Description

Technical Field

[0001] The utility model relates to an auxiliary mechanism for wine fermentation equipment, in particular to a material circulation mechanism for wine fermentation equipment. Background Art

[0002] Fermentation is one of the most important processes in the wine making process, and its fermentation effect directly affects the quality of the wine. Wine is fermented with skin and seeds. The CO2 produced during the alcohol fermentation process will lift the skin and seeds, causing the fermented mash to be divided into two layers. The upper layer is a non-flowing dry matter layer called the "cap" formed by the skin, seeds and pulp, which contains about 20% of liquid matter. The lower layer is a liquid fermentation liquid formed by juice and a small amount of pulp and skin residue. The volume ratio of the two parts is about 50% each.

[0003] In order to improve the fermentation effect, it is necessary to use the corresponding material circulation mechanism to circulate and pump the lower liquid fermentation liquid to the upper skin and residue layer to spray the upper skin and residue layer. Since the lower liquid fermentation liquid contains a small amount of pulp and skin and residue, the lower liquid fermentation liquid can only be circulated and pumped under the premise of filtration. The material circulation mechanism used in existing wine fermentation equipment is generally a pumping system with a backwashing function. Since it is impossible to accurately judge whether the filter end is blocked, it can only rely on manual judgment and manual decision when to backwash the filter end. Not only does it require a dedicated person to supervise the material circulation mechanism of the wine fermentation equipment, but also the pumping pump often continues to operate when the filter end is blocked due to misjudgment. In severe cases, the pumping pump may even be damaged.

[0004] Therefore, the research purpose of the utility model is to design a material circulation mechanism for wine fermentation equipment that can effectively and accurately determine whether the filter end is blocked, and can conveniently backwash the filter end, so that the lower liquid fermentation liquid in the fermentation process can be continuously and evenly pumped to the upper part of the fermentation tank to spray the upper skin and residue layer.

[0010] The pumping mechanism comprises a pump for pumping liquid in the isolation tube to the plurality of nozzles for spraying, the liquid inlet end of the pump is connected to the first feed pipe and the second feed pipe in parallel outward through the first feed valve and the second feed valve, the liquid inlet end of the first feed pipe is connected to the isolation tube, the liquid inlet end of the second feed pipe is connected to the bottom side of the fermentation tank and is covered with a corresponding filter; the discharge end of the pump is connected to one side of the feed end of the plurality of nozzles through a delivery pipe equipped with a discharge valve, a corresponding backflush pipe is connected between the delivery pipe on the feed end side of the discharge valve and the first feed pipe on the feed end side of the first feed valve, and a corresponding backflush valve is fixedly installed on the backflush pipe;

[0016] A plurality of the nozzles are connected to corresponding liquid distribution annular pipes in an annular array, and the liquid distribution annular pipes are connected to the delivery pipe.

[0017] Advantages of the utility model:

[0018] 1) Since the upper part of the isolation tube of the utility model is connected to the upper sealing plate through a bellows, when the filter plate is blocked, it can move upward after being pressurized, thereby driving the isolation tube upward. In this way, the upward movement distance of the isolation tube can be determined according to the position change of the position sensor, thereby determining whether the filter plate is blocked; and after determining that the filter hole of the filter plate is blocked, the first feed valve and the discharge valve can be controlled to be closed, and the second feed valve and the backwash valve can be controlled to be opened to backwash the filter plate.

[0025] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0026] refer to Figure 1-3, a material circulation mechanism for wine fermentation equipment, comprising:

[0027] A plurality of nozzles 1 are installed in a circular array on the upper part of the corresponding fermentation tank 2;

[0028] The filter 3 comprises an upper sealing plate 301 installed on the bottom side of the fermentation tank 2, the bottom side of the upper sealing plate 301 is downwardly connected to a corresponding isolation pipe 303 through a corrugated pipe 302, and a filter plate 304 provided with a plurality of filter holes is fixedly installed at the bottom of the isolation pipe 303;

[0029] The pumping mechanism 4 comprises a pumping pump 401 for pumping the liquid in the isolation tube 303 to the plurality of nozzles 1 for spraying. The liquid inlet end of the pumping pump 401 is connected to the first feed pipe 402 and the second feed pipe 403 in parallel outwardly through the first feed valve 5 and the second feed valve 6. The liquid inlet end of the first feed pipe 402 is connected to the isolation tube 303, and the liquid inlet end of the second feed pipe 403 is connected to the bottom side of the fermentation tank 2 and is covered with a corresponding filter 7. The discharge end of the pumping pump 401 is connected to one side of the feed end of the plurality of nozzles 1 through a delivery pipe 404 equipped with a discharge valve 8. A corresponding backflush pipe 405 is connected between the delivery pipe 404 on the feed end side of the discharge valve 8 and the first feed pipe 402 on the feed end side of the first feed valve 5, and a corresponding backflush valve 9 is fixedly installed on the backflush pipe 405.

