[0072] Furthermore, it also includes a two-position three-way valve V03, the first end of the forward cleaning pipeline and the first end of the reverse cleaning pipeline are combined to form a cleaning pipeline inlet, the cleaning pipeline inlet, the pressure hot water source or the pressure steam source are respectively connected to the ports of the two-position three-way valve V03, and the two-position three-way valve V03 is used to select one of the pressure hot water source or the pressure steam source to be connected to the cleaning pipeline inlet, so as to allow the cleaning source (i.e., cleaning medium) for forward cleaning and reverse cleaning.

[0073] Furthermore, a one-way valve Y1 is installed in the forward cleaning pipeline between the pipeline valve V04 and the connection point, and the one-way valve Y1 only allows the liquid in the forward cleaning pipeline to flow from the pipeline valve V04 to the connection point.

[0074] The reverse cleaning pipeline is provided with a one-way valve Y2 between the pipeline valve V05 and the two-position three-way valve V02. The one-way valve Y2 only allows the liquid in the reverse cleaning pipeline to flow from the pipeline valve V05 to the two-position three-way valve V02.

The liquid outlet head is connected to the main pipeline through the two-position three-way valve (V02), and the reverse cleaning pipeline is disconnected from the main pipeline; thereby, the steam positively cleans the front section of the main circuit; and the cleaning time is set to a preset time period t4.

9. A beverage equipment pipeline cleaning method, for the entire main circuit pipeline, characterized in that: The following steps are involved: (1) Hot water reverse cleaning main circuit The cleaning medium is switched to hot water through the two-position three-way valve (V03), the reverse cleaning pipeline is connected to the main pipeline through the two-position three-way valve (V02), the pipeline valve (V05) is opened, the two-position two-way valve (V01) is opened, and the pump (P1) is reversed, so that the hot water is used to reversely clean the entire pipeline of the main circuit; (2) Hot water forward cleaning of the front section of the main circuit Close the pipeline valve (V05), the two-position two-way valve (V01), and the pump (P1) that are opened above, open the pipeline valve (V04), and connect the liquid output head to the main pipeline through the two-position three-way valve (V02); use hot water to positively clean the front section of the main circuit; (3) Steam reverse cleaning main circuit The opened pipeline valve (V04) is closed, the reverse cleaning pipeline is connected to the main pipeline through the two-position three-way valve (V02), and the cleaning medium is switched to steam through the two-position three-way valve (V03); the pipeline valve (V05) is opened, the two-position two-way valve (V01) is opened, and the pump (P1) is reversed, so as to use steam to reversely clean the entire pipeline of the main circuit; (4) Steam positive cleaning of the front section of the main circuit Close the pipeline valve (V05), the two-position two-way valve (V01), and the pump (P1), maintain the cleaning medium switched to steam through the two-position three-way valve (V03), connect the liquid outlet head to the main pipeline through the two-position three-way valve (V02), open the pipeline valve (V04), and use steam to positively clean the front section of the main circuit.

10. A beverage equipment pipeline cleaning method for deep cleaning of the entire main circuit pipeline, characterized in that: The following steps are involved: (1) Place the cleaning agent in the cleaning box and replace the raw material box with the cleaning box; (2) Use cleaning agents to clean the forward cleaning main circuit The pump (P1) rotates forward to open the two-position two-way valve (V01), and connects the liquid outlet head with the main pipeline through the two-position three-way valve (V02); that is, the cleaning agent passes through the pump (P1), the two-position two-way valve (V01), and the two-position three-way valve (V02) in sequence to reach the liquid outlet head; (3) Soaking; The pump (P1), the two-position two-way valve (V01), and the two-position three-way valve (V02) are turned off; the liquid medicine is allowed to remain in the main circuit, and the liquid medicine soaks the main circuit; (4) Use cleaning agent to clean the main circuit again in the forward direction; The pump (P1) rotates forward to open the two-position two-way valve (V01), and connects the liquid outlet head with the main pipeline through the two-position three-way valve (V02); that is, the cleaning agent passes through the pump (P1), the two-position two-way valve (V01), and the two-position three-way valve (V02) in sequence to reach the liquid outlet head; (5) Hot water reverse flushing main circuit; (6) Hot water is used to clean the front section of the main circuit; (7) Steam reverse cleaning main circuit; (8) Steam positive cleaning of the front section of the main circuit.
