After briefly recalling the main problems that arise in the study of globe valves for alternative pumps, a methodology has been set up in order to refine the design. The obtained method has the advantages of simplicity and independence from empirical diagrams. In summary, from the obtained equation, the suitable values of the parameters can be deduced, based on the assigned data (capacity Q0 and number of rounds n) of all the dimensions of the valve or of the valves. Depending on the parameter values, it is possible to identify the most suitable kind of valve: a single dish-shaped valve, a ring valve, a valve with several rings or a group of valves.

The purpose of this study was to compare two extraction processes for the\ud production of lemon liqueur (limoncello)—the traditional maceration of lemon\ud peels and a cyclically pressurized extraction process also known as rapid solid-liquid\ud dynamic extraction (RSLDE) that uses a Naviglio extractor. To evaluate the\ud extraction efficiency of the two processes, dry matter obtained by the evaporation of\ud the extracts was used to construct kinetics curves. The dry matter was directly\ud proportional to the amount of the active principle (terpenes) extracted and\ud consequently to the total concentration. Alcoholic extracts were analysed by gas\ud chromatography (GC) to monitor the extraction kinetics for major components of\ud the terpene fraction and for minor components of essential oils. Moreover, alcoholic\ud extracts were analysed by UV spectrophotometry to identify the more abundant\ud chemical species, while the organoleptic tests (i.e., a consumer test) performed on\ud the final product (limoncello) provided an indication of the taste of the final product\ud and revealed features undetectable with instrumental analytical techniques. To better\ud understand the phenomenon considered, a numerical simulation was performed to\ud evaluate and compare the matter flow of extractable compounds during the process
