Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, and in particular to raw material grinding equipment for food additive processing. Background Art

[0002] Food additives refer to natural or chemically synthesized substances added to food during the production, processing and storage of food in order to improve food quality and its color, aroma and taste, change food structure, prevent food oxidation, corruption, deterioration and meet the needs of processing technology. Food additives have become an important part of the modern food industry and an important driving force for technological progress and scientific and technological innovation in the food industry. The raw materials of food additives need to be ground during production.

[0003] In the process of grinding food additives, a special grinding device is required. Most grinding devices are composed of a box structure and a grinding roller. The grinding roller can crush the food additives in the box structure. The existing grinding equipment still has the following defects:

[0004] When the existing food additive grinding device is used, the food additives are directly piled inside the device, and the food additives are ground by controlling the single movement of the grinding roller. The ground food additives have powders or particles of different sizes, resulting in poor grinding effect, and generally can only be satisfied with the grinding of a single food additive. When two mixed ground food additives are needed, the two food additive raw materials need to be ground in turn, and then the two ground food additive raw materials are poured into the mixing device and mixed by the mixing device. The process is relatively cumbersome.

[0005] Therefore, the present invention provides a raw material grinding equipment for food additive processing to solve the above problems. Summary of the invention

[0042] As attached Figure 2 As shown, inverted L-shaped plates 38 are provided at both left and right ends of the shell 1, and the collection box 20 is stuck between the two inverted L-shaped plates 38 and is longitudinally slidably connected to the two inverted L-shaped plates 38. The L-shaped plates enable the collection box 20 to slide only along the front and rear directions to avoid swinging in the up and down directions during the sliding process.

[0043] As attached Figure 2 and Figure 4 As shown, a baffle 39 is provided on the side of the inclined plate 11 , and two baffles 39 are opposite to each other on the left and right sides. The baffles 39 can prevent the raw material blocks from falling from the two inclined plates 11 .

[0044] As attached Figure 1 and Figure 2 As shown, a through slot 40 is provided at the front end of the housing 1 , and the front end of the collection box 20 can extend out of the through slot 40 . Two handles 41 are provided at the front end of the collection box 20 to facilitate the staff to take out the collection box 20 .

[0045] As attached Figure 2 and Fig.10As shown, the grinding blocks 10 on the pressing plate 9 are arranged in two rows, and the upper and lower rows of grinding blocks 10 are staggered, so that the raw material block can be ground twice, thereby enhancing the grinding effect of the grinding blocks 10.

[0046] When the present invention is in use, in the initial state, the hinge point between the first connecting rod 27 and the first turntable 25 is at the right part of the first turntable 25, the hinge point between the second connecting rod 28 and the second turntable 26 is at the left part of the second turntable 26, the housing 1 is on the horizontal ground, the staff adds the food additive raw materials to be ground into the feeding funnel 8, the two feeding funnels 8 can add two different raw materials, and then start the motor 21;

[0047] The output end of the motor 21 drives the active bevel gear 22 to rotate, the active bevel gear 22 drives the driven bevel gear 23 to rotate, the driven bevel gear 23 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the two conveying wheels 6 to rotate synchronously, the feeding trough 7 rotates synchronously with the conveying wheels 6, when one of the feeding troughs 7 rotates to just below the feed port 3, the raw materials in the feeding funnel 8 fall from the feed port 3 into the feeding trough 7 below it, the raw materials enter the cylindrical shell 2, and then rotate with the feeding trough 7 to above the discharge port 4, and fall from the discharge port 4 into the box body 13 below the cylindrical shell 2, and the raw materials in the box body 13 are located between the two crushing plates 16 facing each other front and back, the smaller raw material blocks directly fall from the multiple through holes 14 to below the flat plate 12, and are located between the two inclined plates 11, and the larger raw material blocks continue to remain in the box body 13;

