Description

Technical Field

[0001] This utility model relates to a decanting device, and more particularly to a multifunctional decanting device. Background Technology

[0002] Traditional decanters typically use an open container structure, relying on natural settling or manual shaking to promote contact between the wine and air. These devices have functional limitations: they cannot actively separate sediment or impurities from the wine, nor can they control the decanting process. They also have significant shortcomings in wine preservation—once opened, they cannot isolate the wine from oxygen, leading to rapid flavor deterioration, and they lack temperature control capabilities. While existing technologies attempt to introduce single additional functions (such as simple filtration or vacuum suction), these functional modules are fragmented and cannot synergistically address the comprehensive needs of decanting, preservation, sediment management, and temperature control.

[0027] Figure 2 This is a schematic diagram of a multifunctional hangover decanting device according to another embodiment of the present invention. Detailed Implementation

[0028] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0029] Example 1

[0030] This utility model provides a multifunctional hangover decanting device; see details below. Figure 1 It includes: a tank body 101, a gas control assembly, a flow guiding assembly, and a refrigeration assembly; the bottom of the tank body 101 is provided with a sediment discharge port 102 and a pouring port 103, with the pouring port 103 located directly above the sediment discharge port 102; the gas control assembly includes an air pump 201, a nitrogen generator 203, and a vacuum pump 205; the air pump 201 is connected to the first air inlet of the tank body 101 through a first pipeline 202; the nitrogen generator 203 is connected to the tank body 101 through a second pipeline 204. The second air inlet is connected; the vacuum pump 205 is connected to the air extraction port of the tank 101 through the third pipeline 206; the flow guiding assembly includes a flow guiding inclined plate 301, which is fixed to the inner wall of the tank, and the lower edge of the flow guiding inclined plate 301 points to the sediment discharge port 102; the flow guiding inclined plate 301 and the side wall of the tank form a sedimentation chamber 302, and the side wall of the sedimentation chamber is embedded with a transparent observation window; the cooling assembly includes a semiconductor cooling chip 401; the cold end of the semiconductor cooling chip 401 is attached to the bottom surface of the tank.

[0031] This utility model provides a multifunctional wine aeration device, the core structure of which is composed of four major components: a tank component providing space for the wine and functional interfaces, a gas control component managing the gas for aeration and preservation, a flow guiding component dedicated to separating and guiding sediment, and a refrigeration component responsible for precise temperature control of the wine. These components are physically connected to form an integrated device, which is described in detail below with reference to the accompanying drawings.

[0032] I. Detailed Description of Tank Component Structure

[0033] The tank body 101 is made of food-grade stainless steel. A sediment discharge port 102 is located at the center of the bottom, preferably a flanged stopcock valve (not labeled in the figure). A pouring spout 103 is positioned directly above the discharge port 102, with their central axes coinciding and a vertical distance of 10-15 mm between them. This arrangement ensures physical isolation between the liquid flow path and the sediment discharge path during pouring. Specifically, when the tank is tilted for pouring, the liquid flows naturally from the pouring spout 103, while the sediment, under gravity, slides along the guide path into the area below the discharge port 102, avoiding cross-contamination.

[0034] II. Working Mechanism of the Airflow Guiding Component

[0035] The guide plate 301 is fixed to the inner wall of the tank by laser welding, with an inclination angle preferably between 55 and 65 degrees. This guide plate and the tank side wall together form a V-shaped settling chamber 302, the bottom of which is directly connected to the discharge port 102. The key design features are:

[0036] The lower edge of the guide plate 301 is precisely controlled to be 5-8mm from the center of the discharge port, forming an unobstructed sliding channel.

[0037] The inclined plate surface is covered with a PTFE coating 305 (thickness 0.20±0.05mm), which utilizes the ultra-low coefficient of friction of polytetrafluoroethylene to ensure zero residue of precipitates;

[0038] The edge of the inclined plate is machined with a U-shaped guide groove of 306. The curvature of the groove matches the outer diameter of the discharge port flange, with a gap of ≤0.5mm.

[0039] Exemplary application: When the wine contains tartaric acid crystals, the crystals slide along the PTFE coating surface into the guide channel 306, and are guided directly into the discharge port 102. The tempered glass observation window (not labeled in the figure) embedded in the side wall of the sedimentation chamber 302 can monitor the amount of sediment in real time.

