Description

Technical Field

[0001] The invention relates to the technical field of wine production, in particular to a process for preparing dry white wine. Background Art

[0002] Dry white wine is a kind of wine with refreshing taste, moderate acidity and almost no sugar. The current dry white wine brewing process mainly includes grape picking and sorting, flexible pressing juice extraction, low-temperature clarification, temperature-controlled alcohol fermentation, malolactic fermentation and bottling operations, among which the most important are malolactic fermentation and bottling operations.

[0003] At present, these two main processes have the following defects: 1. Traditional malolactic fermentation is generally carried out in stainless steel tanks or oak barrels, and the brewed wine has less aroma and poor taste fullness. At the same time, traditional dry white wine brewing generally adopts malolactic complete fermentation. The malic acid conversion is too thorough, the wine body has no skeleton, and it is soft and weak, making the brewed taste not soft and refreshing enough; 2. The current filling operation process adopts the method of directly plugging the cork into the bottle mouth at one time during the capping stage. This method will produce greater stress at the bottle mouth, especially for thin-walled glass bottles, which can easily cause the bottle mouth to break or crack. During the direct insertion process, the cork will also be subjected to greater pressure and friction, and the cork may be damaged, cracked or deformed. In addition, the air in the bottle cannot be discharged in time, resulting in uneven residual gas in the bottle, affecting the long-term preservation of the wine.

[0004] In addition, during filling, the existing process of cleaning the wine bottles is only to insert a cleaning tube into the wine bottles and rinse them with water pressure. The cleaning method is relatively simple, and it is difficult to clean the inner wall of the bottle and the dead corners of the bottom of the bottle, resulting in incomplete cleaning. Summary of the invention

[0005] The invention provides a dry white wine preparation process, which solves the problem that traditional malolactic fermentation is carried out in stainless steel tanks or oak barrels, which usually results in insufficient wine aroma and a soft taste. In addition, the traditional plugging method directly plugs the cork into the bottle mouth at one time, which is easy to cause stress damage to the thin-walled glass bottle, and the cork is easily damaged during the plugging process, and the gas in the bottle cannot be discharged evenly, affecting long-term storage. At the same time, the existing cleaning process only relies on water pressure flushing, and it is difficult to thoroughly clean the dead corners of the inner wall and the bottom of the wine bottle.

[0006] The present invention provides a dry white wine preparation process, and the specific dry white wine preparation process steps are as follows:

[0007] S1. Grape picking and sorting: Grapes needed for winemaking are picked quickly during the cool early morning hours, and unevenly mature bunches and diseased fruits are sorted and removed during the picking process.

[0008] S2. Flexible squeezing and juice extraction: The grapes picked and sorted are subjected to flexible squeezing and juice extraction by using an airbag press. An appropriate amount of sulfur dioxide is added to the grape juice receiving hopper, and dry ice protective gas is intermittently added to obtain grape juice.

[0009] S3. Low temperature clarification: After the grape juice is extracted, the sulfur dioxide content in the grape juice is supplemented, and an appropriate amount of pectinase is added to the grape juice and the temperature of the grape juice is quickly reduced to a low temperature suitable temperature to remove the suspended solids in the grape juice to obtain clear grape juice.

[0010] S4. Temperature-controlled alcohol fermentation: Add an appropriate amount of white wine brewing yeast to the grape juice for alcohol fermentation. The temperature of the alcohol fermentation process is controlled at an appropriate temperature and the grape juice specific gravity and temperature are monitored three times a day to ensure normal fermentation. When the sugar content of the grape juice drops to an appropriate value, the alcohol fermentation ends and the clear juice is separated to obtain the wine.

