Abstract:
본 발명은 액상의 용매없이 코팅제를 박테리오신에 건식으로 코팅하는 단계를 포함하는, 건식코팅된 박테리오신의 제조방법 및 전기 방법으로 제조된 건식코팅된 박테리오신에 관한 것이다. 본 발명의 박테리오신을 코팅하는 방법은 박테리오신과 코팅제를 1:1 내지 10:1(w/w)로 혼합하고, 혼합물을 하이브리디제이션 시스템에 주입하는 단계; 및, 하이브리디제이션 시스템을 이용하여 박테리오신을 건식으로 코팅하는 단계를 포함한다. 본 발명의 방법에 의하여 제조된 건식코팅된 박테리오신은 코팅되지 전과 동일한 수준의 항균활성을 나타내었을 뿐만 아니라, 건식코팅된 박테리오신을 장기간 동안 상온에서 보관한 경우, 코팅된 박테리오신의 항균활성이 코팅되지 않은 박테리오신에 비하여 비교적 높은 수준으로 유지됨을 알 수 있었으므로, 박테리오신을 유효성분으로 포함하는 식품 및 화장품의 개발에 널리 활용될 수 있을 것이다. 박테리오신, 건식코팅, 하이브리디제이션 시스템
Abstract:
Disclosed is a customized heat pump drying apparatus for manufacturing high quality dried pepper. The customized heat pump drying apparatus for manufacturing high quality dried pepper of the present invention comprises: a housing with an opening and closing door; a drying chamber arranged in the housing, wherein the drying chamber includes a drying space on which multiple wicker trays are mounted to accommodate whole pepper and an air circulation passage allowing dry air with higher temperature than room temperature to be supplied from one side of the drying space to the drying space and to be discharged to the opposite side through the wicker trays; a circulation fan arranged in a discharging unit direction of the air circulation passage and forcibly discharging and circulating the dry air in the drying space; a heat pump device provided on an upper surface of the drying chamber, heats the air circulated by the circulation fan through an air circulation passage and passing through a condenser and an evaporator, and removes moisture; and a control unit which controls the amount of external air introduced through the air circulation passage based on a detection signal of a temperature sensor installed in the drying space, controls an intake valve installed on an external air inlet to control the temperature of circulated air, operates and controls the circulation fan, and controls the heat pump device. According to the present invention, the customized heat pump drying apparatus can produce high quality dried pepper of the sunlight dried pepper grade by controlling dry temperature, dry time, and moisture.
