In the process of organic fertilizer production, drying is one of the key links. The newly made organic fertilizer has a high water content, and if it is not dried in time, it is easy to caking and moldy, which affects the application effect. Fertilizer dryer machine is a commonly used drying equipment in organic fertilizer production, which can efficiently reduce moisture and improve fertilizer quality.
1. Device composition
The tumble dryer is mainly composed of a drum, a hot blast stove, a feeding and discharging device, a lifting plate, a transmission system and a induced draft fan. The roller is slightly inclined to install, and the material rolls in the roller and gradually moves forward, and is fully in contact with the hot air to accelerate the evaporation of water.
2. How it works
When the dryer is working, the hot blast stove produces high temperature air flow, and the temperature is usually controlled at 200-800 ° C. The material enters the cylinder from the feed port, and is continuously thrown up by the lifting plate as the cylinder rotates, so that it is in uniform contact with the hot air, and the water is gradually evaporated and taken away by the induced draft fan. The dried organic fertilizer is finally discharged from the discharge port. According to the different flow of hot air, it can be divided into two ways:
• Downstream drying: hot air and materials flow in the same direction, drying speed is fast, suitable for high humidity materials.
• Countercurrent drying: hot air and material flow in reverse, drying more uniform, suitable for organic fertilizer with strict moisture requirements.
3. Advantages of tumble dryer
• High drying efficiency: the roller is constantly rotating, the material is heated evenly, and the drying speed is fast.
• Large processing capacity: suitable for large-scale organic fertilizer production, continuous operation, improve production efficiency.
• Energy saving and environmental protection: optimize hot air utilization, reduce energy consumption, while supporting dust removal equipment, reduce pollution.
Fertilizer dryer machine is an important equipment of organic fertilizer production line, which can efficiently remove water and improve the quality of organic fertilizer. With the improvement of agricultural environmental protection requirements, energy-saving and efficient drying technology will play a greater role in the organic fertilizer industry.
