Vessels and pipelines in the food and beverage industries must be constructed to withstand stringent cleaning and disinfecting. A maximum roughness (Ra) of 0,8 µm is often required in the component interior. Foil wrapped, cold-rolled sheet metal (2B) is used and the weld seams are tested for flaws and ground flush with the sheet metal surface in several steps.

A true LBF strength: finding and optimising technical solutions with our customers. Together with our customer’s ideas and our network of experience, we design products, provide services and complete projects. LBF can come aboard at any stage during a project – whether the solution is almost complete or if it is still unclear exactly what product is needed. Design sketches, brainstorming, sample productions, as well as taking measurements and testing all lead to finding a solution.

Aside from the standard duct system, special components are also needed in microchip facilities, such as silencers, multi-leaf dampers, or exhaust air collectors in tube form with diameters of several meters. These collectors are the key component of the exhaust air facility. This is where the exhaust air from all of the machines meets to then be redirected to the scrubber systems. If the collector fails, there will be a complete halt to production. The collectors must be statically calculated and designed; the maximum length of the single pieces is defined by the Halar-furnace measurements.

Freestanding exhaust air tower consisting of load-bearing rectangular collector ducts with side connecting ports, inspection openings, and above that a duct silencer and an outlet tube. The exhaust air tower was placed behind a filter system and blows the cleaned exhaust air straight up and out at a minimum speed and a requested distance from the structure, thereby quickly mixing the exhaust air with the ambient air.

A well planned logistics management is worth its weight in gold, especially on large construction sites. In coordination with the customer, the components are given customer position numbers, which have already been included in the assembly plans. If needed, the packages are marked with an identification tag allocating the correct place on the construction site where it is to be assembled. For international projects thorough packing lists for the entire scope of delivery can be compiled upon request. For the freight, LBF has access to standard trucks and trucks with special functions, including those with cranes for unloading or low loaders.

Rectangular industrial silencers with connecting pipe and exhaust stack for polluted air. The welded silencer casing is equipped with inspection doors and removable splitters. The splitters can be vacuumed and wiped clean. The steel construction carries the complete load of the structure also allowing for wind load. The stacks are equipped with platforms and measuring points for regulatory inspections.
