Description

Technical Field

[0001] The utility model relates to the technical field of wine making, in particular to a fermentation cellar. Background Art

[0002] The cellar is a container used to hold grain for fermentation. It is a type of fermentation container in the process of liquor brewing, that is, the place where grain is saccharified and fermented. In layman's terms, the cellar is a pit dug on the ground, and the grain buried in the pit is saccharified and fermented. The fermented grain is dug out and distilled to obtain liquor. The construction of this "pit" pays attention to innate conditions such as terrain and soil, and the materials used vary from place to place.

[0003] During the fermentation process, fermentation yellow water will be produced. When there is too much yellow water, the grain will be submerged, and the solid-state fermentation will become a semi-solid fermentation mode, causing the lees to be too wet and the wine yield to be particularly low. Therefore, the yellow water needs to be discharged in time. The traditional way of discharging the yellow water is to scoop it out manually, which is inconvenient to operate. The inner wall of the cellar is covered with cellar mud. When the user loads or unloads materials, it is easy to scratch the cellar mud, thereby affecting the service life of the cellar mud. For this reason, we propose a fermentation cellar. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, a fermentation cellar includes a cellar body 2. The cellar is to some extent built on the ground, rather than dug out from the flat ground, because the low temperature of the cellar determines the fermentation temperature. The more appropriate the fermentation temperature, the better the fermentation effect. If it is dug out from the flat ground, the low temperature of the cellar is much lower than that of the cellar built from the flat ground. A sealing cover 1 is fixedly installed on the upper surface of the cellar body 2, and a yellow water discharge structure 3 is fixedly installed on the lower surface of the cellar body 2. Yellow water is the liquid flowing out during solid-state fermentation and is a by-product of solid-state fermentation. Yellow water contains not only rich alcohol, aldehyde, acid and ester substances, but also rich organic acids, starch, reducing sugars, yeast autolysates and other nutrients, and contains a large number of brewing microorganisms and aroma precursors that have been domesticated for a long time. A protective structure 4 is embedded and installed inside the cellar body 2;

[0022] The cellar body 2 includes an outer cellar body 201, an embedded groove 202, an inner cellar body 203, a filter screen 204, a first drainage groove 205, and a second drainage groove 206. The upper surface of the outer cellar body 201 is provided with embedded grooves 202 near the edge, and the embedded grooves 202 are four groups. The lower surface of the outer cellar body 201 is provided with a second drainage groove 206 in the middle. The inner cellar body 203 is embedded and installed inside the outer cellar body 201. The inner cellar body 203 is the cellar mud. As a carrier of microorganisms, the cellar mud plays a very important role in the fermentation process. The importance of the structure is to provide a suitable living environment for the fermentation of wine-making microorganisms, and the microbial population provides a continuous source of power for the production of liquor in the process of complex material energy metabolism in the cellar. A first drainage ditch 205 is opened in the middle of the lower surface of the inner tank body 203, and a filter screen 204 is embedded in the first drainage ditch 205; the yellow water drainage structure 3 includes a water storage tank 301, a water pump 302, a water outlet pipe 303, and a water inlet pipe 304. The water storage tank 301 is embedded with a water inlet pipe 304 on one side surface, and a side end of the water inlet pipe 304 is provided. A water pump 302 is fixedly installed at the mouth, and a water outlet pipe 303 is fixedly installed on one side surface of the water pump 302; the cellar body 2 and the yellow water discharge structure 3 are fixedly installed on the lower surface of the outer tank body 201 through the water storage tank 301 and are located in the middle position, and the sealing cover 1 and the cellar body 2 are fixedly installed on the upper surface of the outer tank body 201 through the sealing cover 1; the protective structure 4 includes a connecting plate 401, an embedded plate 402, and a protective plate 403. The lower surface of the connecting plate 401 is fixedly installed with an embedded plate 402 near the edge. The embedded plates 402 are four groups, and the embedded plates 402 serves as a limit for the protective plate 403. The lower surface of the connecting plate 401 is located on the adjacent surface of the embedded plate 402, and the protective plate 403 is fixedly installed. The protective plate 403 is divided into four groups, and the bottom of the protective plate 403 is an inclined surface, which is convenient for the protective plate 403 to be better inserted between the grain and the inner pool body 203; the cellar body 2 and the protective structure 4 are embedded in the embedded groove 202 through the embedded plate 402, and the protective plate 403 is embedded and installed in the inner pool body 203. The connecting plate 401 is located on the upper surfaces of the outer pool body 201 and the inner pool body 203.

[0023] It should be noted that the utility model is a fermentation cellar. When in use, the protective structure 4 needs to be placed inside the cellar body 2. After the material is unloaded, the protective structure 4 is taken out and the sealing cover 1 is covered for fermentation. The yellow water produced during the fermentation process is discharged by the yellow water discharge structure 3. After the fermentation is completed, the protective structure 4 is embedded into the interior of the cellar body 2 and then the material is unloaded; the embedded plate 402 is embedded into the embedded groove 202, and the protective plate 403 is lowered downward through the connecting plate 401 above the outer cellar body 201, so that the protective plate 403 is close to the inner wall of the inner cellar body 203, and then the material is unloaded. The height of unloading is more than the actual required height. A small part is released to fill the gap when the protective plate 403 is taken out later. After the material is unloaded, the protective structure 4 is taken out. The yellow water generated during the fermentation process can be discharged into the water storage tank 301 through the filter screen 204 inside the first drainage trough 205 and the second drainage trough 206, and after the fermentation is completed, the water pump 302 will pump out the yellow water through the water inlet pipe 304 and the water outlet pipe 303. When unloading, the embedded plate 402 can be embedded into the embedded groove 202 again, so that the protective plate 403 is located between the grain and the inner tank body 203. Unloading at this time is beneficial to protecting the inner tank body 203 and reducing the friction on the inner tank body 203.

[0024] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
