Vacuum crystallizer

for food

Our portfolio includes the engineering, specification, calculation, and production of boiling devices in accordance with the European Pressure Vessel Directive (PVD) 2014/68/EC and the German regulations for the specification and manufacture of pressure vessels AD 2000-HP0. We create inspection-capable CAD drawings, welding instructions, welding specifications, inspection plans and the relevant documentation in the desired language. This includes inspection reports, manufacturing drawings, manuals, risk assessments, declarations of conformity, material certificates, transfers of identification, pressure tests, process inspections and all other required acceptance documents. We also conduct non-destructive testing on pressure vessels. Buckau-Wolf Vacuum Pans are equipped with patented honeycomb calandrias. These calandrias consist of pipes that are welded in a honeycomb pattern without a pipe bottom (pipe plate). This minimises the distance between plates and optimises the heating surface ratio. A central circulation pipe and the stirrer ensure optimal mixing and a directed flow in the device and ensure a homogeneous suspension as well as intensive exchange of heat and micro-volume mixing. The result is a better crystalline structure at a significantly reduced boiling time. Summary • Recognised throughout the world for their high level of efficiency and top-quality sugar crystal • Retrofit to existing systems at any time • 25 % more heating surface for the same installation space in comparison to conventional pipe heating chambers • 75% reduction of depositing surfaces on the top side of the chamber
