technology: By integrating a vacuum system, our vacuum vertical mixer dryer creates a negative pressure environment inside the equipment, lowering the boiling point of liquids and enabling rapid evaporation of moisture or solvents at low temperatures—perfect for heat-sensitive materials.This feature is particularly suitable for processing heat-sensitive materials and can reduce drying time by over 40%—a significant time-saving benefit for production line scheduling.
- Anti-Adhesion and Easy-Clean Design: For viscous materials, the inner wall of the vertical mixer dryer can be coated with Teflon or made of mirror-polished stainless steel, combined with a self-cleaning scraper design to effectively prevent material adhesion—reducing maintenance workload for engineers.Meanwhile, the CIP (Clean-in-Place) online cleaning system simplifies equipment maintenance processes and meets GMP standards—critical for pharmaceutical and food industry compliance required by procurement teams.
