Description

Technical Field

[0001] The present invention relates to the technical field of wine distiller, and in particular to a control method, system and device for a wine distiller. Background Art

[0002] The birth of a bottle of liquor generally goes through the following steps: material selection, koji making, fermentation, distillation, aging, blending, bottling, etc., among which a wine distiller is needed during the distillation process.

[0003] A wine distiller is an apparatus for making or purifying wine by distillation. Its working principle is to use the characteristic that the boiling point of alcohol is lower than that of water, to generate wine vapor by heating the fermented mash, and then to convert the vapor into wine liquid by cooling, thereby achieving the separation and purification of alcohol from other components. A general wine distiller includes a heat source, a distillation pot, a pot cover, a condenser and a control system. The control system is the key operation of liquor distillation. According to the distillation process of liquor, it controls the burner to burn natural gas to release heat. The high-temperature flue gas transfers heat to the water in the body through the heat transfer system. The water is heated and vaporized to produce saturated steam. The steam rises and enters the mash in the retort barrel of the distillation pot. The wine and spice substances in the mash absorb heat and vaporize and evaporate. The mixed steam enters the condenser through the steam pipe to condense and produce liquor.

[0004] In the traditional distillation process, after the sieve is put on, the mash is lightly packed and evenly spread in the steamer barrel, and then the heat source is turned on to distill the mash. The distillation process is completed in the prescribed operation. However, the traditional distillation process relies too much on the experience and intuition of the winemaker, such as the amount of steam, the distillation time, etc. In addition, the distillation process also involves the wine taking process, which is often manually controlled during the wine distillation process. Due to the differences in operations between different winemakers, the consistency and quality of the wine will be affected. In the prior art, there are also sensors and control systems that are installed to automatically adjust parameters such as steam volume, temperature and distillation time, and use data recording systems to track all parameter changes during each distillation process. However, during the distillation stage, since the mash contains aroma components, the boiling point of the aroma components is different from that of other substances. If the same steam volume is used for continuous distillation, the aroma components will be destroyed due to overheating, which will eventually affect the consistency and quality of the wine. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, one of the objects of the present invention is to provide a control method for a wine distiller to solve the above-mentioned traditional problems.

Through manual intervention, part of the experience and intuition of the winemaker is retained. When the quality of the mash or the heating temperature and time of each heating mode are insufficient during the distillation process, adjustments can be made based on the winemaker's experience to ensure that the aroma components of the mash are retained to the maximum extent, while removing unnecessary substances to ensure the quality consistency of the liquor.

On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements. Example

[0024] A wine distiller comprises a heat source, a wine distiller, a pot cover, a condenser, a wine and water collecting tank and a control system. The heat source adopts a gas burner, and the heat source is placed at the bottom of the wine distiller to directly heat the wine distiller. A labyrinth-like flue and an inner cavity for holding water are arranged in the wine distiller. High-temperature flue gas is discharged along the flue, and water in the inner cavity is heated in the process of being discharged to generate high-temperature steam. A steamer barrel with a plurality of evenly distributed through holes is arranged above the wine distiller, and the steamer barrel is connected with the inner cavity through the through holes. The pot cover covers the wine distiller and is connected with the condenser and the wine and water collecting tank through a connecting pipe. Chilled water is introduced into the condenser, and the wine and water collecting tank is used to collect condensed wine and water.

[0025] The heat source includes a burner, an igniter, a flame detector, a fan, an air filter, an air pressure detector, a combustible gas leak detector, a gas pressure detector and a gas valve. The wine steamer is also provided with a water level detector, a water supply pipeline, a water level control valve, a flue gas pressure detector, a bottom pot wall temperature detector, a furnace pressure detector, a smoke exhaust pipe, a flue gas discharge regulating valve and a sewage pipe.

[0026] The principle is: through the optimal air-fuel ratio, the air and gas are pre-mixed, and then introduced into the gas burner to ignite and burn, generating high-temperature flue gas in the wine steamer. The mash is laid out according to the regulations, such as "loose, light, uniform, thin, accurate, and flat", that is, the mash should be loose when loaded into the steamer, the movement should be quick and light, the steam should be even, the mash should be thin rather than thick, the covering material should be accurate, and the mash in the steamer should be flat. When the mash is placed in the wine steamer, it is placed above the water cavity, covered with a pot cover, and connected to the condenser, wine and water collection tank and other equipment, waiting for subsequent wine steaming, according to the control of the control system, high-temperature steam is generated to distill the mash and collect wine.

