In the production of fermented soybean meal, fermented rapeseed meal, and fermented cottonseed meal, a complete fermentation process requires the coordination of multiple subsystems. Ocean's fermentation solutions cover the entire process from strain activation to finished product packaging.

I. Strain Propagation and Hot Water Supply System

Strains are manually added into the activation tank, where the activation process takes approximately 72 hours. The system automatically controls pH value, agitation, aeration, and temperature regulation. After activation, the strain liquid is transferred to a metering scale for standby. The hot water tank heats and regulates tap water according to process requirements, which then enters a hot water metering scale.

II. Strain Fermentation System

Based on fermentation parameters, the metered strain liquid and hot water are proportioned according to the formulation and thoroughly mixed in a mixer. The mixed strain fermentation material is then transported by an automatic rail car system to the strain fermenter for approximately 12 hours of strain propagation fermentation.

III. Soybean Meal Batching, Mixing, and Fermentation System

Raw soybean meal enters a storage bin through the feed inlet, is elevated to a batching scale by a bucket elevator, and is metered before entering the mixer. The fermented strain is discharged from the strain fermenter, conveyed via belt conveyor and a specialized wet-material bucket elevator to a strain loss-in-weight scale, and then enters the mixer according to formulation requirements. At the same time, the proportioned hot water also enters the mixer. After mixing, the material is sent to the fermenter by the automatic rail car system for approximately 24 hours of deep soybean meal fermentation.

IV. Drying, Cooling, Grinding, and Packaging System

After fermentation is complete, the material is discharged from the bottom of the fermenter and conveyed by belt conveyor to the drying system. The fermented material enters the dryer at a constant speed via a variable-frequency, constant-speed discharge device. After drying, pulse dust collection, spray sedimentation, and screening, the material is conveyed by air to a cooler for cooling. The cooled finished product is elevated to a holding bin for grinding, then enters a grinder. After grinding, the product is conveyed by air to a vibrating screen for classification, finally entering a finished product bin before being packaged by the packaging system.
