Temperature. The suitable starting temperature for fermentation should be 25℃~35℃. When the temperature of pig dung get this range, you can use the manure compsot turner to ferment the pig dung. If fermenting in winter, it is recommended to do it indoors or in a greenhouse. If it is outdoors, try to cover it with plastic film for fermentation.
Proportion. mix 200g-300g of pig dung starter and 20kg-30kg of bran powder thoroughly.
Moisture. Add the above mixture to 1 ton of organic fertilizer, and mix it again evenly (you can mix in small piles and then mix the small piles together) According to the mixing situation, add water or materials appropriately to control the water star at 40%-45%. The standard is to grasp it tightly with your hands, so that the moisture does not leak out.
Material stacking gauge touch. The process of fermentation raw materials are directly piled on the ground. The fermentation pile should not be too small. The piles with a height of 1.5 meters to 2 meters, a width of 2 meters and a length of 2 to 4 meters are better for fermentation. The top can be covered with plastic cloth, etc., without sealing, for fermentation. During the fermentation process, it should be turned over and stirred at an appropriate time, and water should be added or reduced according to the temperature, usually twice.
Color. When the material no longer heats up and becomes loose and dark brown, the pig dung is completely fermented.
Movable compost turner for manure composting production.
After the pig manure is drunk by the organic fertilizer starter, the fertilizer efficiency is better, the use is safer and more convenient, and the utilization rate of chemical fertilizer can also be improved. Organic fertilizer starter can not only ferment pig manure organic fertilizer, but also ferment chicken manure, sheep manure, cow manure and other livestock and poultry manure into organic fertilizer. The fermentation method is basically the same.

The pig manure from the pig farm contains 15% organic matter, the total nutrient content is not high, nitrogen 0.5~0.6%, phosphorus 0.45~0.5%, potassium 0.35~0.45% (specifically subject to local pig manure testing results). Pig manure has a finer texture and a more complex composition. It contains protein, fat, organic acids, cellulose, hemicellulose and inorganic salts. Pig dung contains more nitrogen and has a small carbon-to-nitrogen ratio (14:1). It is generally easily decomposed by microorganisms and releases nutrients that can be absorbed and utilized by crops. It is a good farm manure and a high-quality fertilizer for fertilizing and improving soil. However, most pig farms use water to flush the manure to clean the manure, which makes the production of pig manure accompanied by a large amount of sewage. Therefore, it is necessary to separate the solid and liquid, and the manure can be composted. The manure is fermented, and the aerobic and anaerobic microorganisms contained in the external bacterial agent are used to decompose the organic matter in the pig manure that is not easy to be directly used by the crop into small molecular substances. In other words, the pig manure organic fertilizer production line uses fresh pig manure as raw material and undergoes a series of processing to produce a complete set of production equipment for natural organic pig manure fertilizer. Processing pig manure organic fertilizer requires two steps: the pre-fermentation and treatment part and the further processing and granulation part.
Complete pig manure disposal system for pig farms.
The main substance in pig manure organic fertilizer is organic matter, and pig manure organic fertilizer increases the organic matter content in the soil. Organic matter can improve soil physical, chemical and biological properties and cultivate soil fertility.
The conversion of pig dung into organic fertilizer and microorganisms decompose and convert many organic matter into organic colloids, which greatly increases the ability of the soil to adsorb on the surface. It also produces a lot of sticky substances, which makes the soil particles cemented into a stable aggregate structure, which improves the soil water retention, fertilizer retention, and air permeability performance, as well as the ability to regulate soil temperature.
Pig manure organic fertilizer can also make the microorganisms in the soil multiply, especially many beneficial microorganisms, such as nitrogen-fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, nitrifying bacteria, etc. Pig manure organic fertilizer contains various active enzymes secreted by the digestive tract of animals and various enzymes produced by microorganisms. After these substances are applied to the soil, the enzyme activity of the soil can be greatly improved.
Making more organic fertilizer from pig manure can improve soil activity and biological reproduction and transformation capacity, thereby improving soil absorption, buffering and stress resistance. Process flow of pig manure organic fertilizer production line:
Pre-fermentation part: It is necessary to build a 3m wide x 50m long fermentation tank that can ferment more than 200 tons of raw materials), or one machine with multiple tanks, and then pile the raw materials (feces, biogas residue, straw and) in the fermentation tank, 1 One kilogram of composting agent is mixed with 20 kilograms of water and mixed in the raw material pile. 1 kilogram of composting agent can ferment 1 ton of raw materials. According to the comparison of raw materials, the fermentation cycle is 7-10 days at a temperature of 70C°.
The organic fertilizer raw materials are fermented and decomposed and crushed by a semi-wet material pulverizer, and then screened through a drum screen. The coarse materials are screened out and then fermented. The fine materials can be granulated, the appearance of the particles is more beautiful, and the granulation rate is higher.
The fermented materials (moisture content at 35%) are blended by a mixer, then passed through an organic fertilizer granulator, then dried by an organic fertilizer dryer, cooled by a cooler, and screened by a drum sieving machine. Back to the mixer, the qualified product can be coated with calcium, magnesium, sulfur and other trace elements in the coating machine by the powder machine, and can be passed through the silo and packaging machine.
What are the common equipment for granular organic fertilizer production line?
Organic fertilizer equipment classification:
1. Crushing equipment
The new type semi–wet material crusher-vertical crusher and horizontal crusher, the internal structure has chain type and hammer type. There is no screen, even if the material is smashed out of the water, it will not be blocked.
2. Mixing equipment
Mixing mixers–including vertical mixers, horizontal mixers, dual-shaft powerful mixers, drum mixers, etc. The internal stirring structure is divided into stirring knife type, spiral type, etc. Design a suitable mixing structure according to the characteristics of the material. The discharge port is designed for cylinder control and baffle control.
3. Conveying equipment
Belt conveyors–mobile belt conveyors, fixed belt conveyors, etc., belt conveyors are economical logistics conveying equipment that is indispensable for forming a rhythmic flow line. It has strong conveying capacity, long conveying distance and simple structure. It is easy to maintain and can easily implement many features of programmed control and automatic operation.
4. Granulation equipment
Special granulator for organic fertilizer-including disc granulator, new wet granulator, round thrower, drum granulator, roller granulator, etc. According to the characteristics of raw materials, select the appropriate granulator.
5. Drying and cooling equipment
Rotary dryer-alias drum dryer, biological organic fertilizer dryer, because the temperature of organic fertilizer can not exceed 80 ° when drying, so the dryer adopts hot air drying mode.
Cooler—similar in appearance to dryer, but with different material and performance.
7. coating equipment
Particle Coating Machine–The appearance of the main machine is similar to that of the dryer and the cooler, but the internal structure is quite different. Stainless steel plate or polypropylene lining is used inside the coating machine. The whole machine includes matching powder machine and oil pump.
8. Automatic packaging equipment
Automatic weighing and packaging machine-including spiral type and DC type, single head and double head, made of stainless steel and carbon steel, customized according to the actual needs of customers.
