Promethean Spenta Technologies Pvt. Ltd. Ravet, Pune, Maharashtra

The near-quadrupling of milk procurement by dairy cooperatives in Gujarat over the last 15 years — from an average of 45 lakh litres to about 170 lakh litres per day — has been attributed no less to a single factor: 24-hour power in rural areas, including guaranteed three-phase supply for eight hours, enabling village-level societies to install bulk milk coolers (BMC). These, with capacities ranging from 1,000 to 10,000 litres, chill the milk to around 4 degrees celsius at the primary collection point itself, inhibiting microbial growth that can lead to undesirable qualitytaste changes and expedite spoilage.

Promethean Power Systems designs and manufactures refrigeration systems for cold-storage and milk chilling applications in off-grid and partially electrified areas of developing countries. Our goal is to enable village-level chilling with a range of products that deliver high-quality produce to our customers. What excites us the most is that not only is this a great market need but also a win-win-win opportunity: a way to make a positive impact on quality and costs with dairy processors, better quality products for consumers, and increased opportunities for farmers in villages across India.

Promethean’s Conventional Milk Chiller is a modular milk chilling system that can cool from 35o to 4o C without a diesel generator.   The capacity of the system ranges from 500 Litres/Day to 2000 Litres/Day. It works even if there is no power during the milk collection by using only 4 hours of intermittent grid power between each milking shift. The Conventional Milk Chiller is a solution for customers who are sensitive to the chilling costs and would like to reduce their operational expenses by replacing the high cost diesel with lower cost thermal energy.

A modular milk chilling system that can cool from 35o to 4o C without a diesel generator. The system cools in 2 stages. First the milk is poured on the Rapid Milk Chiller which instantaneously chills the milk to 8o C with a flow rate of 350 litreshour. The chilled milk is then stores in the SS tank which cools the milk gradually to 4o C. The capacity of the system is 1000 litresday and it works even if there is no power during the milk collection by using only 4 hours of intermittent grid power between each milking shift. The Rapid Milk Chiller Premium is an ideal solution for customers who are looking to collect the highest quality of milk. The combination of Rapid Chiller with the SS tank helps in both cooling the milk instantaneously as well as maintaining the low temperature. By eliminating DG set, Promethean Milk Chiller provides the most cost effective way of collecting top quality chilled milk from village milk collection centers where grid power is erratic.

The system can chill 1000 litres of milk per day, even if there is no power during the milk collection by using only 4 hours of intermittent grid power between each milking shift. The Rapid Milk Chiller is ideal in situations where there is a long gap between the milking by the farmers and the milk reaching the collection centre.

Promethean’s Cold Storage Solutions (CSS) is the most economical way to chill, store and transport fresh fruits, vegetables and other perishables. Chilling the fresh produce immediately at the source is the most optimal solution to India’s cold-storage challenge. This stationary cooling system can chill farm produce under erratic grid conditions without requiring a diesel generator. At the heart of the CSS is Promethean’s Thermal Storage System that can store and release large amounts of thermal energy and can be applied to various cooling applications.
