Complex potato processing for starch and by-products on the base of hydrocyclones

The article discusses the technical characteristics of potato starch processing equipment produced at the All-Russian Research Institute of Starch and Processing of Starch-containing Raw Materials - branch of the FSBSI «Federal Potato Research Center named after A.G. Lorkh» based on hydrocyclone installations with a capacity of 10 to 500 tons of potato processing per day. Hydrocyclone installations provide starch extraction directly from finely ground potatoes (potato porridge) to produce dry potato starch according to GOST R 53876 - 2010 «Potato starch» and a by-product - a mixture of potato fiber (pulp) and potato juice. The scope of application, technologies for the utilization of potato pulp and potato juice for animal husbandry and fertilizer irrigation, taking into account their chemical composition, are considered. The production facilities of the presented equipment can also be used for processing substandard potatoes, as well as by-products of potato production. It is noted that one of the reasons for the insufficient production of potato starch is the lack of a profitable raw material base in the country, since tubers are processed of poor quality at a high price. To ensure the economic efficiency of potato starch production, the starchiness of potatoes should be at least 19%.Thus, the main direction of increasing the efficiency of processing into starch is to increase the starchiness and yield of tubers. In addition, one of the reserves for an additional increase in potato starch output is the use of production facilities for processing substandard potatoes, as well as by-products of potato production. It was also noted that in order to increase the profitability of potato starch production, it is necessary to create enterprises with greater production capacity, as well as organize the production of modified potato starches with increased consumer demand.
