Problems solved by technology

Many liquor companies began to label the vintage at will, and some wineries that have only been in operation for a few years openly sold vintage wine for decades, which made the vintage wine market more and more chaotic and seriously damaged the interests of consumers

specific Embodiment 1

[0064] Such as figure 1 As shown, a vacuum freezing transfer device includes a first vacuum valve 1, a second vacuum valve 2, a first thermos cup 3, a second thermos cup 4, a first straight-through metal joint 5, a three-way metal joint 6, a first A quartz tube 7, a second quartz tube 8, a vacuum gauge 11, a first cold trap 12 and a vacuum pump 13,

[0065] One end of the first straight-through metal joint 5 communicates with the open end of the second quartz tube 8, and the end of the second quartz tube 8 is inserted into the second thermos cup 4. The three-way metal joint 6 includes an A joint, a B joint and a C joint. joint, the other end of the first straight metal joint 5 communicates with the A joint of the three-way metal joint 6 through a pipeline, and the connecting pipeline between the first straight-through metal joint 5 and the three-way metal joint 6 is equipped with a second vacuum valve 2, The second vacuum valve 2 is used to control the closing of the pipeline...

specific Embodiment 2

[0113] Roughly the same as specific embodiment 1, the difference only lies in:

[0114] CO in step (2) 2 The gas reacts with zinc powder as a reducing agent at 400°C for 8 hours, and at the same time reacts with iron powder as a catalyst at 600°C for 8 hours to convert CO 2 gas conversion to graphite

specific Embodiment 3

[0115] Roughly the same as specific embodiment 1, the difference only lies in:

[0116] CO in step (2) 2 The gas reacts with zinc powder as a reducing agent at 400°C for 7 hours, and at the same time reacts with iron powder as a catalyst at 600°C for 7 hours to convert CO 2 gas conversion to graphite

Abstract

The invention relates to a method for identifying vintage liquor and a vacuum freezing transfer device. A vacuum freezing transfer device includes a first vacuum valve, a second vacuum valve, a first thermos cup, a second thermos cup, and a first straight-through metal joint. , three-way metal joint, first quartz tube, second quartz tube, vacuum gauge, first cold trap and vacuum pump. A method for identifying vintage liquor, comprising the following steps: 1. extracting ethanol from liquor to be detected; 2. reacting ethanol in a muffle furnace for 3 hours; 3. converting CO2 gas into graphite; 4. putting graphite into an accelerator Measure the 14C concentration F value of the liquor to be detected; 5 establish the correlation change curve between the cellar age of the liquor and the 14C concentration F value, and fit the data to obtain the correlation formula; 6 Calculate the 14C concentration F value of the liquor to be detected The value is substituted into the formula to obtain the year of the liquor to be tested. The invention has the advantages of less test sample amount, short test time, high precision and the like.

Description

technical field [0001] The invention belongs to the technical field of wine identification, and in particular relates to an identification method of vintage liquor and a vacuum freezing transfer device. Background technique [0002] What exactly is vintage wine? The aging of vintage wine should be called "cellar storage" in terms of technology, that is, the wine distilled by traditional techniques is stored in containers. Under certain conditions, after a period of storage, the wine will lose its dryness and spicy The taste is obviously reduced, the taste of the wine is soft, the aroma is increased, and the body of the wine becomes harmonious. [0003] As a high-end product of Chinese liquor companies, "vintage wine" is facing a crisis of trust from many consumers because of the indistinguishable authenticity of the label "year", which makes the rapid development of the "vintage wine" market face a huge bottleneck. [0004] As the saying goes, wine is the fragrance of old, ...
