I. Introduction of Instant Oat Flour

Instant oat flour, or quick oat flour, refers to precooked oatmeal made from raw or flaked oats. It is widely used in various food and beverage industries, such as instant cereal food, cereal beverages, snack foods, baking, seasoning and other food industries.  The modern extrusion process is one of the important processes for producing instant oatmeal. Extrusion equipment transforms oat flour from intimate texture to irregular, spongy texture through short-term action of high temperature, pressure and shear. The extruded oat flour has a lower gelatinization temperature, is easy to digest and absorb, has a high preservation rate of nutrients, and produces a pleasant aroma of grass, beans and nuts.

By setting the process parameters of the extrusion food process equipment, instant oat flour with different particle fineness, puffing degree or nutritional content can be realized accurately and freely. Oat can also be mixed with other grains in a certain proportion to make mixed instant grains powder.

Compared with traditional processing methods, advanced extrusion food processing plant equipment fully automates various operations such as mixing, cooking, kneading, shearing and forming. This higher cooking efficiency and more precise control significantly saves processing time and energy, improve the quality of finished products, and enrich the types of finished products.

IV. The Flow Chart of Instant Oat Flour Food Processing

• Step 1: Oat raw material screening (Optional)
• Step 2: Enzyme deactivation  (Optional)
• Step 3: Crushing into granules  (Optional)
• Step 4: Oat mixing with other ingredients
• Step 5: Pre- conditioning
• Step 6: Extrusion process (Cooking and puffing)
• Step 7: Drying
• Step 8: Crushing
• Step 9: Nutrition adding and evenly mixing
• Step 10: Measuring and packing
• Step 11: Sterilization
• Step 12: Inspection
• Step 13: Finished product

1) First cut the oat into granules, 1/2 to 1/3 the length of the whole oat. 2) Due to the high fiber content of oats, a pre-gelatinization process is required before extrusion. So there should be a twin-shaft pre conditioning machine installed above the extruder silo. 3) Once the preconditioning is done, the pre-gelatinized oat grains are transported to the twin-screw extruder, and then matured and sterilized after the desired kneading and cooking process under the correct temperature and pressure control. Due to the pressure difference between the inside and outside of the screw, the moisture of the extruded oat dough quickly turns into steam and escapes, and the oat dough expands rapidly, forming fluffy and easy-to-dissolve puffed particles. 4) Then the puffed granules goes through a drying oven to optimize the moisture content. 5) The dried oat puffs are pulverized to the required precision by a superfine pulverizer, and the production of pure oat nutrition powder is completed. 6) According to market demand, the precooked pure oat powder can be seasoned or supplemented with other nutrients through the drum seasoning machine, such as mixing with other coarse grain powder or adding micronutritions. 7)  Finally go through the packing and inspection process.

Flexibility

• According to market demand, the process parameters can be flexibly adjusted, so this food process equipment can produce a variety of oat-based nutritional powder. For example, the puffing degree of oats (low, medium, high), the degree of fineness after crushing, nutritional content, whether to mix other grains, etc., can all be realized in one production line by changing the process.

Multi-function

• By simply adding or skipping some manufacturing steps and changing the control parameters, other nutritional instant grain powder can be produced by this extrusion food processing plant equipment, such as instant rice nutritional powder, instant bran nutritional powder, instant corn powder, etc.
