the drying behavior of green peas is investigated in a pilot scaled fluidized bed dryer (fbd) with inert particles assisted by an infra red (ir) heat source. the variation of shrinkage and moisture diffusivity with temperature and moisture content were investigated. the experimental drying curves were adjusted to the diffusion model of fick’s law for spherical particles. the result was that, al...
introduction drying foods, fruits and vegetables is a suitable method to reduce post-harvest losses of the crops. drying is considered as a simultaneous heat and mass transfer process. various physical, chemical and nutritional changes occur during drying of foods and are affected by a number of internal and external heat and mass transfer parameters. external parameters may include temperature...
Biomass, as a renewable source of energy, can be used in many industries to reduce their dependence on fossil fuels. However, due to the significantly high and varied moisture content of biomass, its use has several drawbacks, such as low total efficiency and process instability. Drying biomass before combustion or gasification can eliminate these drawbacks. Besides these benefits, there ar...
1- in a search directed to the reaction of compound)23(the cycloaddition reaction of 1,3- diphenylisobenzofurane)14(with p-benzoquinone)19(,followed by addition of cyclopentadiene was carried out.the specific spacial stracture of its ir,nmr,mass spectra. 2- in another attempt the kinetic stability and behavior of compounds)20(and)23(was studied.the main subject of this study was the highly reve...
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
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...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

abstract: proverbs are of the language materials which of the food of any language depends on the quality and quantity of these same materials. in the present research, the researcher tried to present the ramsarian proverbs according to four variables of color, fruit, plantsand animals that selected from the book of the members of each of these four variables, put them into the spss system fo...
rice is one of the most widely human consumed agricultural products. for a prevention or diminishing of rice cracking in its milling process, precision control of drying conditions is indispensable. in this research, a thin layer experimental dryer is employed to obtain paddy’s drying kinetics. drying experiments were conducted at five inlet temperatures of drying air of 30, 40, 50, 60 and 70 °...
