てある。
An extruder puts grains such as rice and soybeans, their processed products (flour, starch, etc.) and other food materials into a barrel, kneads, heats, and pressurizes them by rotating a screw, and then expels the kneaded material from the tip of the barrel. It is a discharge device, and the tip of the barrel has a narrow flow path.

結し、混練物を冷却してフラツシユ蒸発を防止し
ている。 The kneaded material discharged from the barrel is instantaneously reduced to atmospheric pressure, so that water rapidly evaporates into a puffed product. Therefore, in order to produce an unexpanded product, a cooling device is connected to the tip of the barrel to cool the kneaded material and prevent flash evaporation.

The flow path of the kneaded material from the tip of the barrel to the cooling device is gradually narrowed, and the flow path of the cooling device is annular. As a result, the kneaded material could not flow smoothly into the cooling device, causing the kneaded material to stagnate in the barrel, making it impossible to produce a uniform product, and causing problems such as excessive pressure being applied to various parts of the device. Especially with a 2-axis extruder,
Since there are two flow paths for the kneaded material in the barrel, this problem is serious.
さらに、内側冷却部は外側冷却部の内部にあ