[0027] Preferably, the gas burner is a direct-fired ultra-low nitrogen gas burner, the fuel is natural gas, the dynamic pressure of the gas supply is 5kPa-10kPa, and the static pressure of the gas supply is not higher than 15kPa. The fan is an axial flow fan to introduce air into the burner. The flue adopts a three-pass labyrinth flue to achieve the best heat exchange. The control system is also connected with an alarm prompt, an audible and visual prompt, and an emergency stop button for the equipment.

[0028] In one embodiment, the control system includes the following control method: Figure 1 As shown, the control method includes the following steps: S1: Receive the power-on signal, start the machine and perform self-check.

[0029] In this step, after starting up, the system will check according to the safety inspection content. If the inspection result meets the requirements, it will enter the standby state and wait for the start signal. Otherwise, if the inspection result does not meet the requirements, the safety protection program will be started and the start will be prohibited. Among them, the safety inspection content includes whether the water level meets the requirements, whether a combustible gas leak is detected, whether the gas pipeline pressure is lower than the gas pressure low pressure threshold, and whether there are other interlocking signals. If the water level is lower than the minimum water level setting threshold, the safety protection program will be started, the start will be prohibited, the water level control valve will be opened, and water will be added to the working water level setting threshold ±100mL. If the water level is not lower than the minimum water level setting threshold and lower than the working water level setting threshold, the water level control valve will be opened and water will be added to the working water level setting threshold ±100mL. If the water level is higher than the maximum water level setting threshold, the drain valve of the sewage pipe will be opened to drain water to the working water level setting threshold ±100mL. If there is a combustible gas leak or the gas pipeline pressure is lower than the gas pressure low pressure threshold or other interlocking signals, the safety protection program will be started, the start will be prohibited, and the safety protection program can be released only after waiting for processing and normal inspection. In one embodiment, other interlock signals include equipment failure, sound and light alarm, equipment emergency shutdown, etc.

[0030] The above thresholds are all set before starting distillation, or some of the thresholds can be appropriately adjusted during the distillation process. Among them, the combustible gas leakage threshold, the bottom pot wall temperature over-temperature threshold, the furnace pressure over-pressure threshold, the gas pressure low-pressure threshold, the maximum water level setting threshold, the minimum water level setting threshold, the working water level setting threshold, the condensed water temperature setting threshold and the condensed wine setting threshold are factory preset values. Set the corresponding values ​​according to the specifications of the specific wine distiller.

[0032] In this embodiment, the upper sieve load setting threshold is 20%-40% of the rated power of the heat source, and the upper sieve time setting threshold is 30 min-50 min; the distillation load setting threshold is 40%-60% of the rated power of the heat source, and the distillation time setting threshold is 6 min-12 min; the boiling load setting threshold is 60%-100% of the rated power of the heat source, and the boiling time setting threshold is 30 min-50 min. Preferably, the upper sieve load setting threshold is 30% of the rated power of the heat source, and the upper sieve time setting threshold is 40 min; the distillation load setting threshold is 50% of the rated power of the heat source, and the distillation time setting threshold is 10 min; the boiling load setting threshold is 100% of the rated power of the heat source, and the boiling time setting threshold is 40 min. The upper sieve load setting threshold, the distillation load setting threshold, and the boiling load setting threshold can also be adjusted by the load deviation adjustment threshold, respectively. The specific adjustment method can be seen in the subsequent description.

