Agitated Thin Film Evaporator

Listing ID #2670628

The typical Agitated Thin Film Evaporator consists of a tubular heat transfer area with an external heating jacket and a fast-revolving, inner rotor with flexible or rigid wiper elements. The driving speed is adapted to the product being handled, its particular specifications and task.
Key Advantages :

• Good heat conductivity (k-value), even when working with highly viscous and contaminated products Minimal thermal stress, thanks to low operating capacity, therefore a short dwell time (10-20 seconds of mean dwell time) No dead zone, therefore overheating prevented and perpetual high product quality guaranteed Continuous mechanical cleaning of the heating surface prevents incrustations High evaporation rates, due to highly turbulent film and large difference in temperature Gentle evaporation, due to short residence times, rapid conveyance in the heated zone and the constant product film renewal, happens often Combined with suppressed boiling points due to operation under vacuum Reduced need for maintenance because of sophisticated bearings and shaft sealing parts Shorter downtime and assembly time for maintenance and inspection No corrosion as outside surface is usually made of stainless steel Evaporation in one pass, no circulation Small film thickness, no hydrostatic height High turndown ratio and high flexibility for variation in requirements
• Low operating pressure down to 1 micron to reduced boiling temperature Single step drying because of unique designed combination of vertical and horizontal dryers Effective evaporation of concentrated slurries, heat sensitive products, viscous and fouling fluids up to 99% in a single pass Simple installation as the equipment is supplied skid mounted with all inter connecting piping, condensers and vacuum system Applications To concentrate highly viscous products, polluted liquids, salt solutions, oils, resins, etc As a sump evaporator for vacuum rectification columns Sludge drainage
