Description

Multi-purpose grinder {MULTIPURPOSE MILL}

The present invention relates to a multi-purpose grinder, which relates to a multi-purpose grinder capable of finely pulverizing various crushing objects such as food raw materials and paints into uniform particles.

Generally, a grinder is used to finely pulverize various crushing objects such as food raw materials and paints into uniform particles. Among them, the food raw material grinder is used to crush grains using a crushing blade. Most of them are not crushed to the required particle size through a single crushing process, and the worker repeatedly supplies the crushed crushing object. And crushed to a desired particle size. Accordingly, there is a problem in that it takes a lot of work time according to the crushing process of manual work and also the work efficiency is deteriorated. In order to solve this problem, the number of times to crush the food raw material has been increased over several times by automatically supplying the crushed crushed material from one grain grinder rather than manually by the operator. However, when the crushing object is passed through a multi-purpose grinder over a number of times by using the crushing blade as described above, the pulverized blade powder is mixed with the crushed object due to friction between the crushing blades, so that a pure food pulverized product cannot be obtained. In addition, since the quality of the food raw material decreases because it is directly crushed by the grinding blade, and when the grinding blade becomes dull after a certain period of time, the time taken to crush the food raw material to the desired particle size increases, and if heat occurs during the grinding process, In the case of grains, there is a problem of being luxurious.

Therefore, in recent years, there is a need for a multi-purpose grinder capable of preventing impurities from being mixed in the process of crushing the food material, minimizing heat generation while maintaining the quality of the food material, and crushing the food material with a uniform particle size. do.

Hereinafter, the present invention will be described in more detail with reference to preferred embodiments. However, these examples are intended to illustrate the present invention in more detail, it will be apparent to those skilled in the art that the scope of the present invention is not limited thereby.

The grinder can be classified into a roll grinder, a millstone type grinder, an air flow grinder, a cyclone mill, and a high-speed grinder according to the driving method. Among them, the cyclone mill is suitable for manufacturing fine particle powder, can compact the machine, and is suitable for mass production as well as small quantity. The particle size of the powder can be adjusted by rotation speed or wind speed, and can be dried simultaneously with grinding. Fine and uniform particle size is required for stable food processing. Therefore, the fine powder milled in the cyclone mill is fine and has no deviation, and a lot of starch remains on the surface of the powder. In other words, the starch-damaged glass is low, and the processing suitability to the product is excellent. Since the cyclone mill is a self-grinding method in which the objects to be crushed are crushed and crushed, it is possible to prevent the crushing blades and the like from being abraded and mixed with the powder to be crushed. In addition, since the amount of air generated is high and the temperature rise is small, it is possible to prevent the crushing object from being gelatinized during the crushing process.

The present invention characterizes the shape of the wing portion 124 formed on the vortex surface 124a of the impeller 120, so that the object to be crushed is more smoothly crushed by the flow of air generated in the wing portion 124.

1 is a schematic diagram of a multi-purpose grinder according to an embodiment of the present invention, FIG. 2 is a perspective view and a cross-sectional view of an impeller according to an embodiment of the present invention, and FIG. 3 is a picture of an impeller according to an embodiment of the present invention .

The multi-purpose grinder according to the present invention, as shown in Figure 1, the housing 110 including a supply port 112 to be pulverized object and an outlet 114 through which pulverized pulverized object is discharged;

A central part 122, a pair of impellers 120 which are formed to extend apart from each other in a radially outer direction from the central part 122, include a plurality of wing parts 124, and are installed in the housing 110; And

It includes; a driving body for driving the impeller 120 of the pair;

The wing portion 124 is formed with a vortex surface 124a having a convex protrusion 124c,

The pair of impellers 120 are installed so that the vortex surfaces 124a formed on each face each other.

The crushing object flowing into the supply port 112 of the housing 110 flows by the flow of air generated by the rotation of the impeller 120. In this process, pulverization is caused by the shear force generated when the air collides with the crushing object, or the shear force generated by colliding the crushing objects flowing by the flow of air. In this process, the crushing target, which has been crushed, is discharged to the outlet 114 of the housing 110. The crushing particle size of the crushing object may be adjusted in proportion to the flow velocity of the air driven in the housing 110 and the time exposed to the flowing air. That is, the air-flow grinder as in the present invention is to control the time or crushing strength of the crushing process in order to adjust the particle size because the crushed particles are crushed evenly. To this end, the present invention controls the particle size of the grinding object to be crushed by adjusting the rotational speed of the impeller 120 and the time during which the impeller 120 rotates to drive before the grinding object is input and discharged in order to adjust the particle size of the grinding object. Is to do.

