Proposal/Expertise: Elaboration of low-temperature methods for processing, refining and separation of the components in raw and waste materials of the foodstuff production with the use of completely new and ecological thermoelectric devices operating on the basis of Peltier and Zeebeck effect
Description of proposal or expertise:
New devices have been elaborated which allow to perform oriented crystallization and melting of ice in aqueous systems containing the components of the foodstuff products. Crystallization is performed from the surface of cold fingers introduced into the bulk of aqueous system.
In order to control the temperature of the cold fingers high-performance semiconductor thermoelectric converters were designed which akllow to set and check quite strictly the temperature in a wide range drom + 100 to – 30 C. As a result of multiple crystallization and melting a high efficiency of components separation is attained that makes it possible to purify, concentrate and extract them from original solutions in extremely clean ecological conditions. With the application of this technique power consumption is reduced while high-quality products can be obtained.
The proposed technique was tested in the laboratory environment. The ability of separation and refining was demonstrated for such substances as sucrose, amino acisa – glycine, lysine, phenylalanine, tyrosine and so on.
Problems to be solved and results:
The proposed method allow to perform ecologically clean processing of raw and waste materials of the foodstuff production and to extract biologically active components from the waste products.
