Description

Technical Field

[0001] The invention relates to the technical field of winemaking devices, and in particular to a white wine cellar mud protection and maintenance device and a white wine cellar pool. Background Art

[0002] Cellar mud is the foundation of Luzhou-flavor liquor brewing and an important carrier for the growth and reproduction of functional bacteria. Artificially cultivated high-quality cellar mud contains abundant microorganisms. These microorganisms can promote the production of caproic acid, the precursor of ethyl caproate, the main flavor substance of Luzhou-flavor liquor, and create favorable conditions for the esterification reaction of caproic acid to produce ethyl caproate. Only with high-quality cellar mud can the cellar ferment and produce high-quality Luzhou-flavor original liquor.

[0003] After the existing Luzhou-flavor liquor cellar pool wall and pool bottom are built, a layer of artificially cultivated old cellar mud needs to be laid on the pool wall and pool bottom. The pool bottom is often directly paved with old cellar mud, while the pool wall needs to be nailed with bamboo boards on the four sides of the pool wall. The bamboo boards protrude outwards about 5cm, and the bamboo boards are about 20cm apart from top to bottom and left to right. Each bamboo board is connected with hemp rope in a cross shape to facilitate the smearing of the cultivated old cellar mud on the pool wall and provide a fulcrum for the old cellar mud to adhere to the pool wall.

[0004] The existing pit mud protection and maintenance device has the following problems:

[0005] 1. It is easy to accidentally damage the pool wall and the bottom mud during operation: The existing strong-aroma cellar wall is built with bamboo boards and hemp ropes, and then the artificially cultivated high-quality cellar mud is smeared on the pool wall. On the one hand, it is difficult to tie the hemp rope evenly, resulting in difficulty in evenly applying the artificially cultivated high-quality cellar mud, and there is often inconsistency in thickness, which results in that after the cellar is put into use later, when the vehicle or excavator is digging the mash in the cellar, the protruding part of the cellar mud will be accidentally dug out and mixed into the mash. At the same time, when digging into the mash at the bottom of the pool, it is easy to mistakenly dig the cellar mud at the bottom of the pool together with the mash. When the mash is distilled on the steamer, the cellar mud smell will be brought into the wine, affecting the quality of the original wine of this batch; on the other hand, due to the reduction of cellar mud on the cellar wall and bottom, the quality of the next batch of wine will be affected; some liquor manufacturers will use high-quality artificial cellar mud for repairs to prevent affecting the quality of the next batch of wine, but this will increase the working time of the operators, and it will cost a lot of money to make artificial high-quality cellar mud, which also indirectly increases the production cost.

[0006] 2. The mud on the cellar wall is easy to fall off: the existing cellar wall is made of bamboo boards and hemp ropes. After a few years of use, the bamboo boards and hemp ropes corrode and the supporting force decreases. If the cellar is not properly maintained, a whole piece of cellar mud may age and fall off during the process of manual labor, driving or excavation, which not only affects the quality of the next batch of raw wine, but also increases the workload of repairing the cellar wall. At the same time, due to the aging of the cellar mud in many cellars, it is impossible to use bamboo boards to pierce them again during the repair process, because in the process of piercing, it may cause greater shedding in other adjacent areas, which brings great difficulties to the manufacturers of Luzhou-flavor liquor to repair the cellar mud on the cellar wall.

[0007] 3. Uneven and untimely maintenance of the cellars: On the one hand, the maintenance of the cellars is only carried out by spraying nutrient solution after the cellar is opened, and it is impossible to replenish nutrients for the cellar wall mud in time during the 45-70 day fermentation period of Luzhou-flavor liquor; on the other hand, even if some manufacturers sprinkle nutrient solution from the top of the cellar during the fermentation process, due to the inconsistent tightness of the mash around the cellar, the sprinkled nutrient solution is unevenly sprinkled on the cellar wall, some cellar walls receive excessive nutrient solution, and some cellar walls receive very little or even no nutrient solution, resulting in inconsistent quality of the cellar mud on the entire cellar wall, and even aging of some cellar mud, affecting the quality of the wine produced in the entire cellar; at the same time, the biggest disadvantage of pouring nutrient solution during the fermentation process is that air may enter the cellar along some gaps in the cellar wall, affecting the anaerobic fermentation of the mash in the cellar, affecting the output and quality of the fermented wine in this batch.

