Description

Technical Field

[0001] The invention relates to the technical field of red yeast rice wine production, in particular to a fermentation cooling device and a production process of red yeast rice wine. Background Art

[0002] Red yeast rice wine fermentation is a complex microbial metabolic process. Traditional red yeast rice wine fermentation mainly depends on the natural environment temperature. However, the fermentation process will generate heat, especially in the main fermentation stage. If the heat cannot be dissipated in time, the fermentation temperature will be too high. For example, the most suitable temperature for red yeast rice wine fermentation is generally around 25-30℃. When the temperature exceeds 35℃, the activity of microorganisms such as yeast will be inhibited or even die, thus affecting the normal fermentation and causing the quality of the wine to decline, such as the generation of odor, insufficient alcohol content and other problems.

[0003] According to the Chinese patent publication number CN111187690A, the patent provides an ancient brewing process including the following steps: (i) raw materials: weigh a certain amount of liquor, fresh glutinous rice and red yeast for use, (ii) crushing of raw materials: put the fresh glutinous rice after cleaning into the inside of a stirring device for full stirring, (iii) soaking of raw materials: soak a certain amount of glutinous rice after stirring, and then wash it, (iv) steaming of raw materials: after covering the steamer for steaming glutinous rice with a cloth, place the soaked glutinous rice on the cloth for steaming, (v) cooling of raw materials: place a plastic film in an open area, and then place the steamed glutinous rice on the film (vi) Mixing and fermenting of raw materials: add red yeast rice on top of the glutinous rice after stirring, and use machinery and manual labor to stir. (vii) Filling the cylinder: sprinkle a certain amount of red yeast rice on the bottom of the clean cylinder, and then pour in the mixed glutinous rice and red yeast rice, and then pour white wine into the cylinder. Seal the top of the wine cylinder with mulberry leaf paper and seal the mulberry leaf paper with a rope. (viii) Stirring and cleaning: after fermenting inside the cylinder for a period of time, open the cylinder mouth in the morning, noon and evening, stir the inside of the cylinder, clean the cylinder wall, and then seal it again. (ix) Unsealing: open the sealing paper on the cylinder and filter the lees through the filter net outside.

[0004] The traditional fermentation cooling technology is to set a jacket on the outer wall of the fermentation container, and pass cooling water into the jacket to take away the heat generated by the fermentation. However, the heat exchange between the jacket and the fermentation liquid is mainly concentrated near the container wall. The cooling effect on the fermentation liquid in the central area of ​​the fermentation container is not good, and there is a problem of uneven cooling. On the other hand, glutinous rice and red yeast rice will float repeatedly during the fermentation process, and they need to be manually pressed down and stirred every day, which makes the raw materials repeatedly exposed to the air, reducing the fermentation quality and increasing labor and supervision difficulties. Therefore, a fermentation cooling device and production process of red yeast rice are proposed to solve the above-mentioned problems. Summary of the invention

[0017] A manufacturing process of a red yeast rice wine fermentation cooling device comprises the following steps:

[0024] (III) Beneficial effects

[0025] Compared with the prior art, the present invention provides a fermentation cooling device and a production process for red yeast rice wine, which has the following beneficial effects:

[0026] 1. The fermentation cooling device and production process of red yeast rice wine adopts a cooling part to drive the rotating shaft to rotate through a motor, and the rotating tube rotates synchronously through gear meshing, and the stirring tube rotates accordingly to stir the raw materials. Cooling water enters the rotating tube from the water receiving pipe and fills the stirring tube. During the fermentation period, heat exchange cooling is carried out from the inside of the raw materials. At the same time, the cooling water will overflow from the overflow hole to fill the space under the partition plate, so that the bottom of the raw materials can also be cooled and transferred, and uniform heat exchange cooling is achieved from the inside to the outside, which effectively solves the problem of poor cooling effect in the central area of ​​the traditional fermentation container, ensures that the fermentation temperature is more uniform and stable, is conducive to microbial fermentation, and improves the quality of the wine.

[0027] 2. The fermentation cooling device and production process of the red yeast rice wine adopts an electromagnetic valve on the casing of the drainage part, which can automatically adjust the drainage volume. By controlling the discharge of cooling water to cooperate with the temperature sensor outside the fermentation tank, the heat exchange efficiency is changed to ensure that the fermentation temperature is within a suitable range, so that the fermentation process is not affected by excessively high or low temperature, and the wine quality is further improved.

[0028] 3. The fermentation cooling device and production process of the red yeast rice wine adopts a material storage box of the quantitative part, which is connected to the inner wall of the discharge port by rotating the rotating rod 2 and the surrounding blades to realize automatic quantitative feeding. A certain amount of red yeast rice and glutinous rice is stored between every two blades. The rotating rod 2 can put a fixed number of raw materials into the feed cover 2 every time it rotates one circle. The raw materials are added accurately according to the processing ratio. Compared with traditional manual feeding, it is more accurate and efficient, and can ensure the consistency of the amount added each time, which is conducive to the stable control of the fermentation process.

