The invention discloses a grain bin transverse nitrogen-charging adjustment system. The system comprises a grain storage bin and a membrane separation nitrogen generator, and further comprises two air-adjusted air duct structures; the air-adjusted air duct structures comprise wall air ducts, open-close doors, main air ducts and a plurality of vertical support air pipes, a plurality of air holes are formed in the vertical support air pipes, and nitrogen supplying air holes are connected to one end of the nitrogen supplying pipe in a butt joint mode; connectors which are connected with the wall air duct of one air-adjusted air duct structure in a butt joint mode are arranged at the other end of the nitrogen supplying pipe, air inlets of a nitrogen preparation main engine are connected to one end of an air return pipe in a butt joint mode, and the connectors which are connected with the wall air duct of another air-adjusted air duct structure in a butt joint mode are arranged at the other end of the air return pipe; a nitrogen supplying on-off valve is arranged on the nitrogen supplying pipe, and a nitrogen concentration detection instrument and a pressure determinator are all arranged on the air return pipe. The grain bin transverse nitrogen charge air-adjusted system has the advantages that a grain bin can be effectively filled with nitrogen, accordingly, grain piles in the grain bin can be effectively subjected to disinfestation, mould inhibition and preservation, and the system is good in gas distribution uniformity, high in nitrogen efficiency and less in nitrogen waste.

The invention relates to an anticoccidial traditional Chinese medicine preparation and a preparation method thereof. The anticoccidial traditional Chinese medicine preparation mainly comprises the following components: giant knotweed, notoginseng, rhubarb and halofuginone. The anticoccidial traditional Chinese medicine preparation has the characteristics that the anticoccidial traditional Chinese medicine preparation not only can quickly inhibit and kill coccidia oocysts, but also effectively stops bleeding, quickly repairs the intestinal impaired mucosa, effectively prevents the coccidiosis from recurring, and does not affect the feed-meat ratio of poultry; meanwhile, the solution form is adopted, and the anticoccidial traditional Chinese medicine preparation can be evenly dispersed in water, so that the anticoccidial traditional Chinese medicine preparation is convenient to take, waste is reduced, the dose is ensured, the bioavailability is improved, and a drinker is not blocked.

There is an adjustable transmission device at the left end of the rotating shaft, the top of the transmission device has a first sleeve, the top of the side of the first sleeve has a cylindrical body, the side of the cylinder has a fourth through hole, the outer end of the fourth through hole has a first nozzle, and the first rotating shaft There is a cam on it, there is a first cross bar on the right side of the cam, there is a cylindrical box on the right side of the first cross bar, there is a circular plate in the cylindrical box, there is an eighth through hole on the side of the circular plate, and there is a one-way valve, a spraying device is arranged at the bottom of the cylindrical box body, and a partition is arranged in the first box body. The invention is easier to water and spray pesticides. The device can automatically spray pesticides on the grapes on the top of the grape trellis and at the same time water the nutrient solution on the roots of the grapes, which greatly improves the efficiency of workers and is convenient and quick to use.

The invention discloses a processing method of washing-free persimmon cake, and belongs to the field of agricultural products processing engineering. According to the technical scheme, the processing method comprises the following steps: removing peel and washing; performing radio processing and heating; drying; performing die molding; and frosting and packaging. When the radio heat treatment is adopted before drying persimmon, internal temperature of persimmon can be rapidly increased and the effects of disinfestation and sterilization can be realized; when a heat pump dehumidification drying device is used cooperatively, softening and astringency removal can be effectively performed on the persimmon, drying speed can be increased, and drying quality can be improved, so that the processing technology and quality of the persimmon cake are greatly improved.
