Description

Technical Field

[0001] The invention relates to the technical field of food processing, and in particular to a closed tidal alternating anaerobic and aerobic fermentation device and a method. Background Art

[0002] Winemaking is made by soaking, boiling, cooling, and mixing various types of molds and yeasts with various types of grain raw materials, or by crushing, juicing, adjusting ingredients, sterilizing, and mixing various types of molds and yeasts with fruit raw materials. The prepared mash is then sealed in a vat for fermentation. After the mash is sealed in the vat, when the surface of the inner surface is covered with a wine cap, the sealed vat cover is opened and repeatedly raked to break the surface wine cap to discharge the fermented carbon dioxide gas and stir the mash to cool it down, so that good wine can be brewed.

[0003] Traditional fermentation technology has the following problems:

[0004] 1. In the traditional fermentation process, it is easy to cause the fermented mash to be contaminated and soured due to incomplete disinfection of the container or the need to open the lid for stirring and raking to cool down and damage the surface of the wine cap. When the carbon dioxide gas is discharged from the wine cap, the bacteria in the air are brought into the fermented mash.

[0005] Second, in the traditional wine fermentation process, it is difficult to create a fermentation environment where fermentation bacteria can ferment in both a microaerobic and anaerobic environment at different time periods and perform fermentation in a cross-fertilization process;

[0006] 3. In the traditional wine fermentation process, it is difficult to create a fermentation environment in which fermentation bacteria can be fermented in different time periods, and both nitrification aerobic fermentation and denitrification anaerobic fermentation must be carried out alternately;

It is necessary to stir the mash with a rake to break the cap on the surface of the mash to discharge the carbon dioxide gas and stir the mash to cool it down.

[0008] 5. In the traditional wine fermentation process, the fermented mash needs to be stirred and raked, which causes the fermented yeast hyphae to break and die in large numbers;

However, the present invention can obviously be implemented in a variety of other ways different from this description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific implementation method.

The fermentation chamber 110 is used to store fermented mash, and the collection chamber 120 is used to store mash precipitated from the mash in the fermentation chamber 110.

[0060] Specifically, the fermentation equipment provided by the present invention can be used for wine fermentation, such as rice wine, fruit wine, rice wine, Shanlan wine and other wine fermentation, and can also realize the fermentation process of other foods, such as soy sauce, yogurt, vinegar, etc., without limitation here.

[0061] The following explanation is given using wine making as an example, without any limitation.

[0062] Specifically, a partition 190 is provided between the fermentation chamber 110 and the collection chamber 120 to separate them. The partition 190 divides the chamber in the tank body 10 into the fermentation chamber 110 and the collection chamber 120 respectively. The partition 190 has an opening. A mash filter 191 is detachably installed at the opening of the partition 190.

[0063] The mash filter screen 191 can be detachably connected to the partition 190 through a plurality of threaded connectors or buckles, so that when the mash filter screen 191 is used for a long time and becomes clogged, it can be removed and cleaned.

[0064] The tank body 10 is also provided with a control pipe group 20, which is preferably arranged at the bottom of the tank body 10. The tank body 10 is provided with two outlets at the bottom, one of which is connected to the ascending pipe 210, and the other is connected to the descending pipe 220. One end of the ascending pipe 210 is connected to the collecting chamber 120, and the other end is inserted into the tank body 10 and connected to the fermentation chamber 110. The ascending pipe 210 is provided with a first control member 211, which is used to transport the liquid in the collecting chamber 120 to the fermentation chamber 110 through the ascending pipe 210, so as to increase the liquid level in the fermentation chamber 110 and discharge the gas in the fermentation chamber 110, so that the fermented material in the fermentation chamber 110 is in an anaerobic fermentation environment.

[0065] In one embodiment, the first control component 211 is an ascending pump, and a first bypass valve 212 is also provided on the ascending pipeline 210. When the first bypass valve 212 and the ascending pump are opened at the same time, the ascending pump can transport the liquid in the collecting chamber 120 to the fermentation chamber 110. The first bypass valve 212 can be a one-way valve to prevent the liquid in the fermentation chamber 110 from flowing back into the collecting chamber 120 through the ascending pipeline 210.

