Description

Technical Field

[0001] The invention relates to the technical field of rice wine production, and more specifically, to fresh rice wine, and also to a production and transportation system for fresh rice wine. Background Art

[0002] Yellow rice wine is a unique alcoholic beverage, made mainly from glutinous rice, which is fermented with koji. During the brewing process, a variety of bacteria and microorganisms naturally form inside the yellow rice wine, which together give the yellow rice wine puree its unique umami flavor. However, the storage and transportation of yellow rice wine puree faces huge challenges. As it is very easy to become rancid and lose its flavor, directly storing and transporting yellow rice wine puree is not only difficult, but also easily leads to food safety issues.

[0003] In order to overcome this problem, rice wine must undergo sterilization during the production process. Traditionally, rice wine is pasteurized, which effectively kills most of the microorganisms in rice wine by controlling the temperature between 60 and 92 degrees for 5 to 30 minutes. However, long-term high-temperature treatment also brings a problem that cannot be ignored: it may destroy the flavor substances in rice wine, making the taste of rice wine mature and the original delicious taste greatly reduced. Moreover, the current rice wine still uses room temperature conditions during storage and transportation, which still cannot solve the problem of preserving the umami flavor substances in rice wine.

[0004] Therefore, although rice wine is very popular in the market, there is currently no rice wine product on the market that can maintain a fresh taste. This has become a major challenge facing the rice wine industry, and a new solution needs to be proposed to solve this problem. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] This embodiment discloses a fresh yellow wine, referring to Figure 1 As shown, the fresh rice wine is sterilized by high-temperature instant killing technology, and the rice wine pulp is sterilized at a relatively high temperature. While sterilizing, most of the substances and flavor substances can be retained, so that the fresh rice wine has a richer flavor and taste.

[0040] In addition, the fresh rice wine is refrigerated during the subsequent filling, storage, transportation and sales processes to maintain the fresh rice wine in a low temperature environment, extend the shelf life of the fresh rice wine, and maintain the flavor and taste of the fresh rice wine close to that of the original rice wine.

[0041] The fresh yellow rice wine in this embodiment uses yellow rice wine puree as the base wine, and preferably Shaoxing Jiafan wine or Shaoxing Huadiao wine that has been stored and aged for 1-3 years is selected. After the storage and aging are completed, the yellow rice wine puree is homogenized and blended to make the taste and flavor of the base wine consistent, thereby obtaining the base wine used for producing the fresh yellow rice wine. Alternatively, yellow rice wine of other years or types may also be used.

[0042] High temperature instant sterilization: Use rice wine puree as the base wine, sterilize it with a high temperature instant sterilization machine to obtain fresh rice wine. During the high temperature instant sterilization process, the sterilization temperature is 92-98℃, the sterilization time is 8-15s, and the temperature of the wine after high temperature sterilization is 1-5℃; generally, the sterilization temperature is controlled at 95℃, the sterilization time is controlled at 12s, and the temperature of the wine after high temperature sterilization is controlled at 4℃, which is the best.

[0043] The fresh rice wine in this embodiment, after completing the high-temperature instant killing, is refrigerated during the subsequent transportation and storage processes to maintain the temperature at 0-5°C, thereby preventing the temperature from rising and causing bacterial growth in the fresh rice wine, extending the shelf life of the fresh rice wine, and maintaining the freshness of the rice wine during transportation and sales. The fresh rice wine is filled and transported through a special production and transportation system to avoid the threat of contamination during the process.

[0044] This embodiment combines the high-temperature instant killing technology with the low-temperature refrigeration technology to obtain fresh rice wine with richer flavors, and keeps the fresh rice wine in a low-temperature environment after production, which can prevent the growth of bacteria in the wine and avoid the problem of sourness and loss of taste of the rice wine during storage and transportation, and can continuously maintain the taste and freshness of the fresh rice wine.

[0045] Embodiment 2

[0046] This embodiment discloses a production and transportation system for fresh yellow rice wine, which can be applied to the production, transportation and storage of the fresh yellow rice wine in the first embodiment.

