Device for puffing snack and system for producing puffed snack food

Abstract

This invention is a device for puffing snacks and a system for producing puffed snack foods. This invention makes it possible to overcome wiring problems, reduce heating costs of equipment for heat-pressing the ingredients of puffed snack foods, and expand the scale of the device, thereby increasing production efficiency. Pellets of ingredients are transported along a conveyor belt (14) through a hot water tank (13) where they are blanched. Next, the pellets are taken out of the hot water and moved underneath heaters (15). After being dried by the heater, the pellets are fed between rollers (21, 22) in prescribed portions within a prescribed time. The pellets are heat-compressed by the rollers (21, 22) and puffed. The space in the rollers (21, 22) is filled with hot steam so that the surface is uniformly heated.
