Simplifying bag filling
3 April 2012 – Flexicon Europe has introduced a pneumatic gain-in-weight filling system
The system automates delivery of free-flowing bulk solids from down-stream silos or processing lines to individual bulk bags. Typically within confectionery applications, the equipment could be used for transferring sugar, cocoa and milk powders,caffeine, cake mixes, nuts (ground and whole), etc
The filter receiver of the Pneumati-Con vacuum dilute-phase pneumatic conveying system is mounted on load cells, enabling the weight of incoming material to be recorded at high rates and then at steady dribble-feed rates, stopping the flow once an accurate batch weight has been reached.
Pressing a ‘fill’ button on the control panel actuates a bag inflation blower on the Twin-Centerpost bulk bag filler to remove creases in the bag, simultaneously opening a slide gate valve at the outlet of the filter receiver allowing the weighed batch to gravity discharge into the bag at high rates, a vibratory deck densifies the material to stabilise the bag.
A secondary set of load cells mounted beneath the bulk bag filler allows the system to confirm the final weight of the filled bulk bag. The bag straps are then released and the spout seal deflated, allowing the operator to tie-off the spout and remove the filled bag.
While filled bags are being removed and empty bags attached, a subsequent batch is being conveyed to the filter receiver and weighed, ready for another fill cycle.
