FRANZ LITTMANN, at VAASS & LITTMANN in HALLE a. S.Apparat "for the production of water for the production of crystals.

Patented in the German Empire on December 4th, 1878.

If ordinary water is used to make ice, the ice made from it becomes white and snow-like due to the air in the water.

The present apparatus is intended to produce the water completely free of air and to cool it down to such an extent that it can be used for ice-making, and in this way crystal-clear ice can be made with ice machines of any system.
The apparatus consists of the following parts:

A steam cleaning cylinder,

B cooking cylinder,

C steam condensation cylinder,

D cooling cylinder,

E Condensation water drainage pot.

The steam cleaning cylinder A consists of the outer cylinder A and an inner U, which is suspended in the former. The entire height of the cylinder U is provided with opposing arched plates. . The downwardly curved plates close close to the edge of the cylinder U and have an opening in the middle to allow the steam to pass through; the upwardly curved full plates cover the opening of the lower plates and protrude from the edge of the cylinder U in order to let the steam through on the side. The cylinder is provided with a cover on which there are two nozzles 1 and 18, from where the steam is passed on. At the bottom of the cylinder A are two nozzles 20 and 21; The steam coming from the steam boiler enters through 20 and by having to go through the plate system U , the water carried along from the steam boiler precipitates and goes through the condensation water drainage pot at 21, while the pure steam can exit at ι and 18.

The interior of the cooking cylinder B has a coiled pipe N, through which the steam from the cylinder A passes and flows to the condensation cylinder C in order to supply the condensed water which flows from the condensation cylinder C through the pipe 5-6 to the cooking cylinder B. Bring to a boil. There is a pressure gauge T on the lid of the cooking cylinder to show the pressure inside; furthermore a passage set 7 from which the air impregnated with steam passes after the cylinder C. On the lower part of the cylinder there are two through-connections with taps P and 5 and, furthermore, in the middle of the cylinder there is a water level indicator R.

The condensation cylinder C has a coiled tube M inside, through which cold water runs in order to condense the steam flowing into the cylinder. On the cover there are three through nozzles 4, 8 and 19. The steam comes out of the coil N through 4, the air laden with steam which develops in the cooking cylinder B through 8, and 19 serves to condensate the water that comes out of the steam heater an ice machine wins, introduce. Furthermore, there is a valve G on the cover, which allows the vapor impregnated with air to flow out. The valve is so constructed that it closes and prevents the inflow of external air in the event that the air void in the cylinder should be distorted. At the same time, the valve is provided with a cock H so that the outflow can be regulated as required.

The cooling cylinder D is an open cylinder in which there is a coiled pipe L , around which the cooling water is passed in order to cool the boiling, air-free water that comes from the cooking cylinder B, from the pipes 9 to 10, through this coiled pipe . The outlet of the coiled pipe is provided with a tap K , by means of which the cooled water is drained off. A rubber hose is attached to this tap and carries the float valve J at the lower end. This float valve is intended to prevent air from entering the water which is drained into cans in order to make it freeze. The valve is so constructed that the water pressure opens it; as soon as it starts running, the valve is closed by a spring. The valve is enclosed in a hermetically sealed can that serves as a float.

The operation of the apparatus is as follows:

The steam coming from the steam boiler enters the steam cleaning cylinder A at the nozzle 20, passes through the plate system. of the cylinder U, where it precipitates the entrained water, which descends into the cy-

linder A runs and is discharged through the condensation water drainage pot. The anhydrous steam goes at ι after the coil of the cooking cylinder B, flows through the coiled pipe N located in this cylinder and from there through the pipe 3-4 to the condensation cylinder C, where it by virtue of the cold water which runs through the coiled pipe M and although it runs in at 13 and expires at 14, condenses. The water condensed in this cylinder falls through pipe 5-6 to the boiling cylinder B, where it is brought to the boil by the steam passing through the coiled pipe N. The air and steam escaping from the boil pass through the pipe 7-8 to the condensation cylinder C, where the steam condenses and the air flows out through the valve G.

The boiled air-free. Water goes from the cooking cylinder B at the tap P located below through the pipe 9-10 to the coiled pipe of the cooling cylinder £>, in which it is cooled by the cold water flowing into the cylinder at 16, which rises up around the coil , and is then let into the ice-cream tubs at tap K through valve J. The heated cooling water runs out of the cylinder D at 17.

7Y

The tap 5 on the cooking cylinder is used to be able to drain the water from the cylinder, the water level pointer R to be able to control the withdrawal of the boiled water. The manometer shows the pressure in the cooking cylinder, which is created by the boiling. F is a vessel filled with water, into which the pipe, coming from the air valve G , opens, and which has a tap H to be able to regulate the outflow of air. The pipe ends below the water level in order to be able to observe the outflow of air, which is indicated by air bubbles on the surface of the water.

Claims (1)

PATENT CLAIM: Those parts of the apparatus which, in contrast to the Wicke's apparatus, do the heating of the condensed water by means of steam supplied in serpentine tubes with avoidance a pump to discharge the heated water and allow the condensation in a hermetically sealed cylinder with a coiled pipe through which cooling water passes.
