Liquid coffee sterilization system that minimizes the deterioration of coffee's unique taste and aroma

摘要

The present invention relates to a liquid coffee sterilization system that minimizes the deterioration of the inherent taste and aroma of coffee, and is capable of sterilizing liquid coffee, which is difficult to sterilize due to solid components, to an almost sterilization level while preserving the original taste and aroma of coffee. it was made appropriate. The present invention is provided with a first heat exchanger and a second heat exchanger through which the liquid coffee transferred by the pumping of the transfer pump passes, and in the first heat exchanger, the liquid coffee is rapidly heated and sterilized while passing through a high-temperature heating medium, In the second heat exchanger, the liquid coffee sterilized in the first heat exchanger is rapidly cooled while passing through low-temperature cooling water. It is characterized in that it is sequentially arranged in the vicinity so that it can be rapidly cooled.