[0011] S5. Malolactic semi-fermentation in ceramic jars: Pour the wine into ceramic jars for malolactic semi-fermentation. Add an appropriate amount of medium-baked French oak boards into the ceramic jars, control the fermentation temperature and ambient humidity, and use nitrogen to circulate and stir the wine once a week during the fermentation process. At the same time, monitor the malic acid content in the wine during the fermentation process. When the malic acid content drops to an appropriate level, quickly pour the wine into a stainless steel tank, adjust the sulfur dioxide content in the wine and lower the temperature to an appropriate level, terminate the malolactic semi-fermentation operation, add appropriate bentonite to the stainless steel wine for gum treatment, and clarify and sterilize and filter after standing for a certain period of time to obtain the desired dry white wine.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0042] See also Figure 1 , Figure 2 and Figure 3 The present invention provides a technical solution: a process for preparing dry white wine, and the specific steps of the process for preparing dry white wine are as follows:

[0043] S1. Grape picking and sorting: Grapes needed for winemaking are picked quickly during the cool early morning hours, and unevenly mature bunches and diseased fruits are sorted and removed during the picking process.

[0044] S2. Flexible squeezing and juice extraction: The grapes that have been picked and sorted are subjected to flexible squeezing and juice extraction by an air bag press. The air bag press is an existing professional equipment used to extract grape juice from grapes during the winemaking process. This equipment uses air bags to gently squeeze the grapes to minimize the impact of solid matter such as grape skins and seeds on the grape juice, thereby obtaining high-quality grape juice. An appropriate amount of sulfur dioxide is added to the grape juice receiving hopper, and dry ice protective gas is intermittently added to obtain grape juice.

[0045] S3. Low temperature clarification: After the grape juice is extracted, the sulfur dioxide content in the grape juice is supplemented, and an appropriate amount of pectinase is added to the grape juice and the temperature of the grape juice is quickly reduced to a low temperature suitable temperature to remove the suspended solids in the grape juice to obtain clear grape juice.

[0046] S4. Temperature-controlled alcohol fermentation: Add an appropriate amount of white wine brewing yeast to the grape juice for alcohol fermentation. The temperature of the alcohol fermentation process is controlled at an appropriate temperature and the grape juice specific gravity and temperature are monitored three times a day to ensure normal fermentation. When the sugar content of the grape juice drops to an appropriate value, the alcohol fermentation ends and the clear juice is separated to obtain the wine.

[0047] S5. Malolactic semi-fermentation in ceramic jars: Pour the wine into ceramic jars for malolactic semi-fermentation. Add an appropriate amount of medium-baked French oak boards into the ceramic jars, control the fermentation temperature and ambient humidity, circulate and stir the wine with nitrogen once a week during the fermentation process, monitor the malic acid content in the wine during the fermentation process, quickly pour the wine into a stainless steel tank when the malic acid content drops to an appropriate level, adjust the sulfur dioxide content in the wine and lower the temperature to an appropriate level, terminate the malolactic semi-fermentation, add appropriate bentonite to the stainless steel wine for gelling treatment, let it stand for a certain period of time, clarify and sterilize and filter to obtain the desired dry white wine. Adding French oak boards can increase the caramel and toffee aroma of the wine, while circulating and stirring the wine can allow the wine to fully contact with the oak boards and the high-quality sludge at the bottom, thereby increasing the fullness of the taste and the complexity of the aroma of the original wine.

[0048] S6, filling operation: the obtained dry white wine is filled by the filling mechanism 2 to obtain bottled dry white wine.

[0049] The dry white wine preparation process steps in the above steps S1-S6 need to be completed by the workbench 1 and the filling mechanism 2 in cooperation.

[0050] A filling mechanism 2 is installed on the upper end surface of the workbench 1, and the filling mechanism 2 includes a centrifugal cleaning part 21 arranged on the left part of the upper end surface of the workbench 1 for cleaning the inner cavity of the wine bottle, a filling part 22 arranged on the middle part of the upper end surface of the workbench 1, a conveying part 23 arranged on the upper part of the workbench 1 for driving the wine bottle to move, a combined stopper cover part 24 arranged on the right part of the upper end surface of the workbench 1 for accurately plugging the cork into the mouth of the wine bottle and filling the wine bottle with inert gas, and a linkage part 25 arranged on the rear part of the upper end surface of the workbench 1 for linking the combined stopper cover part 24 with the centrifugal cleaning part 21. The vertical moving part and the filling part 22 are both existing wine bottle conveying equipment and filling equipment, and the conveying part 23 has a flipping function.

