Used Tetra Pak Bottling line for UHT Milk 7500 bph, engineered specifically for the aseptic processing and packaging of UHT milk products in 200 ml Slim carton formats. This industrial bottling line consists of original Tetra Pak machinery, including the Tetra Pak TBA/19-30V aseptic filler, integrated with a Tetra Pak automatic conveyor system equipped with Easy Ride accumulation, an automatic straw applicator (TSA 21), and a secondary packaging unit (CBP 70). Each component is engineered for continuous operation and seamless integration, ensuring product safety, operational efficiency, and compliance with international standards for long-life dairy products.

The entire line is built for aseptic processing, managing the forming, filling, closing, accessory application, and secondary packaging of UHT milk in a fully automated sequence. The process ensures high levels of product hygiene, packaging integrity, and line efficiency, supporting industrial-scale operations.

Aseptic Filling Section and Product Handling

At the heart of this line is the Tetra Pak Tetra Brik Aseptic TBA/19 – 30V filling machine, dedicated to producing 200 ml Slim cartons. The aseptic configuration includes a packaging material sterilization process using a hydrogen peroxide (H₂O₂) bath, followed by drying with sterile air. This ensures the complete microbial decontamination of the carton’s internal surfaces before filling.

Filling occurs inside a controlled sterile chamber, which maintains positive pressure isolation from the external environment, guaranteeing the microbiological safety of the UHT milk during packaging. The filling system utilizes a high-precision volumetric dosing head with electronic flow and level control, ensuring consistent, repeatable filling for every package.

Sealing of the carton (both longitudinal and top) is achieved through heat sealing, ensuring tight closure and package integrity. All main mechanical operations are managed by an integrated automation system, which continuously monitors and controls temperature, pressure, and exposure times for each critical phase of the cycle.

Automation, Quality Control, and End-of-Line

This Used Tetra Pak Bottling line for UHT Milk 7500 bph is fully automated via a centralized control panel, with real-time management of all operational parameters for the filler and connected machinery. Each section is equipped with sensors, photocells, safety devices, and operator panels for process diagnostics and fine-tuning. The machines communicate through standardized fieldbus systems and hardwired connections, ensuring perfect synchronization during format changes or start-stop cycles.

Product transport is handled by the Tetra Pak Package Conveyor 21 system, integrated with Easy Ride accumulation. This guarantees smooth handling and continuous alignment of cartons between each stage, providing a buffer of approximately 3 minutes to compensate for minor downstream stoppages and to prevent carton tipping.

The Tetra Pak Straw Applicator 21 (TSA 21) is dedicated to the precise application of paper straws onto the Slim cartons, using Nordson hotmelt adhesive technology. This applicator operates at high speed, fully integrated with the main filler to match production rates and ensure accuracy.

Secondary packaging is managed by the Tetra Pak Cardboard Packer 70 (CBP 70), which automatically packs finished cartons into corrugated cardboard cases. The unit supports flexible packing patterns and is currently configured for 3×8 (24 cartons per case) using Nordson Problue hotmelt gluing technology. The CBP 70 is adaptable for alternative packaging schemes as needed for logistics or distribution.

All main machines are fitted with integrated hour meters, automatic anomaly detection, quality control systems for seal integrity, and reject management for off-spec products. The main power supply for the line is 400/230 Volt, 50 Hz.
