The invention claimed is: 1. A device for production of a beverage by infusion of a ground product, the device comprising: an infusion chamber (2) able to receive the ground product, a circuit of hot water crossing the infusion chamber (2), and a means for circulating the hot water in the circuit, wherein the circulation means is reversible so that the hot water can be circulated through the infusion chamber (2) during beverage production in the opposite direction. 2. The device according to claim 1, in which the circulation means is a pump (8) whose direction of operation is controlled so as to form the means for reversing the hot water circulation through infusion chamber (2). 3. A coffee machine for use with prepackaged doses (1) of ground coffee, coffee machine comprising the device according to claim 1. 4. A device for production of a beverage by infusion of a ground product, the device comprising: an infusion chamber able to receive the ground product, a circuit of hot water, wherein the hot water circuit includes an extraction circuit (11) crossing the infusion chamber (2) and a peripheral circuit (9) parallel to the extraction circuit (11) between an inlet valve (5), upstream of the infusion chamber (2), and an outlet valve (6), downstream of the infusion chamber (2), wherein the inlet and outlet valves (5, 6) are configured to allow closed loop circulation in the extraction circuit (11) and the peripheral circuit (9). 5. The device according to claim 4, wherein the inlet valve (5) has a line connected to a hot water supply (7). 6. The device according to claim 5, wherein the outlet valve (6) has a line connected to a beverage outlet (10). 7. The device according to claim 4, wherein the extraction circuit (11) and the peripheral circuit (9) have an overall volume corresponding to that of the beverage to be produced. 8. A process for producing a beverage by infusion of a ground product, in which the ground product is introduced into an infusion chamber (2) and hot water is circulated through the infusion chamber (2), wherein, during the production of the beverage, the circulation of hot water is stopped and the direction of the circulation through the infusion chamber (2) is reversed. 9. A device for production of a beverage by infusion of a ground product, the device comprising: an infusion chamber (2) able to receive the ground product, a circuit of hot water crossing the infusion chamber (2), and a means for circulating the hot water in the circuit, wherein the circulation means is a pump that is adapted to be reversible to reverse the hot water circulation through the infusion chamber (2) during beverage production, wherein the hot water circuit includes an extraction circuit (11) crossing the infusion chamber (2) and a peripheral circuit (9) parallel to the extraction circuit (11) between an inlet valve (5), upstream of the infusion chamber (2), and an outlet valve (6), downstream of the infusion chamber (2), wherein the inlet and outlet valves (5, 6) are configured to allow closed loop circulation in the extraction circuit (11) and the peripheral circuit (9). 10. The device according to claim 9, wherein the inlet valve (5) has a line connected to a hot water supply (7).
