This machine is a fully automatic thermoforming vacuum packaging unit tailored to candied fruit, dried fruit and preserves such as raisins, dried cranberries, dried mango, peach and apricot preserves and preserved plums. It needs no pre-made bags and instead forms trays directly from the upper and lower roll film.
The process runs as a continuous line: the bottom film is heated and stretched into cavities that match the product; the product is loaded by hand or by a robot; the top film covers it and air is drawn out to create a vacuum or nitrogen is added; the films are then heat sealed and cut into individual packs. Vacuum or nitrogen flushing helps prevent the fruit from sticking, getting damp, re-crystallizing, clumping or oxidizing and changing color.
The work flow has four main stages: vacuum, heat sealing, air return and cycle. After the chamber is evacuated to the set vacuum level the sealing chamber is pressurized to press down on the bag opening and seal it; air is then returned to reset the sealing frame and open the chamber lid; the chamber then moves to the other side to start the next cycle, with the left and right chambers working alternately.
