Description

TECHNICAL FIELD

[0001] The present application relates to a sterilization device, in particular to a sterilization device for yellow rice wine. BACKGROUND

[0002] Yellow rice wine is one of the three major brewed wines in the world, and is the oldest traditional wine unique to China. It is a gem of Chinese wine and is known as the "national wine". Yellow rice wine has a history of more than 5,000 years and rich cultural connotations. Its traditional brewing process has been passed down to the present day.

[0003] In recent years, thanks to sustained economic growth, the brewing industry has shown structural changes brought about by consumer upgrading. The demand for wine has shifted from "simple preference" to "nutrition and health care", and the concept of high and strong drinking has been increasingly abandoned. The advantages of low-alcohol, nutrition and health care of yellow rice wine have gradually emerged. Compared with other wines, yellow rice wine is more in line with the green, nutritional and healthy trend of modern society, and is a truly healthy concept wine. It has been listed by the state as one of the beverage wines to be supported and developed.

[0004] At present, domestic yellow rice wine enterprises basically use traditional high-temperature sterilization methods for yellow rice wine sterilization. The main method is direct steam heating, with a sterilization temperature of 80-85℃ and a sterilization time of 10-20min. Some sterilization times are even longer. During the heating process, the alcohol volatilization amount reaches 4-5 mass%, and the related flavor substances in yellow rice wine are also volatilized and lost at the same time, thereby affecting the aroma and flavor of yellow rice wine. Due to the uneven heating and long heating time, the nutrients such as protein in yellow rice wine are denatured due to long-term high-temperature action, affecting the nutritional nature of yellow rice wine, and coking phenomenon occurs in the heating cavity, which makes the heating cavity difficult to clean, thereby affecting the sterilization effect of yellow rice wine.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] In the basic embodiment of the present application, as Figure 1As shown, a yellow wine sterilization device is provided, which comprises a control module, a heating tank 1, a liquid return tank 2, a storage tank 3 and a pressurizing device 4. The heating tank 1 is provided with a heating tank liquid inlet bin 5 and a heating tank liquid outlet bin 6, so that the yellow wine in the heating tank liquid inlet bin 5 can be heated by the yellow wine in the heating tank liquid outlet bin 6 in the working state. The heating tank liquid inlet bin 5 and the heating tank liquid outlet bin 6 are provided with a liquid inlet pumping device at the communication position. The control module is electrically connected with the liquid inlet pumping device and the heating tank 1 respectively, so as to control the working of the liquid inlet pumping device and the heating temperature of the heating tank 1. The pressurizing device 4 is connected with the heating tank liquid outlet bin 6, so as to pressurize the heating tank liquid outlet bin 6. The liquid return tank 2 is connected with the heating tank 1, so as to input the yellow wine into the heating tank 1 and recycle the yellow wine heated by the heating tank 1, so that the recycled yellow wine heated by the heating tank 1 can preheat the yellow wine entering from the liquid return tank liquid inlet port 201 of the liquid return tank 2. The liquid return tank liquid outlet port 202 of the liquid return tank 2 and the storage tank liquid inlet port 301 of the storage tank 3 are connected, and the cooling device 7 is arranged between the liquid return tank liquid outlet port 202 and the storage tank liquid inlet port 301.

[0036] According to the present application, the communication position of the heating tank liquid inlet bin 5 and the heating tank liquid outlet bin 6 is always kept above the liquid level in the heating tank liquid inlet bin 5 and the heating tank liquid outlet bin 6, so as to ensure that the yellow wine in the heating tank liquid inlet bin 5 and the heating tank liquid outlet bin 6 will not affect each other in the case that the liquid inlet pumping device does not work. When the liquid inlet pumping device does not work, the heating tank liquid inlet bin 5 and the heating tank liquid outlet bin 6 are not in air communication. The heating tank liquid inlet bin 5 can also be arranged in the heating tank liquid outlet bin 6. Preferably, the heating tank liquid inlet bin 5 is arranged inside the heating tank liquid outlet bin 6, so that the heating tank liquid inlet bin 5 can be heated by the yellow wine in the heating tank liquid outlet bin 6, so that the yellow wine in the heating tank liquid inlet bin 5 and the yellow wine in the heating tank liquid outlet bin 6 can be at two heating temperatures. The pressurizing device 4 can be any device capable of pressurizing the heating tank liquid outlet bin 6. Specifically, it can be a separate air pump or a pressurizing pumping device connected with a gas tank. The air pump pumps air into the heating tank liquid inlet bin 5 or the pressurizing pumping device pumps gas into the heating tank liquid inlet bin 5 to make it in a high pressure state, so as to achieve the purpose of pressurization. Preferably, the pressurizing pumping device connected with the gas tank can improve the cleanliness of the pumped gas into the heating tank liquid inlet bin 5, so as to further ensure the safety and health of the yellow wine.

