Studying of technological characteristics of mixed varieties of paddy rice

V.I. Gospadinova, T.L. Korotenko, S.V. Demchenko

Results of studying of technological characteristics of mixed varieties of paddy rice in various percentage ratios are presented. It was found out that short grained varieties Rapan and Khazar have their technological characteristics worsened when mixed with each other in comparison with processing each variety separately. For varieties of the same type Liman and Garant it is appropriate to use varieties Rapan and Khazar as improving agents. The variety Liman, possessing low compared with other short grained varieties of technological and consumer properties, mixtures with them in different proportions significantly reduces their technological properties by reducing output of the whole kernel and increase the output of broken rice. On the other hand, the addition varieties Liman promotes decrease in cereal mixed nuclei with not separated germ. When short and medium grained varieties were mixed milling yield of head rice was lower. It can be explained because it is difficult to find optimal processing conditions for rice of different types. Medium grained variety Ametist can be used as improving agent when mixed with other varieties of the same type.

Keywords: rice, mixed varieties rice, technological characteristics of rice, milling yield, rice quality.

Yu.I. Molotilin, V.O. Gorodetskiy, N.M. Daisheva, S.O. Semenikhin

The process of extracting sucrose from beet cossettes in modern continuous extraction apparatus is not limited only diffusive mass exchange, due to the influence of the conveying device, it is supplemented by a partial pressing of the cossettes over the entire length of the apparatus. This partial pressing of beet cossettes in the apparatus, accompanied by mechanically mixing of displaced juice with extractant is similar to operating of diffusion apparatus with returning of pulp press water. It is obvious that the process of final mechanical desugaring of beet cossettes can be transferred to an external pressing of partly desugared by diffusion cossettes in pulp presses with following mandatory returning of pulp press water. In this case, pulp presses should be categorized as devices for final desugaring of beet cossettes and diffusion apparatus as one of the links in a unified complex for extraction of sucrose out of sugar beet, including: extraction of the main amount of sucrose by diffusion method, final desugaring by pressing of beet cossettes, preparation and returning of pulp press water. On the basis of the equation that takes into account the interrelation between the main technological factors of the extraction process with returning of pulp press water the nomograms were developed. These nomograms reflect the interrelation between sucrose content in the fresh pulp, amount of obtaining raw juice and sucrose losses in the pressed pulp, i.e. they are contribute to the solution of a number of practical issues related to improving the juice-obtaining station of a sugar factory work. It is also shown that the returning of pulp press water allows to solve the complex problem: reducing of the amount of obtaining raw juice in order to reduce the consumption of energy resources and reducing the production losses of sugar in the pressed pulp with a corresponding increasing of product yield.

Evaluation of quality parameters of quick lighted charcoal for hookah

E.A. Bubnov, E.A. Timoshenko, N.N. Vinevskaya

There is no tobacco burning process while smoking hookah and smoke is formed because of evaporation and further condensation of volatile compounds of hookah blend. The charcoal heats hookah blend to a certain temperature and therefore it is the main factor which affects the smoke formation. There are two main types of hookah charcoal: quick lighting and usual. Hookah charcoal is pressed briquettes or tablets of natural charcoal, and quick lighting tablets for acceleration their ignition properties are treated with saltpeter. Quality parameters for quick lighting hookah charcoal are not standardized, so we have suggested and defined parameters which affect the burning process. Tablets mass and their variation quotient, influence of quick lighting charcoal storage duration on burning time and temperature of exhausted gases have been studied. As the result it has been discovered that tablets mass can vary greatly and variation quotient is from 2 to 9%. Quick lighting hookah charcoal while stored in open pack adsorbs water vapors from ambient air this affects the process duration and its temperature. It has also been found that it is more difficult to ignite charcoal after storage in open pack. We have also determined that increasing storage duration leads to decreasing uniformity of charcoal properties and exhausted gases temperature. As the result measures for improving quality and leveling properties of quick lighting charcoal have been suggested.
