Automatic Rice Washer – Pressure Cleaning System

This model is an automatic rice washer that uses natural water pressure to clean the grains efficiently, eliminating the need for manual scrubbing. Its internal structure features a channel system that harnesses the upward flow created by water pressure, loosening starch, dust, and small impurities from the rice.

The washing chamber includes small, carefully designed slits that allow water to circulate freely while preventing rice grains from getting stuck or clogging the system. These fine openings ensure a smooth, continuous flow and help expel debris without blocking the water path.

To use it, simply place the rice inside the perforated chamber, turn on the faucet, and let the water pressure do the work. Water enters from the bottom, moves through the main conduit, and pushes impurities upward and out, creating a continuous and effective cleaning cycle.

The design is optimized for functional 3D printing, featuring reinforced walls, evenly distributed openings, and rounded edges for safe and comfortable handling. With no moving parts, it is easy to wash, durable, and ideal for daily use in the kitchen.

Perfect for anyone looking for a practical, hygienic, and hands-free way to wash rice or other small grains.
