I. Introduction of Fried Shell Snack

The fried shells are made of wheat flour supplemented with cornstarch. It is made by the extrusion snacks food machinery.

1) Grain flour and other ingredients (such as vegetable oil) are mixed in a certain proportion and added to the extruder at a constant speed. 2) The grain dough is extruded from the specially designed die into a curly shape, like a shell. The shell-shaped part is cut off by the rotating blade at a certain fast speed and enters the next process. 3) The semi-finished shells are fried by batches in the batch-fryer. The batch frying machine is equipped with a vibration deoiler to reduce the residual oil on the shells. 4) Finally, the production is completed through the seasoning process and packing process.

VI. More

Flexibility:

• Twin screw extrusion technology is suitable for a wide range of grain raw materials. Multi-grain blends or single grains can be processed to extrude the shells with different nutritional content and taste.
• Extrusion dies can be replaced to produce shells of different shapes and sizes, such as snail shells snack, conch shells snack; large shells snack, small shells snack, etc.; the thickness and threads-pattern on the shells can also be changed flexibly.

Innovation Potential

With minor adjustments, this fried shell snack food processing machinery can also enable the production of other various fried extruded food recipes, for example:

• Replace the shell shaping die with spiral/stick/octopus shaping dies to realize the formulas-production of spiral/stick/octopus snacks.
• Replace the shell extrusion die with a strip extrusion die, and add a cone molding machine, this snack food machinery can realize the formula production of bugles/cone chips;
• Replace the shell extrusion die with a strip extrusion die, and add a roller forming machine, this snacks machinery can produce fried doritos/triangle corn chips.
