연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

In a method of controlling progressive freeze-concentration by circulating a cooling medium through a cooling-medium flow route while circulating a target liquid for freeze-concentration through a target-liquid flow route so as to gradually form ice crystals on wall surfaces of the target-liquid flow route, a volume expansion detecting device is used to detect volume expansion of the target liquid and thickness of the ice crystals in the target-liquid flow route is obtained from the volume expansion detected by this volume expansion detecting device. The flow rate of the target liquid and the growth speed of the ice front in the target-liquid flow route are controlled to become equal respectively to a set flow rate value and to a set growth speed value by carrying out operations of specified kinds based on the crystal thickness thus obtained such as calculating inner diameter of the ice crystals, calculating a required flow volume of the target liquid in the target-liquid flow route from the calculated inner diameter and the set flow rate, and adjusting circulation volume of the target liquid such that measured flow volume of the target liquid becomes equal to the required flow volume, and calculating actual growth speed of the ice front from the obtained crystal thickness and adjusting temperature and/or circulation volume of the cooling medium such that the calculated actual growth speed becomes equal to the set growth speed value.

What is claimed is: 1. A method of controlling progressive freeze-concentration, said method comprising the steps of: circulating a cooling medium through a cooling-medium flow route of a freeze-concentration apparatus while circulating a target liquid for freeze-concentration through a target-liquid flow route of said freeze-concentration apparatus, thereby gradually forming ice crystals on wall surfaces of said target-liquid flow route in freeze-concentration of said target liquid; connecting to said target-liquid flow route a volume expansion detecting means for detecting volume expansion of said target liquid; obtaining thickness of said ice crystals in said target-liquid flow route from volume expansion detected by said volume expansion detecting means; and controlling flow rate of said target liquid and growth speed of ice front in said target-liquid flow route to become equal respectively to a set flow rate value and to a set growth speed value by carrying out Operation A and Operation B based on said obtained thickness; wherein said Operation A comprises calculating inner diameter of said ice crystals in said target-liquid flow route from said obtained thickness, calculating a required flow volume of said target liquid in said target-liquid flow route from said calculated inner diameter and said set flow rate, and adjusting circulation volume of said target liquid such that measured flow volume of said target liquid inside said target-liquid flow route becomes equal to said required flow volume; and wherein said Operation B comprises calculating actual growth speed of said ice front in said target-liquid flow route from said obtained thickness and adjusting at least one selected from the group consisting of temperature and circulation volume of said cooling medium such that said calculated actual growth speed becomes equal to said set growth speed value. 2. The method of claim 1 wherein said freeze-concentration apparatus comprises cylindrical double tubes each having said target-liquid flow route formed inside and said cooling-medium flow route formed outside. 3. The method of claim 2 wherein said freeze-concentration apparatus comprises two or more cylindrical double tubes, the target-liquid flow routes of said two or more cylindrical double tubes being connected so as to together form a circulating flow route. 4. The method of claim 1 wherein said volume expansion detecting means determines amount of said target liquid spilled out of said target-liquid flow route by detecting one quantity selected from the group consisting of pressure, weight and liquid surface level. 5. The method of claim 1 wherein said volume expansion detecting means determines amount of said target liquid spilled out of said target-liquid flow route by detecting integrated flow volume of said target liquid spilled out of said target-liquid flow route. 6. The method of claim 4 wherein said circulation volume of said target liquid is adjusted in said Operation A by controlling rotary motion of a target-liquid circulating pump by a frequency control. 7. The method of claim 5 wherein said circulation volume of said target liquid is adjusted in said Operation A by controlling rotary motion of a target-liquid circulating pump by a frequency control. 8. The method of claim 6 wherein the temperature of said cooling medium is adjusted in said Operation B by controlling a cooler which is adapted to cool said cooling medium. 9. The method of claim 7 wherein the temperature of said cooling medium is adjusted in said Operation B by controlling a cooler which is adapted to cool said cooling medium. 10. The method of claim 6 wherein the temperature of said cooling medium is adjusted in said Operation B by controlling flow volume of a portion of said cooling medium that is supplied from a cooling-medium tank connected to a cooler to an inlet to said cooling-medium flow route and of another portion of said cooling medium that is discharged from an outlet from said cooling-medium flow route and returned to said inlet to said cooling-medium flow route without passing through said cooling-medium tank. 11. The method of claim 7 wherein the temperature of said cooling medium is adjusted in said Operation B by controlling flow volume of a portion of said cooling medium that is supplied from a cooling-medium tank connected to a cooler to an inlet to said cooling-medium flow route and of another portion of said cooling medium that is discharged from an outlet from said cooling-medium flow route and returned to said inlet to said cooling-medium flow route without passing through said cooling-medium tank. 12. The method of claim 6 wherein the circulation volume of said cooling medium is adjusted in said Operation B by controlling rotary motion of a cooling-medium circulating pump by a frequency control. 13. The method of claim 7 wherein the circulation volume of said cooling medium is adjusted in said Operation B by controlling rotary motion of a cooling-medium circulating pump by a frequency control. 14. The method of claim 8 wherein the circulation volume of said cooling medium is adjusted in said Operation B by controlling rotary motion of a cooling-medium circulating pump by a frequency control. 15. The method of claim 9 wherein the circulation volume of said cooling medium is adjusted in said Operation B by controlling rotary motion of a cooling-medium circulating pump by a frequency control. 16. The method of claim 10 wherein the circulation volume of said cooling medium is adjusted in said Operation B by controlling rotary motion of a cooling-medium circulating pump by a frequency control. 17. The method of claim 11 wherein the circulation volume of said cooling medium is adjusted in said Operation B by controlling rotary motion of a cooling-medium circulating pump by a frequency control.
