A manufacturer of machines used in the confectionery industry was looking for a new insulated machine casing for cooling confection productions.
Innclose was asked to create a design and construct the casing for a cooling tunnel which could be assembled quickly. In order to optimise air circulation, the inner surface of the casing had to be completely smooth. The following requirements were established:
- the design had to be created in 3D because this helps to prevent errors and delays, and because the customer only works in 3D;
- both the inside (for optimum air flow) and outside (for a nice, streamlined appearance) of the tunnel had to be smooth;
- the tunnel had to be constructed in 2 parts, so the machine could be transported to an international location by container;
- for hygiene reasons, the casing had to be easy to clean and any risk of sealant residues falling into finished products had to be eliminated.
Innclose created a 3D design. Once the design had been approved, Innclose constructed a tunnel using insulated panels featuring a rubber connection profile. This meant it was unnecessary to use sealant. Innclose designed a stainless steel door frame, where the doors were completely flush with the inside and outside of the wall panels. The mitres of the frame were also hygienically welded. The doors featured 3D-adjustable hinges, which mean doors can be adjusted and fit perfectly. The centre of the tunnel features a connection joint, which means the machine can be split into two and transported anywhere in the world.
Innclose installed the cooling tunnel at the machine constructor's premises, who then assembled the whole machine in China. The design fulfilled all expectations and also complied with all hygiene-related requirements. The insulating shell is completely flush with the machine frame. The casing also has a modern and streamlined appearance. Innclose is able to supply this casing in various wall thicknesses for cooling, drying and pasteurisation up to 120 degrees Celsius.
