Description

Technical Field

[0001] The utility model relates to the technical field of rice wine processing, in particular to a fermentation box which is convenient for secondary water addition after saccharification of rice wine. Background Art

[0002] In the process of preparing rice wine, an appropriate amount of water needs to be added for the second time after saccharification. The purpose is to promote the growth and reproduction of yeast by adjusting the concentration of the solution after saccharification, thereby achieving alcohol fermentation. Specifically, adding water can reduce the sugar concentration after saccharification, create an environment more suitable for yeast metabolism, and help yeast convert sugar into alcohol and carbon dioxide. In addition, appropriate water addition can also ensure temperature control during the fermentation process, prevent abnormal fermentation temperature rise caused by excessively high sugar concentration, and ensure the smooth progress of fermentation.

[0003] In the existing water adding process, the amount of water to be added is usually obtained by manual weighing, and then the lid is opened for secondary water adding. The process has the following problems:

[0004] On the one hand, opening the lid may lead to bacterial contamination or other contamination, which may affect the quality of the fermented rice wine;

[0005] On the other hand, after the glutinous rice in the box is saccharified or fermented, there may be a certain air pressure inside, which may lift up the lid and make it difficult to open the lid, or after opening the lid, gas may spray out and cause the solution to splash. Utility Model Content

[0036] Embodiment 1 provides a fermentation box for facilitating secondary water addition after saccharification of rice wine. The fermentation box detachably locks the box cover 2 and the box body 1 through a pressing buckle 3. After locking, the box cover 2 and the box body 1 form a sealed fit through a sealing mechanism 4, which is suitable for an anaerobic fermentation environment of rice wine.

[0037] A mounting groove 5 is provided on the top of the box cover 2, and the mounting groove 5 is communicated with the box body 1 through a through hole 6. An elastically telescopically matched ventilation mechanism 7 is installed in the mounting groove 5, and the ventilation mechanism 7 forms a releasable sealing match with the notch of the mounting groove 5. Carbon dioxide will be generated in the fermentation process of rice wine, and the air pressure inside the box body 1 will continue to increase. The air pressure in the box will also generate pressure on the ventilation mechanism 7. When the internal air pressure of the box body 1 is too high, the ventilation mechanism 7 will be lifted up, so that a gap will appear between the ventilation mechanism 7 and the notch of the mounting groove 5, and automatic deflation and pressure relief will be performed. When deflation and pressure relief are completed, the elastic potential energy generated by the elastic telescopic match is converted into dynamic potential energy, and the ventilation mechanism 7 is pulled to form a sealing match with the notch of the mounting groove 5 again, thereby achieving pressure control and preventing excessive pressure in the box body 1;

[0038] The ventilation mechanism 7 is provided with a water passing mechanism 8, through which water can be added to the through hole 6 and the box body 1 without opening the cover, so as to facilitate secondary water addition after saccharification to control the sweetness and alcohol content to form a unique flavor, and also reduce the impact of opening the cover on fermentation.

The annular protrusion 401 can be detachably embedded in the sealing groove 403, and the sealing groove 403 forms a sealing fit with the box mouth through the sealing ring 402.

[0040] Embodiment 2 provides a specific structure of the sealing mechanism 4, the box cover 2 and the box body are connected to each other through the annular protrusion 401 and the sealing groove 403, and when the connection is completed, a fixed fit is formed by pressing the buckle 3, and the box cover 2 squeezes the sealing ring 402 to form a seal.

[0041] As a preferred embodiment 3, the annular protrusion 401 is coaxially concentric with the box opening of the box body 1, and the sealing groove 403 is coaxially concentric with the annular protrusion 401. This ensures docking during installation, thereby ensuring sealing.

[0042] As a preferred embodiment 4, the ventilation mechanism 7 includes a baffle plate 701, which is supported on the top of the slot of the mounting slot 5 and covers the slot of the mounting slot 5. A number of springs 702 are provided between the baffle plate 701 and the bottom of the mounting slot 5. The baffle plate 701 forms an elastic telescopic fit with the bottom of the mounting slot 5 through the springs 702. The springs 702 are always in a stretched state, and the water passing mechanism 8 is provided in the middle position of the baffle plate 701.

[0043] Example 4 provides a specific structure of the ventilation mechanism 7, and the spring 702 in the stretched state always provides a pulling force to pull the baffle plate 701 toward the installation groove 5, so that the baffle plate 701 covers the notch of the installation groove 5 to form a sealing fit. When the internal air pressure is too high, the baffle plate 701 will be pushed open to automatically release the pressure. After the pressure release is completed, it will be sealed again by the spring 702.

[0044] As a preferred embodiment 5, a sealing gasket is coaxially and concentrically provided at the bottom of the shielding plate 701. The shielding plate 701 forms a sealing fit with the notch of the installation groove 5 through the sealing gasket when pressed, thereby ensuring the sealing performance.

[0045] As a preferred embodiment 6, the springs 702 are arranged at equal intervals around the through hole 6, one end of each spring 702 is fixedly matched with the bottom of the installation groove 5, and the other end of the spring 702 is fixedly matched with the bottom of the baffle plate 701 to ensure the stability of the elastic telescopic fit.

[0046] As a preferred embodiment 7, the shielding plate 701 is concentric and coaxial with the installation groove 5, and the size of the shielding plate 701 is larger than the size of the installation groove 5, thereby ensuring the shielding effect and improving the sealing performance.

[0047] As a preferred embodiment 8, there are six springs 702 to ensure the stability of elastic expansion and contraction.

[0048] As a preferred embodiment 9, the water passage mechanism 8 includes a water pipe 802, which passes through the baffle plate 701 and forms a fixed fit with the baffle plate 701. One end of the water pipe 802 located in the installation groove 5 is embedded in the through hole 6, and the other end of the water pipe 802 located outside the installation groove 5 is detachably fixedly installed with a water valve 801.

When the internal air pressure of the box body 1 is too high, the ventilation mechanism 7 will be lifted up, so that a gap will appear between the ventilation mechanism 7 and the notch of the mounting groove 5, and automatic deflation and pressure relief will be performed. When deflation and pressure relief are completed, the elastic potential energy generated by the elastic telescopic match is converted into dynamic potential energy, and the ventilation mechanism 7 is pulled to form a sealing match with the notch of the mounting groove 5 again, thereby achieving pressure control and preventing excessive pressure in the box body 1;

[0056] The ventilation mechanism 7 is provided with a water passing mechanism 8, through which water can be added to the through hole 6 and the box body 1 without opening the cover, so as to facilitate secondary water addition after saccharification to control the sweetness and alcohol content to form a unique flavor, and also reduce the impact of opening the cover on fermentation.
