Paddy Gravity Separator

Paddy Gravity Separator

Shijiazhuang Xinlu Technology Co., Ltd. presents the Paddy Gravity Separator, a purpose-built solution for rice mills and seed cleaning operations seeking to improve grain quality and reduce foreign material content. Employing gravity separation, this machine separates whole paddy grains from broken kernels, immature grains, stones, and husks, delivering a uniform product suitable for further milling or direct sale as seed.

The Paddy Gravity Separator consists of an inclined oscillating deck paired with a variable airflow system. Paddy is introduced at the feed end, where gentle vibration stratifies the mixture by density: heavier, intact grains migrate downward, exiting through the lower deck discharge, while lighter husks, bran fragments, and immature grains rise to the top and are carried away by the aspirator. Operators adjust deck stroke frequency (40–60 Hz) and airflow volume (0.4–1.5 m³/min) to accommodate differences in paddy variety, moisture level, and impurity load.

Distinctive features include:

• Dual-Zone Deck Design: Two separation zones with independently controlled stroke settings allow for coarse and fine classification in one pass.

• Precision Air Control: A multi-port plenum with flow meters provides real-time monitoring and adjustment of airflow distribution.

• Hygienic Construction: Smooth interior surfaces and access doors simplify cleaning and reduce build-up of bran residue.

• Adjustable Feed Gate: Stepless feed rate control ensures consistent deck loading and uniform separation.

• Low-Noise Operation: Vibration isolation mounts and sound-dampening panels minimize operational noise.

In operational trials at several rice mills, the Paddy Gravity Separator achieved a 30% reduction in brown rice breakage and a 20% decrease in milling energy consumption, attributed to more uniform grain size distribution and the removal of abrasive contaminants prior to milling. Enhanced removal of stones and heavy impurities also contributed to lower maintenance costs for downstream de-stoning equipment and polishers.

Routine upkeep involves checking the tension of deck mats, clearing air filters, and greasing oscillation bearings. Shijiazhuang Xinlu Technology Co., Ltd. supports clients with detailed maintenance schedules and offers extended service plans to maximize equipment uptime.

Available in capacities from 2 t/h to 15 t/h, the Paddy Gravity Separator integrates seamlessly with pre-cleaning and destoning lines. Its compact footprint, user-friendly controls, and precise separation capabilities make it a valuable asset for rice millers and seed processors focused on delivering consistent product quality and operational reliability.