[0047] In this embodiment, the fresh rice wine is filled and transported by a production and transportation system, wherein the production and transportation system uses filling barrels to fill and transport the fresh rice wine. The fresh rice wine is filled into the filling barrels, and in the subsequent transportation and storage processes, the filling barrels are used as containers. The fresh rice wine will not be in a container that comes into contact with gas, thereby reducing the possibility of the rice wine being contaminated with bacteria, thereby extending the shelf life of the fresh rice wine.

[0048] Reference Figure 2 As shown, the filling barrel includes a barrel body and a wine spear, the wine spear is fixedly connected to the barrel mouth of the barrel body, the wine spear includes a valve body, the valve body includes a gas channel and a liquid channel, a wine storage space is formed in the barrel body, a flow guide pipe is arranged in the barrel body, one end of the flow guide pipe is connected to the liquid channel, and the other end extends into the wine storage space in the barrel body. The flow guide pipe can be used to allow the wine in the wine storage space to enter and exit.

[0049] The gas channel is connected to the inner cavity of the barrel, and gas can be introduced into the barrel through the gas channel to increase pressure. When the wine is discharged, the air pressure of the barrel is adjusted through the gas channel, and the fresh rice wine in the bag is squeezed out of the guide tube by the air pressure.

[0050] Before filling, the CIP cleaning system is used to clean the filling machine, pipelines and other components to keep the parts that come into contact with the wine clean during storage and transportation to avoid the threat of bacterial contamination to the wine.

[0051] During the sales process, vending machines capable of low-temperature storage can be used for sales. It is also necessary to keep the wine in a suitable low-temperature environment during the short storage period to avoid the deterioration of fresh rice wine.

[0052] Embodiment 3

[0053] This embodiment discloses a production and transportation system for fresh yellow rice wine, which can be applied to the production, transportation and storage of the fresh yellow rice wine in the first embodiment.

[0054] In this embodiment, the fresh rice wine is filled and transported by a production and transportation system, wherein the production and transportation system uses filling barrels to fill and transport the fresh rice wine. The fresh rice wine is filled into the filling barrels, and in the subsequent transportation and storage processes, the filling barrels are used as containers. The fresh rice wine will not be in a container that comes into contact with gas, thereby reducing the possibility of the rice wine being contaminated with bacteria, thereby extending the shelf life of the fresh rice wine.

[0055] Reference Figure 3 As shown, the filling barrel includes a barrel body 1, a bag body 2 and a wine spear 3. The wine spear 3 is fixedly connected to the barrel mouth of the barrel body 1. The wine spear 3 includes a valve body, and the valve body includes a gas channel and a liquid channel 5. The bag body 2 is arranged in the barrel body 1, and the inner cavity of the bag body 2 is the wine storage space. The bag mouth of the bag body 2 is connected to the liquid channel 5 of the valve body, and the gas channel connects the space between the barrel body 1 and the bag body 2. A flow guide tube 4 is arranged in the bag body 2, and the first end of the flow guide tube 4 is connected to the liquid channel 5, and the second end extends into the bag body 2. The flow guide tube 4 is used for the liquid in the bag body 2 to enter and exit.

[0056] The valve body can be adjusted to open the gas channel and the liquid channel 5 respectively. In addition, the bag body 2 is used to fill fresh rice wine, and the space between the barrel body 1 and the bag body 2 is used to store gas, and the gas pressure is used to control the inflow and outflow of the wine in the bag body 2.

[0057] During filling, a relatively high air pressure is first introduced into the space between the barrel body 1 and the bag body 2. The air pressure can flatten the bag body 2 and squeeze out the air inside the bag body 2. Then, the liquid channel 5 of the valve body is connected to the pipeline of the wine liquid to reduce the air pressure between the barrel body 1 and the bag body 2. The bag body 2 will expand from the flattened state and, with the help of the pressure of the wine liquid, the rice wine will be sucked into the bag body 2 at the same time, thereby realizing the filling of the rice wine.

