Abstract

The present invention relates to a storage device for fresh products and/or perishable produce and a method for storing fresh products, comprising: a cabinet provided with an access door and/or flap; one or more substantially gastight compartments arranged in the cabinet and provided with at least one gas inlet and one gas outlet; and conditioning means suitable for conditioning the climate in the compartment, wherein the conditioning comprises of providing desired gas conditions, including oxygen content.

Claims

1. A storage device for fresh products and/or perishable produce, comprising:

a cabinet provided with an access door and/or flap;

at least two substantially gastight compartments arranged in the cabinet and wherein each is provided with at least one gas inlet and one gas outlet;

a gas supply conduit for supplying gas to the compartments, and

conditioning means suitable for conditioning the climate in the compartment, wherein the conditioning comprises of providing desired gas conditions, including oxygen content, wherein the conditioning means comprises;

a) an outlet of a compartment operatively connected to an inlet of another compartment such that the compartments are connected in series, wherein the inlet of a first compartment is connected to the gas supply conduit such that a switch block is able to configure the flow from the outlet of one compartment to the inlet of another compartment;

b) a bypass flow conduit extending from the gas supply conduit and, together with the gas conduit, is connected to the compartments in parallel such that the switch block is able to configure the flow to travel directly to an inlet of any one or more compartments; and

c) a drain conduit extending from drains of each compartment and connected in parallel to an exit flow conduit such that the switch block is able to configure the flow from any one or more compartments directly to the exit flow conduit; and

wherein each compartment can be individually conditioned through the switch block.

2. The storage device as claimed in claim 1, wherein compartments are provided with individual adjusting means.

3. The storage device as claimed in claim 2, comprising a conditioning controller for adapting the conditions in compartments to each other.

4. The storage device as claimed in claim 1, further comprising a gas generator.

5. The storage device as claimed in claim 4, wherein the gas generator comprises a nitrogen membrane.

6. The storage device as claimed in claim 1, wherein the cabinet is adapted so that it can be placed as build-in appliance in a kitchen.

7. The storage device as claimed in claim 1, comprising an external draining connection for drawing off conditioned gas.

8. The storage device as claimed in claim 1, comprising a filling opening for the supply of gas conditioning products or compositions.

9. The storage device as claimed in claim 8, wherein the filling opening comprises a tablet storage space.

10. The storage device as claimed in claim 1, further comprising at least two connectors for operatively connecting the at least two compartments to conditioning equipment placed outside the storage device.

11. The storage device as claimed in claim 10, further comprising displacing means for displacing the storage device such that an operative connection can be realized via connectors.

12. The storage device as claimed in claim 1, wherein the at least two compartments are displaceable independently of the cabinet and embodied such that a compartment can be placed in and removed from the cabinet.

13. A storage container suitable for application in combination with a storage device as claimed in claim 1.

14. A tablet suitable for application in a storage device as claimed in claim 1.

15. The tablet as claimed in claim 14, suitable for producing carbon dioxide.

16. The tablet as claimed in claim 14, suitable for producing ethylene.

17. A method for storing fresh products using the storage device as claimed in claim 1, comprising the steps of:

placing the products in a storage device as claimed in claim 1;

selecting the desired conditions for the products;

storing the products in the storage device; and

connecting an outlet of a first compartment to the inlet of a second compartment.

18. The method as claimed in claim 17, wherein the storage of the products comprises ripening the products.

19. The method as claimed in claim 18, wherein the step of connecting an outlet of a first compartment to the inlet of a second compartment is for the purpose of using gases produced by products in the first compartment for ripening products in the second compartment.

20. The method as claimed in claim 17, wherein the storage of the products comprises displacing and subsequently connecting the storage device to a centrally positioned conditioning system.

21. The storage device as claimed in claim 1, wherein groups of fresh products can be stored at the desired conditions associated with these products and further including a conditioning controller to adapt these conditions to each other in order to realize an effective and efficient storage.
