  • Horizontal mixer: high mixing uniformity and low residue, suitable for mixing compound feed, concentrated feed, and additive premix. The specific characteristics are: the materials are fully mixed. 
  • Thereby improving the mixing uniformity; using a novel rotor structure, the minimum gap between the rotor and the shell can be adjusted to close to zero, effectively reducing the amount of material residue; the machine is equipped with a grease adding pipeline, the overall structure is more reasonable, and the appearance is beautiful. Easy to operate and maintain.

Granulation system:

  • Granulator equipment is required. The optional granulator equipment is: compound fertilizer double-roller extrusion granulator, disc granulator, flat film granulator, bio-organic fertilizer spherical granulator Machine, special granulator for organic fertilizer, drum granulator, rounding machine, special granulator for compound fertilizer, etc.;

Special granulator for organic fertilizer:

  • Chicken manure organic fertilizer granulator. This wet granulator is also called an internal rotating tooth granulator and is widely used for granulating organic fertilizer. 
  • Typical application materials: chicken manure, cow manure, charcoal, clay, kaolin, etc. It is specially used for granulating organic fermentation fertilizers from urban domestic waste such as livestock and poultry manure, compost fertilizer, green manure, sea fertilizer, cake fertilizer, peat, soil fertilizer, three wastes, microorganisms and other organic fertilizer raw materials. properties, the particles are irregular spherical particles. 
  • The qualified granulation rate of this machine is as high as 80-90%, which is suitable for a variety of different formulas. The compressive strength of organic fertilizer is higher than that of discs and drums, and the large ball rate is less than 15%. The uniformity of particle size can be passed according to user requirements.

Finished product packaging system working principle:

  • Principle of quantitative packaging scale: When the quantitative packaging scale enters the automatic operation state, the weighing control system opens the feeding door and starts feeding. 
  • The feeding device is a fast and slow two-stage feeding mode; when the material weight reaches the fast feeding set value when the material weight reaches the final set value, close the feeding door and complete the dynamic weighing process; at this time, the system detects whether the bag clamping device is in a predetermined state. 
  • When the packaging bag has been clamped After tightening, the system sends a control signal to open the discharging door of the weighing hopper, and the material enters the packaging bag. 
  • After the material is discharged, the discharging door of the weighing hopper automatically closes; after the material is discharged, the bag clamping device is released, and the packaging bag automatically falls; 
  • After the packaging bag falls, it will be sewn and transported to the next station. This cycle runs automatically.

Introduce powdered poultry organic fertilizer production double roller extrusion technology:

  • For example, the raw material is chicken manure + straw powder. First, mix the chicken manure with an appropriate amount of straw powder. The amount of mixing depends on the moisture content of the chicken manure. Generally, fermentation requires a moisture content of 45%, that is, it can be kneaded into a ball with your hands and can be seen between your fingers. Water, but not dripping, it will disperse as soon as you let go.
  • Then add cornmeal and bacteria. The function of cornmeal is to increase the sugar content for bacterial fermentation, so that the biological bacteria decomposition agent will quickly take over. Then add the prepared mixture into the mixer and mix. The mixing must be even and thorough without leaving any lumps.
  • The mixed ingredients are piled into a long strip with a width of 1.5 meters to 2 meters and a height of 0.8 meters to 1 meter, and are turned with a turning machine every 2 days. It takes 2 days to heat up, 4 days to become odorless, 7 days to become loose, 9 days to become fragrant, and 10 days to become fertilized. Specifically, on the second day of stacking, the temperature can reach 60℃-80℃, killing pests and diseases such as E. coli and insect eggs;
  • On the 4th day, the odor of chicken manure was eliminated; on the 7th day, the compost became loose and dry, covered with white mycelium; on the 9th day, it gave off a aroma of distiller’s yeast; on the 10th day, the bacterial manure was fermented and matured, and can be used after a little drying The semi-wet material is crushed by a crusher and then screened by a screening machine. The powdered organic fertilizer is ready and can be packaged and stored.
