Further, for example, the milk supply pipe 15 and the F-type joint of the mixing portion 32 are connected by inserting the elastic milk supply pipe 15 into the non-elastic F-type joint, so that a step is formed in the connection portion. It ends up. Therefore, by transporting the cleaning liquid in the opposite direction, the cleaning liquid can be distributed even to the stepped portion, and the cleaning can be performed in detail.

After that, the control device 70 stops the gear pump 33 for a predetermined time, retains the cleaning liquid inside the milk supply pipe 15, and performs cleaning by so-called immersion.
After that, the control device 70 drives the gear pump 33 in the forward direction to send the cleaning liquid to the milk supply pipe 15, and discharges the cleaning liquid to the disposal container 81 via the milk nozzle 35. At this time, the control device 70 drives the air pump 40, opens the air solenoid valve 41, sends air to the milk supply pipe 15, and performs cleaning by bubbling.
By such an operation, the cleaning process with the cleaning liquid is completed.

Next, the rinsing operation will be described.

Next, the finishing rinsing operation will be described.
The control device 70 stops the gear pump 33 and opens the hot water solenoid valve 50. As a result, the rinse water is supplied from the hot water tank 21 from the mixing unit 32 via the hot water rinse supply pipe 53 and the air / hot water supply pipe 44, and the rinse water is a cleaning container from the milk supply pipe 15 via the pinch valve 31. It is discharged to 80 and rinsed on the upstream side of the mixing section 32.
Subsequently, the control device 70 closes the pinch valve 31 and rotationally drives the gear pump 33 in the forward direction. As a result, rinse hot water is supplied from the hot water tank 21 from the mixing section 32 via the hot water rinse supply pipe 53 and the air / hot water supply pipe 44, and the rinse hot water is supplied from the milk supply pipe 15 to the gear pump 33 and the temperer 34, respectively. It is discharged from the milk nozzle 35 to the disposal container 81 via the milk nozzle 35, and rinses on the downstream side of the mixing section 32.

Next, the control device 70 stops the gear pump 33 and opens the pinch valve 31, and in this state, drives the air pump 40 and opens the air solenoid valve 41 to open the inside of the milk supply pipe 15. The rinse water remaining in the cleaning container 80 is discharged to the cleaning container 80.
Further, the control device 70 remains inside the milk supply pipe 15 by driving the gear pump 33, closing the pinch valve 31, driving the air pump 40, and opening the air solenoid valve 41. The rinse water is discharged into the disposal container 81. In the present embodiment, the gear pump 33 is controlled to be driven, but since it is possible to flow through the gap of the gear pump 33, the gear pump 33 is stopped without being driven in order to prolong the life of the gear pump 33. You may.
Then, the control device 70 operates the electromagnetic pump 60, switches the steam three-way valve 63 to the milk nozzle 35 side, supplies steam from the steam boiler 61 to the milk nozzle 35, and thereby enters the steam pipe 62. The rinse water is discharged to the disposal container 81.

The above operation completes the cleaning and rinsing of the milk supply pipe 15. After that, the cleaning container 80 and the disposal container 81 are removed.
