How the turning machine turns livestock manure into high-quality fertilizer under aerobic conditions

The flipper is a kind of mechanical equipment (composition: driving device, variable speed device, etc.) developed and produced based on dynamic composting. The early composting process was static composting, which was often converted to anaerobic fermentation due to insufficient oxygen supply, which produced a large amount of sulfur. Odors such as hydrogen (chemical formula H? S), and there is a risk of blow up. Later, in the middle of the last century, the earliest German company BACKHUS (Company) developed an improved aerobic fermentation compost. The mechanical equipment that supplies oxygen and improves the shape of the material is called a dumping machine, also called a stacker.

基本 Basic indicators of organic fertilizer fermentation and maturity:
1, looseness (divergence) Biological fermentation method from the fourth day of fermentation, loose, showing a crushed shape. The organic fertilizer granulator is used to granulate various organic substances after fermentation, which breaks through the conventional organic granulation process. Without drying and pulverizing the raw materials before granulation, the pellets can be processed directly by batching, which can save a lot of energy. .
2. Odor The biological fermentation method began to reduce the odor from the second day, disappeared on the fourth day, completely disappeared on the fifth day, and the fragrance of the earth was exuded on the seventh day.
3. Temperature The biological fermentation, also known as the fermentation method, reached the high-temperature stage on the second day, and began to fall after seven days. Organic fertilizer granulator is suitable for the domestic garbage of organic manure and animal manure, manure and urine, compost fertilizer, green fertilizer, sea fertilizer, cake fertilizer, peat, soil miscellaneous fertilizer, three wastes, microorganisms, etc. The speciality of organic fermentation fertilizer granulation, the particles are irregular pellets. The qualified granulation rate of this machine is more than 80-90%, and it 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. The stepless speed regulation function of this machine is adjusted. Keep it in the high temperature stage for a long time, and the fermentation is complete.
4, PH value PH value of biological fermentation method reaches 6.5.
5. Moisture content The initial moisture content of the fermentation raw materials is 55%, and the moisture content of the biological fermentation method can be reduced to 30%.
6. Ammonium nitrogen (NH4 + -N) At the beginning of fermentation, the proportion of ammonium nitrogen in the dumping machine increased rapidly, reaching the highest amount on the fourth day, which was caused by ammoniation and mineralization of organic nitrogen. Then, the ammonium nitrogen in the compost gradually decreased due to volatilization loss and conversion to nitrate nitrogen. When the ammonium nitrogen is less than 400mg / kg, the maturity mark is reached. The ammonium nitrogen content of the biological fermentation method can be reduced to about 215 mg / kg.
虽然 Although livestock and poultry manure is a very good organic fertilizer, there are many disadvantages if undecomposed livestock and poultry manure is directly applied to farmland or simply dried to be used as organic fertilizer.
A. Pest and disease transmission: The direct use of unripe organic substances will lead to the spread of disease and insect pests, crop morbidity, and affect the health of consumers of agricultural products;
B. Fermented seedlings: After fermented raw manure is applied to the ground, fermented manure begins to ferment when fermentation conditions such as moisture are available, and the heat generated by fermentation will affect crop growth;
C. Hypoxia in soil: Organic matter consumes oxygen in the soil during decomposition, which will inhibit crop growth. Therefore, it can be safely applied after composting and maturation to achieve harmless treatment (chǔ lǐ);
D. Slow fertilizer effect: Nutrients in unfermented and decomposed organic fertilizers are mostly organic or slow-acting, and cannot be directly absorbed and utilized by crops. Only decomposed and converted into quick-acting states can be absorbed and utilized by crops;
E. Large volume: Directly applied without fermentation, also known as fermented rotten ferment, the feces are large in volume and high in water content, and are very inconvenient to transport and use. The pile turning machine uses the rotating knife shaft mounted under the rack to perform mixing, fluffing, and moving piles of fertilizer-based raw materials. After the car passes, it is tampered into new bar stacks. The machine can be used in open outdoor open fields and in workshop sheds. Therefore, it can be safely applied after composting and composting, and achieving harmless treatment.
The traditional composting method is a natural composting method, which requires no equipment (shèbèi) but has a large area, slow decay, poor quality, low efficiency, high labor intensity, and harsh surrounding environment. Modern aerobic (Oxygen) composting is a method for composting and turning equipment to make livestock and poultry manure use aerobic microorganisms to stabilize and harmless under aerobic conditions, and then convert it into organic fertilizer. Comparatively speaking, aerobic compost has the characteristics of simple process, low investment and low operating cost. It can effectively kill pathogenic microorganisms. It is an effective and economical reasonable treatment method (chǔ lǐ). It has been widely used at home and abroad. )Applications.