[0030] The position sensor 10 is installed at the bottom side of the isolation tube 303. The position sensor 10 is electrically connected to the corresponding electric controller 11. The working process of the liquid pump 401, the first feed valve 5, the second feed valve 6, the discharge valve 8, and the backflush valve 9 is controlled by the electric controller 11. The position sensor 10 in this embodiment adopts a proximity sensor.

[0031] Since the upper part of the isolation tube 303 of the utility model is connected to the upper sealing plate 301 through the bellows 302, when the filter plate 304 is blocked, it can move upward after being pressurized, thereby driving the isolation tube 303 upward. In this way, the upward movement distance of the isolation tube 303 can be determined according to the position change of the position sensor 10, thereby determining whether the filter plate 304 is blocked; and after determining that the filter hole of the filter plate 304 is blocked, the first feed valve 5 and the discharge valve 8 can be controlled to be closed, and the second feed valve 6 and the backwash valve 9 can be controlled to be opened, so as to backwash the filter plate 304.

[0032] A corresponding isolation tube 12 is coaxially fixedly sleeved on the outer side of the isolation tube 303, and a plurality of corresponding liquid permeable holes are evenly distributed on the side wall of the isolation tube 12. The upper end of the isolation tube 12 is sealed and connected to the bottom side of the upper sealing plate 301, and the lower end of the isolation tube 12 extends to the lower side of the isolation tube 303 and is sealed and connected to the corresponding lower sealing plate 13.

[0033] The isolation cylinder 12 is used to initially isolate the large particles of pulp in the lower liquid fermentation liquid, and then the filter plate 304 is used to filter the small particles of pulp and peel residue. The filtered lower liquid fermentation liquid is pumped to the nozzle 1 for spraying under the action of the liquid pump 401, so as to improve the practical effect of the utility model.

[0034] The bottom of the isolation cylinder 12 is connected outwardly to a discharge pipe 15 equipped with a one-way valve 14. An annular limiting plate 16 is fixedly installed on the inner wall of the isolation cylinder 12, and an isolation plate 17 adapted to the annular limiting plate 16 is fixedly installed on the outer wall of the isolation tube 303. The isolation plate 17 is arranged in a bucket shape with a narrow top and a wide bottom, and the bottom of the isolation plate 17 is located at the lower side of the annular limiting plate 16 and is spaced from the annular limiting plate 16. The liquid permeable holes on the isolation cylinder 12 are distributed on the upper side of the annular limiting plate 16.

[0035] Since the isolation plate 17 is in a bucket shape with a narrow top and a wide bottom, and the bottom of the isolation plate 17 is located below the annular limiting plate 16 and is spaced therefrom, the fermentation liquid outside the isolation cylinder 12 can smoothly enter the bottom side of the isolation cylinder 12 to ensure that the pumping and drainage of the lower liquid fermentation liquid can be carried out smoothly; and during backwashing, the isolation plate 17 will move upward after being pressurized and abut against the annular limiting plate 16, so that the backwashing liquid and the blockage after backwashing can only be discharged in one direction along the discharge pipe 15, so that the blockage after backwashing can be discharged to the outside of the filter plate 304, so as to further greatly improve the practical effect of the utility model.

[0036] A plurality of the nozzles 1 are connected to corresponding liquid distribution annular pipes 18 in an annular array, and the liquid distribution annular pipes 18 are connected to the delivery pipe 404 .

[0037] When the grape material is fermented by the fermentation equipment, the grape material after stem removal and crushing and the corresponding yeast are fed into the fermentation tank; under the corresponding fermentation temperature conditions, the grape material begins the fermentation process; the CO2 generated during the fermentation process will lift the skin and seeds in the grape material, so that the mash in the fermentation tank is divided into an upper skin and residue layer and a lower liquid fermentation liquid according to the height. The utility model is mainly used to pump the lower liquid fermentation liquid in the fermentation process to the upper part of the upper skin and residue layer to spray the upper skin and residue layer. The spraying process includes the following specific steps:

[0038] S1, the liquid pump is started to pump the lower liquid fermentation liquid to the spray head for spraying, so as to spray the skin residue layer suspended on the upper part of the liquid material;

[0039] S2, monitoring the position of the isolation tube in real time through a position sensor. When the position sensor detects that the isolation tube moves upward by a distance exceeding L1, it is determined that the filter hole of the filter plate is blocked, and the first feed valve and the discharge valve are closed, and the second feed valve and the backwash valve are opened to backwash the filter plate;

[0040] S3, after the backwashing time reaches t1, the second feed valve and the backwash valve are closed, and the first feed valve and the discharge valve are opened, and the lower liquid fermentation liquid is continuously pumped to the upper skin residue layer for spraying.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
