Technical-technological design for chestnut processing and chestnut puree production

Europski kesten (Castanea sativa Mill.) je rasprostranjen na području Hrvatske na mjestima srednje nadmorske visine te na područjima gdje prevladava kiselo tlo. Kesten kao namirnica odgovara trenutnim potrebama potrošača koji teže konzumaciji biološki aktivnim tvarima, a koje su osnove zdrave prehrane. Cilj ovog rada je izrada elaborata tehničko-tehnološkog rješenja pogona za preradu kestena te je opisan tehnološki postupak proizvodnje kesten pirea. Tehnološki opis proizvodnje prikazan je tekstualno i pomoću blok-shema uz potrebne strojeve i tehnološku opremu. S obzirom na zahtjeve proizvodnje određena je makrolokacija i mikrolokacija te ukupna materijalna i energetska bilanca. Efikasnost, ekonomičnost i visoko higijensko-sanitarni nivo postignuti su sprječavanjem mogućnosti križanja putova te kontakta proizvodnog i neproizvodnog osoblja.The European chestnut (Castanea sativa Mill.) is found in the area of Croatia at mid altitude sites and in areas where acidic soil prevails. Chestnut as a foodstuff responds to the current needs of consumers who seek to consume biologically active substances which are the basis for healthy eating. The aim of this paper is to develop a study of the technical-technological solution of the chestnut processing plant and describe the technological procedure for the production of chestnut puree. The technological description of the production is shown in textual form and block diagram together with the list of necessary machinery and technological equipment. Macrolocation, microlocation, total material and energy balance, were determined according to the production requirements. Efficiency, economy and high level of hygiene and sanitation were achieved by preventing the possibility of cross-contamination and the contact of production and non-production personnel
