I. Introduction of Oats Rings Cereal

The raw materials of oat rings breakfast cereal are whole grain oats flour, a certain percentage of cornstarch. Compared with other cereals, oats have high nutrition for health. The protein content of oats is the highest among cereals (the protein content in natural oats is 13%~15%). Dietary fiber content is 10 times that of rice. Unsaturated fatty acids are 5 times that of rice. Oat-based cereal rings can supplement the body’s needs with other breakfast cereals. Along the growing interests in health claims, oatmeal-based breakfast cereals are gaining traction.

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

Besides, due to the high oil content of oats, a higher cooking energy input is required. Plus, oats are high in fiber, it doesn’t expand well. Therefore, we suggest adding a pre-conditioning process beforeextrusion process to gelatinize the oat starch in advance.

V. The General Flow Chart for Oat Rings Cereal Food Processing

• Step 1: Mixing of raw materials
• Step 2: Pre-conditioning (pregelatinization for oat)
• Step 3: Extrusion of oats cereals and ring shape forming
• Step 4: Cooling
• Step 5: Pre-drying
• Step 6: Seasoning
• Step 7: Drying after seasoning
• Step 8: Cooling before packing
• Step 9: Packing

Work steps with the fully automatic breakfast cereal food processing machines:

1. Mix the whole grain oat flour, corn starch, water and other raw materials in a certain proportion, and stir evenly.
2. The mixture is loaded into the pre-conditioner to have the pregelatinization.
3. Then the pregelatinized oat dough is conveyed from the pre-conditioner to a extruder with lengthened barrel. The dough is kneaded into an ideal configuration by setting a certain temperature and pressure. A ring-shape forming die is installed at the front of theextruder machine. 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.
4. Then the cereal circles are dried, baked and through other processes to make them crunchy. Up to now, the plain flavor oat rings are done.
5. According to market demand, the seasoning drum can be used for coating honey.
6. Finally, the honey flavoroat rings are dried, cooled and packed.
