Description

Technical Field

[0001] The utility model relates to wine making, and more particularly to a pH meter specially used for detecting the acidity of cellar mud and a quick detection device for ecological indicators of cellar mud. Background Art

[0002] Baijiu (Chinese liquor) is a distilled spirit unique to China and one of the world's six major distilled spirits (along with Brandy, Whisky, Vodka, Gin, Rum, and Spirit). It is made from a fermented mash made from starch or sugar, followed by distillation. Baijiu's flavor profiles are primarily categorized as Luzhou-flavor, Maotai-flavor, Qing-flavor, Rice-flavor, Sesame-flavor, and others.

[0003] Liquor production relies on cellar mud, which provides a suitable environment for fermentation by microorganisms. The complex energy metabolism of these microorganisms within the cellar provides a continuous source of energy for baijiu production. Cellar mud, acting as a "cellar nourishing lees," infuses the mash with volatile trace aroma components, absorbed through long fermentation, enhancing the fullness and harmony of the flavor. Cellar mud is composed of water, total acids, total esters, humus, ammoniacal nitrogen, and available phosphorus, and has a high solids content.

[0004] Due to the importance of cellar mud in liquor production, it is necessary to detect cellar mud. However, the existing detection methods for cellar mud have the following defects:

[0005] (1) In testing the acidity of cellar mud, due to its high solid content, there are two existing testing methods. One method is to take a sample and add water for testing. This method not only produces a large discrepancy between the test data and the actual situation, but also cannot be used for online testing. The other method is to insert a pH meter into the cellar mud for testing. However, the pH meter probe is relatively fragile and has a short lifespan, making it impossible to perform continuous testing over a long period of time.

[0006] ⑵ The existing testing of cellar mud lacks systematic ecological testing, and it is impossible to obtain effective ecological indicator data, resulting in the inability to fit the ideal curves of various cellar mud indicators for wine production. Utility Model Content

[0007] In view of the above problems, the present invention provides a pH meter specifically for detecting the acidity of pit mud, which aims to improve at least one of the problems mentioned in the background art.

[0008] A pH meter specifically for detecting the acidity of pit mud comprises a pH meter body and a probe connected to the bottom end of the pH meter body. The pH meter body is covered with an outer shell. The pH meter specifically for detecting the acidity of pit mud also comprises a filter and protection sleeve, the upper end of which is connected to the outer shell. The filter and protection sleeve consists of a connecting upper section and a functional lower section. The probe is located in the functional lower section. The functional lower section has a functional lower section lower end surface, which serves as the lower seal of the functional lower section. The functional lower section and the functional lower section lower end surface form a detection cavity. The functional lower section and the functional lower section lower end surface both allow liquid to enter and exit the detection cavity while excluding particulate matter.

[0009] Optionally, the functional lower section and the lower end surface of the functional lower section are both 304 stainless steel filter meshes.

[0012] Optionally, a plurality of pins are evenly arranged on a side of the lower end surface of the functional lower section facing away from the detection cavity.

[0013] The utility model also provides a quick detection device for cellar mud ecological indicators.

[0014] A quick detection device for cellar mud ecological indicators comprises a pH meter, a conductivity sensor, a nitrogen, phosphorus, potassium sensor, an oxidation-reduction potential sensor, a moisture sensing ball, and a computer for collecting detection information. The pH meter, conductivity sensor, nitrogen, phosphorus, potassium sensor, oxidation-reduction potential sensor, and moisture sensing ball each have a detection end located within the cellar mud.

[0032] Example 1

[0033] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the overall structure of a pH meter specifically used for pit mud acidity detection provided by the utility model. Figure 2 This is a schematic diagram of the main view of the filter and protection sleeve of the utility model. Figure 3 This is a schematic diagram of the cross section of the filter and protection sleeve. Figure 4 The utility model is a schematic diagram of a 304 stainless steel filter screen.

[0034] A pH meter specifically for detecting the acidity of pit mud comprises a pH meter body and a probe 1 connected to the bottom end of the pH meter body. The pH meter body is covered with an outer shell 2. The pH meter specifically for detecting the acidity of pit mud also comprises a filter and protective sleeve 3. The upper end of the filter and protective sleeve 3 is connected to the outer shell 2. The filter and protective sleeve 3 consists of a connecting upper section 4 and a functional lower section 5. The probe 1 is located in the functional lower section 5. The lower end surface 6 of the functional lower section is a sealed type. The functional lower section 5 and the lower end surface 6 of the functional lower section form a detection cavity 7. The functional lower section 5 and the lower end surface 6 of the functional lower section both allow liquid to enter and exit the detection cavity 7 while excluding particulate matter.

