Integrated Thermoelectric Cooler

Thermoelectric cooling is created by running electricity through two adjacent materials. The PE effect occurs as heat is transferred to one side of the device, effectively cooling the other side. By applying more power, more cooling is created on one side of the device and additional heat on the other, which may be dissipated or utilized for heating.

The major advantages of the thermoelectric cooler versus conventional refrigerant systems include greater mechanical simplicity with no moving parts or liquids, a smaller footprint and less maintenance. Ideal for climate control applications in compact spaces to maintain a consistent temperature, thermoelectric coolers provide effective, reliable operation in demanding environments.

  • Broad operating temperature range of -40 to 55° C (-40 to 131° F)
  • DC powered operation for 12 V applications
  • Refrigerant-free; requires no compressor
  • Cooling capacity 60 W (204 BTUs/Hr)
  • Filterless design reduces maintenance requirements
  • Retains temperature for 8 hours with full battery charge.

The challenge

Standards of Quality and Safety

Out of the 300,000 milk villages producing milk in India, only 120,000 are able to produce milk for the organized industry because they cannot achieve the standards of quality and safety.

Collection of Milk

Dairy processors cannot collect the milk from more than half of the producers because they must collect and transport the product quickly since bacteria spoils it in 4 hours if it is not refrigerated.

Milk Transportation

Milk transportation costs are very expensive in India because producers have to collect the milk from millions of individual farmers who produce between five and ten liters of milk which must be quickly transported twice a day to prevent the milk from spoiling.

The Solution

Cooling Milk at Source

  • It enables dairy processors to collect milk from the rural producers that were outside the supply chain and as a result produce more while saving costs since milk can wait longer to be collected.
  • Producers earn three times the income because of the increasing quality of their products.
  • India’s growing middle class, demanding better quality products, can gain access to healthier milk.
  • The system can slow down the fresh food waste in India.

However, in this marketplace, problems such as the hot climate, the large distances and dispersion of milk producers, and especially the lack of access to electricity, hinder access to quality milk for consumers and cause the waste of large amounts of fresh food and make it difficult for the dairy industry to allow a safe supply chain.
