[0022] like Figure 1 As shown in the preferred embodiment 1, a dual sanitary filter system for yeast extract with ultrasonic high-efficiency backwashing includes a sanitary filter with one working and one standby connected in parallel between the feed pipe and the discharge pipe. Each sanitary filter is equipped with a backwashing pipe. The hot water inlet pipe of the backwashing pipe is connected in parallel with the discharge port of the corresponding sanitary filter, and the hot water outlet pipe of the backwashing pipe is connected in parallel with the feed port of the corresponding sanitary filter. Remote control valves are provided on the hot water inlet pipe, the hot water outlet pipe, the feed pipe, and the discharge pipe.

[0023] Each of the aforementioned sanitary filters is equipped with an ultrasonic vibration device, and the ultrasonic vibration device operates synchronously with the backwash pipeline;

[0024] Pressure gauges are installed on both the feed pipe and the discharge pipe. The pressure gauges are linked to the backwashing pipe and ultrasonic vibration device on the corresponding sanitary filter through an external controller.

[0025] The system determines whether the sanitary filter is clogged based on the pressure difference across the two ends of the pressure gauge. If the pressure difference exceeds the set value, another sanitary filter is switched to operation. For the clogged sanitary filter, the backwash pipeline and ultrasonic vibration device are activated to perform hot water backwashing. At the same time, the ultrasonic vibration device is used to improve the cleaning effect. It can generate vibration during backwashing to break up denatured protein blocks and clean small particles of clogging on the filter screen, reducing the backwash interval, saving water, and reducing material loss. The system also uses a remote control valve to link the opening and closing of the pipeline (i.e., the opening and closing of the corresponding remote control valve) and the start of the ultrasonic vibration device through an external controller and the corresponding pressure gauge, thereby achieving automatic control.

[0026] The feed pipe is provided with a remote control valve, a pressure gauge and a tee connector in sequence along the feed direction on the branch of the feed pipe to the feed inlet of the corresponding sanitary filter. The branch of the feed inlet of the sanitary filter is connected in parallel with the hot water outlet of the backwash pipe through the tee connector.

[0029] The remote control valves are all pneumatic butterfly valves.

[0030] The ultrasonic vibration device comprises a plurality of resonance rings distributed at equal intervals along the axial direction, the resonance rings are concentrically and coaxially sleeved and fixed on the corresponding sanitary filters, and the resonance rings and the corresponding sanitary filters are linked, the resonance rings on the same sanitary filter are connected in parallel with the output end of the corresponding transducer, and the input end of the transducer is connected with the output end of the ultrasonic generator.

[0031] The input ends of the transducers are connected in parallel with the output end of the same ultrasonic generator.

[0032] The resonance rings are at least two, which are arranged at the first end and the tail end of the corresponding sanitary filter.

[0033] The external controller is an external industrial PLC controller.

[0034] As a preferred embodiment 2, the double-channel simultaneous production of the A group and B group filters can be used, when the A group cleaning condition is met, the ultrasonic vibration and hot water backwashing of the A group filter are performed once, when the B group cleaning condition is met, the ultrasonic vibration and hot water backwashing of the B group filter are performed once, in order to ensure the continuity of production, the ultrasonic vibration and hot water backwashing of the A group and the B group cannot be performed simultaneously, but can be performed one by one (ONE BY ONE).

[0035] (1) A group cleaning condition: when the inlet pressure gauge PIA01-outlet pressure gauge PIA02>Pa (set value) and lasts for 3 seconds

[0036] (2) A group performs ultrasonic vibration and hot water backwashing program once: close remote control valves QDA1 and QDA2, open remote control valves QDA3 and QDA4, start ultrasonic generator FSQ and transducer A HNQA, vibrate and backwash Ca (set value) seconds, after Ca seconds, close remote control valves QDA1 and QDA2, close remote control valves QDA3 and QDA4, stop ultrasonic generator FSQ and transducer A HNQA running, and wait for the switching signal, when the B group meets the cleaning condition, open remote control valves QDA1 and QDA2 to switch to the A group running.
