Production steps of soy milk production line

For large-scale soybean pulp production, opting for a soybean milk production line enhances efficiency, improves the qualification rate of soybean pulp, and reduces labor costs. The process involves several key steps:

1. **Bean Preparation**: Dry soybeans or black beans are roasted at 200–250°C for 15–20 minutes, then peeled to achieve a peeling rate above 70%.

2. **Soaking**: Beans are soaked in water at a temperature not exceeding 35°C for 3–4 hours in summer or 6–14 hours in winter.

3. **Washing and Storage**: Soaked beans are washed to remove impurities and stored in a storage tank.

4. **Refining**: The beans are refined to a consistency of 10–13°C using a refining machine.

5. **Boiling**: The soy milk is boiled, ensuring the outlet temperature exceeds 100°C.

6. **Homogenization and Refinement**: The degassed soy milk is finely refined.

7. **Sterilization**: The milk is sterilized at 135–139°C for 4–6 seconds.

8. **Cooling and Packaging**: The milk is cooled and filled into containers.

This streamlined process, supported by equipment like stainless steel containers, double-layer kettles, and colloid mills, ensures high-quality soybean pulp production while optimizing resources and labor.
