The powder equipment is usually composed of a driving device (motor, speed reducer), a crushing chamber, grinding medium (such as grinding roller, grinding disc, hammer head, steel ball, etc.), a classification system (such as cyclone separator, screen mesh, air flow classifier) and dust collecting device. After the material enters the crushing chamber, it is repeatedly impacted, rubbed and sheared under the action of high-speed rotating grinding medium or air flow, and gradually refined to the target particle size, and then the qualified fine powder is separated out through the classification system, and the coarse particles return to continue crushing. According to the crushing principle and structural difference, the powder equipment can be divided into mechanical type (such as Raymond mill, ball mill, jet mill, ultrafine grinder), air flow type (such as fluidized bed jet mill), impact type (such as impact crusher) and shearing type (such as colloid mill).

[0031] Examples

[0032] Please refer to Figs. 1-3As shown, the embodiment provides a food beating hammer head, which comprises a hammer head body 1, an assembly channel 11 is formed at one end of the hammer head body 1, and an external mounting rod is arranged in the assembly channel 11. The beating side surface 12 is arranged at both sides of the hammer head body 1. At least one disturbance groove 13 is formed on the end face of the other end of the hammer head body 1, the length of the slot of the disturbance groove 13 is less than the length of the end face, and the grinding protrusions are formed at both sides of the slot of the disturbance groove 13.

[0033] The hammer head body 1 rotates on the external mounting rod, the beating side surface 12 disturbs the airflow in the rotating direction and beats and crushes the materials lifted up; the end face of the other end of the hammer head body 1 is a circular arc surface, and the arrangement of the external tooth ring is the same, in the rotating process of the hammer head body 1, the end face and the external tooth ring grind the materials, and the disturbance groove 13 and the disturbance protrusion 14 form a low pressure area in front of the front end face of the disturbance protrusion 14 and the inner side face of the disturbance groove 13 in the advancing process, increase the airflow velocity in front of the front end face of the disturbance protrusion 14 and the inner side face of the disturbance groove 13, so as to drive the materials embedded between the external tooth rings to separate from the tooth ring, avoid excessive accumulation in the gap of the tooth ring, affect the crushing effect of the tooth ring on the materials, and improve the crushing efficiency.

[0034] Further, the disturbance groove 13 penetrates the hammer head body 1 along the width direction of the end face, so that the airflow can flow out from both sides of the disturbance groove 13, drive the material powder to move in a larger range, reduce the blockage of the material powder, and avoid the material powder from being lifted up and falling back between the tooth rings. In the embodiment, the disturbance groove 13 is two, and the two disturbance grooves 13 are arranged at intervals in the length direction of the end face, which effectively increases the blowing effect on the material powder between the tooth rings. In the embodiment, the front and rear side faces of the disturbance groove 13 are both flat surfaces 131, which further improve the airflow velocity in front of the inner side face of the disturbance groove 13 by driving the airflow through the flat surface 131, and improve the blowing effect on the accumulated materials.

[0035] Specifically, the hitting side 12 includes a flat hitting section 121 and a concave hitting section 122, and the concave hitting section 122 is provided with a hitting groove. The flat hitting section 121 and the concave hitting section 122 hit the flying material powder, increase the movement speed of the material powder, and thus have a better breaking effect after hitting the gear ring. During the movement, the concave hitting section 122 further disturbs the airflow inside the powder hitting device, pushes the material to collide with the gear ring from multiple directions, and improves the powder hitting efficiency. In the embodiment, the concave hitting section 122 is located on the side of the hitting side 12 close to the disturbance groove 13, i.e., the concave hitting section 122 is located at the bottom inside the powder hitting device. The concave hitting section 122 can form a better disturbance effect from the bottom, provide multiple directions of thrust to the material when the hammer head body 1 moves downward, lift the material sinking at the bottom when the hammer head body 1 moves upward, increase the breaking frequency, make the powder after the powder hitting treatment more delicate, and improve the powder hitting effect. In the embodiment, two grooves 1221 are provided on the concave hitting section 122.

[0036] In addition, the weight of the hammer head body 1 also affects the crushing efficiency. Specifically, lighter hammers are suitable for crushing brittle and low-fiber materials (such as grains), but the impact force is small, and the crushing effect on high-hardness or high-toughness materials is poor, which may increase the number of repeated crushing and reduce the efficiency. The impact force of heavier hammers is stronger, which can effectively crush fibrous and high-toughness materials (such as herbal materials), but it is too heavy for brittle and low-fiber materials, which may cause over-crushing and produce too much fine powder. For food raw materials, it may also damage the nutritional ingredients.

[0037] Therefore, in a preferred embodiment, a counterweight assembly 2 is detachably connected to the hammer head body 1. The counterweight assembly 2 detachably connected to the hammer head body 1 adjusts the weight of the hammer head body 1 to flexibly adapt to the requirements of different materials for breaking particle size, and has better practicality.

[0038] Please refer to Fig. 2 and Fig. 3 Specifically, the adjacent other two sides of the hammer head body 1 are provided with corresponding installation grooves 15, and the installation grooves 15 are provided with installation channels 16. The counterweight assembly 2 includes a counterweight 22 and a flexible sleeve 21 sleeved outside the counterweight 22. The flexible sleeve 21 is a silica gel piece, and the side surfaces of the flexible sleeve 21 are provided with outwardly extending installation eaves 211. The flexible sleeve 21 and the counterweight 22 are embedded in the installation channels 16, and the installation eaves 211 extend into the installation grooves 15. The installation channels 16 install the counterweight assembly 2, the installation eaves 211 of the flexible sleeve 21 are located in the installation grooves 15 and abut against the inner side walls of the installation grooves 15, which improves the installation stability of the counterweight assembly 2, and the flexible installation eaves 211 realize the detachable connection of the counterweight assembly 2 by utilizing the flexibility of the installation eaves 211. The counterweight 22 is made of different materials to obtain different weights, such as aluminum blocks, steel blocks, and tungsten-nickel-iron alloys.

[0039] In the embodiment, the two beating side surfaces 12 are inclined outward from one side of the assembly channel 11 in an "8" shape. The inclined beating side surfaces 12 change the movement path of the material after the material collision process, and improve the side shearing effect of the hammer head body 1. Further, the shape of the counterweight 22 is the same as that of the hammer head body 1, and the assembly channel 16 is symmetrically arranged on the central axis of the hammer head body 1. The counterweight 22 is arranged on the central axis of the hammer head body 1, and the shape of the counterweight is matched with the shape of the hammer head body 1, so that the center of gravity of the hammer head body 1 is located on the central axis, and the center of gravity of the hammer head body 1 is not offset during the movement process, which affects the powder beating effect on the material.

[0040] The embodiment also provides a powder beating device, which adopts a hammer structure to further crush the powder, and obtains a desired powder mesh number, and the hammer structure adopts the food powder beating hammer head.

[0041] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
