There is a problem of ineffective usage of a significant part of the secondary resources formed as a result of industrial processing of agricultural raw materials that are usually wasted causing considerable damage to the environment.
Sugar production from sugar beet is a major source of secondary raw materials. With an average yield of sugar of 10-12% to the weight of the processed beet, about 83% of beet pulp, 5% of molasses, and 12% of filter sludge are formed, which can be used to produce a variety of valuable products. The main waste of sugar production is sugar beet pulp, which consists of leached-out beet slices having high humidity (90 ? 94) %. Beet pulp composition includes pectin, cellulose, hemicellulose, nitrogenous substances, ash, sugars. Granulated beet pulp was used for the studies to identify its composition and properties. Pectin was extracted from the pulp by means of acid hydrolysis. In order to increase the yield of pectin substances, pre-treatment of beet pulp in a vortex layer apparatus was carried out. The content of cellulose in the separated pellet was determined. Amount of biogas was measured that can be obtained by anaerobic fermentation of organic substances (43% of dry matter) remaining after separation of valuable components from the recycled waste. As a result of the conducted studies, a complex technology for processing large quantities of waste- sugar beet pulp with the production of valuable pectin, cellulose and biogas was proposed. |
