Prosopis africana is an under utilized tree crop with immense medicinal and industrial values. Manual threshing of the pods to extract the seeds is uneconomical, time consuming, associated with drudgery and low output capacity. A motorized Prosopis africana pod thresher was designed, fabricated and assessed for performance. The main components of the thresher include hopper, threshing unit, cle...

kermanshah province is the main producer of various chickpea cultivars in iran. in this study a laboratory peg-tooth thresher was employed for chickpea threshing. the effect of cylinder speed (9, 12, 15 m/s), concave clearance (12, 14, 16 mm), feed rate (80, 160, 240 kg/h) and material moisture content (5, 10, 15% w.b.) was studied on percentage of grain damage, threshing efficiency and percent...

A decorticating machine for Prosopis Africana was developed, tested and evaluated. Prosopis Africana is popular in the Sub-Saharan Africa, with all the parts of the tree useful for medicinal purposes. This study focuses on the threshing of the pod to obtain the seed, which is the most widely used of the parts of the Prosopis Africana tree. Results from preliminary investigations carried out of ...

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...

This paper concerns the analysis of the relationship between the threshing process in an axial flow harvesting machine and its vibro-acoustic behaviour. Several indoor and outdoor measurements are performed in various operational conditions in order to evaluate their influence on the vibration response of the threshing unit. The test results have been used to identify how the vibration and soun...

In this article we describe the CEP package for compressing EPS files. It belongs to the public domain and was released at the GUST meeting in Bachotek, 1997. The amount of disk space occupied by bitmap graphics is a well-recognized problem. For example, a 300 dpi picture (A4) contains ca 8700000 pixels; assuming that each CMYK pixel occupies four bytes, one obtains ca 35MB of disk space needed...
