Abstract

U diplomskom radu prikazane su karakteristike soka od naranče i procesa prerade. Navedena je i opisana karakteristična oprema koja se koristi u procesu ugušćivanja (uparivanja, koncentracije) narančinog soka. Proveden je potpuni termodinamički proračun višestupanjskog postrojenja za koncentraciju soka od naranče s početne koncentracije 12% na konačnu koncentraciju 60%. Proračunata su sva četiri stupnja uparivanja, termokompresor, dva predgrijača, pasterizator i kondenzator. Proračunate su potrebne ogrjevne površine uparivačkih stupnjeva te je proveden proračun čvrstoće posljednjeg uparivačkog stupnja. U prilogu rada nalaze se tehnički crteži posljednjeg stupnja uparivanja i izrađena procesno-instrumentacijska shema postrojenja (P&ID)

Abstract (english)

As part of the master's thesis, the characteristics of orange juice and orange juice evaporation process are given. Various equipment used in the evaporation process is described. A complete thermodynamic calculation of a multiple-effect orange juice evaporation plant used for concentrating orange juice from 12% to 60% is conducted. This includes: four falling film evaporators, an ejector (thermocompressor), two juice preheaters, a pasteurizer and a condenser. Heat transfer calculations which result in the required surfaces for heat exchange in the evaporators are shown, alongside a stress calculation of the final evaporator stage. In the appendix, engineering drawings of the final effect evaporator and the P&ID of the plant are given.