[0058] When dispensing the wine, the air pressure between the barrel body 1 and the bag body 2 is adjusted, the air pressure will gradually increase, and then the liquid channel 5 will be opened, and the fresh rice wine in the bag body 2 will be squeezed out by the air pressure, so that the fresh rice wine can be dispensed.

[0059] During the filling and dispensing process, the rice wine can be kept in a sterile state, and the wine does not come into direct contact with the air, which can prevent the wine from being contaminated. It can also prevent the raw rice wine from becoming sour and losing its taste during subsequent storage and transportation, and maintain the freshness of the raw rice wine for as long as possible.

[0060] Embodiment 4

[0061] This embodiment discloses a fresh yellow rice wine. On the basis of the first embodiment, it is further optimized. In the production process of the regenerated fresh yellow rice wine, the yellow rice wine pulp after high temperature instant killing is not filtered, and the yellow rice wine pulp is directly filled. Yellow rice wine is brewed from glutinous rice and wine yeast. After standing for a long time, sediment will appear. This is due to the coagulation of protein in the wine. Some bacterial colonies and flavor substances of the wine are attached to the particle sediment. The fresh yellow rice wine retains the particle impurities in the wine liquid, so that the flavor position therein can continue to be emitted into the fresh yellow rice wine, thereby making the fresh yellow rice wine have a flavor and taste close to that of the original wine, and maintain its freshness.

[0062] There are certain solid particles in fresh rice wine. Generally speaking, the content of solid particles is controlled within 5g in every 1L of fresh rice wine, which is beneficial to maintaining the taste of fresh rice wine and avoiding turbidity of the wine.

[0063] This embodiment also discloses a production and transportation system for fresh rice wine. Based on the second or third embodiment, the specific structure of the filling barrel is further designed to make it more suitable for the tubular shape and transportation of fresh rice wine. The production and transportation system uses the filling barrel to fill and transport the fresh rice wine.

[0064] The filtering device 6 added to the guide tube 4 inside the filling barrel of this embodiment can filter the fresh rice wine, so that the solid sediment in the fresh rice wine can be retained in the wine storage space, reducing the output of solid sediment when the wine is discharged, and keeping the discharged wine relatively clear.

[0065] Reference Figure 2 , Figure 3 As shown, a flow guide tube 4 is provided in the bag body 2 , a first end of the flow guide tube 4 is connected to the liquid channel 5 , and a second end extends into the bag body 2 , and the flow guide tube 4 is used for the liquid in the bag body 2 to enter and exit.

[0066] Reference Figure 4 As shown, a filtering device 6 is provided at the second end of the guide tube 4, and the filtering device 6 can provide input for the wine and the solid particles in the wine during filling, and can filter the output wine during discharging, and output relatively clear fresh rice wine.

[0067] The filter device 6 includes a sliding sleeve 61, a blocking cover 62 and a filter screen 66. The sliding sleeve 61 at least partially extends into the flow guide tube 4 and can slide along the length direction of the flow guide tube 4. The blocking cover 62 is fixedly connected to the end of the sliding sleeve 61. The blocking cover 62 is located outside the second end of the flow guide tube 4 and can cover and seal the second end of the flow guide tube 4. The slideway is limited by the blocking cover 62.

[0068] A connecting rod 7 is fixedly connected to the side of the cover plate facing the inside of the air guide pipe 4, and a linkage block 71 is fixedly connected to the end of the connecting rod 7 away from the cover plate. A limiting convex ring 74 is fixedly connected to the inner periphery of the air guide pipe 4, and a spring 73 is elastically pressed between the limiting convex ring 74 and the linkage block 71. The linkage block 71 is provided with a through hole 3 72; the spring 73 is used for elastically driving the connecting rod 7 to move toward the inside of the air guide pipe 4, and elastically maintaining the block and the second end of the air guide pipe 4 in a closed state of being pressed against each other.

