Abstract
Description
Technical Field
[0001] This utility model belongs to the field of liquor purification technology, and in particular relates to a liquor purification device. Background Technology
[0002] As a traditional Chinese distilled spirit, the quality and safety of baijiu depend on the harmony of flavor substances and the content of harmful impurities. Methanol is one of the key indicators affecting the safety of drinking baijiu. Methanol (boiling point 64.7℃) is mostly produced by the fermentation of pectin in the raw materials. Its toxicity is much higher than that of ethanol (boiling point 78℃). Excessive intake can lead to vision damage, nervous system poisoning, and even endanger life.
[0003] To reduce the content of harmful impurities such as methanol, various baijiu purification technologies have been developed in the industry. Among them, distillation is the core process for separating impurities in baijiu production, based on the difference in boiling points of different substances. However, methanol and ethanol have similar boiling points. In conventional distillation, methanol easily condenses along with ethanol vapor, resulting in limited separation efficiency. While extending the distillation time or increasing the distillation precision can improve the methanol removal rate, it significantly increases equipment complexity, energy consumption, and production costs. Moreover, some flavor substances (such as esters and alcohol aroma components) are lost during distillation, affecting the characteristics of baijiu. At the same time, after methanol evaporates, it easily forms a localized saturated vapor layer above the liquid surface, making it difficult to quickly detach from the liquor. Some gaseous methanol will redissolve back into the liquor, resulting in low removal efficiency. Utility Model Content
[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a liquor purification device, which at least partially solves the above technical problems.
[0005] The technical solution adopted by this utility model is as follows: A liquor purification device includes a purification box, in which a first metal filter A, a second metal filter B and an electrolytic cell are placed sequentially from top to bottom. The output end of the first metal filter A is connected to the input end of the second metal filter B, and the output end of the second metal filter B is connected to the input end of the electrolytic cell. The liquor to be purified passes through the first metal filter A, the second metal filter B and the electrolytic cell in sequence.
[0006] The first metal filter body A is a stainless steel powder sintered filter body, and an automatic temperature-controlled heating wire is installed inside the stainless steel powder sintered filter body. This heating wire can heat the liquor to 66-70 degrees Celsius.
[0007] The second metal filter body B is a stainless steel powder sintered filter body, and an automatic temperature-controlled heating wire is installed inside the stainless steel powder sintered filter body. This heating wire can heat the liquor to 70-75 degrees Celsius.
[0008] The beneficial effects of this utility model after adopting the above structure are as follows:
[0009] 1. During the upward movement of H2 and O2 generated after electrolysis, the impurities that have been heated and turned into gaseous state can be driven to flow smoothly out of the surface of the liquor and be released into the air.
[0010] 2. A small amount of H2 remaining in baijiu (Chinese liquor) can have a protective effect on the liver and gallbladder.
[0011] 3. The overall heating temperature of baijiu should not exceed 75 degrees Celsius, while the boiling point of ethanol is 78.3 degrees Celsius. The ethanol component in baijiu will not evaporate in large quantities and will not destroy the ester aroma components.
[0012] 4. Compared to the traditional method of warming alcohol before drinking, the boiling point temperature of different components is more precise;
[0013] 5. The first metal filter A and the second metal filter B in the heated state can prevent impurities (such as methanol) that have been vaporized from being dissolved back into the liquor due to temperature changes before floating out of the liquor, thus preventing them from being discharged smoothly.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0018] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0019] like Figure 1 As shown, a liquor purification device includes a purification chamber 1. Inside the purification chamber 1, from top to bottom, are placed a first metal filter A2, a second metal filter B3, and an electrolytic cell 4. The output end of the first metal filter A2 is connected to the input end of the second metal filter B3, and the output end of the second metal filter B3 is connected to the input end of the electrolytic cell 4. The liquor to be purified passes sequentially through the first metal filter A2, the second metal filter B3, and the electrolytic cell 4.
[0020] The first metal filter body A2 is a stainless steel powder sintered filter body, and an automatic temperature-controlled heating wire is installed inside the stainless steel powder sintered filter body. This heating wire can heat the liquor to 66-70 degrees Celsius.
[0021] The second metal filter body B3 is a stainless steel powder sintered filter body. The stainless steel powder sintered filter body is equipped with an automatic temperature-controlled heating wire, which can heat the liquor to 70-75 degrees Celsius.
[0022] When baijiu is electrolyzed in electrolysis cell 4, a large amount of H2 is generated. In a short period of time (the baijiu flows through this device and the electrolysis time is within 10 seconds), the amount of H2 generated by electrolyzing baijiu is 4 times the amount of H2 produced by electrolyzing water. The remaining electrolysis products will be heated and float to the surface along with gaseous hydrogen, leaving the liquid baijiu.
[0023] The specific process flow is as follows: ① The liquor flows downward through the first metal filter A2, where it is heated from room temperature to 66-70 degrees Celsius; ② The liquor continues to flow downward through the second metal filter B3, where it is heated to 70-75 degrees Celsius; ③ The heated liquor flows into the electrolysis tank 4, where a very small portion of the liquor is electrolyzed to generate H2 and O2 gases; ④ The H2 and O2 bubbles move upward, pass through the first metal filter A2 and the second metal filter B3, and are discharged into the atmosphere.
[0024] After heating, the baijiu (main component: ethanol) will have some impurities (such as methanol) reach their boiling point and turn into gaseous state due to the increased temperature. Accompanied by the rising H2 and O2 bubbles generated by electrolysis cell 4, the bubbles merge together and flow smoothly out of the baijiu liquid and into the air. During this process, the hydrogen and oxygen flowing through the first metal filter A2 and the second metal filter B3 are heated. The heated hydrogen and oxygen mix with the impurity gases (such as methanol) and move, and can be discharged while maintaining their boiling point temperature and vaporized state, ensuring that the impurities do not dissolve again in the baijiu liquid.
[0025] Impurities that can be removed from liquor (the boiling point of the impurity in parentheses) include: methanol (64.7 degrees Celsius), acetaldehyde (21 degrees Celsius), and low-boiling-point aldehydes (formaldehyde -19.5 degrees Celsius), etc.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
