Description

Technical Field

[0001] This utility model relates to a fermentation tank, specifically a fermentation tank for processing bayberry wine, and belongs to the technical field of bayberry fermentation equipment. Background Technology

[0002] The brewing process of bayberry wine is unique. During fermentation, the solid parts of the bayberry pulp float to the surface due to the buoyancy of carbon dioxide gas, forming a thick layer of fruit caps. If not handled promptly, the inside of the fruit caps will not have sufficient contact with the wine, preventing the effective extraction of anthocyanins, tannins, and other coloring and flavor compounds from the bayberries, thus affecting the color and taste of the finished wine. Furthermore, the accumulation of fruit caps can cause localized overheating, easily leading to the growth of unwanted microorganisms and producing undesirable flavors. Traditional manual cap-pressing methods are not only labor-intensive but also pose a risk of contamination due to the open operation.

[0003] In existing technologies, some fermentation tanks use a circulating rinsing method, which involves pumping the bottom liquid to the top for spraying. However, for hardened and thick bayberry caps, the sprayed liquid often creates a channel effect, making it impossible to achieve uniform and effective wetting and breaking up of the bayberry caps. Utility Model Content

[0004] Based on the above background, the purpose of this utility model is to provide a fermentation tank for processing bayberry wine, which solves the technical problems of uneven maceration of bayberry caps and low extraction efficiency in the prior art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A fermentation tank for processing bayberry wine includes a tank body, a skinning assembly, a gas pulse stirring assembly, and a circulation pump. The skinning assembly includes a spray pipe, a liquid outlet pipe, and a return pipe. The spray pipe is horizontally arranged in the upper part of the inner cavity of the tank body and has multiple spray holes facing the lower part of the inner cavity of the tank body. The liquid outlet pipe is located outside the tank body and one end is connected to the lower part of the inner cavity of the tank body. The other end of the liquid outlet pipe is connected to the inlet of the circulation pump. The outlet of the circulation pump is connected to the spray pipe through the return pipe. The gas pulse stirring assembly is located in the lower part of the inner cavity of the tank body and includes a gas distributor and a flow guide hood. The gas distributor has multiple gas outlet holes. The flow guide hood is fixedly installed above the gas distributor and has an inverted U-shaped cross-section. The top of the flow guide hood has an opening facing the upper part of the inner cavity of the tank body.

[0007] By combining a top-down rinsing component with a bottom-up gas pulse stirring component, the gas pulse stirring component gathers energy through a guide hood to break the fruit cap with airflow, and the rinsing component gently soaks the broken fruit cap, forming a method of breaking first and then rinsing, thus achieving efficient and gentle fruit cap treatment for bayberry fermentation.

[0008] Preferably, the tank body includes a cylindrical upper tank body and a conical lower tank body. The bottom of the upper tank body is provided with an air inlet, which is connected to the gas distributor. The bottom of the lower tank body is provided with a liquid outlet, which is connected to the liquid outlet.

[0009] Preferably, the gas pulse stirring assembly is located at the bottom of the inner cavity of the upper tank.

[0010] Preferably, the bottom of the lower tank section is also provided with a wine outlet.

[0011] Preferably, both the gas distributor and the flow guide are annular.

The sidewall of the outer ring side cover is inclined toward the direction of the inner ring side cover, and the sidewall of the inner ring side cover is inclined toward the direction of the outer ring side cover. The space between the top of the outer ring side cover and the top of the inner ring side cover forms the top opening of the flow guide.

[0013] Preferably, the gas distributor has multiple support members on its surface, and the flow guide is fixedly connected to the gas distributor through the support members.

[0014] Preferably, the return pipe is equipped with a pressure gauge and a breather valve, and the pressure gauge and the breather valve are connected in parallel.

[0015] The pressure gauge is used to monitor the pressure inside the tank in real time, and the breather valve serves as a safety guarantee, automatically releasing pressure or replenishing air when the pressure is abnormal to prevent damage to the tank.

[0016] Preferably, the side wall of the tank is provided with a sampling port.

[0017] Setting up a sampling port allows for convenient extraction of wine samples for testing key indicators without contaminating the overall material.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This invention relates to a fermentation tank for processing bayberry wine. By combining a skin-drenching assembly with a gas pulse stirring assembly equipped with a flow guide, it achieves efficient processing of the bayberry fermentation caps by first breaking them and then rinsing them. The gas pulse stirring assembly uses the flow guide to gather gas energy, which can gently break and turn the floating caps.

In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0029] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention discloses a fermentation tank for processing bayberry wine, including a tank body 1, a skinning assembly 2, a gas pulse stirring assembly 3, and a circulation pump 4.

