green fig, a fruit usually consumed as dried is one of the important non-oil export agricultural commodities of iran. physical properties of green fig are vital parameters as regards the design of such post harvest processing equipments as dryers, sorters and storing chambers. in this research work the effect of moisture content on fruit characteristic dimensions, geometric mean diameter, spher...

The potential of Near Infrared Reflectance Spectroscopy (NIRS) as a fast method to predict the Crude Protein (CP) and Moisture (M) content in fishmeal by scanning spectra between 1000 and 2500 nm using multivariate regression technique based on Partial Least Squares (PLS) was evaluated. The coefficient of determination in calibration (R2C) and Standard Error of Calibra...

water is one of the most vital constituents in plants. in this research, for an estimation of leaf moisture content, the variation of capacitance was employed. the variations were measured via designed and manufactured capacitive sensors. the objective of the research was to estimate leaf moisture content by measuring its capacitance for five agronomic crops. experiments for measuring leaf capa...

to design equipment and facilities to dry, preserve and process pomegranates, it is necessary to know their specific heat and thermal conductivity. the objectives of this study were to determine the specific heat and thermal conductivity of pomegranates and develop mathematical estimation models for them. the effects of moisture content (15-75% w.b.) and temperature (5-20°c) on the thermal prop...

Litter moisture contents vary greatly between and within practical poultry barns. The current experiment was designed to measure the effects of 8 different dietary characteristics on litter and excreta moisture content. Additionally, free water content and water activity of the excreta and litter were evaluated as additional quality measures. The dietary treatments consisted of nonstarch polysa...

some physical attributes of two common types of iranian garlic cloves (white and pink) were identified and compared. a machine vision system was used to determine three di-mensions and both major and minor projected areas of garlic cloves at a moisture content of 42.4% w. b. the geometric mean diameter and sphericity were calculated, as well as the unit mass and volume of cloves were measured. ...

Ethyl formate (EF) was studied as a fumigant agent with the objective to replace methyl bromide (MB) for date fruit disinfestations. Date fruits Phoenix dactylifera 'Deglet Nour' with different initial moisture content (16% for dry dates, 20% for semidry dates, and a mixture of the two types) were separately fumigated with EF at different concentrations: 28.6, 57.3, 85.9, and 114.6 g/m3 for 2 h...

paddy de-awning using a de-awner increases the uniformity and flow rate of paddy grains through the orifices of hoppers, bucket elevators and chutes. in this study the effects of paddy variety, rotational blade speed and moisture content on performance of a prototype de-awner machine were investigated. the experiment was conducted in a factorial design with three factors, variety (hashemi and b...

A technique based on microwave sensing technologies has been developed which provides a means of estimating the average moisture content across a stack of timber during kiln drying. The microwave sensor, which comprises of a linear array of slots excited from both ends, was developed and trialed under a range of standard commercial kiln drying schedules using 100mm x 50mm Pinus radiata sample b...

the friction properties of granular materials play an important role in the determination of specifications for designing hoppers, transporting passages, dryers, silos and machines through which grain flows. in this study, the angle of repose and internal friction coefficient were determined for three common wheat varieties (sardary, gaspard and saysoter) at four moisture contents (12, 15, 18, ...
