mazafati date is a wet and semi-dried date fruit type with dark red to black color that has premier quality. because of its high moisture content, date fruits of this variety are very perishable at room temperature and therefore must be refrigerated during storage. in this study, effect of air temperature (50, 60, 70, 80 and 90 ˚c) and air flow rate (1, 1.5 and 2 m/s) in hot air drying of mazaf...

The drying kinetics of hawthorn in a pilot-scale experimental fluidized bed dryer with and without vibration was investigated. The effect of operating parameters, such as vibration intensity, drying air flow rate, and temperature, on the drying rate and shrinkage of hawthorn was studied. The hawthorn fruit was dried at various drying air temperatures ranging from 40-70oC and drying air volume f...

the effects of a couple of factors (cooking period of wheat: 0, 1 and 3.5 h and temperature of drying 70, 80 and 90 ْc) on drying behavior of tarkhineh during hot-air drying has been investigated. tarkhineh pill samples with 8 cm diameter and 11 mm thickness were dried to 0.64(d.b). results showed that cooking of wheat led to higher water absorption of tarkhineh dough, while increased drying rat...

vacuum drying of salicornia herbacea l. was performed at different drying temperatures (50, 60, 70, and 80c) to evaluate the drying characteristics and the effect of drying temperatures on the quality of salicornia. as the drying temperature increased, the drying time decreased significantly (p< 0.05). the drying rate decreased with decrease in moisture content and increase in drying time. on ...

Intermittent drying is a satisfactory technique for drying of heat sensitive grains especially rough rice. This method consists of two separate stages applied intermittently: drying and tempering. In this work, intermittent drying of rough rice is investigated both theoretically and experimentally. In order to characterize this process; a multi-scale model consisting of macroscopic and microsco...

In this data article, laboratory experimental investigation results on drying kinetic properties: the drying temperature (T), drying air velocity (V) and dewatering time (Te), each of the factors has five levels, and the experiment was replicated three times and the output: drying rate and drying time obtained, were observed. The experiment was conducted at National Centre for Agricultural Mech...

Microwave drying technology has the potential for large production time and energy cost savings versus traditional vacuum drying methods for active pharmaceutical ingredient (API) applications. One of the most critical parameters in the drying process is the determination of the end point, usually at a specified moisture content. On-line mass spectrometry (MS) was used as a tool to monitor micr...

in this study thin layer drying of corn in a convective dryer was investigated at air temperatures of 50, 60 and 70ºc and air flow rates of 1, 1.4 and 1.8 kg min-1. experiments were performed in completely randomized design (crd). the effect of air temperature and flow rate on drying time, drying rate, effective diffusivity coefficient and activation energy were studied. results showed that the...
