Aseptic Filler for UHT Milk in PET Bottles

Aseptic system for UHT milk in PET bottles. Closed-loop dynamic weighing with < 1 g precision. Multi-format 250 ml–2 L with 15-min changeover. 12-month shelf life with no cold chain.

Replace multiple laminated carton lines with a single PET filling system that reduces Total Cost of Ownership, minimizes product waste and gives you independence over your container manufacturing. The equipment receives empty bottles and subjects them to a sterilization process with hydrogen peroxide and peracetic acid before entering a sealed cabin with filtered air. Through piston valves, the system doses the UHT milk controlling net weight in real time. Finally, the bottle is hermetically sealed through synchronized capping. The aseptic filler connects directly to the UHT plant outlet, ensuring the product maintains its commercial sterility from the pipeline to ambient temperature distribution.

Main Features and Advantages

Total Cost of Ownership Reduction: Minimizes initial capital expenditure and projected operating costs. Unlike carton systems, this technology generates substantial economic savings by requiring a lower investment in base machinery and reducing dairy product waste during line startups to less than 1%.
Multi-Format Production Flexibility: Allows processing of different volume presentations on the same machine with mechanical adjustment times of just 15 minutes. This eliminates the need to install dedicated filling lines for each size, providing agility to produce individual or family portions on demand, without prolonged interruptions.
Packaging Material Supply Autonomy: By integrating preform blowing in the plant, dependence on contracts tied to a single container manufacturer is eliminated. This allows free negotiation with various raw material suppliers, reducing acquisition costs and decreasing inventory space requirements.
Direct Increase in Profit Margin: The screw-cap bottle format offers greater operational convenience and visual inspection for the end user. These mechanical and functional characteristics allow the dairy product to be positioned at a higher selling price in the market, increasing the profit margin per produced unit compared to the traditional multi-layer carton.

Technical features of the UHT aseptic filler — anti-drip valves and hygienic cabin

•Dynamic closed-loop weighing technology: Guarantees precision with less than 1-gram deviation by resetting the scale at each cycle, eliminating overfilling and ensuring maximum yield from every batch.
•Format flexibility with no additional investment: Allows format changeover (from 250 ml to 2 liters) in just 15 minutes using the same machinery, avoiding the purchase of a dedicated filling line for each size.
•Anti-drip sanitary design valves: Suppress the formation of threads, foam and splashing during dosing, reducing process waste to ranges of 0.5% - 1%, well below losses generated during carton packaging startups.
•Hermetic filling environment: The hygienic cabin ensures product isolation and allows achieving 12 months shelf life without refrigeration, achieving the same technical stability as traditional systems, but in a plastic bottle.
•Integrated cleaning systems (CIP/SIP): Automate disinfectant dosing and thermal sterilization of valves, reducing downtime between productions and ensuring compliance with food safety standards.
