I. Introduction of Soybean Chunks/Nuggets/Badi

Soybean chunks, also known as soya badi or soy meat, is a textured vegetable protein (TVP). Textured soy protein uses cold-pressed soybean meal as the main raw material, supplemented with gluten powder. The material then undergoes textural changes under the specific pressure, temperature and shear of the twin-screw extruder, and expands into a spongy extrudate with certain strength and toughness. The extrudate contains high protein and can be used as a raw material for various snack foods and prepared dishes.

IV. The Flow Chart for Making Soybean Chunks/Badi 

• Step 1: Crushing
• Step 2: Mixing
• Step 3: Extruding& cutting
• Step 4: Drying (to reduce the water content to 8%)
• Step 5: Seasoning(optional, it’s to produce flavoured textured veggie protein)
• Step 6: Cooling before packing
• Step 7: Packing

Soyabean chunks making machine working details :

1)The mixer mixes the dry powder (soybean meal, gluten powder) evenly. 2) Textured soy protein can be produced in a standard twin screw extruder. The soybean meal and wheat dry powder mixture was fed at a constant rate while raw water was added to the extruder. The water content should be less than 50%. 3) Set heating and cooling zones temperature, screw speed, pressure, etc., and the extrusion process starts. Due to the rapid temperature and pressure changes in the extrusion cavity, the food product tends to expand rapidly as it exits the die, creating crunchy texture. 4) The protein puffs are transferred to the drying oven. The ovens are designed as single or multiple layers depending on the throughput and final moisture content requirements. By setting the drying temperature and time, semi-finished soybean TVP is finally obtained. 5) According to market demand, soybean textured protein can also be seasoned according to people’s taste preference, such as chicken flavor, pork flavor, beef flavor, etc. This can be realized either via adding chicken/pork/beef powders into the recipes before extrusion or coating the seasoning powder before packing.

Flexibility

• Different formulations:The texrured soy protein fibrous structure quality is largely effected by the extrusion parameters, including temperature, moisture, feed rate, barrel temperature, shear, pressure & temperature at die and other mechanical properties. Therefore, by adjusting all these extrusion parameters of the soyabean chunks/abi making machine, different formulations can be flexibly realized. The operation is convenient, the texture is uniform and continuous production is possible.
• Multi material: The twin-screw extrusion process is applicable to a wide range of raw materials, including peanut protein powder, wheat protein powder, and pea protein powder, so as to produce various TVP; Other raw materials, such as starch can be supplemented to optimize the strength, elasticity and fibrosis of TVP.
• Shapes: By changing different extrusion dies, you can produce soya TVP in various shapes, such as soya chunks/nuggets/badi, flakes, strips, balls, pellets, etc. Dayi provides custom mold service.
• Laboratory extrusion customization service: If you pay attention to formula innovation and new product development, we recommend that you have a micro laboratory extruder for testing and adjusting the new formulations.