The impeller 120 driven to indirectly crush the object to be crushed may be largely divided into a central portion 122 and a wing portion 124, as illustrated in FIGS. 1 and 2. The center of the central portion 122 is coupled to a rotating shaft for driving the impeller 120, and the wing portion 124 is coupled around the central portion 122. Here, the wing part 124 is formed by connecting a plurality of wing parts 124 to one central part 122. According to an exemplary embodiment of the present invention, when the central part 122 rotates, the wing part 124 has a central part ( In order to prevent the impeller 120 from being driven in an eccentrically connected state from 122, the wing portions 124 are spaced at equal intervals. That is, the wing portion 124 is formed to extend radially outwardly at a predetermined angular interval from the center of the central portion 122. At this time, the impeller may be formed by any one of 4 blades with 4 blades 124, 6 blades with 6 blades, and 8 blades with 8 blades.

The pair of impellers 120 are rotationally driven in the opposite direction to each other by a driving body driving each. Here, when the driving body is selected as the motor 130, the rod-shaped rotating shaft beam 140 is provided between the impeller 120 and the motor 130 so that the impeller 120 is driven to drive the motor 130 or the motor ( 130) may be directly interlocked, and the impeller 120 may be directly driven to rotate. That is, the method in which the impeller 120 is driven to rotate is not limited to any one, and may be driven by various methods such as a general motor 130 or a device driven by using magnetic force. By forming the impeller 120 forward rotating and the vortex surfaces 124a of the reverse rotating impeller 120 facing each other, an air flow generating shear force is generated by the impeller. In addition, shear forces are generated as the crushing objects moving along the air flow collide with each other. On the other hand, the rotational speed of the impeller 120 for forward rotation and the impeller 120 for reverse rotation may be the same, but the present invention is not limited thereto, and the impeller 120 for forward rotation and the impeller 120 for reverse rotation are necessary to each other. It can rotate at different speeds. As described above, in order to rotate the impeller 120 that rotates forward and the impeller 120 that rotates reversely at different speeds, a pair of impellers 120 are respectively connected to a pair of drive bodies having different rotational speeds, or one drive body. The two impellers 120 may be connected by gears or pulleys.

The present invention is to form a bent on the vortex surface (124a) and the back surface (124b) of the front of the shape of the impeller 120, so that the grinding object can flow smoothly in the housing (110). First, the wing portion 124 is formed with a rear surface 124b on the opposite side of the vortex surface 124a, and the rear surface 124b of the wing portion 124 is convexly protruding than the central portion 122. Due to such a shape feature, by increasing the weight of the wing portion 124 located radially outside the center of the impeller 120, the impeller 120 is driven to rotate uniformly, so that the shear force can be uniformly applied to the object to be crushed. .

In addition, the wing portion 124, the vortex surface (124a) is preferably formed to protrude than the central portion (122). The pair of impellers 120 are provided so that the vortex surfaces 124a formed on the front surfaces of the wing portions 124 face each other. Accordingly, when the vortex surface 124a of the wing portion 124 is convexly projected, when the vortex surfaces 124a face each other during the process of the impeller 120 rotating, the vortex surfaces 124a and the vortex surfaces ( As a narrow space is formed between 124a), throttling occurs. As a result, the wind speed can be increased instantaneously and smoothly flowed into the food material, and the food material is crushed more smoothly.

In addition, by forming the protrusion 124c on the vortex surface 124a, a vortex is generated in the protrusion 124c so that the crushing object flows evenly once again, so that a shear force is applied to the crushing object. In addition, due to the protrusions 124c, the area between the vortex faces 124a and the vortex faces 124a facing each other is narrowed, and the wind speed is forcibly increased by the pressure difference that already exists. As such, when the wind speed increases instantaneously, the object to be pulverized can flow smoothly, and the object to be crushed is crushed more smoothly. As a result, the convection grinding efficiency and the pressure grinding efficiency can be increased by the protrusion 124c.

