APPARATUS FOR COOLING MOLTEN 0R EMULSION-LIKE SUBSTANCES ON A COOLING- SURFACE.

Specification of Letters Patent.

Patented Mar. 2, 1915..

Application filed Februaryv 8, 1913. Serial No. 747,176.

To all whom it may concern:

Be it known that I, CHRrs'rnN CHRISTEM SEN, subject of the King of Denmark, residing at (Oster Farimagsgade 73, Copenhagen, Denmark, have invented new and useful Improvements in Apparatuses for Cooling Molten or Emulsion-Like Substances on a Cooling-Surface, of which the following is a specification.

The present invention refers to an apparatus for spreading and smoothing molten or emulsion-like substances, such as cocoafat and margarin respectively as a coating of desired thickness. on a cooling surface. Several types of such apparatus are known and the essential feature of the new apparatus is the provision of two mutually independent members, adjustable relatively to one another and to the cooling surface, one of the said'members serving to apply the substance while the other one, being held at a certain distance from the cooling surface, serves to determine the thickness of the coating and to smooth this coating on the cooling surface. One or both of said two members may, if desired, be heated by suitable means.

The cooling surface may be shaped as a cylinder, a truncated cone, a circular ring or a plane table, and it may either be movable relatively to the stationary coating and smoothing members, or it may be at rest, while these 'are moving.

A manner of execution with rotary cylindrical cooling surface is represented on the drawing.

Figure 1 showing the apparatus, viewed in the direction of the axis of the cooling surface, partly in section, while Fig. 2 shows the apparatus in plan also partly in section.

The cooling surface K is shaped asa hollow cylinder, rotating about a hollow shaft.

through which the cooling medium, for instance a freezing mixture, is introduced into and discharged from the cavity of the cylinder. The member serving to spread the molten substance consists of a hollow body or sprinkler T, having on the side facing the cooling surface a series of openings a, arranged sloping in relation to a spreading surface S provided below. The tubular wall of the sprinkler is considerably thicker where the openings a are located, so that the latter form narrow channels, and the size and shape of the openings may be varled, according to what is most suitable for the substances to be treated in the apparatus. By having the openings a slantlng toward the spreading surface S, the molten material, pressed out as small 'ets from the openings a, is caused to hit t e spreading surface in such a manner that it is splashed up against the cooling surface as a thin coating and adheres thereto. The spreading surface may be .in fixed connection with the supply tube T, or it may be separated therefrom so that it may be adjusted at different angles or may be removed entirely, all according to what best suits the molten substance in question.

The regulator R, serving to determine the thickness of the coating and to smooth it on the cooling surface, is placed above the spreading surface S and is carried by two arms A which may be turned alongv the cooling surface and may be maintained at any desired level, for instance by means of arms 0, as shown on the drawing.

The clearance between the cooling surface and the curved side of the regulator R, facing the cooling surface, determine the thickness of the coating, and a downwardly directed sharp edge 7 on the regulator R serves to remove any surplus of substance deposited on the cooling surface. The regulator' R may suitably be arranged as a hollow body, as it may then be kept heated by the introduction into its cavity of a heat transmitting medium, whereby any surplus of substance removed from the cooling surface by the said member will melt and drip down on the spreading surface from where it will again be deposited at some other point of the cooling surface.

In order to insure the substance removed being actually conveyed down to the spreading surface the regulator R may suitably be fitted with a downwardly directed flange g, as shown on the drawing. The regulator R may be made adjustable in many manners relatively to the spreading surface S and the cooling surface, so that not only its distance above the spreading surface may be varied by adjustment of the arm 0, but also the distance of the regulator R from. the cooling surface, and the angle between the tangent of the cooling surface and the said drops, it will be smoothed on the cooling surface by passing the heated regulators The layer deposited and cooled --on the cooling surface is successively removed therefrom in known manner by means of a knife k, located at such a point that the layer may remain for a suitable time on the cooling surface.

If it is found desirable to keep the sprinkler T in a heated condition similar means as mentioned in connection with regulator B may be used for this purpose.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim 1s In an apparatus for cooling warm fluid matter such as molten substances or heated fatty emulsions, the combination with a cooling surface of a hollow sprinkler adapted to be adjusted relatively to same and having at its side, facing the cooling surface, fine discharge apertures directed toward the cooling surface and serving to spread the substance onto the same, and a hollow regulator adapted to be adjusted circumferen t-ially as Well as radially to said sprinkler and said cooling surface and to be heated by means of a heat transmitting fluid being passed through its cavityand serving to remove any surplus of the substance deposited. p

The foregoing specification signed at Copenhagen, this 21st day of J anuary. 1913.
