Description

Technical Field

[0001] The utility model relates to the technical field of puffed food processing, in particular to a filling machine for puffed food processing. Background Art

[0002] Puffed food is also known as extruded food, exploded food, and light food abroad. It uses cereals, potatoes, beans, etc. with low moisture content as the main raw materials. After pressurization and heating, the volume of the raw materials themselves expands, and the internal structure also changes. After processing and molding, the food is made. Due to the porous and fluffy structure of this type of food, it tastes crispy and sweet, has certain nutritional value, and is very popular among children. However, to preserve puffed food, it is necessary to fill the bag with inert gas to keep it fresh, so a puffed food filling machine is needed.

[0003] Prior art Chinese patent publication CN207174066U discloses a filling machine for puffed food processing. The machine comprises a fixed plate with one or more fixed sleeves extending through the middle of the plate. The sleeves have a fixed shaft hole in the middle, through which an air inlet pipe is disposed. One end of the air inlet pipe is connected to an aeration head, and the other end is connected to an inert gas delivery device. The aeration head has a first inclined surface on its upper and lower ends, respectively. Two hinged rotating rods are provided on the upper and lower ends of the fixed plate. A pressing plate is positioned between the two rotating rods. A second inclined surface is provided on the lower end of the pressing plate, facing the first inclined surface. A heating mechanism is provided in the middle of the pressing plate. When the pressing plate is pressed downward, the second inclined surface presses the aeration head with the first inclined surface outward. While this device can fill and seal packaging bags with gas, it requires manually controlling the two pressing plates to move closer together to heat and seal the bags. Furthermore, the bags must be manually replaced after each sealing operation, increasing worker workload, consuming time and effort, and resulting in low production efficiency.
