最近,云南省电子工业研究所和昆明烟叶复烤厂联合研制成WYF-1型微波烟叶复烤机,已通过鉴定.WYF-1型机采用单电源双腔双口耦合隧道式加热器.在轻负载下,在915±25兆赫频段范围内,系统的实测驻波比在1.5左右;实际输出微波功率为23千瓦,运行稳定可靠;主要操作部位漏能小于20微瓦/厘米~2.按照工艺规程操作,用WYF-1型机复烤烟叶,其含水率、破碎率和砂土率均已达到国标(GB2635
Recently, Yunnan Institute of Electronics Industry and Kunming Tobacco Baking Factory jointly developed a WYF-1 microwave tobacco leaf roasting machine, has been identified. WYF-1 machine with single-supply dual-chamber dual-port coupled tunnel heaters. Under light load, the measured standing-wave ratio of the system is about 1.5 in the frequency band of 915 ± 25 MHz; the actual output microwave power is 23 kW, and the operation is stable and reliable; the leakage energy of the main operation site is less than 20 microWatts / cm 2; Craft operation, with WYF-1-type machine re-flue-cured tobacco, the moisture content, crushing rate and sand rate have reached the national standard (GB2635
