1. INTRODUCTION

1.1 INTRODUCTION
In the present era of the 21st century the major problem in developing countries are the
substantial problems arising due to organic waste. Being an agriculture dependent country
India produces a large amount of organic residues which then leads to the several problems
of its disposal. These organic residues prevail upon the problems such as incineration,
landfills, soil erosion, bad odor, air pollution and increase in carbon dioxide level in the
atmosphere. Thus we need to ensure an efficient alternative to these problems. We plan to
convert this organic waste into useful resources such as compost which adds on a considerable
value to our farming. In CSR journal, it is stated that “Indians waste as much food as the
whole of the United Kingdom consumes”. With over 1.3 billion people in a nation like India,
millions are still sleeping hungry. According to the United Nations development program,
about 40% of food which is produced is wasted in India. Government of India is working in
the direction of food waste management. The food waste in the kitchen being a part of food
waste remains unnoticed, this provides scope for “Organic food shredder”. This equipment
chops the kitchen waste in small pieces and hence makes it more suitable for compost making,
yeast is added as a catalyst in the process of composting.
There are different types of organic shredder. They can be classified as follows

1) Number of shaft [ single shaft / double shaft / multi shaft ]

2) Mode of operating [ manual / semi-automatic / fully automatic]
3) Use of energy [Electrical / mechanical /solar ]
4) Size [compact/ small/ huge]
5) Application [farm/ municipalities / domestic use ]

b) OWS-3 Organic Waste Shredder Machine

The Major advantage it has on dual shaft shredders is, it can give comparatively
higher throughput at lower capital investment and motor HP. Also even 1 HP OWS
and process coconuts.
Advantages:
• over the similar design models in the market
• Cutting chamber can be opened easily without disturbing rotor bearings
• Controlled spray area output particles
• Sturdy stand and rugged body
• Base heavy design - Less vibrations and noise
• Least cost in the segment

Disadvantages:
• High speed operation - Noise during shredding, operator safety training
required
• Wear parts - Hammers, screen will gradually wear off and will require
replacement as per the machine usage.
• Jamming - long, fibrous items may get wound on rotter and can cause jam.
In such a case the cutting chamber needs to be open to remove the coiled material.
Also the feeding should be gradual. (We have added special feature so that the
chamber opening is made very simple than that in similar models in market)

2. LITERATURE REVIEW

There are various machines already present in the market for agricultural organic waste.
Here we are only focusing on household waste and producing compost enough for
household gardens. The product will be compact and could fit in any kitchen space. We
have read different research papers, and we noticed that the machines are bulky and are
bound for heavy usage. We noticed different types of mechanisms for shredding, we are
going to use a single shaft multi cutter mechanism which is most appropriate to our
applications.
2.1 P.B.Khope et al., Proposed the Design of experimental set-up for establishing empirical
relationship for chaff cutter energized by human powered flywheel motor. This machine used
to chop the forage into small pieces for easy consumption by the animals. In the human
powered flywheel motor concept, the bicycle mechanism for converting and transmitting
human energy through padding to rotational kinetic energy of flywheel is hereby proposed.
The energy stored in the flywheel can be used for the actual cutting process. [10]
2.2 Ajinkya S. Hande et al., in their research work carried out project on Methodology for
Design and Fabrication of Portable Organic waste chopping Machine. Organic waste is fed
uniformly through feeding drum and tray. Then the shaft rotated at 1440 rpm through electric
motor by means of pulleys makes the chopping drum to cut the waste by the effect of impact
shear obtained from the shearing blades. Then the cut pieces pass through the concave holes
of the sieve & come out of the machine. [1]
2.3 Mohamad Khatib Iqbal, proposed “Development of coconut leaves cutter ”A shredder
machine mainly consists of cutter, mounted on dual shaft, motor is attached at the base,
smaller pulley at the motor end gives drive with the help V-belt to bigger pulley which is
connected to gear. One gear will give drive to other gear, and Barrel rotates in the opposite
direction with the help of these gears. Shaft it rotates at 520 rpm at this time coconut leaves
fed into the hopper for high rotational speed of cutter assembly coconut leaves get convert
into powder. [6]
2.4 S Nithyananth et al. They have developed a Design of waste shredder machine. The waste
shredder a machine is an attachment as like a ploughing attachment. Shredder can be operated
with Tractor- power take off shaft. The power from the Tractor is transmitted to the assembly.
The assembly consists of one fixed blade and five circular blades. [7]