[0030] The tank body 1 is made of stainless steel and consists of a cylindrical upper tank body 11 and a conical lower tank body 12, which are welded together to form the tank body 1.

[0031] The rinsing assembly 2 is used to wet the floating fruit caps with wine, and it includes a spray pipe 21, a liquid outlet pipe 22, and a return pipe 23. For example... Figure 3 As shown, the spray pipe 21 is horizontally arranged in the upper part of the inner cavity of the tank 1, in a cross shape or parallel arrangement. The spray pipe 21 has multiple spray holes 211 facing the lower part of the inner cavity of the tank 1. The liquid outlet pipe 22 is located outside the tank 1, with one end connected to the lower part of the inner cavity of the tank 1, and the other end connected to the inlet of the circulation pump 4. The outlet of the circulation pump 4 is connected to the spray pipe 21 through the return pipe 23.

[0032] The gas pulse stirring assembly 3 is located in the lower part of the inner cavity of the tank body 1, specifically, it is located at the bottom of the inner cavity of the upper section of the tank body 11. The gas pulse stirring assembly 3 includes a gas distributor 31 and a flow guide 32. In this embodiment, both the gas distributor 31 and the flow guide 32 are annular to accommodate the circular cross-section of the tank body 1. The gas distributor 31 is an annular porous tube with multiple rows of small air outlets 311 on its surface. The flow guide 32 is fixedly positioned above the gas distributor 31, and has an inverted U-shaped cross-section, with an opening at the top of the flow guide 32 facing upwards towards the inner cavity of the tank body 1. Specifically, as shown... Figure 4As shown, the flow guide 32 includes an outer ring side cover 322 and an inner ring side cover 323. The sidewall of the outer ring side cover 322 is inclined toward the inner ring side cover 323, and the sidewall of the inner ring side cover 323 is inclined toward the outer ring side cover 322. The gap between the top of the outer ring side cover 322 and the top of the inner ring side cover 323 forms the top opening 321 of the flow guide 32. The surface of the gas distributor 31 is provided with a plurality of support members 33, and the flow guide 32 is fixedly connected to the gas distributor 31 through the support members 33.

[0033] The upper tank 11 has an air inlet 13 at its bottom, through which a gas distributor 31 is connected to an external compressed air source pipeline. The lower tank 12 has a liquid outlet 14 at its bottom, connected to a liquid outlet pipe 22. The lower tank 12 also has a wine outlet 15 at its bottom for drawing clarified wine. Additionally, the lower tank 12 has a sludge discharge port (not shown in the figure) at its bottom for discharging yeast sludge and fruit pomace.

[0034] To ensure the safety and controllability of the production process, a pressure gauge 231 and a breather valve 232 are installed on the return pipe 23, connected in parallel. The pressure gauge 231 is used to monitor the pressure inside the tank in real time, while the breather valve 232 serves as a safety guarantee, automatically releasing pressure or replenishing gas in case of abnormal pressure to prevent damage to the tank 1. In addition, a sampling port 16 is provided on the side wall of the tank 1, which allows for convenient extraction of wine samples for testing key indicators without contaminating the overall material.

[0035] The working principle of the fermentation tank used for processing bayberry wine is as follows:

[0036] In the early stages of bayberry wine fermentation, bayberry berries and sugar syrup are added to tank 1. As yeast acts, it produces a large amount of carbon dioxide, causing the solid pulp to rise to the surface and form a dense fruit cap.

[0037] The gas pulse stirring component 3 is activated, and an external gas source injects high-pressure gas into the gas distributor 31 in a pulsed manner. The gas is ejected at high speed from the gas outlet 311. In the narrow flow channel formed by the flow guide shroud 32, the gas mixes violently with the surrounding wine, forming a low-density gas-liquid mixture, which is then ejected upwards, impacting the entire annular area of ​​the fruit cap, breaking it up and turning it over, so that it is re-immersed in the wine.

[0038] After the gas pulse stirring assembly 3 is started, the skin-covering assembly 2 is started, and the circulation pump 4 starts working. The wine liquid rich in yeast and flavor substances, which has been preliminarily mixed in the lower part of the tank 1, is pumped to the top spray pipe 21 through the liquid outlet pipe 22 and the return pipe 23, and then sprayed onto the surface of the loosened fruit caps through the spray holes 211.

[0039] The fermentation tank used for processing bayberry wine greatly improves the extraction efficiency. By breaking the fruit before rinsing, it solves the problem of uneven contact between the inside and outside of the fruit cap, allowing the anthocyanins, tannins and aromatic substances in the bayberry pulp to dissolve to the maximum extent, resulting in a bayberry wine with a fuller taste and a richer aroma.

[0040] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
