Overview

The vacuum spiral dryer adopts a full range of heating mode design. After the material enters the equipment, all material contact points are heated by heat source, making the material heating more uniform, without dead angles, and smoother in fluidity. A filtration system is designed above the equipment to filter the dust of the material in the later stage. The structure and working principle of the equipment determine its working efficiency. It is energy-saving, efficient, environmentally friendly, small in footprint, and highly automated. Different materials can be used according to the characteristics of different materials. It plays a key role in one-time desolventization, making the solvent content very low. The vacuum spiral dryer integrates drying, cooling, desolventization, reaction, product formation, and mixing, reducing the link of transporting materials in the production process to meet the production needs of more customers.

Principle

The vacuum spiral dryer uses an internal hollow blade structure to allow the material to fully circulate inside the box, fully increasing the material's contact with heat energy, making the dried material more uniform and without dead corners. The heat energy transfer uses hollow blades and the heat energy of the box wall. The material is wrapped in heat energy and flows, and there is almost no loss of heat energy. The overall equipment adopts a sealed working method to prevent dust and odor, and no leakage. The later condensation recovery device is used to recycle available resources and pollutants, thereby achieving pollution-free emissions. According to the material's temperature requirements, different heating media can be used: steam, hot water, and heat transfer oil. According to different materials, the feeding method can be added once or multiple times. After the drying is completed, the vacuum is discharged and the discharge is opened through the discharge valve.

Features

Sealing: The company's independently developed and produced low-speed mechanical combined sealing method is adopted, which has better sealing effect and longer service life.

Six-in-one: drying, cooling, desolventizing, reaction, product formation, and mixing.

Energy saving: The heating area of the equipment is increased, and the heat energy is fully absorbed by the material, reducing heat energy loss.

Environmental protection: The equipment operates under vacuum, and through the condensation recovery device, it can recycle and utilize resources without pollution.

High efficiency: Due to the increase in the heating area of the equipment, the efficiency is greatly improved compared with conventional drying equipment, thus saving energy consumption.
