Description

생맥주통 내 맥주의 이산화탄소 농도 유지를 위한 시스템System for maintaining carbon dioxide concentration of beer in draft beer keg
본 발명은 생맥주통 내 맥주의 이산화탄소 농도 유지를 위한 시스템에 관한 것으로, 생맥주통 내 압력과 온도를 측정하고 온도변화에 따른 보정계수를 기반으로 보정된 압력값을 산출하고 보정된 압력값과 기설정된 압력값의 차이만큼 이산화탄소를 배출하거나 주입하여 생맥주통 내 맥주의 이산화탄소 농도를 유지하는 시스템에 관한 것이다.The present invention relates to a system for maintaining the carbon dioxide concentration of beer in a draft beer barrel, which measures the pressure and temperature in the draft beer barrel, calculates a corrected pressure value based on a correction coefficient according to temperature change, and calculates a corrected pressure value and a preset value. It relates to a system for maintaining the carbon dioxide concentration of beer in a draft beer barrel by discharging or injecting carbon dioxide as much as the difference in pressure value.
맥주 산업에서 기존의 맥주는 대량 생산된 병맥주나 캔맥주가 주류를 이뤄 판매되고 소비되었으나, 소득수준 상승과 생맥주나 소규모로 양조된 맥주에 대한 수요가 증가하는 추세이다. 따라서 주류를 전문으로 판매하는 곳에서는 생맥주통에 맥주를 담아 보관하다가 주문에 따라 즉석에서 생맥주를 추출하여 고객에게 제공하는 것이 일반적이다. 일반적으로 맥주의 CO2의 함량이 0.32% 이하면 김빠진 맛을 느끼게 된다.Existing beer in the beer industry was sold and consumed as the mainstream of mass-produced bottled or canned beer, but with rising income levels, demand for draft beer or beer brewed on a small scale is on the rise. Therefore, it is common for places that specialize in alcoholic beverages to store beer in draft beer kegs and then extract draft beer on the spot according to the order and provide it to customers. In general, if the CO2 content of beer is less than 0.32%, you will feel the lack of taste.
생산된 맥주는 온도가 낮을수록, 압력이 높을수록 CO2의 포화도는 높아진다. 최종 맥주에는 0.5%의 CO2가 함유되어야 하므로 숙성조에서는 맥주이송 등으로 손실을 감안하여 0.5% 이상의 CO2가 포화되도록 한다. 이렇게 생산된 맥주를 고객에게 신선하고 맛 좋은 상태로 제공하기 위해서는 생맥주통(Keg) 내 맥주의 이산화탄소 농도를 일정하게 유지하는 것이 중요하다. 생맥주를 추출하는 방식은 크게 두가지로 나뉠 수 있는데 냉장보관과 상온보관 방식이 있다. 냉장보관 방식의 경우 냉장기능의 설정에 따라 3~5도 정도의 온도변화가 발생할 수 있고, 제상기능이 있는 경우 15~20도까지 온도변화가 발생하게 된다. 상온에서 생맥주를 추출하는 방식은 추출하는 순간에만 순간냉각기를 이용하여 추출하는 방식인데, 상온에서 보관하더라도 낮과 밤이 바뀜에 따라, 또한 에어컨이나 히터 등의 주변 환경에 따라 온도변화가 발생한다.The lower the temperature and the higher the pressure, the higher the saturation of CO2. Since the final beer must contain 0.5% CO2, in the maturation tank, CO2 of 0.5% or more is saturated, taking into account losses due to beer transfer, etc. In order to provide the beer produced in this way to customers in a fresh and tasty state, it is important to maintain a constant carbon dioxide concentration of the beer in the draft beer keg. There are two main ways to extract draft beer: refrigeration storage and room temperature storage. In the case of the refrigeration storage method, a temperature change of about 3 to 5 degrees may occur according to the setting of the refrigeration function, and in the case of a defrost function, a temperature change of up to 15 to 20 degrees may occur. The method of extracting draft beer at room temperature is a method of extracting using an instantaneous cooler only at the moment of extraction. Even if stored at room temperature, temperature changes occur according to the change of day and night and the surrounding environment such as air conditioners or heaters.
생맥주통(Keg)의 온도 변화가 생기면 맥주 내 이산화탄소 용해도가 달라져서 맥주를 추출할 때 거품이 유발된다. 특히 생맥주통(Keg) 내 맥주의 보관기간이 길어질수록, 그리고 남은 맥주의 양이 적어질수록 더 많은 거품이 유발된다.When the temperature of the draft beer keg changes, the solubility of carbon dioxide in the beer changes, causing bubbles when brewing the beer. In particular, as the storage period of beer in the draft beer keg (Keg) increases and the remaining amount of beer decreases, more bubbles are generated.