2.5 Ganesh U L, Vinod V Rampur, Ashok R Banagar their proposed organic portable shredder
machine capable of operating at rated speed of 700RPM and able to implement in agricultural
fields for developing a raw material for compost. The above machine is a prototype and can
be enhanced depending on requirement and can be integrated with vermin compost or in
generating any other organic fertilizers, since it has good cutting efficiency and chopping
them to a powder form. [4]
2.6 I.M.Sanjay Kumar, DR. T.R. Hemanth Kumar The developed model is simple, efficient,
requires less time and cost effective when compared to the existing available model.
Importance is given towards user friendly in operation and mainly towards safety. The
rotating elements like belt and pulley and gears are covered, so it is fully safety to operator.
The assembly was checked for its sturdiness and was found to be reliable. The overall
performance of shredder machine was satisfactory by considering the quantity of powder
produced with respect to time. [11]
2.7 Pavankumar S B, Sachin K R, Shankar R, Thyagaraja B, Dr. T. Madhusudhan they
conclude that atomize machine is better option to shred the organic waste instead of using
manual operated shredder. In this we designed the machine by considering the various factors
into consideration. The machine is made for small businessman, therefore the work carried
out by these machine is less. [5]
2.8 Arun K A, Arun P Unnikrishnan, Febins P M, Basil Bava, Sreerej T S, Rinto K Anto this
project is intended to empower the agricultural field. The main stages of the project can be
classified into 3 categories study design and analysis and at each categories there are so many
activities required to complete this project. Determine a specific set of crushing process
parameters and the corresponding crushing process forces to best represent a crushing
machine in the industry. Design a crushing machine which have high crushing rate at
minimum production cost based up on the design considerations and accessibility. [3]
2.9 Sreenivas H T, Sundeep Y, Ajay Krishna T M, Naveen Kumar K H, Dr. N Krishnamurthy
the machine will be ideal equipment for chopping the crop residues to obtain organic compost.
In the process of completion of the work our ideas and thought are development towards the
mechanisms and technologies of the equipment. Similarly we can say that for the purpose of
shredding the organic waste this is economical and ideal machine which can bring a drastic
change in the economic condition of farmers thereby improving their standard of living. [12]

4. PARTS DETAILS AND WORKING

4.1 Parts Details

4.1.1 FRAME

A frame is a structural system that supports other components of a physical construction or

steel frame that limits the construction's extent. The frame will be made of mild steel that will
provide strength to the frame. Dimension of the frame would be 250 X 100 X 200 mm
(L x B x H). The motor will be mounted on the frame. And the frame will provide the
structural support to the shredder.

4.1.2 HOPPER

A hopper is a pyramid or cone shaped container, to hold particular matter or flow of material.
Hoppers must be designed such that they are easy to load. More importantly, hoppers must
be designed such that they are easy to unload, while hopper is a funnel shaped container, also
feeder in the equipment. Through the hopper the feeded organic waste drops on the cutting
blades for further operations. . The hopper is inclined in such a way that the kitchen waste
which is to be inserted through the hopper will directly come in contact with the blades. The
hopper will be made of stainless steel as the moisture of the waste will not affect the fife of
the hopper giving sufficient strength. The hopper will be constructed in such a way that the
waste particle fall on the sides of the throat of the hopper so that the waste does not comes
out of the hopper. The outer dimension of the hopper would be 200 X 200 mm and the throat
dimensions would be 100 X 100 mm and the thickness of the stainless steel sheet would be
1.25 mm.

4.1.3 MOTOR

Gear motors are complete motive force systems consisting of an electric motor and a
reduction gear train integrated into one easy-to-mount and -configure package. This greatly
reduces the complexity and cost of designing and constructing power tools, machines and
appliances calling for high torque at relatively low shaft speed or RPM. Gear motors allow
the use of economical low-horsepower motors to provide great motive force at low speed
such as in lifts, winches, medical tables, jacks and robotics. There are many types of gear
motors: Parallel shaft gear motors, planetary gear motors, helical gears, spur gears.
This is 12V DC motor which has a gearbox of 50mm diameter. The planetary type gearbox
of this motor has a metal gears and a center shaft. The Shaft of the motor is loaded with
bearing for wear resistance and smooth operation.

