A HUMIDIFIER FOR LEMON CURING ROOMS. 



Naturally, the higher the raised slot extended above the water, the 

 slower was the passage of water to the lower pan. 



In this work it is desirable to keep the cloths saturated dining the 

 operation of the machine, but with little or no excess of water 

 dripping into the lower pan. As finally constructed, after many 

 tests to determine the best arrangement, it was found that raising 

 the slots 4 inches above the bottom of the pan keeps the cloths fully 

 saturated under the conditions in which this machine is used. An- 

 other method of controlling the flow of water through the cloths 

 is to vary the quantity of water in the upper pan, filling up the pan 

 so that the water nearly reaches the tops of the raised slots in order 

 to increase the rate 

 of the flow or draw- 

 ing off some of the 

 water in order to re- 

 tard its flow. 



If it is desirable 

 to stop the absorp- 

 tion of the water by 

 the cloths at any 

 time, this can be 

 done easily by lift- 

 ing the ends of the 

 cloths out of the 

 water in the upper 

 pan. If the flow of 

 water through the 

 cloths is such as to 

 collect in the lower 

 pan, this excess can 

 be drawn off and re- 

 turned to the upper 

 pan. Under condi- 

 tions of very low humidity, when evaporation from the cloths is very 

 rapid, it may be found advisable to maintain some water in the lower 

 pan, as well as in the upper one, in order to keep the cloths fully 

 saturated. 



The operation of this humidifier washes all of the air in the room 

 and increases the humidity uniformly, a very important factor in 

 lemon curing rooms. Another fact of great importance is that under 

 conditions of low humidity the humidifier acts rapidly, while under 

 conditions of high humidity it works slowly. One advantage of this 

 condition is that it reduces the danger of raising the humidity of the 

 curing room to a point which would be unfavorable for lemon curing. 

 On an average the humidifier will raise the humiditv in the rooms de-