그러나 생맥주통(Keg) 내 맥주의 이산화탄소 농도를 조절하는 기존 레귤레이터들은 생맥주통(Keg) 내 압력값을 측정하여 압력을 조절하는 방식이며, 온도변화를 고려하더라도 온도변화를 레귤레이터의 동작에 적용하는 방식에 있어 부정확하기 때문에 압력과 함께 온도변화까지 고려하여 생맥주통(Keg) 내 맥주의 이산화탄소 농도를 온도변화와 상관없이 균일하게 조절 가능한 레귤레이터는 전무한 실정이다.However, existing regulators that control the carbon dioxide concentration of beer in the draft beer keg measure the pressure value in the draft beer keg to adjust the pressure, and apply the temperature change to the operation of the regulator even considering the temperature change. There is no regulator that can uniformly adjust the carbon dioxide concentration of beer in a draft beer keg regardless of temperature change by considering temperature change as well as pressure.

이하, 도 1 내지 도 4를 통해 본 발명의 실시예에 따른 생맥주통(500) 내 맥주의 이산화탄소 농도 유지를 위한 시스템을 설명하도록 한다.Hereinafter, a system for maintaining the carbon dioxide concentration of beer in a draft beer barrel 500 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.
도 1은 본 발명의 일 실시예에 따른 생맥주통(500) 내 맥주의 이산화탄소 농도 유지를 위한 시스템을 개략적으로 나타내는 도면이고, 도 4는 온도별 맥주 내 탄산가스 용해량을 나타내는 그래프이다.1 is a diagram schematically showing a system for maintaining the carbon dioxide concentration of beer in a draft beer barrel 500 according to an embodiment of the present invention, and FIG. 4 is a graph showing the amount of carbon dioxide dissolved in beer by temperature.
도 4를 참조하면, 생맥주통(500) 내 맥주의 탄산가스 용해량은 온도에 따라 차이가 있다. 즉, 온도가 낮을 때 맥주 내에 이산화탄소가 더 많이 용해되며, 온도가 높아질수록 이산화탄소 농도가 낮아진다. 그런데 온도가 높아 탄산가스 용해도가 떨어질수록 맥주 내의 CO2는 기체, 즉 거품으로 변하는 힘이 강해지면서 추출 시 거품이 과도하게 발생하게 된다. 따라서 거품의 과도한 발생을 막기 위해서는 온도가 높을수록 더 많은 압력값이 필요하고 온도가 낮아질수록 적은 압력값이 필요하다. 즉, 온도 변화에 따라 생맥주통(500) 내 맥주의 이산화탄소 농도 유지를 위한 관리가 필요하다.Referring to FIG. 4 , the amount of carbon dioxide dissolved in beer in the draft beer barrel 500 varies depending on the temperature. That is, when the temperature is low, more carbon dioxide is dissolved in the beer, and the higher the temperature, the lower the carbon dioxide concentration. However, as the temperature rises and the solubility of carbon dioxide gas decreases, the CO2 in beer becomes a gas, that is, the stronger the power to change into bubbles, resulting in excessive bubbles during extraction. Therefore, in order to prevent excessive foaming, the higher the temperature, the higher the pressure value, and the lower the temperature, the lower the pressure value. That is, management for maintaining the carbon dioxide concentration of beer in the draft beer barrel 500 according to temperature change is required.
따라서 온도 변화에 따른 CO2 용해도를 근거로 보정계수를 산출하여 이를 압력센서에 의해 감지된 압력값에 적용하여 보정된 압력값을 생성해야 한다.Therefore, it is necessary to calculate the correction coefficient based on the solubility of CO2 according to the temperature change and apply it to the pressure value sensed by the pressure sensor to generate the corrected pressure value.

도 3은 본 발명의 일 실시예에 따른 생맥주통(500) 내 맥주의 이산화탄소 농도 유지를 위한 시스템에서 이산화탄소 농도 유지를 위해 제어 기능을 수행하는 과정을 나타내는 흐름도이다.3 is a flowchart illustrating a process of performing a control function to maintain the carbon dioxide concentration in a system for maintaining the carbon dioxide concentration of beer in a draft beer barrel 500 according to an embodiment of the present invention.
