[vc_row][vc_column][vc_column_text]The automation of food production presents immense challenges, not least because of the stringent hygiene standards and the difficulties involved in handling the products. PINTRO bv of Belgium has come up with a novel solution: Their fully automated Pick & Skewer system<\/a> for the preparation of kebabs is a world first. St\u00e4ubli<\/a> robots with wash-down capability are responsible for handling and precisely skewering ingredients. <\/strong>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/6″][\/vc_column][vc_column width=”2\/3″][vc_raw_html]JTNDaWZyYW1lJTIwd2lkdGglM0QlMjI1NjAlMjIlMjBoZWlnaHQlM0QlMjIzMTUlMjIlMjBzcmMlM0QlMjJodHRwcyUzQSUyRiUyRnd3dy55b3V0dWJlLmNvbSUyRmVtYmVkJTJGWl9pcGV3RkhVMHclMjIlMjB0aXRsZSUzRCUyMllvdVR1YmUlMjB2aWRlbyUyMHBsYXllciUyMiUyMGZyYW1lYm9yZGVyJTNEJTIyMCUyMiUyMGFsbG93JTNEJTIyYWNjZWxlcm9tZXRlciUzQiUyMGF1dG9wbGF5JTNCJTIwY2xpcGJvYXJkLXdyaXRlJTNCJTIwZW5jcnlwdGVkLW1lZGlhJTNCJTIwZ3lyb3Njb3BlJTNCJTIwcGljdHVyZS1pbi1waWN0dXJlJTNCJTIwd2ViLXNoYXJlJTIyJTIwYWxsb3dmdWxsc2NyZWVuJTNFJTNDJTJGaWZyYW1lJTNF[\/vc_raw_html][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=”15px”][vc_column_text css=””]Shashlik, souvlaki, kebab and satay \u2013 all variations on the theme of skewered meat \u2013 enjoy great popularity with consumers. The 160-strong workforce at Beltaste N.V<\/a>.\u2019s production facility in Morahalom, southern Hungary, produces mainly shish kebabs. In the eyes of automation experts in this field, it is considered a pioneer of \u201cFood Processing 4.0\u201d, i.e. the fourth generation of manufacturing technology. This is because the world\u2019s first fully automatic skewering machine was commissioned there a year and a half ago, and Beltaste has since installed a second one.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=”11023″ img_size=”large”][vc_empty_space height=”15px”][vc_column_text]High-speed kebab production<\/strong><\/p>\n

To follow how the fully automated Pick & Skewer system functions with the naked eye, maximum concentration is required, as the process runs at a formidable speed. The ingredients are fed in on two conveyor belts at the central point of the production line, with breaded, raw or marinated meat on one track, and onions, peppers, cherry tomatoes or whatever else the recipe calls for on the other. Positioned at the side of the system are the mechanisms in which the ingredients are separated and held ready for horizontal skewering.<\/p>\n

The task of the St\u00e4ubli robots is to grip the ingredients and ensure that the skewer pierces them exactly through their center. The finished kebabs are then conveyed to the packaging station. The Beltaste system produces between 1,000 and 1,200 shish kebabs per hour without human intervention. And every single one is of top quality.<\/p>\n

It was precisely this level of performance that prompted senior management at Beltaste to invest in the world\u2019s first Pick & Skewer system. As Leon Muyshondt, Chief Technology Officer at Beltaste in Morahalom explains, \u201cWe spent ages looking for a solution that would increase productivity and at the same time improve quality, but we found nothing suitable. When we saw the Pick & Skewer, we were immediately won over. We believed in the concept and had confidence in the developer and manufacturer.\u201d[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=”11028″ img_size=”large”][vc_empty_space height=”15px”][vc_column_text]Five robots skewer 15,000 separate ingredients per hour<\/strong><\/p>\n

The system was developed by the Belgian company PINTRO bv. Its name is a simplified form of the English phrase \u201cpin through\u201d. Since 2007, this subsidiary of the special equipment manufacturer SMO bv has been producing machinery for the manual or semi-automatic production of kebabs.<\/p>\n

The Pick & Skewer has enabled a quantum leap to fully automated production of kebabs \u2013 and on a large scale too. Depending on the desired output, a minimum of two and a maximum of five robots pick all of the ingredients and hold them ready for skewering. Beltaste opted for the version with five top-of-the-line St\u00e4ubli TX2-60L HE robots. Because one six-axis robot is capable of picking and skewering up to 3,000 separate ingredients per hour, the system achieves a maximum throughput of 15,000 ingredients. At 10 per skewer, that is equivalent to 1,500 kebabs per hour.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]Flexible recipe changeover<\/strong><\/p>\n

The robots are guided by vision systems and work their way through the recipes stored in the control system. In doing so, they are not only fast, but also versatile. \u201cWe generally vary the recipe every 16 to 20 hours. If this involves swapping grippers, it only takes five minutes thanks to the quick-change systems,\u201d says Muyshondt.<\/p>\n

The PINTRO engineers have invested a lot of know-how in the development of the grippers. The result is a combination of mechanical and vacuum grippers that picks multiple different ingredients in a single pass and then pierces them with pinpoint accuracy \u2013 otherwise the high level of performance could not be achieved.<\/p>\n

