Abstract

The present invention is a aroma recovery equipment from gases exhausted of fermentation vats comprising a first recovery group (100) comprising a first condenser (110) operating at a first temperature of recovered aromas; one second recovery group (200) comprising a second condenser (210) operating at a second temperature of recovered aromas; a cooling group (300) to provide cold by a cooling fluid (301) to said first recovery group (100) via a first fluid connection (302) and to said second recovery group (200) via a second fluid connection (303); control means (400) configured to coordinately control the temperature of said first recovery group (100) and the temperature of said second recovery group (200); and a mobile housing (500) containing said first recovery group (100), said second recovery group (200), said cooling group (300) and said control means (400).

First claim

The invention claimed is:

1. An aroma recovery equipment for recovering aromas from exhaust gases from fermentation vats, wherein the aroma recovery equipment comprises:
a first recovery group comprising a first condenser, wherein the first condenser operates at a first outlet gas temperature and receives the exhaust gases from the fermentation vats, the first condenser condenses aromatic molecules generating the aromas into a liquid recovered by an aroma outlet for storing and then exhausts the exhaust gases by a gas outlet of the first recovery group;
a second recovery group comprising a second condenser, wherein the second condenser operates at a second outlet gas temperature and receives the exhaust gases from the gas outlet of the first recovery group, the second condenser condenses the aromatic molecules into a liquid recovered by a second aroma outlet for storing and then exhausts the exhaust gases by a gas outlet of the second recovery group:
a cooling group to provide cold by a cooling fluid to said first recovery group via a first fluid connection means and to said second recovery group via a second fluid connection means;
control means configured to coordinately control a temperature of said first recovery group and a temperature of said second recovery group; and
a housing with displacement means.

2. The aroma recovery equipment according to claim 1 , wherein said first outlet gas temperature of said first condenser is between 0° C and −15° C. and said second outlet gas temperature of said second condenser is between −40° C. and −60° C.

3. The aroma recovery equipment according to claim 1 , wherein said first fluid connection means of the cooling group comprises a first expansion valve connected to said first condenser said first condenser being a flooded condenser that is cooled by expanding the cooling fluid upstream of said first condenser, wherein said first expansion valve is electronically controlled by said control means.

4. The aroma recovery equipment according to claim 1 , wherein said first fluid connection means of the cooling group comprises a first control solenoid valve and a first expansion valve connected in series to said first condenser, said first condenser being a flooded condenser that is cooled by expanding the cooling fluid upstream of said first condenser, wherein said first control solenoid valve is controlled by said control means.

5. The aroma recovery equipment according to claim 1 , wherein said first recovery group includes said first condenser connected to a first heat exchanger connected to a pump connected to a fluid tank connected to said first condenser.

6. The aroma recovery equipment according to claim 5 , wherein said first fluid connection means of the cooling group comprises a first control solenoid valve and a first expansion valve connected in series to the first heat exchanger of the first recovery group, wherein the cooling fluid expands upstream of the first heat exchanger, removing heat from said first recovery group, wherein said first control solenoid valve is controlled by said control means.

7. The aroma recovery equipment according to claim 5 , wherein said first fluid connection means of the cooling group comprises a first expansion valve connected to the first heat exchanger of the first recovery group, wherein the cooling fluid expands upstream of the first heat exchanger, removing heat from said first recovery group, wherein said first expansion valve is electronic and is controlled by said control means.

8. The aroma recovery equipment according to claim 1 , wherein said second fluid connection means of the cooling group comprises a second expansion valve connected to said second condenser, the second condenser being a flooded condenser that is cooled by expanding the cooling fluid upstream of said second condenser, wherein said second expansion valve is electronically controlled by said control means ( 400 ).

9. The aroma recovery equipment according to claim 1 , wherein said second fluid connection means of the cooling group comprises a second control solenoid valve and a second expansion valve connected in series to said second condenser the second condenser being a flooded condenser that is cooled by expanding the cooling fluid upstream of said second condenser, wherein said second control solenoid valve is electronic and controlled by said control means.

10. The aroma recovery equipment according to claim 1 , wherein said second recovery group includes said second condenser connected to a second heat exchanger connected to a pump connected to a fluid tank connected to said second condenser.

11. The aroma recovery equipment according to claim 10 , wherein said second recovery group further comprises a compressor and an expansion tank in parallel, connected on one side to the second heat exchanger and on the other side to a liquid/oil separator connected to a third heat exchanger connected to a liquid accumulator connected to a dehydrating filter connected to a liquid visor connected to a control solenoid valve connected to an expansion valve connected to said second heat exchanger forming a cascade refrigerant cycle.

12. The aroma recovery equipment according to claim 11 , wherein said cascade refrigerant cycle also comprises a pressure relief valve connected in parallel to the compressor and the expansion tank so as to eliminate excess pressure by releasing the cascade refrigerant fluid to the expansion tank.

13. The aroma recovery equipment according to claim 11 , wherein said second fluid connection means of the cooling group comprises a second control solenoid valve and a second expansion valve connected in series to the third heat exchanger of the second recovery group, wherein the cooling fluid expands upstream of the third heat exchanger, removing heat from the cascade refrigerant cycle of the second recovery group, wherein said second control solenoid valve is controlled by said control means.

14. The aroma recovery equipment according to claim 11 , wherein said second fluid connection means of the cooling group comprises a second expansion valve connected to the third heat exchanger of the second recovery group, wherein the coolant fluid expands upstream of the third heat exchanger for removing heat from the cascade refrigerant cycle of the second recovery group, and wherein said second expansion valve is electronic and is controlled by said control means.

15. The aroma recovery equipment according to claim 11 , wherein said cooling group comprises a pressure modulator connected by a first input to a first heat exchanger of the first recovery group and a second input to the third heat exchanger of the second recovery group.

16. The aroma recovery equipment according to claim 10 , wherein said cooling group comprises a pressure modulator connected by a first input to a first heat exchanger of the first recovery group, and wherein said pressure modulator is connected by a second input to:
