The packaging solution for vegetable dishes from HAK
A complete production line has been designed and installed for filling the pre-formed stand-up pouches with the HAK vegetable dishes, from unloading the big bags to the outfeed belt fitted with a bag roller.
2 big bags hang in an unloading system and are unloaded simultaneously with the possibility to process 2 different products such as beans and dry legumes or vegetables (peas, carrots, maize, green beans, beet cubes). Below the unloading stations are 2 short vibrating troughs to load the Z-feeder conveyors evenly. These elevator belts ensure a controlled supply from the bulk to again 2 vibrating troughs, these are placed at the top of the platform. Various sensors regulate the level in the vibrating feeders and ensure an automatic start/stop.
Both tracks are used to supply a multihead weigher with product. By means of a diverter valve between the multihead weigher and the Leepack stand-up pouch packaging machine, a certain amount of legumes/vegetables is always poured into the bag. After depositing these solid components, the sauce is filled into the bag with a piston filler. After that, the filling is ready and a gas mixture is added for the sake of shelf life. The bag is then closed with an ultrasonic seal to guarantee a tight bag. To create a nice sealing edge on the bag, a heat seal is also applied. The bags then leave the Leepack machine and are flattened with a roller for further automatic downstream processing.
