The latest development in Confitech research is a compact and modular Vacuum Expansion Tunnel. The newly patented VXP.300 is conceived to be connected to existing hard candy forming lines to produce light and crispy candy suitable to be chocolate or sugar coated. Right after die forming, candies enter the expansion unit under vacuum where they increase their volume, then proceed along the cooling vacuum tubes until they reach the final temperature. Along the whole process the product is continuously kept in motion to allow a more homogenous and effective cooling while preventing sticking or deforming.

VXP.300

The latest development in Confitech research is a compact and modular Vacuum Expansion Unit designed to produce light and crispy candy suitable to be chocolate coated. The newly patented VXP.300 is conceived to be connected to an existing hard candy forming line. The VXP.300 is composed of an expansion unit and a series of modular cooling vacuum tubes. In the vacuum chamber the just formed candies increase their volume. In the cooling sectors the puffed candies reach the final required temperature. Along the whole process the product is continuously gentle kept in motion to obtain a homogenous and effective cooling while preventing sticking or deforming. Rotary valves at inlet and outlet points of the system ensure vacuum consistency. Two or more powerful vacuum pumps provide the required vacuum level along the entire system. The modular composition of the units allows to configure the system according to available layout minimizing the floor area required.
