Blow-off system Cerex

Overview
Our puffing technology expands grains while preserving shape, improving texture and nutritional properties. The system delivers high production yield with reduced energy consumption and is engineered for industrial hygienic operation to meet stringent food-safety requirements.

Key benefits

• High yield – Production yield up to 95%, reducing waste and ensuring uniform puffing.
• Hygienic industrial design – Fully sealed expansion channel and hygienic construction to prevent contamination.
• Lower energy use – Typical energy consumption around 60 kWh per 100 kg (vs ~120 kWh for some alternative industrial systems).
• Reduced noise – Reactor-based system instead of puffing guns, lowering noise emissions in production areas.

Key features

• Fluidized preheating – Uniform conditioning of each grain prior to expansion to optimize yield and reduce energy loss.
• Controlled laminar expansion – Laminar flow from the hydrothermal processing unit to the expansion channel for consistent expansion and minimal unpuffed grains.
• Steam-reactor expansion – Overheated steam pressurizes the reactor; sudden pressure release vaporizes internal moisture, producing volume increase (up to ~12x depending on raw material).
• Sealed expansion channel (drum) – Example drum ~8 m for product finishing, energy dissipation and gravity discharge.

Plant operation & configuration

• Control system – Intuitive touchscreen interface, integrated safety circuits with automatic stops, and data-logging for traceability.
• Modular configurations – Single: 350–500 kg/h; Double: 700–1000 kg/h; Quattro: 1400–2000 kg/h.
