INTRODUCTION
Engineering design is the method that engineers use to identify and solve problems. It has
been described and mapped out in many ways. This powerful approach to problem solving is
flexible enough to work in almost any situation. Engineers learn important information about
both the problem and possible solutions at each step or phase of the process. This process is
often done in small teams that include people with different kinds of knowledge and experience.
Various stages of the design process can involve a significant amount of time spent on locating
information and research. Consideration should be given to the existing applicable literature,
problems and successes associated with existing solutions, costs, and marketplace needs. The
source of information should be relevant, including existing solutions. Reverse engineering can
be an effective technique if other solutions are available on the market.

Student Name: V.Suhandan Guide Name: Prof. N. RAJAN, Associate Professor,
Funded by: MSME, New Delhi Amount Sanctioned: Rs. 6,25,000/-
Introduction
Cryogenic grinding is a method of powdering spices without loosing its aroma.
Temperatures ranging from -70°C to -200°C.
The spices are frozen with liquid nitrogen before they are being ground.
This process does not damage or alter the chemical composition of the spices in any way.
Theme of the Project
• Existing the cryogenic grinding is not used for ginger, garlic etc.
• Hence this project work is applied to grind the ginger to get
– fine dry powder
– without losing its characteristics
– Can be stored for longer period of time without adding any preservative
DRAWBACK OF CONVENTIONAL GRINDING
Clogging and gumming of the mill.
Loss of etheric oil.
Oxidation and related degradation.
Loss of aroma
OBJECTIVES
To retain the volatile components of the spices
To obtain maximum yield
To increase the product life
SEQUENCE OF PROCESSES
The spice to be ground is cleaned manually and fed in to the hopper.
From the outlet of the hopper the spice enters in to the vibratory feeder.
It is positioned with a small inclination towards the entry of the helical screw conveyor.
The speed of screw conveyor is reduced through reduction pulley.
Speed of the screw conveyor is 10 rpm for feed rate of 12kg/hr.
The liquid nitrogen is passed through the pre-cooler unit.
The spice is allowed to enter into the grinder after passing through the pre-cooler.
The grinding takes place at the pre-decided temperature in the range of -200°C to -70°C.
Spice gets crushed between the studs and comes out through an optional sieve as a ground
product.
The flow rate of liquid nitrogen is adjusted by the valve in the transfer line.
The powder is collected at chute and the nitrogen vapour is let out.

TEA LEAF CUTTING MACHINE
STUDENT NAME: HARISH, MECHANICAL
MENTOR NAME: Prof. S.RAJA
Tea cultivation in India has a long history in application of traditional system of medicine as
well as for consumption.Tea is a major beverage in India. It is considered as the second
cheapest drink after water.
India and China are the largest producers as well as the consumers of tea. 70% of tea produced
in India is consumed in India itself. Tea is grown in places having rain in most of the years
Tea bushes will reach up to thirty feet. This makes the harvesting difficult. In tea farming the
height of the bushes are maintained at a comfortable height for easy plucking of the leaves and
buds
Pruning the plants in comfortable heights regularly train the plants to produce leaves tightly
around the area easily accessible by hand.
Tea manufacturing is done by processing tea leaves. The tea leaves plucked from the plant and
taken to the factory where it is processed.
For good quality tea only the buds are to be plucked and processed. The shortage of labour and
the increase in wages made the management to think of an alternate method of harvesting the
leaves
Tea leaf harvesting is mainly done by the plucking of leaves manually. An experienced person
can pluck 40 kg per day, by using cutting scissors it can be up to 90 kg. Tea leaf cutting
machine is having double efficiency, it can pluck up to 180 kg per day
The machine operation is very simple and can be handled by a single person. Since India is one
of the major producers of tea in the world, tea leaves harvesting machine will have an
important role in improving the tea production
A tea leaf harvesting machine is a device used for easy harvesting of tea leaves with minimum
number of labors. Machine is so compact compared to existing models. Tea leaf cutting
machine helps in increasing output rate of tea harvesting with reduced man power

