Abstract
The invention relates to a lice treatment system for fish, comprising: at least an inlet (1), at least a first separator (2), at least a pipeline (3), at least a second separator (4), at least an outlet (5) and at least a primary heating circuit (7), where the first separator (4) is arranged after the inlet (1) to separate fish and water, where the pipeline (3) extends from the inlet (1) to the outlet (5), where at least a part of the pipeline (3) forms a liquid bath for the fish and is designed for, in processing terms, closed circulation of a treatment liquid, and where the second separator (4) is arranged to separate fish and treatment liquid so that the fish are passed to the outlet (5) for release of treated fish and the treatment water is led to the primary heating circuit (7) that extends back from the second separator (4) to the part of the pipeline (3) forming a liquid bath for the fish. According to the invention, the system comprises a separate outlet (10) from the liquid bath which leads to a secondary, in processing terms, closed heating circuit (9) that is designed to discharge a part of the treatment liquid in the liquid bath and replace it with treatment liquid that has a higher temperature than the treatment liquid that is discharged.
Claims (10)
1. A lice treatment system for fish, comprising: at least an inlet (1), at least a first separator (2), at least a pipeline (3), at least a second separator (4), at least an outlet (5) and at least a primary heating circuit (7), where the first separator (4) is arranged after the inlet (1) to separate fish and water, where the pipeline (3) extends from the inlet (1) to the outlet (5), where at least a part of the pipeline (3) forms a liquid bath for the fish and is designed for, in processing terms, closed circulation of a treatment liquid, and where the second separator (4) is arranged to separate fish and treatment liquid so that the fish are passed to the outlet (5) for release of treated fish and the treatment water is led to the primary heating circuit (7) that extends back from the second separator (4) to the part of the pipeline (3) forming a liquid bath for the fish, c h a r a c t e r i s e d i n that the system further comprises a separate outlet (10) from the liquid bath which leads to a secondary, in processing terms, closed heating circuit (9) that is designed to discharge a part of the treatment liquid in the liquid bath and replace it with treatment liquid that has a higher temperature than the treatment liquid that is discharged.
A lice treatment system according to claim 1, wherein the primary heating circuit (7) comprises a heating element (8), a filter, a buffer tank and a circulation means (10).
A lice treatment system according to claim 2, wherein the circulation means (10) comprises a least one selected from the group comprising pumping means, suction means, vacuum means.
A lice treatment system according to claim 2, wherein the secondary heating circuit (9) uses the heating element (8) that is used in the primary heating circuit (7).
A lice treatment system according to claim 4, wherein the secondary heating circuit (9) comprises a circulation means (10; 10').
A lice treatment system according to claim 4, wherein the secondary heating circuit (9) also runs via the filter and the buffer tank of the primary heating circuit (7).
A lice treatment system according to claim 1, wherein the secondary heating circuit (9) comprises a separate heating element (8').
8. A lice treatment system according to claim 7, wherein the heating element (8') in the secondary heating circuit (9) comprises one from the group: heat exchanger, immersion heater, heating plate, induction heating element, microwaves.
9. A lice treatment system according to claim 7, wherein the secondary heating circuit (7) runs via a separate filter and a separate buffer tank.
10. A lice treatment system according to claim 5, wherein the circulation means (10; 10') in the secondary heating circuit (9) comprises at least one selected from the group comprising: pumping means, suction means, vacuum means.
