Developed in New Zealand, the 900W 240v Drum Blanket wraps around a 200 litre plastic or metal drum. A stretch-cord lace allows for easy placement and removal. This device will heat 200 litres of milk or colostrum from 15°C to 28°C in 4 hours. The blanket is thermostatically controlled, so will not over-heat the milk. Power demand is quite low at 900W, so should not cause issues in poorly serviced buildings. Using this blanket there are no cleaning issues and should not be coagulation of milk, as long as it is stirred well from time to time (stirring regularly will reduce heating time.) If the blanket is left on longer than required, the milk should not get hotter than 40°C, due to the safety thermostat in the blanket. Keeping the drum indoors, in a warm still atmosphere whilst heating, will reduce heating time and power usage.
