Ensuring the Steam Requirement of the Rice Mills

Steam Boiler for Rice Mills

Boilers are an essential part of the rice milling industry, whether you know it or not. If you’re talking about Parboiled Rice, Steamed Rice, Paddy Drying, or other Rice milling processes, much of the manufacturing process involves the use of steam or hot water created by industrial boilers. As a result, selecting a boiler system for a Rice Mill should be done with caution. Let’s take a closer look at how steam boilers lead to Rice milling’s performance.

Parboiling In Rice Milling

Parboiling process involves the hydrothermal treatment of paddy before milling. The advantage of the parboiling process stems from the gelatinization of rice starch and hardening of rice kernel that it brings about. As a result, breakage losses during milling of rice can be minimized. Five major steps in the parboiling process are required, as follows

Soaking paddy in water (cold or lukewarm water) to increase the moisture content.
Steaming paddy to achieve partial gelatinization.
Drying paddy to save the moisture content for storage and milling.
Husking to remove paddy husk from paddy kernel.
Milling to remove bran from brown kernel.
