DESIGN OF MELON DE-HUSKING AND SEPARATION MACHINE

INTRODUCTION
Nigeria is an agricultural nation. Melon (Citrullus Vulgaris) is widely cultivated in Nigeria, among other seedlings during the planting season yearly. Several tones of the melon seeds are gathered each harvesting period but only very low percentage of the total harvest are dried by atmospheric draught and bagged for storage. High percentage waste is encored due to lack of good processing and storage facilities.Melon when properly processed yields a lot of by-products, which could be used as food or as raw material for small and large scale industrial manufacture melon is highly enriched with oil. It has about 45% oil content. The oil could be extracted to form a very good source of vegetable oil. After pressing out the oil, the remaining product can be used as food for human of as an additive in agro-feed manufacture. Melon without oil can be grounded and used as thickener or binder in the chemical and pharmaceutical industries.The outside shell of the melon seeds when properly harvested in large quantity can equally be used in preparation of agric feed. The shell has about (12-55) MJ/kg calorific value and therefore can be used as a source of energy for industrial use.The major problems encountered in the processing of melon seeds are the removal of the yellow outside shell and the separation of the broken shells form the white seeds. Locally as at now, manual approach is used for the de-husking and separation.