[0069] The filter screen 66 is annular in structure, one end of the filter screen 66 is connected to the extension edge 64, and the other end of the filter screen 66 is connected to the outer periphery of the flow guide tube 4, and a filtering space is formed between the extension edge 64, the filter screen 66 and the outer wall of the flow guide tube 4. The filter screen 66 is made of a fabric woven material, has a relatively flexible state, and can effectively filter the particles in the rice wine to obtain relatively clean wine.

[0070] A through groove 63 is provided on the outer circumference of the sleeve 61, and the through groove 63 passes through the inner circumference and the outer circumference of the sleeve 61. When filling the wine, the pressure of the wine pushes the cover plate to move, and at the same time drives the sleeve 61 to extend out of the guide tube 4, until the through groove 63 of the sleeve 61 extends out of the guide tube 4. At this time, the through groove 63 of the guide tube 4 is connected to the filtering space. The filled wine is input from the guide tube, through the through groove 63 outside the sleeve 61, and input into the filtering space in the filter screen 1 66. The wine passes through the filter screen 1 66 and enters the wine storage space to realize wine storage.

[0071] A plurality of through holes 67 are provided on the cover plate, and an elastic valve sheet 68 is provided on the side of the cover plate facing the inner side of the flow guide tube 4. The elastic valve sheet 68 has a certain elasticity and can be elastically bent. The middle of the elastic valve sheet 68 is fixedly connected to the cover plate, and the outer peripheral part of the elastic valve sheet 68 can be elastically deformed and relatively elastically bent. In addition, a filter screen 69 is provided on the side of the cover plate facing away from the flow guide tube 4. The filter screen 69 covers the through holes 67 and filters the wine flowing through the filter screen 69.

[0072] During filling, the wine applies pressure to the elastic valve plate 68 on the inner side of the cover plate, and the elastic valve plate 68 can basically fit with the cover plate, cover and close the second through hole 67 on the cover plate, and close the second through hole 67. When discharging the wine, the wine storage space is subjected to air pressure, and the wine flows through the second filter screen 69, is filtered by the second filter screen 69, and then passes through the second through hole 67, applying pressure to the elastic valve plate 68, pushing the elastic valve plate 68 to deform and bend toward the inner side of the sliding sleeve 61, and the elastic valve plate 68 opens the second through hole 67, so that the relatively clear wine after filtration can be discharged from the guide tube 4, and fresh rice wine can be discharged.

[0073] Furthermore, the extension edge 64 protrudes from the outer wall of the flow guide tube 4 to have a certain width, and a plurality of through holes 65 are opened at the extension edge 64, and each through hole 65 is distributed in a substantially annular array. Moreover, the through hole 65 is connected to the filtering space inside the filter screen 66.

[0074] In addition, a cover 610 is fixedly connected to the side of the baffle 62 facing away from the flow guide tube 4. The cover 610 is a roughly spherical shell structure. The cover 610 covers the outside of the baffle plate and can cover the through hole 1 65, the through hole 2 67 and the filter screen 2 69. When the fresh yellow wine is discharged, the wine in the wine storage space first flows through the filter screen 1 66 and enters the filtering space inside the filter screen 1 66; then, the fresh yellow wine flows through the through hole 1 65 and enters the space between the cover 610 and the cover body from the filtering space; then, after being filtered by the filter screen 2 69, it enters the sliding sleeve 61 and the flow guide tube 4 from the through hole 2 67, and then is discharged along the flow guide tube 4.

[0075] By adopting the filtering device 6, during filling, the wine liquid and solid particles of the fresh yellow rice wine can be normally input into the wine storage space, so that the wine liquid in the wine storage space can always be in contact with the solid particles, maintain the exchange of flavors, and thus maintain the fresh state of the fresh yellow rice wine for a long time; and when discharging the wine, the fresh yellow rice wine can be filtered, so that the solid sediment in the fresh yellow rice wine can be retained in the wine storage space, reducing the output of solid sediment when discharging the wine, and keeping the wine relatively clear.

