Description

This working, controlled & operated, semi-continuous process unit produces bio-ethanol, and provides for an in-depth, hands-on understanding of the basic, the practical & the theoretical crushing (grinding mill), fermentation & evaporation process.

The unit allows the student to experience and operate a continuous or a batch process like crushing, fermentation & evaporation (to concentrate the bioethanol after Fermentation) and modify the variables upon which it is based. It depicts the dynamic behavior of a production of Bioethanol as it is operated by the instructor and/or a student.

  • Bioethanol is produced from different sources: corn, sugar (cane sugar), several fruits or starch.
  • This unit in reduction is used as the primary medium, based on their well-known physical properties and safety considerations.
  • The unit can be used manually, controlled directed by the control panel, with or not a touch screen or a computer outside the area.
  • Temperatures, pressure, drop pressure & flow can be controlled & measured.
  • A variety of additional safeguards are provided to avert the possibility of unwanted ignition, or exposure to vapours. A safety valve is designed so that the unit cannot be over pressurized and to prevent unintentional vapour loss to the atmosphere. A heat protection device activaties a relay to provide an automatic temperature shut off in the event of overheating. An industrial grade control panel with emergency safety disconnects and provision for lock-out/tag-out is also provided.
  • The training aid incorporates a stainless steel fermenter with lid & trap, a glass boring distillation unit, which enhance the visual experience of the fermentation & the distillation processes under semi-continuous operation.
  • This unit could be coupled with a pervaporation unit to produce up to 95% of bioethanol.

Study of the production of bio-ethanol with three steps:

  • Pretreatment:
    • Reduction 30min
    • Liquefaction: reduction dextrins 1h
    • Saccharification: production of glucose and maltose 2h
  • Fermentation: 24h treatment
  • Distillation: separation of bioethanol

Proposed experiments:

  • Primary operation and experiment outline:
  • Review of a fermentation & regeneration process P&ID
