Description

Cooling tray
Scope of the invention
The present invention relates to a cooling tray, i.e. a serving tray with a cooling means on which cold foodstuffs are meant to be placed in order to maintain a low temperature when exposed on a salad buffet, other buffet or similar in a room which holds room temperature, or outside. The invention comprises of for example an aluminium sheet or other thermally transmitting metal in which a base insulation is mounted and in which one or more tightly sealed containers with a cooling agent are mounted which after the freezing of the whole tray will constitute the cooling means of the tray.
Background of the invention
Within the present technical field there exist a variety of solutions for keeping foodstuffs cold during serving. Examples of this are e.g. GB 481,244, US, A 5, 478, 988, DE 2925 499 Al and DE 100 63 891 Al. It is desirable to keep the foodstuffs below a temperature of + 80C. This is the highest temperature permitted by the Swedish National Food Administration for chilled foodstuffs served e.g. in a buffet. Authorities regularly control that restaurants and canteens fulfil these regulations. The reason for these regulations is the fact that the growth of bacteria quickly increase at higher temperatures and leave the food unfit for consumption. A too high temperature of chilled food can cause stomach diseases. Besides, chilled food which is kept cold, i.e. below + 80C, taste better. Without any cooling in or on the table, the chilled food cannot be kept at the relevant temperature for more than 20 to 30 minutes. The chill can be added the chilled food through for example the use of a cooling table, in which the chill is added to the table from an electrical cooling device. When the chilled food is put on the cooling table, it absorbs the extra chill from the cold table. These tables are often big and expensive and not flexible.
Other solutions include the use of loose ice or cooling trays. The cooling trays are in a variety of ways provided with some kind of container with a cooling agent, which is frozen to ice in a freezer. Some cooling trays consist of several loose parts, such as a framing in which frozen ice packs, which contain a cooling agent, are placed. On top a lid is mounted. These ice packs contain a cooling agent containing salt, which provide a low melting point providing a lower temperature in the ice pack although this lesser temperature only lasts a relatively short period of time. A disadvantage with a frozen cooling tray with a temperature below 0 0C is that you risk getting frost damages on the chilled food that has been placed on the cooling tray.
When carrying out experiments it has proven difficult to keep cooling trays with these ice packs at the ideal 0 0C under a longer period of time.
Cooling trays containing bags of cooling agent has proven the ability to keep 0 0C for several hours. However, a disadvantage with these cooling trays has appeared. After the use of a frozen cooling tray, an ice residue can sometimes be left in the bags if the cooling tray not has been used long enough. The cooling agent move around in the bags when the temperature is above 0 0C and the cooling agent not is entirely defrosted. If the tray is frozen again in this condition, the bags can burst due to the liquid being underneath the ice residue expanding but being unable to lift the ice and give room to the space needed when the liquid underneath the ice residue freeze to ice and expand. Instead, the liquid expands through the bag or the bags and they will brake at the edges, where they are attached to one another with a scotch tape. Leakage will occur and the cooling tray will be out of order. Since the bags lay flat in the insulation of the cooling tray, the risk of leakage during freezing is greatest when the cooling tray is standing up in the freezer.
In order to avoid this inconvenience when freezing the cooling trays, the cooling trays must be placed horizontally. If you follow the manual, the cooling trays works fine but in large scale kitchens and restaurants with temporary workers being unaware of this, the cooling trays are sometimes placed to fit among the other frozen food in the freezer and this problem occurs.
Summary of the invention
The present invention solves these problems with cooling trays and provides a cooling tray in one piece, inside which the cooling meanss are enclosed and which, after freezing, keep the temperature at 0 0C for many hours in room temperature and which after use can be placed and stacked in its entirety in any possible way in a freezer without risking any leakage.
In accordance with the inventive idea the above mentioned problem is solved by the mentioned cooling agent consisting of water and that the mentioned containers also contain a liquid absorbing material that binds the water in the container or containers and that there is negative pressure in the container or containers.
In accordance with the inventive idea the above mentioned problem is solved by the container or containers consisting of one or several bags made of a foil made of aluminium, plastic or similar, the bags containing a liquid absorbing material that bind the water so that it cannot flow freely in the bag or the bags, and the air being squeezed out of the bags before they are sealed with for example glue.
In accordance with the invention the water is kept in the water absorbing material also when the bag or bags are not frozen. The expansion of the water when freezing to ice will take place in the water absorbing material and the risks of leakage when freezing are eliminated.
In accordance with the inventive idea a cooling tray is provided which after freezing gives a long and even cooling effect at the correct temperature, i.e. 0 0C - +8 0C at a room temperature of +24 0C and hence does not cause frost damages on the food/foodstuffs placed upon it. A cooling tray according to the invention is reliable, it keeps an even temperature, it is easy to handle, it can be placed in any position when freezing in a freezer and it is easy to clean.