PARABOLIC SOLAR COOKER
STUDENT NAME: GAUTHAM KUMAR, MECHNAICAL
MENTOR: Prof. V.K.KRISHNAN
This project is to overcome the growing demand of energy. For our non-renewable sources of
energy are limited, we are trying to use the renewable source to cook.
Anodized aluminium sheet is used to construct a parabolic structure that concentrated the SUN
LIGHT to produce heat energy and this energy is used for cooking.
The sun light falls on the earth, it is transformed into heat by any surface or material, it the
atmosphere, soil, buildings, or even the furniture in front of a window.
This heat also drives the world's weather systems including wind, rain and river flow. Through
photosynthesis, plants also turn solar energy into new growth.
Anodizing is the process of coating a metal with its oxide. The oxide of Aluminium is
extremely hard and corrosion free so it is coated on aluminium to make it durable.
A parabolic concentrator is made in such a way that it could focus the sun light to generate
heat. It is made up of Anodized Aluminium because it is a good reflector, easy to install, low
cost and very much durable.

MILEAGE PROMOTER GEARS (MPG)
Funded by MSME, Government of India, New Delhi, Rs 6.27 lakhs
Student: S.Alagappan, Automobile Engg
Mentor: Dr.A.Nagappan, Principal
For the improvement in fuel efficiency / increasing the mileage and performance, normal gear
system is used in our regular use by changing the gears in a simple ratio. Usually if the gear size is
reduced the torque will be decreased proportionally. But in this project, the torque is trade offbetween
the mileage and speed. This project uses a simple gear transmission kit which drastically improves the
performance, speed and mileage of the vehicle. This saves a huge amount of fuel and provides a
smooth drive. In this project, gears with special transmission system is modified which can be used in
two wheeler vehicles.
The kit increases the mileagein any two wheeler vehicle. It is economic and has many
environmental advantages. Hence the main uniqueness of this innovation is promoting mileage, and
fuel economy using gears with compensating of torque.

ROOM TEMPERATURE
NAME OF THE STUDENT : Muhammad Arafath. A, IV/MECHANCAL
MENTOR:Prof. N.RAJAN, Asso.Prof/MECH
Scope of work The vacuum freeze drying method can prolong the storage time and maintain the nutrients of
the easily oxidized materials, food, agricultural products and medicinal drugs.
Therefore, vacuum freeze drying are widely used in the fields, such as agriculture (vacuum
freeze drying of vegetables, melons and fruits), food industry (vacuum package and vacuum
drying of fast food), chemical industry (drying of the powdery chemical agents) and biological
pharmaceutical products (freeze drying of hormones, antibiotics, blood preparations, medicine
for examination, vitamin agents and blood serum.
Project Brief:
It is a method utilizing both vacuum and freeze procedures to allow the moisture to
sublimate under the vacuum state, so as to form dry materials.
The biological and chemical properties of the materials after freeze drying remain the same
and their volume reduce slightly; however, their texture presents a loose and porous state.
Due to the lowered moisture content, the materials are harder to deteriorate by oxidation,
able to inhibit bacteria propagation and convenient for long-term storage.
Objective:
1. To prolong the storage time of the easily oxidized materials, food, agricultural products and
medicinal drugs
2. To maintain the nutrients of the easily oxidized materials, food, agricultural products and
medicinal drugs by vacuum freeze drying method.
What is available in market?
Presently the fruits are available in market in its original form, which has to be preserve
in refrigerated condition where it can be prolonged for few days.
The farmers are finding it difficult to preserve their fruits and to earn money for their
products.
What value it would add to market?
In food processing and agriculture, the vacuum freeze drying technology could prevent the
loss of nutrients in food and maintain good appearances and colors.
Observed under an electron microscope, the cell appearance is intact after drying.
What is the market potential?
Vacuum freeze drying is suitable for processing nutritious dry food due to its
antioxygenation and is able to produce a better quality when used in porous material.
In the drying process, the parameters of condenser temperature, shelf temperature and
chamber pressure are controlled directly, where the shelf temperature control affects the
moisture sublimation rate directly.