[0035] By connecting the upper section 4 and the functional lower section 5, during use, the functional lower section 5 is inserted under the pit mud, allowing the liquid in the mud to enter the detection chamber 7. Once the liquid accumulates in the detection chamber 7, online long-term monitoring of changes in the acidity of the mud can begin. Because there are no particulates in the detection chamber 7, the probe 1 does not need to come into contact with solid particles, greatly extending the probe's lifespan. Furthermore, because online testing can be performed, separate sampling is not required, and the test data can directly reflect the actual conditions of the pit mud.

[0036] Those skilled in the art should know that the pH meter body, probe 1, and shell 2 are existing technologies, and the pH meter body, probe 1, and shell 2 form the existing pH meter. Since the pH meter body, probe 1, shell 2 and their connection and installation methods are existing technologies, they will not be described in detail here.

[0037] In one or more specific embodiments of the present invention, the functional lower section 5 and the lower end surface 6 of the functional lower section are both 304 stainless steel filter screens.

[0038] In one or more specific embodiments of the present invention, the mesh size of the 304 stainless steel filter is 150-250 meshes.

[0039] In one or more specific embodiments of the present invention, in order to improve the structural strength of the functional lower section 5 and the lower end surface 6 of the functional lower section, reinforcing ribs are provided on the functional lower section 5 and the lower end surface 6 of the functional lower section.

[0040] In one or more specific embodiments of the present invention, the upper connecting section 4 can be fixedly connected to the outer shell 2, or can be detachably connected to the outer shell 2. When detachably connected, it can be achieved by, for example, providing an external thread on the outer shell 2 and an internal thread on the upper connecting section 4, or it can be connected in other detachable ways.

[0041] In one or more specific embodiments of the present invention, the connecting upper section 4 and the functional lower section 5 can be integral or detachable. When detachable, the section where the functional lower section 5 is connected to the connecting upper section 4 is provided with an internal thread, and the connecting upper section 4 is provided with an external thread. After connection, the connection position is sealed.

[0042] In one or more specific embodiments of the present invention, in order to facilitate insertion, a plurality of pins 8 are evenly arranged on the side of the lower end surface 6 of the functional lower section facing away from the detection cavity 7 .

[0043] Example 2

[0044] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the utility model of a quick detection device for ecological indicators of cellar mud.

[0045] A quick detection device for cellar mud ecological indicators comprises the pH meter, conductivity sensor, nitrogen, phosphorus and potassium sensor, redox potential sensor, moisture sensing ball and a computer of Example 1. Detection ends of the pH meter, conductivity sensor, nitrogen, phosphorus and potassium sensor, redox potential sensor and moisture sensing ball are respectively located in the cellar mud. The pH meter, conductivity sensor, nitrogen, phosphorus and potassium sensor, redox potential sensor, moisture sensing ball and a PLC are also located. Signal output ends of the pH meter, conductivity sensor, nitrogen, phosphorus and potassium sensor, redox potential sensor and moisture sensing ball are connected to the computer, which is used to collect detection information.

[0046] By selectively detecting pH, conductivity, nitrogen, phosphorus and potassium, redox potential and moisture, a systematic ecological detection of cellar mud is formed, and pH meters, conductivity sensors, nitrogen, phosphorus and potassium sensors, redox potential sensors and moisture sensing balls are distributed in the cellar mud for online detection. By connecting the detection output signal to a computer, online detection data is collected to form effective ecological indicator data. After collecting long-term data and combining it with the raw liquor production and quality data, the ideal curves of various cellar mud indicators can be fitted for wine production.

[0047] Since pH, conductivity, nitrogen, phosphorus, potassium, redox potential and moisture are detected quickly, the readings start to be displayed 3 minutes after insertion into the pit mud, and the accuracy is high (the error is less than 10%). Therefore, the rapid detection device has fast detection and high accuracy.

[0048] Those skilled in the art should understand that how to distribute pH meters, conductivity sensors, nitrogen, phosphorus and potassium sensors, redox potential sensors, and moisture sensing balls in the cellar mud, and how to transmit and convert the signals sensed by pH meters, conductivity sensors, nitrogen, phosphorus and potassium sensors, redox potential sensors, and moisture sensing balls into computer-recognizable technologies are existing technologies and will not be described in detail here.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
