Turning machine, is a new machinery, has not yet been included in the national product, but in the organic fertilizer equipment family has developed rapidly, has begun and will gradually replace the manual, forklifts for material turning era. Then there is the compost turning machine which applications it: first the raw material in the mixing function quenched. Composting, in order to adjust the raw nitrogen ratio, pH, water content, etc., must add some accessories. Can rely on turning machines do stir roughly proportionally stacked together with a variety of major raw materials are uniformly mixed to achieve the purpose of quenching. The second point is the temperature of the mediation stockpile. Turning machine in the work process, raw aggregate sufficient contact with the air, mixed with a lot of conservation when the stockpile of fresh air, it will become active aerobic microbial fermentation to produce heat, so that the reactor temperature rise; when the temperature high, fresh air coming up would enable the reactor temperature drop. Formation temperature - temperature - temperature - temperature cycle status, a variety of beneficial microbial adaptation to temperature in its segment growth and reproduction. The third point is to improve the permeability of the stockpile. Material handling systems can turning into small clumps, so that the texture of thick, dense materials pile becomes fluffy, flexible, form a suitable porosity. The fourth point is to adjust the raw water reactors. Suitable fermentation feedstock moisture content is about 55% down, finished organic fertilizer water standard is 20% or less. Fermentation, biochemical reaction will generate new water, microbial consumption of raw materials will also lose water carrier freed. Therefore, in addition to the formation of heat conduction by evaporation, turning machines turning raw form of mandatory water vapor distribution, which can reduce the moisture in a timely manner with the composting process. The last point is required to achieve a special composting process. Such as crushed materials, giving the stockpile materials to achieve a certain shape or quantitative displacements.
