Recirculating-air cooling
The process air is cooled by the cooling coils.

Blast chilling systems
SORGO intensive cooling systems combine cold air, water and mist showers with compact stainless steel finned-tube coils. Rapidly through critical temperature ranges – controlled cooling to the desired core temperature.

APPLICATION AREAS
COOLING METHODS
The process air is cooled by the cooling coils.
Water supports targeted heat removal.
Twin-fluid atomising nozzles supplement the cooling at each loading trolley.
YOUR BENEFITS
Critical temperature ranges are passed through quickly and in a controlled manner.
Rapid, controlled cooling protects product yield.
The desired core temperature is reached without intermediate storage.
Cold storage rooms and additional storage areas can be saved.
COOLING PROCESSES & OPTIONS
Cooling takes place in parallel through powerful, targeted recirculating air and an integrated cooling shower. This removes heat from the product quickly and evenly.
The system can optionally be equipped with a special stainless steel 1.4301 two-fluid atomising nozzle per loading trolley. Operating with compressed air and water, it sprays hot, hanging or horizontally placed products with microfine mist. The greatly increased water surface area improves evaporative cooling: heat is removed from the product while water consumption remains low.
INTENSIVE COOLING
Two cooling coils in the side supply air ducts.
COOLING COILS
Intensive cooling is provided by two cooling coils in 1.4301 stainless steel, installed on the left and right in the supply air ducts. Here, the circulating process air is cooled and returned to the product.
The coils operate on the counterflow principle to achieve optimal efficiency. Their finned-tube design provides a large heat transfer surface.
AIR DISTRIBUTION & MAINTENANCE
Powerful air movement supports short cooling times and protects product yield.
Air distribution is designed for comparable conditions at the top, bottom, centre, left and right of the trolley.
Each trolley position has its own fan motor with a stainless steel impeller manufactured in-house by SORGO.
Individual fans can be serviced selectively and replaced individually in multi-trolley systems.
If an individual fan fails, functioning trolley positions in a multi-trolley system remain usable.
OPTIONAL CIP CLEANING
Available as an option. The programme-controlled system performs cleaning, contact time and fresh-water rinsing of the system.
The CIP pipes are not insulated.
One central station supplies several connected systems and cleans them automatically in sequence.
Cleaning agent dosing can be adjusted from 1 to 10%.
A powerful stainless steel pump provides a cleaning pressure of approximately 10 bar. This makes the system independent of the customer's mains water pressure.
After cleaning and contact time, the system automatically rinses with clean water.
CONTROL & DOCUMENTATION
Intuitive operation on a 15.6-inch industrial touchscreen, storable programmes and precise process control. Also discover SORGO INSPECT for central documentation and optional remote operation via smartphone or tablet.

TAILORED TO YOUR NEEDS
Capacity, product, trolley format, energy supply, room layout and level of automation determine the solution. SORGO plans every system for the actual operating workflow – including controls, smoke system, cleaning, documentation, installation and commissioning.
