Experimental and Theoretical Study of Thompson Seedless Grapes Drying using Solar Evacuated Tube Collector with Force Convection Method
An evacuated tube solar collector drier is designed and developed to study analytically and experimentally drying kinetics of Thompson seedless grapes in Pune, India. Drying experiments are carried out in the month of April- June for continuous three years from 2013-2015. During the experimentation, temperatures of hot and cold air at various places, ambient relative humidity and humidity varia...
متن کاملinfluence of temperature, air velocity and pretreatments on drying thompson seedless grapes
drying is one of the most important steps in raisin processing. during this step, initial moisture content decreases up to 15-17% (db) for suitable storage. achieving optimum drying conditions can affect the processing time and improve raisin quality. temperature, air velocity and pretreatment are important factors in the quality of the grape drying process. in this research, the effect of temp...
متن کاملDegreening and Reducing Berry Shatter of Thompson Seedless Grapes by Using Safe Agricultural Chemicals
Berry color is one of the main fruit attributes that affect the marketability of Thompson seedless grapes. Yellowish berries are more desired by consumers especially at the beginning of the season. Consumers in many European countries have been demanding yellowish berries of “Thompson” seedless grapes. Ethrel was found to enhance the breakdown of chlorophylls and the formation of carotenes. How...
متن کاملFixed and Incremental Levels of Microwave Power Application on Drying Grapes under Vacuum
Microwave vacuum drying has been investigated as promising potential for high-quality dried fruits. In this study, a batch microwave vacuum dryer was used to understand the effect of levels of microwave power on the drying characteristics and moisture content of grapes. Thompson seedless grapes were treated 1st for 30, 60, and 90 min at fixed levels of 500, 750, 1000, 1250, and 1500 W at a redu...
متن کاملDrying of Matricaria recutita Flowers in Vibrofluidized Bed Dryer: Optimization of Drying Conditions Using Response Surface Methodology
Drying of Matricaria recutita flower was investigated experimentally in a VibroFluidized Bed Dryer (VFBD). The aim of the present work was to optimize the best operating conditions for the drying of Matricaria recutita flower in the VFBD based on experimental design techniques. Response Surface Methodology (RSM) and Central Composite Design (CCD) based on 4-variable with 5-level have been e...
