Design And Fabrication Of Rechargeable Blender

INTRODUCTION
1.1 BACKGROUND OF THE STUDY
A rechargeable blender is described as a battery or direct current (dc) powered kitchen and laboratory appliance used to mix, or emulsify food and other substances. A stationary blender consists of a blender jar with a rotating metal blade at the bottom, powered by an dc motor in the base. It is USB rechargeable portable blender which is great for traveling, camping and outside activities.
A conventional blender for mixing and shredding fruit or vegetable generally includes a motor base for receiving a motor therein which drives a blade means in a bottom of a container. Fruit and/or vegetable in the container are shredded or cut by the rotational blades on the blade means to become liquid. However, because the motor generates heat during operation and there is no ventilation device in the motor base so that the term of use of the motor will be reduced by the heat. The dc motor is generally threaded to the motor base and this takes a lot of time.
Different blenders have different functions and features but product testing indicates that many blenders, even less expensive ones, are useful for meeting many consumer needs.

1.2 PROBLEM STATEMENT
A conventional electric blender only operate whenever there is power supply, imagine in a developing country like Nigeria where the level of power supply is low – using an electric blender becomes a problem. This device came to overcome this problem of erratic power supply; it uses a rechargeable battery to sustain the blender whenever there is power failure.

1.3 OBJECTIVE OF THE PROJECT
This work intends to fabricate a rechargeable blender that removes heat from the bottom of the motor base and the fruit and/or vegetable will jump to be cut during the rotation of the blade disk.
At the end of this work, student involved would be able to fabricate a rechargeable blender comprising:
i. a dc motor base having a base and a plurality of ventilation holes defined through a bottom of the base;
ii. a dc motor connected to the base;
iii. a casing mounted to said base and a central hole defined in a top of the casing
iv. a container mounted to the motor base and a blade device located on an inner bottom of the container
v. a rechargeable battery; and
vi. a dc motor retainer extending from a top sauce of the base.

1.4 SIGNIFICANCE OF THE STUDY
Working on this topic makes possible for the student involved to become familiar with operation and application of a dc motor and a rechargeable battery. It makes it easier to introduce more fresh fruits and vegetables in your lifestyle, vary the tastes and textures, with ease, and enjoy super-foods that are barely cooked, packed with vitamins, oxidants and healthy nutrients.
Besides helping you cook larger quantities of fresh veggies and fruits, a rechargeable blender can successfully do a lot more: making smoothies, preparing purees from different nuts, grinding flour, making cold, creamy soups, preparing the creams, barter or dough for different cakes/pizzas, making your own yogurts or vegetable milk, preparing pesto or crushing ice.
Other significance of this work is that:
• has large visible measurement marks
• ease of use
• low noise during usage
• power usage (typically 1253.18w)
• ease of cleaning
• option for quick “pulse” blending

1.5 ADVANTAGES OF THE PROJECT
Construction: The construction of a blender is very sleek, clean and trendy. The best part of this blender is that they have a contemporary look and gives the cooking area a well defined look.
Easy to Charge: Can be charged by any USB device
Double safety protection switches, and charge/discharge protection
Multi-function cups: Suitable for making protein shake, smoothie, juice, mixing vegetables and other baby food
Easy to clean: The juicer cup’s body and bottom can be separated, it is very convenient to clean. The cup body and the base are very well combined, not to worry about leaks
Assembling: It is very easy to assemble a blender and it is movable too.
Repairs: Blender is easily repairable, so, if any part is damaged, it can easily be replaced and re-installed.
Easy Cleaning: Cleaning a rechargeable blender is very easy because of its designing and a mere cloth wipe will keep your blender dust-free.
Durability: This type of blender set-up is durable in nature and if once installed.

1.6 PROBLEMS OF THE PROJECT
Costly: blender comes with a cost. Usually, this blender carries high-end articles and due to which they are very costly.
Bored: You will get bore from the style of blender sooner or later and will think of replacing it and will have to bear a cost again.
Expensive Spares: The spares of blender are very costly, so, if any of the part of modular kitchen is to be replaced, it will cost you a lot.
Regular Cleaning: blender requires daily cleaning else it looks dull.

1.7 APPLICATIONS OF THE PROJECT
Countertop blenders are designed to mix, purée, and chop food. Their strength is such that the ability to crush ice is an expected feature. Blenders are used both in home and commercial kitchens for various purposes, including to:
• Blend ice cream, milk, and sweet sauces to make milkshakes
• Mix and crush ice in cocktails
• Crush ice and other ingredients in non-alcoholic drinks such as frappuccinos and smoothies
• Emulsify mixtures
• Make smooth purées of semi-solid ingredients, such as cooked vegetables and meat
• Reduce small solids such as spices and seeds to powder or nut butters.
• Blend mixtures of powders, granules, and/or liquids thoroughly.
• Help dissolve solids into liquids.

1.8 LIMITATION OF STUDY
As we all know that no human effort to achieve a set of goals goes without difficulties, certain constraints were encountered in the course of carrying out this project and they are as follows:-
i. Difficulty in information collection: I found it too difficult in laying hands of useful information regarding this work and this course me to visit different libraries and internet for solution.
ii. Financial Constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet).
iii. Time Constraint: The researcher will simultaneously engage in this study with other academic work. This consequently will cut down on the time devoted for the research work.

1.9 PROJECT ORGANISATION
The work is organized as follows: chapter one discuses the introductory part of the work, chapter two presents the literature review of the study, chapter three describes the methods applied, chapter four discusses the results of the work, chapter five summarizes the research outcomes and the recommendations
