sander hansen shieldThe tunnel pasteuriser
On the safe side sander hansen shield
shield is a fitting name for the product. The tunnel pasteuriser gives delicate products a long shelf life without affecting their flavour. Compared with conventional pas-teurisers, it is distinguished by its low energy and water consumption. This is made possible with the treatment zones with low water volume, the economical heating system chess, the fine-tuned PU control, as well as the economical buffer system. An additional special characteristic are the patented, low-friction con-veyors which transport all container types safely and gently through the pasteuriser. A continuously economical operation is guaranteed by the well-proven technology and the robust design - both are results from our years of experience in building pasteurisers.
shield means protection: Our krones technicians take this liter-ally. Thanks to this, the pasteuriser provides fourfold security protecting products, resources, containers, and production processes.

Method of operation
Channel conceptshield is based on the well-proven channel concept enabling the opti-mum use of pasteurising water. The zone channel is divided into indi-vidual temperature zones so that the water remains in the respective temperature zones also after the bottle treatment. The buffer chan-nel collects overflowing zone water and returns it to the circuit. In the event of a machine stop, cold or warm water is redosed, and there-fore, the required temperature level is reached. The refuse extraction belt filters the water and automatically removes pieces of broken glass.
Tunnel modulesThe tunnel modules are divided into temperature zones which allow gentle container heating and cooling before and after pasteurisation. A special feature of the tunnel module is the spraying system. It distri-butes water over the containers thus achieving a maximum and precisely defined heat transfer. This technol-ogy enables high flow rates at a low pressure.
Application

Design features
■ Modular design of the pasteuriser according to customer-specific requirements
■ Robust and easy-maintenance design
■ Economic water consumption thanks to highly efficient buffer system
■ Regenerative energy concept with continuous utilisation of the zone water
■ Fine-tuned temperature control via zone separation of the channel
■ Low energy consumption through spraying system with low pressure
The infeed and discharge module conveyors are easily accessible with hinged drip plates for perfect cleaning results.
The removable side doors and overhead pipe-work facilitate maintenance.
Optimum acces-sibility to all machine compo-nents and spray-ing system
Spraying with spraying pipes... ...or spraying tubs
Spraying system
krones can supply two different spraying systems:
■ The version with the overhead spray tubes provides even results with its clog-free openings.
■ The base sprinkler version is a low-pressure system with upspray noz-zles distributing the water evenly.
■ Both systems have optimum heat transfer at low electrical consump-tion.

Conveyor systems
■ The materials of the conveyor belts are tailored to your individu-al requirements and containers for safe and efficient transportation.
■ All conveyor belts are made of durable materials and are low on maintenance and wear.
■ Narrow transfer combs are used at the container infeed and discharge points for a streamlined product flow.
■ Due to the low friction of the conveyors, only one main drive is required per deck.
■ Containers which have been left behind are automatically pushed onto the conveyor belt by the optional rotary sweeper, allowing fully automatic operation of the pasteuriser.
■ The Marathon Belt and Ironman Belt can also be retrofitted in existing conveyor systems.
■ Commercial conveyors can be used in the shield as well.
Marathon Belt
■ Patented conveyor of plastic and stainless steel links
■ Extremely long service life and low-wear thanks to minimum fric-tion
■ Best results with all container types
Ironman Belt
■ Stainless steel conveyor■ Special further development of
the well-proven Marathon Belt■ Smooth and safe pasteuriser
operation guaranteed also with increased probability of broken glass

PU control PUC3
Utmost product safety - no matter what: The dynamic PU control PUC3
makes sure the required PU values will be maintained precisely even during product interruptions or in the event of a machine stop.
■ PUC3 determines the PU values in real-time and establishes at the same time a preview of the expected results.
■ At the PU calculation, the thermal properties of the product, the spraying temperature, as well as the conveyor speed are put into consideration.
■ The system allows an on-the-fly product change in the pasteuriser.
■ With the optional multi-criteria control, several target parameters such as PU values and elimination temperature can be controlled at the same time.
■ The Windows-based system ena-bles easy retrofitting of new prod-ucts.

chess heating system
The patented chess heating system enables significantly efficient pas-teuriser operation. shield requires only one heat exchanger which sup-plies the individual zones of the channel directly with hot water. A buffer tank takes up the overflowing water and returns it to the pasteuris-er zones via the heat exchanger.

This closes the water cycle, thereby slashing the heating-up times for the individual zones and saving vast amounts on energy and water con-sumption.
Your advantages sander hansen shield
■ Modular design shield is based on the modular
design principle and is custom-built to your exact specifications in terms of output and available space.
■ Precision PU control Provident PU control guarantees maximum possible product safety: The system reacts dynamically to product deviations and provides continuously high product quality.
■ Savings on energy and water The central heating concept of chess, the zone separation of the channel, and the buffer system drastically reduce the energy and water consumption levels.
■ On-the-fly product change Special software makes it possible to pasteurise two different pro-duct batches at once. This increa-ses the productivity and reduces the water consumption.
■ Fast readiness for operation shield is distinguished by its ex-
tremely short heating times and is ready for operation within min-utes.
■ Optimum conveyor for all con-tainers The Marathon Belt and Ironman Belt conveyors transport your products through the pasteuriser gently and product-friendly.
■ User and maintenance-friendly All shield components are easily accessible. The robust and hard-wearing design of the components also makes it considerably easier to service the machine.
■ Short installation time shield is comprised of modular, pre-installed components and undergoes a full I/O test before delivery. Thus installation at the site can be performed within very short time.
■ Fully automatic operation Containers which have been left behind are put back on course by the rotary sweeper, an optional extra which frees up the operating staff.
