Power transmitted, P, between the two shafts is related to the belt tension and its linear velocity according to the following Hall et al. The idler shaft was introduced into the machine to reduce the speed coming directly from the prime mover to desired level. Click here to sign up. Inaugural Lecture Series No. Exploded view of the slicing machine showing the component parts. These conveying discs are 9 in number and they were arranged in such a way that they are separated by spacers between then to achieve the desired thickness of slices Figure 2. Nevertheless, as the plantain chips industry attract more investments depicted by the increase in the rate of packaged brands that are being sold on Nigerian roads, markets, stores, fast food joints and supermarkets, the need for a simple, affordable, easy to maintain slicing device cannot be overestimated.
For onion, the small group decrease in throughput capacity with increase in speed. Experimental Procedure Preliminary tests were conducted to determine the optimum speed of machine. Throughput capacity was defined as the ratio of the quantity of sliced materials collected from the machine outlet to the time taken. Appropriate Agricultural Mechanisation Technologies: Journal of Agricultural Engineering and Technology, 4:
Therefore, the design kiterature requirement of the plantain slicer is calculated to be These conveying discs are 9 in number and they were arranged in such a way that they are separated by spacers between then to achieve the desired thickness of slices Figure 2. The slicing unit, a very important unit of the machine, performs the actual slicing.
It was bolted to the top of the main upper housing. Integrated Food Science and Technology, for the Tropics. An electric motor stand with four slots holes for pre-tensioning of belt by adjustment of center distance between the driving and driven pulleys is also provided. Further modification of the machine is necessary to improve the performance of the machine. Various sizes of such machines are available from as small as 1. Presently, there is need for increased preservation of root and tuber crops in the country in order to prolong storage plwntain.
Efficiency of the slicer Efficiency of the plantain slicer was determined based on the average number of slices produced. This may be as a result of soft texture of the crop. Open in a ;lantain window.
Mechanisation of Nigeria Cassava Production and Processing: It consists of the driving sliecr small pulleydriven pulley big pulley and a belt to transmit the drive from the driving pulley to the driven pulley. Reveiw length of the belt: From this calculation, a motor of 1. They include grinding or grating cassava, yamdicing potato, yam, onionslicing carrot, onion, yam, onion and bananamilling rice, corn and wheatchipping cassava, yam and banana. Crops are commonly sliced and prepared by frying in hot oil or roasting.
The objective of this work was to develop a simple motorised plantain slicer for small scale plantain chips producers. Electric motor was used to drive the driven pulley Fig.
luterature This post-harvest loss reduces the income derivable from the crop production by the farmers. Isometric view of the multi-crop slicing machine. They are best preserved in the dried form by processing into flour, chips and pellets for both human and livestock consumption.
Macmillan Publishing Company, New York. The performance of the machine was evaluated in slicing four selected crops carrot, potato, onion and yamgrouped into three sizes small, medium and large at five machine speeds of 39 rpm, 41 rpm, 43 rpm, 46 rpm and 48 rpm respectively.
Capacity is 21 — 23 kg per hour. Also, some of these machines are designed for a particular type of crop and cannot be used for other crops. Liteeature is made up of the following.
While medium and large group increased in throughput capacity with increase in speed. In West Africa, fufu, similar to that made from cassava, is readily prepared from yam tubers. Skip to main content. This may be as a result of texture and fibre content of the crop.
By-products such as potato starch, glucose kiterature dextrose are used in biscuit production and in the brewing industries in the producing, confectionary, for the distillation of alcohol and to make various types or tapioca. Literatture sweet potato is held on the cutting platform against a plate, which controls the thickness of slice.
There are cassava chippers, tomato slicers, okro slicers and other root and vegetable choppers.
