ANALYSIS OF ALTERNATIVE METHOD TO GRINDING MACHINE
2.1 MANUAL GRINDING MACHINE
The manual grinding machine is a model of all grinding machine and it is small and occupies a little space. It has a stand that saves its shock absorber. Wonder is connected to the shaft through to the power input is transmitted when the food is dropped into the wonder the wonder will be conveniently okay. The shaft crushes it before transferring into grounding unit where it will be grinded before collection through collection of its unit. This manual grinding machine has more advantages than other method and it is more efficient as it was operated by electric.
2.2. GRINDING STONE
Grinding stone is an indigenous grinding stone with a top stone or miller and it is made from sand stone, which has a rough surface for grinding. Stone were used by indigenous women in the semi arid region for cooking purposes and it also used to grind seeds and nuts. The process of grinding stone is tedious and contains more time. This cannot be used for grinding large quantities of food and hard foot items e.g cassava, yam, flour, maize etc.
2.3 CHOICE OF ALTERNATIVES
The choice of the method to be used depends on the type of food stuffs to be grinded and its quantity that was available for grinding.
Manual grinder machine will be preamble when grinding domestic food items like pepper, beans, etc while on the other hand, grinder mill will be better when grinding item like flour, cassava e.t.c. because a solid grinding machine occur under exposure of mechanical forces that trench the structure by overcoming of the interior bonding forces. Mill is a device that breaks solid materials into smaller pieces by means of grinding, crushing or cutting e.g yam flour, cassava, etc
2.4 MORTAL AND PESTLE GRINDING
The mortal and pestle is a device used since ancient times to prepare ingredients and substances by crushing and grinding them into a fine paste or powder. The mortar is a bowl, typically made of hard wood, ceramic or stone. The pestle is a heavy club-shaped object, the end of which is used for crushing and grinding. The substance to be ground is placed in the mortar and grinded, crushed or mixed using the pestle.
Mortal and pestle have been used in cooking up to the present day and it is used in cooking to prepare ingredients I such as tomatoes, bean etc.

CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONE1.0 INTRODUCTIONThe project titled fabrication of machine is used for grinding domestic food stuff like corn, pepper, beans, tomatoes, melone.t.c. The grinding operation was carried out in the olden days with the aid of grinding stone. This method is very tedious and unhygienic in nature. The particle of the grinding stone can easily be mixed with the grinding food items which may be hazardous to the food itself and also to the personnel undertaken such task by entering his or her bod ...