Title: Structural characterisation of nano-crystalline NiTi elemental powders formed by
mechanical alloying process
In the present work, the effect of milling time (0, 5, 10, 15 and 20 h) of mechanical alloying
method was investigated on structural characteristics, chemical compositions and microhardness of
Nickel Titanium elemental powder at equal weight atomic condition. The powder morphology and
reduction of crystalline size with increasing milling time was ensured by scanning electron microscopy
(SEM)as well as distribution of particle size at each level of milling was evaluated using particle size
analysis (PSA). At the initial stages (0 and 5 hr), the lamellar structure was perceived further nano-
crystalline size reduction was occurred at the final stage (20hr) of milling. The space between the
lamella structures reduces with milling time further formation of granular shape revealed in SEM
analysis.The presented phases and structural characteristics of milled powders were assessed through
X-ray diffraction analysis. Influence of milling time on hardness of NiTi pellets that prepared by
compacting was evaluated using Vickers hardness analysis. The linear increment of hardness was
observed with increasing milling time that produces nano-crystalline materials. According to the
results, nano-crystalline NiTi elements were formed at higher milling time which leads to increase the
hardness and formation of slenderer particles.

Title: Design and development smart wing for commercial and military aircraft
Nowadays, smart structure plays an important role in flying vehicles. In military aircrafts need
to be quick operations like lifting, yawing and rolling. In commercial aircraft when it fly very long
distance, which covers various atmospheric conditions like temperature, pressure, humidity, etc.. Due
this variation of atmospheric condition the materials are affected in the vehicle structure. To avoid the
stress generated due to variation of atmospheric condition the structure of aircraft may be smart
materials are used shape memory materials and shape memory alloys. In any aircraft control surfaces
are plays an important role when it fly. In the current technology provides only jointed moveable parts
like flops, winglets, slots and rudder. Which are all increase the drag force. Due to increasing drag
force the total operating costs are increases, quick response may be low and less human comfort
(vibration and noise). To increase the human comfort, safety and reduce the operating by reduce drag
force; we may go for integrated movable parts by using smart materials and smart structures.

Investigation of Machining Parameters on Anisotropic Structure of the Metal Matrix
Composites Al7075 through Electro Chemical Machining
AREA OF RESEARCH :ELECTRO CHEMICAL MACHING
Electrochemical Machining has wide application in the specialized fields such as aerospace and
defense industries. Aluminum 7075 composite is considered in this study because it finds applications
in die and mould making industries for making prototype models. In this research the machining of the
Al 7075, blind holes were drilled on plain surface (i.e. X – Direction) and on the side surface (i.e. Y –
Direction) using the ECM has been studied. Initially the Al 7075 composite was machined by varying
the parameters like the concentration of the electrolyte (Na NO3) at room temperature, machine input
voltage and the machine duty cycle and the frequency of the machine was kept at a constant value of
50 Hz. Then again the Al 7075 composite was machined by varying the machine input voltage,
machine duty cycle and concentration of electrolyte (Na No3+ concentrated H2SO4) and a constant
machine frequency of 50Hz. Also an indirect method of heating the electrolyte by using Infra Red light
source was used to improve the machinability. The blind holes were drilled in Aluminum 7075 by both
the experimental setups. Then blind holes were scanned in the Scanning Electron Microscope (SEM)
and the images were analyzed. The effect of the machining parameters on the depth of the blind hole
and the respective surface finish was studied. After comparing both the experiment results it is evident
that the influence of Infra Red light on heating the electrolyte and addition of concentrated H2SO4

Effect of Post Weld Heat Treatment, Tool Rotational Speed And Pin
Profile On Metallurgical And Mechanical Properties of Friction Stir
Welded Aluminium Alloy Joints
Literature review revealed that, the friction stir tool rotational speed and the profile of pin have
large influence on the metallurgical and mechanical properties of friction stir welded metals and metal
matrix Welded joints. Further literature also reported that the post welded heat treatment has
considerable influence on the mechanical properties in general and tensile strength properties in
particular of friction stir welded metal and metal matrix joints. The influence of above mentioned
parameters are separately reported in the literature. An attempt is made in this paper to study the
overall influence of post weld heat treatment, tool rotational speed and pin profile on the metallurgical
and mechanical properties of stir welded metal and metal matrix joints. A specific case of friction stir
welded AA6061 aluminum alloy joints were considered for above studies. Hot rolled plates of 6-mm
thick of above aluminium alloy was chosen and the friction stir welded joints were fabricated. Three
tool rotational speeds of 600 rpm, 950 rpm and 1300 rpm, and five different tool pin profiles of straight
square (SS), straight hexagon (SH), straight octagon (SO), tapered square (TS), and tapered octagon
(TO) were selected for the study. The post weld heat treatment consists of solution treatment, artificial
aging treatment and a combination of both. Microstructures of the welded joints were analyzed using
optical microscopy and transmission electron microscopy. Three different regions namely unmixed
region, mechanically mixed region and mixed flow region were observed in the weld zone. Further the
tensile properties such as yield strength, tensile strength, elongation and joint efficiency were
evaluated. The above experiments were conducted for each pin profile (5 profiles) and for each tool
rotation speed (3 speeds). It has been concluded that a simple artificial aging treatment was found to be
more beneficial than other treatment methods to enhance the tensile properties (210 MPa – Table 2) of
the friction stir-welded AA6061 aluminum alloy joints. Further the tool rotational speed and pin
profile considerably influenced the microstructure and tensile strength of the joints. The joint which
was fabricated using tool rotational speed of 950 rpm and straight square pin profile yielded highest
tensile strength of 273 MPa.

