摘要:
A method of manufacturing a liquid food/beverage packed in a container obtained by diluting a raw material liquid with a diluting liquid having a lower viscosity than that of the raw material liquid includes: a diluting liquid heating step of heating the diluting liquid up to a higher temperature than that of the raw material liquid before being mixed with the raw material liquid; a primary heating/diluting step of swirling the diluting liquid in the raw material liquid to generate a swirl flow thereby to dilute the raw material liquid while heating the raw material liquid through heat convection of the swirl flow; and a secondary heating/sterilizing step of, after the primary heating/diluting step, heating and sterilizing a mixed liquid of the raw material liquid and the diluting liquid by conductive heat.