Each robot produces its individual complete kebab within seconds. The exact position of each individual ingredient is continuously monitored by the image processing systems. Pieter Weyens, Head of PINTRO: \u201cThe ceiling-mounted St\u00e4ubli robots grip and position each ingredient with an accuracy of \u00b1 0.1 mm. Precise positioning and alignment are not the only criteria that matter here. It is also important that the kebabs look as if they have been handmade.\u201d[\/vc_column_text][vc_empty_space height=”15px”][vc_single_image image=”11027″ img_size=”large”][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=”15px”][vc_column_text]Selecting the robot: hygiene as the deciding factor<\/strong><\/p>\n

In addition to speed and precision, hygiene and cleanability also played key roles in the selection of the robot. The cleaning procedures are robust, as Muyshondt describes: \u201cTwice a day, we run an automatic cleaning and disinfection cycle of the tools, which takes one and a half minutes each time. After every shift, the equipment is thoroughly cleaned and disinfected: first foam is applied, then it is hosed down with hot water from a 40-bar cleaning lance \u2013 and that includes the robots.\u201d<\/p>\n

The HE (humid environment) version of the six-axis St\u00e4ubli TX2 robot is waterproof and thus eminently suited for this requirement profile. It is fully encapsulated and withstands the cleaning run without any impairment of function. Even frequent and intensive cleaning processes, such as those prevalent in the pharmaceutical and food industries, do not lead to any reduction in service life. Further, HE robots are designed to operate even in sensitive environments. Their wash-down compatible hygienic design is considered unique.<\/p>\n

The robots used in the skewering system are also lubricated with food-grade NSF H1 oil. \u201cThe robots are subjected to a heavy workload, because they perform a lot of rapid and delicate movements. So the lubricant has to be efficient and at the same time meet the requirements of the food processing industry,\u201d says Muyshondt. The H1 oil that St\u00e4ubli developed in collaboration with an established lubricant manufacturer meets these criteria perfectly.[\/vc_column_text][vc_empty_space height=”15px”][vc_single_image image=”11025″ img_size=”large”][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/6″][\/vc_column][vc_column width=”2\/3″][vc_empty_space height=”15px”][vc_raw_html]JTNDaWZyYW1lJTIwd2lkdGglM0QlMjI1NjAlMjIlMjBoZWlnaHQlM0QlMjIzMTUlMjIlMjBzcmMlM0QlMjJodHRwcyUzQSUyRiUyRnd3dy55b3V0dWJlLmNvbSUyRmVtYmVkJTJGTnBnbHd0VlBYOU0lMjIlMjB0aXRsZSUzRCUyMllvdVR1YmUlMjB2aWRlbyUyMHBsYXllciUyMiUyMGZyYW1lYm9yZGVyJTNEJTIyMCUyMiUyMGFsbG93JTNEJTIyYWNjZWxlcm9tZXRlciUzQiUyMGF1dG9wbGF5JTNCJTIwY2xpcGJvYXJkLXdyaXRlJTNCJTIwZW5jcnlwdGVkLW1lZGlhJTNCJTIwZ3lyb3Njb3BlJTNCJTIwcGljdHVyZS1pbi1waWN0dXJlJTNCJTIwd2ViLXNoYXJlJTIyJTIwYWxsb3dmdWxsc2NyZWVuJTNFJTNDJTJGaWZyYW1lJTNF[\/vc_raw_html][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=”15px”][vc_column_text]Simple programming, together with even simpler operation <\/strong><\/p>\n

Coordinating image processing and robot movements at this speed and with the requisite precision also places high demands on the robot controller. This is another area in which the machines score high marks: St\u00e4ubli CS9 controllers are known for their high performance and also for excellent connectivity. A further advantage is their simplicity of programming.<\/p>\n

Users of the Pick & Skewer have it even easier, as Muyshondt explains: \u201cThe employee simply selects a recipe, loads the ingredients, and presses the start button \u2013 job done!\u201d While kebab production is running, ingredients can be added. And the image processing systems also oversee the quality control of each individual skewer.<\/p>\n

A concept with many advantages<\/strong><\/p>\n

In the Pick & Skewer, PINTRO has developed a worldwide first for the food processing industry, clearing high hurdles along the way \u2013 for example, with the design of grippers that pick and place onion slices and cherry tomatoes at speeds almost too fast for the human eye to follow. Because the system handles raw meat, the entire process must be carried out under the strictest hygienic conditions, which is thankfully not a problem for St\u00e4ubli HE robots.<\/p>\n

From the perspective of the early adopters, the concept offers clear advantages. Muyshondt is enthusiastic: \u201cThe quality of the kebabs is consistently high. The ingredients are skewered precisely, and we have a free choice of ingredients. Cleaning and disinfection times are extremely short, and the robots can be hosed down at the same time. This is the future of kebab production.\u201d With the first Pick & Skewer line having been such a huge success, a second one has recently gone into operation at the Beltaste factory in Hungary.[\/vc_column_text][vc_empty_space height=”15px”][vc_single_image image=”11026″ img_size=”large”][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