먼저, 사용자 단말(300)로부터 기설정된 압력값 및 보정계수를 수신하는 단계(S100), 제어장치(200)가 압력센서 및 온도센서를 통해 생맥주통(500) 내 압력 및 온도를 측정하는 단계(S110), 측정된 온도값을 기반으로 온도변화에 따른 보정계수를 적용하여 보정된 압력값을 생성하는 단계(S120), 보정된 압력값과 기설정된 압력값을 비교하는 단계(S130, S150), 비교 결과에 따라 배출밸브를 개방하고 이산화탄소를 배출하는 단계(S140) 또는 주입밸브를 개방하여 이산화탄소를 주입하는 단계(S160) 또는 주기적인 시간 간격으로 생맥주통(500)내 맥주의 이산화탄소 농도 유지를 위한 단계(S110)로 이루어진다. 생맥주통(500) 내 맥주가 다 소비되기 전까지는 위에서 설명한 이산화탄소 농도 유지를 위해 제어 기능을 수행할 수 있다.First, a step of receiving a preset pressure value and a correction coefficient from the user terminal 300 (S100), and a step of measuring the pressure and temperature in the draft beer barrel 500 by the controller 200 through a pressure sensor and a temperature sensor ( S110), generating a corrected pressure value by applying a correction coefficient according to temperature change based on the measured temperature value (S120), comparing the corrected pressure value with a preset pressure value (S130, S150), According to the comparison result, the step of opening the discharge valve and discharging carbon dioxide (S140) or opening the injection valve and injecting carbon dioxide (S160) or maintaining the carbon dioxide concentration of beer in the draft beer barrel 500 at regular time intervals It consists of step (S110). Until the beer in the draft beer barrel 500 is consumed, the above-described control function may be performed to maintain the carbon dioxide concentration.
S100 단계에서, 사용자에 의해 입력된 기설정된 압력값 및 보정계수가 서버(100)로 수신되면, 서버(100)는 기설정된 압력값 및 보정계수를 제어장치(200)로 전송한다. 제어장치(200)는 기설정된 압력값 및 보정계수를 수신하여 생맥주통(500) 내 맥주의 이산화탄소 농도 유지를 위한 제어 기능을 수행한다.In step S100, when the server 100 receives the preset pressure value and correction coefficient input by the user, the server 100 transmits the preset pressure value and correction coefficient to the controller 200. The controller 200 performs a control function for maintaining the carbon dioxide concentration of beer in the draft beer barrel 500 by receiving the preset pressure value and the correction coefficient.
S110 단계에서, 제어장치(200)가 압력센서 및 온도센서를 통해 생맥주통(500) 내 압력 및 온도를 측정한다.In step S110, the controller 200 measures the pressure and temperature in the draft beer barrel 500 through the pressure sensor and the temperature sensor.
S120 단계에서, 제어장치(200)는 측정된 온도값을 기반으로 온도변화에 따른 보정계수를 압력값에 적용하여 보정된 압력값을 생성한다.In step S120, the controller 200 generates a corrected pressure value by applying a correction coefficient according to temperature change to the pressure value based on the measured temperature value.
S130 단계 및 S150 단계에서, 제어장치(200)는 보정된 압력값과 기설정된 압력값을 비교하는데, 먼저 보정된 압력값이 기설정된 압력값보다 큰지 여부를 판단하고 큰 경우 S140 단계로 진행하여 이산화탄소 배출을 위한 기능을 수행한다.In steps S130 and S150, the control device 200 compares the corrected pressure value with the preset pressure value. First, it determines whether the corrected pressure value is greater than the preset pressure value, and if it is greater, proceeds to step S140 to obtain carbon dioxide. It performs a function for discharge.
S140 단계에서, 제어장치(200)는 현재 보정된 압력값과 기설정된 압력값의 차이에 해당하는 용량의 이산화탄소를 배출하기 위해 배출밸브를 개방한다. 정해진 용량의 이산화탄소 배출이 완료되면 배출밸브를 폐쇄하고, 기설정된 시간 간격이 도래하면 다시 S110 단계로 진행하여 압력센서 및 온도센서를 통해 생맥주통(500) 내 압력 및 온도를 측정한다.In step S140, the controller 200 opens the discharge valve to discharge carbon dioxide in a capacity corresponding to the difference between the current corrected pressure value and the preset pressure value. When the discharge valve of the predetermined capacity is completed, the discharge valve is closed, and when the predetermined time interval arrives, the process proceeds to step S110 again to measure the pressure and temperature in the draft beer barrel 500 through the pressure sensor and the temperature sensor.
만일 S130 단계에서 보정된 압력값보다 기설정된 압력값이 크지 않은 경우, S150 단계로 진행하여 보정된 압력값이 기설정된 압력값과 동일한지 여부를 판단한다(S150).If the preset pressure value is not greater than the corrected pressure value in step S130, proceed to step S150 to determine whether the corrected pressure value is the same as the preset pressure value (S150).