[0040] III. Implementation Methods of Gas Control Components

[0041] The gas control unit comprises three independent gas path systems, all connected via rigid piping:

[0042] 1. Decanting air circuit system: air pump 201 → first pipeline 202 → microporous diffuser at the bottom of the can;

[0043] The microporous diffuser 210 is preferably a sintered titanium alloy body with a three-zone structure of 10 micrometers / 30 micrometers / 50 micrometers in terms of pore size.

[0044] Gas is injected from the bottom of the tank, forming a cluster of microbubbles to increase the gas-liquid contact area;

[0045] 2. Freshness preservation gas system: Nitrogen generator 203 → Second pipeline 204 → Second air inlet 205 on top of tank;

[0046] Nitrogen gas is injected from the top of the tank to form an inert gas protective layer;

[0047] 3. Vacuum system: Vacuum pump 206 → Third pipeline 207 → Tank top evacuation port 208;

[0048] A stainless steel filter screen is embedded in the air extraction port to prevent liquid from being drawn in.

[0049] Example of collaborative operation: During the decanting stage, air pump 201 is activated to inject air; during the preservation stage, nitrogen injection is switched and then the vacuum pump is activated.

[0050] IV. Technical Details of Refrigeration Components

[0051] The TEC 401 thermoelectric cooler achieves efficient temperature control through the following structure:

[0052] The cold end is bonded to the bottom surface of the tank via a copper-doped thermally conductive silicone layer 402 (copper powder content 15-20wt%), with a contact area ≥90%.

[0053] The hot end is connected to a microgrooved aluminum heat sink 502, with a groove depth of 0.5mm and a spacing of 2mm;

[0054] The overall refrigeration capacity covers the range of tank volume (typically applicable to 0.5-2L of wine).

[0055] Temperature maintenance example: When the serving temperature is set to 16℃, the TEC module automatically adjusts the current direction and intensity, and the temperature fluctuation at the bottom of the can is ≤±0.5℃.

[0056] Optionally, the surface of the guide plate 301 is covered with a PTFE coating 305; the edge of the guide plate 301 is provided with a guide groove 306, which is connected to the sediment discharge port 102.

[0057] Optionally, the angle of the guide vane 301 is any angle between 10 degrees and 60 degrees; and / or, the thickness of the PTFE coating 305 is greater than or equal to 0.2 mm.

[0058] In this invention, the guide plate 301 serves as the core component of the sedimentation management system, and its special surface treatment and edge structure have a decisive influence on the sediment separation efficiency. The following is a systematic description of the technical details of the PTFE coating 305 and the guide channel 306:

[0059] I. Functional Principles and Technical Details of PTFE Coating

[0060] Functional Positioning: The PTFE (polytetrafluoroethylene) coating endows the surface of the flow guide plate with permanent non-adhesive properties, solving the problem of sediment adhesion from a physicochemical perspective. Its core value lies in:

[0061] Ultra-low surface energy (≤18mN / m): below the critical value for adhesion of tartaric acid crystals (>30mN / m), making it impossible for precipitates to adhere;

[0062] Chemical inertness: Resistant to strong acid and alkali environments with pH 1-14, and resistant to corrosion by organic acids in wine;

[0063] Temperature stability: Maintains stable performance within the range of -50℃ to 250℃, covering refrigeration and sterilization conditions.

[0064] Application example: When tartaric acid crystals (0.1-0.5mm in size) in aged red wine come into contact with the coating surface, they cannot establish an effective adhesion interface and slide off under the influence of gravity.

[0065] II. Structural Coordination and Spatial Relationship of the Guide Channel

[0066] Functional positioning: The guide channel 306 is a directional conveying channel connecting the inclined plate and the discharge port, and its structural design must meet the following requirements:

[0067] Eliminate dead zones where sediment can accumulate at the edges of the inclined plate;

[0068] Establish an unobstructed transition path to the emission outlet.

[0069] Example of collaborative work:

[0070] After the precipitate slides along the PTFE coating surface to the guide channel 306:

[0071] 1. The flow is directional due to the constraint of the sidewalls of the tank;

[0072] 2. The direction of motion is changed by the arc-shaped guide surface;

[0073] 3. It accurately lands in the central area of ​​the emission outlet 102.

[0074] The entire process requires no external intervention, achieving gravity-driven discharge.

[0075] Optionally, the gas control assembly also includes an exhaust valve 207, which is connected to the outlet of the tank 101 via a fourth pipe 208.

[0076] In the gas control assembly of this utility model, the exhaust valve 207 and its connecting structure are key modules for achieving degassing and preservation of the wine. The following is a systematic explanation from three aspects: functional positioning, structural coordination, and working logic.

