100TPD Soy Protein Isolates Production Line Project Report

The 100TPD Soy Protein Isolate Production Project undertaken by ABC Machinery is mainly designed with 5 main production sections. The raw material is Non-GMO soybean material and its annual capacity can be up to produce 6,500 tons of SPI.

  • Soybean Pretreatment & Dehulling Section: 100 tons per day
  • Low-temperature Solvent Extraction Section: 80 tons per day
  • Dietary Fiber (food-grade) Processing Section: 10 tons per day
  • Water Treatment Section: 50 tons per hour
  • Boiler: 2 tons, 4 tons and 20 tons

This design of this soy protein isolate production project makes use of the alkali dissolution and acid precipitation to separate the fiber and protein in the low-temperature soybean meal. This protein content in the final soy protein isolate is high by this technology. But, it should be equipped with water treatment facility to ensure water consumption.
