The bottle unscrambler (Uhlmann BU 300) machine is a perfect choice for efficient feeding of round, rectangular, oval or square bottles of various sizes upright into a production line, optionally with air rinsing. Its compact design allows fast format changeovers, for maximum flexibility. The highly reliable process of the automatic bottle unscrambler BU 300 handles bottles gently, while maintenance and cleaning are easy. The intuitive HMI with SmartControl enables user-friendly operation, generating audit-trail reports, statistics and connectivity with other machines. All these factors result in the remarkably high economic efficiency of the automatic bottle unscrambler machine.
How does a bottle unscrambler work?
The bottle unscrambler machine is a highly efficient and user-friendly machine designed to sort and arrange bottles in an upright position, to feed a bottle production line. The hopper can be loaded via the convenient entry slide, and its impressive 700-liter holding capacity allows for extended refill intervals, reducing downtime. The bottles are transported with a bottle elevator and gently dropped into the sorter bowl. The centrifugal system in the sorter bowl gets the bottles into the alignment system. A hook ensures that all bottles face the same direction by hooking into the opening and flipping the bottle over. Finally, the bottles stand upright with the opening facing upwards and can be transported downstream to the next machine.

Now that we have explained the configuration of the automatic BU 300, we will highlight the 6 main advantages of the bottle unscrambler.
1. Experience the speed and efficiency
With the automatic bottle unscrambler, BU 300, you’ll experience the benefits of a high-speed, adaptable, and user-friendly solution that streamlines your production process, helping you achieve optimal efficiency and productivity. Running 300 bottles per minute, this highly efficient machine is perfect for handling bottles ranging from 25 to 125 mm in diameter.
Thanks to its fast and repeatable format changeover process, you can effortlessly adjust the machine within just 10 minutes – no special tools or format parts required! This means you can quickly switch between different bottle sizes without any hassle, allowing you to maximize production flexibility and stay ahead of changing demands.
2. Simple process without brush on sorter
Unlike earlier bottle unscrambler machines that lacked servo control and relied on brushes, the BU 300 introduces a revolutionary sorting process that is both simple and highly efficient. The integrated bottle elevator is thoughtfully equipped with noise-reducing covers and a silent drop station, gently guiding bottles into the sorter bowl. No more worrying about disruptive noises or product damage during the sorting process – the BU 300 ensures a significantly quieter operation, creating a more pleasant working environment for your team.
The BU 300’s sorter bowl is capable of handling both round, rectangular, oval and square-shaped bottles of varying diameters. This system is designed without the need for a bottle brush that guarantees a gentler touch on your valuable products. Furthermore, the programmable variable bottle speed and jam control features work together seamlessly, ensuring a smooth and accurate introduction of bottles into the alignment system. Enjoy a precise control mechanism that optimizes the machine’s performance, reducing downtime and maximizing overall production efficiency.
3. Spring loaded bottle control
The incorporation of a spring-loaded belt control offers unmatched flexibility. Regardless of bottle size deviations, the system remains tolerant and maintains stable settings, providing a consistent and reliable bottle grip throughout the entire process. With the BU 300 sorter bowl, you can optimize your production line’s performance.
4. Exceptional accessibility and cleanability
The balcony design of the bottle unscrambler offers a significant advantage over conventional machines, thanks to its exceptional accessibility and cleanability features. In industries where precision, hygiene, and productivity are non-negotiable, the BU 300’s cleanable aspect takes center stage. Especially in pharmaceutical applications, maintaining stringent hygiene standards is paramount. Smooth surfaces minimize the risk of contamination and ensure consistently hygienic production. With its open and spacious layout, the BU 300 makes thorough cleaning a straightforward process, reducing downtime and enhancing productivity.
5. Unlock Efficiency and Control with SmartControl HMI
All machine processes of the bottle unscrambler are controlled via SmartControl, a human-machine interface (HMI) with a touchscreen. This HMI puts you in command of all machine processes, offering unparalleled control and ease of operation. The graphical user interface ensures intuitive navigation throughout the machine, making setup and operation a breeze.
Moreover, all format data is securely stored in the control system, allowing for SmartControl’s audit-trail reporting and generating detailed statistics, including bottle counters, downtime , waiting time, and production time. This invaluable insight empowers you to make data-driven decisions and optimize production processes.
Connectivity is a key advantage of SmartControl. With its built-in capabilities, it seamlessly communicates with other machines. Together with the Pexcite software platform, various machines and components can be coordinated, streamlining the production process for maximum efficiency.

6. Bottle Cleaning
In the pharmaceutical industry, maintaining clean and hygienic bottles is not just a preference – it’s a necessity. That’s why the BU 300 offers an optional bottle cleaning feature, ensuring that your products meet the highest standards of cleanliness and safety. With the innovative bottle blowing system, powered by a clean air filter (0.2 μ), every bottle is thoroughly cleaned. This advanced technology removes dust, particles, and other contaminants, leaving your bottles clean and ready for pharmaceutical applications.
Three ionized air blow nozzles take the cleaning process to the next level. These powerful nozzles efficiently remove static electricity and release particles ensuring that your pharmaceutical products are free from any potential impurities. The BU 300’s vacuum system expertly removes the foreign particles. This careful approach to bottle cleaning ensures that every bottle meets the highest hygiene standards and that you can be confident of the quality of your products.
Enhancing production with innovative features
The innovative design and user-friendly features of the bottle unscrambler machine make it an excellent choice for industries seeking reliable bottle handling solutions. It’s a versatile and highly efficient solution for feeding different-sized round or square bottles upright into a production line, with the option for air rinsing if needed. The design allows for fast format changeovers, ensuring maximum flexibility and adaptability to various production environments. The central intuitive HMI with SmartControl, empowers users with user-friendly operation, audit-trail reporting, statistics, and seamless connectivity to other machines. This combination of features contributes to the BU 300’s exceptional economic efficiency.
