Bioethanol Process Trainer | RVX 126
The Bioethanol Process Trainer RVX 126 demonstrates three-stage bioethanol production through mashing, fermentation, and distillation processes. This bioethanol process trainer features stainless steel mash and fermentation tanks with enzyme and yeast addition, hot water jacket heating, CO2 monitoring, and borosilicate glass distillation unit with Vigreux column and Liebig-West condenser. Integrated pH, temperature, and CO2 measurement for complete process analysis.
The Bioethanol Process Trainer RVX 126 is an educational apparatus for studying bioethanol production through mashing, fermentation, and distillation processes. This bioethanol process trainer enables investigation of liquefaction, saccharification, fermentation, and distillation stages from raw materials to ethanol conversion on laboratory scale.
Product Overview
The RVX 126 bioethanol process trainer consists of three main components: stainless steel mash tank with enzyme addition capability, fermentation tank with yeast fermentation monitoring, and borosilicate glass distillation unit. Mash tank converts starch to glucose through alpha-amylase and glucoamylase enzyme addition with pH control via acid and base circuits. Temperature sensors and pH meter monitor mash properties. Fermentation tank receives mashed solution and converts sugars to ethanol and CO2 via yeast addition, with CO2 concentration measurement and temperature monitoring. Both tanks heat indirectly through hot water jackets with integrated thermostatic bath and circulation pump. Distillation unit includes 5L reactor flask with 1500W heating mantle, Vigreux distillation column, Liebig-West condenser, cold finger dephlegmator, and decanting funnel. Two centrifugal pumps transfer solutions between stages. Motorized valves control hot water flow. Electronic console displays temperature, pH, and CO2 measurements. Optional LABVIEW DAQ software transmits sensor data to PC.

Construction and Design
The Bioethanol Process Trainer RVX 126 features anodized aluminum structure with painted steel and HDF panels. Stainless steel construction includes mash tank with upper inlet for enzyme addition and inclined base for gravity drainage. Fermentation tank mirrors mash tank design with yeast addition capability and inclined drain port. Borosilicate glass distillation unit includes 5L reactor flask with Vigreux column, Liebig-West condenser, and cold finger dephlegmator. Sight glasses on both fermentation and mash tanks enable process observation. Nine K-type temperature sensors monitor critical points throughout all three stages. Hot water circulation system with thermostatic bath and pump maintains indirect heating for both fermentation and mash tanks. Two centrifugal pumps transfer solutions between stages with directional valve backwashing capability. Two peristaltic pumps introduce acid and base solutions. Electronic console consolidates all control switches, digital displays, and monitoring instruments. Mobile wheels facilitate relocation.