S150 단계에서, 제어장치(200)가 보정된 압력값과 기설정된 압력값이 동일한지 여부를 판단할 때, 동일한 값이 아니더라도 기설정된 오차범위 이내인 경우, 주기적인 시간 간격으로 생맥주통(500)의 제어를 위한 동작을 수행하기 위해 단계(S110)로 진행할 수 있다. 즉, 보정된 압력값과 기설정된 압력값의 차이가 기설정된 오차범위 이내인 경우, 예를 들어 차이가 1%나 2% 또는 5(kg/cm3) 미만인 경우에는 별도의 이산화탄소 주입 또는 배출 동작을 수행하지 않고 S110 단계로 진행하여, 주기적인 시간 간격으로 생맥주통(500) 내 압력값과 온도값을 기반으로 보정된 압력값을 도출하여 기설정된 압력값과 비교함으로써 생맥주통(500)의 제어를 위한 동작을 수행하도록 할 수 있다.In step S150, when the control device 200 determines whether the calibrated pressure value and the preset pressure value are the same, even if they are not equal, if they are within the preset error range, the draft beer barrel 500 It can proceed to step S110 in order to perform an operation for control of. That is, when the difference between the corrected pressure value and the preset pressure value is within a preset error range, for example, when the difference is less than 1% or 2% or 5 (kg/cm 3 ), a separate carbon dioxide injection or discharge operation The process proceeds to step S110 without performing the control of the draft beer barrel 500 by deriving a corrected pressure value based on the pressure value and temperature value in the draft beer barrel 500 at regular time intervals and comparing it with the preset pressure value. It can be made to perform an operation for.
만일 S150 단계에서 보정된 압력값이 기설정된 압력값과 동일하지 않은 경우, 남은 경우는 보정된 압력값이 기설정된 압력값보다 작은 경우이므로 S160 단계로 진행한다.If the corrected pressure value in step S150 is not the same as the preset pressure value, the remaining cases are the case where the corrected pressure value is smaller than the preset pressure value, so the process proceeds to step S160.
S160 단계에서, 제어장치(200)는 현재 보정된 압력값과 기설정된 압력값의 차이에 해당하는 용량의 이산화탄소를 주입하기 위해 주입밸브를 개방한다.In step S160, the control device 200 opens the injection valve to inject carbon dioxide in a capacity corresponding to the difference between the current corrected pressure value and the preset pressure value.
정해진 용량의 이산화탄소 주입이 완료되면 주입밸브를 폐쇄하고, 기설정된 시간 간격이 도래하면 다시 S110 단계로 진행하여 압력센서 및 온도센서를 통해 생맥주통(500) 내 압력 및 온도를 측정한다.When the injection of the predetermined amount of carbon dioxide is completed, the injection valve is closed, and when the predetermined time interval arrives, the process proceeds to step S110 again to measure the pressure and temperature in the draft beer barrel 500 through the pressure sensor and the temperature sensor.
따라서 주기적인 시간 간격에 따라 제어장치(200)는 압력센서 및 온도센서를 통해 생맥주통(500) 내 압력 및 온도를 측정하는 단계(S110), 측정된 온도값을 기반으로 온도변화에 따른 보정계수를 적용하여 보정된 압력값을 생성하는 단계(S120), 보정된 압력값과 기설정된 압력값을 비교하는 단계(S130, S150), 비교 결과에 따라 배출밸브를 개방하고 이산화탄소를 배출하는 단계(S140) 또는 주입밸브를 개방하여 이산화탄소를 주입하는 단계(S160) 또는 주기적인 시간 간격으로 생맥주통(500)내 맥주의 이산화탄소 농도 유지를 위한 단계(S110)로 순환하며 제어 기능을 수행함으로써 지속적으로 생맥주통(500) 내 맥주의 이산화탄소 농도를 유지할 수 있다. Therefore, the control device 200 measures the pressure and temperature in the draft beer barrel 500 through the pressure sensor and the temperature sensor at a periodic time interval (S110), and the correction coefficient according to the temperature change based on the measured temperature value generating a corrected pressure value by applying (S120), comparing the corrected pressure value with a preset pressure value (S130, S150), opening the discharge valve according to the comparison result and discharging carbon dioxide (S140). ) or the step of injecting carbon dioxide by opening the injection valve (S160) or the step of maintaining the carbon dioxide concentration of beer in the draft beer barrel 500 at regular time intervals (S110) to continuously perform the control function while circulating to the draft beer barrel (500) can maintain the carbon dioxide concentration of my beer.