Figure 2 shows the detailed parts of the cooling tray shown in figure 1 before assembly and sealing. Figure 3 shows two curves A and B in a diagram over time and temperature of chilled food with a temperature of +3.5 0C. The curve A shows the temperature of the food when placed on a table. The curve B shows the temperature of the same food when placed on a cooling tray in accordance with the invention that has been frozen to -30 °C. The surrounding temperature was +24 0C.

Figure 5 shows a freezer bag according to the invention in cross section with a core of liquid absorbing material filled with water.
Detailed description of the invention
In figures 1 and 2 the main parts of a cooling tray according to the invention are shown. As shown in figure 1 the cooling tray 1 comprises a housing consisting of two parts 2,5, a top part 2 and a bottom part 5, both consisting of a lmm anodized aluminium sheet. On the outer surface of the bottom part 5 there are four rubber pads 6 with a diameter of approx. 30 mm and a height of 3 mm mounted in the corners, and on its inner surface an insulation 4 is mounted which has cavities in which containers of cooling agent 3 for example cooling agent bags 9 are attached with scotch tape. The cooling agent bags 9 made of aluminium foil or plastic foil glued at the edges 8, are filled up with a core 7 of spongy and soft liquid absorbing material as e.g. foamed plastic whereupon the cooling agent 10 in the form of water is filled up and is absorbed by the core 7. The top part 2, formed as a lid, is situated adjacent over the cooling agent bags 9 and the lid is permanently attached to the bottom plate 5 through gluing, welding or similarly in order to create a uniform, closed cooling tray 1 that enclose the cooling agent bags 9 and which is insulated from the underlying surface and at the same time as the cooling tray 1 after freezing, cools the top surface of the lid 2 on which the cold food is placed. The bags 9 can for example be 130 x 150 mm and contain approx 110 ml cooling agent.
When manufacturing the cooling bags 9, the air is pressed out of the bags and the core 7, whereby a negative pressure arises which can take up the expansion created when the cooling agent , the water, is frozen to ice as the cooling tray is placed in a freezer.
In figure 3 two curves, A and B, are shown in a diagram over time and temperature of a chilled food taken from a fridge with a temperature of +3.5 0C. The curve A shows the temperature of the food placed on a cooling tray according to the present invention which has been frozen at -300C. The surrounding temperature was +24 0C.
The diagram clearly shows that the cooling tray quickly within 45 minutes reaches a temperature of 0 0C but that it stays at that temperature for many hours before the temperature slowly rises. New cold dishes can be placed on this cooling tray but after a few hours you have to return the cooling tray to the freezer where several cooling trays can be stacked on top of each other or be placed vertically in rows in order to, after approx 4 hours in -20 0C to -30 0C be ready to use again.
It is of importance to restaurants and cafeterias to keep chilled food on for example a buffet cold as the law states that the temperature of chilled food stuffs must not be above +8 0C. Besides, the authorities regularly control that restaurants and cafeterias live up to the demands and follow the regulations.
With the help of the invention and an insulated box, you can keep chilled food cold during more than a day without electricity and at the same time being mobile, which is appropriate when catering for receptions etc when extra cold space is needed.
The cooling trays can be manufactured in all sizes depending on need and can be used for various purposes where a low temperature is needed for a limited time. Further a transparent lid can be placed over the cooling tray with the food. The lid is lifted when someone is to take food from the cooling tray. In this way the food is protected and can be kept on the cooling tray at a temperature below +8 0C for further many hours.
It should be stressed that the invention naturally can be modified in various ways within the scope of the claims.
