Design and fabrication of a motorized/power operated plantain slicer for optimum chips production

Abstract

In Nigeria, plantain chips are in high demand and this demand is not being met by most small scale food industries and shops due to some critical factors. Shops are only able to fulfill approximately two-thirds of the demand. The biggest obstacle towards attaining self-sufficiency in the production of plantain chips is the intensity of labor involved and the tediousness of the process which often culminate into prolonged production time. Plantain has a large amount of sap and this causes the skin to adhere to the fruit inside. After peeling, they must be sliced into discs to fry into chips. Worker will hold up to eight plantains in one hand and rapidly slice them using a wooden mandolin. Because of the rapid pace at which they slice plantain and the absence of hand gloves on the workers, accidents are very often unavoidable. These presents health hazards to both the worker, who may develop infections from their injuries, and customers who may consume an unsanitary product. This development is very uncomfortable and tasking on the workers. They must hold the mandolin over the fryer so the plantains will fall in, which causes splashing of the boiling hot oil that occasionally hits and injures the worker. This research focused on design and fabrication of motorized / power operated plantain slicer to meet the raising demands for plantain chips in Nigeria. The objectives of this research was met as the machine has the capacity to produce plantain chips of uniform size in shorter time and a greater slicing efficiency of up to 96.84% while keeping the cost of the machine at an affordable price.
