In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Yeast is the earliest and most successful microorganism for human beings and is widely applied to the fields of food fermentation, pharmacy, cosmetics, fertilizers, feeds and the like. The yeast products commonly used at present are fresh yeast, semi-dry yeast, dry yeast and the like. Wherein, the fresh yeast is also called compressed yeast, and is a yeast product which is not dried and granulated, the main component of the fresh yeast is 70% of water, and other solid matters such as yeast are 30%. Fresh yeast is generally produced in the form of cubes, long bars, or pellets. Compared with semi-dry yeast and dry yeast, the fresh yeast has the characteristics of more water, less impurities, high viscosity, more living cells, faster fermentation speed, lower use cost and the like.

When fresh yeast is used, it is often necessary to divide the whole fresh yeast into small pieces so as to be dissolved in the base material and thoroughly mixed with the base material. The current common cutting method is to manually break off the fresh yeast or cut the fresh yeast into small pieces by a cutter after the fresh yeast is thinned. The fresh yeast blocks obtained by manual cutting have different shapes and sizes, and the fresh yeast blocks with different sizes are difficult to be completely dissolved in base materials such as water, flour and the like, so that the fresh yeast and the base materials are unevenly mixed. Moreover, the speed of manually cutting fresh yeast is slower, the efficiency is lower, and the cutting requirement when a large amount of fresh yeast is used is difficult to meet.

As shown in fig. 1, 7 and 8, in order to solve the technical problems of uneven dicing and low dicing efficiency when fresh yeast is diced, the utility model provides a fresh yeast dicing device, which comprises a cavity 1, a material injection structure 2 and a dicing structure 3, wherein a molding hole 11 is arranged on the cavity 1, one end of the molding hole 11 is communicated with the inner side of the cavity 1, the other end of the molding hole 11 is communicated with the outside of the cavity 1, the material injection structure 2 comprises a feeding hole 21, a material injection piece 22 and a material injection hole 23, the material injection hole 23 is communicated with the inner side of the cavity 1, the material injection piece 22 is used for conveying materials from the feeding hole 21 to the material injection hole 23, the dicing structure 3 comprises a cutter 31, the cutter 31 is positioned on the outer side of the cavity 1, and the cutter 31 can reciprocate relative to the molding hole 11 so as to cut the materials extending out of the molding hole 11.

The cavity 1 is a carrier body with a cavity inside for containing and carrying materials. The cavity in the cavity 1 is used for containing and bearing the injected fresh yeast; when the fresh yeast is injected into the cavity 1, the fresh yeast has a certain pressure, and in order to prevent the cavity 1 from being damaged, the cavity 1 has a certain pressure-resistant structure, such as a thicker cavity wall thickness, pressure-resistant reinforcing ribs and the like, so as to cope with the pressure of the fresh yeast on the cavity 1.

The shaping hole 11 is specifically disposed on the bottom wall of the cavity 1, one end of the shaping hole 11 is communicated with the inner side of the cavity 1, and the other end is communicated with the outside of the cavity 1. After the fresh yeast is injected into the cavity 1, the fresh yeast can be extruded out of the cavity 1 through the forming hole 11, and the fresh yeast outside the extruded cavity 1 is shaped under the forming action of the forming hole 11, namely, the cross-sectional shape of the forming hole 11 determines the cross-sectional shape of the fresh yeast outside the extruded cavity 1. By changing the extrusion shape of the fresh yeast, the specific surface area of the extruded fresh yeast can be changed, thereby improving the dissolution rate of the fresh yeast. In order to improve the cutting efficiency of the fresh yeast, the number of the molding holes 11 can be multiple, and the molding holes 11 are uniformly arranged on the bottom cavity wall of the cavity 1 in an array mode; in order to ensure that the shape and the size of the cut fresh yeast pieces are consistent and the dissolution rate is consistent, the cross-sectional shape and the cross-sectional size of each molding hole 11 are also consistent.

