How does the poultry manure compost fermentation turner work

The manufacturing of NPK fertilizer is mainly the mixing of different chemical fertilizer raw materials, and the most important step in the process of producing organic fertilizer from livestock manure is composting and fermentation. Nowadays, with the development of Industrial Science and technology, fertilizer plants often choose compost turner to replace labor.The organic fertilizer production line adopts compost turner equipment, which has larger production capacity, lower production cost and guaranteed fertilizer quality. So how do these turner machines carry out composting and fermentation?

Ground fermentation turning machine

Corn flour can be added into the fermentation products to increase sugar content for the fermentation of bacteria, so that the multi-dimensional complex enzyme bacteria quickly take the advantage. The stirred ingredients are piled into long piles with a width of 1.5m-2m and a bottom of 0.8m-1m, covered with sacks for aerobic fermentation. Then feed the mixed material into the mixer for mixing. The mixing must be even and thorough, and there is no dead block left. Then add the corn flour war fungus. As usual, 45% dew is required for fermentation, that is, the feet are pinched into a ball, and there is water between the fingers, but there is no dripping water. It can be collected as soon as you let go. The windrow turner machine regularly stirs the fermented product. This fermentation method is more suitable for individuals or small businesses. In the processing of organic fertilizer, the trough compost turning machine is more widely used.

In terms of the fermentation process, the temperature on the first day of composting can reach 60 degrees Celsius to 80 degrees Celsius, which can kill E. coli, insect eggs and other pests; the second day eliminates the smell of chicken manure; the third day compost becomes loose, dry and less Modest red mycelium; on the fourth day, a kind of koji fragrance is recovered; on the fifth day, the bacterial fertilizer will be fermented and mature, and the bag can be unpacked and shipped out of the factory after a little reduction and drying. It is heated in one day, odorless in two days, loose in three days, fragrant in four days, and fertilizer in five days. It is suitable for the bio-organic fertilizer manufacturing process, the decomposed organic fertilizer is further processed with NPK fertilizer granulator. The organic matter content of the green ecological organic fertilizer is above 45%, which is a kind of organic fertilizer with comprehensive nutrients.

Advantages of compost turning and fermentation of chicken manure

1. Start fermentation quickly. Generally in summer, the composting time for chicken manure compost treated by a professional compost turning machine to reach the harmless index is about 20 days, and it usually takes about 60 days for natural fermentation to reach this index. Mainly because of the growth and reproduction of microorganisms, the materials in the materials are fermented and degraded, shortening the time for compost to reach the high temperature stage, and prolonging the high temperature period. In winter, because the temperature is too low, it is difficult to start fermentation. You can add starter microorganisms to the chicken manure to quickly start the chicken manure fermentation. 2. Eliminate pathogenic microorganisms. In the process of adding microbial agents to treat chicken manure with an organic fertilizer turning machine, the compost temperature can reach 65℃~70℃ or even higher. The high temperature not only makes the chicken manure and other materials decompose quickly, but more importantly, it can effectively kill Inactivate pathogenic microorganisms or viruses, among which the stack temperature of 50℃~70℃, lasts for 6~7 days, to the eggs and pathogenic bacteria. It can achieve a very good lethal effect, such as avian influenza virus, which can be killed in a few minutes at a high temperature of 60℃~70℃. 3. Remove odor. Chicken manure composting fermentation can effectively remove malodorous gas. This is mainly because microorganisms can decompose non-nitrogen and sulfur-free organic substances such as phenol, carboxylic acid, formaldehyde, etc. into CO2 and H20; ammoniated nitrogen-containing organic substances into NH3, which can be oxidized by nitrosating bacteria to NO2- , And then further oxidized to N03- by nitrifying bacteria; sulfur-containing malodorous substances are decomposed by microorganisms to release H2S, and are oxidized by sulfur oxidizing bacteria to sulfuric acid, so that pollutants can be removed. 4. Increase fertilizer efficiency. Microorganisms can decompose starch, lipids, hemicellulose, protein and other easily decomposed substances in chicken manure, as well as some cellulose and a small amount of lignin. Some of them are converted into water-soluble carbon and nitrogen compounds. At the same time, some carbon and nitrogen sources used by microorganisms are gradually decomposed and released with the death of microorganisms. Therefore, it can increase the content of water-soluble carbon and nitrogen in feces. Compared with the natural fermentation of chicken manure, the various enzymes produced during composting can catalyze the rapid transformation of organic matter into humic state, and the treated compost can synthesize more humic carbon and nitrogen in the same time. The compost after fermentation can be used as raw material, mixed with other NPK fertilizers, and processed by rotary drum granulator. 5. Improve crop safety. Uric acid and NH4 + - n are the main substances that affect the normal growth of crops in chicken manure. Chicken manure composting can promote the transformation of nitrogen in compost to protein nitrogen and NH3 + - N, reduce the accumulation of NH4 + - N, and quickly eliminate or reduce the substances that cause crop growth obstacles. 6. It can be made into roughage for other animals. Crude protein accounts for 31% - 33% of the dry matter of chicken manure, and more than half of them are non protein nitrogen such as uric acid, urea, creatine and ammonia, and the crude fiber contained in chicken manure and a large amount of crude fiber in bedding grass. Therefore, chicken manure is a good feed for raising livestock, poultry and fish. However, raw chicken manure contains parasitic eggs and some toxic substances and bacteria, which can not be directly fed with raw chicken manure. Microbial agents must be added to chicken manure for high temperature fermentation treatment, so that it can be processed into non-toxic and nutritious feed by fertilizer granulator.

