1.1 INTRODUCTION
Milk production, in most of the countries particularly, developing countries, is confined
to rural/hinterland areas; while demand for milk and dairy products is mostly urban
in nature due to obvious reasons. Availability of inputs required for production of
milk is cheaply and conveniently available in rural areas, whereas densely populated
potential consumers are in urban areas. In addition, rural population, in general, face
lot of marketing problems due to scanty and scattered nature of milk production,
habitants and unavailability of proper infrastructure. Hence, milk has to be collected,
transported and marketed from villages to towns/cities for better return.
The milk collection system, chosen must reflect the local conditions in terms of
technical competency, cost, infrastructure and climate. Milk collection from producers
through collection points is done mostly in rural areas with a large number of small
suppliers and thus, eliminates a need for their own chilling and storage facilities.
Collection points must comply with the same hygienic requirements as the dairies
in addition to infra-structural facilities of quick transportation. In no case, milk after
milking should take more than 4 hours, particularly in temperate countries, to reach
to a point where it is chilled promptly to less than 4 °C.
i. Climatic Conditions
Climatic conditions like temperature and humidity with sharp seasonal variations
play an important role in planning a suitable milk collection system. The climatic
conditions of a centre or area remain persistent which cannot be changed by
human being at large. Milk collection structural requirements of a tropical country
will be altogether different from that of cold one. High climatic temperature and
humidity conditions are very much conducive for the growth of micro-organisms.
Sharp seasonal variations also lead to unpredictable situation for an established
collection system to compete. Special components are needed in such conditions to
prevent milk spoilage. Usually, a chilling component needs to be installed at collection
point, if not done at production point, to bring down the temperature of milk to
below 40C within 4 hours of after milking. Therefore, a milk collection system must
always be well adapted keeping in view the climatic conditions of the locality and
region.
The quality of milk reaching dairy is a deciding factor for manufacturing a product.
The collection structure is decided on the basic of types of products to be prepared
in the dairy.

i. Objectives
Milk collection system is organized with an objective to collect sufficient quantity
of milk for processing plant and to ensure: 7
Milk Reception accurate measurement of producers’ deliveries,
receipt of unadulterated, clean, hygienic and good quality milk.
regular payment to producers and giving incentive for quality production.
economic collection and efficient transportation to dairy plant.
ii. Steps
To organize a good milk collection system, the following steps are considered:
In second type, a more detailed comprehensive survey is carried out to ensure the
worthwhile location of a collection point. On the basis of number of milkmilch
animals, the number of potential producers is established; current milk production
and products made are estimated and likely potential in association of other
agricultural activities is assessed. A meeting of potential producers may be called
and possibility to form a producers’ cooperative or association of milk suppliers
should be discussed.
Deciding a milk collection route: In most cases, sending milk directly from
collection centre to main dairy or chilling centre is neither convenient nor economical.
Hence, a proper route planning is done taking into account milk availability, permissible
route length, road access and village connectivity, and distance of collection points
from the site of chilling/dairy plant. The economic route design has a great impact
on the progress of milk shed, milk quality and procurement cost. Increase in the
cost of milk, on account of quality deterioration or less capacity utilization of
vehicle, has direct impact on the total cost. Hence, the following information are
needed in deciding a milk collection route:
Details of milk shed area with respect to number of collection points and pattern
of expected quality of milk to be collected throughout the year at individual
points.
Geographical map of the milk shed area indicating road, river and railways.
Distance map of collection centre and milk producing villages.
Availability of type of transport vehicles.
Expected minimum and maximum time required to carry milk by special route
vehicle to the chilling/dairy sites.
A large centre, might be having a refrigerated bulk tank and may employ several
staff under a manager. The number will depend on size of a unit and the range of
activities carried out for organizing any collection centre. Three important points
are:
Responsibilities and the tasks of these employees have to be clearly defined.
Proper training is provided in the form of short courses for a few days.
