Pollution Board certificate for milk processing

A milk processing unit processes raw milk through physical processes like pasteurisation, standardisation, homogenisation and packaging. Other subsequent stages of processing can be done within the processing unit to produce different dairy products like ghee, curd, cheese, ice cream, butter etc. After processing, when the milk is ready to be consumed, it is packaged and transported. Here the hygiene and quality of the product are paramount. Along with it, the management of waste generated by milk processing is also mandatory. Different techniques are implemented to treat raw milk into the desired product. Therefore, for the processing of milk in these units, a Pollution Control Board certificate is required before starting the processing. In this article, we will understand the step-by-step process to apply for a Pollution Board certificate for milk processing units.

Milk Processing Plants in India

Every stage of the processing is monitored for quality and hygiene and follows the standard operating procedure mandated by law. Different packaging, like cartons, glass, pouches, and bottles, are used to deliver the final product to the consumer. Producers of cultured milk products, such as yoghurt and cheese, rely on bacteria cultures (starters) to control the product’s acidity, flavour, consistency and aroma. Milk processing units can be broadly categorised into the following types.

Milk Chilling plants: These involve the collection of milk from villages, chilling it to 3-4 degrees and transporting it to the processing unit for further processing and manufacture of dairy products

Market Milk Plants: It involves procurement of milk, pasteurisation, and homogenisation, and lastly, packing it for different brands (standard, toned and double-toned milk) and supplying it to the consumers.

Composite Milk Processing Plants: The project includes the collection of milk and processing into market milk and products like milk powder, cheese, butter, ghee, etc.

Stages in Milk Processing in the Processing Plants

Easy setup of processing plants, procuring and processing milk through hygienic methods is possible today with the technologies developed in the industry. However, the unit will need a Pollution Board certificate for milk processing before starting its operation.

Receiving Raw Milk and its Storage: Once the raw milk arrives at the processing plant, the quality team tests it to ensure it meets applicable standards. Large vertical silo tanks are used to store untreated raw milk.

Pasteurising – The stored milk is heated to a specific temperature to destroy the pathogenic microorganisms. Pasteurisation makes milk safe to drink (and also helps to prolong its shelf-life). It is essential to separate bacteria and other contaminants from the milk to make it fit for consumption.

Separation and clarification: Separating cream from milk is a process that uses centrifugal forces to separate the cream from the skim milk so it can be used in other products. Clarification separates particles such as somatic cells, sediment and some bacteria from the milk.

Standardisation and Homogenising – Standardisation is the process of adjusting milk fat content to a specified value. At the same time, homogenisation of milk is done to make milk consistent by breaking down heavier particles, such as fat globules, into tiny particles.

How to start a milk processing unit

Today, substantial assistance to processing plants to procure and process milk in hygienic methods within a short period is available after obtaining a Pollution Board certificate for milk processing. However, the following requirements must be decided upon beforehand to start a processing unit.

Land: Ample space is required for buildings and machine setup, parking of transport vehicles, empty cans and factoring the scope of future expansion. By a rough estimate, a processing plant on two acres of land can handle about 10000 litres of milk per day.

Suitable Location: The location of the site should have proximity to the source of milk collection points as well as to the road and rail services and other requirements like water, electricity, social infrastructure, etc.

Machinery and utilities: The machinery for the processing plant should be as per the standards specified by law. Many states of art infrastructures are present in the industry that reduces the time for processing. With the correct type of applications, it is easier for the milk processing units to deliver quality products on time. Utilities will include the availability of power, water (steam), fuel, transport vehicles etc.

Staffing: the total requirement of the workforce depends on the operations involved, the quantity of milk handled, and the level of automation. Various technologies are being integrated with the automation process to enhance processing plants. Different automation applications are combined into a single application through modern technologies.
