As a new type of machinery, the organic fertilizer composter is still unknown in the national product catalogue, but it has rapidly multiplied in the fertilizer machinery and equipment family, becoming a tool to replace the manual and forklift tipping, and is the mainstream product affecting the development trend of the compost industry. Organic fertilizer composter is the core equipment of aerobic dynamic composting, and its importance stems from its role in composting production:

1. Mixing effect in raw material conditioning

In order to adjust the C/N ratio, pH and water content of raw materials, some auxiliary materials must be added into the compost. The main raw materials and various auxiliary materials are roughly stacked together in proportion, and can be mixed evenly through the stacker to achieve the purpose of tempering.

2. Adjust the temperature of raw material pile

During the operation of the organic fertilizer composter, the raw material particles are fully mixed with the air, so that a large amount of fresh air can be stored in the material pile, which is conducive to the active generation of fermentation heat by aerobic microorganisms and the increase of the pile temperature; When the temperature is high, adding fresh air can reduce the chimney temperature. It forms a state of medium-high temperature-medium temperature-high temperature alternation, and various beneficial microorganisms grow and multiply rapidly in the temperature range suitable for beneficial microorganisms.

3. Improve the permeability of raw material pile

The tipping system can process the materials into small pieces, making the thick and dense raw materials bulky and elastic, and forming appropriate pores.

4. Adjust the water content of raw material pile

The suitable water content of raw material fermentation is above 55%, and the water content standard of finished organic fertilizer is below 20%. In the fermentation process, biochemical reaction will produce new water, and the consumption of raw materials by microorganisms will lead to the loss of carrier and dissociation of water. Therefore, the water content will decrease in time with the fertilizer making process. In addition to the evaporation formed by heat conduction, the overturning of raw materials by the tipper will also form forced water vapor discharge.

5. Special requirements for composting process

For example, crushing raw materials, giving raw materials a certain shape or realizing quantitative replacement of raw materials.

The organic fertilizer composter is mainly applicable to farms of various scales, and its application value is worthy of affirmation. The production of organic fertilizer in the fermentation tank mode is to place raw materials in the fermentation tank, and the materials will be overturned, stirred and broken in the tank, so that the materials can be fermented, matured and degraded. It is easier to obtain stable product performance than static compost, and the odor control effect is better.

Economical and practical compost turning machine

1. The track type compost turner is composed of mixing and shifting. It can realize the functions of air permeability, crushing and loosening when working. It is a common equipment for organic fertilizer production.

2. Under the action of the shift machine, the compost turner machine can change the composting production from single tank to multi tank fermentation, and can change the tank at will in multiple tanks, realizing the use of one machine with multiple tanks.

3. Compost turning machine composts evenly without agglomeration, the fermentation temperature rises quickly, and the dehydration and drying effect is good. Greatly reduce labor intensity, reduce production labor and save costs.

Working Principle

In recent two years, with the rapid development of social economy, we believe that people are more and more familiar with the organic fertilizer grinder, but we often encounter the problem of organic fertilizer composting. So how do we control these steps in this process? Now let’s see.

Water conditioning, water is necessary for microbial growth. During composting, 50-60% water (by weight) is conducive to microbial synthesis. The water content of livestock manure is 75-80%, and straw with low water content is usually used for conditioning.

The control of fermentation temperature is one of the important conditions for the normal fermentation of organic materials. In cold climate areas, heating and heat preservation measures should be taken to ensure the normal stop of fermentation process. At present, the economic and feasible method is to use solar energy to heat and heat materials. The greenhouse principle can be applied to the design of fermentation equipment. The fermentation equipment shall be made of PVC or glass fiber reinforced plastic roof materials and wall materials with good light transmission performance and durability. The fermentation equipment should be well sealed and well insulated in winter; At the same time, it shall be convenient for ventilation and provide oxygen for material fermentation.

Regulate carbon nitrogen ratio

Generally speaking, the C/N ratio of livestock manure is lower than 20:1, while that of straw is higher than 50:1. If the C/N ratio of the fermentation material is adjusted to 25-35:1, on the one hand, a part of straw can be added to livestock manure to adjust the C/N ratio, and on the other hand, the moisture content of straw is low.

Pile up

Aeration is an important factor affecting composting temperature and fermentation effect. The purpose of turning the pile is to improve the ventilation condition in the pile, distribute water, promote the propagation of high-temperature beneficial microorganisms, make the pile temperature reach 60~70 ℃, accelerate the transformation of fermentation materials, so as to achieve the purpose of average mixing, heating and decomposition. The materials can be turned over manually, or by wheeled dumpers, loaders, deep groove aerobic dumpers and other machines. In the process of fermentation, it is suitable to turn it for 1-2 times a day.

screening

In order to improve the commercial value of organic fertilizer products and facilitate packaging and storage, the screening process is usually used to separate large materials. There are many kinds of screening equipment, such as cylinder screen, vibrating screen, etc. In order to reduce investment, manual screening can also be used. The materials above the screen can be landfilled or reused as fermentation auxiliary materials, and the materials below the screen can be used as organic fertilizer products.

