Design and construction of an electric maize rotisserie.

Abstract

Food processing is a very important aspect in daily consumption. food processing is the way raw ingredients are transformed into consumable food. Roasting makes maize edible for consumption, in the, home of small entrepreneurs by the vendors. Roasting is Gone using, barbecue where the device cooks food by applying heat-directly from below. Selling roasted maize is the most common source of' income to most small scale maize growers. And the roasting process requires continuous fanning of charcoal to. maintain the charcoal burning, which is 11 stressful practice. Many technologies have been developed to make roasting process easy but these technologies are not in Uganda, in order to reduce the stress when roasting maize, know the level of cook, and to also increase efficiency; the development of an electric maize roasting machine was observed necessary. The design parameters of maize rotisserie was done depending on the available researched technologies available on market in 'different developed countries. Experimental research design was adopted in the investigation to determine the efficiency of the, maize rotisserie' for roasting maize cobs. The machine performance efficiency was calculated and it was 71.4%~ An~ the venders-were observed to take less time to roast. many number of cobs in batch than when using tradition methods. Also hygiene, of roasted cobs was improved since it is a clean operating process when using ail electric maize' rotisserie.