The material injecting structure 2 is a structure for injecting fresh yeast into the cavity 1. The finished fresh yeast to be cut is sent into the material injection structure 2 through the feeding hole 21, and the material injection piece 22 conveys the fresh yeast from the feeding hole 21 to the material injection hole 23 through the actions of extrusion, traction and the like and injects the fresh yeast into the cavity 1 through the material injection hole 23. In the material injection structure 2, the pressure of the fresh yeast is applied by virtue of the extrusion or traction action of the material injection piece 22 on the fresh yeast, and the fresh yeast enters the cavity 1 and is extruded from the forming hole 11 under the extrusion or traction action of the material injection piece 22.

The cutting structure 3 is used for cutting the fresh yeast in the extrusion molding hole 11, so that cut fresh yeast blocks are obtained. The cutter 31 in the cutting structure 3 reciprocates with respect to the molding hole 11 at a certain period to cut the fresh yeast protruding from the molding hole 11. The reciprocating motion of the cutter 31 may be specifically the reciprocating motion of the cutter 31 along the linear direction, which is suitable for the case that each molding hole 11 is in a square array; or the rotary motion of the cutter 31 in the circumferential direction, is suitable for the case where each molding hole 11 is in an original array. Under the cutting action of the cutter 31, the whole fresh yeast is cut into uniform small fresh yeast blocks, and the shape of the fresh yeast blocks can be cut into fresh yeast blocks in the shape of slices, blocks or strips according to the section shape of the forming hole 11, the movement period of the cutter 31 and the extrusion speed of the fresh yeast.

Compared with the traditional fresh yeast cutting mode, the fresh yeast cutting device provided by the utility model has the advantages that fresh yeast is injected into the cavity 1 through the material injection structure 2, the fresh yeast is cut into fresh yeast blocks with uniform size and uniform shape under the cutting action of the forming holes 11 and the cutting structures 3 of the cavity 1, and the fresh yeast cutting device does not need manual breaking or cutting, and has the advantages of high cutting efficiency, convenience in use and the like.

It should be noted that the fresh yeast cutting device of the present utility model is only one of many ways of using fresh yeast, and the fresh yeast cutting device of the present utility model may also be used for cutting other materials, such as dough, molten rubber, etc.

As shown in fig. 4 and 5, in one embodiment of the present utility model, the injection structure 2 includes an injection cavity 24 and a first driving member 25, where the feed inlet 21 and the injection inlet 23 are both disposed on the injection cavity 24, and the injection member 22 is movably connected in the injection cavity 24, and the first driving member 25 is in driving connection with the injection member 22.

The filling chamber 24 is an internal vacuum chamber for holding material (fresh yeast) and for loading the filling 22. The injection member 22 cooperates with the inner wall of the injection cavity 24 to form a space in which fresh yeast can be squeezed or pulled. The first driving member 25 may be a motor, a hydraulic cylinder, an electric push rod, etc., and the first driving member 25 drives the material injecting member 22 to work in the material injecting cavity 24. The injection member 22 is movably connected to the injection cavity 24, specifically, the injection member 22 may be rotatably connected to the injection cavity 24, or the injection member 22 may be movably connected to the injection cavity 24 along the direction from the feed inlet 21 to the injection inlet 23.

In one embodiment of the present utility model, as shown in fig. 4 and 5, the injection member 22 is a screw, the screw is rotatably connected in the injection cavity 24, the feed port 21 is located at one end of the screw, the injection port 23 is located at the other end of the screw, and the first driving member 25 is in driving connection with the screw.

The first driving member 25 may be an electric motor, a hydraulic motor, or the like. The rotation of the screw is driven by the first driving member 25. When the screw rotates, the rotation axial direction of the screw is consistent with the axial direction/length direction/material injection direction of the material injection cavity 24, and the screw can be matched with the inner wall of the material injection cavity 24 to form a screw conveying mechanism. Fresh yeast is rolled into a space formed by closing the screw and the inner wall of the material injection cavity 24 through rotation of the screw, and is continuously pulled and pushed towards the material injection opening 23 along with rotation of the screw. The number of screws may be single screw or twin screw, etc. in order to increase the injection pressure of the injection port 23.

