Vertical rice whitening machine TopWhite™ BSPB

abrasive

Overview
The TopWhite BSPB is a vertical rice whitener designed for gentle whitening with high head‑rice yield. It operates on a top‑to‑bottom abrasive principle and integrates cool‑air aspiration and dedusting to reduce broken rice and support food safety.

Key benefits

• Easy access and maintenance: wide doors provide full access to the milling chamber for rapid screen changes and inspections.
• Reduced residue buildup: efficient aspiration and bran discharge keep the whitening chamber clean.
• Lower downtime: adjustments can be made during operation; three brakes can be set simultaneously from a central control panel.

Highlight features

• Aspiration & cooling: cool‑air flow minimizes grain fragility and breakage while dedusting conveys bran out of the whitening chamber.
• Processing layout: two top inlets feed rice into the chamber via a feed screw; whitening takes place between abrasive rings and a screen.
• Adjustments: handwheel for coarse gap changes between rotor and brakes; balancing weight for fine tuning of the retaining gate.

Controls
Settings are adjustable during operation for quick process tuning. Coarse adjustments use the handwheel; fine adjustments are achieved with the balancing weight. Central panel control allows simultaneous brake settings to standardize performance.

Higher yields
The vertical abrasive principle with multiple abrasive rings (typically six) and a screen is optimised to remove bran while preserving whole grain, producing high head‑rice yields for milling operations.
