Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wine making, in particular to a multifunctional koji inoculating machine. Background Art
[0002] Chinese liquor culture has a history of thousands of years. To this day, liquor brewing is still flourishing all over the country. The basic process of liquor brewing is: raw materials, fermentation, and distillation. Among the three steps of brewing, the most critical is the second step - koji making and fermentation. The solid-state fermentation method is a brewing method that uses natural microorganisms for inoculation, koji making, solid-state saccharification and fermentation, and solid-state retort distillation. It uses sorghum, wheat, rice, corn, etc. as raw materials, and uses solid-state matrix form to produce liquor in the main brewing processes such as cooking, saccharification, fermentation, and distillation.
[0003] The production process of red yeast rice, black red yeast rice, and soybean yeast rice is as follows: select raw materials, soak, wash, drain, steam, cool, inoculate, and cultivate flowers [bacteria propagation], then pour it into the ground for cultivation, or cultivate it in a bamboo dustpan, or cultivate it in a ventilation pool, and grow mycelium. It must go through the processes of heating, stirring and cooling, and drinking water many times before it can be cultivated, dried and packaged. Every link must be controlled well and there must be no mistakes to ensure the quality, which is quite difficult. In particular, the rice for making red yeast rice and black red yeast rice requires early indica rice, high hardness, washed rice, short soaking time, water absorption should not exceed about 120%, the steaming time should not be too long, the rice should not be steamed too cooked or rotten, the rice yield should not exceed 130%, and the rice grains should be spread out and not stick together. It is best to let the bacteria cover the surface of each grain of rice, which is the basis for making high-quality koji. From ancient times to the present, the production of red yeast rice, black-clothed red yeast rice, and yellow-clothed red yeast rice is still a manual operation, from soaking rice, washing rice, draining, manually pouring it into the rice steamer to steam, pouring it on the ground after steaming, or blowing it on a flat workbench and stirring it with both hands. Large-scale factories also use a shovel to shovel it into the mixer for inoculation, which is time-consuming, labor-intensive and unhygienic. In particular, the defect of steaming rice is that when the rice is poured into the rice steamer, the steam enters from the bottom of the rice steamer. The rice at the bottom is heated first. When the rice on the top of the barrel is heated, the rice at the bottom is already cooked. The water absorption is too large. When the rice is poured out, the rice at the bottom is all lumped together, which is very different from the rice on the top. After the wind cools it, whether it is manually stirred by hand or with a mixer, the rice cannot be dispersed grain by grain. The temperature of the lumped rice is very different from that of the dispersed rice. The red yeast strain cannot be evenly adhered to each grain of rice when poured and stirred, which is disadvantageous to the reproduction of mycelium, flower cultivation and later cultivation, and the quality cannot be guaranteed.

[0024] Example 1
[0025] A multifunctional wine yeast inoculation machine, such as Figure 1-2 As shown, it includes a body 2 with a cavity 1 inside, and the whole body is made of 304 stainless steel. A perforated bottom plate 3 is provided in the cavity 1. The aperture size of the perforated bottom plate 3 is suitable to prevent rice grains from leaking out. The edge of the perforated bottom plate 3 abuts against the inner wall of the cavity 1 and leaves a gap 4 with the bottom of the cavity 1. A stirring paddle rotating in the horizontal direction is provided above the perforated bottom plate 3. A steam inlet 6, an air inlet 7 and a drain 8 communicating with the interior of the cavity 1 are provided at the bottom of the cavity 1. The steam inlet 6 is connected to a steam generating device through a steam pipe, and the drain 8 is connected to a waste liquid bucket through a drain pipe. The air inlet 7 is connected to a blower through an air pipe. The air inlet 7 is connected to an air inlet pipe 11 in the direction where the air inlet 7 is located inside the cavity 1. The opening of the air inlet pipe 11 is horizontally oriented (making the opening of the air inlet pipe horizontally oriented is a liquid blocking structure to prevent water droplets condensed and dripping during the "cooling" process from entering the air inlet), and the steam inlet 6, the air inlet 7 and the drain 8 are all provided with corresponding valves for opening and closing. In addition, the bottom of the cavity 1 is arc-shaped, and the drain port 8 is located at the lowest point of the arc. The top of the cavity 1 is provided with an opening 9, and a detachable end cap 10 capable of sealing the opening is provided at the opening. Specifically, the end cap 10 is connected to the opening through an end cap buckle. The specific structure of the end cap buckle can seal the end cap and the opening and detachably connect them. It is a conventional structure in the art and will not be described in detail here.
