Functions of Compost Turners

-

Composting is a process in which the manure collected in the fecal canal of the farm is dehydrated by a solid-liquid separator, and then mixed with crop straw or sawdust according to a certain proportion to adjust the carbon nitrogen ratio, and add microbial strains. Through the up and down tossing of the composting machine, aerobic fermentation is carried out to form organic fertilizer and soil amendment, so as to achieve the purpose of harmless, reduction and resource utilization.

The emergence of the compost turning equipment is gradually replacing manual material turning. It has the following five functions in composting.

1. The special requirements of composting technology are realized, such as crushing raw materials, realizing quantitative displacement of raw materials or giving certain shape to raw materials pile.

2. Improve the permeability of raw material pile: the turning system can process the materials into small lumps, and make the thick, elastic and dense raw material pile become fluffy and form appropriate porosity.

3. Mixing function in raw material conditioning: in fertilizer making process, some auxiliary materials need to be added in order to adjust the carbon nitrogen ratio, water content and ph value of raw materials. The agitator can be used to mix the main raw materials roughly stacked together according to the proportion with various auxiliary materials, so as to achieve the purpose of quenching and tempering.

4. Adjust the moisture content of raw material pile: the suitable moisture content of raw material fermentation is about 55%, and the moisture standard of finished organic fertilizer is below 20%. In fermentation, the consumption of raw materials by microorganisms will make water lose carrier and free out, and biochemical reaction will generate new water. Therefore, in addition to evaporation formed by heat conduction, forced steam emission will be formed when the material is turned by the compost turner, which can reduce the water content in time with the process of fertilizer production.

5. Adjust the temperature of the raw material windrow: during the operation of the compost turner, the raw material pellets and air are fully contacted and mixed. When a large amount of fresh air is kept in the pile, the aerobic microorganisms will become active, thus producing fermentation heat and increasing the windrow temperature; when the temperature is high, fresh air can be added to reduce it.

  The organic biogas residue fermentation tank   is ventilated, oxygenated, agitated and deodorized, purified and sprayed, and the temperature of the fermentation material is controlled between 55-75 degrees. The biogas residue raw material after high temperature aerobic fermentation can be used in feed industry and animal husbandry. Auxiliary raw materials for industry, environmental protection industry, ecological agriculture, organic fertilizer industry. Biogas residue is rich in nutrients such as nitrogen, phosphorus, potassium and mineral salts, and is suitable for the development and growth of crops and livestock. Process flow of biogas residue fermentation tank The organic biogas residue fermentation pot   uses biogas residue and other organic wastes as fermentation raw materials. The crushed materials enter the fermentation tank for heating and inoculation. At the same time, aeration is provided, and organic fertilizer fermentation agent is added to assist fermentation.

  More and more farm wastes use organic fertilizer production machine   to realize waste utilization and turn waste into treasure. Organic fertilizer turning compost   machine is a kind of fermentation equipment with a wide utilization rate. Among them, in small organic fertilizer processing, organic fertilizer self-propelled turning compost   machine   is the most used one. The equipment can deal with manure problems well, turn over and ferment the animal manure into organic fertilizer, and reduce the pollution and damage of manure to the environment. So how does the self-propelled turning machine perform turning? What are the manufacturers and prices of the self-propelled turning machine?It is a compost   equipment that is driven by diesel engine and electric power and needs to be operated by humans in real time. The self-propelled compost   machine is a kind of equipment that walks on the ground. The four-wheel design allows the compost   machine to move forward, turn, and reverse,
