Parboiling is a hydrothermal process used in rice processing that involves partially boiling paddy before milling. This process helps in gelatinizing the starch, improving grain strength, and enhancing nutritional value.

Main Steps in Parboiling:

Soaking:
Paddy is soaked in water at controlled temperature for a specific duration. This allows moisture to penetrate the grain and initiates starch gelatinization.
Steaming:
The soaked paddy is then steamed under controlled pressure. This step completes the gelatinization process, strengthens the grain structure, and helps seal internal cracks.
Drying (Final Step):
After steaming, the paddy is dried to reduce moisture content to a level suitable for milling. Proper drying is critical to maintain grain quality and avoid breakage during milling.

Types of Parboiling

Single Stage Parboiling:
In this method, soaking and steaming are carried out in a single cycle. The paddy is soaked to achieve the required moisture level and then directly steamed. This process is simple, cost-effective, and suitable for standard quality rice production.
Double Stage Parboiling:
In this method, the process involves two cycles of soaking and/or steaming. The paddy undergoes an initial soaking and steaming, followed by a second stage to ensure deeper starch gelatinization and uniform moisture distribution. This results in stronger grains, better milling yield, and improved rice quality.

Parboiling Capacity by “SHINER”

“SHINER” offers parboiling solutions with a wide processing capacity ranging from 4 tonnes to 60 tonnes per batch.

These systems are designed to meet the requirements of small, medium, and large-scale rice mills, ensuring efficiency, uniform processing, and high-quality output.

SUNCUE MultiGrain Dryer

Drying:
After steaming, the grains are dried to reduce moisture content to a safe level for storage and further processing. Controlled drying ensures uniform moisture removal, prevents fungal growth, and maintains grain quality.

This drying process not only minimizes grain breakage during milling but also helps in preserving the nutritional profile by retaining essential water-soluble nutrients and minerals. Parboiling, followed by efficient drying, is widely practiced across South Asia and Southeast Asia, playing a crucial role in global rice production.
