Description
Technical Field
[0001] This utility model belongs to the technical field of antibiotic-reduced feed production equipment, specifically a herbal medicine pulverizing device for antibiotic-reduced feed for livestock. Background Technology
[0002] Under the trend of "antibiotic reduction" in livestock farming, traditional Chinese medicine (TCM) has become an important alternative to antibiotics as feed additives due to its natural and multifunctional properties (such as enhancing immunity, antibacterial and growth-promoting effects), and its low tendency to induce drug resistance. The active ingredients in TCM determine the final effect of the feed additive. Grinding, as a key pretreatment step in the preparation of TCM feed additives, involves pulverizing dried TCM to a fineness of 80 mesh or higher to meet the digestive and absorption needs of animals. Currently used grinding equipment (such as hammer mills, universal mills, and high-speed turbine mills) inevitably generates a large amount of frictional heat during grinding due to the intense impact, friction, and shearing between the rotating grinding discs or blades and the TCM and inner cavity walls. This results in high internal temperatures within the grinding chamber, destroying some heat-sensitive components in the TCM and reducing the content of active ingredients, thus weakening the effect of TCM as a feed additive. Therefore, it is necessary to design a TCM grinding device for livestock antibiotic-reducing feed that can reduce the internal temperature of the grinding chamber and prevent the reduction of active ingredient content after grinding. Utility Model Content
[0003] The purpose of this invention is to provide a herbal medicine pulverizing device for livestock antibiotic-reducing feed that can reduce the internal temperature of the pulverizing chamber and prevent the reduction of active ingredient content after pulverizing herbal medicines, thereby solving the technical problem of loss of active ingredients in herbal medicines due to high internal temperature of the pulverizing chamber.
[0004] To solve the above technical problems, the technical solution of this utility model is: a herbal medicine pulverizing device for reducing antibiotics in livestock feed, including a fixed frame, a pulverizing mechanism, and a cooling mechanism, wherein the pulverizing mechanism is fixedly connected to the fixed frame;

[0010] Furthermore, a guide baffle is inclinedly arranged inside the grinding box. Two guide baffles are symmetrically arranged. One end of the guide baffle is fixedly connected to the upper side of the inner wall of the grinding box, and the other end is located above the grinding roller assembly.
[0011] Furthermore, the water pump input end is connected to the cold water tank, the return water pipe output end is connected to the cooling pool, and valves are installed on both the inlet and outlet.
[0012] This utility model has the following advantages compared with the prior art:
[0013] This invention adds a water-cooled jacket to the outside of the crushing mechanism, and continuously pumps cold water into the jacket for heat exchange, thereby reducing the temperature in the working cavity of the crushing mechanism in a timely manner. This prevents the temperature from accumulating too high in the working cavity, which could lead to the loss of heat-sensitive active ingredients in the Chinese herbal medicines due to heat. This ensures that the crushed Chinese herbal medicine powder can still have various beneficial effects as a feed additive. Attached Figure Description