[0029] 4. The fermentation cooling device and production process of the red yeast rice wine adopts a water supply part that utilizes the reciprocating motion of the piston head in the tube, and drives the push-pull rod through the threaded cooperation of the slider and the reciprocating screw rod, so that the piston head reciprocates in the tube to absorb and spit water. When the piston head approaches the lifting pipe and passes through the through hole, water enters the lifting pipe and is sprayed toward the pressing roller from the water spray hole to wash away the remaining rice grains and allow the water to enter the fermentation tank. Water is automatically added in a quantitative manner according to the processing ratio to ensure the accurate ratio of water to raw materials. At the same time, the flushing function prevents the raw materials from sticking, thereby improving the mixing effect.

[0030] 5. The fermentation cooling device and production process of the red yeast rice wine adopts the second motor of the crushing part to drive the rotating rod one to rotate, so that the pressure roller rotates in the feed cover one, and the pressure teeth are staggered to fully crush the red yeast rice and glutinous rice. The inclined structure of the feed cover one and the feed cover two is conducive to the rolling of the raw materials, improves the mixing efficiency, replaces manual crushing to reduce labor, and makes the raw materials mixed more evenly, providing good conditions for fermentation.

[0031] 6. The fermentation cooling device and production process of the red yeast rice wine adopts a filter press part to intermittently start the telescopic movement of the electric push rod, and utilizes the filter membrane to automatically press down the floating red yeast rice and glutinous rice every day to achieve solid-liquid separation of the wine filtration. When the electric push rod is working, the motor is intermittently stopped, and after the electric push rod stops, the motor is intermittently started again to stir the stirring tube, ensuring that the raw materials can be stirred after each pressing, thereby promoting fermentation and foam generation, improving the mixing degree of the raw materials, accelerating the fermentation process, and avoiding the adverse effects of frequent manual operations on fermentation.

[0032] 7. The fermentation cooling device and production process of the red yeast rice wine adopt automatic filtering and stirring operations, which reduces the repeated exposure of raw materials to the air due to manual pressing and stirring, reduces the risk of contamination by foreign bacteria, improves the fermentation quality, and reduces labor and supervision difficulties.

[0033] 8. The fermentation cooling device and production process of the red yeast rice wine adopts the method of sealing the feed port during fermentation to make the fermentation tank in a sealed state for fermentation, and using a temperature sensor on the outer wall of the fermentation tank to monitor the fermentation temperature change, thereby reducing heat loss and mastering the fermentation temperature in real time, facilitating timely adjustment of cooling and other operations, ensuring that the fermentation is carried out at an appropriate temperature, and improving the fermentation stability and wine quality.

[0034] 9. The fermentation cooling device and production process of the red yeast rice wine adopts the method of disassembling the cooling part and the filter pressing part simultaneously with the cylinder cover. The modular design of each component is convenient for cleaning and maintenance of the inside of the device after the fermentation is completed, which is beneficial to keeping the device hygienic, extending the service life, reducing maintenance costs, ensuring the performance of the device when it is used next time, and providing guarantee for long-term stable production.

[0035] 10. The fermentation and cooling device and production process of the red yeast rice wine adopts the coordinated work of various components. For example, the coordinated part prompts the crushing part, the quantitative part and the water supply part to load materials synchronously in an appropriate proportion. The whole device automatically completes the fermentation process without excessive human intervention, which greatly improves work efficiency, reduces manual operation time and labor intensity, provides convenient conditions for batch and continuous wine production, increases production scale and output, accurately controls the proportion of raw materials, has good cooling and stirring effects, reduces pollution risks, etc., and ultimately improves the quality of the red yeast rice wine, making the taste, color, aroma and other aspects of the wine better, meeting consumers' demand for high-quality red yeast rice wine and enhancing product market competitiveness.

[0057] A manufacturing process of a red yeast rice wine fermentation cooling device comprises the following steps:

[0058] Step 1: Material preparation, using red yeast rice, glutinous rice and water in a ratio of 1:5:10, and sequentially putting the red yeast rice and glutinous rice in this ratio into the storage box 83 from the feeding port 84, and putting the water into the water tank 92;

[0059] Step 2: Mixing processing, the motor 2 73 works, the two pulleys 101 are driven by the transmission belt 102, and the blade 87 is prompted to turn a certain amount of red yeast rice and glutinous rice into the feed cover 2 72 in turn, and the red yeast rice and glutinous rice are fully crushed by the pressure roller 75 and the pressure teeth 76, and the red yeast rice and glutinous rice are entered into the fermentation tank 1, the pulley 2 103 and the pulley 3 104 are driven by the transmission belt 2 105, and the push-pull rod 96 is driven to reciprocate by the slider 95, so that the piston head 97 is used to repeatedly suck water and make the water rise through the lifting pipe 99, and spray it to the pressure roller 75 from the water spray hole 910, so as to wash away the rice grains adhering to the pressure roller 75, and make the water enter the fermentation tank 1;

