FARKLI KALINLIKLARDAKİ HAVUÇ DİLİMLERİNİN DONDURARAK KURUTULMASI
(2021-02-05) Janaani, Ahmed H.
In this study the carrots are dried by the method of freeze drying. Cut the carrots into circular slices, these circular slices were divided into two halves. The first section had a diameter of 5 mm and the other section was 7 mm. These slices were dried using a device SCANVAC COOLSAFE the weights of the carrot slices differed and for each weight and diameter we dried for two hours and using different temperatures. When evaluating, the amount of carrot slices for freeze-dried samples was observed that the dried samples were 5 times more than the amount of carrots. Weighing freeze-dried carrot slices during a total of 14 drying hours loss data were recorded. It was applied on 10 different mathematical models using the MATLAB program. The error analysis of the models at the result v was made using the estimated standard error (RMSE), chi-square (x2) and regression coefficients (R2) in the models used. According to the results, it was determined that the Page model was closer to the experimental results compared to the other models. Statistical error values found for samples; R2, x2, RMSE values respectively It was found to be 0.018565707 for 5 mm and 0.019532936 for 7 mm.
