The unique process,“ Repeated batch fermentation ”• The origin of this process is J-alcoJalco’sethanol production plant.• This process has many merits,• Mechanical separation is not necessary.• Strong tolerance with bacteria• Easy to change the capacity of plant• High efficiency, Low operation cost.J-alco is a Leading company ofethanol business in Japan.The basic concept of thismolasses unique process and thespecial yeast B18 is supportedby J-alco.Repeated Batch ProcessFermentationStoragePropagationYeast can separate and recover by using it’s cohesive character.Yeast can be separated without any separation machine.9

Why you should chose us?• Yeast fermentation• Simple technology from ancient times.• On the other hand, it’s s a Deep science.• Special design with Brewerie‘sexperience.• Large scale fermentor, , Piping• Cleaning system, other equipments“Industrial aseptic concept”Why you should chose us?• The most important concept is“ Everything should be User-friendlyfriendly. “• Our view point is always on user side- Not only construction,- We can support all scene in project• Plenty of Know-How in fermentation10

In comparison with chemical plant• Special design for microorganism• Worker needs technical knowledge.• Manager should be quite familiarwith process theory .• It is very difficult to prepare thesestatus from beginning.Follow-upTrainingWhyfollow-up?up?• Improvement Management skill Operation skill Analysis skillTrainingmenu• Control skill for all of the facilities• How to check the condition of process• Review of analysis & measurement skill“Productivity has improved. ”13

Today’s s presentation• Molasses fermentation scope• Process description• Special features in our process• What is the “ cohesive yeast ” ,B18?• Follow-up TrainingT• The recent dataAssumption of design• Ethanol production :33,000kLyear (110kLday)• Yield : 85%• Repeat number of cycle : 8 times• Volume of fermentation liquid : 1,600kLkLcycle• Ethanol production after fermentation: 145tcycle14

The recent data of production• This graph is recent production.• Production (kL(kL/day) is “95105kL/day”11010090807060Production [ L Day]50 2008 year 2009 yearThese data was given by TRE.The recent data of fermentationYield• Almost trial could clear our target yield.(>85%)Repeat number, Volume of fermentation liquid• Target repeat number is 8 times (total volume:1600kL),and most of these trial could reach to 10 times.Target yield: >85%Target yield: >85%Target repeat number :Over 8times ( >1600kl) These data was given by TRE.This trial period is 4 months from January 2009.15