[0037] Specifically, the yellow rice wine entering the liquid return tank 2 from the liquid return tank inlet 201 and the yellow rice wine entering the liquid return tank 2 from the heating tank outlet 6 are not mixed in the liquid return tank 2, and the two can be in two containers in the liquid return tank 2 respectively, but the yellow rice wine entering the liquid return tank 2 from the heating tank outlet 6 can be preheated by the yellow rice wine entering from the liquid return tank inlet 201. The two containers can be any structure or connection structure that can achieve the above heating. The top of the heating tank outlet 6 is provided with a pressure relief valve 13, which can be connected with the control module to control the operation of the pressure relief valve 13 through the control module, or can not be connected with the control module, and the operation of the pressure relief valve 13 is manually controlled by the operator. Whether to start the pressure relief valve 13 can be determined according to the needs during the operation.

[0038] The outlet of the heating tank outlet 6 can be arranged at the bottom of the heating tank outlet 6, or at the top of the heating tank outlet 6. When arranged at the bottom, a control valve is arranged between the heating tank outlet 6 and the liquid return tank 2 to ensure that the heating tank outlet 6 is disconnected from the liquid return tank 2 during sterilization, and connected after sterilization is completed. The connection between the heating tank outlet 6 and the liquid return tank 2 is provided with an outlet pumping device to pump the yellow rice wine in the heating tank outlet 6 into the liquid return tank 2 or the storage tank 3. The heating tank 1 can accurately control the heating temperature during heating, that is, the heating tank 1 is provided with a heating system capable of accurately controlling the heating temperature.

[0039] The yellow rice wine sterilization device provided by the above basic embodiment works as follows. Yellow rice wine is injected into the liquid return tank inlet 201 to pass through the liquid return tank 2 into the heating tank inlet 6, the yellow rice wine in the heating tank inlet 6 is pumped into the heating tank outlet 6 by the inlet pumping device, then the connection between the heating tank inlet 6 and the heating tank outlet 6 is sealed, the pressurizing device 4 is started to make the heating tank outlet 6 at 0.5 MPa (at this time the boiling point of the yellow rice wine is about 98℃), the heating temperature of the heating tank 1 is set to 92℃, and the sterilization is completed after heating for 2-5 min. After or during sterilization, yellow rice wine is continuously injected into the heating tank inlet 6 through the liquid return tank inlet 201, at this time, the yellow rice wine in the heating tank outlet 6 and the yellow rice wine entering the liquid return tank 2 from the heating tank outlet 6 can preheat the yellow rice wine before entering the heating tank outlet 6. After sterilization is completed, the outlet pumping device is started to make the yellow rice wine enter the liquid return tank 2 from the heating tank outlet 6, and preheat the yellow rice wine in the liquid return tank 2, then the yellow rice wine is cooled by the cooling device 7 and then stored in the storage tank 3. Then the yellow rice wine in the heating tank inlet 6 is continuously pumped into the heating tank outlet 6, and the above operation is repeated until all the yellow rice wine is sterilized, so as to achieve the purpose of sterilization.

