Hygienic insulation for dairy processing

Pasteurisers & UHT plants: thermal insulation with a V4A jacket fitted precisely to plate heat exchangers, tubular heat exchangers and sterilisation lines. The cladding keeps inspection hatches and sensors cleanly accessible without creating hygiene weak points. On UHT lines with medium temperatures above 135 °C we choose mineral wool in precisely fitted formed parts that follow the flow geometry, so that neither pressure nor vibration damages the insulation. Pasteuriser sections with alternating heating and cooling zones get transition details that separate each zone thermally and cleanly. We supply material certificates for V4A stainless steel and photo documentation of the cladding alignment: the basis for hygiene auditing and for the IFS or BRC certification of your plant. For extensive modernisations we coordinate with your plant builder and provide the insulation as a supply to final assembly, so that the works receives ready-to-install modules.

Raw milk tanks & storage vessels: cold insulation with a continuous vapour barrier on vertical and horizontal tanks. We prevent condensation on the jacket and protect the tank surface against corrosion. PUR/PIR rigid foam or mineral wool, depending on the required service life and the cleaning regime. Storage temperatures between 2 °C and 4 °C stay stable for years without energy losses or condensation. We finish the connection details at agitators, sampling points and cleaning accesses hygienically: no water-retaining zones, no bacterial nests, no gaps in which cleaning chemicals can remain. When tanks are replaced or added we coordinate with your dairy site manager and work between delivery cycles, so that ongoing milk processing is not affected. On request we also take on the survey and the thermal calculation as a preliminary service, before the tank is even in place.

Pipework & heat exchangers: prefabricated shells and formed parts for milk, water, brine and CIP lines. Cladding sheet in V2A or V4A, depending on the cleaning agents used. Connection details at pumps, valves and sampling points are finished hygienically, so that no gaps or cavities are created in which cleaning chemicals could remain. We calculate the insulation thickness from the medium temperature and the desired surface temperature: important so that contact protection values under the German accident insurance rules are met and energy losses minimised. For plate heat exchangers with frequent cleaning cycles we choose hood constructions that can be removed quickly and close tightly again after every CIP cycle without tools. Cladding joints are executed so that even aggressive cleaning media such as nitric acid do not attack the system.

Storage & filling: tank insulation in the filling area, hygienic jackets on the connecting lines to the packaging line. For extensions or conversions we work section by section, so that the production line does not come to a complete standstill. Transitions between cold and warm zones are handled with special details that resolve thermal bridges and prevent condensation. Where hygiene requirements are particularly strict, our cladding meets the applicable specifications, with documented processing in the separate stainless steel hall. On request we accompany commissioning with thermal imaging that proves the insulation as built matches the calculated values: important for audits, for energy consultants and for you as the operator. The work is agreed and documented on a project basis.
