Working principle and characteristics of three-pass dryer

一、Overview

The three-pass drum dryer is a widely used drying equipment. It can be widely used in food, medicine, chemical industry, building materials, mining and other fields to dry materials. The dryer is composed of three return drums, gas hot air furnace and nozzle, which achieves fast, efficient and energy-saving drying effect.

二、 Working principle

The working principle of the three-pass drum dryer is that the material enters the dryer from the feed port, and the high-temperature hot air generated by the hot air furnace is sent into the drum to fully exchange heat with the material, so that the moisture in the material evaporates. At the same time, while the material is drying, due to the rotation of the three return drums, the material is constantly turned in the drum, ensuring that the material is fully heated and the drying speed is accelerated.

三、Advantages

1. Fast, efficient and energy-saving: The gas hot air furnace used in the three-pass drum dryer has low energy consumption and high thermal efficiency. It can quickly send hot air into the drum, which greatly improves the drying efficiency and saves energy.

2. Adjustable temperature and speed: The three-pass drum dryer is equipped with a temperature and speed regulator, which can be adjusted according to the drying needs of different materials to meet different drying requirements.

3. Suitable for drying a variety of materials: The dryer can adapt to different materials for drying, such as grain, chemical products, wood, etc., and has good wide applicability.

四、Summary

The three-pass drum dryer has the advantages of fast, high efficiency, and energy saving, and can be used for drying a variety of materials. The dryer is an ideal drying equipment with broad application prospects.
