The interior components of silencers in the food industry must be accessible or removable to facilitate inspections, cleaning and disinfecting, or replacements. Absorbent surfaces can be fitted with foil so they can be vacuumed and wiped down. Careful cleaning with a steam cleaner is possible on stainless steel meshes. For smaller quantities of air, a round construction is usually technically and commercially the most economic design.

Reactive silencers are usually only made of sheet metal or stainless steel and do not contain mineral wool, because in specific industries porous materials are avoided for hygienic reasons. However, this also creates a larger construction. The advantage is that it can be completely cleaned with disinfectants or steam cleaned. The silencers pictured here are located on the roof of a manufacturer of a nut-cocoa-spread which causes sticky particles in the exhaust air.

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.

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.
