“…Rotating treatment made the value of heating uniformity index scattered within 0.027 ± 0.002 and 0.041 ± 0.007. Movement and mixing operations of food materials could improve heating uniformity effectively (Bedane et al., 2017; Zheng et al., 2016; Zhou & Wang, 2019). The movement of pea grains in rotating container including horizontal and vertical spatial motion and therefore the uniformity of RF heating was significantly improved.…”

A radio frequency (RF) heating system was used to process green peas and a rotating system was introduced to improve heating rate and heating uniformity. Results revealed that rotation treatment accelerated heating rate effectively and improved heating uniformity index significantly (p < 0.05) from 0.175 (0 rpm, 55°C) to 0.029 (60 rpm, 55°C). After being treated with RF and traditional hot water blanching at 85°C, the residual lipoxygenase activities of green peas were 1.90 ± 0.71% and 35.51 ± 5.25%, respectively, confirming RF possessed better blanching efficiency. Meanwhile, weight loss, electrolyte leakage rate, color, and texture of green peas all had significant changes (p < 0.05) through RF heating. Practical Application A rotation device can effectively improve heating uniformity of RF electromagnetic heating. The rotation device could be expanded or further developed into continuous feeding conveying device for industrial production.

Food-borne or plant diseases mainly rely on the spread of seeds with pathogens. It is vital to eliminate food/seed-borne pathogens of seeds and their products before commercial import/export or circulation. Radio frequency (RF) heating is identified as an effective method with lack of chemical residues, rapid or volumetric heating and large penetration depth, and also validated as a potential physical method to eliminate pests or pathogens in agricultural products or foods. Although, many reviews have summarised the applications of RF treatment during the process of foods, little comprehensive review has been focused on seeds and their products pasteurised by the RF energy. Comprehensive summary about principles and main applications of RF energy for pasteurising seeds and their products was reported in this review. This review also introduced some typical RF heating systems, thermal death kinetics of pathogens, influences of RF heating on germination rate of seeds and some ways for improving uniformity of RF heating. Furthermore, this review recommended the future research directions about treatment of seeds and their products using RF energy, especially for seed industry to control the pathogens in seeds without reducing their quality after RF treatments.

The mechanism that carries the powder or tiny granular particles with the rotational movement of the spiral shaft is called the screw conveyor. The working principle of screw conveyors is transporting dust particles due to rotating the screw shaft placed in a cylindrical pipe with engine power. The transport process transfers the powder particles to the conveyor from the feed pipe at the top of the mechanism to the wings (helix) of the helix shaft. In this study, a scaled prototype of the screw conveyor was produced. Different Bayburt stone (Tüfit) sizes were transported utilizing the prototype, and natural frequency changes were measured during transportation. Consequently, it is observed that the different micron sizes of stone particles affect the natural frequency of the screw conveyor.
