AI Technical Summary
Most existing vacuum spraying equipment is large machinery, which is not suitable for individual farmers. The liquid components are sprayed unevenly, heat-sensitive substances are easily lost, and the operation is complicated, which cannot meet the needs of small-scale equipment for economy and ease of operation.
A vacuum spraying device was designed, including a tank, a sealing cap, a vacuum component, and a spraying component. It utilizes a negative pressure environment to self-absorb gas and liquid. The nozzle is located at the center of the sealing cap. Combined with a stirring component and a flow regulating valve, it achieves efficient mixing and uniform spraying of gas and liquid, reduces the equipment's reliance on external pumping equipment, and simplifies the structure.
It achieves uniform adhesion of liquid components to the surface of feed pellets, improves nutritional value, reduces production and maintenance costs, and is simple and convenient to operate, meeting the needs of individual farmers.