[0033] In other embodiments, the upper zhen load deviation adjustment threshold is divided into 6 gears, of which 3 gears are positive adjustment, i.e., the load is increased, and 3 gears are negative adjustment, i.e., the load is decreased. Specifically, the deviation value of the first gear of the upper zhen is the upper zhen load setting threshold +5°C, the deviation value of the second gear of the upper zhen is the upper zhen load setting threshold +10°C, the deviation value of the third gear of the upper zhen is the upper zhen load setting threshold +15°C, the deviation value of the fourth gear of the upper zhen is the upper zhen load setting threshold -5°C, the deviation value of the fifth gear of the upper zhen is the upper zhen load setting threshold -10°C, and the deviation value of the sixth gear of the upper zhen is the upper zhen load setting threshold -15°C; similarly, the distillation load deviation adjustment threshold is divided into 6 gears, of which 3 gears are positive adjustment, i.e., the load is increased, and 3 gears are negative adjustment, i.e., the load is decreased. Specifically, the deviation value of the first gear of the distillation is the distillation load setting threshold +5°C, the deviation value of the second gear of the distillation is the distillation load setting threshold +10°C, the deviation value of the third gear of the distillation is the distillation load setting threshold +15°C, and the deviation value of the fourth gear of the distillation is The distillation load setting threshold is -5℃, the deviation value of the fifth gear of distillation is the distillation load setting threshold -10℃, and the deviation value of the sixth gear of distillation is the distillation load setting threshold -15℃; the cooking load deviation adjustment threshold is divided into 6 gears, of which 3 gears are positive adjustment, that is, the load is increased, and 3 gears are negative adjustment, that is, the load is reduced. Specifically, the deviation value of the first gear of cooking is the cooking load setting threshold +5℃, the deviation value of the second gear of cooking is the cooking load setting threshold +10℃, the deviation value of the third gear of cooking is the cooking load setting threshold +15℃, the deviation value of the fourth gear of cooking is the cooking load setting threshold -5℃, the deviation value of the fifth gear of cooking is the cooking load setting threshold -10℃, and the deviation value of the sixth gear of cooking is the cooking load setting threshold -15℃. The above thresholds can be appropriately adjusted according to specific requirements. When the adjusted threshold is greater than the maximum rated load, the maximum rated load is used as the final design threshold. When the adjusted threshold is less than the minimum rated load, the minimum rated load is used as the final design threshold.

[0034] S2: Select the heating mode. When the heating mode is the upper-stage mode and the confirmation button is pressed, the system enters the upper-stage state. The system calculates the gas valve current output value according to the upper-stage load setting threshold, and matches the corresponding fan flow according to the current gas valve current output value and the air-fuel ratio, and then executes the ignition process, ignites and burns, and heats to the upper-stage time setting threshold. When the current process countdown enters within 1 minute, the sound control and sound and light prompts are used to indicate that the process is about to end and the next heating mode needs to be selected. Otherwise, when the heating time does not reach the upper-stage time setting threshold, the heating of the upper-stage mode continues to run.

[0035] In this step, the ignition process is: pre-purge, start the fan, gas valve and igniter in sequence, after successful ignition, heat to the upper time setting threshold according to the conditions, when ignition fails, the system will alarm and shut down according to the fixed procedure, and lock the fault.

[0036] In this embodiment, the current gas valve current output value is calculated as follows: According to the formula y 燃气阀电流输出值 =k 上甄负荷设定阈值× x 燃气阀额定电流值 + (1-k 上甄负荷设定阈值 ) × a, calculate the gas valve current output value y 燃气阀电流输出值 , where y 燃气阀电流输出值 is the gas valve current output value, in mA; k 上甄负荷设定阈值 Set the threshold for the upper load, the unit is %; x 燃气阀额定电流值 is the rated current value of the gas valve, in mA; a is the conventional coefficient, in mA.

[0037] The air-fuel ratio is (9-13):1, such as 9:1, 10:1, 11:1, 12:1, 13:1, that is, the mass ratio of air to natural gas = (9-13):1. The specific air-fuel ratio can be set according to specific requirements. The fan flow rate is generally configured through a built-in curve, such as the proportional curve Y=vX. Specifically, different burners match different curves, so I will not repeat them here.

[0038] In this embodiment, x 燃气阀额定电流值 =16mA, a=4 mA. In other embodiments, it is set according to the specific gas valve current output value and the gas valve rated current value.

[0039] In another embodiment, when in the upper-stage mode, an upper-stage load adjustment signal is received, and according to the gear position of the upper-stage load deviation adjustment threshold (such as the gear position is the upper-stage first gear deviation value, the upper-stage load setting threshold is +5°C, if the gear position is the upper-stage fifth gear deviation value, the upper-stage load setting threshold is -10°C, and so on), the current gas valve current output value is adjusted, and the fan flow is adjusted accordingly to adjust the combustion firepower, otherwise no adjustment is made. In this embodiment, a gear adjustment knob is provided on the control panel of the control system, and each gear is adjusted by adjusting the knob. When the gear position of other modes needs to be adjusted, it needs to be reset before the next operation can be performed.