[0066] One end of the downpipe 220 is connected to the collecting chamber 120 , and the other end is inserted into the tank body 10 and connected to the fermentation chamber 110 . A second control member 221 is provided on the downpipe 220 for controlling the on and off of the downpipe 220 .

The second bypass valve can be a solenoid valve, which is not limited here and is within the protection scope of the present application.

[0068] The ascending pipeline 210 and the descending pipeline 220 can be operated independently, or one end can be connected to form a confluence pipe 230 (such as Figure 2 Specifically, one end of the ascending pipeline 210 and the descending pipeline 220 converge to form a confluence pipe 230, and the other ends of the ascending pipeline 210 and the descending pipeline 220 are respectively connected to the collecting chamber 120. One end of the confluence pipe 230 is connected to the fermentation chamber 110, and the other end of the confluence pipe 230 is connected to the collecting chamber 120 via the ascending pipeline 210 or the descending pipeline 220.

[0070] That is, the length extension direction of the ventilation cannula 130 is consistent with the length extension direction of the tank body 10, so that the gas can quickly reach different height areas in the fermentation chamber 110 through the ventilation cannula 130. The number of ventilation cannula 130 can be two, three or more. Figure 1 Four are used as an example for illustration, but the number is not limited. Multiple ventilation cannulas 130 can be connected to each other or placed independently. One end of the ventilation cannulas 130 can be connected to the top or bottom of the tank body 10, or can be inserted along the axial direction of the tank body 10 after the tank body 10 is filled with mash.

[0071] At least one first barb 140 is disposed at one end of the ventilation cannula 130 close to the top of the tank body 10 . The at least one first barb 140 constitutes at least one group of distribution units 141 . Each group of distribution units 141 is axially arranged around the ventilation cannula 130 .

[0072] Preferably, when multiple groups of distribution units 141 are provided at one end of the ventilation cannula 130 , the distribution units 141 are arranged axially at intervals along the ventilation cannula 130 , and each group of distribution units 141 includes at least two first barbs 140 , and at least two first barbs 140 are arranged circumferentially at intervals around the ventilation cannula 130 .

[0073] The length extension direction of the first barb 140 is toward the bottom of the fermentation chamber 110 and the angle between the first barb 140 and the main body of the ventilation cannula 130 is set, and the angle can be 30 degrees, 45 degrees, etc., which is not limited here.

[0074] Reference Figure 1 Along the axial direction of the ventilation cannula 130, three groups of distribution units 141 are distributed at intervals, and each group of distribution units 141 includes two first barbs 140. Figure 1 The three groups of distribution units 141 are only examples, and two, four or more groups of distribution units 141 may also be set. Each group of distribution units 141 may also include two first barbs 140, three first barbs 140 or multiple first barbs 140, etc., which are not limited here and are all within the protection scope of this application.

[0075] The tank body 10 is also provided with a seepage assembly 150, which includes a liquid inlet pipe 151 and at least one seepage insert pipe 152 connected to the liquid inlet pipe 151. The liquid inlet pipe 151 extends from the outside of the tank body 10 to the fermentation chamber 110. The seepage insert pipe 152 is connected to the liquid inlet pipe 151 and is located in the fermentation chamber 110. Each seepage insert pipe 152 is provided with at least one second barb 153. Specifically, there can be multiple ventilation insert pipes 130 and seepage insert pipes 152, and multiple ventilation insert pipes 130 and seepage insert pipes 152 can be arranged to extend outward from the center of the tank body 10 in multiple circles.

[0076] A hole may be provided on the tank body 10, and a liquid inlet pipe 151 is inserted into the hole and extends into the fermentation chamber 110. The liquid inlet pipe 151 is sealed and connected to the tank body 10, for example, a sealing gasket may be provided to prevent the external gas of the tank body 10 from entering the fermentation chamber 110. One end of the seepage cannula 152 is connected to the liquid inlet pipe 151, and the liquid inlet pipe 151 can infiltrate liquid into the inside of the seepage cannula 152 and introduce the liquid into the fermented material through the seepage cannula 152.

