Q642. What role do Bulk Milk Coolers (BMCs) play in the cooperative dairy network of Rajasthan?
Explanation
Bulk Milk Coolers are essential components of the modern dairy supply chain in Rajasthan. They are installed at village collection centers to immediately chill raw milk after procurement. By lowering the temperature, BMCs inhibit the growth of bacteria and maintain the quality of the milk until it can be transported to a larger processing plant. This has significantly reduced milk spoilage and quality.