[0051] See also Figure 2 and Fig.11 In this embodiment, the centrifugal cleaning part 21 includes a support 211 fixedly connected to the upper end surface of the workbench 1, a sliding frame 212 is fixedly connected to the upper end surface of the support 211, a sliding seat 213 is slidably connected in the sliding frame 212, an L-shaped tube 214 is embedded and fixedly connected in the sliding seat 213, a rotating tube 215 is rotatably connected to the upper end of the L-shaped tube 214, a plurality of flexible brush strips 216 are fixedly connected to the outer wall of the rotating tube 215 along its own axial and circumferential directions, and a plurality of water spray holes 217 are opened on the outer wall of the rotating tube 215 along its own circumferential and axial directions at equal intervals.

[0052] When filling dry white wine, the empty wine bottles are first stacked on the conveying part 23 in sequence, and the conveying part 23 drives the wine bottles to move to the right and pass through the centrifugal cleaning part 21 for cleaning. When passing through the centrifugal cleaning part 21, the wine bottles are in an inverted state, and then the wine bottles are driven to turn over and straighten and enter the filling part 22, and the dry white wine is injected into the wine bottles through the filling part 22. Then the conveying part 23 drives the wine bottles filled with dry white wine to move to just below the combined stopper cover part 24, and then the combined stopper cover part 24 is controlled to insert the cork into the bottle mouth. The combined stopper cover part 24 and the centrifugal cleaning part 21 work synchronously, that is, when the combined stopper cover part 24 is running to stopper the wine bottle, it will drive the centrifugal cleaning part 21 to move upward and enter the wine bottle through the linkage part 25.

[0053] When the centrifugal cleaning part 21 is in operation, it will first be driven upward by the linkage part 25 and extend into the inverted empty wine bottle: then water is introduced into the L-shaped tube 214, and the water flows into the rotating tube 215 through the L-shaped tube 214, and then the rotating tube 215 is driven to rotate by an external driving device. During the rotation of the rotating tube 215, the flexible brush strip 216 is driven to rotate synchronously. Under the action of the centrifugal force generated during the rotation, the flexible brush strip 216 will change from the initial naturally hanging state to the state after being unfolded to the outside. The unfolded flexible brush strip 216 contacts the inner wall of the wine bottle and rotates. The flexible brush strip 216 is used to adaptively extend according to the shape of different parts of the inner wall of the wine bottle, so that the inner wall and the bottom of the wine bottle can be fully cleaned, and the water column injected into the rotating tube 215 and sprayed out from the water spray hole 217 to flush the inner wall of the wine bottle, so that the inner wall of the wine bottle can be cleaned in different ways. The two cleaning methods are superimposed on each other to greatly improve the cleaning effect.

[0054] See also Figure 4 , Figure 5 , Figure 6 and Figure 7In this embodiment, the combined plug cover part 24 includes an L-shaped mounting frame 241 fixedly connected to the upper end surface of the workbench 1, a No. 1 electric telescopic rod 242 fixedly connected to the front end surface of the vertical section of the L-shaped mounting frame 241 through a fixing block, a docking tube 243 fixedly connected to the lower end of the No. 1 electric telescopic rod 242 through a connecting block, a positioning ring 244 fixedly connected to the lower part of the docking tube 243 through a connecting rod, an annular plug 245 slidably connected in the docking tube 243, a columnar plug 246 arranged in the annular plug 245, a component 247 arranged between the docking tube 243 and the columnar plug 246 for stacking the wooden plugs and moving them intermittently so that the wooden plugs drive the intermediate shifting material component 247 in the docking tube 243, and a component 247 arranged between the annular plug 245 and the columnar plug 246 for clamping the two. A connecting and separating card assembly 248, an inlet pipe 2410 connected to the outside of the docking tube 243 for introducing inert gas, and a through-and-closing assembly 249 jointly arranged between the columnar plug 246 and the inlet pipe 2410 for controlling the intermittent introduction of inert gas into the docking tube 243, the columnar plug 246 is used to cooperate with the intermediate code material assembly 247 to facilitate the initial pushing of the wooden cork downward to dock with the wine bottle mouth, an L-shaped plate is fixedly connected to the upper end face of the docking tube 243, and a No. 2 electric telescopic rod 2411 is fixedly connected between the transverse section of the L-shaped plate and the annular plug 245 to drive the annular plug 245 to move downward and further push the wooden cork so that the wooden cork can be completely inserted into the wine bottle mouth, and an annular groove 5 is opened at the lower end of the docking tube 243, and an elastic annular sealing gasket 6 is fixedly connected to the groove wall of the annular groove 5.

