| Summary: | Rheological properties of beet chips are one of the main factors determining the effectiveness of its diffusion desugarization and subsequent pressing. The article presents the results of studies aimed at comparing the three most widely used industrial methods of extragent processing in terms of their influence on rheological properties of beet chips. It has been shown that distortion of sugared chips after ten-minute compression with a pressure of 0.16 kp/cm2 and a subsequent ten-minute relaxation after treatment with an extractant using sulfuric acid makes up 32.11% and 19.68% respectively, distortion of chips after processing with an extractant using sulfuric acid in mixtures with freshly prepared gypsum makes up 34.08% and 23.05%, and distortion of chips after treatment with an extractant using sulfuric anhydride - 36.81% and 25.25%. On the basis of the obtained data, the elastic moduli were calculated, which made up 79,72 kPa, 68.07 kPa and 62.15 kPa, respectively. Under production conditions, an increase in the content of dry substances in the pressed pulp can be about 3.30% when processed with an extractant using sulfuric anhydride, and about 2.87% when treated with an extractant with sulfuric acid in a mixture with freshly prepared gypsum through the achievement of optimal rheological properties of spent beet chips. |
