Preparation of tubers and cassava chips

The cassava is an interesting raw material for the alcohol production in a lot of African, Asian, South American countries.
Maguin, whose core business is the cleaning of tubers, offers efficient solutions for cassava preparation whether in the form of tubers or dried chips.
The expertise of Maguin in this field is the warranty of a perfect elimination of the tare (sand, stones, silt and various wastes). Indeed, the efficient elimination of sand is a particularly important issue for avoiding a lot of maintenance expenses and production losses resulting to the wear and premature aging of equipment of the line of alcohol production.

Preparation of tubers of cassava

The experience of Maguin, worldwide leader in sugar beet treatment harvested on clay and moist soils has been extended to different types of tubers (potatoes, chicory…).
The excellence of Maguin technology consists of a gentle treatment of roots, ensuring the integrity of tubers in order to protect the starch contained in the raw material. The using of a very low quantity of water enables to respect the environmental constraints and to reduce significantly the quantity of effluent water to be treated.

Preparation of cassava chips

In the Maguin process for the preparation of the cassava chips, the elimination of the tare (sand, stones, limon and various wastes) is particularly efficient: the process coming from an R&D program and the first industrial unit has been realized in 2010 in Thaïland for the production of 200,000 t/d of alcohol from chips. The innovating process of Maguin is a wet process for preparing a slurry of rasped chips without sand and without losing the starch of the fines particles which are present in significant quantities in the chips.


  • No liquid effluent
  • An adaptation to the different qualities of chips enabling to operate with chips at low cost containing a significant quantity of fines particules
  • A guaranteed efficient of sand separation
  • The absence of dust production avoiding all risk of explosion and all danger for human healthy
  • A wet rasping of chips avoiding all thermic alteration of the starch. Moreover the same rasps can be used for cassava tubers as an alternative raw material


  • Capacity from 200 t/d of cassava chips or 80 m3 of alcohol per day
  • Wet process
  • Stainless steel equipment
  • Fibers treatment to avoid the clogging of plate exchangers and the trays of the distillation column
