Food, Sugar, & Starch
|
Eurodia / Ameridia has found many applications for its process
know-how in the food, sugar and starch industries by offering various
techniques to meet the separation goals of its customers. These
include electrodialysis with and without current reversal, ion exclusion
chromatography, microfiltration, nanofiltration, and ion exchange
resins. Again, our goal is to offer the optimum processes (technically
and economically) to our customers by combining these various techniques.
Electrodialysis:
Our expertise in electrodialysis is based on more than 40 plants
in operation worldwide in these industries. For a more detailed
description of the electrodialysis, please go to the Technologies
Section / Electrodialysis of this website.
Thanks to recent improvements in both the structure of anion-exchange
membranes and in the design of stacks, electrodialysis can be
considered as one of the technologies that can help improve the
cost effectiveness of sugar mills by: (i) controlling organic
fouling, (ii) operating at high temperature (up to 60°C), (iii)
reducing waste effluents and pollution load, (iv) improving sugar
yields, (v) reducing the volume of molasses, (vi) and saving capital
costs.
Operating results of a commercial plant in Europe commissioned in 1998 are presented below, along with a detailed material
balance.
Ion Exclusion Chromatography:
We have already supplied fifteen plants in Europe based on the Improve
Simulated Moving Bed Technology licensed by the Nippon Rensui
subsidiary of Mitsubishi Chemical Corporation. The first system
has been commissioned in 1998 to separate sugar. The others are used for polyols purification and enrichment. The second
was started in 1999 to separate polyols and the third is scheduled
in 2000 for the same application. For more details about the process
and some data about the performance of our first plant, please
go to the Technologies Section / Ion Exclusion Chromatography
Section of this website.
Microfiltration:
In the food, sugar, & starch industry, we are developing applications
for the very rugged sintered stainless steel ScepterŪ membranes
of Graver Technologies. Our first customer is a sugar mill in
Europe where these modules are used to clarify sugar juices.
For more information about the technology, please go to the Technologies
Section / Microfiltration of this website.
