Optimized for flexibility and efficiency, this bag-in-box filler expertly handles high-speed liquid and viscous product packaging, ensuring precise dosing and reducing downtime during changeovers.

Fills and Seals Liquid Bag-in-Box Packages
The Astepo Clean Filler from Alfa Laval is a highly adaptable filling machine designed for dairy, food, and beverage industries, capable of processing liquid products into flexible bag-in-box formats for sizes up to 1,000 liters. This equipment excels with ±0.5% filling accuracy and offers an automatic or semi-automatic operation mode. Utilize its bag-in-box design to support a wide range of products, from milk variants to liquid eggs and sauces. By utilizing a vacuum system to remove residual air and an optional hydrogen peroxide cap flash, the Astepo Clean Filler supports efficient product throughput, extending shelf life by minimizing oxygen exposure. Equipment integration is seamless; its automatic detection system ensures precise cap placement, while its stainless-steel construction, available in AISI 304 or 316, ensures durability under rigorous processing conditions. The filler offers easy changeovers between product runs and supports a high-speed operation mode to maximize your production line’s capacity with rapid cycle turnovers. It also comes with EHEDG compliance for sensitive product processing, making it ideal for producers who demand both flexibility and hygiene.
