Cassman has successfully completed final quality inspection, export packaging, and shipment of a 1000L/h HTST Flash Pasteurizer to a craft brewery in Belgium. Designed specifically for premium beer applications, the system enables the customer to achieve microbiological stability and extended shelf life—without compromising the fresh, aromatic character that defines their brand.
The Belgian brewery sought a pasteurization solution that could:
Preserve delicate flavor and aroma—maintaining original pH, color, bitterness (IBU), and volatile esters.
Replace energy-intensive tunnel pasteurization with a more efficient, lower-loss alternative.
Automate critical process parameters (temperature, flow rate, holding time) to ensure batch-to-batch consistency and full traceability.
After evaluating multiple suppliers, the brewery selected Cassman for its beer-specific HTST expertise and integrated engineering approach:
Optimized thermal profile: Rapid heating to 72°C, 30-second hold, then immediate cooling to 2–4°C—delivering ~25 Pasteurization Units (PU) while minimizing thermal stress on the beer.
Energy recovery via plate heat exchanger: Multi-stage heat exchange uses outgoing hot beer to pre-heat incoming cold beer, cutting steam consumption by up to 80% compared to tunnel systems.
Full sanitary design: All product-contact surfaces in SUS304 stainless steel, with CIP-ready valve logic and seamless cleaning integration.
Reliable automation: Controlled by a Siemens S7-200 PLC and Smart 1000 HMI, featuring automatic temperature regulation, flow monitoring, and safety interlocks. Sub-spec product is automatically diverted to a buffer tank for reprocessing—ensuring zero compromised batches reach packaging.
Premium components: Includes Southern (Nanfang) pumps, AirTAC pneumatic valves, Spirax Sarco steam controls, ColliHigh sensors, Daniel plate heat exchangers, and CHNT electrical systems—all selected for durability and serviceability in brewery environments.
Model: Cassman HTST-1000
Capacity: 1,000 L/h
Temperature profile: Inlet 2°C → Pasteurization 72°C (±0.5°C) → Outlet 2–4°C
Holding time: 30 seconds (~25 PU)
Utilities: 380V/50Hz/3-phase, ~2 kW; 0.4 MPa steam; 0.5 MPa compressed air
Heat exchange area: ~5 m² (SUS304 plates)
Control & safety: Siemens PLC/HMI with real-time alarms, data logging, and automatic reflux on temperature deviation
Benefit | HTST Flash (Cassman) | Traditional Tunnel |
Flavor preservation | ✅ Minimal impact on pH, color, IBU, aroma | ❌ Prolonged heat exposure degrades volatiles |
CO₂ & foam stability | ✅ Better retention due to shorter exposure | ❌ CO₂ loss and foam degradation common |
Energy use | ✅ Up to 80% less steam via heat recovery | ❌ High steam and cooling demand |
Product loss | ✅ 5–10% lower beer/water waste | ❌ Significant loss during start-up/shutdown |
Footprint | ✅ Compact, skid-mounted, easy to integrate | ❌ Large tunnel chamber requires dedicated space |
The system was configured to interface directly with the customer’s bright beer tank (BBT) and downstream packaging line, using standard sanitary tri-clamp connections.
CIP compatibility: Pre-programmed cleaning sequences allow quick switch between production and cleaning modes.
FAT completed: Full Factory Acceptance Test conducted before shipment, including P&IDs, wiring diagrams, SOPs, and PU validation guidelines.
Commissioning support: Cassman provides remote start-up assistance, with optional on-site technician for operator training and performance verification.
Extended shelf life for domestic and EU export markets—without flavor compromise.
Lower operating costs through reduced steam, water, and product loss.
Auditable, repeatable pasteurization with automated quality safeguards.
Enhanced consumer experience via consistent foam, carbonation, and aromatic profile.
“We brew traditional Belgian styles where nuance matters—esters, phenols, hop aroma. Tunnel pasteurization was eroding that character. With Cassman’s HTST flash system, we now pasteurize at 1,000 L/h with precise control and automatic safety reflux. Every batch meets spec, and the beer tastes like it should—fresh, vibrant, and true to our recipe.”