[0055] See also Figure 6 , Figure 7 and Figure 8 The card-off assembly 248 includes two mounting grooves 2481 symmetrically arranged in the columnar plug 246. The groove walls on the opposite sides of the two mounting grooves 2481 are slidably connected to the vertical slide 2483 through the spring telescopic column 2482. The lower parts of the opposite sides of the two vertical slides 2483 are fixedly connected to the card blocks 2484. The card blocks 2484 are provided with a bayonet 2485 on the side away from the vertical slide 2483. The inner wall of the annular plug 245 is fixedly connected to the card head 2486 that cooperates with the bayonet 2485. The upper part of the card block 2484 is provided with a guide slope 2487. The transverse section of the L-shaped mounting frame 241 The lower end surface is fixedly connected to a special-shaped frame 2488 through a fixed column for cooperating with the vertical slide bar 2483 to control the separation of the block 2484 and the clamping head 2486. The special-shaped frame 2488 consists of an inverted U-shaped section and an inclined section fixedly connected to the lower part of the vertical section of the inverted U-shaped section. A guide groove 3 is axially provided on the outer wall of the cylindrical plug 246, and a guide block 4 arranged in the guide groove 3 is fixedly connected to the inner wall of the circumference of the annular plug 245. The guide block 4 cooperates with the guide groove 3 to limit the cylindrical plug 246, so that the cylindrical plug 246 can only move along its own axial direction when moving.

[0056] In the initial state, the clamping assembly 248 clamps the cylindrical plug 246 and the annular plug 245 together, and the external inert gas is introduced into the inlet pipe 2410. First, the wooden plugs are put into the intermediate code material assembly 247 in turn, and then the No. 1 electric telescopic rod 242 is controlled to extend to drive the docking tube 243 to move downward, and the docking tube 243 then drives the positioning ring 244 to move downward synchronously and be sleeved on the outside of the wine bottle directly below the docking tube 243. The positioning ring 244 moves downward and contacts the arc surface of the bottle shoulder on the outside of the wine bottle to align The wine bottle is automatically straightened and limited in position, at which time the docking sleeve 243 moves down to the annular groove 5 at its lower part and is sleeved on the outside of the bottle mouth, and the elastic annular sealing gasket 6 contacts the port of the wine bottle. Then the No. 1 electric telescopic rod 242 is controlled to stop extending, and then the No. 2 electric telescopic rod 2411 is controlled to contract to drive the annular plug 245 to move up, and the annular plug 245 then drives the columnar plug 246 to move up through the card-release assembly 248, thereby gradually extracting the air in the wine bottle, so that the space between the docking sleeve 243 and the wine bottle gradually becomes negative pressure.

[0057] During the upward movement of the cylindrical plug 246, the opening and closing component 249, the intermittent coding component 247 and the card-release component 248 will be triggered in sequence to operate. When the opening and closing component 249 is triggered, the inlet pipe 2410 and the docking tube 243 will be briefly connected, and the negative pressure in the docking tube 243 will be used to suck the inert gas from the inlet pipe 2410 into the docking tube 243, and then the inlet pipe 2410 and the docking pipe will become disconnected. When the intermittent coding component is triggered to operate, the wooden plug will be moved into the docking tube 243.

