Modelling of thin layer drying kinetics of sour cherry in a solar dryer and under open sun
نویسنده
چکیده
Drying kinetics of sour cheery is investigated in solar dryer with forced convection and under open Sun with natural convection. Drying data were fitted to different mathematical models, whose performance was investigated by comparing coefficient (R), reduced chi-square (Ç) and root mean square error (RMSE) between the observed and predicted moisture ratios. Among these models, drying model developed by Midilli and Kucuk model showed good agreement with the data obtained from the experiments in the solar dryer with forced convection drying mode. Logarithmic model has shown a better fit to the experimental sour cherries data for open sun drying with natural convection mode than the other models.

Sun drying is a well-known food preservation technique that reduces the moisture contents of agricultural products. Shrinkage, rehydration ability and color of food materials during air drying adversely affect the quality of the dried products. Since all fresh tomatoes can not be consumed at the time of harvest, preservation provides a larger market, allowing consumers to buy the preserved toma...

Rice is only second to wheat as a major food for Iranians. It has to be dried for processing and/or storing due to excessive moisture content after harvesting. In most parts of Iran, rice is sun-dried by spreading it on the ground under solar radiation which leads to excessive losses such as attacking birds and rodents, grain contamination, wind and rainfall hazards, as well as thermal and mois...

In this paper, water content from celery, corn, and sour cherry were removed through tunnel, fluidized bed, and fluidized bed with microwave dryers. One day before performing the experiments, the fruits were put into a refrigerator and were ground into slices with average dimensions of 5×8×8 mm. For each experiment, 40 g of the samples were inserted in dryers. Moisture content in the samples wa...
