Harvesting savings on baked goods lines
Rising wheat and energy prices could put bread and baked goods supply chains at risk cautioned CEO of the Federation of Bakers recently . To help curb these escalating macroeconomic costs , food inspection specialist Fortress Technology unveils how automated technologies can be deployed by industrial bakeries to reduce giveaway and false rejects and boost productivity .
Before the Ukraine conflict , bakers were already digging in and preparing for a bumpy ride , with rising commodity and import prices adding an extra 4.5 pence to the production costs of an 800 gram bread loaf . In the last six months , production costs have more than doubled again , claims the Federation of Bakers .
Naturally , the cost of flour contributes to these hikes . However , it ’ s the higher energy consumption figures from running machinery , ovens and keeping the production lights on that impacts the final costs more . Making it even more imperative to uncover the causes of upstream losses and counteract batches of baked goods being wasted because they were out of tolerance before reaching the ovens .
Automated weight monitoring Checking the weight of baked goods before the proving phase is pertinent . As is maintaining consistent processing and checkweighing speeds . The reason , explains Fortress Technology ’ s Commercial Manager Jodie Curry , is to factor in processing variables and ensure products aren ’ t out of tolerance before baking .
“ Leaving until the final stage of the process could result in an entire batch being over or underweight . Potentially costing a bakery over four hours of lost production time and thousands of wasted product being binned ,” cautions Jodie
Additionally , a bread loaf may weigh 800 grams when baked , but in its raw state is 917 grams . If it is out of tolerance by just a few grams , dough can overspill and potentially spoil other loaves during baking . Plus , if one is overweight there will definitely be an underweight loaf in the batch .
Guaranteeing uniform portion weights , the
Dough that is 0.5 grams over or under weight is automatically rejected beneath the system for reworking
Fortress Technology ’ s unique unclippable and ‘ no-tool ’ conveyor optimises Clean In Place ( CIP ) standards
Fortress Hestia Dough Checkweigher - used for all sorts of baked goods applications - from pizza to baps , French sticks to cakes and crumpets to traditional loaves - inspects up to 12,000 dough pieces per hour . Connected to an automated upstream dough dividing line , if a piece of dough is under or overweight by as little as 0.5 grams , the Dough Checkweigher automatically rejects it . Simultaneously , the machine ’ s advanced fibre optic controlled software communicates back to the dough divider in real time to adjust the position of the blade for the next batch . For optimum processing flexibility , Fortress can pre-programme up to 500 different product codes , ranging from 150 grams to six kilograms .
“ Every big bakery started off performing these dough dividing and weight check tasks by hand . Not only is this labour intensive , but also leads to variations in product quality . For commercial as well as artisan bakers , automated dough checkweighing allows for individual pieces that are off target weight to be removed and reworked , as well as providing corrective feedback to the dough divider ,” emphasises Jodie .
Data gathered via the management control system can also help to track uptime and address line inefficiencies . Using the swipe touchscreen , baking operatives can select the statistical parameters most relevant to their operation . The easy to use graphical display automatically logs and reports Reject Integrity compliance tests . This intuitive digital interface also helps to significantly reduce set up time between each batch .