[0048] When the rotating shaft 5 rotates, it will drive the first bevel gear 36 to rotate, the first bevel gear 36 drives the second bevel gear 37 to rotate, the second bevel gear 37 drives the disk 34 to rotate, and the disk 34 drives the plug post 35 to rotate. Since the plug post 35 is located in the yield groove 33 on the right part of the swing rod 32, when the plug post 35 rotates, it will drive the swing rod 32 to swing back and forth, the swing rod 32 drives the cylindrical rod 17 to rotate alternately in forward and reverse directions, and the cylindrical rod 17 drives the rotating rod 18 to rotate alternately in forward and reverse directions. When the rotating rod 18 rotates clockwise, the rotating rod 18 starts to drive the two pull rods 19 to move in relative directions, and the two pull rods 19 drive the two U-shaped plates 15 to move in relative directions. The two U-shaped plates 15 drive the front and rear relative The two crushing plates 16 gradually approach each other. When the crushing plates 16 contact the raw material blocks in the box body 13, the two crushing plates 16 facing each other gradually crush the larger raw material blocks. The larger raw material blocks are split into smaller raw material blocks, and then reach between the two inclined plates 11 from the multiple through holes 14. When the rotating rod 18 rotates counterclockwise, the rotating rod 18 starts to drive the two pull rods 19 to move in opposite directions. The two pull rods 19 drive the two U-shaped plates 15 to move in opposite directions. The two U-shaped plates 15 drive the two crushing plates 16 facing each other to gradually separate. When the two crushing plates 16 return to the initial position, the raw material blocks in the next feeding chute 7 fall between the crushing plates 16 facing each other.

[0049] When the motor 21 rotates, it will directly drive the driving pulley 30 to rotate. The driving pulley 30 drives the two driven pulleys 29 to rotate through the belt 31. The two driven pulleys 29 respectively drive the first turntable 25 and the second turntable 26 to rotate in the same direction. The first turntable 25 drives the first connecting rod 27 to rotate. In the initial state, the first connecting rod 27 pulls the rear pressure plate 9 to move first to the left and then to the right, and then reciprocates. At the same time, the second turntable 26 drives the second connecting rod 28 to rotate. In the initial state, the second connecting rod 28 pulls the front pressure plate 9 to move first to the right and then to the left, and then reciprocates. The two pressure plates 9 always move in opposite directions. The ends of the pressure plates 9 slide horizontally along the two upper and lower opposite guide rods 24, and the multiple grinding blocks 10 on the pressure plates 9 move with the pressure plates 9.

[0050] The raw material block between the two inclined plates 11 falls along the inclined surface to between the two pressing plates 9, and the grinding blocks 10 on the two pressing plates 9 grind the raw material block into powder. During the grinding process, the baffle 39 can prevent the raw material block from falling from the ends of the two inclined plates 11 without being ground. The grinding blocks 10 on the pressing plate 9 are arranged in two rows, upper and lower, and the two rows of grinding blocks 10 are staggered, which can grind the raw material block twice, so that the ground raw material powder particles are more uniform, thereby achieving a better grinding effect. The ground raw material powder falls into the collection box 20 from the gap between the two adjacent grinding blocks 10, and the two raw material blocks fall into the collection box 20 after grinding. The staff directly obtains the mixed raw material powder, which is convenient for the staff to carry out subsequent processing, thereby improving the processing efficiency of food additives;

[0051] After the raw material block is ground, the staff can turn off the motor 21 and then pull the two handles 41 forward. The two handles 41 drive the collecting box 20 to slide forward along the inverted L-shaped plate 38 and extend out of the through slot 40. The two inverted L-shaped plates 38 can prevent the collecting box 20 from swinging up and down during the sliding process. After the collecting box 20 is separated from the outer shell 1, the staff obtains the raw material powder in the collecting box 20 and then processes it subsequently.

[0052] The motor 21 in the present invention is a prior art, and its circuit adopts a currently commonly used connection method, and its specific structure will not be described in detail here.
