Microbial and Physicochemical Characteristics on Raw Cereal for Sunsik by Hot-air Drying Methods

Comparative study of three drying methods: freeze, hot air- assisted freeze and infrared-assisted freeze modes

The dehydration tests were conducted at three drying methods to evaluate the drying curves and the energy uptake. Apple (Malus domestica L.) cubes were dried under different processing conditions applying freeze drying (FD), freeze drying assisted by hot air and freeze drying assisted by infrared radiation. Control samples were produced using regular freeze drying without the pre-drying. Hot ai...

Mathematical Modeling of Hot Air Drying of Spinach Leaves in Universal Hot Air Oven

Drying Macadamia Nuts by Hot Air Combined with Microwaves as Compared to the Conventional Hot Air Process

optimization of drying process of parsley using the combination of hot air and microwave methods

in this study, parsley was dried using three drying methods: hot air (50, 60 ‎and 70 ºc), microwave (90, 180, 360, 600 and 900 w) and a combination of ‎hot air – microwave (60ºc and 360w). selection of the optimum levels for ‎drying in combination method took place with quality tests of dried ‎samples. the drying data of parsley with hot air and microwave methods ‎was fitted with eight models: ...

Drying kinetics and mathematical modeling of hot air drying of coconut coir pith

Drying kinetics of coir pith was studied and the properties of compressed coir pith discs were analyzed. Coir pith particles were oven dried in the range of temperatures from 100 to 240 °C and the rehydration ability of compressed coir pith was evaluated by finding the volume expansion. The optimum drying temperature was found to be 140 °C. Hot air drying was carried out to examine the drying k...
