TOMSK, Oct 11 – RIA Tomsk. Scientists of Tomsk State University of Control Systems and Radioelectronics (TUSUR) found a method of conversion of sapropel, in case of which all useful properties of raw materials remain; use of the technology will also facilitate transportation of the product, the press service of the higher education institution reports on Tuesday.
It is specified that sapropel (oozy deposits of the rotted-through remaining balance of plants and animals at the bottom of lakes. - Editor) contains a large amount of vitamins, acids, minerals and is used in medicine and agricultural industry. Its inventories are big, however transportation of raw materials is too expensive, and conversion on the available technologies does not allow to keep all useful substances. It is impossible to create an artificial analog.It is noted that the firm basis of sapropel is the meal, received by drying, when heating or with chemical impact loses a part of useful substances, which collapse or evaporate together with moisture. TUSUR scientists suggested to work with sapropel at low temperatures and to receive at the same time two products – meal and liquid concentrate.
"Sapropel is placed in the special cell with the rarefied air where boiling occurs already at the temperature of 30 - 40 degrees. The evaporated moisture is caught and concentrates. The technology allows to reduce amounts several times and to cut down expenses on transportation. At the same time useful properties remain almost completely", – it is said in the message.
It is added that now the scientists together with the industrial partner study the project of creation of the automated technological complex on production of sapropel concentrate on the basis of TUSUR's innovative technology.
