Description

Technical Field

[0001] This utility model relates to the field of winemaking technology, specifically to a sampling device for winemaking. Background Technology

[0002] After the grapes have been crushed and destemmed, the grape juice and skins are placed together in the mash, and fermentation and maceration occur simultaneously. Higher temperatures will deepen the color of the wine, but temperatures above 35 degrees Celsius may inactivate the yeast. Therefore, it is necessary to regularly sample and test the wine to detect key substances and improve the quality of wine fermentation.

[0003] In the prior art, patent document CN220289094U discloses a sampling device for wine fermentation, including a sampling tube with a capacity mark fixedly installed on its outer wall. A drain outlet is fixedly fitted onto the outer wall of the sampling tube near its upper end, and a valve is rotatably installed on the drain outlet. A handle is fixedly connected to the upper part of the sampling tube away from the drain outlet, and an air hole is fixedly opened on one side of the handle. An inlet tube is fixedly fitted to the middle of the bottom plate of the sampling tube, and multiple filter holes are fixedly opened on the outer wall of the inlet tube near its upper end. A sealing cap is fixedly connected to the upper end face of the inlet tube, and a piston rod is slidably fitted onto the middle of the sealing cap. A sealing piston is fixedly connected to the lower end of the piston rod. This sampling device for wine fermentation can conveniently filter grape skins during the sampling process, achieve quantitative sampling, and prevent sample solution spillage, making it practical.

[0004] To address the issue that existing sampling devices, where the inlet and outlet are integrated, can cause spillage even with slight shaking when too much sample is taken, the current technology uses a piston rod to lift a sealed piston, drawing the wine through the inlet pipe. However, this method still presents the problem of difficulty in controlling the sampling volume, thus reducing the practicality of the sampler. Utility Model Content

[0028] Example 1

[0029] like Figure 1-5 As shown, this utility model provides a sampling device for winemaking, including a sampling unit 1 and a pressure applying unit 2 disposed on the outer surface of the sampling unit 1 for applying pressure. The sampling unit 1 includes a sampling component and an adjusting component disposed inside the sampling component. The pressure applying unit 2 includes an air extraction component disposed on the outer surface of the sampling unit 1 and a connecting component disposed on the outer surface of the sampling unit 1. The sampling component includes a sampling tube 11, the outer surface of which is provided with scale lines 111. A sampling needle 12 is fixedly connected to the bottom of the sampling tube 11. An expansion needle 13 is disposed inside the sampling needle 12. A threaded bolt 131 is disposed on the outer surface of the expansion needle 13. The expansion needle 13 is detachably connected to the inner wall of the sampling needle 12 through the threaded bolt 131. A handle 14 is fixedly connected to the outer surface of the sampling tube 11. A finger ring 15 is disposed on the outer surface of the handle 14. The adjusting component includes a sealing... The outer surface of the sealing cap 16 is detachably connected to the top of the sampling tube 11. The inner wall of the sealing cap 16 is threaded with a threaded rod 17, and the bottom of the threaded rod 17 is rotatably connected to a rubber stopper 18. The outer surface of the rubber stopper 18 is slidably connected to the inner wall of the sampling tube 11. When using the sampling device for winemaking, if quantitative sampling is required, the rubber stopper 18 can be moved inside the sampling tube 11 by rotating the threaded rod 17. At the same time, the position of the rubber stopper 18 inside the sampling tube 11 can be adjusted in conjunction with the scale line 111. After adjustment, the user can hold the handle 14 and insert the sampling needle 12 into the wine. If the length of the sampling needle 12 needs to be increased during use, the extension needle 13 can be installed inside the sampling needle 12. Finally, the pressure unit 2 is used to change the air pressure inside the sampling tube 11, thereby completing the adsorption of the wine.

[0030] Example 2

[0031] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the suction assembly includes a mounting ring 21, the inner wall of which is fixedly connected to the outer surface of the sampling tube 11, an airbag device 22 is fixedly connected to the outer surface of the mounting ring 21, a one-way air inlet valve 221 is provided on the outer surface of the airbag device 22, and the connecting assembly includes a connecting pipe 23, one end of which is fixedly connected to the output end of the airbag device 22, and the other end of which is fixedly connected to a one-way valve 24, the outer surface of which is fixedly connected to the outer surface of the sealing cap 16. The surface is provided with a sealing plug 25, and the output end of the one-way valve 24 is fixedly connected to a telescopic tube 26. The other end of the telescopic tube 26 is connected to the inside of the rubber stopper 18. When it is necessary to reduce the internal pressure of the sampling tube 11, the airbag device 22 is pressed, and in conjunction with the one-way air inlet valve 221, connecting tube 23, one-way valve 24 and telescopic tube 26, the internal pressure of the sampling tube 11 is evacuated, thereby assisting in the absorption of wine and facilitating sampling. After the sampling is completed, when it is necessary to release the wine, the sealing plug 25 can be removed to release the internal pressure of the sampling tube 11, thereby facilitating the release of the wine.

[0032] The working principle of this sampling device for winemaking will be explained in detail below.

[0033] like Figure 1-5 As shown, when using the sampling device for winemaking, if quantitative sampling is required, the rubber stopper 18 can be moved inside the sampling tube 11 by rotating the threaded rod 17. At the same time, the position of the rubber stopper 18 inside the sampling tube 11 can be adjusted in conjunction with the scale line 111. After adjustment, the user can hold the handle 14 and insert the sampling needle 12 into the wine. If the length of the sampling needle 12 needs to be increased during use, the extension needle 13 can be installed inside the sampling needle 12. Finally, the pressure unit 2 is used to change the air pressure inside the sampling tube 11. By pressing the airbag device 22, in conjunction with the one-way air inlet valve 221, connecting pipe 23, one-way valve 24 and telescopic pipe 26, air is drawn into the sampling tube 11 to assist in the absorption of wine and facilitate sampling. After sampling is completed, when it is necessary to release the wine, the sealing plug 25 can be removed to release the pressure inside the sampling tube 11, thus facilitating the release of the wine.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
