Показаны преимущества и особенности вертикального вакуум-аппарата непрерывного действия VKT, а также возможности по увеличению эффективности работы продуктового отделения сахарных заводов. Благодаря специальной конструкции кристаллизационных камер, низкому уровню утфеля над греющей камерой и применению механических мешалок в каждой камере аппарат VKT может без затруднений работать с очень малой разностью температур между греющим паром и утфелем, а также с абсолютным давлением греющего пара значительно ниже 1 бар. При оптимальном использовании вакуум-аппаратов VKT могут быть реализованы самые различные энергосберегающие схемы, напримар, испарение с двойным эффектом в кристаллизационном отделении. Часть вторичного пара кристаллизации используется для обогрева одного из аппаратов VKT, что позволяет сэкономить идущий на эти цели греющий пар выпарной установки. При увеличении производительности сахарного завода возможно быстрое оснащение аппарата VKT дополнительной камерой. Аппарат работает непрерывно в течение всего сезона, в особенности с продуктами чистотой утфеля более 94 %. Очистка камер производится без остановки всего аппарата. Уваривание утфелей всех ступеней кристаллизации в аппаратах VKT обеспечивает равномерный режим работы продуктового отделения, позволяет добиться увеличения выхода сахара и способствует сокращению расхода пара на заводе.</p></abstract><trans-abstract xml:lang="en"><p>The article discusses the concepts of continuous vacuum apparatus operation: vertical VKT (VKT – Verdampfungs-Kristallisations-Turm) and horizontal cascade of VKH vacuum apparatus (VKH —horizontal vacuum pan) from BMA (Germany). The advantages and features of the vertical continuous vacuum apparatus VKT are shown, as well as the possibilities for increasing the efficiency of the product department of sugar factories. Thanks to the special design of the crystallization chambers, the low massecuite level above the heating chamber and the use of mechanical stirrers in each chamber, the VKT apparatus can operate without difficulty with a very small temperature difference between heating steam and massecuite, as well as with an absolute heating steam pressure well below 1 bar. With optimal use of VKT vacuum apparatus, a variety of energy-saving schemes can be implemented, for example, double-effect evaporation in the crystallization section. Part of the secondary crystallization steam is used to heat one of the VKT units, which saves the heating steam of the evaporator unit used for this purpose. With an increase in the productivity of the sugar factory, it is possible to quickly equip the VKT apparatus with an additional chamber. The device works continuously throughout the season, especially with products with massecuite purity of more than 94%. The chambers are cleaned without stopping the entire apparatus. The boiling of massecuite of all stages of crystallization in VKT devices ensures a uniform operating mode of the food compartment, allows to achieve an increase in sugar yield and helps to reduce steam consumption at the plant.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вакуум-аппарат</kwd><kwd>кристаллизация</kwd><kwd>утфель</kwd><kwd>сахар</kwd><kwd>сахарное производство</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vacuum apparatus</kwd><kwd>crystallization</kwd><kwd>massecuite</kwd><kwd>sugar</kwd><kwd>sugar production</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Петров С.М., Подгорнова Н.М., Тужилкин В.И., Филатов С.Л.