[0058] Then, when the card separation component 248 is in operation: the upwardly moving cylindrical plug 246 drives the vertical slide bar 2483 to hit the lower inclined surface of the inclined section in the special-shaped frame 2488, and then the inclined surface of the inclined section in the special-shaped frame 2488 squeezes the vertical slide bar 2483, so that the two vertical slide bars 2483 move closer to each other, and the vertical slide bar 2483 then drives the block 2484 to move closer to the axis of the cylindrical plug 246, and the block 2484 drives the bayonet 2485 to gradually move away from the clamping head 2486, until the bayonet 2485 and the clamping head 2486 are completely separated, and then the cylindrical plug 246 will be sucked and moved downward quickly under the action of the negative pressure in the docking tube 243, and the cylindrical plug 246 The downward movement pushes the wooden cork in the docking tube 243 downward, so that the wooden cork initially moves downward and hits the mouth of the wine bottle, and then the No. 2 electric telescopic rod 2411 is controlled to extend to drive the annular plug 245 downward. When the annular plug 245 moves downward to the position where its lower part hits the block 2484, the annular plug 245 and the guide slope 2487 squeeze each other so that the two blocks 2484 move closer to each other until the annular plug 245 is sleeved on the outside of the block 2484, thereby driving the clamping head 2486 to be clamped into the middle clamping mouth 2485 again, and then, the annular plug 245 drives the columnar plug 246 to move downward and push the wooden cork to move, so that the wooden cork moves downward for a second time until the wooden cork is completely inserted into the wine bottle.

[0059] By inserting the cork in two times, pressure can be applied gradually to avoid excessive stress on the bottle mouth when the cork is inserted all at once, effectively reducing the risk of thin-walled glass bottles breaking or cracking during the corking process, and reducing the situation where the cork is subjected to excessive force, thereby reducing the friction and compression stress of the cork, avoiding the cork from breaking, cracking or deforming during the insertion process. The air in the bottle can also be extracted before corking, which can better ensure that the cork fits tightly against the bottle mouth.

[0060] After the cork is completely inserted into the middle of the wine bottle, the No. 1 electric telescopic rod 242 is controlled to contract to drive the docking tube 243 to move upward, and the docking tube 243 then drives the positioning ring 244 to move upward and separate from the wine bottle, so that the docking tube 243 moves to the initial position, and then the above steps are repeated again to perform the capping operation on the next wine bottle.

[0061] See also Figure 2 and Figure 3In this embodiment, the linkage part 25 includes a support 251 fixedly connected to the upper end surface of the workbench 1 and a two-way telescopic rod 252 hinged on the upper part of the support 251. A No. 1 connecting column 253 is hinged between the left part of the two-way telescopic rod 252 and the slide 213, and a No. 2 connecting column 254 is hinged between the right part of the two-way telescopic rod 252 and the docking tube 243. When the No. 1 electric telescopic rod 242 is extended to drive the docking tube 243 to move downward, the docking tube 243 then drives the two-way telescopic rod 252 to rotate clockwise through the No. 2 telescopic column, and then the two-way telescopic rod 252 is retracted. The rod 252 then drives the slide 213 to move upward through the No. 1 connecting column 253, and the slide 213 then drives the rotating tube 215 to move upward, so that the rotating tube 215 extends into the wine bottle, so that the empty wine bottle can be cleaned while the plug is closed. When the plug is closed, the docking tube 243 drives the two-way telescopic rod 252 to rotate counterclockwise through the No. 2 connecting column 254, and the two-way telescopic rod 252 then drives the slide 213 to move downward through the No. 1 connecting column 253, and the slide 213 then drives the rotating tube 215 to move downward and be drawn out of the wine bottle.

The right end face of the folding rod 2494 is fixedly connected to a limiting spring together with the shift column 2495 through a protrusion.

[0063] During the upward movement of the columnar plug 246, the folding rod 2494 is driven to move synchronously, and the folding rod 2494 then drives the lever 2495 to move upward. When the lever 2495 moves upward, it will contact the L-shaped lever 2493. The upward movement of the lever 2495 drives the L-shaped lever 2493 to move upward synchronously. The L-shaped lever 2493 then drives the valve plate 2492 to move upward, so that the left and right sections of the inlet pipe 2410 are connected, and then the inert gas can enter. In the docking tube 243, the cylindrical plug 246 that continues to move upward drives the lever 2495 to rotate around the rotating column, and the limit spring is stretched. When the cylindrical plug 246 moves downward, the folding rod 2494 is driven to move downward synchronously, and the folding rod 2494 then drives the lever 2495 to move downward and abut against the L-shaped lever strip 2493, and then the lever 2495 starts to rotate around the rotating column until the lever 2495 passes over the L-shaped lever strip 2493.