[0077] As for the second barb 153, the structure of the second barb 153 is consistent with that of the first barb 140, and the second barb 153 may also include at least one group of distribution units 141, and at least one group of distribution units 141 is arranged at intervals along the axial direction of the infiltration cannula 152. Each group of distribution units 141 includes at least one second barb 153, and at least one second barb 153 is arranged at intervals around the outer circumference of the infiltration cannula 152. Figure 1 Three groups of distribution units 141 are also used as an example for explanation, and each group of distribution units 141 includes two second barbs 153. However, the number of distribution units 141 and the number of second barbs 153 included in each distribution unit 141 are only given as examples and are not limited to this, and are all within the scope of protection of this application.

[0078] The seepage cannula 152 and the ventilation cannula 130 are both porous tubes. The seepage cannula 152 is arranged near the top of the fermentation chamber 110, and the length of the seepage cannula 152 is less than the length of the ventilation cannula 130. The structures of the seepage cannula 152 and the ventilation cannula 130 are both cylindrical, hollow inside, and multiple through holes are distributed on the surface. The liquid inlet pipe 151 can quickly transport the nutrient solution to different height areas in the fermentation chamber 110 through the seepage cannula 152, and the newly input fresh air in the fermentation chamber 110 can reach the mash areas at different positions through the ventilation cannula 130. The length of the seepage cannula 152 is less than the length of the ventilation cannula 130, which can achieve the effect of uniform feeding without occupying too much space in the fermentation chamber 110.

[0079] In one embodiment, an ozone disinfection mechanism 40 is further included, and the ozone disinfection mechanism 40 is respectively connected to the fermentation chamber 110 and / or the collection chamber 120 through two second connecting pipes 410. Further, the two second connecting pipes 410 are each provided with a switch valve for controlling the opening and closing of each second connecting pipe 410.

[0080] The tank body 10 is also provided with an air outlet pipe group 180, and two branches of the air outlet pipe group 180 are respectively connected to the fermentation chamber 110 and the collection chamber 120. Before the fermentation chamber 110 is put into the fermentation chamber 110, the switch valves on the two second connecting pipes 410 and the ozone disinfection mechanism 40 are opened, so that the ozone disinfection mechanism 40 unidirectionally passes high-concentration ozone into the fermentation chamber 110 and the collection chamber 120 for disinfection, and the concentration is set at about 50 mg per cubic meter, and the sterilization time can be 30-50 minutes.

[0081] A feed pipe 160 is provided at the top of the tank body 10, and the feed pipe 160 is connected to the fermentation chamber 110; correspondingly, a discharge pipe 170 is provided at the bottom of the tank body 10, and the discharge pipe 170 is connected to the collection chamber 120, and an output pump 171 is also provided on the discharge pipe 170. The fermented mash to be fermented can be injected into the fermentation chamber 110 from the feed pipe 160, and then the brewed wine can be collected through the discharge pipe 170 after the winemaking is completed.

[0082] Please continue to refer to Figure 1 The tank body 10 is also provided with a temperature regulating layer 50, such as a constant temperature refrigeration belt. The temperature regulating layer 50 is sleeved on the outside of the tank body 10 and there is a storage space 510 between the tank body 10. The temperature regulating layer 50 is provided with a liquid inlet conduit 520 connected to the storage space 510, and the temperature regulating medium is injected or discharged into the storage space 510 through the liquid inlet conduit 520. The temperature regulating medium can be a liquid or a gas, and water is used as an example for illustration, but it is not limited to this. For example, the temperature needs to be controlled at 22-30 degrees Celsius in the early stage of fermentation, and the temperature needs to be controlled at 12-16 degrees Celsius in the middle and late stages of fermentation. The control of different temperatures can be achieved by introducing water of different temperatures into the storage space 510 through the liquid inlet conduit 520 to regulate the temperature in the tank body 10 to meet the temperature requirements at different times.

[0083] In one embodiment, an air intake mechanism 30 is also provided on the tank body 10, and the air intake mechanism 30 includes a molecular filtration unit 310, an ultraviolet disinfection unit 320 and two first connecting pipes 330 connected in sequence. One end of the two first connecting pipes 330 is connected to the ultraviolet disinfection unit 320, and the other end is connected to the fermentation chamber 110 and the collection chamber 120 respectively. The external gas enters the fermentation chamber 110 and / or the collection chamber 120 respectively through the molecular filtration unit 310, the ultraviolet disinfection unit 320 and the corresponding first connecting pipes 330 in sequence.