A close supervisory control: A group of centres will be placed under a manager
at the dairy, making regular visits and applying close supervisory control.
Operating stage at collection centre starts with reception of milk from the suppliers.
At this stage, milk is graded and tested for acceptance or rejection. Accepted milk
is measured, recorded, sampled and analysed for quantity and quality on which
suppliers are paid. The centre records should be carefully kept in duplicate with the
total checked at the dairy and any discrepancy carefully investigated. A record of
test results will also be kept. Check tests at the dairy may be carried out periodically
and comparisons are made with individual results.
The milk, once accepted, is stored, perhaps only for an hour or so prior to dispatch.
Milk should be kept in the shade in water cooling system or in a large centre, where
available, refrigerated storage is done. The supplies are then dispatched to the
dairy/chilling centre. Transportation schedules should be carefully planned to minimize
time and cost.
Cleanliness of the containers used for milking, carrying, storage, and measuring,
etc. should be strictly maintained. Chemicals and detergents may be supplied by the
organization.
Supervision and control: Supervision and control of the collection centres include
supervisory visit, check measurement, testing and audit.
Five to fifteen collection centres are grouped under a field supervisor, working
under procurement manager. The field supervisor will visit each centre unannounced
at least two or three times a month to supervise a daily collection, review procedures
and check stocks, records, any cash and accounts. Periodic meetings of producers
may be conducted and complaint resolved. The field supervisor may also be
responsible for building up an area, organizing new collection points.
Supervision and control will also be carried out through the continuous surveillance
of the physical records of the producers’ supplies, deliveries and test results. Any
anomalies that are perceived would immediately be investigated. Control will also
be applied through financial records, costing and audit. Costing give a check on
business efficiency with comparison being made among centres. Regular audit is
vital to ensure there is no misuse of funds.
Direct from the producer: The individual producer brings milk and delivers to the
dairy plant independently. This practice generally suits the large producers located
near the processing plant. There is no obligation of any kind on either side.
The processor is in daily contact with the milk producers. Quality control can be
performed in the presence of the producer. Adulterations can be dealt with in the
presence of suppliers. The relative nearness and personal contact between producers
and processors is excellent. Additional job opportunities among rural people can be
created.
Dairy has the right to fix the price for milk. Generally low price is offered to
producers. Milk producers are normally exploited. Dairy may deny from taking the
milk on various grounds. There is no assured market for the milk throughout the
year. The dairy because of seasonal variations may not accept all the milk supplied
by the producers. Producers do not get incentive for increasing milk production.
Neither facilities to increase milk production are provided by dairy nor social and
economic needs are taken care of. The profits earned by the dairy are not shared
with milk producers.
Through middlemen: The producers, normally in our countries, are having one or
two milch animals. The milk is produced for the farmer’s family and the surplus
is sold locally or converted into a product. Under this situation, a dealer system
usually arises in which a middleman collects the surplus milk, carries it to the
10
processor or to a market in nearby villages or towns and then sells it. Dairy plants Milk Collection and
Transportation
has no direct contact with the actual producers directly. The traditional middleman
acts as agent between the dairy plant and small milk producers. Sometimes, milk
producers are given loan for purchase of milch animals with the agreement that the
milk produced will have to be sold to the lender only on his fixed price. Apparently,
it seems to be simple and flexible system. It is economical as head load, shoulder
sling, bicycle, motorcycle etc. are used as mode of transportation. It saves time of
small milk producers/suppliers. Milk is usually of poor quality. More proximity of
using preservatives, neutralizer etc. Milk could be supplied to limited distance. Price
for the milk received by the producer is very low. Producers do not get any
incentive or help for milk production. Milk producer, generally, remains a debtor.
