Great idea to design a small milk chiller that works on the small biogas system. In most cases it is too cumbersome to get the evening milk from remote farms to the dairy factory. Much better to get it there in the morning together with the morning milk. The chilling enhances the milk quality enormously. Uncooled milk cannot be used properly by the dairy factory and often has to be discarded. I am impressed that you guys managed to get the new type of chiller that is cheap and easy to install and that works on biogas ready to market so soon! Congratulations!