[0084] Specifically, the air first enters the molecular filtration unit 310 for filtration, and the pore size of the molecular filtration unit 310 is set to be less than 0.1 microns, so that most of the bacteria with a pore size of about 0.45 microns can be filtered out. The air filtered by the molecular filtration unit 310 enters the ultraviolet disinfection unit 320, and after being disinfected by the ultraviolet disinfection unit 320, the sterile fresh air is formed and enters the first connecting pipe 330, and then enters the fermentation chamber 110 or the collection chamber 120 through the first connecting pipe 330. The waste gas generated by the fermentation can be discharged from the tank body 10 through the outlet pipe group 180.

[0085] According to the above structural description, the process of switching between anaerobic and aerobic fermentation in the closed tidal alternating anaerobic and aerobic fermentation equipment of the present invention is as follows:

[0086] When the fermentation chamber 110 is at the high tide stage, the first control member 211 can be opened, and the liquid in the collection chamber 120 flows back into the fermentation chamber 110, causing the liquid level in the collection chamber 120 to drop. At this time, the sterilized fresh air can be injected into the lower chamber to balance the air pressure. At the same time, the liquid level in the fermentation chamber 110 rises to form a positive pressure, so that the fermentation waste gas generated by the fermentation material in the fermentation chamber 110 is squeezed out through the air outlet pipe group 180, and the excess heat is also discharged out of the tank body 10. At this time, the entire fermentation material in the fermentation chamber 110 is submerged by the rising mash, and the anaerobic fermentation stage is formed in the fermentation chamber 110.

[0087] When the fermentation chamber 110 is in the low tide stage, the second control member 221 is opened, and the mash in the fermentation chamber 110 flows into the collection chamber 120 through the second control member 221 by gravity, and the carbon dioxide in the collection chamber 120 is discharged. At this time, negative pressure is formed in the fermentation chamber 110 due to the drop in liquid level, and sterilized fresh air is input into the fermentation chamber 110 from the first connecting pipe 330, so that the mash in the fermentation chamber 110 can enter the aerobic fermentation stage.

[0088] By using the first control element 211 and the second control element 221, tides can be realized to control the switching between aerobic fermentation and anaerobic fermentation of the fermentation material in the fermentation chamber 110 in different time periods.

[0089] Specifically, when the mash in the fermentation chamber 110 rises, the mash infiltrates into the mash from the holes of the seepage cannula 152 and the ventilation cannula 130, and the fermentation waste gas is squeezed out from the porous spaces in the seepage cannula 152 and the ventilation cannula 130, and the mash is in an anaerobic fermentation environment. When the mash in the fermentation chamber 110 falls, fresh air infiltrates into the mash from the porous spaces in the seepage cannula 152 and the ventilation cannula 130, and the mash is in an aerobic fermentation environment.

[0090] Setting the seepage cannula 152 and the ventilation cannula 130 as porous tubes is also beneficial in that during the aerobic fermentation process, the overheated temperature can be dissipated from the porous spaces of the seepage cannula 152 and the ventilation cannula 130 to achieve a cooling effect.

[0091] The barbs are provided on the seepage cannula 152 and the ventilation cannula 130 so that when the tank body 10 is filled with fermented grains, the fermented grains can be added into the fermentation chamber 110 along the barbs, and when the fermented grains are fermenting and the liquid level in the fermentation chamber 110 drops, the surface of the fermented grains can drop along the barbs. When the fermented grains form a surface fermentation cap during fermentation, the liquid level of the fermented grains rises and overflows the surface fermentation cap, the barbs can hang the fermentation cap to prevent it from floating up, which is beneficial for squeezing out the fermentation waste gas without opening the tank body 10, and the fermentation cap is beneficial as a source of nutrition for maintaining yeast in the later stage of fermentation.

[0092] After fermentation has been going on for a period of time, the newly made yeast starter material is crushed and filtered and added into the fermentation chamber 110 through the liquid inlet pipe 151 as a new nutrient source or a new flavor component to maintain the activity of the yeast.