Organic fertilizer high temperature compost fermentation method

The initial fermentation of organic fertilizer is natural compost fermentation, which is simple in operation and low in cost. However, the fermentation speed is slow, the fertilizer efficiency is poor (can not be released completely), and the maturity is not complete. After fertilization, it is easy to have secondary fermentation, burn roots and seedlings, causing unnecessary economic losses. Gradually this kind of natural compost is abandoned by people. More and more fertilizer factories add fermentation agents into the compost. Through the modern organic fertilizer production equipment such as the turner, the fermentation materials are cut, the fertilizer maturity is improved. The fertilizer efficiency is released, and there is no secondary fermentation, to avoid burning roots and seedlings, and the pests and diseases are reduced. At present, the better method of organic fertilizer maturation is high temperature composting. The following organic fertilizer equipment manufacturers will introduce the method of high temperature composting: 1. Material ratio. 5 tons of fresh feces (preferably fresh feces, the fermentation effect of fresh feces is better than that of old feces). Add a proper amount of organic fertilizer fermentation agent. The fermentation agent should be mixed with crop straw in the proportion of 1:5, and then evenly spread into the manure pile, and mix evenly. 2. Water regulation. The water content of fermentation materials should be controlled at 50-60%. The simple judgment method is as follows: grasp the mixed fermentation materials tightly, see the watermark but do not drop water at the finger joint, and release it to the ground to disperse it. In summer, there is a little more water to prevent nitrogen from ashing. Winter should be less, so as to avoid slow heating due to poor ventilation. 3. Material stacking. It can't be too small or too short when making the compost. Too small will affect the fermentation. The height and width of the compost are 1.5-2 meters respectively, and the length is unlimited. The top of the pile shall be perforated with a wooden rod to ventilate, and it shall be deep to the bottom of the pile. In trough fermentation, put the raw materials into the fermentation trough. 4. Starting temperature. The start-up temperature should be above 15℃ (when possible, start the fermentation indoors or in a greenhouse). 5. Turn over the compost for ventilation. Pay attention to proper oxygen supply and turning over during fermentation. When the temperature rises to 60-70℃ or above, the compost turning machine shall be used to stir the compost, which generally needs to be turned over 2-3 times. The stacking temperature shall be kept between 60-80℃ and shall not exceed 80℃, so as to prevent high temperature from killing beneficial bacteria in manure. Severe piles or burnt piles can occur when it is severe. 6. Fermentation complete. Generally, the material is dark brown, the temperature begins to fall to normal temperature, and the fermentation is completed when the manure is odorless and tasteless. Composts that are properly cooked are preferably pelletize. We provide different types of granulation machine, disc granulator machine, rotary drum granulator, new type organic fertilizer granulator, etc.

What is compost Can compost improve the soil

What is compost

Compost is a kind of material that decomposes and ferments organic matter (litter, straw, mowing, cattle manure, etc.) through the action of microorganism, which can be used for soil improvement. In industrial composting, cattle manure and pig manure are usually mixed with rice husk, and the fermentation materials are cut at the windrow turner, then the compost is decomposed into organic fertilizer by microorganism.By soaking the compost in the soil, it can improve the water retention, drainage, permeability and fertilization ability, and activate the microbial compost as food. Activated microorganisms help maintain soil structure and grow healthy vegetables. The standard of using compost is 2-3kg / m2. Apply compost two weeks before sowing or sowing.