In particular, the specific gravity of dried vegetables is about 1.06 or less, and the specific gravity is relatively low. When crushing a crushed object having a low specific gravity such as dry vegetables, if a concave groove is formed on the vortex surface 124c rather than the convex protrusion 124c (see FIG. 4), the crushed object with low specific gravity stagnates inside the groove. As a result, a caking phenomenon in which the pulverized particles are hardened occurs, and accordingly, the tornado effect is reduced while the volume of the groove is substantially reduced, and the crushing efficiency may be deteriorated. However, the multi-purpose grinder according to an embodiment of the present invention has a convex protrusion 124c formed on the vortex surface 124c, so that even if a crushing target having a low specific gravity is crushed, caking phenomenon is prevented, thereby crushing efficiency It can prevent falling.

In addition, by forming the shape of the rear surface 124b and the vortex surface 124a of the wing portion 124, heat generated in the process of crushing the food raw material can be minimized. Therefore, the quality of the crushing object is prevented from being deteriorated by heat, and the production amount is increased by multiple tornadoes formed by friction between the wing part 124 and the air, and pulverization by smoothing the air flow inside the housing 110 Time can be minimized.

In addition, since the particle size of the particles to be pulverized can be adjusted in a customized manner, precision is improved and at the same time, there is no need to pulverize the pulverized object repeatedly, thereby reducing energy consumption. In addition, it can be mixed according to the type of food material to be crushed, and can also be crushed by mixing with a wet type food material. In the conventional food raw material grinder, since multiple tornadoes are not formed, in the case of the wet type food raw material, the specific gravity is high and is frequently caught between the crushing blades or the gaps of the device before crushing. However, in the present invention, food ingredients being crushed by multiple tornadoes generated by driving vortices and impellers generated from the protrusions 124c are injured once more, and other food ingredients and air and shear are generated to be crushed again. Can. Therefore, it can be smoothly crushed by being subjected to shearing force rather than being pinched by an apparatus or the like.

Here, as another method for adjusting the particle size of the object to be crushed, the distance between the pair of impellers 120 can be adjusted. For example, when the impeller 120 is coupled to each other by the rotating shaft beam 140, by providing a screw structure or a sliding composition to the rotating shaft beam 140, by adjusting the position of the impeller 120 from the end of the rotating shaft, one It is possible to adjust the spacing between the vortex surfaces 124a of the pair of impellers 120. Due to this, it is possible to control the wind speed generated between the impellers 120, and thereby, the particle size of the object to be crushed can be adjusted in various ranges.

As shown in FIG. 2A, the protrusion 124c formed on the vortex surface 124a of the wing portion 124 is preferably circular in shape as viewed from the front. That is, by being convexly formed in a part of a spherical shape, the crushing objects flowing in the streamlined protrusions 124c and the crushing objects introduced through the fast flow velocity in the narrow gaps of the vortex surfaces 124a facing each other smoothly. It can be provided to collide.

Here, the pair of impellers 120 is preferably the same shape. That is, the shape of the protrusion 124c and the radially inner and radially outer sides of the protruding portion 124c at the moment when the surfaces of the wing portions 124 coincide when the respective impellers 120 are driven to rotate in opposite directions at positions facing each other. The location of the narrow gap of the vortex surface 124a located is also coincident, so that the shear force acting on the grinding target is uniform. At this time, the wing portion 124 is shown that the four-blade type formed extending in the radially outer four directions from the central portion 122, the number of the wing portion 124 is not limited to this, it may be provided in a 6-blade or 8-blade type have.

Additionally, by forming micro embossing or scratches in the protrusions 124c of the multipurpose grinder according to one embodiment of the present invention or the grooves of the multipurpose grinder according to another embodiment of the present invention, stronger air By inducing the flow, it is possible to increase the grinding efficiency.

In addition, in order to prevent the multi-purpose grinder according to the present invention from being heated, a cooling fan may be provided outside the driving body to cool by air cooling.

On the other hand, in the above-described embodiment, although the food material is described as a crushing object as a reference, the multi-purpose grinder according to the present invention is not only used to crush food materials, but can be used to crush all kinds of crushing objects such as paints. .

All simple modifications or changes of the present invention can be easily carried out by those skilled in the art, and all such modifications or changes can be considered to be included in the scope of the present invention.
