Description

Technical Field

[0001] The present invention relates to the technical field of koji, and in particular to a koji processing device and method. Background Art

[0002] Yeast is a microorganism created by introducing a fermentation strain (aspergillus or yeast) into a strongly steamed raw material (rice or barley). The strain is then incubated under heat preservation conditions, allowing mycelium to grow on the raw material. This mycelium produces amylase, which breaks down the starch in the raw material into fermentable sugars. This mycelium is called koji. During the koji processing process, the raw material is steamed and then mixed with the appropriate bacterial strain to ensure thorough mixing of the raw material and the bacterial strain, facilitating subsequent fermentation.

[0003] Referring to a stirring device for koji production and processing with Chinese patent publication number CN213348440U, a threaded rod is provided. When cleaning is required, the control panel is adjusted so that the electric push rod drives the limit block to be pulled to the right, thereby separating the limit block from the threaded rod. At this time, the threaded rod will rotate under the drive of the servo motor. Since there are two opposite threads on the threaded rod, the two movable rings are moved away from each other. While the stirring rod rotates, it pushes the scraper to move until the scraper contacts its inner wall. Then the electric push rod pushes the limit block to fix the threaded rod, and then the driving motor drives the scraper to scrape off the attached debris, thereby achieving the effect of easy cleaning. The entire cleaning process is relatively simple, the cleaning efficiency is improved, and the cleaning is more thorough, which is convenient for promotion and use.

[0004] Referring to a uniform mixing device for the production and processing of fruit wine koji with Chinese patent publication number CN213132958U, by starting the stirring motor, the stirring motor drives the stirring paddle and the lifting paddle to rotate through the output shaft and the drive shaft. During the rotation, the stirring paddle stirs and mixes the fruit wine koji inside the chassis horizontally, and the lifting paddle rotates at high speed and cooperates with the cylinder to lift and stir the fruit wine koji at the bottom of the chassis. Finally, by starting the drive motor, the drive motor drives the crankshaft to rotate through the output shaft, and the crankshaft drives the turntable and the rotating shaft to reciprocate through the connecting rod and the pin rod. The rotating shaft drives the chassis to swing back and forth and accelerates the mixing efficiency of the fruit wine koji inside the chassis, achieving a simple and convenient multi-stage mixing effect, thereby improving the processing efficiency of the mixing device.

[0005] In the prior art koji mixing process, a stirring device is generally used to pour the cooked rice or barley and the bacterial strain into a fermentation tank for stirring. Since the rice or barley is in a wet and sticky state after the cooking process, the bacterial strain is very likely to concentrate in a local area of ​​the fermentation tank, resulting in the formation of koji balls or raw material balls with the rice or barley and being unable to be fully stirred, causing part of the rice to not be inoculated with enough bacterial strains, which may affect the fermentation effect and the consistency of the fermentation time. For example, in a stirring device for koji production and processing with reference to patent publication number CN213348440U, the koji raw materials and bacterial strains can only be put into the shell through a feed pipe, and the bacterial strains cannot be evenly dispersed on the surface of the rice, requiring longer stirring. Stirring time and greater stirring force can meet the requirements of uniform mixing of bacteria and rice; secondly, longer stirring time or greater stirring intensity can achieve uniform mixing of bacteria and rice or barley, but high stirring intensity and long time will destroy the cell structure of the bacteria and affect the number and activity of the bacteria. For example, a uniform mixing device for the production and processing of fruit wine koji with reference patent publication number CN213132958U has a chassis that flips while the stirring paddle stirs. The strong stirring force can easily lead to a decrease in the activity of the internal bacteria of the wine koji, affecting the fermentation time in the subsequent winemaking process.

[0006] To this end, the present invention proposes a koji processing device and method to solve the above problems. Summary of the Invention

[0027] The present invention provides a koji processing device and method. Compared with the prior art, it has the following advantages:

[0028] 1. A koji processing device and method, comprising a fermentation tank assembly including a fermentation cylinder, a sealing cover, a discharge port, a sealing plate, and a feeding hopper, wherein the sealing cover is detachably mounted on the top of the fermentation cylinder, and a koji raw material filling port is provided on the top of the sealing cover, a sealing plug is detachably mounted inside the raw material filling port, the discharge port is located below the outer wall of the fermentation cylinder for discharging fermented koji, the sealing plate is rotatably connected to the inside of the discharge port, and is used to seal the discharge port to prevent external air from entering, the feeding hopper is fixedly mounted on the outer wall of the fermentation cylinder, a strain feeding mechanism for feeding koji strains is provided inside the fermentation cylinder, and the strains are A mixing mechanism for mixing the koji raw materials and the koji strains is provided below the feeding mechanism, and a servo motor for providing power to the strain feeding mechanism and the mixing mechanism is provided on the top of the support frame, which solves the problem that the koji raw materials are in a wet and sticky state after steaming, and the strains are easily concentrated in local areas of the fermentation tank, resulting in the easy formation of koji balls or raw material balls with the koji raw materials and inability to be fully stirred, causing some rice to not be inoculated with enough strains, which may affect the fermentation effect and the consistency of the fermentation time, and longer stirring or higher stirring intensity will destroy the cell structure of the strains, affecting the number and activity of the strains.