[0008] 4. The acid-producing capacity of the main functional bacteria in the cellar mud is not maximized: Since the optimal growth temperature of caproic acid bacteria, the main aroma-producing functional bacteria in the cellar mud, is 32-35°C, although caproic acid is also produced simultaneously in other temperature ranges, the acid-producing capacity is reduced, especially in the early and late stages of fermentation, when the temperature of the mash in the cellar is lower than 25°C, which affects the activity of caproic acid bacteria in the cellar, is not conducive to increasing the production of caproic acid, and further affects the production of ethyl caproate, the main aroma component in the original wine, thereby reducing product quality. Summary of the invention

[0009] The technical problems to be solved by the present invention are: reducing the operational risk of accidentally digging out the mud on the wall and bottom of a Luzhou-flavor liquor cellar during the process of removing the mud from the cellar; solving the problem that the mud on the cellar wall is easy to fall off after being used for many years; solving the problem that the maintenance of the cellar mud is not timely and sufficient; improving the activity of caproic acid bacteria, and further improving the production of ethyl caproate.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0040] Example 1

[0041] This embodiment discloses a white wine cellar mud protection and maintenance device, including a support frame 1, the support frame 1 includes a bottom frame 11 and a side frame 12, and the bottom frame 11 and the side frame 12 are detachably connected via a connector. A nutrient supply coil 3 and a temperature control coil 4 are arranged inside the side frame 12.

[0042] Support rods 2 are provided in both the bottom frame 11 and the side frame 12. The support rods 2 are arranged in the same manner on the bottom frame 11 and the side frame 12. As shown in the figure, the layout of the support rods 2 is described below using the bottom frame 11 as an example. The support rods 2 are arranged in a horizontal and vertical staggered manner, the number of the support rods 2 is three, and the area surrounded by the bottom frame is evenly divided into a 4×4 grid.

[0043] The width of the support rod 2 is smaller than the width of the bottom frame 11, and the support rod 2 is arranged near the bottom of the bottom frame 11. The support rod 2 is provided with through holes 21, and the through holes 21 are arranged at both ends and the middle section of the support rod 2.

[0044] A stainless steel mesh 13 is provided at the bottom of the bottom frame 11, and the stainless steel mesh 13 is fixed to the support rod 2 through the through hole 21 using a connecting piece such as a connecting rope or a pin. The support rod 2 is close to the bottom frame 11 so that the stainless steel mesh 3 can be better fixed to the bottom of the bottom frame 11. A stainless steel mesh 3 is also provided on the outside of the side frame 2, and the support rod 2 is arranged near the outside of the side frame 12 to better fix the stainless steel mesh 3. At the same time, the setting of the support rod 2 can form a placement space for the nutrient supply coil 3 and the temperature control coil 4 on the inner side of the outer frame. The aperture of the stainless steel mesh 3 is 0.5-1.5cm 2 .

[0045] The stainless steel mesh 3 on the outside of the side frame 12 can be of an integrated structure, that is, a whole stainless steel mesh 3 is used on the outside of the entire side frame 12 for unified installation and removal. The stainless steel mesh 3 can also be of a split structure, that is, a stainless steel mesh 3 is set corresponding to the outside of one or more grids, and each stainless steel mesh 3 is set independently. When a stainless steel mesh 3 is damaged, the stainless steel mesh 3 in the corresponding area can be replaced separately to avoid waste.

[0046] A pit mud protection bracket 14 is provided on the grid at the upper corner of the side frame 12. The pit mud protection bracket 14 is a honeycomb structure composed of a plurality of triangular brackets. A stainless steel fine mesh 15 is provided on the inner and outer sides of the pit mud protection bracket 14. The aperture of the stainless steel fine mesh 15 is 0.1-0.2 cm. 2 The areas in the cellar where the mud is easy to fall off are located at the top four corners. In this embodiment, the mud protection bracket 14 is arranged at the upper corner of the side frame 12 to provide sufficient support force for the mud while ensuring permeability to prevent the mud from falling off. In addition, the arrangement of the stainless steel mesh 3 and the stainless steel fine mesh 15 can effectively ensure the integrity of the mud wall, which is conducive to the uniform growth and reproduction of microorganisms in the mud in different areas.

The nutrient supply coils 3 are arranged on the outer ring of the temperature regulating coils 4.

[0049] The bottom frame 11 is also provided with the same nutrient supply coil 3 and temperature regulating coil 4 structure.

[0050] In this embodiment, nutrient solution can be pumped into the nutrient supply coil 3 by a liquid pump, and the nutrient solution can slowly penetrate into the cellar mud through the reverse osmosis membrane. During the fermentation process, it can provide nutrition to the microorganisms in the cellar mud at the required time, so that functional bacteria such as caproic acid bacteria in the cellar mud can grow and reproduce more robustly, and the ability of caproic acid bacteria to produce caproic acid is enhanced.

[0051] Since the temperature of the mash generally drops below 30°C in the middle and late stages of fermentation, the warm water circulation pump can be started at this time to pump 32-35°C warm water into the temperature regulating coil 4 in the middle and late stages of fermentation to heat the cellar mud on the pool wall and bottom, so that the aroma-producing main functional bacteria in the cellar mud can grow and multiply within the optimal temperature, thereby producing more caproic acid, which is further esterified to produce ethyl caproate, thereby improving the quality of the base liquor of Luzhou-flavor liquor.
