Description

Technical Field

[0001] This utility model relates to the field of sake production technology, specifically to an improved rice sake pressure filtration device. Background Technology

[0002] Sake is made from finely polished white rice using a unique brewing process. It typically has an alcohol content of 15% vol or higher, and is pale yellow or colorless, clear and transparent, with a distinctive aroma and flavor. The brewing technique involves rice polishing, koji making, and three stages of shiko (a process of refining the rice into sake). It requires the use of high-quality rice and water, with the rice polishing ratio directly affecting the quality grade of the sake.

[0003] The production of sake requires a filter press. Currently, the filter presses used in sake production are mainly mechanical, which cannot forcibly squeeze out the bound water and capillary water inside the sake raw materials. This results in a relatively high water content in the filtered sake raw materials, reducing the efficiency of the filter press. To solve these technical problems, we have designed an improved rice sake filter press. Utility Model Content

[0004] The purpose of this invention is to provide an improved rice sake filtration device that has the advantage of using high-pressure gas to filter sake. It solves the problem that when using mechanical filtration to produce sake, the bound water and capillary water inside the sake raw material cannot be forcibly squeezed out, resulting in a high water content in the sake raw material after filtration, which reduces the filtration efficiency.

Baffle plates are connected to the left and right sides of the top of the semi-circular cover, and several drainage holes are opened at the bottom of the inner wall of the semi-circular cover.

[0006] Preferably, a solenoid valve is installed on the exhaust pipe, and a pressure relief pipe is installed outside the exhaust pipe and below the solenoid valve, with a pressure relief valve installed on the pressure relief pipe.

Detailed Implementation

[0022] Please see Figures 1-7 An improved rice sake pressure filtration device includes a housing 3 and a cone 10. A drain pipe 1 is connected to the bottom of the front side of the housing 3, and a control box 4 is installed on the top of the front side of the housing 3. A pressure filtration component 2 is installed inside and on the front side of the housing 3. A support ring 16 is connected to the top of the inner wall of the housing 3, and a cover plate 5 is bolted to the top of the support ring 16. A pressure gauge 12, an air injection pipe 6, an exhaust pipe 15, and a delivery pump 8 are sequentially installed on the top of the cover plate 5 from front to back. The liquid extraction end of the delivery pump 8 is connected to the cone 10. The rear of the housing 3... A sealing component 11 is installed on the side. The sealing component 11 includes an electric telescopic rod 115. The telescopic end of the electric telescopic rod 115 is connected to a moving column 114. The bottom front side of the moving column 114 is connected to a connecting column 116. The front side of the connecting column 116 is connected to a sealing disc 113. The front side of the sealing disc 113 is connected to a sealing plug 112. The filter press component 2 includes a drive motor 21 and a semi-circular cover 25. The left and right sides of the top of the semi-circular cover 25 are connected to baffles 23. Several drainage holes 26 are opened at the bottom of the inner wall of the semi-circular cover 25.

[0023] A solenoid valve 14 is installed on the exhaust pipe 15. A pressure relief pipe 13 is installed outside the exhaust pipe 15 and below the solenoid valve 14. A pressure relief valve 7 is installed on the pressure relief pipe 13. When the solenoid valve 14 is opened, the high-pressure gas in the chassis 3 can be discharged through the exhaust pipe 15. With the cooperation of the pressure relief pipe 13 and the pressure relief valve 7, when the pressure in the chassis 3 is too high, the pressure relief valve 7 will automatically open to discharge the excess gas.

[0024] The side of the gas injection pipe 6 away from the casing 3 is connected to the external nitrogen inlet pipe. The top of the cone 10 is connected to the external injection pipe 9 through a flange. The external injection pipe 9 is used to transport the sake raw materials. An electric valve is installed on the external nitrogen inlet pipe. An electric valve is also installed on the drain pipe 1.

[0025] The rear side of the chassis 3 is provided with a sealing window that works in conjunction with the sealing plug 112. The front side of the sealing plate 113 is in contact with the chassis 3, and the front side of the electric telescopic rod 115 is connected to the chassis 3. The sealing window can be sealed by the sealing plug 112.

[0026] A sealing slot is provided on the rear side of the chassis 3, outside the sealing window. A sealing ring 111 is connected to the front side of the sealing plate 113, outside the sealing plug 112, to cooperate with the sealing slot. The cooperation between the sealing slot and the sealing ring 111 improves the sealing performance between the sealing plate 113 and the chassis 3.

[0027] The rear side of the drive motor 21 is connected to the bottom of the front side of the housing 3. The front and rear sides of the shielding slope 23 and the semi-circular cover 25 are connected to the front and rear sides of the inner wall of the housing 3. The top of the two shielding slopes 23 on the opposite side are connected to the top of the left and right sides of the inner wall of the housing 3 respectively. The raw materials of sake can be stored through the semi-circular cover 25.

[0028] The output end of the drive motor 21 is connected to the drive shaft 24, the rear side of the drive shaft 24 extends into the interior of the semi-circular cover 25, and the outside of the drive shaft 24 is connected to the spiral push scissor 22; through the cooperation of the spiral push scissor 22, the filtered sake raw materials can be pushed.

[0029] In operation, the transfer pump 8 is turned on using the control box 4. The transfer pump 8 draws the sake raw materials from the cone 10 into the semi-circular cover 25. The transfer pump 8 automatically shuts off after running for the rated time. The electric valve on the external nitrogen inlet pipe is opened, and high-pressure nitrogen from the outside is injected into the machine housing 3. The pressure inside the machine housing 3 gradually increases, accelerating the separation of sake from the sake raw materials. The separated sake falls below the semi-circular cover 25. When the pressure inside the machine housing 3 reaches the set value, the electric valve on the external nitrogen inlet pipe is closed. After pressure filtration, first open the solenoid valve 14, then open the electric valve on the drain pipe 1. Sake is discharged from the drain pipe 1. After the amount of sake discharged from the drain pipe 1 is greatly reduced, turn on the drive motor 21 to make the drive shaft 24 rotate. The drive shaft 24 drives the screw to push the screw cutter 22 to rotate. The screw pushes the screw cutter 22 to push the filtered sake raw material backward. The telescopic end of the electric telescopic rod 115 extends and drives the moving column 114 and the connecting column 116 to move backward, so that the sealing plug 112 is disengaged from the sealing window, thereby discharging the remaining sake raw material. Then, reset each component in sequence and add sake raw material again. The benefits of using high pressure for sake filtration: High-pressure gas filtration, by applying higher pressure, can more thoroughly compress the filter cake, forcibly squeezing out bound water and capillary water hidden inside the particles, thus significantly reducing the moisture content of the filter cake. This efficient dehydration capacity means a larger single-batch processing capacity, meeting the needs of large-scale industrial production, while maintaining a relatively short cycle time. Furthermore, high-pressure filtration technology helps remove large molecular impurities, microorganisms, and insoluble substances from sake, making the liquor clearer and more transparent, improving its appearance quality. In addition, by selectively removing some aldehydes that cause spiciness, it can also make the sake taste smoother and more mellow. Moreover, sake treated with high-pressure filtration is less prone to sedimentation and spoilage during storage and transportation, ensuring product quality stability.

[0030] In summary, this improved rice sake pressure filtration device, through the coordinated use of the pressure filtration component 2, the air injection pipe 6, and the exhaust pipe 15, solves the problem that mechanical pressure filtration in sake production cannot forcibly squeeze out the bound water and capillary water inside the sake raw materials, resulting in a still high water content in the sake raw materials after pressure filtration, which reduces the pressure filtration efficiency.