GEOMETRICAL DESIGN AND EXPERIMENTAL INVESTIGATION OF
UNDERACTUATED ROBOTIC HAND FOR MOTION AND GRASP FORCE
AUGMENTATION
In usual practice complex tasks like grasping irregular objects are easy for human beings, but it
is very difficult for robotic grasping. Through the adaptive nature of fingers, it can impart correct
contact forces so that problem of material damage is cleared from the root. Thus, the need for versatile
gripper is indeed necessary to create an adaptable grasping tool. This adaptive strategy promises the
wide range of grasping and effective contact force to the object. The term underactuation means ‘the
number of actuators, less than the degrees of freedom’. Unique characteristics of underactuated gripper
are that it can adjust depending on the shape and size of the objects. Practically underactuation
technique is difficult to apply as it requires more external force and torque for its mechanical system.
In order to eradicate this difficulty various researches are going on in the field of kinematics,
transmission capability, parallelogram mechanism, etc. It has some disadvantages like complicated
kinematic, less workspace and motion constraints. An important area in which research work is
moving ahead is the relationship between input torque exerted by the finger and output contact force
exerted on the phalanges. Problem towards the grasping of unshaped objects in unstructured
environments creates stress among all researchers. The solution for this can be developed by creating
versatile hand, which adapts to irregular shapes. It has totally 12 degrees of freedom actuated by single
actuator. The 9 degrees of freedom from three fingers, each finger has 3 degrees of freedom and rest
three degrees of freedom for the orientation of the fingers. Here an underactuated gripper is designed
with scaled up of 1.5 times of an average human hand. Pending patent covers the adaptive nature of
fingers and the reconfiguration ability. It is used on unstructured environments with different size and
shapes. The advancement of this research includes the addition of tactile sensors for the development
and control of the grippers for industrial and space application.

TITLE: Analysis of a wet cooling tower coupled with a desalination plant for fresh water yield
The scarcity of clean water resources and the need for supplementary water supplies is already
significant in many arid regions of the world and will be increasingly vital in the future. Many arid
areas simply do not have fresh water resources in the form of surface water such as lakes, ponds and
rivers. They may have only limited underground water resources; some are becoming more briny as
extraction of water from the aquifers continues. It is estimated that some 35% of the world’s irrigated
areas suffer from salinity problems and remediation is seen to be extremely costly. A desalination plant
is coupled with wet-cooling tower to utilize the water vapour (plume) from the top of cooling tower for
the fresh water yield by a designed water cooled condenser. From the cooling towers, lot of plume
carries heat energy is wasted and an idea behind this research focuses on diverting the plume to a
condenser through the ducts. The water vapour is condensed by the condenser,and then the fresh water
is pumped out with help of a positive displacement pump. A theoretical analysis is made by mass,
energy equations considering desalination system with the cooling tower to get fresh water yield. The
important parameters which affect the performance of the plant such as condenser flow rate, condenser
temperature, water vapour flow rate, water vapour temperature, cooling load, mass flowrate of water
and air, range and effectiveness through the tower have been considered to find out the maximum fresh
water yield (lps). The theoretical results have been validated with the experimental results available in
literatures. In this paper, a detailed design of a condenser and a theoretical analysis of the desalination
plant coupled with cooling tower to get fresh water is presented. With help of the results from analysis,
the power plant having cooling towers with the capacity 330 MW and 840 MW coupled with
desalination plant were analyzed
