Technological process of organic fertilizer processing with sheep manure

2021-12-21

In order to protect the environment that we rely on, the country has higher and higher requirements on the environmental protection of the farms. Most of the environmental pollution caused by manure composting in the farms has not met the national requirements. Now many farms choose to process manure into organic fertilizer, which not only solves the problem of fecal pollution, but also increases the additional income.

The complete set of equipment for organic fertilizer production line includes: organic fertilizer dumper, organic fertilizer mixer, organic fertilizer granulator, material grinder, cooler, dryer, drum screening machine, packaging machine, coating machine, belt conveyor, etc.
Farms process manure into organic fertilizer
Technological process of organic fertilizer processing with sheep manure
I. raw material and proportioning ratio
When the manure is mixed with crop straw, the amount of mixing depends on the moisture content of sheep manure. According to the fermentation process, the water content is required to be within 45%, that is, when the material is kneaded into a ball, water can be seen, but the water will not drip down, and the loose dough will disperse. Then, the corn flour and the strains needed were added. The reason of corn flour was that the sugar content of corn flour could be increased to promote the rapid fermentation of bacteria.
2、 Material mixing
The prepared materials are added into the material mixing machine for mixing, and the mixing is required to be uniform and transparent without leaving any raw blocks.
3、 Material fermentation
Then, the mixed materials are stacked in a fermentation tank or fermentation tank with a width of 2-6 meters and a height of 1.0 meters to 1.5 meters, and the materials are repeatedly turned over and thrown by a tipping machine and a stacking machine every other day. Generally, in the fermentation tank, the temperature will rise after 2 days, there will be no odor in 2 days, it will become fluffy and loose in 3 days, the compost will emit fragrance in 2 days, and it can be composted in 15 days.
4、 Fermentation technology
1. In the fermentation tank for 2 days, the temperature will rise to 60 ℃ - 80 ℃, which will kill bacteria and insects.
2. Eliminate the odor in the fermentation tank for the fourth day; Then on the seventh day, the material in the tank will become loose, dry and covered with white hyphae.
3. On the ninth day of fermentation in the tank, Jiu will emit a kind of fragrance, which is almost the same as that of koji.
4. After 10 days of fermentation in the tank, the materials will be fully fermented.
5. It represents the end of fermentation stage, and materials can be removed to the next process by forklift.
V. granulation and drying process
The materials moved to the crushing process by the forklift truck are crushed by the semi wet and high humidity material pulverizer, and then mixed by the mixing mixer. The particles are transported to the mechanical fertilizer granulator by the conveyor for granulation. The particles are sent to the dryer by the belt conveyor for drying and drying, and then cooled by the cooler. Then the conveyor is sent to the screening machine for screening
Vi. screening and packaging
More than 95% of the particles that meet the requirements will enter the next process, and about 5% of the particles will be transported to the pulverizer for crushing and granulation again. The qualified particles will enter the coating machine for coating. The coating can keep nutrients. After coating, the automatic packaging machine will be used for packaging. In this way, manure organic fertilizer processing and packaging, can be stored for sale.
The organic fertilizer production line is mainly suitable for the harmless utilization of livestock manure, so as to achieve resource recovery and recycling.
It belongs to green organic fertilizer, its organic matter content can reach more than 50%, it belongs to the organic matter fertilizer with rich nutrition.
In the practical application, the organic fertilizer equipment manufacturers generally require to mix and use the reasonable trace elements according to the soil conditions.
In this way, special organic fertilizer for different vegetables, fruit trees and other crops will be formed.
