Experimental System and Tests to Optimize a Tomato Drying Process
نویسندگان
چکیده
The aim of the current work is to give a contribution to the study of the drying process of tomatoes through the synergy of the hot air and microwave technologies. The drying of tomatoes is a process commonly used to preserve the product and to prolong its shelf-life. In this paper, four experimental tests on the product under study, were carried out. Then, different drying diagrams were developed and analyzed taking into account the conventional air system, the microwave system and the simultaneous use of hot air and microwaves. The drying tests were carried out using the "Cencara" tomatoes type.

Sun drying is a well-known food preservation technique that reduces the moisture contents of agricultural products. Shrinkage, rehydration ability and color of food materials during air drying adversely affect the quality of the dried products. Since all fresh tomatoes can not be consumed at the time of harvest, preservation provides a larger market, allowing consumers to buy the preserved toma...

متن کاملExperimental Survey on Microwave Drying of Porous Media
The cost of drying carpet which is done toward the end of the manufacturing process, is quite high. The carpet industry has been using convection drying for many years. Little attention has been given to quantifying the effect of microwave power during the drying of carpet. An experimental system was developed whereby air was introduced into the cavity of a domestic microwave oven. The resu...
