Description

Technical Field

[0001] The invention relates to the technical field of brewing, in particular to a molding device for brewing koji blocks. Background Art

[0002] In the wine making process, one of the important steps is koji making. The so-called koji making is to mix the raw materials (wheat, barley, peas, etc.) for making koji blocks according to the proportion. After the raw materials are treated with impurities, they are moistened and crushed. The amount of water added to the crushed koji is determined according to the calculated ratio. After the koji and water are mixed evenly, they are pressed into koji blocks by the koji making device and enter the next bacterial culture process. The traditional koji making process is to place the koji in a mold and have people of appropriate weight step on it manually. The koji in the mold is stepped on repeatedly by the soles of the feet to gradually make the koji tissue uniform and change from loose to dense, and finally form koji blocks through the briquetting process. The advantage of this traditional method is that during the repeated stepping of the koji by the soles of the feet, the koji is fully uniformed and the internal density is consistent with the effect of kneading dough, which is conducive to the uniform growth of microorganisms in the subsequent koji block culture, and effectively reduces the consistency deviation of koji block culture. Although manual koji pressing has many advantages, low production efficiency is an inevitable defect. Therefore, the modern wine industry currently uses mechanical koji making devices to produce koji blocks. The mechanical koji making device presses the molded koji material on the production line several times to compact it into koji blocks, and then sends the formed koji blocks to the culture chamber for the culture process. Ordinary mechanical koji making devices have the advantages of high efficiency and low cost, but the uniformity of the internal koji material and the consistency of the tightness and density of the pressed koji blocks are not as good as those of manual koji pressing, which easily leads to large fluctuations in the culture quality of the koji blocks.

[0003] The patent document with application number CN202010549752.9 and name “A koji briquetting machine” in the Chinese patent database discloses a technical solution, which is provided with a plurality of evenly distributed rectangular mold frames for holding koji bulk materials on the conveying mechanism, the rectangular mold frame is movably connected with a conveying mechanism, a bottom plate is provided above the frame, the bottom plate and the rectangular mold frame form a semi-sealed structure, a limited position table is provided on the inner side above the frame, a feed port is provided above the feeding end of the conveying mechanism, a scraping mechanism for scraping the koji bulk materials in the rectangular mold frame is provided on the left side of the feed port, and a pressing roller for compacting the koji bulk materials is provided on the left side of the scraping mechanism. The utility model is simple to operate, but the compaction density of the koji blocks produced by it is low, and the shape of the koji blocks is a rectangular parallelepiped, and the six outer surfaces are all planes, with less contact area with the surrounding air, and low bacterial cultivation efficiency. If the geometric shape of the surface of part of the koji block can be changed without increasing the production cost, the area of ​​contact between the koji block and the air during the bacterial cultivation process can be increased, thereby improving the bacterial cultivation efficiency.

DETAILED DESCRIPTION

[0017] See also Figure 1 The molding device of the brewing koji block of the present invention comprises a molding part, a koji stepping part and a conveyor belt. The conveyor belt is divided into a feeding conveyor belt 1, a discharging conveyor belt 2 and a molding conveyor belt 3. Different from the prior art in which the koji material is pressed by manual koji stepping or machine pressing, the present invention feeds the lower mold 7 containing the koji material into the koji stepping part, and the koji material is subjected to a stepping treatment similar to repeated dough kneading operation by a stepping mechanism, so that each part of the koji material forms a well-uniformed and highly consistent koji material; then the stepped and pressed koji block mold is transported to the molding part via a conveyor belt, and the koji material is compacted by a molding cylinder to form a koji block of a predetermined shape, which is then output to the koji block collection station by a conveyor belt.

[0018] See also Figure 1-Figure 3 The profiling part of the present invention is provided with a profiling platform 4, the profiling platform supports the conveyor belt, a profiling cylinder 5 is provided on the upper part of the profiling part, and the piston rod of the profiling cylinder is connected to the upper mold 6. After the mold enters the predetermined position, the conveyor belt stops moving, and the upper mold presses and shapes the curved material in the curved block mold under the action of the profiling cylinder to press out a curved block with a predetermined shape and strength. The profiling surface of the profiling upper mold is an arc-shaped profiling surface or a wavy surface. The upper surface of the curved block after profiling is an outwardly convex arc surface, or a plurality of hemispherical wavy surfaces evenly arranged, such as Figure 4 The more hemispherical surfaces there are, the more the total area of ​​the upper surface of the koji block can be increased, thereby increasing the area of ​​the koji block in contact with the air during the bacterial cultivation process and improving the bacterial cultivation efficiency.

[0019] The present invention is provided with a push cylinder 8 for introducing the lower die 7 from the feeding conveyor 1 to the pressing conveyor 3. The present invention is also provided with a discharging mechanism for introducing the finished curved block together with the lower die 7 to the next process, and this function is performed by the discharging mechanism.

