High-Performance Unit Type Whitener for Short Grain

Maximizing Rice Milling Plant Profitability

We sometimes receive inquiries from customers who are disappointed that their rice milling recovery rate and operational efficiency have not improved as expected even after installing sophisticated rice milling equipment.

First, you need to find out which part of the rice milling process is the bottleneck. Often the equipment is not connected correctly, or there is a mix of products from multiple companies on the rice milling line, resulting in a large amount of broken rice.

To maximize profits, the entire operation must be designed scientifically, considering the rice’s character and the processing conditions. This planning should be completed before installing any equipment. However, it requires many years of experience and deep expertise.

Building on our many years of experience providing a wide range of equipment for rice milling, we can offer comprehensive plant optimization consulting, including the following.

  • Rice milling plant design.
  • Suggestions for minimizing running costs and improving maintenance efficiency.
  • Offering ways to improve operational efficiency with digital technology.
  • Advice on how to improve an existing plant’s ability to meet market trends.
  • Advice from rice milling professionals.

Also, assembling a unified rice milling line with our equipment will enable high-quality rice production with a high yield while minimizing power and labor costs.

If you are thinking of building or reviewing a rice milling plant, don’t hesitate to contact us.

Best Practices for Productivity and Quality Improvement
Sun Drying

Without proper drying, the rice will crack during the drying process. In such a case, no matter how much effort is put into the rice mill, the milling recovery rate will not increase.

Our Solution

The best way to achieve higher quality rice, higher milling recovery rates, lower costs, and stable production is to own and manage the drying and milling machines.

We are one of the few manufacturers with expertise in both drying and milling rice. Let us support the growth of your rice production business with our machines.

Whitener and Polisher: Integrated Unit or Tandem Configuration?
Yamamoto’s unit type whitener NX-5000

When comparing the integrated type with the tandem configuration, several key differences should be considered:

  • The integrated unit requires less installation space, making it a more space-efficient option.
  • In a tandem configuration, each machine needs to be started, stopped, and adjusted individually. However, with an integrated unit, these actions can be performed by a single switch, and the use of current value control enables hands-free operation, which is another significant advantage.
In the catalog, is the capacity listed for inputting brown rice or outputting white rice?

The machine's capacity is listed by inputting brown rice, which may differ based on the material used.
