How to Make Animal Manure into Fertilizer by Organic Fertilizer Granulator

by organic fertilizer production line

Taking into account the use of efficient fertilizers and chemical pesticides, the continuous decline of organic content in soil, and the bleak situation of soil sales, crop yield, and low quality, the entire engineering and technical personnel and experts and professors of the Academy of Agricultural Sciences have developed a bio fertilizer granulator with chicken manure, pig manure, humic acid, and wastes with high organic content as the main raw materials through repeated tests, making contributions to the healthy development of agriculture.

1: Fermentation. The main function of the fermentation part of the organic fertilizer production line is to reduce the water content in the organic fertilizer raw materials at an early stage. The raw materials of organic fertilizers are mainly chicken manure, pig manure, sheep manure and other animal manure, cow manure and sheep manure, but the humidity of chicken manure and pig manure is too high. In particular, the initial humidity of chicken manure and pig manure is generally above. It is impossible to handle such high humidity in person. It must go through the fermentation tank. Generally, the humidity of fresh chicken manure can be reduced to below by fermenting for about a week. In addition, during the fermentation of chicken manure, crude fiber materials such as bran and bran are mixed together, which tells you the key to shorten the fermentation time and reduce the cost.

2: Broken part. The feces of fermented animals are gathered together, and the massive materials are not directly dried, so it is better to use a small crusher to crush them first, and then enter the next stage. In organic fertilizer equipment, the crushing part is often essential.

3: Drying part. Here, some friends will ask how to dry again instead of fermenting. Otherwise, the fermentation can only adjust the humidity. In fact, to make organic particles, water must be below, so the drying process is also necessary.

4: Granular part. Organic fertilizer granulator is the key link of the whole organic fertilizer production line. In general, it is recommended to use the combination of pelletizer ball shaping machine for particle function, rather than traditional pelletizer ball shaping machine. The advantages of this method are high particle forming rate and good density.

5: Cooling, packaging and linking. Cooling and packaging can be ignored by a small number of production users. Users with small amount of production can dry by themselves, and only need to pack bags manually. The automatic packing machine only needs a large number of organic fertilizer production lines. The fertilizer produced by organic fertilizer equipment is an ideal fertilizer for saving agricultural production investment, improving soil fertility, increasing yield, optimizing crop quality and promoting green food and green agriculture.

How to use organic fertilizer composter reasonably and efficiently

by organic fertilizer production line

In organic fertilizer fermentation, livestock manure and other materials, domestic waste, sludge and other fertilizer making base materials should be piled on the flat ground in a choppy manner. When the tank turning machine is used to ferment organic fertilizer, the material is directly put into the fermentation tank. In the fermentation process, compost turning function is used to provide the quality of organic manure fermentation.

Organic fertilizer raw material processing and fermentation skills

(1) Ferment with weeds and crop straws (it will decompose in about 25 days):
Use crushed weeds and crop straws (generally 3-5 cm in length), which can be adjusted with 40% manure or biogas slurry; 2% urea (46% nitrogen) or equal nitrogen fertilizer can also be used Compound fertilizer can be adjusted; it can also be adjusted by adding fresh livestock and poultry manure at a weight ratio of 3:1-4:1. The decomposed compost is processed by the rotary drum granulator to produce different kinds of compound fertilizers.
(2) Fermentation with pure feces (it will decompose in about 20 days):
Mixing is to fully mix livestock and poultry manure with high moisture content with auxiliary materials and high-temperature biological fermentation bacteria in a certain proportion to reach fermentation conditions. Organic wastes such as livestock manure can be fermented directly. The purpose of mixing is to achieve high-temperature aerobic fermentation conditions through mixing, and to make the materials have good permeability. The high-temperature aerobic trough compost turning machine has a good effect on the treatment of organic fertilizer, and all the raw materials are mixed evenly during the fermentation process.
(3) Fermentation with manure (it will decompose in about 15 days):
After expanding the volume of bacteria directly, remove a layer in the enclosure evenly, stir it, and stack it directly on the fermentation tank. Repeat the operation. If the water content is too large, add appropriate amount of broken dry auxiliary materials into the enclosure to adjust. The decomposed compost is further processed with an organic fertilizer granulator machine.

Benefits of processing organic fertilizer with fertilizer by bio fertilizer granulator

by organic fertilizer production line

At present, the actual utilization rate of chemical fertilizer in China is only 30% – 45%, even lower in some regions! After the application of organic fertilizer, the beneficial biological activity improves the soil structure, increases the soil water and fertilizer conservation capacity, thus reducing nutrient loss, and increasing the effective utilization rate of chemical fertilizer to more than 50%. It can also reduce the amount of chemical fertilizer and the cost of fertilization. Since the 1970s and 1980s, the UK, France and Japan have reduced the use of pesticides and fertilizers. Organic fertilizer is the main fertilizer. The use of chemical fertilizers and pesticides has been greatly reduced. The grain output has increased and the quality is much better than before. Therefore, the fertilization method of “giving priority to organic fertilizer, supplemented by chemical fertilizer” is a reasonable fertilization method at present!

Five benefits of the combination of organic fertilizer and chemical fertilizer produced by biological fertilizer granulator! Benefit 1: The fertilizer has high nutrient content and fast fertilizer effect, but its duration is short and the nutrient is single. Organic fertilizer is just the opposite. The mixed use of organic fertilizer and chemical fertilizer can complement each other and meet the nutrient demand of crops in each growth period.

Benefit 2: After chemical fertilizer is applied to the soil, some nutrients are absorbed or fixed by the soil, reducing the availability of nutrients. After mixed application with farmyard manure, it can reduce the contact surface between fertilizer and soil, reduce the possibility of fertilizer being fixed by soil, and improve the availability of nutrients.

Benefit 3: Generally speaking, the solubility of chemical fertilizer is large, which will produce high osmotic pressure on the soil after application, affect the absorption of nutrients and water by crops, and increase the chances of nutrient loss. If it is mixed with organic fertilizer, it can avoid the disadvantage that crops absorb nutrients and water.

Benefit 4: If acid fertilizer is only applied to alkaline soil, after ammonium is absorbed by plants, the remaining acid root will combine with hydrogen ions in the soil to produce acid, which will lead to acid enhancement and soil hardening. If mixed with organic fertilizer, it can enhance the buffer capacity of the soil, effectively regulate the pH and prevent the increase of soil acidity.

Benefit 5: Since organic fertilizer is the energy source of microbial life, chemical fertilizer is the inorganic nutrition for microbial growth and development. The two mix the vitality of microorganisms to further decompose organic fertilizers. The activity of soil microorganisms can also produce vitamins, biotin, niacin, etc. Increase soil nutrients, improve soil vitality and crop growth.
