Composting and fermentation technology of cow dung Manure tipping machine
2023/06/17
Using static composting technology, a mixture of raw materials such as cow dung is stacked on a base mat made of small wooden blocks, broken straw or other materials with good air permeability. The base cushion with good air permeability wraps the ventilation pipe, and the ventilation pipe is connected with a blower that supplies or extracts air to the stack. Build the pile according to the air permeability of the cow dung, the weather conditions and the distance that the organic fertilizer machine used can reach. Building a relatively high pile is conducive to heat preservation in winter. In addition, it is necessary to spread a layer of decomposed compost on the surface of the pile to moisturize and insulate the pile, prevent heat loss, prevent flies and filter ammonia and other gases that may be generated in the pile Smell.
The length of the stack is limited by the gas transport conditions in the stack. In the fertilizer production process, if the pile is too long, it will be difficult for oxygen to enter the position farthest from the blower. The formation of airflow channels in the pile will cause air to bypass most of the raw materials of the pile. When this happens, the pile becomes uneven and anaerobic may occur, and part of the compost cannot reach maturity; usually, harder solid conditioners (straw and wood chips) are added to maintain the aeration environment inside the pile. In order to make the air distribution more reasonable, cow dung or sludge must be thoroughly mixed with the conditioning agent before composting.
The supporting facilities of manure biological organic fertilizer equipment need alcohol generating stacker, organic fertilizer crusher, drum screening machine, horizontal mixer, organic fertilizer equipment, disc granulator, organic fertilizer fermentation equipment, discussion on the causes of malignant transformation of soil layer, professional knowledge, rotary drying equipment, cooler, screening machine, outer membrane machine, automatic packaging machine, belt conveyor and other machinery and equipment.
