Development of Beans Dehulling Machine

Olutayo L.A, Mogaji K.O, Fawohunre A.J and Akinfiresoye W.A

Beans are dehulled from its coat locally, which has been in existence for long i.e. use of mortar and pestle to pound soaked beans. Improvement on this technology has been the focuses of study in dehulled beans seed. It is worthwhile, to note that the production and consumption of bean seeds have a great influence on the nutrition. In Nigeria the mechanized method of dehulling is required to boost dehulled beans production. Therefore, a beans dehulling machine that is easy to operate, maintain and at low -cost was designed and fabricated. The major components of the machine are; frame, hopper, dehulling chamber (abrasive material) and the discharged unit. The working principle of the machine is by feeding a soaked beans into the machine through the hopper, as the shaft rotate, it also carries it until the beans travel radially along the roller; the abrasive surface of the insulator dehulls it from its coat. The dehulled beans and its coat come out through the machine outlet in the lower half of the dehulling chamber. The bean dehulled is a function of the clearance between the hopper and the Dehulling chamber. The machine had a throughput of 45 kg/hr. and functional efficiency of 70 %. The total production cost of the machine was N65, 200 as at time of fabrication.it is recommended for small and medium producers of processed beans

Analysis of the theoretical capacity of a bucket wheel excavator in function of the geometric parameters of slice

Haliti R.

Surface excavations are essential for surface mining operations to proceed in the extraction of mineral deposits .The bucket wheel excavator(BWE) ,which is utilized for digging rock, is one of the predominant mining equipment in a surface mine ,as a continuous mining system :Bucket Wheel Excavator –Belt Conveyor – Stakers (EKS) . BWE is a heavy-duty continuous excavator, which is capable of producing a large output The purpose of this paper is to provide comparative analysis of the geometric parameters of slice to determining the optimal parameters of dimensions slice and its influence on capacity of bucket wheel excavators .It will show the technological schemes of work of the excavators bucket wheel which will be obtained the optimal parameters for the operation of the excavator bucket wheel in different working conditions viewed from geometric characteristic of cutting material

Titled Bianchi Type I Cosmological Model for Barotropic Perfect Fluid

Sheetal Mandowara , Gajendra Pal Singh and Atul Tyagi

We have investigated Tilted Bianchi type-I cosmological models with Barotropic perfect fluid ρ=γε , where γ is a constant. To get deterministic model, we assumed that ,A= BC  a condition between metric potential. The Physical and Geometrical aspects of model are also discussed

Backward Difference and Ratio Operations: Representation of Numerical Data on a Pair of Variables by a Polynomial Curve

Dhritikesh Chakrabarty

One method has been constructed for representing a given set of numerical data on a pair of variables by a polynomial curve due to the necessity of such method/formula in interpolation by the approach which consists of the representation of numerical data by a suitable polynomial first and then to compute the value of the dependent variable from the polynomial corresponding to any given value of the independent variable. The method is based on two numerical operations namely backward difference operation and ratio operation. This paper describes the theoretical derivation of the method with numerical example in order to show the application of the method developed to numerical data.
