Description

"ICE CREAM PACKAGE AND METHOD"
This invention relates to the packaging of ice cream and to the method and apparatus for packaging the ice cream in a convenient and attractive manner.
DESCRIPTION OF THE PRIOR ART
Ice cream which is sold- for the domestic use is usually sold in containers, either in block form contained in a cardboard package, or in containers of one of the plastics materials, these containers either being square, round or of bucket form. While these are satisfactory in many respects, for large quantities to be stored, a relatively large freezer unit has to be provided, and when once a package is opened, the ice cream therein is subject to deterioration in structure by crystal growth and by the ice cream becoming harder.
U.S. Patent No. 2,563,278 discloses apparatus and method for forming frozen confections, in which cylindrical bags are formed into which metered quantities of a product of an ice confection in semi-plastic form are fed by a reciprocating piston pump into the bag which is then sealed, the mixture being about 2 F above freezing point.
Australian Patent No. 439,425 is directed to the sterilisation of a web of plastic material which is then formed into a tube to be fed to a—forming and welding apparatus to form tetrahedral packages for the liquid to be packaged.
Australian Patent No. 256,049, similar to 439,425 is also directed to the sterile packaging of sterile products Australian Patent No. 479,097 is concerned with the sterilisation of packaging, the level of the liquid being packaged being float controlled.
Australian Patent Specification No. 54735/73 is directe to the filling of packages with viscous materials, to fill preformed tubes which are placed on a filling head, the invention being directed to the cutting off of the viscous material to avoid drips and consequent fouling of the container with product. This also discloses the relieving of pressure in the filling head, the pressure relieving tubebeing open at all times through a restricted opening.
Products such as meats and sausages and the like are known to be packaged in a tubular package formed of plastic film having gathered ends and secured by metal closures.
Conventionally in such packaging machines the packaging film is fed from a roll over a forming cylinder and is sealed into a continuous tube. The product can then be introduced through the tube by a variable speed positive displacement metering pump which controls the flow of rate of the product. The control of flow and tube formation rates maintains accurate weight and package length.
The film containing the product is propelled by drive wheels to voider wheels which are timed to void the product from the plastic tube. Closure plates then gather the voided tube and install the top closure clip on one package and the lower clip on the following package while simulta¬ neously a knife cuts the plastic tube midway between the two clips whereby the lower package is then complete and slides down an exit chute into a container or take-away conveyor. Such a machine is typified by a KARTRIG PAK CHUB machine, model 43.
PI However for the continuous packaging of ice cream by th method, the ice cream must be fed continuously to the inlet to the positive displacement pump and it is to this feed to which the present invention relates.
BRIEF STATEMENT OF THE INVENTION
It is an object of this invention to provide a feed means to a packaging machine for the packing of ice cream.
It is a further object to provide a packaging of ice cream.
Thus there is provided according to the invention the continuous packaging of ice cream supplied from con¬ tinuously operating churns positively feeding the ice cream to a packaging machine having a positive packaging pump, the ice cream at a temperature below 0 C having high viscosity being fed to the inlet to the packaging machine through an inlet pipe via an angular junction, there being a pressure relief valve connected to the angular junction operating to maintain the desired pressure and flow of ice cream to the packaging machine.
Preferably the junction is a T junction with the flow from the churns being connected to the stem of the T, s that the ice cream must turn to flow to the packaging machine connected to one arm of the T, the relief valve being connected to the other arm."—
The ice cream at this temperature in its highly viscous state acts as a solid as it flows through a pipe, and thus for pressure regulation, the flow must turn to both the inlet to the machine or to the relief valve, for if the connections were otherwise, the ice cream would flow past the respective inlet to the packaging machine or the pressure relief valve. Thus the T junction causes equalisation of pressure in the T junction between the pressure relief valve and the inlet to the packaging machine.
The ice cream is supplied to the packaging machine 1 which is a KARTRIG PAK CHUB machine, model 43, in a continuou process from one or more ice cream churns (not shown) . These churns rely on a positive feed mix into the barrels and a positive ice cream extrusion pump to deliver the ice cream.
Thus for a continuous process the output from the ice cream churn or churns must be coterminus with the feed to the inlet to the pump of the packaging machine.