Composting humus by hand

Humus is one of plant compost. Humus soil is mainly made by decomposing and fermenting leaves. Leaves and rice bran were mixed in a ratio of 5:1, and water was added to make the moisture content of the material reach 60%. Rice bran promotes fermentation. After the compost is mixed evenly, it should be tossed once a week. It takes three to six months, depending on the temperature.It is suggested to make humus from the leaves of deciduous broad-leaved trees (beech, oak, etc.). Needles such as cedars and pine trees are difficult to break down, so they should be avoided. In addition to the above humus, composting can also be made by composting household waste. Put compost into the field soil, decomposition can be accelerated.

Industrial production of compost

Industrial production of organic fertilizer, a large number of livestock manure compost fermentation, the use of windrow turner (or tank turner) mechanized place barber ferment. The fermented compost can be processed into commercial granular fertilizer by fertilizer granulator machine. The most important thing when applying compost is to avoid using fertilizer that is not fully mature. Unfermented compost produces ammonia, an odor that attracts insects and destroys the roots of crops. The industrial processing compost, compost fermentation is sufficient, fertilizer effect is better. Compost products can also be mixed with NPK fertilizer to improve the overall fertilizer efficiency of the fertilizer products. Through NPK fertilizer production process, the compost products can be processed into organic compound fertilizer products.

How to Make Organic Fertilizer by Feces Composting

Fecal composting organic fertilizer manufacturing process is to adjust the carbon-nitrogen ratio in the manure of the livestock and poultry by turning machine, manually controlling the conditions of water, temperature, pH and the like, and treating the manure of the livestock and poultry by the fermentation of the microorganisms to produce organic fertilizer.

 I. Major organic fertilizer production equipment for composting

The composting process requires a large number of organic fertilizer processing equipment.

(1). Pre-treatment equipment: mainly include stockyard, unloading platform, feeding door, loading machinery, transport machinery and so on.

(2). Composting equipment: mainly trough compost turning machine, windrow turner machine, fermentation tank.

(3). Fertilizer granulator machine: mainly organic fertilizer granulator, rotary drum granulator, disc granulator, double roller fertilizer granulator, flat-die extrusion pelleting machine, ring-die pelleting machine.

(4). Screening and packaging equipment: mainly drum screener, fertilizer packing machine.

  II. Main Technical Parameters of composting

(1). C/N ratio: C/N balance of compost mixture is the key factor for microorganisms to achieve better biological activity. The C/N ratio of compost mixture should be kept at 25-35:1.

 (2). Humidity: Aerobic composting should generally be maintained at 40-70%.

 (3). Acidity and alkalinity: Acidity and alkalinity vary with the types of compost mixtures and different stages of composting process. Normally, they need not be regulated. If they need to be regulated, they can be regulated by adding alkaline or acidic substances to the mixture before the beginning of composting degradation.

(4). Other design parameters: Rectangular fermentation stacking composting mode, the windrow turner should be used regularly to turn the pile, so that the temperature is kept below 75℃, and the turning frequency is 2-10 days/time. The width and depth of rectangular stacks are limited only by the overturning equipment. The stacks are generally 1.2-1.8 meters deep and 1.8-3 meters wide. The height of the compost is usually 2.5-4.5 meters, and the width is usually twice the depth. Fermentation tank composting, need to build fermentation tank, fermentation tank length is unlimited.

 III. Matters needing attention in composting

(1). Composting time: Composting time varies with C/N ratio, humidity, weather conditions, type of composting operation and management, waste and additives. The composting time of well-managed strip-cutting fermentation compost in summer is generally 14-30 days.

(2). Temperature: We should pay attention to the monitoring of composting temperature. The composting temperature should exceed 55℃, so as to be conducive to microbial fermentation and kill pathogens.

(3). Humidity: Pay attention to monitoring the humidity of compost mixture periodically. Excessive or low humidity will reduce or stop the composting speed.

(4). Odor: Odor is a good indicator of composting operation stage. Decay odor may mean that compost is changed from aerobic to anaerobic.
