Non-fibrous, liquid cell materials having uniform properties in all direction at the time of cutting, ii. Other considerations in designing the machine include, cutting resistance of the crops, moisture content, thickness of slices, speed of cut, maximum power requirement, power source and contamination. The frame was made to a rectangular box form using angle iron and mild steel plate. The cutting disc Fig. There are also several manually operated kitchen—size chipping and slicing machines in the market. The process of cutting or slicing the crops gives rise to faster cooking. With technological advancement, there is progressive increase in awareness of the importance of using mechanical devices to slice agricultural produce.
Kordylas reported that plantain is best preserved in the dried form by processing into flour and chips for human and livestock consumption. In medicine, onion reduces the clotting of platelet in the body and it is reputed to lower raised blood sugar levels. It also has a covering unit Fig. Kerta Laksana of Indonesia had made a pedal — driven cassava slicer fitted with one large slicing blade. It also reveals that, there are no significant difference between medium size and large size for carrot, but medium size will give high performance for the machine in terms of efficiency. Published online Feb The medium size has decrease in capacity with increase in speed.

Slicing operation is achieved by cutting, which involves moving, pushing or forcing thin sharp blade or knife through the materials resulting in minimum rupture and deformation of the materials Raji and Igbeka, Food and Agriculture Organization of the United Nations.
This results in minimal deformation and plajtain of the fruits cell wall.
Pitch length of the belt: The required rotational force F cto drive the shaft was obtained using the relation below Ob et al. A tachometer was employed to ensure correctness of operating speeds as determined in the design calculation. The orthographic projection and the exploded view of the machine are presented in Figs.

Pergamon Press Ltd, London, pp — The diameter of cutting disc on which blades were to be mounted was 22 cm i. Transactions of the ASAE, 16 6: Kachru et al observed that during cutting, a cutting edge knife penetrated into a material, overcoming its strength and thereby separating it. The required shaft diameter is determined revuew the formula Hall et al.
National Center for Biotechnology InformationU. In medicine, onion reduces the clotting of platelet in the body and it is reputed to lower raised blood sugar levels.
Also, some of these machines are designed for a particular type of crop and cannot plantan used for other crops. The plantain slicer is considered a light duty machine with service factor of 1.
Different parts of the plantain slicing device: The olantain of almost all processed root and tuber crop products depends on reducing the moisture to a level which prevents the growth of microorganism. Kachru, developed a plantain-slicing machine and evaluated its performance with respect to parameters such as cutting velocity, orientation of hopper, shear angle, level angle, number of blades of the machine.
The mass of each category was determined by an electronic balance. According to Kachru et al. That is to say the difference will influence the litearture of the machine.
Development of a plantain slicing device
The slicing unit, a very important unit of the machine, performs the actual slicing. Due to its low-cost, it will be suitable for use in Nigeria and other plantain producing countries in sub-Saharan Africa, where patented mechanized plantain slicing machine is not readily available, or where available, the costs are prohibitive.
Journal of Agricultural Engineering Technology, 2: The capacity increased with increase in speed. The processing of yam into flour increases its storage life Osagie, since the moisture content is drastically reduced, making it less favourable to microbial activities.
It also reveals that, there are no significant difference between medium size and large size for carrot, but medium size will give high performance for the machine in terms of efficiency. Individual plantain fruit has a protective outer layer with a freshly edible inner part which is cooked by boiling, steaming, baking, roasting or frying and may be processed into plantain chips Asoegwu et al.
Laboratory Analysis of the Combine Header. However, large size potato decreased in efficiency with an increase in speed. The frame was made to a rectangular box form using angle iron and mild steel plate. The machine is therefore observed to perform best at the optimum operating speed of 41 rpm for all the crops selected except carrot.
There was no significant difference between small size and medium size onion. The shaft is made of mild steel and is being supported on two rolling elements bearings and at both ends of the shaft will be attached the driven pulley and the cutting disc.
Both small and large sizes of potato gave the same trend. It was discovered that the machine cannot be operated beyond 50 rpm because it pushed samples instead of slicing, which implies that rotational speed less than 50 rpm is adequate for the operation of machine.
