Ice for Commercial Purposes
ICE for commercial purposes is obtained in two ways: either by cuttingduring the winter time from our lakes and rivers and storing in largeIce Storage Houses located alongside, or by freezing pure clean waterby means of artificial refrigeration.
All authorities are agreed that artificial ice is more sanitary thannatural ice and it is only a matter of time when the use of natural icewill be prohibited except in special cases when the purity of itssource of supply is beyond doubt.
Our improved method of making artificial ice will cut the labor costdown to the minimum and will enable the manufacturer to profitably sellartificial ice at the price natural ice can be harvested. The logicalresult thereof will be the building of a large number of modern iceplants all over the country to supply the market with artificial ice inplace of the present natural ice.
We do not claim any wonders for our system but believe that thefollowing points of advantage will convince any practical icemanufacturer that the labor cost has been cut in two.
Second. Our air supply is permanently connected to the cans and the supply to each can can be regulated, if required.
Third. We have a continuous air supply to the cans during freezing aswell as during thawing, dumping and filling. Our air supply neverceases.
Fourth. Our air is automatically cooled down to the temperature of thebrine in the tank thereby eliminating all possibility of moisture inthe air pipes.
Fifth. Our cans are held in a solid frame of steel work and areconnected to the crane from the time the cans are pulled until they areput back into the tanks, thereby doubling the life of the cans.
We give herewith data covering the cost of manufacturing ice and willguarantee that under reasonably fair management the number of menrequired will not be exceeded.
Do not fail to carefully analyze the following cost data. They may seemextremely low but a thorough study of our system will prove them to bevery conservative.