[0040] S3: After the upper-stage mode is completed, the upper-stage mode is released, and the next processing is performed according to the selected heating mode. When the heating mode is selected as the distillation mode and the confirmation button is pressed, the system enters the distillation mode. The system calculates the gas valve current output value according to the distillation load setting threshold, and matches the corresponding fan flow according to the current gas valve current output value and the air-fuel ratio, executes the corresponding combustion firepower, and performs combustion heating until the distillation time setting threshold. When the current process flow countdown enters within 1 minute, the sound control and sound and light prompts are used to indicate that the process flow is about to end and the next heating mode needs to be selected. Otherwise, when the heating time does not reach the distillation time setting threshold, the heating of the distillation mode continues to run.

[0041] In this embodiment, the current gas valve current output value is calculated as follows: According to the formula y 燃气阀电流输出值 =k 蒸馏负荷设定阈值× x 燃气阀额定电流值 + (1-k 蒸馏负荷设定阈值 ) × a, calculate the gas valve current output value y 燃气阀电流输出值 , where y 燃气阀电流输出值 is the gas valve current output value, in mA; k 蒸馏负荷设定阈值 Set a threshold for distillation load in % x 燃气阀额定电流值 is the rated current value of the gas valve, in mA; a is the conventional coefficient, in mA.

[0042] In another embodiment, when in distillation mode, a distillation load adjustment signal is received, and the current gas valve current output value is adjusted according to the degree to which the distillation load deviates from the adjustment threshold, and the fan flow is adjusted accordingly to adjust the combustion firepower, otherwise no adjustment is made.

[0043] S4: After the distillation mode is completed, the distillation mode is released, and the next processing is carried out according to the selected heating mode. When the heating mode is selected as the cooking mode and the confirmation button is pressed, the system enters the cooking mode. The system calculates the gas valve current output value according to the cooking load setting threshold, and matches the corresponding fan flow according to the current gas valve current output value and the air-fuel ratio, executes the corresponding combustion firepower, and performs combustion heating until the cooking time setting threshold. When the current process flow countdown enters within 1 minute, the sound control and sound and light prompts are used to indicate that the process flow is about to end and the next heating mode needs to be selected. Otherwise, when the heating time does not reach the cooking time setting threshold, the heating of the cooking mode continues.

[0044] In this embodiment, the current gas valve current output value is calculated as follows: According to the formula y 燃气阀电流输出值 =k 蒸煮负荷设定阈值× x 燃气阀额定电流值+ (1-k 蒸煮负荷设定阈值 ) × a, calculate the gas valve current output value y 燃气阀电流输出值 , where y 燃气阀电流输出值 is the gas valve current output value, in mA; k 蒸煮负荷设定阈值 Set a threshold for the cooking load in % x 燃气阀额定电流值 is the rated current value of the gas valve, in mA; a is the conventional coefficient, in mA.

[0045] In another embodiment, when in the cooking mode, a cooking load adjustment signal is received, and the current gas valve current output value is adjusted according to the gear position of the cooking load deviating from the adjustment threshold, and the fan flow is adjusted accordingly to adjust the combustion firepower, otherwise no adjustment is made.

[0046] S5: When the steaming mode is completed, the steaming mode is released and the selection of the heating mode is returned to standby mode, waiting for the start of the next round of heating. At this time, before the standby mode, the fan is blown after the purge, and then the standby mode is entered.

[0047] In the above embodiment, if the machine is stopped due to a fault or other accident, the heating mode can be directly adjusted to the corresponding mode according to the material conditions, or the heating can be directly carried out in the order of Zhen-distillation-boiling, etc. In the process of switching modes, each wine-taking operation can be carried out to complete other operations of liquor.

[0048] During the switching process of the heating mode, the combustion is carried out at the lowest load to ensure that steam can continue to be generated in the distillation pot, but the fire is not extinguished in order to wait for the subsequent mode selection and heating.

[0049] During the heating process, since the amount of water is constantly evaporating, this embodiment adopts two modes to keep the water level meeting the requirements. The first mode: before heating, the water level is added to the working water level setting threshold, and then ignited and burned. When the water level is lower than the working water level setting threshold -100mL, the water level control valve is opened to replenish water for the wine steamer. The water level is at the working water level setting threshold ±100mL, and the normal water level is maintained. The second mode: before heating, the water level is added to the maximum water level setting threshold, and then ignited and burned. Before the end of heating, if the water level is not lower than the minimum water level setting threshold, no water is added, that is, generally no water is needed to be added until the end of combustion.
