Double screws turning machine is suitable for fermentation composting of livestock waste, sludge waste, sugar refinery filter mud, straw sawdust and other organic waste. It overcomes the limitation of the width and depth of the traditional groove turning machine. It is suitable for aerobic fermentation, and can be used in conjunction with solar energy fermentation room, fermentation tank and moving machine. It can be used together with the moving machine to realize the function of many of slots for one machine.
1. Mixing function in raw material conditioning.
In order to adjust the ratio of carbon to nitrogen, pH and water content of raw materials, some auxiliary materials must be added. The main raw materials and various auxiliary materials roughly stacked together according to the proportion can be stirred by the tipper to achieve the purpose of tempering.
2. Adjust the temperature of the raw material pile.
During the operation of the tipper, the raw material pellets are fully contacted with and mixed with the air, and a large amount of fresh air can be kept in the pile, which is conducive to the active production of fermentation heat by aerobic microorganisms, and the stack temperature is increased; when the temperature is high, the fresh air supplement can reduce the stack temperature. The formation of medium temperature - high temperature - medium temperature - high temperature alternation state, all kinds of beneficial microorganisms grow and propagate rapidly in the adaptive temperature section.
3. Improve the permeability of the feedstock stack.
The turning system can process the material into small lumps, making the thick and dense material pile become fluffy and elastic, and form appropriate porosity.
4. Adjust the moisture content of raw material pile.
The suitable moisture content of raw material fermentation is above 55%, and the moisture standard of finished organic fertilizer is below 20%. During fermentation, biochemical reaction will generate new water, and the consumption of raw materials by microorganisms will make water lose carrier and free. Therefore, in addition to evaporation formed by heat conduction, the forced steam emission will be formed when the material is turned by the tipper.
5. Realize the special requirements of composting process.
Such as the crushing of raw materials, giving a certain shape to the raw material pile or realizing the quantitative displacement of raw materials.
