KK Cooking System

SORGO KK cooking systems are designed for each project around the product, trolley format, capacity and available heat supply. The cooking function is integrated in every KK system and is also a standard process of the SORGO hot-smoking systems. Typical applications are meat and sausage, poultry, plant-based products and convenience foods.

Process

Products are loaded on their trolley, cooked under controlled conditions, thermally processed as required by the product and configuration, held until the target core temperature is reached and then unloaded. Cooking and thermal processing are separate functions selected per programme.

Airflow

Each trolley position has its own fan motor with a stainless steel impeller made by SORGO. Air distribution is designed for comparable results at the top, bottom, centre, left and right of the trolley, and individual fans can be serviced or replaced separately.

Construction

• Interior and inner floor in stainless steel 1.4571 (V4A), exterior cladding in 1.4301 (V2A).
• Trolley count, row arrangement, trolley dimensions and door configuration define the detailed design.

Heating

The heat source is chosen to match the plant's energy supply:

• HP steam: finned-tube coil built in-house by SORGO from stainless steel 1.4301. The spiral fins give a far larger heat-transfer surface than smooth tubes and therefore a higher efficiency.
• Electric: heating coil made entirely of chromium-nickel steel 1.4876, installed in the upper part of the system.
• Gas or oil: SORGO tubular heat exchanger of thick-walled, heat-resistant steel 1.4876 in the upper part of the system, fired by a high-performance gas or oil burner and designed for low flue-gas temperatures.

Supplementary electric heating is available as an option, for example for weekend operation without steam, for using solar power or for specially designed higher process temperatures.

With direct injection of low-pressure saturated steam, no HP steam heat exchanger is needed for steam cooking; an HP steam coil is added only if an additional cooking function is required.

Options

• Standard cooling shower (active blast chilling is not part of the cooking system).
• Two-fluid atomising nozzle per trolley position.
• Fully automatic CIP cleaning; one station cleans several systems in sequence (CIP pipes are not insulated):
• 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.

Installation and system floor

Three floor designs are available:

• Standard floor: the chamber stands on a finished production floor of sufficient load-bearing capacity; an entry lip or a made-to-measure entry plate gives a safe transition. Simplest building preparation.
• Recessed, flush with the floor: the system is set into a floor opening, levelled with four adjustment screws and grouted with fluid concrete, so heavy trolleys can be pushed straight in.
• Hygienic floor with underfloor cleaning: a sealed, welded system floor stands on adjustable feet in a hygienic tray; two upward-facing nozzles rinse the area underneath.

All three variants can be reinforced for loads of up to 3 tonnes per trolley position.

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.

Sizes

Nine standard sizes from KK3000 (1 trolley) to KK36000 (12 trolleys); the table shows the electric, single-row version.

All table values are guidelines for the standard configuration; every SORGO system is designed and built individually for the product, process, capacity, installation and available utilities.
