About the Agrinex Pneumatic Sheller (Vibrosheller)
Efficiently separates the husk from paddy grains using controlled vibration, minimising grain breakage and maximising shelling recovery.
The Agrinex Pneumatic Sheller — commonly known as the Vibrosheller — is the heart of the paddy dehusking process in any rice milling line. Using a pair of high-precision counter-rotating rubber rolls with a precisely controlled adjustable gap, the Pneumatic Sheller removes the husk from paddy grain with minimal force — delivering the critical combination of high shelling efficiency and low grain breakage that determines the head rice yield of the entire mill.
Variable speed control allows operators to fine-tune roll pressure to suit different paddy varieties, moisture levels, and grain sizes. The energy-efficient motor drive, low noise levels, and easy rubber roll replacement make the Agrinex Pneumatic Sheller one of the most practical and cost-effective dehusking solutions available for Indian rice millers. The machine is available in two capacity ranges to suit both medium and large commercial milling operations.

Who Uses This Machine?
The primary dehusking machine in any rice milling line — positioned between the pre-cleaning stage and the paddy separator/husk aspirator.
Frequently Asked Questions
1: How does the Agrinex Pneumatic Sheller minimise grain breakage?
A: It uses precisely controlled counter-rotating rubber rolls with adjustable gap and variable speed, ensuring only the minimum force necessary is applied to remove the husk, preserving grain integrity.
2: How often do the rubber rolls need to be replaced?
A: Roll replacement frequency depends on throughput volume and paddy variety. The quick-change design minimises downtime when replacement is needed.
