Application of organic fertilizer is the key to maintain and improve soil fertility. It is also an important measure to achieve sustainable agricultural development and the recycling of various nutrients. Organic fertilizer plays an important role in balancing crop nutrient supply, improving product quality and increasing crop yield.
Raw material of organic fertilizer
1.Animal manure
Pig dung, cow dung, horse dung, sheep dung, rabbit dung, poultry dung, silkworm sand, seabird dung.
2.Straw and other plant residues
Straw, Rice Straw, Corn Straw, Bean Straw, Rape Straw, etc. They contain high levels of cellulose and lignin, which are generally used to increase the organic matter of fermentation materials and regulate the C/N ratio.
3.Cake fertilizer, mushroom dregs or furfural dregs
Cake fertilizer is the residue of oil extracted from oily seeds, also known as oil cake. It is rich in nutrients, mainly soybean cake, vegetable cake, peanut cake,tea cake, cypress cake and so on.
Mushroom dregs, it refers to the residual culture medium after the harvest of edible fungi, which is mainly composed of culture medium and residual mycelium.
Furfural dregs is the residue discharged from corn cob stalk after crushing and adding a certain amount of dilute sulfuric acid under a certain temperature and pressure, which undergoes a series of hydrolytic chemical reactions to extract furfural.
4.Silt in rivers, ponds, ditches and lakes
5.Peats and humic acids
6.Seaweed, etc.
Organic fertilizer treatment
1. The raw materials are stacked in strips according to the need. The length of strips is unlimited. When stacking in strips, the materials need to be stacked layer by layer evenly.
2. Adding microbial agents in proportion and sprinkling them on the surface of the stack according to the number of stacks.
3. Stirring fermentation, stirring the batch evenly with a tuner machine. After the temperature rises above 60 degrees, the batch is turned over every 4-5 days. After 15 days of fermentation above 60 degrees, the batch can be collected.
Selection of different types of turning machine according to site.
The compost machine without steering wheel, the driver only needs to control two bars, turning it to the left or right, and braking about 180 degrees. Hydraulic balance of steering wheel.
It can be used together with the moving machine to realize the function of many of slots for one machine. Its fermented trough can be continuously discharged or batch discharge, high efficiency, smooth operation, strong and durable, and even throwing.
This machine suit for large-scale overthrow, economies of scale. It is the main product of the development trend of the compost industry
4. Screening process. After the material is fermented according to the above steps, it will become pure organic fertilizer after screening and deep processing.
The screen machine is to screen the un-fermentation material and let the un-fermentation material fermentation again. It has the advantages of low vibration, low noise and convenient screen change.
5. Granulation, the fermented pure organic fertilizer for granulation. Choose granulator according to different raw materials.
It is used for making granulation of organic matter after fermentation, is the newest technology products by our years of research experience. The granulator has the feature of easy operation, maintenance, low power consumption, and long service life.
Make materials to ball shape granules, could add water or steam in the machine.
Flat die granulator machine has better granulation effect on fertilizers containing more straw. It can direct burdening to work out cylindrical grain, can save a lot of energy.
6. Drying, Cooling and Packaging
The moisture content of newly-made granules is relatively large, so it is necessary to dry the water below 20% of the organic fertilizer standard, and pack the dried granular organic fertilizer directly after cooling by the cooler.
Drum Fertilizer Dryer
The drum dryer is mainly used to produce fertilizer with a certain temperature and granularity. On the other hand, it also can be used for drying other materials.
After drying, the granules temperature is high, can't packing in bags. Under the action of the cooling fan, the dry air enters from the lower part of the cooler and exchanges sufficiently with the wet and hot particles from the upper tribe and the lower tribe. The temperature of the particles is cooled
Packing final products in bags, with a storage hopper above the packing machine, with scale could setting weight of bags, contain sewing machine and conveyor.
