One of the important stages of growing seeds of agricultural crops is its post-harvest processing, which includes the drying process, is the main and one of the most effective methods for storing and processing agricultural raw materials. The use of vibration drying equipment is especially effective in high-tech processes taking place in the seed industry, where product moisture is the most important condition for the implementation of technology. The object of research in this article was the technological process of post-harvest processing of high-moisture pumpkin seeds, in particular drying. The purpose of the work was to analyze the current state of post-harvest processing of high-moisture pumpkin seeds and to establish promising methods and means for intensifying this process with a simultaneous increase in the quality of the final raw material obtained. The task of the work was: to review research and publications on the state of post-harvest processing of pumpkin seeds in Ukraine, to establish the features of its post-harvest dues, in particular drying, to get acquainted with the technical means and technologies for performing the technological process of drying pumpkin seeds, to establish the main disadvantages of the existing drying equipment, to determine and to propose new promising technologies and technical solutions for intensifying the drying process of pumpkin seeds with a simultaneous increase in the quality of the final raw material with minimal energy consumption and translate them into a developed model of a vibration dryer, which sequentially implements filtration and convection stages of drying. The research methodology was based on a review analysis of existing studies and publications on the state of post-harvest treatment of pumpkin seeds in Ukraine and the search for ways to intensify this process with a simultaneous increase in the quality of the final raw material obtained. In scientific work, based on the results of the study, it was found that the existing grain drying equipment does not meet the requirements for drying high-moisture pumpkin seeds, therefore there is a need for the development, research and implementation of energy-efficient schemes and structures. The existing samples of domestic equipment for post-harvest processing of high-moisture pumpkin seeds are morally and physically obsolete, do not provide flexibility in the execution of the technological process, are energy- and metal-intensive and cannot be used in processing lots of seed material. The proposed design of a vibrating dryer, which sequentially implements filtration and convection stages of drying pumpkin seeds. The developed installation provides an intensification of this process with minimal energy consumption while increasing the quality of the final raw material obtained.

Introduction. To represent our national goods at the Western market it is necessary to ensure, first of all, the competitiveness of local products through complex mechanization of technological processes, labour costs reduction, increasing yields and quality of received products. The aim of the research is to provide the comparative analysis of technology and machines for potato harvesting, to determine the main factors that influence the agricultural technical indicators of harvesting equipment, to develop technological process patterns and to examine the strategies for improving the potato root-and-harvest machines. Methods and methodology. The research was carried out on the basis of technological and constructional analysis of technology and machines for potato harvesting. The methods of comparison and mathematical modelling of technological processes were used in the study. The research studies of Ukrainian and foreign scientists on technology and machines for potato harvesting were used as information base of our paper. Results. A comparative analysis of technology and machines for potato harvesting made it possible to determine the main factors that influence the agricultural performance of harvesting machinery and to develop the technological process for a digger, a double-loader digger and a harvester (harvesting machines). A theoretical model of the technological processes of harvesting machines includes both uncontrolled and controlled factors that influence the choice of a potato harvesting technology of a digger, a double-loader digger and a harvester. Nevertheless, the first factors are connected, primarily, with the conditions of potato growth and its biological properties, and the second factors deal with the organizational and technical measures, including the improvement of the working bodies of machines (cutting, dirt digging through, top separation, longitudinal hump with cut roller and other constructive and kinematic parameters), quality of received products, length and terms of potato storage, available farming human resources, free vehicle in the period of harvesting, farm potato storage, farm equipment for potato cleaning and sorting.

Archaeological investigations of the Colline Metallifere district (Southern Tuscany, Italy) have highlighted several Medieval sites located close to the main Cu-Pb-Fe (Ag) ore occurrences. This study is focused on the investigation of late-medieval slags from Cugnano and Montieri sites using both geochemical and mineralogical methods to understand slag heterogeneities as result of ore differences and technological processes. Matte-rich slags present in both sites (with abundant matte ± speiss and frequent relict phases) represent waste products related to primary sulphide ore smelting to obtain a raw lead bullion. The distribution of slags between the Ca-rich or Fe-rich dominant composition, and the consequent mineralogy, are tracers of the different ore–gangue association that occurred in the two sites. Silver is present only in very small matte-rich slags and ores enclosed within the mortar of the Montieri site; wastes derived from silver-rich mineral charges were probably crushed for the recovery of silver. Matte-poor slags found at Montieri represent a second smelting; raw lead bullion obtained from matte slags (both Fe- and Ca-rich) was probably re-smelted, adding silica and Al2O3-phase-rich fluxes, under more oxidizing conditions to reduce metal impurities. This second step was probably employed for Zn-rich lead ores; this process helped to segregate zinc within slags and improve the quality of the metal.

Abstract. The objective of this study is the kinetics process of drying of the pears cv. Conference, cv. Abate and cv. Lucas with a laboratory dryer, in order to identify at which level of humidity the maximum speed of evaporation is achieved and at which level of temperature and humidity pears slices begin to change (colour and shape) and to determine which one of the three tested varieties offers the best properties for drying, which will ensure that the final product is technologically and organoleptically the most acceptable. Drying parameters were the same for all three varieties: 2 hours at air temperature 90oC, 2 hours at air temperature 80oC, 2 hours at air temperature 70 C and 2 hours at air temperature 60o C.  The results showed that the sample of the cv. Conference has undergone the least oxidation process, rounded edges and shriveled slices, and samples of the cv Lucas showed the worst results. Following the drying process of all three varieties, it can be concluded that the cultivars Abate and Conference achieved the lower evaporation speed, unlike the cv. Lucas. The cultivars Conference and Abate have attained consistent drying and in this way the technological process was finished with a smaller temperature, resulting in a better quality of the final product. o
