CELLAR, ON THE BALCONY: THERE IS AN OPTIONLong-term storage of fresh vegetables and fruits — the whole problem, especially in urban environments. Having carefully studied the publications of minigranules (“M-K” No. 2, 1984, “M-K” № 8, 9 and 11 in 1985), I should note that all these structures have a rather complex system of thermoregulation and also made of materials that are very rarely available for sale. Offer your version of the “cellar” on the balcony. For its production need is simple, available and cheap materials: pallet boards with a thickness of 10-15 mm, packaging cardboard, sawdust, asbestos cement sheet or slate.
Wall storage dual, composing shields, between which are placed two sheets of thick cardboard, and the remaining space is filled with sawdust. Under the bottom made from a sheet of slate, poured sawdust also. At the height of 30…50 mm from the bottom is placed the lattice strips 25Х50 mm. In the Assembly of the walls of the joints for tightness, it is desirable to isolate not thick foam.
As shown by operating experience, the presence of dense cover is not absolutely necessary, since moisture contained in vegetables and fruits, during storage is allocated in the form of vapor and condenseries on the cover. Condensate, in turn, drops again, falls to the contents of the vault — there is a kind of “water cycle”, and it is highly desirable. So I put flush-mounted grille, and served it on top of a quilted quilt, made from old jackets. Simple, comfortable and warm!

Fig. 1. Vault (cover-“blanket” is not shown):
1 — grille upper, 2 — lower grille, 3 — heater (electric heater 60 W, 220 V), 4 — beam frame 40x60mm, 5, 9 — chips, 6 — cardboard, 7 — batten sheathing, 8 — bottom plate (slate).
A few words about the heater. They is widespread in everyday life electric heater capacity of 60 W and a voltage of 220 V. the Main advantage is that it gives off heat to a soft, moderately, not as powerful heaters from electric fireplaces or electric lamps, the use of which leads to local overheating of the vegetables (this is proven). A built-in temperature sensor and the possibility of a two-stage heat adjustment modes allow you to maintain the desired temperature for a long time.
To obtain the optimal temperature in the mini-storage heating the need to modify a little bit to readjust the temperature sensor. To do this, carefully open the cover, remove and disconnect the thermostat. Then assemble the wiring diagram (see Fig. 2). Slightly Unscrew the adjustment screw (but not completely) and put the thermostat together with a control thermometer in miranae space that allows a little lifting of the outer frame and observe the thermometer, to make temperature +1…+4°C. When the desired temperature set, you need to start slowly screwing the adjusting screw to the ignition warning lamp. This position of the screw and will work.

1 — the test lamp 60 W, 220 V, 2 — temperature sensor.

After adjusting the sensor using wires of length 15…20 cm is connected to the heater. It is out of the heater is necessary for more accurate temperature maintenance. It remains to tidy up the case, and a modernized version of the heating pads ready to be installed in the vault.
In those regions of the country where there are harsh winters, you can install multiple heaters. The same can be done by increasing storage capacity.
Potatoes and apples recommend to store in small boxes — this gives you the opportunity to periodically check their condition.
