A case of closed injury to the cervical portion of the trachea, caused by a wheat-threshing machine, is reported. The patient presented with extensive subcutaneous emphysema, but without any respiratory distress. The unique problem faced during the management of an anterolateral tear of the trachea is highlighted.

since threshing is one of the most sensitive rice post-harvest processing operations, this study was conducted to evaluate the threshing performance in axial - flow paddy thresher. independent variables consisted of: drum speed at five levels (550, 650, 750 and 850 rpm), equivalent to peripheral velocities of: 14.67, 17.35, 20.01 and 22.37 m/s, respectively, paddy moisture content at two levels...

Corn is a crucial crop and has vital application value in many aspects of our lives. Mechanical grain harvesting the developing direction corn technology, with threshing as its most imperative procedure. The quality device harvester major influence on damage rate, loss other parameters. Therefore, it great significance to effectively lower rate process threshing. This review presents research p...

A cowpea thresher that uses petrol engine was developed to overcome drudgery of threshing with manually operated and also replace motorized cannot be used in areas where there is no supply electricity. The performance tests on the machine were replicated three times using 10000, 8000 6000 grams kannanado pods at cylinder speed 700, 800 900 rpm each moisture contents 11.05%, 13.65% 14.75% respec...

Rice is a widely cultivated food crop worldwide, and threshing one of the most important operations combine harvesters in grain production. It complex, nonlinear, multi-parameter physical process. The flexible device has unique advantages reducing damage rate already been major concerns engineering design. Using measured test database bench, rotation speed cylinder (RS), clearance concave sieve...
