Abstract

Izvedena je toplinska bilanca za hlađenje 1850 kg trešanja i 2420 kg bresaka, u rashladnoj komori, sa početne temperature 20°C na konačnih 0°C odnosno 2°C. Uzorci hlađenog voća imaju različitu održivost u rashladnim komorama. Na temperaturama od 0°C do 2°C uz prosječnu vlažnost od 90%, održivost trešanja je oko 14 dana, a bresaka od 14 do 42 dana. U toplinskom proračunu uzeti su u obzir svi procesni parametri i kvaliteta izolacije komore, koji utječu na ukupno toplinsko opterečenje.

Abstract (english)

The heat balance for chilling of 1850 kg cherrys and 2420 kg of peaches, from starting temperature of 20°C to finally 0°C or 2°C, in chilling chamber, was established. The samples of chilled fruits have different preservation capabilites in chilling chambers. At temperatures from 0°C to 2°C, with average relative humidity of 90%, duration of cherrys is about 2 weeks, and for peaches 2 to 4 weeks. In the heat balance calculation, all process parameters and quality of isolation, have been taken in to consideration.
