Necksterilizer: Application and Function
The necksterilizer consists of three modularly configurable machine segments to ensure the optimal sterilization time:
Modul 2: Expandable units of 2,000 and 3,000 mm sterilization segments and
Modul 3: 5,600 mm outlet with a 2,100 mm sterilization section.
The Whystler Necksterilizer processes PET and Glass Bottles in one line, without changeover times and without format changes.
For wetting the headspace or sterilizing the bottle neck, the PET or glass bottles are tilted by up to 110°C on a sterilization line so that the hot product (e.g., tea or iced tea) reaches the closure area for sterilization. This is made possible by a central SEW motor that drives the high-tech sterilization line with its extra-wide container support. This enables a high flow rate depending on the container type and the sterilization time (> 15 Seconds). The stepless turning curve of the Sterilization chain also guarantees a smooth turning process and very gentle container conveying.
Necksterilizer: Hygienic design
All parts that come into contact with the PET or glass bottle are made of stainless steel and are designed for quick cleaning and easy maintenance. The necksterilizer meets the current hygiene standards of the beverage, food, and pharmaceutical industries.
To ensure these standards, the bottles undergo a light barrier inspection before being turned, which monitors their entry into the sterilization area. The actual turning process is carried out precisely by a combination of a turning chain, a sterilization chain, and a supporting floor guide.

FAQs – Necksterilizer
When is an automated necksterilizer from Whystler the right choice?
A semi- or fully automated necksterilizer from Whystler Automation is particularly suitable for high-performance hot beverage production lines. This is made possible by the sterilization chain with its extra-wide container support and the continuously adjustable rotary motion for controlled rotation. The conveying line can be varied depending on the sterilization time and bottle type. Modular expansion units allow the sterilization line to be extended to a maximum length of 30.2 meters.
How flexible is the Whystler necksterilizer with different bottle formats?
The necksterilizer from Whystler Automation is designed for maximum flexibility in beverage processing. It features format-independent sterilization without mechanical changeovers, making it adaptable to all common PET and glass bottle formats. Furthermore, the stepless turning curve and extra-wide container support of the sterilization chain guarantee a smooth turning process.
How is a consistently high sterilization quality ensured?
Thanks to the precise guidance of the bottles, temperature resistance, and controlled rotation of up to 110°C, the hot liquid reaches the sealing area and thus sterilizes it. This ensures compliance with the stringent hygiene requirements of the beverage and food industries. A comprehensive safety concept with an automated, light-barrier-monitored access system, developed in-house by Whystler Automation, further guarantees consistently high sterilization quality.
Can a Whystler necksterilizer be integrated into existing bottling lines?
Yes. Whystler Automation's necksterilizers are designed for integration into existing hot-filling production lines in the beverage industry. Thanks to their modular design and flexible customization options, they can be optimally adapted to available space, line speeds, and interfaces, and vary in their level of automation.
What economic advantages does a necksterilizer from Whystler automation offer?
In addition to ensuring the highest hygiene standards, companies benefit from high system availability, a maintenance-friendly design, a long service life, and a line output of up to 72,000 bottles per hour. Furthermore, existing bottle necksterilizers can be cost-effectively modernized through retrofitting, thereby promoting sustainability and increasing the economic efficiency of the necksterilizer.
