Brief introduction of grain dryer

Grain dryer is continuously working equipment to process a large number of grains. Moisture content after drying could reach 10% below (moisture content is adjustable by the control system). Due to the reliable performance, high operation flexibility, wide application, high handling capacity, the grain dryer has a good drying effect for wheat, corn, rice, palm fiber residue, etc. Grain dryers could be used in food, grain, chemical, medicine industries, etc. Materials that are dried by a grain dryer are convenient to transport. Grain dryer is energy-saving and environment-protecting equipment that not only improves the utilization of waste, reduces environmental pollution, but also creates a good economic benefit and social benefit.

Grain dryer produced by us has been used widely in China and abroad. For example, in Shandong and Henan provinces, grains are dried for storage. Now our grain dryer has been sold to Malaysia, India, the Philippines, South Africa, Brazil, etc. Now our drying equipment is running normally, clients speak highly of our grain dryer.

Grain dryer manufactured by Zhengke has passed the inspection of Henan Quality Supervision Bureau, ISO9001 international quality management system certification, Europe CE certificate standard, Russian GOST certificate, etc. Meanwhile, we had applied many patents of grain dryers to the State Patent Office and were well-known in the drying equipment industry.

Features of Zhengke Grain dryer

1. High drying efficiency, good drying effect. Grain dryer is continuously working drying equipment, used “feeding at one end and discharging at the other” method for drying materials. Due to the high moisture content of corn, wheat, etc corps, we make a special design of the inside structure of the grain dryer, it has high drying efficiency. We could control and adjust the final moisture content to the client's request.

2. Energy-saving, environment-protecting, no pollution, no noise. Due to the special design of mechanical structure and electricity control, the grain dryer works at low power. Also, the grain dryer is equipped with multistage dust collecting equipment to meet the national standard of environment protection. Reduce the environmental pollution from equipment; it is a kind of good energy conservation and environmental protection equipment. Our grain dryer adopts an enclosed structure; no air pollution and noise pollution will happen during the drying process.

3. Wide application range, low request for the working environment. Zhengke grain dryer is applicable for every country in the world. We could make some adjustments according to the different situations in different countries, such as voltage, engineering design requirement, geographical conditions, etc. As to the working environment, Zhengke grain dryer could work normally in severe cold, high temperature, plateau, etc.

4. Simple installation. The grain dryer could work directly on a horizontal hardened site. In the running, no vibration happens. It is also convenient to transfer and transport the equipment.

5. Few workers, simple operation, easy maintenance. To client request, Zhengke could provide semi-automation and a total automation production line. Only regular maintenance to the instruction is needed. It is very convenient to maintain.

6. High safety. The transmission parts all adopt enclosed or semi-enclosed design to the equipment standard of security, such as transmission shaft, motor, belt pulley, etc. This ensures the safety of equipment and workers.

Working principle of grain dryer

The grain dryer is placed at an inclination of 3-5°. Grains are sent to the inlet by feeding device, then spiral feeders push materials into the drum from feeding end to discharge end. Hot air will be drawn into the drum by a draft fan and exchange heat with materials constantly. As the drum rotates, materials are lifted and scattered by lifting boards repeatedly under gravity and move toward the lower end. As grain moves forward, it gets heat directly and indirectly from the heating medium. Thus, grain gets dried and discharged at the outlet. On the inner of the cylinder, lifting boards are equipped to lift materials and scatter them. This would spread the contact surface to improve the drying rate and promote materials to move forward. Usually, a cyclone collector would collect the dust that the heating medium entrains. If you want to reduce dust content further, a baghouse or wet scrubber may be needed.
