Corn Puffing Snack Machine Makes Corn More Possible

Corn puffed snack uses corn flour, oats, and other grains as raw materials, which are extruded and ripened by screw and shaped. The shape can be realized by changing the mold, including ball, tube, heart, slice, and so on, different flavors can be obtained by seasoning.

Ingredients: corn flour, rice flour, flour, other cereal ingredients, etc.

Products: we can by changing the mold to get different shapes, such as heart-shaped, spherical, pentagram, tubular, ring-shaped, etc.

The puffed corn snack machine is composed of a feeding system, extrusion system, rotary cutting system, heating system, transmission system, and control system. Puffed corn snack machine adopting advanced screw extrusion technology, materials are matured and expanded by high temperature and high pressure, which can be completed simultaneously. The main engine takes frequency control to ensure the stability of the production process. The products are of various colors, varieties, beautiful appearance, natural, lifelike, delicate texture, and widely used raw materials.

Expanded corn snack production line

Working principle:

Extrusion and propulsion using the extruder’s pressure ring and screw system removes gases from the material and is rapidly filled by the material. The material undergoes the shearing force’s action and generates backflow, which increases the pressure in the chamber. With the friction between the screw and the chamber, the material is fully mixed, extruded, heated, glued, and gelatinized, and the original structure is damaged. At the same time, the machine can be transformed into heat energy through the friction of materials in the bore, making the materials become a gelled state with flowing properties. When the materials are squeezed to the outlet, the pressure changes from high pressure to normal pressure, from high temperature to normal temperature, causing the water to evaporate from the organizational structure rapidly, forming numerous microporous structures inside. Then, through the cutting device, the cutting is cooled. Namely, the expansion is formed.


Series of extruder

Equipment features:

1. The expander adopts the advanced technology of frequency converter to adjust the speed, making the equipment more powerful, more stable, and more energy saving.

2. The screw has a long service life. Some extruders adopt building block structure, which can be combined arbitrarily according to different needs.

3. The automatic lubrication system reduces mechanical energy consumption and prolongs service life.

4. The visual automatic temperature control system makes temperature control more intuitive and parameters more clear.

5. The screw has the function of self-cleaning and does not need to be disassembled for cleaning.

6. Different screw and length diameter ratio can meet different production processes.

7. Recycling, drying, oil spraying, cooling, fully automatic one-time completion, greatly reduces the labor intensity of workers, makes products cleaner and sanitary, and greatly improves work efficiency.

Molds of different shapes

Actual production

Production process:

The raw materials are added to the extruder. After a series of processes, all the raw materials are mixed and then cooked. Huge pressure is exerted on the other end of the equipment. At this time, the extruder is like a huge pressure cooker. The screw carries the raw materials from one end to the other in the interior. In this process, the raw materials are cooked, mixed into a paste, and squeezed with huge pressure. Through the precise mold, the final shape of the snack is formed. The raw material will be squeezed through a small mold hole. When it contacts the air, it will keep its shape and expand rapidly. When the snack is extruded from the die, a set of blades rotate at high speed of 16 revolutions per second, cutting the snack into its final shape.

Corn puffed food of different shapes

The food produced by the extruder is rich in nutrition, easy to eat, and easy to store, which provides a set of feasible new standards for the commodity transformation of a large number of agricultural products, thus opening up a new way to solve the difficulty of agricultural products sales.