[0077] I. Core Functions and System Positioning of the Exhaust Valve

[0078] Technical necessity:

[0079] During the transition from decanting to preservation, it is necessary to expel harmful gases (such as hydrogen sulfide, sulfur dioxide, and other reducing substances) from the container while preventing contamination from external air backflow. The core functions of the exhaust valve 207 include:

[0080] 1. Directional exhaust: Actively exhausting sulfide-containing gases during the nitrogen replacement stage;

[0081] 2. Pressure balance: Balance the pressure difference inside and outside the tank before vacuum pumping;

[0082] 3. Backflow prevention isolation: Prevents external gas from flowing back in.

[0083] System integration relationships:

[0084] Position logic: Connect to the highest point of the tank top (gas outlet) via the fourth pipe 208 to ensure priority exhaust from the gas accumulation area;

[0085] Synergistic component: It forms a "nitrogen filling-exhausting" cycle with nitrogen generator 203 and works with vacuum pump 205 to establish negative pressure.

[0086] II. Implementation Details of the Exhaust Valve Structure

[0087] Preferred mechanical structure scheme:

[0088] The exhaust valve 207 is preferably a plug-type ceramic valve, whose core features are:

[0089] 1. Valve core flow guiding structure:

[0090] The valve core (not shown in the figure) has a spiral air guide groove with a groove depth of 0.5-0.8mm;

[0091] The plug taper is 1:6 to ensure that the contact pressure of the sealing surface is >0.3 MPa;

[0092] 2. Anti-clogging design:

[0093] A stainless steel filter screen (0.3±0.05mm aperture) is embedded in the valve seat inlet to intercept wine foam;

[0094] The valve stem seal uses a double O-ring fluororubber ring (temperature resistant -20℃~150℃);

[0095] 3. Connection method:

[0096] The fourth pipeline 208 is connected to the valve body by a compression fitting thread (M10×1 thread).

[0097] A diffuser is installed at the air outlet to reduce exhaust noise (<65dB);

[0098] Exemplary application scenario: When nitrogen generator 203 fills the tank with nitrogen, the density of the sulfide-containing gas accumulating at the top of the tank increases. At this time, the exhaust valve 207 is opened, and the gas forms a swirling flow along the spiral gas guide groove to accelerate its discharge. After the gas is completely discharged, the valve is closed and the vacuum pump 205 is immediately started.

[0099] III. Dynamic Collaboration Logic with Gas Components

[0100] Work phase sequence description:

[0101] 1. Nitrogen purging and exhaust stage:

[0102] Nitrogen generator 203 is working → A high-concentration nitrogen layer is formed on the top of the tank;

[0103] Exhaust valve 207 opens → Sulfide gas is discharged after being filtered through the filter screen;

[0104] The gas color changes (yellow-green → colorless) can be observed through the observation window (unlabeled);

[0105] 2. Vacuum establishment stage:

[0106] Exhaust valve 207 remains closed → forming a closed system;

[0107] Vacuum pump 205 starts → The pressure inside the tank drops below 10 kPa;

[0108] 3. Security protection mechanism:

[0109] When the pressure inside the tank is greater than 0.15 MPa, the gas pushes open the valve core to achieve automatic pressure relief;

[0110] After pressure relief, the valve core self-realigns (reset time < 0.5 seconds).

[0111] Optionally, the multi-functional decanter also includes a control device 100; the control device 100 is electrically connected to an air pump 201, a nitrogen generator 203, a vacuum pump 205, and an exhaust valve 207.

[0112] In this invention, the control device 100 is an optional module that enables efficient operation of the gas control component and the refrigeration component through electrical coordinated management. It should be noted that the implementation of this module requires the aforementioned mechanical structure and represents an intelligent extension of the system's functionality.

[0113] I. Core Positioning and Technical Value of the Control Device

[0114] Functional positioning:

[0115] The control device 100 acts as a central coordinating unit, linking various actuators via electrical signals to achieve:

[0116] 1. Timing logic control: Coordinates the start-up and shutdown sequence of the gas pump, nitrogen generator, vacuum pump, and exhaust valve;

[0117] 2. Dynamic parameter adjustment: Optimize operating parameters based on sensor feedback;

[0118] 3. Safety monitoring: Protection against abnormal conditions such as overpressure and overtemperature;

[0119] System integration relationships:

[0120] Hardware infrastructure: such as air pump 201 and exhaust valve 207 are the physical carriers;

[0121] Signal interaction: The electrical interfaces of each actuator (such as motor drive end, valve coil) are connected via cables.

