INTRODUCTION

Milk is widely considered as one of the most valuable and well-known Food. Milk is used as food by all age group. In industry has standard capacity of Milk processing and milk handling 1,000 – 5 Lac liters per day. Milk Processing plant can operate 20 hours in a day. Fat content Whole or full-fat milk contains about 3.5% fat Semi-skimmed contains about 1.7% fat Skimmed milk contains 0.1 to 0.3% fat Some supermarkets sell milk with a 1% fat content which has almost half the fat of semi-skimmed milk but retains a more creamy flavor. In India Organized(Private, Cooperatives & Govt.) and Unorganized Dairies.

SITE

The plant should be located as centrally as possible within a given milk-producing area, near a source of water, or in a place where water is available. The transportation facility must be nearer to the plant i.e. Road, Market connectivity. The site should be cool and well-ventilated. It always influenced by their environment The most important factor is availability of water. It should be remembered that on average five liters of water are required to process one liters of milk. Electricity and workers availability.

Site and requirement of Milk Processing Plant.

CIVIL WORK AND CONSTRUCTION

An unused building can be purchased or leased and adapted for milk processing operations. New building can be constructed. It is not uncommon to find in some remote milk-producing areas. The walls should be built of local stone and the inner walls lined with a lime-cement mixture for easy cleaning. The cement floor should have a 2 to 3 percent slope for draining water used in cleaning. Windows should be sufficient to provide adequate ventilation. Building size will of course depend on the quantity of milk received during the peak production period. An average quantity of milk which can be processed by a small-scale unit amounts to 100 to 500 liters per day.

PLANT SET UP

Plant set up. When civil work completed equipment are ready to install. The equipment needed to run the dairy processing plant depends on several factors. How much milk is to be collected ? How far and how scattered are the milk producers ? What kind of product is to be produced ? In the standard milk processing pattern, commencing with milk collection and ending with the sale of the dairy products.

OPERATIONS AND PRODUCTION

An unused building can be purchased or leased and adapted for milk processing operations. New building can be constructed. It is not uncommon to find in some remote milk-producing areas. Milk processing operations will take place far from urban consumption centers. In these areas the quantities of milk hardly exceed an average of 500 liters per day. The products made must be able to withstand long periods of transportation, often under difficult climatic conditions. Standardization: Standardization is an operation producing milk with a constant butterfat content through partial, manual skimming. The operation makes it possible to standardize the composition of the finished product and to set aside part of the cream for butter.

OPERATIONS AND PRODUCTION

Heat treatment: Pathogenic germs in milk are destroyed by heating the milk to a minimum temperature of 63°C for 30 minutes. Inoculation: Due to heat treatment, which destroys a large number of lactic bacteria, cheese or yoghurt-making requires the addition of lactic bacteria to the milk. These bacteria are selected according to the type of finished product required. Clotting: Milk changes from a liquid to a solid state through the use of a coagulant: rennet. Curd-Separation: In cheese-making, the milk after coagulation is cut and separated into a liquid whey, and cheese curd. Ripening: This phase of cheese-making allows cheese texture to become homogeneous and the aroma to develop.

OPERATIONS AND PRODUCTION

Churning: In this operation, cream is churned to produce a semi-solid product which becomes butter. Melting and emulsification: Defective cheeses are melted and emulsified with salts to obtain a solid consistency and, after cooling forms processed cheese.

COLLECTION

Stainless steal milking pails are often an improvement on the utensils commonly used. The producer should use small aluminum milk cans of 5–10 liter capacity for transporting the milk, while the collector should use 30–50 liter cans. If the milk needs to be collected, the following will be needed: the use of a bicycle, a 50 liter milk can, a graduated cylinder lacto-densitometer and a measuring pail.

PROCESSING

Reception: the following equipment is needed for the reception of milk brought in by producers themselves and by the collector: a milk scale and a pail. Storage: a milk funnel and 50 liter milk cans. Standardization/Cream separation: a manual cream separator has to be used to skim a portion of the milk received. Heat treatment: there are several possibilities for heat treatment, depending on the available power source. Under the least favorable circumstances, the sole available energy source is wood or peat. The best thing to use in this case is a “boiler/water bath” Cooling: the milk is cooled with the help of milk chillers.

PROCESSING

Clotting: The cheese vat can be of aluminum with a tap for draining the whey Pressing: different kinds of cheese (curd) presses can be made. The simplest press is made by placing weights or cement block on the molded cheese (curd) as shown in the following diagram:

PRODUCTS

Types of Milk : Pasteurized, Homogenized, Whole, Skimmed, Single Toned, Double Toned, Full Cream milk contain.

Pasteurized - Heated at high temperatures in order to the kill the harmful bacteria without losing out on the flavor or nutritional content of Milk.

Homogenized - Process where the fat globules in it are broken, which spreads the fat evenly, preventing the formation of the creamy layer on top. However, the fat content and other factors remain the same.

Skimmed - All the nutrients found in whole milk like the vitamins and minerals.

PRODUCTS

Whole – full cream milk is usually consumed by children, teenagers and body builders. Whole milk is called so because it contains all the milk fat found them. One glass of whole milk contains 3.5% milk fat, which provides about 150 calories. Whole milk is also creamier and full of flavor

Single Toned - obtained by adding skimmed milk powder and water to whole milk. It contains about 3.0% fat and toned milk restricts the body from absorbing cholesterol from the milk to minimum

Double Toned -obtained by adding skimmed milk power to whole milk and has about 1.5% fat content. Double toned milk is ideal for those trying to maintain weight as it keeps the calorie intake under check and aids weight loss.

PRODUCTS

Cream –the fat layer of milk is separated to make different types of cream.

Yogurt - a very popular dairy product made by the fermentation of milk by lactic acid bacteria.

Butter - is a water-in-oil emulsion made from 'cream by phase inversion.

Cheese - is made from curdled milk by removal of the whey part (liquidly part) and then ripening of the curd part (solids part) using particular microbial cultures.

Ice cream - It is another universally popular dairy product, made from milk of varying fat contents.

PRODUCTS

Paneer – The curds are drained in muslin or cheesecloth and the excess water is pressed out

Shrikhand - Shrikhand, yogurt is tied in a cotton cloth and left under pressure to drain

Ghee - Ghee is the pure butterfat left over after the milk solids and water are removed from butter.

Khoa - Made of either dried whole milk or milk thickened by heating in an open iron pan.

Lassi -  Lassi is a blend of yogurt, water, spices. Sweet Lassi, Mango Lassi & Bhang Lassi.
