Used HDPE dairy bottling line, 7,200 bph: structure and production capacity. The used HDPE dairy bottling line, 7,200 bph, processes and bottles dairy products in high-density polyethylene (HDPE) containers. The line operates at a rated capacity of 7,200 bottles per hour, optimized for a 0.40-liter format. It uses HDPE bottles weighing 19-20 grams, each closed with a 3.2-gram polyethylene (PE) snap cap. Although the system was inactive from 2018-2019, technicians completed a complete overhaul prior to commissioning. As a result, the used Serac HDPE bottling line remains in good mechanical condition. Container Type and Format Flexibility of the Used HDPE Bottling Line The Serac Used HDPE Bottling Line handles 400 ml HDPE bottles with snap-on PE caps and sealed with an aluminum membrane. Its weight-based filling technology ensures high accuracy and hygiene compliance, essential for dairy processing. Specifically, this configuration of the Serac Used HDPE Bottling Line is suitable for still liquid products. Additionally, operators can upgrade the system to handle 500 ml bottles with only minimal adjustments required. Unlike threaded capping systems, this line uses a push-on closure, which simplifies maintenance and improves seal consistency. Therefore, it provides an effective and reliable solution for bottling in sensitive food sectors. Feeding and Bottle Preparation Section At the beginning of the Serac Used HDPE Bottling Line process, the bottle unscrambler, built by Lanfranchi in 2008, feeds loose HDPE bottles into the conveyor system in the correct orientation. Meanwhile, an Auto Jet Spray unit from Autojet Technologies (2012) cleans the bottle necks using high-pressure air jets, effectively removing any dust or particles. Additionally, Lanfranchi conveyors installed in 2008 transport bottles between stations while maintaining consistent line flow and bottle spacing. These components ensure mechanical integrity and reduce handling errors. As a result, the Serac used HDPE bottling line achieves both efficiency and reliability in its initial stages. Weight-by-Weight Filling and Snap-Cap Capping The Serac used HDPE bottling line, manufactured in 2008, is equipped with 12 weight-by-weight filling heads that ensure precise product dosing. After the filler, a Zalkin cap sorter (U9000, 2008) orients and feeds the snap caps to the SERAC cap press (CAP PRESSMP2, 2008). The press then applies each cap to the bottle with controlled vertical pressure. Meanwhile, a foil applicator applies a seal to the mouth of the container before the cap is pressed. The absence of torque-driven screw components simplifies operation and reduces wear over time. Sleeve labeling and final packaging of the used HDPE bottling line After capping, the labeling phase begins on the 7200 bph used HDPE dairy bottling line. The FINPAC (2008) sleeving system includes a sleeve roller (SBUO. UOPP/0), a liner (SHMB1), and a shrink tunnel (TV250). Together, they apply full-body shrink sleeves to each bottle. In the final stage of the used Serac HDPE bottling line, the PRASMATIC shrinkwrapper (M&W 300C, 2008) wraps the finished bottles into packages for transport and storage. Ultimately, this configuration ensures a continuous end-of-line process that meets the industrial dairy packaging requirements for the used Serac HDPE bottling line.
