Frozen Vegetable VFFS Packaging Machine Guide

Frozen vegetables are commonly weighed and discharged vertically into formed bags, making VFFS a natural platform to evaluate. However, cold product, surface moisture, ice, product bridging and the production environment can affect weighing, film handling and seal quality.

Published HYS Configuration Facts

• Published VFFS speed range: 25-55 bags/min
• Published VFFS bags extend to L 320 x W 250 mm across the models
• VFFS product page describes automatic forming, filling, coding and sealing
• Cold-environment and multihead-weigher configuration require project confirmation

Final model, options, accuracy and output are confirmed from product and package samples.

Custom functions: Nitrogen flushing, dust extraction, metal detection and checkweighing require a customized machine or line configuration.

Feeding and Weighing

• A multihead weigher is commonly evaluated for mixed or free-flowing frozen pieces.
• Product temperature, stickiness, clumping and piece-size variation affect stable feeding and accuracy.
• Transfer surfaces and timing should minimize product damage and prevent buildup.
• The line layout must coordinate elevator, weigher, bagger and discharge equipment.

Film and Cold-Environment Factors

• Specify film structure, low-temperature performance, sealing window and required barrier.
• Condensation control and dry seal areas are important for consistent package integrity.
• Bag width, length, fill weight and headspace determine the forming set and cycle time.
• Electrical enclosures and cleaning methods should suit the installation environment.

Validation Checklist

• Frozen product sample and temperature range.
• Target weight, tolerance, bag dimensions and film roll.
• Required bags per minute and upstream supply rate.
• Cleaning, food-contact, coding, inspection and downstream requirements.
