Abstract

The invention relates to a yeast cream-dosing device and method. According to the invention, the yeast cream is disposed in an interchangeable transport container ( 20 ) which is located inside a refrigerating compartment ( 10 ), the aforementioned container being connected to an extraction opening ( 27 ) by means of an outlet conduit ( 26 ) which can be opened and closed by an opening/closing mechanism ( 30 ).

First claim

The invention claimed is:

1. A device for dosing of stable bakers' yeast cream in a bakery, said device comprising:
a piece of furniture provided with a refrigerated compartment having an internal temperature regulated at between −2° C. and 12° C.;
an indicator showing the temperature inside said refrigerated compartment;
an alarm alerting when the temperature inside the refrigerated compartment does not correspond to a determined temperature range;
an interchangeable transport reservoir located in the refrigerated compartment and containing stable yeast cream, said reservoir having a total internal volume of between 1 and 100 liters, and an outlet opening for the yeast cream;
an outlet conduit for dosing of the yeast cream, said conduit connecting the outlet opening of the interchangeable transport reservoir to a dispensing opening outside the refrigerated chamber; and
an opening/closing mechanism for the outlet conduit, enabling the opening of the outlet conduit for the dispensing of the yeast cream and enabling the closure of the outlet conduit in order to stop the dispensing of the yeast cream,
said device permitting the dispensing of a dosed quantity of yeast cream from the interchangeable transport reservoir via the dispensing opening, and
said device being devoid of any agitator for mixing the content of the transport reservoir
wherein said interchangeable transport reservoir is a collapsible bag that permits the dispensing of a dosed quantity of yeast cream via the dispensing opening by activation of the opening/closing mechanism without entry of gas from outside the collapsible bag into the collapsible bag.

2. The device according to claim 1 , wherein said collapsible bag is surrounded by one or more outer packagings.

3. The device according to claim 2 , wherein said collapsible bag is surrounded by one or more outer packagings selected from protective outer packagings made of a flexible material, a wire basket or a self-supporting casing.

4. The device according to claim 1 , wherein said outlet conduit is a tube with open ends.

5. The device according to claim 1 , wherein said outlet conduit comprises a flexible part and said opening/closing mechanism enables the closing of said outlet conduit by pinching said flexible part and the opening of the outlet conduit by releasing said flexible part.

6. The device according to claim 1 , further comprising a weighing apparatus provided with a support surface for a receptacle, said weighing apparatus enabling the weighing of the quantity of the yeast cream introduced into the receptacle via said dispensing opening during dispensing of the yeast cream.

7. The device according to claim 1 , further comprising a control station activating the opening and closure of said outlet conduit by said opening/closing mechanism.

8. The device according to claim 7 , wherein said control station activates the closure of said outlet conduit once a desired quantity of the yeast cream is present in a receptacle.

9. The device according to claim 1 , wherein said piece of furniture comprises at least two refrigerated compartments which contain an interchangeable transport reservoir containing stable yeast cream and having a total internal-volume of between 1 and 100 liters and an outlet opening for the yeast cream.

10. The device according claim 9 , wherein it comprises for each of said interchangeable transport reservoirs:
an outlet conduit for dosing of the yeast cream, said conduit connecting the outlet opening of the interchangeable transport reservoir to a dispensing opening outside the refrigerated chamber; and
an opening/closing mechanism for said outlet conduit, enabling the opening of said outlet conduit for the dispensing of the yeast cream and enabling the closure of said outlet conduit so as to stop the dispensing of the yeast cream from said interchangeable transport reservoir.

11. The device according to claim 1 , wherein said piece of furniture comprises a refrigerated compartment which contains at least two interchangeable transport reservoirs containing stable yeast cream and having a total internal volume of between 1 and 100 liters and an outlet opening for the yeast cream.

12. The device according claim 11 , wherein it comprises for each of said interchangeable transport reservoirs:
an outlet conduit for dosing of the yeast cream, said conduit connecting the outlet opening of the interchangeable transport reservoir to a dispensing opening outside the refrigerated chamber; and
an opening/closing mechanism for said outlet conduit, enabling the opening of said outlet conduit for the dispensing of the yeast cream, and enabling the closure of said outlet conduit so as to stop the dispensing of the yeast cream from said interchangeable transport reservoir.

13. The device according to claim 1 , wherein the stable yeast cream has a dry matter content of between 12 and 25 % by mass.

14. The device according to claim 1 , wherein the stable yeast cream is a stabilized yeast cream.

15. The device according to claim 1 , wherein the yeast cream comprises one or more ingredients, additives or technological auxiliaries having a role of bread improver and/or a role of maintaining homogeneity.

16. Installation for dosing stable yeast cream in a bakery, comprising at least two devices according to claim 1 .

17. The device according to claim 1 , wherein the stable yeast cream has a dry matter content of at least 12% by mass.

18. The device according to claim 1 , wherein the collapsible bag is a polyethylene bag having a wall thickness comprised between 10 and 200 μm.

19. The device according to claim 18 , wherein the collapsible bag has a wall thickness comprised between 25 and 50 μm.

20. The device according to claim 1 , wherein said collapsible bag is provided with a reinforcing layer or pouch.

21. A method of dosing of bakers' yeast cream in a bakery containing a device comprising:
a piece of furniture having a refrigerated compartment having an internal temperature regulated at between −2° C. and 12° C.;
an indicator showing the temperature inside said refrigerated compartment;
an alarm alerting when the temperature inside the refrigerated compartment does not correspond to a determined temperature range;
an interchangeable transport reservoir located in the refrigerated compartment and containing stable yeast cream, said reservoir having a total internal volume of between 1 and 100 liters and an outlet opening for the yeast cream;
an outlet conduit, said conduit connecting the outlet opening of the interchangeable transport reservoir to a dispensing opening outside the refrigerated chamber; and
an opening/closing mechanism enabling the opening and closing of the outlet conduit,
said device being devoid of any stirrer for mixing the content of the transport reservoir,
said interchangeable transport reservoir being a collapsible bag,
the method including dispensing a dosed quantity of yeast cream from the interchangeable transport reservoir via the dispensing opening and the outlet conduit by:
opening the outlet conduit by means of the opening/closing mechanism for the dispensing of the yeast cream; and
closing the outlet conduit by means of the opening closing mechanism in order to stop the dispensing of the yeast cream,
wherein the collapsible bag permits the dispensing of a dosed quantity of yeast cream via the dispensing opening by activation of the opening/closing mechanism without entry of gas from outside the collapsible bag into th
