Artificial Permafrost and the Application to the Low Temperature Storage for Foodstuffs
Abstract
In the cold regions like Hokkaido and Tohoku Districts, they have been advocating snow-overcoming, advantages of snow and effective utilization of cold climate. In fact, they have been positively trying to make use of snow and coldness as water resources, energy sources, structural materials and so on.
One of energy utilization is for low temperature storage of foods. Since the potatoes have properties of adapting themselves to cold temperature when they are stored under cold environment, they have the tendency of growing in their sugar contents. As the results, all those foods which are stored under these cold environments will be the products of higher additional value. Here we will introduce the present situation of low temperature storage of foods by artificial permafrost, not only as the construction materials for cold storage house itself but also utilizing its own cold temperature.- Publication:
