The latest snacks packaging technology from Ishida Europe has enabled a leading Serbian potato chips manufacturer to triple capacity and achieve a near doubling in efficiency to meet continuing growing demand.
Facts and figures
Chips Way has invested in three Inspira Integrated Total Packaging Systems (iTPS) comprising of three Ishida RV series 18-head multihead weighers mounted over six Inspira rotary bagmakers
The new snacks packing systems handle potato chips at typically 70-80 bags per minute
The Ishida iTPS are reducing giveaway by 2% compared to the previous packing system whilst the packing speed has increased by almost 100%
Chips Way can now pack in two shifts what it took six shifts to pack previously
Product changeover on the new equipment has been reduced from 20 to just five minutes per system and downtime for cleaning of all packing lines has been reduced from four to just two hours
Established in 1971, Chips Way is one of the leaders in the salty snacks market in Central and Eastern Europe, with its popular Čačanski čips and Gricko extruded snack brands sold throughout Serbia and ten other European countries. With production at its factory at full capacity, the company needed a fast, reliable and efficient solution to effectively handle its ever-increasing orders.
Through its Serbian agent CD System, Ishida supplied and installed three Integrated Total Packaging Systems (iTPS), each one comprising an 18-head Ishida CCW-RV-218 multihead weigher over two Inspira rotary snacks bagmakers with integral throat metal detectors. The fully integrated snacks packing systems deliver maximum efficiency, reliability and flexibility, with close to zero giveaway and film waste, and greater than 99% OEE (Overall Equipment Effectiveness).
“Ishida is a worldwide recognised brand and offers the best performance, quality and service, so they were the obvious choice to deliver the levels of performance that we required,” said Luka Jovanovic, Chief Operating Officer at Chips Way.
At Chips Way the three Ishida iTPS are handling a wide variety of pack sizes from 20 to 280g. For a 40g pack, speeds are between 70 to 80 bags per minute (BPM) per bagmaker, which are well within the machine’s top speed of 120 BPM for potato crisps. This additional performance capacity allows the company to increase packing speeds as demand continues to rise. Pack accuracy and consistency have also improved with the Ishida iTPS reducing giveaway by 2% compared to the company’s previous packing system.
As a result of the improved efficiency, Chips Way can now pack in just two shifts what it took six shifts to pack using the company’s previous equipment, with increases in packing speed per kg by almost 100%.
The Ishida machines are in operation for two eight hour shifts each day. The RV multihead weighers are able to gently handle light and fragile products at high speeds, which are coated with nine different seasonings. With up to three product changeovers required per shift, another major benefit of the iTPS is the quick and easy way in which these changeovers can be carried out.
“A product changeover on the Ishida’s takes just five minutes, whereas on our previous machines it could take as much as 20 minutes,” said Luka Jovanovic. “In addition, the changeovers had to be carried out by technically trained personnel, whereas on the Ishida, only the forming set needs to be changed, and this can be undertaken by the line operator.”
Cleaning has also delivered further time savings, with Chips Way reporting that the regular daily clean after the two shifts now taking just two hours downtime, a 50% downtime saving compared to the previous machines. Similarly, the ease of operation of the iTPS has freed up time in the business’s maintenance department as routine tasks can now be carried out by line personnel.
With a diverse product range, the versatility of the Ishida iTPS has also given Chips Way the flexibility to respond quickly to changing customer orders and requirements.
“For us, the speed and reliability of the Ishida iTPS, its precision weighing and packing, and its ease of changeover and cleaning are all huge benefits,” concluded Luka Jovanovic.
“The machines have provided the foundations for our continued growth, and we will be looking to invest in additional equipment as we seek to further develop our product portfolio.”