Through agent or contractors: Some dairies enter into an agreement with the
authorized agents/contractors for the supply of certain quantity of milk for a specific
period. Normally, the price for the milk, its quality and quantity in different seasons
are mutually agreed upon. Other details such as mode of payment, timings,
transportation of milk, settlement of dispute if any and penalties for failure, etc. are
decided at the time of making agreement. Contractors make their own arrangement
to collect, chill and transport the milk in cans, tankers, bulk tanks, etc. by their own
vehicles. Dairy is no way concerned with milk production and management of milk
collection, transportation and incurring expenses on it. Dairy has not to deal with
large number of producers but only a few contractors.
Milk producers are, invariably, exploited by the contractors and the dairy as well.
Quality of milk, in general, is poor, adulterated and fabricated. Once becoming
dependent on the supply of milk by contractors, dairy yields to their dictat. Producers
get very low price for milk and profits are taken by the contractors. Often milk
producers remain debtor to the agent and they do not have freedom to sell their
produce elsewhere. No facilities for increasing milk production nor for the social
enlistment are provided. This system of milk procurement encourages red tapism/
corruption.
Unlike the other systems of procurement, the milk producer is the owner of the
dairy. He has the right to decide the price of milk and also to get the share of profit
made by the dairy. This system gives self-reliance to the producers for solving their
problems in a collective manner. This is a foolproof system to eliminate all the
demerits of other types of milk collection.
i. Materials of Construction/Fabrication
Wood, plastics, porcelain, glass, metals etc. are used for fabricating different type
of milk containers of several uses (Table 1.1).
12
Table 1.1: Type of containers and their uses Milk Collection and
Transportation
At the end of the milking process, the herd’s milk is pooled into one or a few
containers. For this, milk cans, bulk tank, refrigerated or insulated vats/tanks with
lid to cover, and similar type of containers may be used. The following is the list
of equipment and containers used at organized farms:
Milking machine
Milking pail
Weight balance, platform type
Storage milk cans
Storage vat
Bulk storage tank
Can cooling system
Milk sampling and testing unit
Bulk tank cooler
Road bulk pick up tankers are used to transport milk from collection or collection-
cum-cooling centres. A tank may be equipped with a pump and hose, weighing
facilities or a flow meter, sample bottle with an in-built automatic sampling line.
Bulk pick up tankers are usually constructed with an insulation layer of cork,
polystyrene or mineral wool. The tanker may be refrigerated or simply insulated.

Milk Collection and
1.5 TRANSPORTATION OF RAW MILK Transportation
The dairy plants organize the collection and transportation of milk in its collection
area. Route plans need to be established and continuously optimized for an optimal
utilization of the transport facilities and keeping transport cost low. Some sorts of
transportation are also required to carry the milk from points of production to the
points of collection, pick up, chilling or processing.
i. Purpose
Milk being perishable commodity, it becomes necessary to transport the fresh raw
milk to the consumer or the chilling/processing plant within 4 hours of its production.
Thus, transportation becomes an integral part of milk collection system. An efficient
and suitable facility is selected on the basis of the raw milk collection as well as
regional requirements.
Geographical location: In hilly areas where roads are not developed, small quantity
of milk can be carried out on head for short distance and on shoulder sling for
comparatively longer distance and larger quantity. In places where river is to be
crossed, a boat and road in combination may be used.
Volume of milk: For small quantity and short distance head load, shoulder sling,
cycle, etc; for moderate quantities and longer distance motor cycle, cart, tri-wheeler,
etc. by road can be transported. If quantity of milk is large, milk in cans on truck
& lorries or in road/rail tankers for long distances can be carried.
Condition of road: Condition of road such as dusty, narrow, broken, having sharp
turnings, congestion, business, obstacles like railway crossing, etc. are also taken
into account in selecting a suitable vehicle for milk transportation.
Own vs. hired: Having own transportation system is too expensive and highly
cumbersome. Apart from the initial investment on vehicles, it involves a complete
section of maintenance and operational personnel. Even after involving a considerable
time, energy and money, the system is neither cost effective nor working satisfactory.
