| Apply to solve the problem and to overcome the shortage in the product existence. The author's skills that come from the long time practice and the author's specialty technology of the flue curing and the flue curing barn were combined, a measurement and control system for tobacco leaf curing was developed. In order to make them suitable to each other, the used to means in which only attach importance to the computer and think little of parts was avoid in the field. Parts of the system that performing monitor and the major function of computer were enough considered. 3 License obtained (number: 03217049.1 03217048.3 0321215564.6)The percentage of the first-class leaf increased by 4.37 percent cured by the automatic control system. The average price increased by 0.69yuan and the waste of coal was decreased by 0.34kg per kg. Manual work of curing was also decreased obviously. The purpose of improving the quality of the tobacco leaf decreased the labor of curing and saving coal was realized.In order to improve the applicability and the pertinence of the measurement and control system, the characteristics of 3 tobacco's variety was tested. The results showed that the rate can't assort with each other between the water losing and the yellowing is the key factor for Cuibi-1 of improving the cured leaf quality. Yunyan85 is an variety with easy yellowing, the yellowing and the characteristics of curing of K326 is between Cuibi-1 and Yunyan85.Comparison effects of different kinds of hot-air circulation fan's power on the characteristics of barn and the cured leaf quality were made. The testing barn was 270cm×330cm with the space separated into five floors and a clearance of 25cm between two rods with leaf plait. The results showed that hot-air circulation with the fan of 90-120W has significantly effects on increasing characteristics of hot-air circulation in the barn and improving the cured leaf quality. Provide the technique of the fan's power match the barn. |