[0060] Step 3: Uniform cooling: The motor 1 32 works to make the stirring tube 38 uniformly stir the red yeast rice, glutinous rice and water, and the cooling water is connected through the water receiving pipe 34, so that the cooling water flows along the rotating pipe 36 and fills each stirring tube 38. During the fermentation period, heat exchange cooling is performed from the inside of the raw materials. At the same time, the cooling water overflows from the overflow hole 43 and fills the space under the partition plate 6, so that the bottom of the raw materials can also be cooled and transferred. The heat exchange efficiency of the cooling water is controlled by the solenoid valve 42;

[0061] Step 4: Automatic filtration. During the fermentation period, the electric push rod 51 is intermittently activated to extend and retract, so that the filter membrane 55 automatically presses down the floating red yeast rice and glutinous rice every day, and filters the wine to the top to form solid-liquid separation, and the motor 32 is used to work intermittently, and the stirring operation is performed every day to promote the fermentation efficiency;

[0062] Step 5: Sealing and heat preservation: During the fermentation period, the feed port 84 is sealed so that the fermentation tank 1 is in a sealed state for fermentation, and a temperature sensor is used to monitor the fermentation temperature change on the outer wall of the fermentation tank 1;

[0063] Step 6: Extraction and maintenance. After fermentation is completed, the wine can be extracted using the faucet. The interior of the fermentation tank 1 can be cleaned and maintained by opening the tank cover 2. The cooling part 3 and the filter press part 5 are disassembled synchronously with the tank cover 2. Each component is modularized and easy to disassemble for cleaning and maintenance.

[0064] Working principle: put red yeast rice and glutinous rice in appropriate proportion into storage box 83 through feeding port 84, put water in appropriate proportion into water tank 92, start motor 2 73, make rotating rod 1 74 drive pressing roller 75 to rotate, make rotating rod 2 86 rotate synchronously through transmission belt 102, at this time, blade 87 cyclically turns over to put red yeast rice and glutinous rice into feeding cover 2 72, red yeast rice and glutinous rice roll into feeding cover 1 71, and are crushed by pressing roller 75 and pressing teeth 76, so as to fall into fermentation cylinder 1, and reciprocating screw rod 94 rotates synchronously through transmission belt 2 105, At this time, the slider 95 reciprocates and drives the piston head 97 on the push-pull rod 96 to reciprocate. Water is sucked into the tube 98 from the through hole and pushed into the lifting pipe 99 through the piston head 97, so that water is sprayed from the water spray hole 910 to the pressing roller 75, and then the residual rice grains on the pressing roller 75 are washed, and the red yeast rice and glutinous rice are washed at the same time to avoid adhesion to the pressing roller 75, the pressing teeth 76 and the inner wall of the feed cover 71. Under the synchronous movement of the cooperative part 10, the red yeast rice, glutinous rice and water are simultaneously added to the appropriate proportion for mixing, which is more convenient and efficient than manual proofreading under the traditional process.

[0065] The motor 32 drives the rotating shaft 33 to rotate, prompting the gear 37 to drive the rotating tube 36 to rotate synchronously, so that the stirring tube 38 rotates synchronously and stirs the red yeast rice, glutinous rice and water to further mix them fully. The motor 32 sets a fixed number of rotations according to the encoder to ensure that the four stirring tubes 38 are always aligned with the four tube sleeves 53 at each start and stop. The starting frequency of the electric push rod 51 is set intermittently. When the motor 32 is stopped, the electric push rod 51 telescopically moves, prompting the filter membrane 55 to descend and press down the floating red yeast rice and glutinous rice. The tube sleeve 53 is aligned and inserted into the stirring tube 38 without any obstruction, thereby filtering the wine upward. After the filter membrane 55 rises and resets, the motor 32 is turned on through the intermittent setting, and the stirring tube 38 is stirred to ensure that the red yeast rice and glutinous rice can be stirred each time they are pressed down, thereby promoting fermentation and foam generation, and further improving the mixing degree between the raw materials.

[0066] Cooling water is injected through the water receiving pipe 34, and the cooling water enters the rotating pipe 36 and fills each stirring tube 38. Under the action of the rotating joint 35, the rotating pipe 36 can continue to rotate when the cooling water flows. Therefore, during stirring, the raw materials are heat exchanged outwardly, and the uniformity of heat exchange and cooling is improved. The cooling water overflows from the overflow hole 43 into the space between the partition plate 6 and the bottom of the fermentation tank 1 to fill it, thereby performing heat exchange and cooling below the raw materials, further improving the cooling efficiency and uniformity.

[0067] The cooling water discharge efficiency is adjusted by opening and closing the electromagnetic valve 42, and the heat exchange efficiency is changed in conjunction with the temperature sensor external to the fermentation tank 1 to ensure that the fermentation temperature is within a suitable range. After the electromagnetic valve 42 is opened, the cooling water flows back into the sleeve 41 through the overflow hole 43, and is discharged through the lower end of the sleeve 41. The cooling part 3 and the filter press part 5 work intermittently, and the crushing part 7, the quantitative part 8 and the water supply part 9 cooperate to load the materials in a suitable proportion to automatically realize the fermentation of red yeast rice wine. The fermentation is automatically completed without excessive human intervention, which greatly improves the work efficiency, reduces the difficulty of winemaking, and provides convenience for batch and continuous winemaking production.
