ATENG 11552 — Bioethanol Process Unit
Anodized aluminum frame and panels made of painted steel.
The unit includes wheels to facilitate its mobility.
Main metallic elements made of stainless steel.
Diagram in the front panel with distribution of the elements similar to the real one.
All the vessels, valves and other accessories in contact with process materials (except the
distillation unit) are made of stainless steel. The distillation unit is made of borosilicate
glass. Sight glasses are made of Neoceram glass.
- The “ATENG 11552” unit mainly consists of:
- Mash tank:
Cylindrical vessel made of stainless steel, with an inlet at the upper cover to load the
water, raw material and starch, jacket for process heating, stirrer and a sight glass
made of Neoceram.
ATENG 11552 detail
The base of the vessel is inclined slightly towards a port for draining the solution or
pumping it into the fermentation tank.
- Volume: 5 l.
- Fermentation tank:
Cylindrical vessel made of stainless steel with a jacket for process heating, stirrer and a sight glass made of Neoceram.
The vessel has a base inclined slightly towards a port for draining the solution or pumping it into the distillation unit.
- Volume: 5 l.
- Distillation unit:
Different elements made of borosilicate glass of high thermal and mechanical resistance, as well as perfect chemical inertia. It
- includes:
Heating mantle, 800 W.
- Reactor flask with discharge stopcock, volume: 5 l.
Reactor lid, with four inlets, especially designed for this system.
Vigreux type distillation column.
Stirring rod with stirring lock that assures a perfect insulation of the system.
Cold finger (dephlegmator).
Liebig-West condenser with interchangeable fittings.
Decantation funnel of 500 ml.
Temperature tappings placed at key points of the system.
- Two diaphragm pump to introduce the solution into the fermentation tank and the distillation unit, range: 0 – 3.8 l/min.
- Nine “J” type temperature sensors:
Two temperature sensors located at the mash tank to measure the temperature of the mash inside the tank and the temperature at
the outlet of the tank’s jacket.
Two temperature sensors located at the fermentation tank to measure the temperature of the preparation inside the tank and the
temperature at the outlet of the tank’s jacket.
Four temperature sensors located at different points of the distillation unit.
Temperature sensor located at the hot water circulation system.
pH meter measures the pH of the mash inside the mash tank.
- Hot water circulation system, including:
Pump.
Thermostatic bath.
- Acid/base circuit system, including:
- Two peristaltic pumps to introduce an acid or base solution into the mash tank, max. flow: 0 – 13 ml/min.
- Two vessels to contain the acid and base solutions, volume: 1 l.
- Seven valves:
Two needle valves are used to divert the hot water between the jacket of the mash tank and the jacket of the fermentation tank.
Two ball valves and two needle valves are used to drain the solution from the mash and fermentation tank or pump it into the
fermentation tank and distillation unit.
Ball valve is used to drain the water for hot water circulation system.
- Electronic console:
Metallic box.
Temperature sensor connectors. Digital display for the temperature sensors. Selector for the temperature sensors.
pH meter connector. Digital display for pH meter.
Three connectors for the stirrers. Three switches for the stirrers (one for the mash tank, other for the fermentation tank and another for
the distillation unit).
Five switches for the pumps (two for the peristaltic pumps, two for the diaphragm pumps and one for the pump of hot water circulation
system).
Two switches for the heating resistances (one for the thermostatic bath and another for the heating mantle).
Cables and accessories, for normal operation.