[0040] The sterilization device for yellow rice wine provided by the basic embodiment can make the liquid outlet bin 6 of the heating tank in a high pressure state through the setting of the pressurizing device, so as to increase the boiling point of the yellow rice wine in the liquid outlet bin 6 of the heating tank, thereby increasing the sterilization temperature of the yellow rice wine in the liquid outlet bin 6 of the heating tank. At high temperature, the sterilization time is reduced, and the sterilization efficiency is improved. Such a setting can reduce the time for sterilizing the yellow rice wine, improve the sterilization efficiency, and reduce the volatilization of flavoring substances in the yellow rice wine. The setting of the liquid return tank 2, the liquid inlet bin 5 of the heating tank, and the liquid outlet bin 6 of the heating tank can make the yellow rice wine in the liquid outlet bin 6 of the heating tank and the yellow rice wine going out of the liquid outlet bin 6 of the heating tank preheat the yellow rice wine entering the liquid return tank 2 from the liquid inlet port 201 and the yellow rice wine in the liquid inlet bin 5 of the heating tank. The heat of the yellow rice wine in the liquid outlet bin 6 of the heating tank and the yellow rice wine going out of the liquid outlet bin 6 of the heating tank can be fully utilized to reduce heat loss and improve energy utilization. At the same time, the heating time of the yellow rice wine in the liquid outlet bin 6 of the heating tank can be reduced, the sterilization time is further reduced, and the yellow rice wine is not carbonized due to the long sterilization time during the sterilization process, thereby further ensuring the flavor of the yellow rice wine.

[0041] In one specific embodiment of the present application, as shown in Figure 2 The liquid outlet bin 6 of the heating tank and the liquid inlet bin 5 of the heating tank are both set in a spiral shape, and the liquid outlet bin 6 of the heating tank is sleeved outside the liquid inlet bin 5 of the heating tank. The liquid outlet bin 6 of the heating tank is set in a spiral shape, which can increase the heating area during heating, thereby further reducing the heating time required, and can ensure the temperature of the yellow rice wine in the liquid outlet bin 6 of the heating tank during sterilization, thereby further improving the sterilization effect. The liquid inlet bin 5 of the heating tank is set in a spiral shape, and the liquid outlet bin 6 of the heating tank is sleeved outside the liquid inlet bin 5 of the heating tank, which can further increase the heating area between the liquid inlet bin 5 of the heating tank and the liquid outlet bin 6 of the heating tank, thereby improving the preheating effect of the yellow rice wine in the liquid outlet bin 6 of the heating tank on the yellow rice wine in the liquid inlet bin of the heating tank.

[0042] According to the present application, the outer threaded end of the liquid outlet bin 6 of the heating tank is provided with a liquid outlet port of the liquid outlet bin of the heating tank, and the inner threaded end is provided with a liquid inlet port of the liquid inlet bin of the heating tank. The outer threaded end of the liquid inlet bin 5 of the heating tank is provided with a liquid inlet port of the liquid inlet bin of the heating tank, and the inner threaded end is provided with a liquid outlet port of the liquid inlet bin of the heating tank.

[0043] In one specific embodiment of the present application, as shown in Figure 2As shown, the caliber of the outlet of the heating tank liquid outlet bin 6 gradually increases from the liquid inlet to the liquid outlet. That is, the inner diameter gradually increases from the cavity at the inlet of the heating tank liquid outlet bin 6 to the cavity at the outlet of the heating tank liquid outlet bin 6. This arrangement increases the proportion of yellow rice wine that can avoid contact with the heating tank liquid outlet bin 6 in the early stage of entering the heating tank liquid outlet bin 6, thereby effectively increasing the temperature of the yellow rice wine in the early stage of entering. At the same time, increasing the inner diameter at the rear end can increase the amount of stored yellow rice wine, thereby effectively increasing the volume of the heating tank liquid outlet bin 6 and increasing the amount of yellow rice wine in the sterilization process.

[0044] In one specific embodiment of the present application, the heating tank 1 is provided with a water bath tank 8 and a heater 9. The water bath tank 8 is provided with a water bath temperature sensor, and the heater 9 can heat the water in the water bath tank 8. The control module is connected with the water bath temperature sensor and the heater 9, so as to control the start and stop of the heater 9 by comparing the difference between the temperature detected by the water bath temperature sensor and the set temperature.

[0045] According to the present application, the heating tank liquid outlet bin 6 is arranged inside the water bath tank 8, and the yellow rice wine in the heating tank liquid outlet bin 6 can be heated by the water in the water bath tank 8.

