Shijiazhuang Xinlu Technology Co., Ltd. - Comprehensive Technical Overview of Soyabeans Processing Plant

A soyabeans processing plant represents a significant industrial operation designed to transform raw soybeans into various valuable products including edible oil, animal feed ingredients, and human food products. The engineering of such a plant requires careful consideration of process flow, capacity planning, and product diversification. At Shijiazhuang Xinlu Technology Co., Ltd., we approach plant design with a focus on operational efficiency, product quality control, and adaptability to market demands.

The processing sequence begins with raw material handling systems. These include receiving pits, conveyor systems, and initial cleaning equipment designed to remove foreign materials such as stones, stalks, and metal fragments. The cleaning section typically employs vibrating screens, destoners, and magnetic separators to ensure only clean soybeans proceed to subsequent stages. Proper raw material handling is crucial for protecting processing equipment and maintaining final product quality.

The core processing stages include conditioning, dehulling, and preparation. Conditioning involves adjusting the moisture content and temperature of beans through steam treatment, which facilitates optimal processing characteristics. Dehulling systems utilize impact or roller mills to crack the beans and separate the hulls through aspiration and screening. This step is particularly important for producing high-protein meal products, as removing the fibrous hulls increases the protein concentration in the final meal.

The flaking process follows preparation, where conditioned bean meats are passed through heavy-duty flaking rolls to create thin, uniform flakes. This mechanical action disrupts the cellular structure of the beans, creating greater surface area for efficient oil extraction. The flaking process parameters must be carefully controlled to achieve optimal flake thickness and integrity, which directly impacts extraction efficiency.

Oil extraction represents a central component of the processing plant. Two primary methods are employed: mechanical pressing and solvent extraction. For large-scale operations, solvent extraction using food-grade hexane is commonly implemented due to its high extraction efficiency. This system includes an extractor where solvent percolates through the flake bed, miscella distillation for solvent recovery from the oil, and a desolventizer-toaster (DT) for removing solvent from the defatted flakes while simultaneously cooking them to improve nutritional quality.

The downstream processing of extracted materials involves multiple pathways. Crude soybean oil undergoes refining processes including degumming, neutralization, bleaching, and deodorization to produce edible-grade oil. The defatted flakes can be processed into various products: they may be ground into soybean meal for animal feed, or further processed to create soy protein concentrate, isolate, or textured vegetable protein through additional extraction, precipitation, and drying operations.

Modern soybean processing plants incorporate sophisticated control systems to monitor and optimize process parameters. Programmable Logic Controllers (PLC) and Supervisory Control and Data Acquisition (SCADA) systems enable operators to maintain consistent product quality while maximizing production efficiency. The plant design also includes utilities such as boiler systems for steam generation, water treatment facilities, and environmental controls for air and water emissions.
