Description

Technical Field

[0001] The utility model relates to the field of wine processing equipment, in particular to a tank sampling valve device with anti-blocking and nitrogen protection functions and a wine fermentation tank. Background Art

[0002] During the wine fermentation process, samples must be taken regularly from the fermentation tank sampling valve to test various physical and chemical indicators such as the mash's temperature, specific gravity, alcohol content, and residual sugar. Due to the characteristics of grapes, the mash often contains substances such as skins and seeds, which can easily clog the sampling valve, causing significant trouble for sampling and testing. Once clogged, forceful measures, such as using thin wire or other metal materials, must be used to poke it open. However, using metal materials can cause metallic tarnish and turbidity in the wine, affecting its quality.

[0003] During the wine production process, the wine is always at risk of oxidation, so it cannot be separated from the protection of inert gas. Nitrogen and carbon dioxide are the most widely used inert gases. Because nitrogen is easier to prepare, most companies mainly use nitrogen in actual production. Usually, most company technicians use nitrogen pipes to inject nitrogen into the tank from the upper tank opening to replace the gas and achieve the purpose of protecting the wine from oxidation. However, because nitrogen has a lower density than air, it floats upwards, making this protection method less effective. Therefore, the best way to protect the wine with nitrogen is to fill the tank from the bottom upwards.

[0004] Based on this, the present utility model is proposed. Utility Model Content

[0030] First embodiment

[0031] like Figure 1 As shown, this embodiment provides a tank body 1 sampling valve 2 device with anti-clogging and nitrogen protection functions. The tank body 1 sampling valve 2 device is arranged on the tank body 1 of the fermentation tank, and includes a connecting part and a sampling part.

[0032] Specifically, the connecting portion is a cylindrical body with a hollow interior. One end of the connecting portion is connected to the tank body 1, and the other end is connected to the sampling portion. The connecting portion and tank body 1 are detachably connected. Threads are provided on the outer wall of the connecting portion, and matching threaded holes are provided on the tank body 1. The threads and threaded holes connect the connecting portion and tank body 1. The other end of the connecting portion is fixedly connected to the sampling portion.

[0033] The sampling portion is also a cylindrical body with a cavity inside, one end of which is connected to the connecting portion and the other end is provided with an opening. The sampling valve 2 has an end surface and a movable rod connected thereto. The sampling valve 2 inserts the movable rod into the inner cavity of the sampling portion through the opening. The movable rod is provided with threads, and the opening of the sampling portion is also provided with matching threads. The sampling portion realizes the movement of the movable rod through the threaded connection between the movable rod and the opening.

[0034] A sampling port is provided at the bottom of the side wall of the sampling portion, which is connected to a sampling valve funnel 5. The connection method is as follows: the sampling port and the sampling valve funnel 5 are both provided with joints, and the sampling port and the sampling valve funnel 5 are connected through the joints and fastened with a quick-connect clamp 3. To prevent wine leakage, a sealing gasket 4 is also provided at the joint.

[0035] The sampling valve funnel 5 is in a truncated cone shape, and the diameter of the end connected to the sampling port is larger than the end away from the sampling port. By setting the sampling valve funnel 5 in a truncated cone shape, samplers with different diameters can be used to take samples from the sampling port.

[0036] In the present invention, the diameter of the movable rod is equal to the inner diameter of the sampling portion, and the wine flowing out of the connecting portion can be opened or closed, and the sampling port can be opened or closed by adjusting the position of the movable rod.

[0037] When sampling, the combined state of the tank body 1 and the sampling valve 2 of this embodiment is as follows: Figure 2 As shown, the operation method for sampling is as follows:

[0038] By operating the end face of the sampling valve 2 to rotate the movable rod, the position of the movable rod in the inner cavity of the sampling part is moved so that the movable rod is away from one end of the connecting part, and then the wine in the connecting part flows into the inner cavity of the sampling part. At the same time, due to the movement of the movable rod, the sampling port is opened, and the wine flows from the inner cavity of the sampling part into the sampling port. The operator puts the sampler on the outlet of the sampling funnel, and the wine enters the sampler from the sampling port, thereby realizing sampling.

[0039] Second embodiment

[0040] like Figure 1 As shown, this embodiment provides a tank body 1 sampling valve 2 device with anti-clogging and nitrogen protection functions. The tank body 1 sampling valve 2 device is arranged on the tank body 1 of the fermentation tank, and includes a connecting part and a sampling part.

[0041] Specifically, the connecting portion is a cylindrical body with a hollow interior. One end of the connecting portion is connected to the tank body 1, and the other end is connected to the sampling portion. The connecting portion and tank body 1 are detachably connected. Threads are provided on the outer wall of the connecting portion, and matching threaded holes are provided on the tank body 1. The threads and threaded holes connect the connecting portion and tank body 1. The other end of the connecting portion is fixedly connected to the sampling portion. The connecting portion connects the tank body 1 and the sampling portion, allowing liquid in the tank body 1 to flow into the sampling portion when needed.

[0042] The sampling portion is also a cylindrical body with a cavity inside, one end of which is connected to the connecting portion and the other end is provided with an opening. The sampling valve 2 has an end surface and a movable rod connected thereto. The sampling valve 2 inserts the movable rod into the inner cavity of the sampling portion through the opening. The movable rod is provided with threads, and the opening of the sampling portion is also provided with matching threads. The sampling portion realizes the movement of the movable rod through the threaded connection between the movable rod and the opening.

[0043] A sampling port is provided at the bottom of the sidewall of the sampling section. This port is connected to a nitrogen delivery assembly, which includes a connecting pipe and a nitrogen pipeline 7. One end of the connecting pipe has a connector, which connects to the sampling port and is also secured by a quick-connect clamp 3. The other end of the connecting pipe is connected to the nitrogen pipeline 7 via a pneumatic quick connector 6. To prevent nitrogen leakage, a sealing gasket 4 is also provided at the joint.

[0044] In the present invention, the diameter of the movable rod is equal to the inner diameter of the sampling portion, and the wine flowing out of the connecting portion can be opened or closed, and the sampling port can be opened or closed by adjusting the position of the movable rod.

[0045] The tank body 1 sampling valve 2 device of this embodiment is assembled in the following state when the sampling valve 2 is blocked by skin residue or the wine body needs nitrogen protection. Figure 3As shown, the operation method is as follows:

[0046] After the nitrogen delivery component is connected to the sampling port, first open the nitrogen pipeline 7 to allow nitrogen to enter the connecting pipeline from the nitrogen pipeline 7 and then enter the sampling port. Then open the sampling valve 2 switch of the sampling part. By controlling the pressure of the nitrogen in the nitrogen pipeline 7, the function of flushing the blockage or nitrogen protection of the wine body can be achieved. After the gas is filled, first close the switch of the sampling valve 2 and then turn off the nitrogen in the nitrogen pipeline 7.