[0122] II. Physical Structure and Interface Specifications of the Control Device

[0123] Preferred implementation scheme:

[0124] The control device 100 adopts a modular design and includes:

[0125] 1. Main control unit:

[0126] Microprocessors (such as the ARM Cortex-M4 core);

[0127] The storage chip records wine optimization parameters (such as Cabernet Sauvignon decanting mode);

[0128] 2. Drive circuit:

[0129] Air pump 201 is equipped with a PWM speed control circuit (frequency 10-20kHz).

[0130] The exhaust valve 207 is equipped with a relay drive circuit (response time < 10ms).

[0131] 3. Interface Standards:

[0132] The air pump / vacuum pump uses a 4-pin aviation connector (power supply + control dual channel).

[0133] The nitrogen generator uses an RS485 communication interface;

[0134] Exemplary connection: When the microprocessor receives the "decant start" command, it adjusts the speed of the air pump 201 to 2500 rpm through the PWM circuit, and at the same time opens the exhaust valve 207 to a half-open state (50% opening).

[0135] III. Dynamic Collaboration Logic with Gas Control Components

[0136] Typical workflow description:

[0137] 1. Sobering up stage:

[0138] Control device 100 starts air pump 201 (power gradient increase: 30%→100% / 2min);

[0139] Synchronously control the opening of the exhaust valve 207 (linearly closing from 100% to 20% as the wine decant time increases);

[0140] 2. Preservation and Transition Stage:

[0141] Turn off air pump 201 → Turn on nitrogen generator 203 (flow rate 200mL / min).

[0142] When the oxygen sensor reading is <1%, close the exhaust valve 207 and start the vacuum pump 205;

[0143] 3. Exception handling mechanism:

[0144] When the pressure sensor reading is >0.25MPa:

[0145] → Immediately shut off nitrogen generator 203;

[0146] → Fully open exhaust valve 207 to release pressure.

[0147] Alternatively, see details. Figure 2 A microporous diffuser 210 is provided at the bottom of the tank; the first air inlet is connected to the microporous diffuser 210 through the fifth pipe 209, which is used to diffuse the gas from the air pump 201 into the wine.

[0148] In this invention, the microporous diffuser 210 serves as the core actuator of the gas control system, and its structural features directly determine the decanting efficiency and gas utilization rate. The following explanation focuses on three dimensions: functional positioning, structural implementation, and system coordination.

[0149] I. Functional Positioning and Technological Value

[0150] Core function:

[0151] The microporous diffuser 210 performs the dual functions of gas dispersion and mass transfer enhancement:

[0152] 1. Bubble miniaturization: The macroscopic airflow delivered by the air pump 201 is broken into micron-sized bubbles (10-100 microns in diameter).

[0153] 2. Optimized gas-liquid contact: Increases the total surface area of ​​bubbles (5-8 times higher than ordinary aerators);

[0154] 3. Flow field guidance: A uniform rising bubble group is formed at the bottom of the tank to avoid local turbulent disturbance and sedimentation;

[0155] System positioning:

[0156] Position logic: It must be embedded in the bottom inner wall of tank 101, located on the back side of guide plate 301 (avoiding the sedimentation path).

[0157] Gas path connection: A closed gas path is formed with the first air inlet through the fifth pipe 209.

[0158] II. Structural Implementation Details

[0159] Preferred implementation scheme:

[0160] 1. Matrix material:

[0161] Food-grade titanium alloy (Gr.2) or zirconia ceramic, resistant to tartaric acid corrosion;

[0162] The base thickness is 2.0±0.2mm to ensure structural strength;

[0163] 2. Microporous structure:

[0164] Aperture gradient distribution:

[0165] Central area: 10-micron micropores (accounting for 40% of the total area);

[0166] Transition zone: 30-micron micropores (accounting for 50%);

[0167] Edge region: 50-micron micropores (accounting for 10%);

[0168] Pore ​​density control: 300-500 pores / cm², pore spacing is 2-3 times the pore diameter;

[0169] 3. Anti-clogging design:

[0170] The surface is coated with a nano-hydrophobic coating (contact angle > 150 degrees) to prevent wine from seeping into and clogging the pores.