In another embodiment of the present utility model, the injection member 22 may be a piston (not shown) movably connected in the injection cavity 24 along the direction from the feed port 21 to the injection port 23, and the first driving member 25 drives the piston to reciprocate in the injection cavity 24 along the direction from the feed port 21 to the injection port 23.

The first driving member 25 may be an electric push rod or a hydraulic/pneumatic cylinder. In operation, the piston extrudes fresh yeast in the feed port 21 towards the direction of the injection port 23, so that the fresh yeast is injected into the cavity 1 through the injection port 23.

As shown in fig. 4, in one embodiment of the present utility model, the cross-sectional shape of the cavity 1 is circular, and the injection direction of the injection port 23 is arranged in a tangential direction of the circular shape.

When the cross-sectional shape of the cavity 1 is circular, the cavity 1 may be a cylindrical cavity, a conical cavity, a truncated cone cavity, or a spherical cavity. In the case of any of the above-mentioned shapes of the cavity 1, the molding holes 11 are preferably provided on the bottom cavity wall of the cavity 1 so that the fresh yeast is extruded and falls down by its own weight.

The inventors found during development that, when fresh yeast is extruded, the extrusion pressure is higher at a position inside the cavity 1 closer to the injection port 23, and lower at a position farther from the injection port 23. If the relation between the extrusion pressure of the fresh yeast and the position of the injection port 23 is not taken into consideration, the problem of uneven extrusion pressure of the fresh yeast and uneven extrusion size of the fresh yeast at each molding hole 11 is easily caused. Therefore, the injection direction of the injection port 23 is arranged along the tangential direction of the circular section of the cavity 1, so that fresh yeast can be injected into the cavity 1 along the tangential direction of the cavity 1, and when the fresh yeast continues to move towards the inside of the cavity 1, the pressure is gradually and uniformly dispersed to the peripheral fresh yeast, so that the extrusion pressure of the fresh yeast at each forming hole 11 is uniform, and the consistency of the extrusion size of the fresh yeast is improved.

In one embodiment of the present utility model, as shown in fig. 4 and 9, the shaped aperture 11 is a long narrow aperture.

Where long narrow holes refer to holes having a width dimension that is smaller or much smaller than a length dimension. When fresh yeast passes through the long narrow holes, the fresh yeast is extruded into thin flake fresh yeast with smaller thickness. Compared with columnar fresh yeast, bar-shaped fresh yeast and the like, the flake-shaped fresh yeast has larger specific surface area, larger contact area with the base material, and is easier to break into smaller fresh yeast particles when being stirred and mixed with the base material, the dissolution speed of the flake-shaped fresh yeast is faster, and the flake-shaped fresh yeast is easier to be uniformly mixed with the base material. The specific surface area refers to the total area of the materials in unit mass, namely, the larger the body surface area is, the larger the specific surface area is when the mass is fixed; alternatively, the smaller the mass, the larger the specific surface area, at a given body surface area. The larger the specific surface area is, the higher the dissolution activity is, and the material is easier to be mixed with the base material uniformly.

In one embodiment of the utility model, the cross-sectional shape of the long and narrow holes may be arc-shaped, wave-shaped, etc., so that the flake-shaped fresh yeast has a larger specific surface area.

In one embodiment of the utility model, as shown in fig. 7 and 8, the cutting structure 3 comprises a second driving member 32 and a blade holder 33, the second driving member 32 being drivingly connected to the blade holder 33, and the cutter 31 being connected to the blade holder 33.

