Device for puffing snack and system for producing puffed snack food

摘要

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.

主权项

1. A device for puffing snacks for producing puffed snack foods comprising two opposing, cylindrical rollers, which are heated by the device and between which ingredients are compressed and, in turn, become puffed, wherein: the two cylindrical rollers each define a sealed space fed by a supply passage and emptied by an outlet passage; the two cylindrical rollers each also define at least one peephole for visually inspecting the sealed space; a suction pipe for removing water that collects in the sealed space, the suction pipe being mounted on a moveable body to maintain a substantially constant position where the water collects; and, the two opposing, cylindrical rollers are heated by hot steam fed into the sealed space through the supply passage that creates relatively higher pressure in the sealed space that creates suction in the suction pipe.
