• running cooling device

It let known to be used for freezing and preserving food and other perishable foods To expose substances to the direct action of a refrigerant, e.g. nitrogen This type of freezing has the advantage that the perishable goods very quickly Chilled to a praiseworthy low temperature vferden. However, it has the disadvantage that considerable amounts of refrigerants are required for cold preservation over long periods of time, This type of freezing and preservation is therefore generally only used for longer periods of time Routes used in deep-freeze vehicles, and in large industrial refrigeration systems industrial freezing of food "

For freezing and Konservleren low-fat pastry on Veizenbasie, for example, there 1st required, the temperature range of + 30 ° C to below - to pass through extremely 7 ⁰ C quickly. This is only possible to an extremely unsatisfactory degree with conventional freezers, which consist of a cooling unit and evaporator, compressor with drive and condenser.

1Q982S / G & 64

The object of the present invention is to provide the known devices for freezing and preserves of easily spoiled Goods, especially foodstuffs, where the coolant acts directly on the goods, designed in such a way that the loss of refrigerants is kept to a minimum. thereby this type of cooling and the necessary equipment for household, trade and commerce are economically viable.

This task is essentially carried out by a deep-freezing device * summed up by freezing and preserving perishable goods, especially food, which consists of two or more Side by side freezer chambers bsv · Freezers with outlets for Refrigerant inside and with connecting pipes from the previous to the next There is a freezer chamber in which the outlet openings to the interior of the first chamber are connected to a Refrigerant tanks are connected.

The relaxing and evaporating refrigerant flowing out of the refrigerant container flows into the harvesting chamber and is removed from it Environment heat and cools the out schookartlg stored in the first chamber. Flows through the connecting pipe from the first to the second chamber the still cold refrigerant in the wide chamber etc. and can be used to preserve the stored goods. In operation that will Well, what goes into sales or processing, taken from the last chamber and that Out is located in the previous chambers. One chamber is moved up in each case. Prish out

only gets into the first chamber where the still fresh refrigerant coming from the refrigerant container flows in. To the first chamber The goods are therefore suddenly withdrawn from inserted goods, and in a very short time they are cooled from the insertion temperature to the temperature required for preservation and frozen.

In an expedient embodiment of the invention, it is it is possible to provide the shut-off element for the refrigerant tank with an actuating device, the one with the temperature in the first chamber sensing thermostat is coupled. With this ^ φ The shut-off element of the refrigerant tank is opened as soon as the temperature is in the first circuit Chamber exceeds a certain Mi nine st value and closed again as soon as the value falls below a set •! indest value. ,

Appropriate embodiments of an inventive Cooling device are shown in the description of the figures and in the sub-claims.
