Product Description

A vertical drying mixer is an integrated industrial equipment that combines material mixing and drying/dehydration functions. It is widely used in production scenarios requiring pretreatment of moist powder and granular materials, especially in the processing of recycled materials and wet-based raw materials in industries such as plastics, chemicals, and building materials. Its core advantage lies in integrating the two processes of "homogenization mixing" and "drying/dehydration" into a single device, which significantly simplifies the production process and saves space and energy consumption.

 

Application

Due to its integration and adaptability, vertical drying mixers are widely used in multiple industrial fields:
•  Plastic Industry: The most important application scenario, used for drying and dehydrating plastic recycled materials (e.g., PE, PP, PVC crushed materials), as well as mixing and drying new materials with color masterbatches, ensuring no bubbles in subsequent injection molding and extrusion processes.
•  Chemical Industry: Used for mixing and drying powder materials such as pigments, dyes, and fillers, preventing materials from absorbing moisture and caking, which could affect subsequent reactions or molding.
•  Building Materials Industry: Suitable for mixing and drying materials such as dry-mixed mortar, putty powder, and gypsum powder, controlling moisture content to ensure product strength and stability.
•  Food and Feed Industry: Used for drying and homogenizing flour, starch, and feed granules. The equipment is made of food-grade stainless steel, complying with hygiene standards.
•  Pharmaceutical Industry: Performs low-temperature gentle drying and mixing of traditional Chinese medicine powder and pharmaceutical excipients, avoiding the destruction of active ingredients by high temperatures.
 

Working Principle

The vertical drying mixer processes materials through the synergy of "mixing and turning" and "hot air drying", with the specific process as follows:
1. Feeding Stage: Moist powder or granular materials enter the vertical cylinder through the top feed inlet. The material volume is usually controlled at 60%-80% of the cylinder volume (reserving space for mixing and hot air circulation).
2. Mixing and Preheating Stage: Start the drive unit; the mixing blades rotate to drive the material to rise along the cylinder wall and fall in the center, forming a convective circulation movement to initially homogenize the material. Meanwhile, hot air generated by the hot air generator is evenly fed into the cylinder through the air distribution structure to preheat the material.
3. Drying and Deep Mixing Stage: As mixing continues, the material is fully dispersed, maximizing the contact area with hot air. Heat from the hot air is transferred to the material, evaporating moisture (or other volatile components) in the material into water vapor. The water vapor is discharged from the top exhaust port along with the rising hot air, and then vented or recovered after being treated by the dust removal device. During this stage, the material completes deep mixing while drying, ensuring the moisture content and component uniformity of the final product meet standards.
4. Discharging Stage: After reaching the set drying time, turn off the hot air device. When the material temperature drops to a safe range (or directly cools down), open the bottom discharge port. Driven by the mixing blades, the dried and homogenized material is discharged from the equipment and enters the next process.
 

Features

1.   Integrated Efficiency: Combines "mixing" and "drying" into one. Compared with separate equipment ("drying first, then mixing"), it saves more than 50% of production time and over 30% of equipment floor space, while reducing material loss and pollution during transfer.
2.   Good Drying Uniformity: The strong convection design of the mixing blades fully turns the material, and hot air penetrates the material layer evenly, avoiding problems such as "local overheating and coking" or "internal moisture retention". It is especially suitable for heat-sensitive materials (e.g., plastic particles).
3.   Low Energy Consumption: The vertical structure reduces hot air loss, and the mixing and drying share the drive system. Compared with separate equipment, energy consumption is reduced by 20%-40%. Some models can recover waste heat from exhaust gas to further save energy.
4.   Easy Operation: One-key start/stop, visual parameter adjustment. The equipment has a dead-corner-free internal design (arc-transition cylinder wall, wall-scraping blades), facilitating cleaning and maintenance and meeting the hygiene requirements of the food and pharmaceutical industries.
5.   Strong Adaptability: By replacing mixing blades and adjusting hot air temperature and speed, it can adapt to various materials such as plastic particles, resin powder, gypsum powder, feed, and traditional Chinese medicine granules. It can also handle moist materials with an initial moisture content of 5%-30%.
