HOME DRYING OF TOMATOES BY MICROWAVES.

Overall Quality of Fruits and Vegetables Products Affected by the Drying Processes with the Assistance of Vacuum-Microwaves

The seasonality of fruits and vegetables makes it impossible to consume and use them throughout the year, thus numerous processing efforts have been made to offer an alternative to their fresh consumption and application. To prolong their availability on the market, drying has received special attention as currently this method is considered one of the most common ways for obtaining food and ph...

Experimental System and Tests to Optimize a Tomato Drying Process

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 develo...

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

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Thermite powder ignition by localized microwaves

This paper presents a new method to ignite pure thermite powder by low-power microwaves ( 100 W). In this method, the microwave energy is supplied locally to the powder. It creates a confined hotspot, and initiates a self-propagating combustion in the entire powder volume. The coupled thermal–electromagnetic interaction evolved within the powder prior to its ignition is simulated theoretically,...
