INTRODUCTION

The Kolhapur Zilla Sahakari Dudh Utpadak Sangh Ltd., Kolhapur was
established on 16th March 1963 under Co-operative societies Act. It started with
collecting 700 liters of milk per day from 22 primary co-operative societies. The basic
function of the sangh was to procure the milk and supply it to the government dairy
which was located in Tarabai Park, Kolhapur. In 1978, the National Dairy Development
Board included Kolhapur District under Operation Flood area. The project was financed
by NDDB. Under this project a 2-lac liters / day capacity dairy plant was constructed at
Gokul Shirgaon, Kolhapur. At Gadhinglaj and Bidri chilling centers of 75,000 & 50,000
liters /day capacity were also constructed under the project. In 1985, the Government
milk scheme, Kolhapur was handed over to Kolhapur Zilla Sahakari Dudh Utpadak
Sangh. During 1985 the average milk procurement was 1,14,836 liters/day with 676
village level primary co-operative societies. The production of milk in Kolhapur Zilla
Sahakari Dudh Utpadak Sangh started in 1985 and after one year the production of milk
products was started. The chilling centers were established at Lignnur, Borewadi,
Tawarewadi and Gogave having capacity of 1.25LLPD 1.00 LLPD, 1.00 LLPD & 0.50
LLPD respectively. In 1987 packing unit, having a capacity of 4.00 LLPD was
constructed at Vashi Mumbai. In 1993, another packing unit of capacity 0.50 LLPD was
started in Manjiri (Pune).

EKOMILK ULTRA PRO MILK ANALYZER :

Working Principle :
The instrument is ideally suited for the village milk collection centers, milk chilling
centres etc. and milk testing laboratories. The Ultrasonic Electronic Milk Analyser works
on the principle of Ultrsonics. The signals allowed to pass through the sample are
measured digitally for accurate display. In order to ensure high quality of raw milk
received from the villages, Dudh sangh has supplied Milko Testers to the village Dairy
Co-operatives. The milko Testers are electronically operated machines to determine the
fat percentage of the milk. The milk supplied by every individual milk producer is tested
before acceptance and the payment is made based on the quality of milk.

FEATURES :
 Simple in use and maintenance, reliable and automated;
 Multi-parameter milk analysis;
 Customer available readjustment of measurement accuracy;
 Fast and low cost analysis
 No acid or other chemicals are used;

GENERATORS :

WORKING :
Generator is a machine that converts mechanical energy into electrical energy. It
works based on principle of faraday law of electromagnetic induction. The faradays law
states that whenever a conductor is placed in a varying magnetic field, EMF is induced
and this induced EMF is equal to the rate of change of flux linkages. This EMF can be
generated when there is either relative space or relative time variation between the
conductor and magnetic field. So the important element

Generators are basically coils of electric conductors, normally copper wire, that are
tightly wound onto a metal core and are mounted to turn around inside an exhibit of large
magnets. An electric conductor moves through a magnetic field, the magnetism will
interface with the electrons in the conductor to induce a flow of electrical current inside
it.

Conservator Tank of a Transformer

This is a cylindrical tank mounted on supporting structure on the roof the transformer
main tank. The main function of conservator tank of transformer is to provide adequate
space for expansion of oil inside the transformer.

Function of Conservator Tank of a Transformer

When transformer is loaded and when ambient temperature rises, the volume of oil
inside transformer increases. A conservator tank of transformer provides adequate
space to this expanded transformer oil. It also acts as a reservoir for transformer
insulating oil.

Construction of Conservator Tank

This is a cylindrical shaped oil container closed from both ends. One large inspection
cover is provided on either side of the container to facilitate maintenance and cleaning
inside of the conservator.

Conservator pipe, i.e. pipe comes from main transformer tank, is projected inside the
conservator from bottom portion. Head of the conservator pipe inside the conservator
is provided with a cap. This pipe is projected as well as provided with a cap because this
design prevent oil sludge and sediment to enter into main tank from conservator.
Generally silica gel breather fixing pipe enters into the conservator from top. If it enters
from bottom, it should be projected well above the level of oil inside the conservator.
This arrangement ensure that oil does not enter the silica gel breather even at highest
operating level.

Working of Conservator Tank

When volume of transformer insulating oil increases due to load and ambient
temperature, the vacant space above the oil level inside the conservator is partially
occupied by the expanded oil. Consequently, corresponding quantity of air of that space
is pushed away through breather. On other hand, when load of transformer decreases,
the transformer is switched off and when the ambient temperature decreases, the oil
inside the transformer contracts. This causes outside air to enter in the conservator
tank of transformer through silica gel breather.

Boiler

Generally, a steam boiler is a type of closed container, designed with steel for heating
the water to generate steam by some energy source like burning of fuel with eventually.
The vapor generated may be delivered at low-pressure for the industrial progression
work in sugar industries, cotton mills, and for generating steaming water that can be
utilized for heat up fixing at much low-force. The capacity of the boiler should have ten
liters of water and the working pressure must be 3.4 Kgf/cm2 (kilogram-force). This
article discusses what is a steam boiler and its types used in power stations for
generating steam.

The Function of Steam Boiler

The main function of a steam boiler is to producing, storing and troubling the vapor. The
liquid contained boiler is nothing but a shell and the heat energy produced while burning
of fuel will be moved to water, and then it converts into steam at the required pressure as
well as temperature.

The main conditions of this boiler mainly include the water container should lock very
carefully. The vapor of water should be supplied in the preferred conditions namely,
quality, rate, pressure, and temperature.

The main working principle of a steam boiler is easy. This boiler is one type of closed
device in the shape of a cylindrical. The capacity of the boiler to have steam, as well as
water is sufficient.

Needless to say that the Sun is the biggest source of renewable energy for the Earth. The fact is that even
though the earth receives only a part of the energy generated by the Sun (i.e. Solar energy), that part of
solar energy is also tremendously huge. The Earth receives solar energy in the form of light and heat.
But in today's world, the words 'power' and 'energy' are leaned more towards 'electricity'. This article
explains how electricity is harvested from the solar energy and how it is utilized.

How solar power works?

Electrical energy can be harvested from solar power by means of either photovoltaics or concentrated
solar power systems.

Photovoltaics (PV)

Photovoltaics directly convert solar energy into electricity. They work on the principle of the
photovoltaic effect. When certain materials are exposed to light, they absorb photons and release free
electrons. This phenomenon is called as the photoelectric effect. Photovoltaic effect is a method of
producing direct current electricity based on the principle of the photoelectric effect.

Based on the principle of photovoltaic effect, solar cells or photovoltaic cells are made. They convert
sunlight into direct current (DC) electricity. But, a single photovoltaic cell does not produce enough
amount of electricity. Therefore, a number of photovoltaic cells are mounted on a supporting frame and
are electrically connected to each other to form a photovoltaic module or solar panel. Commonly
available solar panels range from several hundred watts (say 100 watts) up to few kilowatts (ever heard
of a 5kW solar panel?). They are available in different sizes and different price ranges. Solar panels or
modules are designed to supply electric power at a certain voltage (say 12v), but the current they
produce is directly dependent on the incident light. As of now it is clear that photovoltaic modules
produce DC electricity. But, for most of the times we require AC power and, hence, solar power system
consists of an inverter too.
