What machine is used to dry organic fertilizer

News dryer780

The organic fertilizer dryer is commonly used for drying organic fertilizers, among which the drum dryer is commonly used. This type of dryer uses hot air in the drum to evaporate the moisture in organic fertilizer materials until they are dried. The following is a detailed introduction to the organic fertilizer dryer:

Structure and composition

  • The organic fertilizer dryer mainly consists of the following parts:
  • Heat source: Generate high-temperature hot air, which can use various fuels such as coal, natural gas, steam, biomass pellets, electricity, etc.
  • Feeding machine: used to feed the organic fertilizer material to be dried into the dryer.
  • Feeding machine: Feed materials into the drum.
  • Rotary drum: It has a special structural device inside, such as a plate copying device or a material lifting plate, which is used to continuously disperse materials, increase the contact area between materials and high-temperature hot air, and thus achieve rapid drying.
  • Discharge machine: used to discharge the dried organic fertilizer material from the drum.
  • Material crushing device: used to crush materials before drying to improve drying efficiency.
  • Induced draft fan: used to guide hot air to circulate inside the drum.
  • Unloader: usually located at the end of the drum, used to discharge the dried material.
  • Distribution cabinet: controls the power supply and operation of the entire dryer.

Working principle

  • The working principle of the organic fertilizer dryer is as follows:
  • The heat source device generates high-temperature flue gas, which is sent into the drum dryer and exchanged through a heat exchanger to form high-temperature hot air.
  • The material is added from the feeding end and passes through the interior of the cylinder. Hot air is attracted by the fan and enters the interior of the cylinder, fully contacting the material.
  • Under the action of special structural devices inside the drum (such as plate readers or material lifting plates), the material is continuously dispersed and evenly dispersed, fully in contact with high-temperature hot air, achieving rapid drying.
  • The organic fertilizer material that has been dried continuously advances to the other end of the dryer under the action of the inclined plate and hot air, and is discharged into the finished product through the star shaped discharge valve.

Characteristics and advantages

  • The organic fertilizer dryer has the following characteristics and advantages:
  • High drying efficiency: capable of drying livestock manure with a moisture content of up to 70%~80% to a safe storage moisture of 13% in one go.
  • Environmental protection and energy conservation: The entire process is carried out in a closed system, reducing pollution to the environment. Meanwhile, multiple heat source devices can be selected as needed to achieve flexible utilization of energy.
  • Stable operation: The equipment structure is designed reasonably, made of wear-resistant and anti-corrosion materials, and has a long service life. At the same time, it has multiple protection measures, such as overload protection, temperature protection, etc., to ensure stable operation of the equipment.
  • Easy to operate: The equipment has a high degree of automation and is easy to understand to operate. At the same time, intelligent control systems can be equipped according to user needs to achieve remote monitoring and automated control.

Application scope

Organic fertilizer dryer is widely used in agriculture, animal husbandry, animal husbandry and other fields, and can be used to dry various livestock manure such as chicken manure, cow manure, pig manure, duck manure, goose manure, as well as organic waste such as crop straw and distiller’s grains. The dried organic fertilizer material has high quality and good comprehensive utilization value, and can be sold as a culture medium, feed, or organic fertilizer.