The second driving member 32 may be an electric motor, a hydraulic motor, or the like. The tool holder 33 is rotatably connected to the cavity 1 or to an external base. The second driving member 32 and the tool holder 33 drive the tool holder 33 by means of gear transmission, belt transmission, chain transmission and the like. The second drive member 32 is preferably in geared connection with the tool holder 33 in the present utility model. By setting the gear ratio of the gear transmission, the higher rotation speed of the second driving member 32 is output as the lower working rotation speed of the tool holder 33, and the rotation speed range of the tool holder 33 is generally 100-500r/min. The cutter 31 is connected to the cutter holder 33 along the circumferential direction, and the cutter 31 is driven to cut the fresh yeast in the extrusion molding hole 11 by the rotation of the cutter holder 33.

In another embodiment of the present utility model, the second driving member 32 may also be an electric push rod, a pneumatic/hydraulic cylinder, or the like. The second driving piece 32 drives the tool apron 33 to reciprocate along the linear direction, so that the cutter 31 is driven to cut the fresh yeast in the extrusion molding hole 11.

The inventor finds that if the cut fresh yeast blocks cannot be stirred and mixed with the base material in time in the research and development process, the fresh yeast blocks are easy to bond and fuse together. Therefore, the inventors thought to add a stirring device 4 to the fresh yeast cut device so that the cut fresh yeast pieces can be immediately put into the base material for stirring and mixing.

As shown in fig. 6 to 8, in one embodiment of the present utility model, the fresh yeast cutting apparatus further includes a stirring device 4, the stirring device 4 includes a stirring shaft 41 and a stirring member 42 connected to the stirring shaft 41, and the stirring shaft 41 is drivingly connected to the second driving member 32.

Wherein the stirring device 4 is a device for stirring the base material and the yeast block. Fresh yeast extruded from the fresh yeast molding hole 11 is cut into yeast blocks by the cutter 31, and then falls into the stirring barrel 7 by the self weight of the yeast blocks, and the yeast blocks and the base materials in the stirring barrel 7 are mixed and stirred by the stirring device 4. And the stirring piece 42 is driven to move by the stirring shaft 41, so that the mixing and stirring of the base material and the saccharomycete blocks are realized. The stirring member 42 may be a stirring blade, a stirring rod, or the like. The number of stirring members 42 may be plural in order to improve the stirring efficiency of the stirring members 42.

The inventors have, during development, in view of the problems of saving production costs and improving the compactness of the apparatus, drivingly connected the stirring shaft 41 to the second driving member 32. The stirring shaft 41 is driven to operate by the output of the driving force from the second driving member 32. Specifically, the second driving member 32 drives the stirring shaft 41 by means of gear transmission, belt transmission, chain transmission, or the like, and the second driving member 32 is driven by the stirring shaft 41. In order to operate the stirring shaft 41 at a predetermined rotational speed, the stirring shaft 41 is preferably in geared connection with the second drive 32. By setting the gear ratio of the gear transmission, the higher rotation speed of the second driving member 32 is output as the lower working rotation speed of the stirring shaft 41, and the rotation speed of the stirring shaft 41 is generally 20-200r/min.

When the second driving member 32 simultaneously drives the blade holder 33 and the stirring shaft 41, the rotation axis of the blade holder 33 and the rotation axis of the stirring shaft 41 may be arranged in a staggered manner to prevent the blade holder 33 and the stirring shaft 41 from interfering with each other; the compactness of the fresh yeast cutting device can be enhanced by adding the transmission shaft 43 to enable the cutter holder 33 to be arranged coaxially with the stirring shaft 41. As shown in fig. 8 and 10, in one embodiment of the present utility model, the stirring device 4 further includes a driving shaft 43, one end of the driving shaft 43 is drivingly connected to the second driving member 32, and the other end of the driving shaft 43 is detachably connected to the stirring shaft 41.

