It has been imagined that sun and wind alone dry clothes but the fact is that air is the drying medium and therefore the best dryers provide a good circulation of air plus heat. Dry air has a tremendous love for moisture and eats it up as a blotter eats up ink. The warmer the air the more moisture it will hug. This would seem enough, just to bake the clothes, but baking does not remove odors and does render them yellow; they are unventilated and smell like the laundry, so people are prone to say “Sun drying or nothing.” However, the best dryers provide for circulation of air. At its best the air changes from 250 to 300 times an hour. The air must change, for after one lot of air holds all the moisture it can, it cannot take any more from the clothes, and new arid air must be substituted for that which is moisture-fed. This is accomplished by a moist air exhaust in the newer dryers, which are larger than the older types. The result is white, odorless, air-swept clothing. The stream of air is usually accomplished by the use of ordinary chimney draft assisted by the warm products of heating from the heater. The hot air products of combustion pass through a tapered nozzle into the moist air exhaust pipe, and by the speed a suction is created which helps to pull the moist air out of the cabinet and up the chimney. When you buy a dryer see to it that the exhaust pipe is large so that you will have wind and heat instead of just heat. Air circulation is what you are really buying. See that you get it. SUPERFICIAL POINTS All parts upon which clothes hang should be non-rusting. The racks must pull out without any expenditure of strength and must run quietly. Racks must be within the reach of the average sized woman, to avoid stretching. The heating burner must be simple and easily reached so that you can tell at a glance how much heat you have turned on. There must be ample screening so that should a garment fall it cannot possibly get scorched. The finish of these dryers must be smooth, without protuberances which could in any case tear the garments to be dried. Dryers are best heated with gas, electricity or kerosene. Care must be given to get the best kerosene burner as they are troublesome when not perfection. Dryers are simple to operate, and you are saved: (1) tugging clothes to roof or yard; (2) putting up a wash-line; (3) fastening clothes and tearing them with clothes-pins; (4) carrying heavy baskets anywhere; (5) sprinkling and rolling clothes, because you keep them drying only long enough to be ready to iron; (6) the wear and tear from the exposure to dust, sunburn, fading, snow and other outdoor contaminations. ELECTRICITY OR NONE A very good little dryer, simple as a broiler, is the over-head slatted dryer, which, on a pulley, is spread with clothes and pulled up to the ceiling where the clothes dry by the risen heat of the room.
