Pipe dryer Introduction
Pipe dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It is mainly used for drying objects. It vaporizes the moisture in the material (generally refers to water or other volatile liquid components) by heating to obtain solid materials with specified moisture content. The purpose of drying is to meet the needs of material use or further processing. According to different operating pressures, dryer are divided into two categories: atmospheric pressure dryer and vacuum dryer.
The main functions of the pipe dryer
Removal of Moisture
This is the most basic function of a pipe dryer. It heats and evaporates the moisture from the material through hot air or other drying media, achieving the purpose of drying.
Enhancement of Production Efficiency
Pipe dryers can evaporate moisture from materials in a relatively short time, thereby improving the drying efficiency in the production process.
Energy Conservation
Dryers typically use recycled heated air, maximizing the recovery and reuse of thermal energy and reducing energy consumption.
Flexibility
Pipe dryers are suitable for a variety of different types of materials and products, and can be adjusted and optimized according to specific needs.
Quality Assurance of Products
By controlling parameters such as temperature, humidity, and wind speed during the drying process, the quality and consistency of the products can be ensured.
High Processing Capacity
New types of drum bundle dryers and other equipment have a large processing capacity, a high volume of moisture evaporation, and can dry materials with high moisture content.
Clean Working Environment
Materials are dried in a sealed chamber under negative pressure, resulting in a clean working environment with no pollution and low noise.
Compact Process Layout
Pipe dryers require few additional supporting devices, occupy a small footprint, and have a compact process layout, which can be placed within a single-story factory building, saving on civil engineering costs.
Continuous Production or Intermittent Operation
Pipe dryers can operate continuously (with a high degree of automation) or intermittently (suitable for special production processes).
The structure of the pipe dryer
Heating Unit
It provides the heat source, which can be electric, gas-fired, or steam-heated, for warming the air or other drying media.
Drying Pipe
The material is conveyed through the pipe where it comes into contact with hot air, facilitating the heat and mass transfer required for drying.
Fan
It circulates the hot air or drying medium through the drying pipe, ensuring the continuity and uniformity of the drying process.
Temperature Control System
It monitors and regulates the temperature during the drying process to ensure uniform drying and control the quality of the final product.
Humidity Control System
In some dryers, a humidity control system may be included to regulate the moisture content of the air.
Material Conveying System
Includes feeders, screw conveyors, or belt conveyors, which transport the material into the drying pipe.
Cyclone Separator or Bag Filter
Separates dust or particles from the dried material, cleaning the exhaust gases.
Cooling Section
Some drying processes may require a cooling section to reduce the temperature of the material to meet the requirements of subsequent processes.
Discharge System
Expels the dried material from the drying pipe, either by gravity or mechanical discharge.
Control System
Includes various sensors, controllers, and interfaces for automated control of the drying process, ensuring precision and repeatability of operations.
Housing and Insulation
The housing protects the internal components, while insulation reduces heat loss and improves energy efficiency.
Main advantages of pipe dryer
High Efficiency and Energy Saving
Bundle dryer efficiently evaporate moisture from materials, enhancing production efficiency. They typically utilize recirculated heated air, maximizing the recovery and reuse of thermal energy, thereby reducing energy consumption. Additionally, by selecting the appropriate configuration scheme based on different process requirements, energy cost can be significantly reduced while ensuring product quality.
Wide Application Range
Bundle dryers are suitable for the drying treatment of various bulk solid powder products, especially for production lines with small batches and multiple varieties. They can be used for drying food, pharmaceuticals, chemical products, mineral powders, paper, wood, and other materials, widely applied in various industrial fields such as food processing, pharmaceuticals, chemical industry, metallurgy, and building materials.
Easy Operation
Bundle dryers can be designed and installed in single or multiple units according to user needs, facilitating flexible use. They often feature a high degree of automation, such as automatic hopper unloading functions, timed and temperature-controlled modular control systems, enabling unattended fully automatic operation.
Product Quality Assurance
By controlling parameters such as temperature, humidity, and wind speed during the drying process, bundle dryers ensure the quality and consistency of the products.
Environmental Protection and Pollution-Free
Bundle dryers are usually made of stainless steel, meeting food hygiene standards. They provide a clean working environment with minimal pollution and low noise.
Long Service Life
The main components of bundle dryers are made of high-quality materials, durable and resistant to damage. Moreover, some new types of bundle dryers have been optimized in design to reduce the risk of weld cracking and leakage caused by torque transmission in heat exchange tubes, thus extending the service life of the equipment.
Economical and Practical
Among various drying equipment, bundle dryers have relatively low power consumption and thermal consumption, making them economical and practical.
Great Drying Flexibility
Bundle dryers can adjust the drying time according to the properties of different materials and moisture requirements, capable of drying materials with high moisture content.
Application of Pipe dryer
Pipe dryer is widely used for drying small particles of loose materials in chemical industry, light industry, agriculture, food industry, feed industry and other industries. For example, in light industry, it can dry brewer’s grain, bean dregs, grain, sawdust, Marc, sand, slag and other drugs; In chemical industry, it can dry small particles, powdered materials and inorganic minerals and other materials; In starch industry, it can dry corn germ, corn bran, corn (maize) fibre, protein powder, etc: In feed industry, it can dry bran, corn pieces, bean dregs,etc; In fish industry, it can dry fodder of fish and shrimp; In oil industry, it can dry rapeseed (not as seeds). In breeding industry, it can dryer chicken manure, pig manure, cow dung and others.
