Large Scale Vacuum Freeze Dryer LLFD-B11 Download

Overview

Large Scale Vacuum Freeze Dryer LLFD-B11 is rectangular type, cylindrical compact structure. It offers manual and auto control mode, sensor calibration, intelligent temperature control, freeze drying termination reminding and other functions. The temperature ranges from -50℃ to +70℃ and offers 3+1 layers of shelf with 70 mm if shelf spacing and size of each shelf is 270 mm × 400 mm. Material used AISI 304 stainless steel, top and bottom plate thickness 5 mm. Features CFC Free refrigerant and PT-100 platinum resistance temperature sensor. Designed with refrigeration system, shelf, condenser, vacuum system and liquid circulation system. The heat is transferred to the inner space of the vacuum chamber and absorbed heat during sublimation efficiently. The product is dried completely and evenly.