[0171] Built-in backflush channel (not shown in the figure) can be connected to high-pressure nitrogen for unblocking;

[0172] Operating Example: When air pump 201 outputs 0.2MPa compressed air, the airflow enters the diffuser cavity through the fifth pipe 209. The gas preferentially overflows from the 50-micron edge hole, forming large bubbles that break the liquid surface tension, and then releases a cluster of microbubbles from the 10-micron central hole. The overall bubble diameter distribution is 20-80 microns.

[0173] III. Coordination Mechanism with System Components

[0174] Spatial layout requirements:

[0175] 1. Relationship with the flow guiding components:

[0176] The distance between the diffuser projection area and the edge of the guide plate 301 is greater than 50 mm.

[0177] The installation height should be 10-15mm lower than the lower edge of the deflector;

[0178] 2. Thermal coupling with refrigeration components:

[0179] The diffuser substrate is thermally coupled to the cold end of the semiconductor cooling chip 401;

[0180] The rising bubbles enhance the convective heat transfer of the wine (increasing the heat transfer coefficient by 30%).

[0181] Dynamic working logic:

[0182] Decanting stage: Air pump 201 → Fifth pipeline 209 → Microporous diffuser 210 → Release microbubble clusters (dissolved oxygen increase rate 2-3 mg / L·min);

[0183] Shutdown phase: Turn off air pump 201 → Hydrophobic coating on diffuser surface blocks liquid → Maintain airtightness.

[0184] Optionally, the pores of the microporous diffuser 210 are covered with a filter screen.

[0185] The filter layer added to the surface of the microporous diffuser 210 in this utility model is a design to enhance anti-clogging for wine liquids with high suspended solids, and is an optimized extension of the core structure. The following is a systematic explanation from three aspects: functional positioning, structural integration, and synergistic anti-clogging.

[0186] I. Core Functions and Technological Value of Filters

[0187] Technical necessity:

[0188] In traditional microporous diffuser applications, colloidal particles in the wine (such as protein polymers and yeast residue) easily clog the micropores (<50 micrometers). The core value of adding a filter layer lies in:

[0189] 1. Pre-filtration protection: Intercepts suspended particles larger than 100 microns, reducing the risk of micropore clogging;

[0190] 2. Homogenization of the flow field: breaking up large bubbles into microbubble clusters improves gas-liquid mass transfer efficiency;

[0191] 3. Extended maintenance cycle: The removable filter reduces the frequency of diffuser body cleaning;

[0192] System location logic:

[0193] Functional synergy: Forms a two-stage filtration system with the microporous diffuser 210;

[0194] Level 1: The filter intercepts large particles of impurities;

[0195] Second stage: Microporous diffuser refines bubbles;

[0196] Space constraints: The filter screen must be installed close to the diffuser surface (gap ≤ 1mm).

[0197] II. Implementation Details of the Filter Structure

[0198] Preferred technical solution:

[0199] 1. Net material and parameters:

[0200] Substrate: 316L stainless steel woven mesh or polytetrafluoroethylene (PTFE) membrane;

[0201] Aperture: 80-120 micrometers (approximately 2-3 times the minimum aperture of a microporous diffuser);

[0202] Opening ratio: ≥70% (to ensure airflow rate);

[0203] 2. Installation and fixing method:

[0204] Snap-on type: The filter screen edge is equipped with an elastic retaining ring (interference allowance 0.1-0.3mm);

[0205] Magnetic type: The diffuser substrate is embedded with a neodymium iron boron magnetic ring (magnetic induction intensity 0.3T);

[0206] Threaded locking: M45×1 thread is machined on the outer ring of the diffuser;

[0207] 3. Anti-clogging mechanism:

[0208] The mesh surface is coated with a nano-hydrophobic coating (contact angle > 150 degrees).

[0209] Install a backflushing interface (e.g., a quick-release Luer connector);

[0210] Example application: When processing homemade wine containing lees residue, the 120-micron stainless steel filter can intercept 99% of particles >100 microns (actual data), requiring only monthly disassembly and cleaning, while the microporous diffuser body remains maintenance-free year-round.

[0211] III. Synergistic Working Mechanism with Microporous Diffusers

[0212] Dynamic filtering process:

[0213] 1. Primary airflow distribution: When the airflow from the pump passes through the filter screen, particles larger than the pore size are trapped on the windward side of the filter screen;

[0214] 2. Microbubble generation: The filtered clean airflow enters the diffuser micropores and breaks into bubbles of 20-80 micrometers;

[0215] 3. Self-cleaning trigger: When the filter pressure difference is >5kPa, the backwash mode is triggered (e.g., by introducing 0.6MPa nitrogen).