Features:

1. Brushed permanent magnet DC motor

2. Variable speed and reversible
3. Planetary Gear Box

4.1.4 CUTTING BLADE

The cutter is made up of an Alloy Steel piece of diameter 90-mm, thickness of 5mm. The
cutter is bolted to a blade holder which is attached to the main shaft. Since the cutter is bolted
to the blade holder free movement of the blade is possible. Along the circumference of the
shaft 4 blade holders are attached. Along the length of the shaft 8 blade holders are attached
spacing 1.5 inch between each one of them. Therefore, the total number of blades is 10. The
blade would be face locked with the shaft so that is any hard piece breaks the blade than it’s
easy to repair or replace the blade. The blade would be 90 mm of diameter having its bore
diameter 20 mm and thickness of the blade would be 1.5 mm

4.1.5 SHAFT AND SHAFT COUPLING

4.1.5. A SHAFT
A shaft is rotating machine element, usually circular in cross section and which is used to
transmit power from one part to another part or from a machine which is a power producer to
power machine, which absorbs power. The various members such as cutting blades, gears and
pulley are mounted on it. Material used for the shaft is EN 8 steel.

Fig 4.1.5.a – Shaft

4.1.5. B SHAFT COUPLING

A coupling is a type of general purpose power transmission coupling that also can be used in
motion control applications. It is designed to transmit torque while damping system vibrations
and accommodating misalignment, which protects other components from damage. Jaw
couplings are composed of three parts which consist of two metallic hubs and an elastomer
insert called an element, but commonly referred to as a "spider". Considerations for elastomer
selection include ability to dampen vibration, ability to handle misalignment, operational
temperature range, speed of equipment, and chemical conditions. Jaw couplings are
considered "fail-safe" because, should the elastomer fail or wear away, the jaw coupling hub
teeth will mate, much like teeth on two gears, and continue to transmit torque.

Fig 4.1.5.b – Shaft Coupling

28
DESIGN AND FABRICATION OF ORGANIC WASTE SHREDDER

4.2 WORKING
The organic waste (fruit/vegetable peels and remains, tea etc.) through the hopper falls on the
cutting blades. A 24 V, electric supply is given to the DC motor which converts electric supply
to motive power. Further this motor power is transmitted to the shaft through coupling. The
rotation of blades causes a cutting and chopping action on the waste, after a fine chop it falls
down in the container. Now the chopped waste is ready to compost adding a little compost
and yeast will boost the process.
As due to rotation of the cutters, the feed will get thrown up, for that we are giving a slant
entrance that will send feed to a side of the throat, so the cutter rotational torque will be used
in the chopping and cutting. The output is collected in a bin kept at the bottom of the shredder.
The Material used for construction of the hopper would be stainless steel, while EN 8 steel
would be used for manufacturing of shaft on which the cutting blade would be mounted. The
blade will be face locked with the shaft so that it can be replaced or repaired, when any hard
particle is feeded while cutting operation can break the cutting blade. As we are using
shaft coupling to transfer motion of motor to shaft. We will require An AC to DC
converter that will give power to the motor for its working. Hopper and motor both will
be mounted on a frame, made up of mild steel

7. CONCLUSION AND FUTURE SCOPE

On-site food waste systems are alternatives to landfill disposal and can facilitate compliance
with the proposed waste ban. These systems can be used as an alternative or a complement to
off-site composting of food waste. While interviews with staff at facilities using these
technologies indicate general success at reducing the volume and weight of food waste
generated, a number of potential concerns also came to light. Many of these systems are
relatively new to the market and have not been thoroughly tested. While our findings suggest
that they can be a valuable component of an institutional food waste management program,
they also point to the need for careful planning and due diligence prior to purchase. For this
semester we have completed the design of different components that includes
calculations, CAD model and analysis. We used CREO 7.0 for CAD model and ANSYS
workbench for analysis of the shaft. For the next session we have manufacturing and
assembly of the components of the shredder.
The following are the important points drawn from our work:
• Machine cost is less compared to other shredder machine.
• Blades can be easily removable.
• Highly skilled labours are not required.

7.1 FUTURE SCOPE

1. By increasing the cutting speed the efficiency can be increased. Also by using more number
of cutting blades the output efficiency & productivity can be increased if required.
2. The machine can be made movable by providing wheels or tire to it which can move more
freely without any problem.
3. By increasing the size of the cutting chamber and power more amount of waste residue can
be continuously feed in the machine cutting chamber.