[0046] The water bath heating method can effectively control the sterilization temperature in the heating tank liquid outlet bin 6, and can also make the yellow rice wine in the heating tank liquid outlet bin 6 evenly heated, thereby reducing the occurrence of local coking and further ensuring the taste of the yellow rice wine.

[0047] In one specific embodiment of the present application, the heating tank liquid outlet bin 6 is provided with a pressure sensor 14, and the control module is electrically connected with the pressure sensor 14 to control the operation of the pressurizing device 4 according to the pressure value detected by the pressure sensor 14. The pressure in the heating tank liquid outlet bin 6 can be accurately controlled, thereby determining the sterilization temperature and ensuring the smooth progress of sterilization without causing the volatilization of flavor substances in the yellow rice wine.

[0048] Specifically, the pressure sensor 14 is arranged above the liquid level of the yellow rice wine when the heating tank liquid outlet bin 6 is working. Preferably, the pressure sensor 14 is arranged at the top of the heating tank liquid outlet bin 6, so as to accurately detect the air pressure in the heating tank liquid outlet bin 6 without being affected by the liquid pressure.

[0049] In one specific embodiment of the present application, the inlet of the heating tank liquid inlet bin 5 and the heating tank liquid outlet bin 6 are each provided with an electromagnetic valve, and the control module is electrically connected with the electromagnetic valve to control the operation of the electromagnetic valve. The operation of the electromagnetic valve is more convenient, mechanized and labor-saving through the control of the control module.

That is, the top of the heating tank liquid inlet bin 5 and the top of the heating tank liquid outlet bin 6 are both made of a light-transmitting material, which can be a safe material that can transmit light, or an organic or inorganic material that has no negative effect on human beings, such as quartz or glass. Preferably, the light-transmitting material is glass, which can prevent the corrosion of alcohol on the organic material, further ensure the taste of the yellow rice wine, and also reduce the production cost.

[0051] The yellow rice wine sterilization device provided by the above specific embodiment can achieve the sterilization of the yellow rice wine when the ultraviolet lamp tube is turned on, and the ultraviolet light is emitted into the interior of the heating tank liquid inlet bin 5 and the heating tank liquid outlet bin 6 through the top of the heating tank liquid inlet bin 5 and the top of the heating tank liquid outlet bin 6. The reflecting surface can reflect the ultraviolet light emitted into the heating tank liquid inlet bin 5 and the heating tank liquid outlet bin 6 multiple times, so that the ultraviolet light can be fully utilized and the sterilization effect of the ultraviolet light can be improved. Moreover, the ultraviolet lamp tube, the light-transmitting top and the reflecting surface can simultaneously sterilize the yellow rice wine in the heating tank liquid inlet bin 5 and the heating tank liquid outlet bin 6, and the sterilization can be performed multiple times, so that the sterilization effect is better and the heating time can be further reduced.

[0052] The ultraviolet wave emitted by the ultraviolet lamp tube has a wavelength range of 250-275 nm and a power of 20-40 W.

[0053] In one specific embodiment of the present application, the heating tank liquid outlet bin 6 is provided with an ultrasonic probe 15, and the ultrasonic probe 15 is connected with an ultrasonic emitter to enable the ultrasonic treatment of the yellow rice wine. The control module is electrically connected with the ultrasonic emitter to control the operation of the ultrasonic emitter.

Moreover, the heating temperature in the present application is relatively high, so that the ultrasonic time during the ultrasonic sterilization can be reduced, and the coking of the yellow rice wine can be further prevented.

[0055] In order to further improve the heat exchange effect, in one specific embodiment of the present application, the liquid return tank 2 is provided with a liquid return tank liquid inlet pipe 10, the outlet end of the liquid return tank liquid inlet pipe 10 penetrates through the liquid return inlet 203 and communicates with the heating tank liquid inlet bin 5, the heating tank liquid outlet bin 6 is connected with the liquid return inlet 203 through the liquid outlet pipe 11, and one end of the liquid return tank liquid inlet pipe 10 is arranged in the liquid outlet pipe 11; the liquid return tank liquid inlet pipe 10 comprises a plurality of straight pipe portions and a plurality of bending portions, and two adjacent straight pipe portions are connected by the bending portion to form a U-shaped pipe.