[0216] Spatial layout requirements:

[0217] Height matching: The filter screen and the lower edge of the guide plate 301 maintain a vertical distance of >30mm;

[0218] Synergistic thermal management: The filter does not cover the contact area between the diffuser and the cooling element.

[0219] Optionally, the pouring spout 103 has a built-in one-way valve.

[0220] Optionally, a mechanical pressure gauge 701 is embedded in the top of the tank 101 to display the air pressure inside the tank 101.

[0221] The one-way valve 103 for the pouring spout and the pressure gauge 701 on the top of the tank, as a preferred solution to improve safety and convenience of use, need to be combined with the core structure to achieve functional expansion. The technical details of the two structures are systematically described below:

[0222] I. Functional Positioning and Structural Implementation of the One-Way Valve for Pouring Wine

[0223] Technical necessity:

[0224] With the sediment discharge port 102 and the pouring port 103 arranged perpendicularly and coaxially, the core function of the one-way valve is:

[0225] 1. Anti-backflow isolation: Prevents wine from flowing back into the sedimentation chamber 302 when pouring;

[0226] 2. Sediment interception: traps discrete particles that detach from the guide plate 301 during the pouring process;

[0227] 3. Air isolation: Automatic sealing after pouring to slow down the oxidation of the wine;

[0228] Structural implementation plan:

[0229] 1. Preferred valve body form:

[0230] Duckbill type silicone valve: normally closed, opening pressure 0.5-1.0 kPa;

[0231] Umbrella-shaped stainless steel valve: spring preload 2-3N;

[0232] 2. Key parameters:

[0233] Valve seat tilt angle: 40 to 50 degrees (optimizes liquid guidance);

[0234] Valve plate thickness: 1.0±0.1mm silicone material (food grade platinum vulcanization);

[0235] 3. Installation and positioning:

[0236] The bottom of the valve body is 10±0.5mm lower than the flange face of the discharge port;

[0237] The valve seat is interference-fitted with the inner wall of the pouring spout 103 (interference amount 0.05-0.1mm);

[0238] Example of operation: When pouring wine, the pressure of the liquid opens the duckbill valve to form a flow channel (opening degree of about 8-10mm). After the wine has flowed out, the valve closes by its own weight. If the wine contains sediment particles with a diameter >0.3mm, they will be trapped in the conical collection groove of the valve seat.

[0239] II. Functional Integration and System Correlation of Mechanical Pressure Gauges

[0240] Technological value:

[0241] Pressure gauge 701 directly monitors the pressure status inside the tank, achieving:

[0242] 1. Vacuum degree visualization: Real-time display of negative pressure value (-95~-100kPa) during the preservation stage;

[0243] 2. Safety warning: The pressure relief device will activate in case of overpressure.

[0244] 3. Process guidance: Optimize the decanting time based on the pressure curve;

[0245] Structural implementation specifications:

[0246] 1. Phenotypic selection:

[0247] Bourdon tube pressure gauge (range -0.1~0.5MPa).

[0248] Earthquake-resistant design;

[0249] 2. Installation Requirements:

[0250] It is fixed to the highest point of the tank top via a threaded interface;

[0251] The angle between the dial axis and the horizontal plane is ≤5 degrees (to ensure reading accuracy).

[0252] 3. Protective design:

[0253] The thickness of the glass surface is ≥3mm (Mohs hardness level 7).

[0254] A copper damping valve is installed at the interface (response time 0.5-1 second).

[0255] III. Collaborative Working Mechanism with Core Components

[0256] The coordination logic of the one-way valve at the pouring spout:

[0257] 1. Relationship with the flow guiding component:

[0258] The valve body projection must completely cover the outlet of sedimentation chamber 302;

[0259] The volume of the valve seat sludge collection tank is ≥ 5% of the volume of the sedimentation chamber;

[0260] 2. Linked with gas control:

[0261] When pouring wine, the vent valve 207 automatically opens to balance the pressure difference between the inside and outside of the tank.

[0262] Before starting the vacuum pump, ensure the check valve is closed.

[0263] System integration of pressure gauges:

[0264] 1. Vacuum preservation stage:

[0265] The timer is triggered when the pressure gauge reading drops to -95 kPa.

[0266] An alarm will sound to prompt for vacuum replenishment when the pressure rises to -80 kPa.

[0267] 2. Sobering up stage:

[0268] The pressure of air pump 201 fluctuates within ±0.5 kPa during operation;

[0269] When the overpressure reaches 0.25 MPa, shut down the air pump and start the pressure relief function.
