Construction Of A Blender
The construction of a blender involves intricate engineering to integrate various components seamlessly, facilitating efficient blending processes. Key elements include a robust motor, adept at generating sufficient power to pulverize ingredients; durable blades crafted from stainless steel or other resilient materials, designed to finely chop and blend; a sturdy base providing stability during operation; a transparent pitcher, often made of glass or BPA-free plastic, allowing users to monitor blending progress; and intuitive control mechanisms such as speed settings and pulse functions, enabling customization according to desired textures. Additionally, safety features like secure locking mechanisms and overheating protection ensure user protection. The assembly of these components harmonizes mechanical prowess with user-friendly design, culminating in a versatile kitchen appliance adept at concocting smoothies, soups, sauces, and more.
Blender is an electric machine for size reducing soft food or liquid mixture. Blender is some time called liquidizer consists of a glass jar or jug containing a steel blade assembly at the base driven by a small electric motor.
Construction of blender was done based on the principle of size of reduction using electric motor as the major driver force. During the construction of blender, we adopted different stages which includes:
i. The production of preliminary drawings with details and dimensioned sketches.
ii. Choosing of design and materials used in the construction.
iii. Construction and fabrication of all the component of the blender which includes blender container, shires, blade and the motor, all these was coupled together.
iv. Examination and testing of the performance and efficiency of the machine.
After strictly adopting the aforementioned stages, a well structured blender made of steel (stainless & mild) was obtained as the end product. Also, for effectiveness of the size reducing action, the steel blade was sharpened and also the number of the blade was increased. Actually, the material selected for this project has reduced the cost of painting and it is found to be anti corrosion due to the high degree of chromium contents and other alloy.
The main object of this project which is to be able to fabricate the component using the primary tool in the mechanical workshop was achieved after all the difficulties uncounted during the construction of blender.
The project construction of blender in relation to materials for construction costed N22,000. Comparing this with the price of normal domestic blender, can be seen to be extremely high. This high is due to the material of construction and fabrication processes.
In considering all the resources channeled towards the construction, it can be rightly stated that the machine is economical in relation to materials used in the construction and the performance of the machine after construction.

INTRODUCTION
Blender as a size reduction machine is mostly used in both home for domestic purposes and in the chemical industry. In chemical industry, size reduction or communication is usually carried out in order to increase the surface because, in most reactions involving solid particles, the rate is directly proportional to the area of contact with a second phase. Thus the rate of combustion of solid particles is proportional to the area presented to the gas, though a number of secondary factors may also be involved; for example, the free flow of gas may be impeded because of the higher resistance to flow of a bed of small particles. Again in leaching, not only is the rate of extraction increased by virture of the increased area of contact between the solvent and the solid, but the distance the solvent has to penetrate into the particles in order to gain access to the more remote pockets of solute is also reduced. This factor is also important in the drying of porous solids, where reduction is size causes both an increase in area and a reduction ion the distance the moisture must travel within the particles in order to reach the surface; in this case the capillary forces acting on the moisture are also affected.
There are a number of other reasons for carrying out size reduction. Thus, it may be necessary to break a material into very small particles in order to separate two constituents, especially where one is dispersed in small isolated pockets. Further, the properties of a material may be considerably influenced by the particle size; for example, the chemical reactivity of fine particles is greater than that of coarse particles, and the colour and covering power of a pigment is considerably affected by the size of the particles. Again, far more intimate mixing of solids can be achieved if the particle size is small.
Also, blender is very much important because domestically it aids both the grinding and blending of the material at the same time. It is a very fast process which have substituted the use of manually operated grinding machine due to its high speed, easy to operate/handle, portable etc.

Construction Of A Blender:
A blender is a common kitchen appliance used for mixing, blending, and pureeing ingredients. It consists of several key components that work together to perform these tasks. Here’s an overview of the construction of a typical countertop blender:
Base Unit: The base unit houses the motor that powers the blender. It is usually made of durable materials like plastic or metal and contains the control panel, which includes buttons or knobs for various blending speeds and settings. Some advanced blenders may also have digital displays and programmable settings.
Motor: The motor is the heart of the blender and provides the power needed to rotate the blades. Blender motors are typically electric and vary in power from 300 to 1500 watts, depending on the model and intended use. High-powered motors are capable of handling tough ingredients and crushing ice.
Blades: Blenders have a set of sharp, rotating blades at the bottom of the blending container. These blades can be made of stainless steel or other durable materials. They come in various shapes and configurations, such as four-pronged or six-pronged designs, to efficiently blend different types of ingredients.
Blending Container: The blending container, often made of glass, plastic, or stainless steel, holds the ingredients being blended. It typically has a removable lid with a vent for steam release and a secure sealing mechanism to prevent leaks. The container may come in various sizes, from small personal cups to larger pitchers.
Gasket and Seals: To prevent leaks and ensure a tight fit between the blending container and the base unit, blenders often include gaskets and seals. These rubber or silicone components create a seal when the container is placed on the base, preventing liquids from spilling onto the motor or countertop.
Controls: The control panel on the base unit allows the user to operate the blender. It includes buttons or knobs for adjusting blending speed, pulse functions, and preset blending programs. More advanced blenders may have additional features like timers and pre-programmed settings for specific tasks, such as making smoothies, soups, or sauces.
Safety Features: Many blenders are equipped with safety features, such as overload protection, which shuts off the motor if it becomes overloaded or overheated. Some blenders also have interlocking mechanisms to ensure that the blending container is properly secured before the motor can operate.
Power Cord and Plug: The power cord is typically located at the base of the blender and connects to an electrical outlet. It provides the necessary electrical connection to power the blender.
Base Feet: The base unit often has rubber or suction-cup feet to provide stability and prevent the blender from moving or vibrating excessively during operation.
Optional Accessories: Some blenders come with additional accessories like tamper sticks for pushing down ingredients, extra blending containers, or specialized blades for specific tasks.
When using a blender, it’s important to follow the manufacturer’s instructions for assembly, operation, and maintenance to ensure safe and efficient blending. Regular cleaning and proper care of the blender’s components, such as the blades and sealing gaskets, are essential for its longevity and performance.
