Drying data for individual rice kernels and bulk samples selected from various tillers of a plant and from different maturity groups were experimentally obtained. The data showed that over 93% of the drying occurred within 24 h of exposure to air at 40° C and 60% relative humidity. Differences in the equilibrium moisture content and drying rate constant among kernels were observed. Equilibrium ...

Freeze drying (FD) yields the best quality of dried sea cucumber but at the cost of long drying time and also the overall cost. Air drying (AD) gives an unacceptably poor quality product. To achieve faster drying along with a high quality product a microwave freeze drying (MFD) technique was developed to dry sea cucumbers. The relationship between corona discharge and microwave power at various...

tea is one of the most important medicinal plants which have a considerable effect on the treatment of cardiovascular disease and cancer. the drying process of tea leaves is carried out by hot air flow which consumes high level energy. the aim of the recent research was to investigate the procedure of high power ultrasound-assisted drying process of tea leaves. hybrid variety of chinese tea was...

By EXECUTIVE SUMMARY Hardwood lumber drying in the South is subject to hot and humid weather that promotes enzymatic stain in sapwood. Research has long studied the problem and certain remedies have been proposed. Chemical dipping is the most commonly used method of preventing enzymatic stain. However, its application is only topical and does not prevent stain. A private operator, Danny Elder o...

in this project, first we introduced a general rule for the design of drying processes and then, we have applied microsoft excel for this purpose. belt dryer is one of the most common dryers in the food industry. in this study, our aim was to process carrot by this dryer. we optimized the target function (total annual cost or tac) and investigated the influence of design variables on this targe...

The hypothesis tested in this study was that the self-etching system (Clearfil SE Bond, CSE) is less sensitive to surface moisture variability than the system that uses a separate acid-etching step (Single Bond, SB). Eighteen dentin specimens were bonded to composite using CSE or SB. Three different surface moisture conditions per bonding type (overwet, w; dry, d; and visibly moist, n [normal])...

MICs of clarithromycin and amoxycillin for 253 isolates of Helicobacter pylori were measured by an air-dried microplate method and compared with the results obtained by the agar plate dilution method. The air-dried microplate method is performed by coating each well of a 96-well microplate with the test antibiotic and air-drying it. There were no marked differences between the air-dried micropl...

The aim of this study was to evaluate the influence of ceramic surface treatments and silane drying temperature on the microtensile bond strength (µTBS) of a resin composite to a lithium disilicate ceramic. Twenty blocks (7x7x5 mm) of lithium disilicate-based hot-pressed ceramic were fabricated and randomly divided into 4 groups: G1: acid etching with 9.5% hydrofluoric acid for 20 s and drying ...

Drying is a common pharmaceutical process, whose potential to modify the final drug and/or dosage form properties is often underestimated. In the present study, pellets consisting of the matrix former calcium stearate (CaSt) incorporating the active pharmaceutical ingredient ibuprofen were prepared via wet extrusion and spheronization. Subsequent drying was performed by either desiccation, flui...

this study evaluated the use of the solar dryer at esfahan agricultural research center for drying prunes. a factorial experiment was carried using a randomized complete block design with four replications. the four methods used to accelerate prune drying were: control group (no treatment), mechanical perforation at one week of drying, blanching, submersion in australian cold dip method. the dr...
