Parboiling is a hydrothermal process that involves the steps of soaking, gelatinization, and drying before the grains are hulled. Inefficiency in any of these stages can reduce the benefits of the process and the nutritional value of parboiled rice. Precise grain flow management is essential to ensure process integrity.

The Garten Gate Valve was developed to optimize flow control in the processing line. Its advanced engineering prevents grain accumulation between articulated parts, ensuring smooth and continuous processing.

The Pneumatic On/Off model, with a cylindrical design, is the ideal solution for regulating rice discharge during the soaking stage, ensuring effective handling of parboiling tanks.
