1. Complete Rice Milling Equipment Process Flow

Modern rice milling equipment follows a continuous and integrated processing line, including the following key stages:

1.1 Pre-Cleaning (Impurity Removal)

Purpose:

Remove impurities such as:

Dust

Straw

Metal particles

✔ Protect downstream equipment

✔ Improve processing efficiency

1.2 Stone Removal (Destoning)

Using a clean and destoner machine, heavy impurities like stones are removed.

Benefits:

• Prevent machine damage
• Improve rice purity
• Ensure stable operation

1.3 Paddy Hulling

• Removes husk from paddy
• Produces brown rice

✔ High hulling efficiency
✔ Low broken rice

1.4 Paddy Separation

Separates:

• Brown rice
• Unhulled paddy

✔ Improves milling efficiency
✔ Reduces reprocessing load

1.5 Rice Whitening

Removes the bran layer

Produces white rice

✔ Controls milling degree
✔ Ensures smooth surface

1.6 Bran Crushing & By-Product Handling

• Processes rice bran
• Maximizes by-product utilization

1.7 Rice Grading & Screening

• Separates head rice and broken rice
• Ensures uniform product quality

All processes work together in a centralized system, ensuring high efficiency and low energy consumption.
