Litchi (Litchi Chinensis Sonn.) is an important commercial fruit in Thailand and Vietnam. Litchi fruit is consumed both as fresh and dried products. Also most of the export of litchi is in the form of dried whole litchi fruit. Thermo-physical properties and drying model of litchi fruit is important ...

A two-dimensional finite element model was developed to simulate moisture diffusion in mango fruit during drying. The diffusivity and shrinkage of mango used in this simulation were determined experimentally. Moisture diffusivity of mango fruit was determined by minimising the sum of squares of the ...

This article presents the thin-layer drying of peeled litchi, which was conducted under controlled conditions of temperature and relative humidity. It was observed that the drying temperature has some influence on the drying rates of peeled litchi, so that the higher the temperature the less the dry...

This article presents experimental and simulated results of drying of peeled longan in a side-loading solar tunnel dryer. This new type of solar tunnel dryer consists of a flat-plate solar air heater and a drying unit with a provision for loading and unloading from windows at one side of the dryer. ...

A two-dimensional finite element model has been developed to simulate moisture diffusion in longan fruit during drying and moisture diffusivities of the components of longan fruit determined experimentally are used in this simulation. Shrinkage of the flesh of longan during drying is also taken into...

The equilibrium moisture contents of litchi (Litchi Chinensis Sonn.) were experimentally determined using the dynamic method at temperatures of 30, 40, and 50°C over a range of relative humidity values of 12 to 95%. Five models were tested to fit the experimental isotherm data of litchi. The GAB mod...

The components of the longan fruit were modeled as sphere for seed, cylinder for seed stalk, and slab for seed coat, shell, and flesh. The moisture diffusivities were determined by minimizing the sum of square of derivations between the predicted and experimental values of moisture content of thin l...

In this paper, thin layer drying of peeled longan is presented. Thin layer drying of peeled longan was conducted under controlled conditions of temperature and relative humidity. Drying air temperature has great influence on the drying rates of peeled longan and drying time decreases with the increa...

This article presents experimental performance of a batch-type longan dryer using a biomass burner with air flow reversal and also presents modeling of the longan dryer for drying of whole longan. The dryer essentially consists of a biomass burner and a drying bin with an arrangement for periodic ai...
