In such a molding apparatus 10, food products are molded in the following manner. That is, when the material 3 kneaded and melted in the extruder main body 1 is extruded from the die 2, the upper part of the material is exposed to the atmosphere or foamed by being blown with hot air by the nozzle 15. A swelling layer 3a is formed. On the other hand, the lower part of the material 3 is cooled by the cooling water in the lower cooling chamber 12b of the pre-cooling chamber 112 at the same time as it is extruded from the die 2, and forms the skin layer 3b without foaming (first treatment step ).

After that, the material 3 is sent into the channel 11,
By setting the cross-sectional shape of the flow path 11 to a predetermined shape, the cross-sectional shape of the material 3, that is, the food product, is also determined. Therefore, at this stage, material 3
has a swelling layer 3a and a skin layer 3b, and is given a predetermined cross-sectional shape. The material 3 is further subjected to a cooling process in the front and rear cooling chambers 12 and 13, and corrections such as slack are made in the vacuum chamber 14 (second process step), and is formed into a food product as shown in FIG.
