Kenaf Seed Thresher
KENAF SEED THRESHER
Background
Kenaf is grown from seed and a large quantity of seed supply is needed for commercial production. Kenaf seed production is labour intensive especially in the harvesting and seed processing aspects. Besides, threshing kenaf seed causes severe skin irritationto the field workers. Mechanization of seed production is needed to overcome some of these constraints. A seed threshing machine is recommended to facilitate smallholders to solve labour problems, reduce seed production cost and skin irritation problem.
Description of Innovation
A seed thresher machine, modified from a soya bean thresher, has a small 4-stroke gasoline engine, 2.7 HP Robin EY15 as main power source. It is designed to thresh kenaf seed. The machine has three unique mechanical processes:
A seed thresher machine, modified from a soya bean thresher, has a small 4-stroke gasoline engine, 2.7 HP Robin EY15 as main power source. It is designed to thresh kenaf seed. The machine has three unique mechanical processes:
# The first process comprises two closed range spike-tooth cylinders with adjustable threshing space for pulling function of kenafstems and at the same time threshing the capsules at a rotation speed of 230 rpm. The adjustable space is supported by 2 pairs of springs to accommodate various sizes of kenaf stems.
# The second process is to separate the seed from capsules usin a beater which hit the press capsules in the closed part at a spindling speed of 460 rpm. The seed is beaten out of capsules while the stumps are then pushed out from the thresher.
# The final process is cleaning. The seed, which have been beaten out, will fall down into the sieve which is located under the beater. The sieve screen filters the seed from the chaffs such as cores, capsules, leaves and other unwanted materials. The sieve is elongated to collect the seed, while the trash and debris are forced out together with the stumps. The machine is mostly recommended for seed crops harvested during dry season.
