Before composting and fermentation in the livestock and poultry house, estimate the amount of manure produced by livestock and poultry in one day. Cover the manure with an appropriate amount of dry grass ash, furfural residue and other organic matter every day, and then inoculate the fermentation bacteria according to the proportion. Months or longer (time depends on the specific situation) to remove once, so that the fermentation process is completed in the barn. This not only eliminates the need for composting sites and reduces the amount of labor, but also can use biological heat production to increase the temperature of the house and save heating costs. It has strong practical value in the northern region in winter.
In the organic fertilizer npk manufacturing process by using pig manure sewage and pig manure, the cross section of the manure storage tank is a regular octagonal structure, and a number of stirring guide bars are evenly distributed along the circumferential direction in the manure storage tank; The septic tank is arranged in a vertical direction, and the stirring guide strips are in a rhombus-shaped structure and are respectively located on the corners of the septic tank.
The overall structure design of the spherical organic fertilizer granulator is equipped with a corresponding rounding device on the granule press. This machine is the best for powder extrusion and granulation. It not only solves the difficult granulation of rotary drum granulator and double roller granulator structure, but also solves the granulation problem of poor granulation and molding, and also solves the process of throwing balls. At the same time, by improving the structure of the flat die, increasing the rotational speed of the flat die, adopting a threaded gap adjustment device for the flat die and the roller, and changing the traditional gasket method of adjusting the gap between the flat die and the roller to overcome the problems of high labor intensity and poor ball-forming effect. The existing granulator produces biological fertilizers with high temperature sterilization and poor granulation, and developed a new straw manure mixed organic fertilizer granulator with reasonable design, simple structure, easy operation, normal temperature preservation, and smooth granules.