The second drive member 32 is preferably in geared connection with the drive shaft 43 in the present utility model. By setting the gear ratio of the gear transmission, the higher rotational speed of the second driving member 32 is output as the lower rotational speed of the driving shaft 43, and the rotational speed of the driving shaft 43 is generally in the range of 20-200r/min. In order to enable the tool holder 33 and the transmission shaft 43 to be coaxially arranged, the tool holder 33 is preferably a hollow tool holder, the cutter 31 is connected to the outer side of the hollow tool holder along the circumferential direction, the hollow tool holder is sleeved on the transmission shaft 43, and the transmission shaft 43 penetrates through the hollow tool holder. The drive shaft 43 and the hollow seat are connected by a bearing bush, bearing or the like to reduce friction therebetween, so that the seat 33 and the drive shaft 43 can be coaxially disposed and move without interference with each other.

As shown in fig. 11 and 12, in one embodiment of the present utility model, a clamping groove 431 is formed on the transmission shaft 43, a protrusion 411 is formed on the stirring shaft 41, and when the transmission shaft 43 is connected to the stirring shaft 41, the protrusion 411 is inserted into the clamping groove 431.

The clamping groove 431 is arranged on the transmission shaft 43 in a U-shaped bending mode. The first end of the clamping groove 431 is an open end for inserting the protrusion 411; the second end of the locking groove 431 is a closed end for mounting the protrusion 411. Specifically, the clamping groove 431 is sequentially provided with an insertion section, a connection section and a mounting section. The opening end is located the insert section, and the linkage segment is used for communicating insert section and mount section, and the bottom of mount section is located to the closed end, and the bottom of mount section is less than the linkage segment setting. The protrusions 411 are protrusions/projections provided on the stirring shaft 41 in the radial direction of the stirring shaft 41. In use, the projection 411 is inserted into the insertion section from the open end and falls into the mounting section after passing through the connection section. At this time, the locking groove 431 plays a limiting role in the axial direction and the radial direction of the stirring shaft 41, so that the transmission shaft 43 can drive the stirring shaft 41 to rotate.

In another embodiment of the present utility model, the clamping groove 431 may be disposed on the stirring shaft 41, and the protrusion 411 is disposed on the transmission shaft 43.

As shown in fig. 8 and 10, in one embodiment of the present utility model, the stirring device 4 further includes a limiting structure 5, where the limiting structure 5 includes an elastic member 51 and a stopping member 52, one end of the elastic member 51 is connected to the transmission shaft 43, the other end of the elastic member 51 is connected to the stopping member 52, and when the protrusion 411 is connected to the locking groove 431 in a plugging manner, the stopping member 52 is stopped against the protrusion 411.

The limiting structure 5 is a structure for limiting the connection position of the protrusion 411 and the locking groove 431, that is, a structure for limiting the connection position of the transmission shaft 43 and the stirring shaft 41. Both ends of the elastic member 51 are connected to the transmission shaft 43 and the stopper 52, respectively, so that the stopper 52 can elastically expand and contract with respect to the transmission shaft 43. The elastic member 51 of the present utility model may be a spring or a leaf spring. Elastic tubing, etc. The stopper 52 is specifically a stopper sleeve, stopper block, or the like. When the stirring shaft 41 is in operation, the material impacts the stirring element 42 and the stirring shaft 41, thereby generating vibrations on the stirring shaft 41 which may force the protrusion 411 to separate from the catch 431, thereby causing the transmission shaft 43 to disengage from the stirring shaft 41. Therefore, the stopper 52 elastically abuts against the protrusion 411, so that the elastic expansion and contraction of the stopper 52 can absorb the vibration energy on the stirring shaft 41 to buffer the stirring shaft 41, and can limit the protrusion 411 to the locking groove 431 to prevent the protrusion 411 from being separated from the locking groove 431.

As shown in fig. 2 and 3, in one embodiment of the present utility model, the fresh yeast slitting device further includes a supporting frame 6. The supporting frame 6 is a supporting carrier of the cavity 1, the material injection structure 2, the stirring barrel 7 and other parts, and plays a role in supporting and positioning.
