A Successful Cold Storage for Apples.
H. F. HANSEN, ORCHARDIST, ALBERT LEA.
Mr. Clarence Wedge: I want to preface this short paper with the statement that Mr. Hansen is a man who has worked himself up from the very bottom of the horticultural ladder. He came to Albert Lea a very poor man, and I think supported himself for some time by trapping and fishing and such work as he was able to do. He is a man with a great tendency to investigate and to work out problems for himself. By his thrift and persevering investigations he has brought himself into a fine property and great success. He is the market gardener in our part of the country and a credit to his kind. (Mr. Wedge reads the paper.)
When my orchard, near the city of Albert Lea, began to bear heavy crops of fruit, I found it very desirable to hold the Wealthy and other kinds that ripen at the same time until after the farmers had marketed their fruit. We have a very good cold storage in Albert Lea that is open to the public, but the price they charge is sixty cents per barrel for two months' storage, which is more than the fruit will bear, and so I began to think of putting up a cold storage of my own.
My first one was built underground with pipes for ice and salt to cool it, something like the system that I am now using. But I found out in the first season that it takes a great deal of ice to offset the heat that is coming in from the ground at the sides and bottom of the cellar. And so I built the storage which I am now using entirely above ground, using the basement under it for storing cabbage and vegetables. I built this in 1913, the size 28x56 feet, using cement blocks for the basement, where the cabbages are stored. The cold storage above this is built as follows:
First, an ordinary frame building with 2x4 inch studdings sheathed on the outside with drop siding with No. 3 flooring. Inside of this sheathing 2x4 inch studs placed flatwise, sheathed on the inside with No. 3 flooring, and the six-inch space back of the studs filled with sawdust. On the outside of this firing strips one-half foot are nailed, which are covered with linofelt. One-half foot firing strips are nailed inside of this, and these also covered with linofelt. To this again one-half foot firing strips are added, to which are nailed metal lath, and the whole is plastered with cement. The floor both above and below is made of 2×12 joists, with No. 3 flooring nailed below the joints, the space between which is then filled with ten inches of saw dust, leaving an air space of two inches at the upper edge of the joists. The joists are then covered with linofelt and then the linofelt covered with No. 3 flooring.
On the north and west sides I found it necessary to add one more waterproof coat of linofelt in order to make sure of keeping out the frost.
I have so far only finished up for cold storage one-half of the room, using the other half for a packing room, so that my present facilities are only 28×28 feet. This room is cooled by eight inch pipes of galvanized iron, extending from the attic above to troughs near the floor, that are sloping so as to carry off the melted ice. These pipes are on both sides about two feet apart. The ice is pulled up into the attic by horsepower and broken up small enough into pieces to feed the pipes. The amount of salt used with the ice depends upon how fast we want the ice to melt. A large quantity of salt cools the storage down quicker. In practice I find that it takes one hour for a man to elevate a ton of ice, chop it up and fill the pipes. They hold something over a ton and must be filled every other day in ordinary September weather. It will not do to let the pipes remain less than one-half full. When the ice gets down that far, we have to fill again.
The total cost of my storage when it is entirely furnished up and the present capacity doubled will be about $3,000.00. At present it holds 2,000 standard size apple boxes.
I find that it only pays to put in good fruit that in ordinary seasons will keep until the first of March and hold its flavor well and give good satisfaction on the market. Icing stops about the middle of November. The cost per box for storage is as follows: Ice and salt, ten cents. Interest on investment, six cents. I have figured out carefully the entire cost of growing and storing apples, and find out that leaving out the interest on the value of the land, it will approximate forty-eight cents per bushel. This includes cultivation, spraying, packing, and picking. The question which now interests me is whether we can grow fruit good enough and stand the expense and compete with apples grown in the other good fruit sections of the country.
Mr. Older: I had the pleasure of visiting this plant with Mr. Wedge, and this man had quite a good many boxes of as fine apples as you would wish to see. This was along the latter part of February, and they were in fine condition. He had a lot of Jonathans and Yankees and some other varieties I don't remember, grown on top-worked trees there.