[0026] The rotation of the stirring paddle is driven by a driving motor 12 (continuously variable speed motor) disposed below the cavity 1. The output shaft 13 of the driving motor 12 is fixedly connected to a stirring shaft 14. The stirring shaft 14 passes through the bottom of the cavity 1 and is vertically disposed inside the cavity 1. A sealing ring 22 is disposed at the intersection of the stirring shaft 14 and the bottom of the cavity 1 to ensure the sealing inside the cavity 1. The stirring paddle is horizontally fixedly disposed in the middle of the stirring shaft 14. A positioning bracket ring 15 is disposed at the top of the stirring shaft 14. The positioning bracket ring is equivalent to an annular structure that is fixedly connected to the inner wall of the cavity through a connecting rod and suspended directly above the stirring shaft. A bearing is disposed inside the positioning bracket ring, and the bearing fixing sleeve is disposed on the upper part of the stirring shaft. The stirring paddle includes a first stirring paddle 501 and a second stirring paddle 502. The first stirring paddle 501 is disposed above the second stirring paddle 502, and the two are disposed perpendicularly to each other in the axial direction ( Figure 1 The first stirring paddle and the second stirring paddle drawn in the figure are arranged in parallel, only for indicating the setting position of the two. In actual situation, the two are arranged vertically). Specifically, through holes 16 are arranged at intervals on the stirring paddle. The shape of the through holes 16 is not specifically limited, and the rice grains can pass through it. The semicircular through holes are adopted in this embodiment. When the stirring shaft 14 drives the stirring paddle to rotate, in order to reduce the resistance of the rice grains to the stirring paddle, the through holes 16 are arranged. In this way, when the stirring paddle rotates, a part of the rice grains "leak out" from the through holes. In addition, two stirring paddles perpendicular to each other in the axial direction are arranged, so that the stirring can be more stable and uniform, and the rice can be quickly dispersed.
[0027] In addition, an electronic exhaust valve 17 and a safety valve 18 are provided on the end cover 10, an electronic thermometer 20 for monitoring the temperature of the cavity 1 is provided on the body 2, an electronic pressure gauge 21 for monitoring the pressure of the cavity 1 is provided on the end cover 10, and an openable and closable discharge port 19 is provided on the side wall of the cavity. The lowest point of the discharge port 19 is flush with the upper edge of the punched bottom plate 3. After the entire inoculation operation is completed, the rice grains are discharged from the cavity 1.
[0028] Example 2
[0029] The basic structure is the same as that of the first embodiment, except that the first stirring paddle 501 and the second stirring paddle 502 on the stirring shaft 14 form a certain angle with the horizontal direction, which is 30° in this embodiment. In addition, the top of the stirring paddle is a wavy line structure, which can prevent the rice grains from sticking together when it is moved. Figure 2 shown.
[0030] Working and use process:
[0031] Add rice into the cavity 1 through the opening, add water to soak for a period of time, open the drain port 8 to drain the water and drain, seal the opening 9 with the end cover 10, then open the steam inlet 6 to allow steam to enter the cavity 1, turn on the drive motor 12 to drive the stirring paddle to rotate, so that the rice grains are heated and stirred, and the rice grains are evenly heated and absorb water. When the electronic temperature meter reaches 105 to 110 degrees or the electronic pressure meter reaches a pressure of about 0.05 MPa, the steam inlet 6 can be automatically closed (through the electronic steam inlet valve), and the values for different rice are different. Open the air inlet 7 and the blower, and let air into the cavity 1 (keep the exhaust valve 17 open during the air introduction process). When the temperature in the pot drops to 28 degrees in summer and 40 degrees in winter, close the blower and the air inlet 7, open the end cover 10, add the bacteria and continue to stir, so that the surface of each grain of rice is adhered to the bacteria, open the discharge port 19, release the material and send it to the ground culture room, bamboo dustpan, ventilation koji pool, and subsequent culture. After use, the quality of koji is greatly improved. In addition, a control module is included, the input ends of the electronic pressure gauge and the electronic temperature gauge are electrically connected to the control module, an electronic steam inlet valve is provided at the steam inlet, and the output end of the control module is electrically connected to the electronic steam inlet valve. When the temperature or pressure reaches a preset value, the control module sends a signal to close the electronic steam inlet valve.
