Abstract

Design of axialflow thresherfor pepperThe pepper threshing practice has been carried out using traditional method in which the pepper berries are usually trampled. This method is neither efficient nor higienic, and it also causes high losses of the berries. To overcome those problems, an experiment was carried out to make an axial flow thresher. The experiment was conducted at Research Institute for Spice and Medicinal Crops from April to December 1999. The experiment consisted of three steps, namely designing, constructing and testing. The objective of testing was to determine the optimum operation condition of the thresher. The testing was designed as a completely randomized complete design with three replications. The raw material for testing was pepper berries (Lampung Daun Lebar variety) of 8 - 9 month old. The result showed that the optimum condition for threshing process was 300 rpm cylinder rotation, with the spike separation process using 7.5° sieve angle. The performance of pepper thresher on that condition was : threshing eficiency 98.55%, spikes separation eficiency 89.22%, berries on spikes outlet 5.20% and berries damage 6.30%. The capacity of thresher was 260.56 kg raw material/hour. The operational cost was Rp 27.28/kg raw material, lower than that of the traditional threshing method (Rp 50/kg raw material).

Abstract

Design of the hand-powered thresher for black pepper processingProcessing of pepper berries (Piper nigrum L.) into black pepper needs thresing to remove the beries from the stalks prior to sundrying. Until now, the threshing practice is caried out by traditional method in which the pepper beries are trampled. This method is not eficient nor hygienic and it also causes high losses of the berries. To overcome those problems, a hand-powered thesher has been designed. The experiment consisted of thee steps, namely designing, constructing and testing. The threshing mechanism was based on impact and friction, whereas the separation of the berries from the stalks was based on the difference in shape and dimension. The dimension of the pepper thesher is 900 mm length, 450 mm width, and I 200 mm height. The test results showed that the hand-powered thresher have a good performance. The capacity of the thesher is 100 kg of pepper berries (berries + stalks) per hour. The operational cost is Rp 30.02 per kg of pepper beries, cheaper than that of the traditional theshing method (Rp 50/kg). This equipment is easy to apply in rural area, and can covee the theshing operation of 2.1 hectare of pepper plantation during harvesting periode.
