With most carrot crates destined for supermarket shelves , consistent display presentation of the carrots , face up and positioned straight up with the branding and labels clearly visible to consumers is vital
This helps to pre-empt bottlenecks , address production lags and respond instantly if packs get trapped . Should any of these events occur , the upstream packing and checkweighing machines slow or stop automatically until all the processes are in-step with each other again ,” explains Will . “ The speed is very much governed by the processing speed of our baggers and checkweighers . Although the case loader is capable of going faster , we wouldn ’ t want it to compromise the quality of our produce ,” adds Will .
With most carrot crates destined for supermarket shelves , consistent display presentation of the carrots , face up and positioned straight up with the branding and labels clearly visible to consumers is vital . Huntapac ’ s existing merging system and bag flippers ensures that each carrot pack is horizontally aligned before being fed into the Brillopak case packing machine . accumulation towards the crate flap .
The flexibility of the system assists Huntapac to respond to the seasonal peak demands , including the packing of parsnips – another core part of the grower ’ s business . The night shift also regularly runs smaller Chantenay carrots on the line .
FERTILE GROUND FOR GROWTH
With Brexit and COVID compounding the resourcing issue , moving from a fast-paced labour intensive crate loading operation to an automated system has been welcomed by the farm . Better staff satisfaction has been observed by Will : “ Because we are removing the reliance on agency staff , our productivity per person has significantly increased . Our core Huntapac packhouse team was excited to see the machine go in and felt really connected to the project and the wider benefits of eliminating labour intensive routine activities of this nature . The wellbeing , safety , motivational and upskilling advantages were evident from day one .”
Although crate insertion and removal is currently performed at the end of the cell manually , the carrot farmer hasn ’ t ruled out automating the crate destacking and palletising phase to complete its packing automation cycle in the future .
As an extremely marginal business , automation has become an imperative in fresh produce packing operations .
“ In many instances where margins are already compressed , affordable automation can be more effective than implementing traditional lean manufacturing enhancements which tend to only deliver incremental efficiency improvements . Especially when labour input costs are rising higher than fresh produce commodity prices ,” notes David Jahn .
Not only does the reduction of manual work streamline packing processes , it also reduces waste and improves worker safety . Flexible machines which can be adapted to seasonal produce and future packing and product applications further increases their viability , with less risk .
Due to the success of this installation , Will is considering automating case loading on all 16 carrot lines , potentially creating a dedicated parsnips line too .
Will concludes : “ We have been thrilled by the speed in which Brillopak engineered , installed and integrated all the upstream electronics . Within a couple of hours our carrot case loading machine was up and running and hasn ’ t stopped performing since . The level of communication throughout the project was exceptional and I don ’ t recall ever having a machine with this level of complexity run so well from day one .”

Four packs are then presented individually onto a collation support plate , nudging each one along until there are four slightly overlapping packs . Director David Jahn describes the sequence : “ The concept follows a similar principle to a coin pusher arcade game . As one lands on the previous pack , gravity pushes them over to create crate-ready layer .
As soon as the four packs are in position , a side load slider gently pushes the carrot packs onto a flap opening device located directly above the crate . Simultaneously to the carrot packs lowering into the crate , the slider flap lifts , retracts overhead and drops behind the next set of carrots , pushing next
Preston-based Huntapac Produce is laying the groundwork to boost its automation packing efficiency . Starting with a customised Brillopak vegetable case loading system .
