Research Progress in the Application of Radio Frequency Technology in Fruit and Vegetable Drying

Shipin gongye ke-ji, 2022
Drying is one of the most important technologies for fruit and vegetable processing. The energy consumption during drying and the quality of dried products are highly correlated to the selected drying methods. As a new type of physical heating technology,

Statistical signature of active D-region HF heating in IRIS riometer data from 1994-2004 [PDF]

, 2007
International audienceIn this paper we study the effect of artificial HF heating on cosmic radio noise absorption in the D-region ionosphere. The effect has earlier been studied theoretically in idealised cases and without experimental verification. Here

Direct measurement of axial momentum imparted by an electrothermal radiofrequency plasma micro-thruster

Frontiers in Physics, 2016
Gas flow heating using radio frequency plasmas offers the possibility of depositing power in the centre of the flow rather than on the outside, as is the case with electro-thermal systems where thermal wall losses lower efficiency.

Effect of freezing rate and comminution on dielectric properties of pork

Czech Journal of Food Sciences, 2013
The impact of comminution and the freezing rate on the dielectric properties (ε' and ε'') of meats measured at frequencies used for cooking, i.e. radio frequency, RF (27.12 MHz), and microwave, MW (915 and 2450 MHz), were evaluated. The temperature rises