[0056] Specifically, that is, the part of the liquid return tank liquid inlet pipe 10 extending out of the liquid return tank 2 is wrapped in the liquid outlet pipe 11, and the yellow rice wine sterilized in the heating tank liquid inlet bin 5 can heat the yellow rice wine in the liquid outlet pipe 11, so that the heat of the yellow rice wine can be more fully utilized, and the energy loss can be reduced.

[0059] In one specific embodiment of the present application, the cooling device 7 is a water-cooled cooling device, the water inlet of the water-cooled cooling device is arranged at the bottom of one end adjacent to the storage tank 3, and the water outlet of the water-cooled cooling device is arranged at the top of one end adjacent to the liquid return tank 2. By arranging the water inlet at the end adjacent to the storage tank 3, the cooling device can have better cooling effect, so that the temperature of the yellow rice wine passing through the cooling device can be reduced to the lowest.

[0063] When the yellow rice sterilization device provided by the above preferred embodiment is in operation, the ultraviolet lamp is turned on, and after sterilization for 10 minutes, the ultraviolet lamp is kept on, yellow rice is injected into the liquid inlet 201 of the liquid return tank, so that the yellow rice passes through the liquid return tank 2 and enters the heating tank liquid inlet compartment 5. The yellow rice in the heating tank liquid inlet compartment 5 is pumped to the heating tank liquid outlet compartment 6 by the liquid inlet pumping device. Then, the communication between the heating tank liquid inlet compartment 5 and the heating tank liquid outlet compartment 6 is sealed, and the outlet of the heating tank liquid outlet compartment 6 is sealed. The pressurizing device 4 is started to make the heating tank liquid outlet compartment 6 under the condition of 0.5 MPa. The heating temperature of the heating tank 1 is set to 92℃, and the ultrasonic frequency is set to 30 kHz, and the ultrasonic time is 20 s. In this case, the heating is performed for 2-5 minutes to complete the sterilization. After the sterilization is completed or during the sterilization, the yellow rice is continuously injected into the heating tank liquid inlet compartment 5 through the liquid inlet 201 of the liquid return tank. At this time, the yellow rice in the heating tank liquid outlet compartment 6 and the yellow rice entering the liquid return tank 2 from the heating tank liquid outlet compartment 6 preheat the yellow rice before entering the heating tank liquid outlet compartment 6.

[0064] The yellow rice wine sterilization device provided by the basic embodiment can make the heating tank liquid outlet bin 6 in a high pressure state through the setting of the pressurizing device, so as to increase the boiling point of the yellow rice wine in the heating tank liquid outlet bin 6, thereby increasing the sterilization temperature of the yellow rice wine in the heating tank liquid outlet bin 6. At high temperature, the sterilization time is reduced, and the sterilization efficiency is improved. Moreover, the setting of the pressure sensor 14 and the water bath temperature sensor can accurately control the pressure and heating temperature in the heating tank liquid outlet bin 6. Such a setting can not only reduce the time for sterilizing the yellow rice wine, but also improve the sterilization efficiency and reduce the volatilization of flavoring substances in the yellow rice wine, thereby ensuring the taste of the yellow rice wine. Through the setting of the liquid return tank liquid inlet pipe 10, the liquid return tank 2, the heating tank liquid inlet bin 5 and the heating tank liquid outlet bin 6, the yellow rice wine in the heating tank liquid outlet bin 6 and the yellow rice wine discharged from the heating tank liquid outlet bin 6 can preheat the yellow rice wine entering the liquid return tank 2 from the liquid return tank liquid inlet 201 and the yellow rice wine in the heating tank liquid inlet bin 5. The heat of the yellow rice wine in the heating tank liquid outlet bin 6 and the yellow rice wine discharged from the heating tank liquid outlet bin 6 can be fully utilized to reduce heat loss and improve energy utilization. At the same time, the heating time of the yellow rice wine in the heating tank liquid outlet bin 6 can be reduced, thereby further reducing the sterilization time and preventing coking during the sterilization process, and further ensuring the flavor of the yellow rice wine.
