1.0 Introduction
In unit operation, mixing of two or more substances have posed difficulty in chemical engineering process. Because of the problem encountered during the process. Industrial equipment are being designed from experience rather than the fundamental theory because of the high dependency on the effective mixing of fluids and solids in unit operation process.
The term mixing, is applied in preparation of uniform combination of two or more material, which may differ in degree of homogeneity of mixed material. The product from the process may be homogenous or heterogeneous.
In most chemical industries, factories even homes, two or more substances are expected to be properly mixed for a specific purpose. To enhance these process, experimental agitation were developed to serve a broad practical and basic fluid mixing problems. In process operation, he action of agitation enable one to predict the performance of a full equipment or help in establishing more general correlation in fundamental studies.
The application of propeller agitator is common in low viscous liquid which is commonly used in confectionary industries, liquid food drinks e.g five-alive, bottled drinks and canned beer.
Mixing machine (propeller egitator) is therefore indispensable to humanity and nutrition based industries. However, varied method of material mixing are applicable in some cultural setting to form a homogenous product.
There are varieties of mixers, but in selecting a mixer for a purpose, some basic factors are put into consideration such as process requirements, equipment cost, flow properties of the process fluid. The constructional material to achieve high level and the equipment chosen to meet all purpose requirements. A good mixer is however the one which provides a well mixed product at lowest cost.
1.1 Scope and Objective of the Project
The scope/objective of constructing a propeller agitator that is versatile in application in small scale, laboratory and domestic purpose which is usually of low viscous fluid.
From literature survey on mixing constructed propeller agitator is not used for continuous process. The components which are shaft blade and the impeller are for effective mixing.
