[0044] Working Principle: After the soybean meal undergoes a cooking process in microwave treatment unit 1, its internal proteins and fats are effectively released. Simultaneously, microwave technology stimulates the aroma components in the soybean meal, enhancing its flavor. The microwave-treated soybean meal then enters an airflow pulverizer, where it is pulverized into fine particles under strong airflow, facilitating subsequent mixing and extraction. The pulverized soybean meal is then mixed evenly with other additives via a ribbon mixer, ensuring thorough integration of all materials. The mixed soybean meal enters extraction tank 404, where food-grade alkali solution and temperature control device 402 work together to help dissolve the protein from the soybean meal. A pH sensor monitors and adjusts the pH value in real time to optimize the extraction effect. The extracted liquid enters centrifugal separation unit 5, where a spiral centrifuge separates the protein from other impurities, yielding a high-concentration soybean protein solution. The separated soybean protein solution is homogenized by a multi-stage homogenizing pump to maintain solution uniformity and is stored in an insulated storage tank to prevent protein denaturation. A second centrifugal separation process further improves protein purity and removes excess water and impurities. The centrifuged liquid enters a settling tank, where sedimentation separates the solid particles from the liquid, collecting the protein suspension. The settled liquid is then sent to a neutralization reactor, where food-grade alkali is added to adjust the pH to suit subsequent processing. The soy protein is then sterilized using a high-temperature instantaneous sterilization device to ensure the final product meets food safety requirements. Finally, the sterilized soy protein enters a spray dryer to rapidly remove moisture, yielding a powdered soy protein product suitable for long-term storage and transportation.
[0045] This invention provides a production apparatus for high-soybean-flavor soy protein. Microwave treatment and airflow pulverization effectively enhance the aroma of the soy protein, resulting in a product with a rich soy flavor. Through precisely controlled extraction and centrifugal separation processes, this apparatus significantly improves the protein extraction rate, ensuring high purity of the soy protein. The collaborative operation of multiple units greatly simplifies the production process, improves production efficiency, reduces manual intervention, and lowers production costs. This invention ensures product consistency and quality stability by precisely controlling key process parameters such as temperature and pH value. High-temperature instantaneous sterilization and spray drying technologies not only guarantee product safety but also maximize the preservation of the nutritional components of the soy protein.
