The single-layer drum dryer is mainly composed of the following parts：

1. Cylinder: This is the main part of the dryer, which is used to hold the material and dry it during the rotation process.

2. Transmission Device: Including motor, reducer, coupling, etc., to provide power for the rotation of the cylinder.

3. Feeding Device: Used to evenly feed the material to be dried into the cylinder.

4. Discharging Device: To discharge the dried material smoothly.

5. Support Device: Such as supporting wheels, rollers, etc., to support the cylinder and ensure its smooth operation.

6. Heating System: Common ones include hot air furnace, steam heat exchanger, etc., to provide the heat required for drying.

7. Induced Draft System: Including induced draft fan, air duct, etc., to discharge moisture and exhaust gas.

8. Control System: Used to control the operating parameters of the dryer, such as temperature, speed, feeding speed, etc.

1. Drum Part:

The core component of a single-layer drum dryer is the drum. The drum is generally a slightly tilted cylinder. Its tilt angle helps the material to move slowly forward in the drum as the drum rotates. The angle will be designed according to the characteristics of the material and the drying requirements, generally around 3-5 degrees. For example, when drying sand, this angle allows the sand to move smoothly from one end of the drum to the other.

The inner wall of the drum is usually equipped with a lifting plate. The lifting plate has various shapes, such as straight plate type and spiral type. Their main function is to continuously lift and drop the material during the rotation of the drum. For example, when drying grains, the lifting plate can lift the grains to a certain height and then drop them, so that the grains can be more fully exposed to the hot air, thereby improving the drying efficiency.

2. Heating System:

The heating system is the part that provides the heat required for drying.

The hot air generated by the hot air furnace or burner enters the drum directly or indirectly. The high-temperature flame generated by the burner heats the air, and the hot air enters the drum under the action of the fan to heat the material. This method has a fast heating speed, but attention should be paid to the emission and safety of combustion exhaust gas.

3. Transmission System:

The transmission system is mainly used to drive the drum to rotate. It includes components such as motor, reducer, coupling and transmission gear. The motor provides power, and the reducer converts the high-speed rotation of the motor into low-speed and high-torque power suitable for the rotation of the drum, and transmits the power to the transmission gear on the drum through the coupling, so that the drum rotates at a certain speed. For example, the speed of the drum is generally 3-8 rpm. Such a speed can ensure that the material has enough time to contact with the hot air in the drum while moving forward smoothly.

4. Ventilation System:

The ventilation system includes air inlet and air outlet. The air inlet is used to introduce fresh hot air, and the air outlet is used to discharge humid exhaust gas. The fan is a key equipment of the ventilation system, which can control the flow and flow rate of hot air.

After the hot air enters the drum from the air inlet, it fully contacts with the material, takes away the moisture in the material, and becomes humid exhaust gas and is discharged from the air outlet. The design of the ventilation system should ensure good air circulation in the drum so that the drying process can be carried out continuously and effectively.

1. Material Conveying And Tumbling:

The material enters the drum through the feeding device. The drum rotates at a certain speed driven by the transmission device. During the rotation process, the material is constantly lifted and sprinkled due to gravity to form a material curtain. This tumbling movement can make the material fully contact with the hot air, greatly improving the heat transfer efficiency.

The drum is usually equipped with a lifting plate or a copying plate, which is used to further enhance the tumbling effect of the material, so that the material is evenly distributed in the drum, and ensure that every part of the material can be fully dried.

2. Generation And Flow Of Hot Air:

The hot air furnace generates high-temperature hot air, and the hot air enters the drum from one end of the drum under the action of the induced draft fan. The temperature and flow of hot air can be adjusted according to the characteristics of the material and the drying requirements.

3. Moisture Evaporation And Drying Process:

The hot air exchanges heat with the material in the drum, transfers heat to the material, and increases the temperature of the material. The moisture in the material gradually evaporates at high temperature to form water vapor.

With the continuous flow of hot air and the tumbling of the material, the moisture continues to evaporate, and the humidity of the material gradually decreases. When the humidity of the material reaches the predetermined drying requirement, the drying process is completed.

The dried material gradually moves to the discharging end under the rotation of the drum and is discharged from the drum through the discharging device.

The single-layer drum dryer is mainly composed of a drum, a drive device, a heating system and a feeding and discharging device.

The drum is the main part, generally cylindrical, which provides space for material drying. The outer shell of the drum is usually made of metal materials such as stainless steel to ensure its firmness and corrosion resistance, and can withstand certain temperatures and pressures.

The driving device is used to rotate the drum, including components such as a motor, a reducer, and a transmission chain or gear. The motor provides power, the reducer adjusts the speed, and drives the drum to rotate at an appropriate speed through the transmission components.

The heating system is a key part of providing heat for drying. A variety of heating methods can be used, such as electric heating, steam heating, fuel (gas) heating, etc.

The feeding and discharging device includes a feed port and a discharge port. The feed port is used to transport the material to be dried into the drum, and the discharge port is used to discharge the dried material.

Drying Efficiency:

Fast drying speed: For flake, strip, granular materials with good air permeability, as well as some dehydrated filter cake-like paste materials after granulation or rod-shaped, it can quickly remove moisture to achieve the purpose of drying. For example, in the drying treatment of dehydrated vegetables, Chinese herbal medicine slices and other materials, the drying operation can be completed in a relatively short time, improving production efficiency.

High evaporation intensity: It can quickly evaporate a large amount of water per unit time and unit area, so that the moisture in the material is quickly converted into water vapor and discharged, ensuring the drying effect of the material.

Drying Effect:

Good product quality: Because its drying process is relatively gentle, for some temperature-sensitive and easily damaged materials, it can minimize the impact on material quality while ensuring the drying effect, such as maintaining the effective ingredients of Chinese herbal medicine slices and the nutritional components of dehydrated vegetables.

Uniform distribution of hot air: The unique air distribution device enables the hot air to pass through the material evenly, ensuring that all parts of the material are heated evenly, avoiding the situation of incomplete or over-drying of local parts, thereby ensuring the consistency of product quality.

Energy Utilization:

Diverse energy options: The heat source can be equipped with various energy forms such as steam, thermal oil, electricity or coal (oil) hot air furnace. Users can choose low-cost and stable energy according to actual conditions to reduce energy costs.

Energy saving through air circulation: Most of the air can be recycled, which reduces heat loss, improves energy utilization, and reduces energy consumption during the drying process.

Equipment Operation:

Adjustable parameters: Parameters such as air volume, heating temperature, material residence time and feeding speed can be adjusted to meet the drying needs of different materials. Operators can flexibly adjust the operating parameters of the equipment according to the characteristics of the material and drying requirements to achieve the best drying effect.

Stable and reliable operation: The equipment structure is relatively simple, the failure rate during operation is low, and the maintenance cost is relatively low. In addition, the equipment is equipped with automatic tensioning devices, etc., which can ensure the smooth operation of key components such as mesh belts and avoid chain drop, chain jam, deviation, etc.
