PROCESS FOR PRODUCING FOOD ENCLOSED IN SEALED CONTAINER

摘要

A process for producing a food enclosed in sealed containers which is free from a trouble during production that water spills from the containers or a perforating jig falls into the containers and in which a heat treatment can be conducted without causing quality unevenness. A food (1) is placed in containers (2). The containers (2) filled with the food (1) are sealed with a primary film (4) having a through-hole (3) to obtain a sealed-container-packed food (A). This sealed-container-packed food (A) is disposed in a heating vessel (7) having a steam inlet part (5) and a steam discharge part (6). Steam is introduced through the steam inlet part (5) into the heating vessel (7) to heat the sealed-container-packed food (A) while discharging the steam through the steam discharge part (6). Thereafter, a secondary film (8) is bonded to each container through the primary film (4) so as to cover the through-hole (3).