[0076] In addition, during the wine dispensing process, the fresh yellow wine first flows through the filtering space and contacts the solid particles in the filtering space, so that the wine can fully adhere to the flavor and taste carried by the solid particles, and then pass through the filtering treatment of the filter mesh 2 69, so that it has a sufficient flavor and taste before the wine is dispensed, and the wine can be kept clear. In addition, during the wine dispensing process, the surface of the filter mesh 1 66 can be backwashed, so that the solid particles attached to the filter mesh 1 66 can be in a relatively active state again, which is conducive to the smooth passage of the wine and can achieve flavor homogenization and exchange with the wine.

[0077] Furthermore, this embodiment also discloses another production and transportation system for fresh yellow wine. Figure 5 , Figure 6 , Figure 7 A detailed description is given to further design the flow guide pipe 4 and the filtering device 6.

[0078] Reference Figure 5 , Figure 6 , Figure 7 As shown, the outer periphery of the flow guide tube 4 is provided with an annular groove 81, the annular groove 81 surrounds the flow guide tube 4, and an elastic ring 8 is sleeved in the annular groove 81. The elastic ring 8 is an elastic rubber ring, and the inner periphery of the opening on one side of the filter screen 1 66 is connected to the outer periphery of the elastic ring 8, and the filter screen 1 66 is sleeved and connected to the outer periphery of the flow guide tube 4 through the elastic ring 8. That is, the elastic ring 8 itself is elastically embedded in the annular groove 81, so that the elastic ring 8 and the filter screen 1 66 can be elastically restricted in the area of ​​the annular groove 81, and the filter screen 1 66 is kept in a roughly limited state.

[0079] The elastic ring 8 can be elastically deformed relative to the outer periphery of the flow guide tube 4. When the elastic ring 8 is deformed, the filter screen 66 can adaptively follow the elastic ring 8 to be elastically deformed.

[0080] A plurality of movable blocks 82 are fixedly connected to the inner periphery of the elastic ring 8. A slot 83 is provided on the inner side of the guide tube 4 corresponding to the ring groove 81. The slot 83 penetrates the inner cavity of the guide tube 4. The movable blocks 82 and the slot 83 are adapted to each other. The movable blocks 82 can slide and adjust in the slot 83. When the movable blocks 82 slide toward the outer periphery of the guide tube 4, part of the inner periphery of the elastic ring 8 is separated from the guide tube 4, forming a gap 85 connected to the filtering space. Figure 7 Status shown.

[0081] Moreover, since the filling barrel is usually installed in an inverted structure when in use, the gap 85 formed by the inner circumference of the elastic ring 8 is open and facing downward. The filtering space in the filter screen 66 is in a downwardly open state, and the solid particles in the filtering space inside the filter screen 66 can enter the outside of the filter screen 66 from the gap 85, and then the solid particles can be dispersed in the entire wine storage space, so that the solid particles can fully contact with the liquid as much as possible.

[0082] Specifically, a guiding inclined surface 84 is formed at one end of the movable block 82 facing the inner cavity of the guide tube 4. The guiding inclined surface 84 and the end of the slide groove are adapted to each other, and the guiding function is achieved through the inclined surface and chamfer to maintain the smooth movement of the movable block 82. When the sliding sleeve 61 is completely retracted into the guide tube 4, the sliding sleeve 61 and the movable block 82 are against each other, pushing the movable block 82 to move toward the outer circumference of the guide tube 4. When the sliding sleeve 61 partially extends outside the guide tube 4, the sliding sleeve 61 and the movable block 82 are misaligned, the elastic ring 8 will be reset, and the movable block 82 will retract toward the inner circumference of the guide tube 4.

[0083] When the movable block 82 slides toward the inner circumference of the flow guide tube 4, the elastic ring 8 is embedded in the slide groove, and the gap 85 between the elastic ring 8 and the flow guide tube 4 is closed. At this time, the filling barrel is in the wine discharging state, and the wine is filtered twice by the filter screen 1 66 and the filter screen 2 69 to ensure that the output wine is in a relatively clear state.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
