Hydrodynamics and heat exchange in the vacuum pans in sugar industry
(1977) Garyazha, Vladimir; Artyuhov, Yuri; Pavelko, Vladimir; Kulinchenko, Vitaliy
The efficiency of vacuum pans in the sugar industry depends on the intensity of heat exchange and on sugar massecuite circulation. The variety of the existing models-and the development of new- designs of these apparatus require an universal method for technological, thermal and hydrodynamical calculations. For this purpose some hydrodynamical and thermal regularities in the flow of massecuite and gas massecuite mixture in vertical pipes and during massecuite boiling in great amounts were investigated. The experiments were performed in a vast range of variations of working conditions and massecuite thermophysical characteristics. The relationships obtained permit to analyze the operation of the existing models and to design optimal construction elements for new vacuum pans; moreover, they enabled to develop the optimization methods and intensification processes for massecuite boiling.
Intensification of heat and hydrooynamic processes in industrial vacuum pans
(1978) Garyazha, Vladimir; Artyuhov, Yuri; Didushko, Boris; Kulinchenko, Vitaliy
New methods of intensification of these processes hare been developed here purely in hydrodynamic ways: a) by the way of blowing gas into boiling tubes of vacuum pans; b) by the way of localisation of thorough boiling of massecuite in a layer of small thickness, gravitatingly flowing along the plane inclined heating surface.
Investigation in the field of intensification of mass transfer processes in vacuum pans
(1978) Garyazha, Vladimir; Artyuhov, Yuri; Kulinchenko, Vitaliy; Didushko, Boris
On the basis of investigations in the field of hydrodynamics and heat exchange during boiling of massecuite in tubes a new hydrodynamic methods of intensified mass exchange while crystallisation by the way of blowing gas, steam or their mixture into boiling tubes of vacuum pans have been developed.
Investigation of intensification of mass transfer process in vacuum crystallizers
(1975) Garyazha, Vladimir; Artyuhov, Yuri; Kulinchenko, Vitaliy; Didushko, Boris
The methods of mass transfer intensification in vacuum crystallizers by vapour blowing into boiling tubas and also fey massecuite boiling in a small thickness gravity flow have been investigated. The results of testing of a vacuum apparatus with the device for vapour blowing-in during B- and C-maassecuites boiling are tabulated. The comparison of data on mass transfer velocity in conventional circulation vacuum apparatus and an apparatus with flat inclined heating areas is given. Досліджені методи інтенсифікації масопередачі у вакуумкристалізаторі, що досягаються вдуванням пари у кипятильні труби, а також рухом гравітаційно стікаючого киплячого утфеля в тонкому шарі.
