Abstract: The present invention relates to a method for producing high-quality drinks filled in containers, which is characterized in that containers are made to have a nitrogen gas atmosphere to be in a substantially deoxidated condition prior to being filled with drinks. According to the method of the present invention, the inside of empty containers is made in a substantially oxygen-free condition, and drinks as prepared in the presence of an inert gas or in a deoxidated condition are filled into the containers. Therefore, all steps constituting the method, including the step of preparing raw materials through the step of filling and sealing drinks in containers, can be conducted all the way in a deoxidated condition to give high-quality drinks filled in containers.

Abstract: The roasting body is composed of a roasting body, a rotary drum supported on the inside of the roasting body to rotate in a horizontal attitude to accommodate and stir the coffee beans, infrared heaters disposed on the inner wall surface of the roasting body to surround the rotary drum in order to heat the coffee beans accommodated in the rotary drum by radiant heat, and a circulating path to circulate the hot air in the rotary drum into the roasting body in order to utilize the thermal energy effectively.
