Cashew Kernel Humidification System

Dried kernels are too brittle to peel cleanly straight away. LOCUS ultrasonic humidifiers bring moisture back up just enough to loosen the testa skin from the kernel — without over-wetting it — so the peeling stage can lift it off without breaking kernels.

Why Ultrasonic Humidification

Just enough moisture to loosen the testa

Too little moisture and the testa won't separate cleanly; too much and kernels come out soft and prone to breaking. Ultrasonic humidification with forced air gives fine enough control to hit the same target window on every batch.

Ultrasonic humidification brings kernels to a target 3.5–4.5% moisture over 5–12 hours
Forced air circulation spreads moisture evenly through the batch instead of concentrating it at the surface
Control panel sets target humidity and cycle time directly, so every batch reaches the same moisture window
Batch sizes from 200 kg to 1,500 kg, running on 3–6 HP motors depending on model
Consistent humidification is what allows the peeling stage to use compressed air instead of rotating brushes
Humidified kernels move directly to the peeling system at 3.5–4% moisture

Machine Architecture

What's inside a LOCUS humidification unit?

An ultrasonic humidifier and forced-air chamber, dialled in through the control panel to hit the same moisture target every cycle.

Ultrasonic humidifier

Ultrasonic misting generates fine water particles that penetrate the batch evenly, avoiding surface-only wetting.

Forced air circulation

Air movement carries humidity through the whole chamber, keeping kernel-to-kernel moisture consistent.

Direct control panel setpoints

Target humidity and cycle time are set directly on the panel — no manual sampling needed to judge when a batch is ready.

3–6 HP by model

Motor power scales with chamber size across the 200–1,500 kg batch range.

5–12 hour cycle

Cycle time varies with batch size and incoming kernel condition from the dryer.

Direct feed to peeling

Kernels leave humidification at 3.5–4% moisture, exactly the window the air-jet peeling drum is tuned for.

Process

How kernel humidification works

1
Dried kernels are loaded into the humidification chamber straight from the kernel dryer.
2
The control panel is set to the target 3.5–4.5% moisture and matching cycle time for the batch.
3
Ultrasonic misting and forced air bring the batch to target moisture evenly over 5–12 hours, loosening the testa.
4
Humidified kernels move directly to the peeling system while still within the target moisture window.
