Organic fertilizer drying and cooling equipment is an important device in the production process of organic fertilizers, mainly including dryers and coolers. The following is a detailed introduction to them:

The structure of the organic fertilizer dryer mainly consists of a feed head, a discharge head, a motor drive, a drum host, and a support wheel base. The drum is driven by the main motor and transmitted to the drive shaft through a reducer. The gears on the drive shaft mesh with the large gear ring fixed on the body, causing the drum to rotate.

Working principle: Wet materials are added from the feeding end, and the hot air generated by the hot air stove enters the interior of the cylinder under the action of the fan. The lifting plate inside the drum continuously flips up the material, allowing it to come into full contact with hot air, accelerating drying and heat transfer. Under the influence of the inclination and hot air, the material is discharged from the discharge head as finished products. Features: It can operate continuously, has the characteristics of few faults, low maintenance costs, low power consumption, and high output. The lifting plate design is reasonable, the heat energy utilization rate is high, the drying is uniform, and the number of material cleaning times is small.

The structure of the organic fertilizer cooling machine is mainly composed of a rotary cylinder, a lifting plate, an induced draft fan, a cyclone dust collector, etc. The cylinder is installed at an angle, with a lifting plate inside, connected to the inlet and outlet at both ends, and equipped with supporting wheels and transmission devices on the outside.

Working principle: High temperature organic fertilizer particles enter the drum from the feed inlet, and as the drum rotates, the lifting plate flips up the material to form a uniform material curtain. At the same time, the induced draft fan sucks in ambient temperature air from the tail of the drum. The cold air comes into full contact with the material and carries away heat through convection. The moisture inside the material evaporates and is discharged with the airflow, achieving cooling and dehumidification. The low-temperature organic fertilizer is discharged from the discharge port. Features: Strong compatibility with the dryer, able to achieve seamless connection between drying and cooling. High cooling efficiency, can lower the particle temperature from around 100 ℃ to below 40 ℃, and reduce the moisture content to within 12%. The device has a compact structure, reliable performance, strong adaptability, and can also adjust the fan air volume in real time through an intelligent temperature control system, resulting in good energy-saving effects.
