Description

에타놀연속발효시스템{Ethanol Continuous Fermentation System}Ethanol Continuous Fermentation System

본 발명은 에타놀 연속발효 시스템에 관한 것으로서, 발효를 쉬지않고 연속적으로 진행하여, 생산성 향상 및 원가 절감을 할 수 있도록한 것이다.The present invention relates to a ethanol continuous fermentation system, to continuously proceed without fermentation, thereby improving productivity and cost reduction.

초기 발효탱크에 발효재료가 없으면 발효재료 감지장치에 의해 감지되어 시스템 제어장치로 통보되고, 시스템 제어장치는 발효재료 저장탱크에 저장되어 있던 발효재료를 발효탱크로 공급한다. 이 발효재료는 미리 투입된 발효균에 의해 발효가 시작되고, 에타놀의 농도가 일정 수준이상이 되면 에타놀 감지장치가 작동되어 시스템 제어장치로 통보되고, 시스템 제어장치가 저온 추출장치를 작동시켜 에타놀이 추출되어 에타놀 저장탱크에 저장된다. 발효가 계속되어 발효탱크에서 발효재료가 부족해지면 발효재료 감지장치가 작동하여 시스템 제어장치로 통보되고 시스템 제어장치는 발효재료를 발효재료 저장탱크에서 발효탱크로 공급시킨다. 이런 방식으로 발효재료에서 제품생성까지 연속적으로 계속 발효를 진행하는 것이 본 발명의 특징이다.If there is no fermentation material in the initial fermentation tank, it is detected by the fermentation material detection device and notified to the system control device, and the system control device supplies the fermentation material stored in the fermentation material storage tank to the fermentation tank. The fermentation material is fermented by fermented bacteria, and when the concentration of ethanol is higher than a certain level, the ethanol detector is activated and notified to the system controller, and the system controller operates the low temperature extractor to extract ethanol. Stored in ethanol storage tanks. If fermentation continues and there is a shortage of fermentation material in the fermentation tank, the fermentation material detection device is activated and notified to the system controller, and the system controller supplies fermentation material from the fermentation material storage tank to the fermentation tank. It is a feature of the present invention to continuously proceed fermentation from fermentation material to product production in this way.

또 발효재료 저장탱크와 발효탱크에서 잡균의 번식을 방지하기 위하여 발효재료 저장탱크에 저장된 발효재료는 오존 살균 장치에 의하여 살균이실시되는데, 이 오존은 오존 발생기로 부터 공급된다.The fermentation material stored in the fermentation material storage tank is sterilized by an ozone sterilizer in order to prevent propagation of various germs in the fermentation material storage tank and the fermentation tank. The ozone is supplied from an ozone generator.

특히 에타놀 추출시 에타놀이 물과 잘 혼합되어 40℃이상의 고온으로 가열하여 물과 발효 생성물을 분리해야하므로 고열을 사용하지 않고 저온추출장치( 초음파 추출, 가스방울 추출, 진공추출, 분무추출, 에타놀 용매 순환 추출, 에타놀 필터 추출 )를 이용하여 물과 에타놀을 분리시키므로서, 고온 증류시 발효균이 죽어서 재 사용할 수 없는 단점을 보완하여, 기존에 사용하던 발효균을 계속 재 사용하여 고 효율로 연속적으로 발효를 진행할 수 있는 기술이다.In particular, when ethanol is extracted, ethanol is well mixed with water and heated to a high temperature of 40 ° C. or higher to separate water and fermentation products. Therefore, a low temperature extraction device (ultrasound extraction, gas bubble extraction, vacuum extraction, spray extraction, ethanol solvent, etc.) is used without using high heat. By separating the water and ethanol using circulating extraction and ethanol filter extraction), the fermentation bacteria dies and cannot be reused during high temperature distillation, and the existing fermentation bacteria are continuously reused to continuously ferment with high efficiency. It is a technology that can proceed.

종래에는 물과 에타놀을 분리할 경우에는 물과 에타놀과 발효균을 모두 40℃이상의 고온으로 가열하여 물과 에타놀을 분리하므로 이 고온에서 발효균이 죽어버리므로 재사용할 수가 없어, 다음 발효시에는 다시 발효균을 배양하여야 하므로 발효가 불연속적으로 진행되고, 발효시간이 길어지고 발효균 배양에 여분의 발효재료가 사용되어야하므로 발효 효율도 저하되는 단점이 있다.Conventionally, when water and ethanol are separated, both water, ethanol, and fermentation bacteria are heated to a high temperature of 40 ° C. or higher to separate water and ethanol. Therefore, fermentation bacteria die at this high temperature, and thus cannot be reused. Since the fermentation is discontinuously progressed, the fermentation time is lengthened and the extra fermentation material must be used for culturing the fermentation bacteria.

본 발명은 에타놀을 저온에서 추출하므로 발효균과 효소를 파괴하지 않고 계속 재 사용할 수 있어 발효과정을 연속적으로 진행하기 위한 것이다. 저온 추출 장치로는 초음파 추출, 가스방울 추출, 진공추출, 분무추출, 에타놀 용매 순환 추출, 에타놀 필터 추출을 사용 한다.The present invention is to extract the ethanol at a low temperature, so that it can be reused continuously without destroying the fermentation bacteria and enzymes is to continue the fermentation process continuously. Ultrasonic extraction, gas extraction, vacuum extraction, spray extraction, ethanol solvent circulation extraction, ethanol filter extraction are used as low temperature extraction apparatus.

본 발명은 발효탱크, 시스템 제어장치, 에타놀 감지장치, 발효재료 감지장치, 저온 추출( 초음파 추출, 가스방울 추출, 진공추출, 분무추출, 에타놀 용매 순환 추출, 에타놀 필터 추출)장치, 발효재료 저장탱크, 오존 발생장치, 오존 살균장치, 에타놀 저장장치로 구성되어 있다The present invention fermentation tank, system control device, ethanol detection device, fermentation material detection device, low temperature extraction (ultrasound extraction, gas extraction, vacuum extraction, spray extraction, ethanol solvent circulation extraction, ethanol filter extraction) device, fermentation material storage tank Composed of ozone generator, ozone sterilizer and ethanol storage

에타놀을 저온에서 추출하므로 발효균과 효소를 파괴하지않고 계속 사용하므로 발효공정이 연속적으로 진행되어 발효시간의 단축( 발효균 증식 시간 단축 ) 및 발효균 배양액 절감으로 발효재료를 절감할 수 있는 효과가 있다.Since ethanol is extracted at a low temperature, the fermentation process is continuously used without destroying the fermentation bacteria and enzymes, and thus the fermentation process is continuously performed, thereby reducing the fermentation material by reducing the fermentation time and reducing the fermentation culture.