BRIEF DESCRIPTION OF THE DRAWINGS
In order to more fully describe the invention reference will now be made to the accompanying drawings in which:
FIG. 1 shows a package of ice cream,
FIG. 2 shows the feed from the churn to the packaging machine, and
FIG. 3 shows further detail of the fitting.
DESCRIPTION OF PREFERRED EMBODIMENT
The pipe 1 receives ice cream from the positive pumps of the ice cream churns (not shown) , the ice cream then passing through pipe 2 and a T junction 3 to the inlet 14 of the packaging machine 13. The pipe 2 extends to the T junction 3, the end of the pipe 2 being closed by a fitting 4 having a pressure gauge 5.
To the other arm of the T junction 3 there is provided a pipe 6 leading to a pressure relief valve 7 connected to pipe 8 leading to a waste container.
At the inlet pipe 1 there Is provided a bypass valve 9 being controlled by an air operated bypass mechanism 10. Behind the bypass valve 9 a pipe 11 is connected to the discharge pipe 8.
The air operated bypass valve 9 is actuated during the starting up and closing down of the run, so that during these periods of time the ice cream will pass from pipe 1 through pipe 11 to the discharge pipe 8.
The pressure relief valve 7 is controlled by a control screw 12.
It is to be realised that ice cream delivered from the churns is below freezing, preferably at a temperature of -5 C, and at this temperature while it is in a condition to be pumped as a fluid, in practice as it is passing through the pipes it could be considered to be a solid. Hence for this reason it has been found necessary to place the pressure relief valve 7 at the T junction 3 for it has been found that if the inlet._yalve 7 were situated prior to the T junction 3, and if for some reason there is a pressure build up in the T junction 3 due to either a malfunction or not correct correlation between the rate of feed from the churns to the packaging pump, that the ice cream tends to flow past the pressure relief valve due to it behaving as a solid and thus increasing the pressure in the T junction 3 without it being adequately released. Similarly If the connection to the pressure relief valve were in line with the pipe 2, with an angular junction to the inlet to the packaging machine, the ice cream would tend to flow to the relief valve without passing into the inlet to the packaging machine.
Thus by positioning the relief valve 7 at the T junc¬ tion 3, and opposite to the inlet to the packaging machine, the ice cream must turn and pass into the inlet to the packaging machine as it is stopped by the T junction 3, and to equally turn to the pipe 6 to the relief valve 7.
If an increase in pressure does occur in the T junction 3, or if the feed rate is slightly higher, this pressure is immediately applied to the relief valve 7 without there being an undue increase in pressure in the T junction 3.
Hence the relief valve diverts excess product from between the two positive pressure pumps, one on the churn an the other on the packaging machine.
It has been found for satisfactory packaging of the ice cream that the ice cream be delivered from the churns at a lower temperature than the ice cream packaged in larger containers, the temperature of the present invention ice cream being -5 C while that of the conventional Ice cream is at a temperature of 1 C. Also the speed of the churns is reduced thus giving an ice cream quality suitable for such packaging.
While in the preferred embodiment a T junction is shown, it is to be realised that other angular junctions can be used, as long as the ice cream does not have a straight through passage, but must turn through an angle to the inlet to the package machine and to the pressure relief valve.
OMPI
**N O The general formulation of the ice cream can be varied as desired from that of conventional ice cream, and can have an overrun of 110, compared with the usual overrun of 130.
It is realised of course that overrun is the volume of ice cream obtained in excess of the volume of mix and is usually expressed as "7o overrun". The increased volume is composed mainly of air incorporated during the freezing process and is regulated to give the proper body, texture and palatability necessary to give the desired quality of ice cream.
The film for forming the package to contain the ice cream is a flexible film, and is preferably a laminated film being constructed with at least a single layer of a metalised surface, this being such that the film is relatively tough so that it is not readily punctured or ruptured. The packaging machine forms the film into a tube, the ends of the filled tube 15 being closed by clips 1 in the packaging machine.
The film for the package is fed frdm a roll over a forming cylinder and heat sealed to form a continuous tube. The ice cream is fed into the tube, by a variable speed positive displacement metering pump, the control of the flow and the tube formation rates maintaining the accurate weight and package length. Closure clips are applied and the knife cuts between the two clips, the completed package sliding away.
Although one form of the invention has been described in some detail it is to be realised that the invention is not to be limited thereto but can include various modific tions falling within the spirit and scope of the invention.