The fuel consumption of a compost turning machine is very small. It can turn 500 cubic meters an hour. If you use a forklift to turn 500 cubic meters, how much time and fuel consumption will it take, and the effect It’s incomparable to a dedicated turner. Therefore, buying a compost turning machine is the right choice to reduce costs and improve the quality of organic fertilizer products.

Organic fertilizer composter is the core equipment of aerobic dynamic composting. As a new type of machinery, it is unknown in the national product catalog, but it has rapidly multiplied in the fertilizer machinery and equipment family, becoming a tool to replace manual and forklift dumping, and is the mainstream product that affects the development trend of the composting industry. The importance of organic fertilizer composter stems from its role in composting production:

1. Mixing effect in raw material conditioning

In order to adjust the carbon nitrogen ratio, pH and water content of raw materials, some auxiliary materials must be added to the compost. The main raw materials and various auxiliary materials are roughly stacked together in proportion, which can be evenly mixed by the dumper to achieve the purpose of tempering.

2. Adjust the temperature of the raw material pile

During the operation of the stacker, the raw material particles fully contact and mix with the air, so that a large amount of fresh air can be stored in the material stack, which is conducive to the active production of fermentation heat by aerobic microorganisms and the improvement of the stack temperature; When the temperature is high, adding fresh air can reduce the chimney temperature. The state of medium temperature high temperature medium temperature high temperature alternation is formed, and various beneficial microorganisms are rapidly growing and reproducing in the temperature range suitable for beneficial microorganisms.

3. Improve the permeability of raw material pile

The turnover system can process the materials into small pieces, making the thick and dense raw material pile fluffy and elastic, forming appropriate pores.

4. Adjust the water content of the raw material pile

The suitable water content of raw material fermentation is above 55%, and the water content of finished organic fertilizer is below 20%. In the process of fermentation, new water will be produced by biochemical reaction, and the consumption of raw materials by microorganisms will cause the water to lose its carrier and become free. Therefore, the water content will decrease in time with the fertilizer making process. In addition to the evaporation caused by heat conduction, the turning of raw materials by the organic fertilizer composter will also cause forced water vapor emission.

5. Special requirements for composting process

For example, crushing raw materials, giving a certain shape to the raw material pile or realizing quantitative replacement of raw materials.

The oxygen consumption of compost is related to the content of organic matter in compost raw materials. The more organic carbon in compost materials, the greater the oxygen consumption. The suitable oxygen concentration of raw materials for chicken manure organic fertilizer production enterprises in the composting process is 18%. When the oxygen concentration is lower than 18%, the life activities of microorganisms in the good composting process are limited, which is easy to make the compost enter the anaerobic state and produce odor.

Many customers are concerned about whether the materials in the production of organic fertilizer will corrode the organic fertilizer peripheral equipment. If the material corrodes the machine, the service life of the turnover machine and equipment will be shortened, and the production cost of organic fertilizer will increase, which is not a cost-effective investment for enterprises.

However, the manufacturer of the organic fertilizer turnner clearly told everyone here that the production of organic fertilizer would not cause corrosion to the tipper. If it is not used for a long time, the equipment needs to be thoroughly cleaned, otherwise it will cause corrosion to the machine. This is because if the machine is not used for a long time, the residual substances in the machine will combine with the water molecules in the air to form a large amount of water, and the contact parts will be corroded after a long time of contact with the machine, but this will not happen in the normal production cycle.

Composting is a process in which organic matter is continuously degraded and stabilized under certain conditions through the action of microorganisms, and produces a product suitable for land use. Under the action of microorganisms, the organic fertilizer composter will make various organic substances in the composting process difficult to decompose, stable and easy to be absorbed by crops.

Inoculum. Adding microbial agents (microbial agents) to livestock manure can speed up the fermentation of compost. Adding stable fertilizer with good decomposability or compost with 10% – 20% of raw materials can speed up fermentation. During composting, microbial communities are formed in a natural way and participate in the fermentation of organic wastes and the decomposition of humus compounds.

The size of the compost material. With the movement of microorganisms on the surface of organic particles, reducing particle size and increasing surface area will promote microbial activity and accelerate composting. On the other hand, if the raw materials of the chicken manure organic fertilizer plant are too thin, it will hinder the air flow in the pile layer, reduce the amount of oxygen available in the pile layer, and then slow down the activity of microorganisms. Therefore, in order to speed up the fermentation process, it is necessary to minimize the particle size of composting materials on the premise of ensuring air permeability. Livestock manure is a kind of thick paste, which usually requires adding a lot of materials to increase the porosity.

7. PH is also one of the important factors affecting the growth of microorganisms. Generally speaking, the pH value most suitable for microorganisms is neutral or weakly alkaline. High or low pH makes composting difficult. In addition, pH also affects nitrogen loss, so when pH is higher than 7.0, nitrogen will volatilize in the form of ammonia. However, generally speaking, the pH of livestock manure can meet the requirements of fermentation.

Automatic packaging machine is an indispensable production equipment of NPK production line, which improves the efficiency of the whole production process.
