D. Babenko, N. Dotsenko, O. Gorbenko, N. Kim. Justification of the implementation of a separator of seeds of vegetable and melon crops as part of the technological line A modified design of a seed separator was tested in various technological configurations based on the technological line of separation seeds of vegetable and melon crops: with a serial separator, with an experimental separator, complete with a MOS-300 machine. The comparative characteristics of such indicators as productivity, seed loss, the content of impurities in seeds, injury to seeds are given. The implementation of the melon seeds separation into technological line is substantiated. Keywords: vegetable and melon crops, separator, technological line, seeds separation.

“…The prototype was evaluated at four different feed rates (20,30,40 and 50 kg/min), five drum speeds (3.25, 5.47, 6.98, 8.52 and 10.64 m/s) and four time intervals (0, 3, 6 and 9 days). The results showed that an increase in the speed of the crushing drum, a period of sowing melon seeds and a decrease in the feed rate tend to reduce the cleaning efficiency, where the maximum value of the cleaning efficiency was 88.83 % at a crushing drum speed of 10.64 m/s, a feed rate of 20 kg/min and sowing time for melon seeds 9 days after harvest [9]. An oil press for melon seeds was developed, an analysis was carried out and a conclusion was obtained when obtaining oil from melon seeds, the husk lowers the quality of the oil, without the husk the amount of oil decreases.…”

The object of the study is the fruits of melon. The problem is the crop that remains in the fields. The article provides an overview of technologies for the processing of melons, and studies of the authors are given. On the basis of these studies, technological schemes for the production and formulation of such products as jam, jam, confiture, blended juices, vegetable oil from melon seeds were proposed and justified. Optimal additives and ways of introducing pectin into them are determined. The presence in finished products of vitamins of group B, vitamin C, β-carotene, almost all essential amino acids, micro- and macroelements, the content of which does not noticeably decrease during storage under the optimal conditions established by us. Studies have been carried out on the selection of an extractant and the determination of the optimal parameters for extraction, isolation, neutralization and drying of pectin from melon peel. As a result, pectin was obtained with a degree of esterification of 67...69 %, a jelly-forming ability of more than 170 degrees of Tarr Baker, and a jelly strength of about 460 mm Hg

The analysis of literature sources shows that the production of seed material for vegetable and melon crops is one of the most important problems that exists in the field of agricultural processing. The production of cucumber and melon seeds is an urgent issue in view of the volume of their cultivation in Ukraine. To study the processes of fruit grinding and seed production in agriculture, the key parameters are the dynamic friction coefficient, the volume deformation coefficient and the static load coefficient, but existing methods and equipment are limited to determining the limit values of the indicators, not allowing a full study of the dynamics of changes in properties at different stages of the technological process. To solve this, it is proposed to develop new methods, in particular, the use of computer modelling, which will allow a more detailed study and optimisation of physical and mechanical properties and their changes. The aim of the article was to study the physical and mechanical properties of vegetable fruits, which have the greatest impact on the quality of the technological process of fruit seed grinding and preliminary seed extraction. The study was conducted in the problematic research laboratory of the Faculty of Engineering and Energy of Mykolaiv National Agrarian University. Experimental setups were used to determine the dynamic coefficient of friction of melon and cucumber seeds, a device for determining the initial density of seed fruits, and a device for determining the dependence of seed deformation on compressive load. Experimental data show that the most optimal values of the static coefficient of friction, depending on the type of surface, for cucumber and melon seeds are perforated sieves, the values of which are 0.75 and 0.85, respectively. Optimal values of dynamic friction coefficients for cucumber have a surface made of perforated sieve – 0.69 and for melon made of aluminium – 0.88. The dependence of the linear deformation of seed fruits on the specific pressure increases from 0.9 to 3.6. The values of fruit deformation from compressive load vary from 4.1 to 24.6. The research presented in the article is of practical importance and can be used in the field of agricultural production and in the development of new engineering solutions