[0020] The discharging mechanism is symmetrically arranged in two sets, which are respectively arranged on both sides of the pressing conveyor belt 3; the discharging mechanism is provided with a mold driving motor 10, a lead screw 12 and a nut 11, and an electromagnet 13 is provided on the nut. The electromagnetic suction force generated by the electromagnet 13 is sufficient to pull the lower mold 7 to move, and the lead screw and the nut form a threaded pair. The lead screw is connected to the mold driving motor 10, and two slide rails 14 are fixed in parallel on the frame. One side of the nut is slidably matched with the slide rail, so that the nut can move freely along the track and smoothly attract the lower mold 7 to enter the discharging process.

[0021] Of course, longer screws and rails can also be set to switch between feeding the curved material and delivering the curved blocks.

[0022] See also Figure 5-Figure 7 The stepping part of the present invention includes a stepping mechanism for stepping and kneading the bent material, a limiting mechanism for limiting the movement of the stepping column, and a stepping platform 15. The stepping part imitates the process of an artificial foot stepping on the bent material, wherein the stepping mechanism is arranged on the upper part of the stepping platform 15, and the stepping mechanism is provided with a stepping drive motor 18, a main shaft 25, a cam 27, a cam mounting plate 26, a stepping column 23 and a bionic foot mold 16. The pillars on both sides support the stepping mechanism, and the bottom thereof is fixed to the frame, and the stepping drive motor is installed on the platform above the pillar 22. The stepping drive motor drives the main shaft to rotate, and several cam groups are installed in parallel on the main shaft, Figure 4 As shown, two cam groups are used, each cam group is provided with two cams, the convex parts of the two cams are installed in different orientations, and the lower part of each cam corresponds to the top of a stepping column. In this way, when a group of cams rotates with the main shaft, the convex parts of the two cams are alternately pressed on the top of the stepping column, and the stepping column drives the bionic foot mold 16 to step on the curved material alternately, just like a human foot alternately steps on the curved material. A cam mounting plate 15 is provided on one side of the cam, and the cam mounting plate is fixed on the main shaft. The adjacent cams are axially limited by a spacer 17. The cam mounting plate is provided with screw holes at intervals along the circumferential direction. The cam is fixed to the cam mounting plate by screws, and the installation angle of the cam can be changed as needed. Figure 6 The installation angles of the two cams are staggered by 90 degrees, and each cam is symmetrically provided with two raised parts. When the main shaft rotates one circle, each cam presses down the pressure column twice.

[0023] See also Figure 7 The bionic foot model 16 includes a foot-like body 16-1 and an elastic sleeve 16-2. The foot-like body 16-1 is a foot-like body made of a relatively hard elastic material, slightly concave in the middle, and drooping arcs at both ends, similar to the shape of a human foot. The elastic sleeve 16-2 is made of an elastic material slightly softer than the foot-like body, and is wrapped around the foot-like body 16-1; the bionic foot model 16 is connected to the lower part of the stepping column 23 by a flange.

[0024] The bionic foot model 16 of the present invention has a certain elasticity, and its purpose is to simulate the natural swing and flexion and extension of the toes during the stepping process, so that the curved material can be stepped on more carefully. When the bionic foot model steps on the curved material, the convex part forms a strong step on the curved material, and the concave sole part can form a buffer part for the curved material. Under the action of the stepping pressure on both sides, the curved material is transferred to the sole part. In the continuous shifting and stepping process, the local displacement of the curved material realizes the uniformity of the internal density of the curved material, avoids local excessive hardening, and is conducive to the consistency of the density of the internal curved material. The sum of the width dimensions of all bionic foot models matches the width dimension of the curved block mold, so that a row of bionic foot models can cover the width of the curved block mold, effectively improving the stepping work efficiency.

[0025] See also Figure 5 In order to ensure the smooth movement of the stepping column, a stepping column limiting mechanism is provided. The stepping column limiting mechanism is provided with a set of limiting sleeves 19, each limiting sleeve is connected by a crossbeam 9, and each limiting sleeve is respectively sleeved on the middle part of the stepping column and forms a sliding fit with the stepping column. The crossbeam adjustment sleeve 21 is sleeved on the pillar 22, and locking nuts 20 are respectively provided on the upper and lower parts of the crossbeam adjustment sleeve. By loosening the locking nuts, the height of each limiting sleeve can be adjusted, and the position of the limiting sleeve is fixed by the locking screw 20 after the position is determined. A touch pressure head 28 is provided on the top of the stepping column, and a ball is installed on the touch pressure head to reduce unnecessary friction between the two.

[0026] Still viewing Figure 4 A spring 12 and an adjusting nut 13 are mounted in the middle of the pressure column, and the upper and lower ends of the spring respectively contact the adjusting nut and the limit sleeve. The spring tension can be adjusted by rotating the adjusting nut or adjusting the position of the limit sleeve to obtain a suitable pedaling force.