On the other hand, hired transport facilities are very effective and relieve the
management from several problems and evils. It is economical because of no or
low investment and maintenance expenses. The dairy has an agreement with the
owner of the vehicle regarding rate, mode and interval of payment, liabilities on
account of delays, spoilage of milk, accidents, pilferage during transit, change in the
quality due to any fault on his part, etc. Heavy penalties and recoveries are imposed
for any lapse on the part of the transporter.
15
Milk Reception iii. Methods
Generally following methods are being used in dairy industry:
Head load: Generally, producers carry milk on their head to nearby collection/
chilling/processing point. This is being practiced in villages to carry small quantity
(3 to 25 litres) of milk for short distances (3-8 km) to the collection point, specially
in hilly areas where there is no development of road.
Shoulder sling: Use is restricted to hilly areas or other areas where no other
means of transport is easily available. When the milk is slightly more (20 to 40
liters) and conveniently can not be carried on head, for little more distance (5 to
10 Km), this method is practiced.
Bullock cart: In villages where no road exists in real sense, bullock cart is used
to carry milk, if quantity is more (300–400 Kgs) and distance is to be covered
within 1 to 2 hours. It is very slow moving vehicle.
Tonga (Horse cart) : It is faster than bullock cart but it needs road to ply on and
carries comparatively less load (200-250 Kgs) for more distances (10-15 Kms).
Pack animal: Ponies, horses, donkeys and bullocks are usually employed to carry
40 to 80 Kgs to a distance of 5 to 10 Km. This method of transport is faster than
bullock cart but slower than tonga.
Bicycles: Bicycles are commonly and conveniently used to carry milk to the
collection centres, pick-up points and chilling/processing points. It is also used to
carry milk in unorganized sector by middlemen/agents/vendors to sell milk in the
accessible urban area. It is faster, more convenient and easily accessible to milk
producers/consumers home. About 40 litres (l) of milk for a distance of about 10-
15 Km can easily be transported.
Motor Cycle: Still heavier duty then bicycle can be taken to cover more than 15
Km and carry more than 100Kg of milk in very short time.
Auto rickshaw: It can carry more load than cycle, rickshaw/motor cycle.
Boat: Boat is used to cross-river. Normally, small boats carry about 200 l of milk
for short distances.
Motor trucks: Motor trucks carry milk in cans and bulk tanks to a load of 0.5 to
3.5 tons for more than 100 Km. With the improvement in road facilities and
construction of all season roads, motor trucks have been found most effective
means of transportation.
Railway wagon: Railway wagons are most dependable and economical for long
distance but less popular means of milk transportation. Railway wagon can carry
10 to 12 tons of load for more than 100 Km.
Road tanker: Insulated stainless steel tanks are mounted on road truck chesis for
bulk handling (3000 – 12000 l) and for long distance (100 to 1000 Km.) transportation.
The tanker may be divided into 2 to 3 equal capacity compartments with separate
outlets.
Rail tanker: Insulated and/or refrigerated stainless steel tanks are mounted on rail
truck/chesis of the capacity in the range of 10,000 to 50,000 l to transport milk for
a long distance 500 to 3000 Km or more.

The extent, structure, distance of the collection area and form of collection, determine Milk Collection and
Transportation
the selection of mode of transportation.
Type of Transport: Roadways, railways, waterways and air ways are the possible
types of transport. Sometimes combination of two or more can also be used for
transporting milk. In selecting suitability of a type of transport, volume of milk,
geographical location of the area, availability of facilities and ultimately the cost of
transportation are taken into account. A comparative advantages of can vs. tankers
and road vs. rail transport have been given in Table 1.2 and 1.3 respectively.
Type of milk collection system includes supply of milk to the processing plant
directly, through collection and/or chilling centres and through multi-stages of handling.
Varieties of containers, made of different materials and of various shape, size,
capacity and designs are used at different points of milk handling and processing.
