Cold-Smoking System

SORGO cold-smoking systems combine smoke, temperature, humidity and air movement in a controlled way to give the desired smoke character with uniform treatment throughout the load. They are used for salami and raw fermented sausage, dry-cured ham, bacon and individual smoked products. Like the ripening systems, the control dries the product gently and as quickly as possible without case hardening.

Process areas

Pre-ripening, ripening and cold smoking are distinct tasks and are separated technically:

• Pre-ripening / fermentation / sweating: controlled warming, fermentation, curing colour development and the start of drying; the installed air and climate capacity matches the demanding cold-smoking stage.
• Ripening / post-ripening / storage rooms: uniform drying, ripening and stabilisation over long process times with reversing alternating airflow, 2-way or 4-way climate systems and optional enthalpy-based use of outside air.
• Cold-smoking room: cold smoking with precisely controlled temperature, humidity and air movement. Friction, smouldering, wood-chip, steam or liquid smoke can be connected, with uniform smoke distribution.

Alternating airflow principle

The SORGO climate concept combines a climate conditioning unit (temperature and humidity), suction and exhaust ducts, a fresh-air duct, pressure ducts and a reversing damper that alternately distributes the recirculated air to the pressure ducts. Adjustable discs at the extraction openings set the extraction rate, and outlet nozzles in different sizes adapt air velocity and air volume to the product and room. The mixing unit is normally installed inside the treatment room but can also be placed outside; all ducts are routed to suit the room.

Heating and cooling coils

SORGO makes its own finned-tube heating and cooling coils in stainless steel 1.4301 (tubes, fins, headers and distributors), supplied with matching control valves. They deliver high capacities in a small space and are designed for CO₂, Freon/HFC, glycol, ammonia or other agreed refrigerants.

CIP cleaning (standard)

Automatic, programme-controlled CIP cleaning covers the climate conditioning unit, the air ducts, the smoke pipework and the smoke generator.

• One central cleaning station supplies several connected systems and cleans them automatically one after another.
• Detergent dosing adjustable from 1 to 10 %.
• A stainless steel booster pump delivers approx. 10 bar cleaning pressure, independent of the mains water pressure.
• Automatic fresh-water rinse after cleaning and contact time.
• The cleaning circuits reach all relevant areas, including the smoke pipework and the smoke generator.
• External distribution in stainless steel Mapress pipe; all cleaning valves are stainless steel.

Control

The system is operated with the SORGO SCS X1 control on a 15.6-inch industrial touchscreen with storable programmes and precise process control. SORGO INSPECT adds central process documentation, and remote operation from a smartphone or tablet is optional.
