I. Introduction of Colorful Cereal Loops

The raw materials of colorful cereal loops are two or several kinds of grain flours combination (corn flour, wheat flour, rice flour, oat flour, black rice flour, etc.), and some are supplemented with vegetable powder such as pumpkin powder, spinach powder, etc., to achieve multiple nutritional purpose. Extrusion die is specially designed.  After the grain dough is extruded from the die and cut off, the cut-off extrudate will rapidly expand into a circle shape (water vapor escaped ). The various bright colors can be obtained by adopting natural colors or safe artificial colors. Breakfast cereal loops add to the pleasure while providing nutrition.

Like all other breakfast cereals, in order to keep the puffed cereals loops soaked in milk from breaking, it is important that the cereals have a finer puff texture with smaller puffed pores, so a lower gelatinization temperature is required, so an extruder with longer barrel is required. In this way, the cereal dough is kneaded for a longer time in the extrusion barrel to achieve the desired configuration.

IV. The General Flow Colorful Breakfast Cereal Loops

• Step 1: Mixing of raw materials
• Step 2: Extruded and cut to ring shape pieces
• Step 3: Cooling
• Step 4: Pre-drying
• Step 5: Blending
• Step 6: Seasoning
• Step 7: Drying after seasoning
• Step 8: Cooling before packing
• Step 9: Packing

The specific steps to produce breakfast cereals loops with extrusion technology are as follows:

Mix the grain flours, water and other raw materials in a certain proportion, and stir evenly. The mixture is loaded into the lengthened extruder, and is kneaded into an ideal dough by setting a certain temperature and pressure. A ring-shape forming die is installed at the exist of the extruder. After the dough is extruded from the die, the rapidly rotating blade cuts off the extrudate. Due to the pressure difference, moisture escapes, and the cut extrudate rapidly expands to circle shape. Then the cereal circles are dried, baked and through other processes to make them crunchy. Up to now, the plain flavor cereal loops are done. According to market demand, the seasoning drum can be used for the seasoning process. Finally, the seasoned cereal loops are dried, cooled and packed.
