Disc dryer
Organic fertilizer disc dryer is highly efficient and energy-saving: it adopts indirect heating method, the heat medium flows in the jacket and hollow disc, and heat exchanges with the material through the disc surface, with small heat loss and thermal efficiency of 70% - 80%. At the same time, the equipment can be optimized according to the material characteristics and drying requirements to further reduce energy consumption.
Drying evenly: the material is evenly distributed on the disc surface, fully in contact with the heating disc surface, and the organic fertilizer disc dryer allows the material to be fully turned and stirred during the drying process, avoiding local overheating or overdrying, thereby ensuring the uniformity of material drying.
High product quality: organic fertilizer disc dryer is not prone to overheating and deterioration due to the relatively low and uniform material temperature during the drying process, which can better retain the nutrients and active substances in the organic fertilizer and improve product quality.
Strong adaptability: organic fertilizer disc dryer can be applied to various types of organic fertilizer materials, including materials with high viscosity and high water content. By adjusting the number of layers, rotation speed, heating temperature and other parameters of the drying disc, the drying requirements of different materials can be met.
Easy operation: The organic fertilizer disc dryer has a high degree of automation and can realize remote control and monitoring. The operator only needs to set the drying parameters and the equipment can run automatically. At the same time, the maintenance of the equipment is also relatively convenient, reducing labor costs and labor intensity.
Good environmental performance: The organic fertilizer disc dryer adopts a closed drying system to reduce the emission of dust and exhaust gas. At the same time, the equipment is equipped with efficient dust removal and exhaust gas treatment devices to further reduce pollution to the environment.
Organic fertilizer disc dryer structure composition
It is mainly composed of drying disc, main shaft, rake arm, rake leaf, shell, heating medium system, feeding device, discharging device, etc. The drying disc is arranged horizontally in multiple layers, and the material is pushed and moved by the rake leaf on the disc surface; the main shaft drives the rake arm and rake leaf to rotate; the shell plays a sealing and heat preservation role; the heating medium system provides heat for drying; the feeding device is used for uniform feeding, and the discharging device is used to discharge the dried material.
Working principle of organic fertilizer disc dryer
The wet material enters from the feeding device and falls on the top drying plate. The main shaft drives the rake arm and rake blade to rotate, so that the material moves along the spiral trajectory to the edge of the plate surface. At the same time, the heating medium passes through the hollow drying plate and the main shaft to transfer heat to the material, so that the moisture in the material evaporates. The material falls from the edge of the upper drying plate to the lower drying plate, and the above process is repeated until it is discharged from the discharge port of the bottom drying plate.
Technical parameters of organic fertilizer disc dryer
The processing capacity varies depending on the model. Generally, it can process several tons to dozens of tons of materials per hour. The diameter of the drying plate is usually around 1-6 meters. The number of layers is generally 6-30. The spindle speed is slow, usually 1-10 rpm. The power ranges from tens of kilowatts to hundreds of kilowatts depending on the size of the equipment. The temperature of the heat medium is generally 150℃-350℃.
Application scope of organic fertilizer disc dryer
It is suitable for a variety of organic fertilizer materials, such as organic fertilizer raw materials processed from livestock and poultry manure, sludge, straw, etc., especially for materials with high viscosity and high water content. It has a better drying effect.
Organic fertilizer disc dryer supporting equipment
It is often used together with hot air furnace, feeder, crusher, mixer, granulator, screening machine and other equipment to form a complete organic fertilizer production drying line.