[0029] 2. A koji processing device and method, which can use a first auger to stir the koji raw material in the mixing mechanism while conveying the koji raw material toward the fungus feeding mechanism by setting a koji raw material conveying component, so that the koji raw material is close to the fungus feeding mechanism, which facilitates the fungus to be evenly sprinkled on the surface of the koji raw material; secondly, the koji raw material is blocked by the upper conical disk during the upward conveyance, and is continuously pushed by the upward conveyed koji raw material, so that the koji raw material forms a flat structure between the upper conical disk and the lower conical disk, and slides to all sides along the surface of the lower conical disk at the same time, thereby increasing the area of ​​the koji raw material for receiving the fungus. , so that the bacteria can be distributed on the surface of the koji raw material to the maximum extent during the spreading process, avoiding the concentrated distribution of the bacteria, which is conducive to the subsequent sufficient mixing of the koji and the bacteria; furthermore, by setting up multiple scrapers, the koji raw material can be cut when it slides along the gap between the upper conical disk and the lower conical disk, so that it forms multiple independent block structures, which is convenient for the bacteria raw material to slide from the surface of the lower conical disk into the fermentation cylinder, and after the fermentation of the koji is completed, the electric motor can be used to drive the scraper to rotate, so as to achieve the purpose of scraping off the residual impurities on the opposite side walls of the upper conical disk and the lower conical disk, which is conducive to the next processing operation of the koji.

[0033] 6. A koji processing device and method, which uses the same servo motor to provide power for a mixing mechanism and a strain feeding mechanism, and can simultaneously achieve the purpose of strain spreading and mixing the strain and koji raw materials. There is no need to set up multiple power devices, saving the cost of setting up power devices, which is conducive to the large-scale promotion and use of the present invention.

[0055] The embodiment of the present invention further provides a method for processing a koji processing device, the specific method comprising the following steps:

[0056] Step 1: Raw material cleaning: First, put the koji raw materials into the cleaning machine for cleaning to remove impurities and unclean substances;

[0057] Step 2: Soaking: Place the cleaned koji raw materials into a large vat or sink for soaking to soften the grains and promote the release of enzymes;

[0058] Step 3: Steaming: Place the soaked koji raw materials into the steamer and cook until the internal temperature of the grains reaches 70-80 degrees Celsius;

[0059] Step 4: Cooling: Place the cooked koji raw materials in a ventilated place to cool until the temperature drops to a range suitable for fermentation;

[0060] Step 5: Mix the cooled koji with the bacteria to ensure full contact between the koji and the bacteria and promote the fermentation process.

[0061] Step 6: Fermentation: Place the mixed koji into a fermentation tank and ferment under suitable temperature and humidity conditions;

[0062] Step 7: Drying: After fermentation is complete, take out the koji and dry it until the moisture content reaches a certain standard;

[0063] Step 8: Packaging: The dried koji is screened, packaged, and sealed to obtain the finished koji for subsequent use.

[0064] In the step 1, the koji raw material is barley or rice, and in the step 5, the corresponding inoculated strain is yeast or Aspergillus.

[0065] During use, the cooked rice or barley is added to the fermentation cylinder 2 through the koji raw material filling port on the top side of the sealing cover 3, and then the bacterial strain particles of the corresponding koji raw materials are added to the feeding hopper 6 in proportion according to the amount of koji raw materials added in the fermentation cylinder 2.

After the spawn is added, To prevent the koji raw materials from entering the first cylinder 71, the koji raw materials then enter the first cylinder 71 through the feed port 842 and are transported upward along the first cylinder 71 under the action of the first auger 72. During the upward transportation of the koji raw materials, they are blocked by the upper conical disk 74 and are continuously pushed by the upwardly transported koji raw materials, so that the koji raw materials form a flat structure between the upper conical disk 74 and the lower conical disk 73, and slide around along the surface of the lower conical disk 73. At the same time, the first transmission shaft 710 rotates while driving the driving arm 7117 to rotate. Since the driving arm 7117 includes an annular sleeve and a driving rod evenly fixedly connected to the outer wall of the annular sleeve and a driving rod fixedly connected to the bottom of the driving rod The driving block and the driving rod drive the driving block to intermittently push the protrusion 7116 downward, and the upper baffle 7115 uses the connecting rod 7114 to push the lower baffle 7113 downward, and the lower baffle 7113 and the annular discharge port are separated, so that the bacteria can be sprinkled from the bacteria storage cylinder 7111. When the driving rod and the protrusion 7116 are separated, the spring 7119 pushes the lower baffle 7113 to return to its original position, and the annular discharge port is blocked, and the bacteria cannot fall. Since the driving arm 7117 rotates at a high speed, the lifting speed of the lower baffle 7113 is fast, which can realize the continuous release of bacteria. The bacteria can be distributed on the surface of the wine yeast raw material to the maximum extent during the throwing process. After the wine yeast fermentation is completed, the fermented wine yeast is taken out through the discharge port 4;Next, to clean the spawn delivery mechanism 7, the electric motor 78 is activated to rotate the first gear 79. Since the first gear 79 is meshed with the gear ring 76, the rotation of the gear ring 76 drives the collar 75 and the scraper 77 to rotate, thereby scraping away any impurities remaining on the opposing side walls of the upper and lower conical disks 74 and 73, thereby keeping the upper and lower conical disks 74 and 73 clean.
