This article analysis of drying agent’s spreading in ventilated drying of stem type agricultural crops and vegetable seeds, through which it aims to produce more and more high-quality products. The similar drying was not observed in different parts of the crops in ventilated drying, some parts of the drying product were dried out but some parts not dried well. The aims of the paper study this process. Therefore, products must be placed in the dryer with the thickness to have each point dry at the same time. Based on the practical experience of this criterion, the determination of loading thickness in drying was carried out theoretical analysis by using analytical dependencies. Theoretical analysis and analytical dependencies allow determining dimensions of the stack, layer thickness
The process of washing fruits and vegetables is considered. Stages of the process of washing fruits and vegetables. The theory of moisture penetration. Experimental studies of the process of saturation of pollution with moisture. The results of theoretical and experimental studies of the process of saturation of pollution with moisture are analyzed.
This article presents an analysis of the creation of a unit for drying stem agricultural crops and justification of its main parameters, which is aimed at growing large and high-quality products through this process. The purpose of creating such unit and justification of its parameters was that during drying, products were dried unevenly, resulting in some parts of the product were dried more than necessary, and some areas rotted without complete drying. Therefore, the shape of unit for drying products must be such that the product simultaneously dries. Based on theoretical and experimental studies on this criterion, was developed a nomogram, the shape and parameters of the dryer device were theoretically analyzed by using analytical dependencies
The article describes a calculation algorithm for modeling the process of washing the fruit, which allows you to change the parameters of the device in order to assess the quantitative change in the intensity of the mechanical interaction of the working body on the fruit surface. Parameters of the fruit washing machine, determined by the criterion the intensity of the mechanical interaction of the working bodies with the fruits When designing a machine, it is desirable to provide such process conditions under which the fetus makes 5 - 7 complete revolutions around its axis. This parameter is adjusted by changing the distance between brush cylinders, as well as the selection of parameters that provide the average value of the angular velocity of rotation of the fetus around its axis in within ωpl = 0.5 - 0.7 rad/s.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
