In our area, where most of the year is negative or close to zero temperature, it is foolish not taken advantage of the free cold storage of vegetables, fruit, roots. It would be nice. for example that the houses were built with the corresponding chambers in the walls of the kitchen, where he was would be Santa Claus. But somehow, the architects of this not yet provide. However, the situation can be corrected by yourself. I have made and for several years successfully operated kitchen wall Cabinet-column for storing potatoes. Through the intake tube, it enters from the street the cold air. Overlapping holes if necessary, you can adjust the temperature in the column.
The Cabinet is made from boards in the thickness of 30 mm, two of them assembled the side and rear walls, lid and bottom. These elements are connected among themselves and with the lower part of the front wall, which is mounted on fortochnyh hinges to horizontal door brace. The side walls of the Cabinet have grooves to move the three sliding up and down of plywood panels with a thickness of 10 mm, forming the front wall. To download tubers panels-valves one by one rise up, dropping into place as the filling compartments.
Located inside (under counter angles) five shelves to spread out the weight of the potatoes and prevent it from being crushed. The slope of the shelves ensures gradual degradation of the tubers as they are spending (the bottom door).
