Thin‐layer air drying of soybeans and white beans

Abstract

A thin-layer air drying apparatus was designed and constructed to determine the drying characteristics of various agricultural and food products. The equipment was designed to monitor the weight loss during drying and to operate over a practical range of air temperatures and humidities. This paper presents a description of the apparatus and an evaluation of its performance.The results of studies conducted to determine the thin-layer drying behaviour of soybeans and white beans are included.

Drying behaviour of green beans

“…The experimental results were showed that air temperature is considered as the most important factor affected drying rate. Different authors reported similar results on drying of vegetables (Hatamipour & Mowla, 2003;Hutchinson & Otten, 1983).…”

“…This model was also used to fit the experimental data of soybean, white bean, green bean and corn (Doymaz & Pala, 2003;Hutchinson & Otten, 1983;Yaldiz & Ertekin, 2001). The model is given as…”

“…There have been many studies on the drying behaviour of various vegetables such as soybeans and white beans (Hutchinson & Otten, 1983;Kitic & Viollaz, 1984), green beans (Senadeera, Bhandari, Young, & Wijesinghe, 2003), red pepper (Akpinar, Bicer, & Yildiz, 2003;Doymaz & Pala, 2002), carrot (Doymaz, 2004), eggplant (Ertekin & Yaldiz, 2004), and pumpkin, green pepper, stuffed pepper, green bean and onion (Yaldiz & Ertekin, 2001).…”

Drying kinetics of black grapes treated with different solutions

“…Two-term exponential model is the first two terms of general series solution to the analytical solution of FickÕs second law, and has also been used to describe drying agricultural products (Hutchinson & Otten, 1983).…”

Effects of Dipping Solutions on Air-Drying Rates of the Seedless Grapes

“…Drying techniques were drawn attention of many researchers and many studies were done on the world (Hutchinson and Otten, 1983;Kitic and Viollaz, 1984). The most important point to pay attention is to remove wax film on grape that resists mass transfer during drying.…”
