grain - Model 500 type -Rotary Dryer

The working principle of a drum grain dryer is to add wet materials into the drum, and under the rolling of the drum and the action of hot air, the materials come into full contact with hot air for heat exchange and mass transfer. The material is repeatedly picked up and scattered in the drum, forming a uniform curtain that comes into full contact with hot air, gradually drying the moisture in the material. As the drying process progresses, the material gradually moves from the feeding end to the discharging end, and finally the dried material is discharged from the discharging end.

The drum grain dryer is mainly composed of a drum, a hot air system, a feeding end, a discharging end, a transmission device, a support device, and a control system.
Drum: As the core component, the drum is usually made of stainless steel or other high-temperature and corrosion-resistant materials, with a cylindrical interior and surface design with small holes or special structures to promote the circulation of hot air and uniform drying of materials. The rotation of the drum is driven by a motor and achieved through a reducer and a transmission shaft.
Hot air system: composed of a hot air stove, fan, hot air duct, etc., responsible for generating high-temperature hot air and sending it into the drum to provide necessary heat energy for the drying process.
Feed end and discharge end: The feed end is usually a funnel-shaped structure used to feed grains into the drum; The discharge end is located at the other end of the drum, used to discharge the dried grains. Both ends may be equipped with devices such as valves and vibrators to control the feeding and discharging speed of grain.
Transmission device and support device: The transmission device includes a motor, a reducer, etc., used to drive the rotation of the drum; Supporting devices such as support frames, tugboats, etc. are used to support the weight of the drum and the entire equipment, and ensure the stable operation of the equipment.
Control system: composed of electrical control cabinet, touch screen, sensors, etc., used to achieve precise control of the drying process, including setting and adjusting parameters such as temperature, humidity, time, etc. The control system also has functions such as automation and intelligence, which can improve the operational efficiency and service life of the equipment.

Features and advantages:
1. Efficient and energy-saving: The drum grain dryer adopts advanced heating and exhaust technology, which can maximize energy savings and reduce production costs.
2. Good drying effect: The design inside the drum allows the grains to be fully exposed to hot air, achieving uniform drying and avoiding problems of local overheating or insufficient drying.
3. Wide applicability: The drum grain dryer is suitable for drying various grain crops and has a wide range of applicability.
4. Easy to operate: The equipment adopts an automated control system, which is easy and fast to operate, reducing the intensity of manual labor.
5. Environmental protection and energy conservation: The design of components such as hot air stoves and fans effectively treats the exhaust gas generated during the drying process, reducing environmental pollution.
