The key components
The design: PET-AseptBloc L with blow moulder

aseptic filler
Filling valve
• The appropriate filling valve for the most wide range of products – still and carbonated
• It is also suitable for beverages with (fruit) pieces of a size of up to 10 x 10 x 10 millimetres
Cleaning and change-over
• The filler has its own CIP module – thus no separate CIP system is required.
• The filling valves are sterilised with steam.
• The clean room housing is sterilised with peracetic acid.
• Handling parts change-over is possible up to a defined output in an automatic way.
• After an intervention into the clean room housing, there will be an intermediate sterilisation with peracetic acid within 30 minutes.
aseptic capper
Technical features
• Every capping head has its own separate servo drive.
• A transfer tunnel separates the sterile area from the outside area.
• The proper technique for every cap – overcaps with round bottle possible!
Hygiene
• The Krones aseptic capper is always in a hygienic design and meets even the most difficult hygiene requirements.
• All drives are outside the clean room housing.
• A liquid seal system seals all of the capper carrousel’s rotational movements.
• The movements of the capping head are sealed with bellows.
• Depending on the type of cap, a cone capper or a gripper capper are used.
Cleaning and change-over
• The open design enables excellent cleaning of all capping heads.
• The handling parts adjustment system operates fully automatically up to a defined speed.
Cap sterilisation module – two variants
After cap inspection, the caps are sterilised with the appropriate system.
Cap inspection unit checks caps for: Deformation, ovality, intact cap tamper-evident rings and correct orientation
For all sterilisable caps: dry cap sterilisation by means of H₂O₂
Technical features
• Simple mechanical design
• Sterilisation of the caps by means of hydrogen peroxide steam
• Short treatment time at high temperature
• Treatment with the precise number of caps: The last cap for the last bottle
For submergible caps: PAA immersion bath
Technical features
• Simple mechanical design
• Cap sterilisation by means of liquid peracetic acid
• Spraying with sterile water and blow-drying with sterile air
Rinser
• Removes residual peracetic acid from the containers
• Efficient single-channel full cone nozzle with adjusted dimensions
Without CIP cups
Open SIP in the clean room housing
• Reduced water consumption
• Time saved during rinsing and cleaning
• Recycling of the peracetic acid
• Recycling of sterile water
Container sterilizer
Interior treatment of the containers
• Steam as carrier and activator of peracetic acid
• Spreader-shaped nozzles for thorough cleaning of the neck area
Exterior treatment of the containers
• Continuous exterior treatment with liquid peracetic acid at a temperature of 45 and 60 °C
At a glance
• Re-use of the liquid peracetic acid from steriliser and rinser for the exterior treatment of the containers
• Best draining properties thanks to a Krones Tabletec table top inclined on one side
• No use of surface-active agents
Benefits to you
Smaller installation surface
- Linear machine design
- Integration of the valve block into the machine frame
- Unburdened rinser
- Reduction of the sterilisation modules from three to one
- Integrated, decentralised ventilation technology – no additional controller required
Reduced operation and maintenance work involved
- Tabletec table top inclined to one side
- Integration of the valve block into the machine frame
- Capper in hygienic design
Highly efficient and safe sterilisation
- Spreader-type nozzles for reliable interior treatment of the containers, even in the neck-finish area
- No surface-active agents required
- Hermetically isolated sterile areas
Energy efficiency and environmental friendliness
- No surface-active agents required
- Re-use of rinsing water
- The single-channel rinser with improved nozzles reduces the air consumption
- Lower energy consumption thanks to a modified ventilation system
High output
- Minimum loss of product during type change-over by product supply to the filler from the top
- Reduced SIP time by steam sterilisation of the filling valves
- No CIP cups therefore faster and easier operation
- Product change-over: from the last bottle to the first within a mere 150 minutes
