The composted tea brewing system 2 and the hydroponic storage tank 3 are arranged in a closed loop. The composted tea brewing system 2 includes a composted tea brewing storage tank 4 for storing a certain amount of compost and water for brewing composted tea. The composted tea brewing storage tank 4 has an open top and a lower port with a conical opening 5. Water can flow into the composted tea brewing storage tank 4 through the conical opening 5, or composted tea can be discharged from the composted tea brewing storage tank 4 through the conical opening 5.

[0013] The filter 6 has an outlet connected to the conical opening 5. The peripheral wall of the filter 6 has multiple holes through which the nutrient enhancement liquid can enter the filter 6 and exit the compost tea brewing storage tank 4 through the conical opening 5. The filter 6 can prevent compost particles from entering the conical opening 5 to prevent blockage of the closed-loop brewing device 1.

[0014] In the illustrated embodiment, the compost tea brewing storage unit 4 includes an air pump 7 in fluid communication with a first vent pipe 8 and a second vent pipe 9, which force air into the lower part of the compost tea brewing storage unit 4 to agitate the compost for uniform distribution. The first vent pipe 8 and the second vent pipe 9 have a lower connector 12 and an upper connector 13. The lower connector 12 is in fluid communication with the interior of the compost tea brewing storage unit 4, and the upper connector 13 is in fluid communication with the interior of the compost tea brewing storage unit 4 to discharge aerated liquid into the compost tea brewing storage unit 4. The air pump 7 is electrically connected to an electrical control box 14, which is connected to a power source. When the air pump 7 is turned on, air is injected into the lower ports 10 of the first vent pipe 8 and the second vent pipe 9, causing liquid from the compost tea brewing storage unit 4 to flow upwards in the first vent pipe 8 and the second vent pipe 9 and be discharged through the upper connector 13 of the compost tea brewing storage unit 4.

[0015] In the illustrated embodiment, the compost tea brewing storage unit 4 is raised and lowered by a platform 15.

A filter valve 33 controls the flow rate from the filter 30 into the conduit 18.

[0019] See Figure 2This is a schematic diagram of a compost tea brewing apparatus connected to a hydroponic device. In the illustrated embodiment, the hydroponic storage tank 3 has a connecting pipe 35 that is piped to the inlet port 36 of the hydroponic device 34. A second delivery pump 37 pumps liquid from the hydroponic storage tank 3 to the inlet port 36 of the hydroponic device 34 through the connecting pipe 35. One end of the connecting pipe 35 is connected to a first T-shaped pipe 38, and the other end is connected to the inlet port 36 of the hydroponic device 34. The outlet 39 of the hydroponic device 34 is piped to a second return pipe 40, through which liquid flows into the hydroponic storage tank 3.

[0020] In the illustrated embodiment, a first delivery pump 27 is connected to a second T-tube 41. A connecting valve 42 is connected between the first T-tube 38 and the second T-tube 41 to control the flow between the compost tea brewing storage unit 4 and the hydroponic storage unit 3. An intermediate pipe 43 connects the second T-tube 41 and a third T-tube 44. The third T-tube 44 branches the flow between the first vent pipe 8 and the second vent pipe 9. The flow from the third T-tube 44 to the first vent pipe 8 is controlled by a first control valve 45. The flow from the third T-tube 44 to the second vent pipe 9 is controlled by a second control valve 46. Therefore, the relative flow rates into the first vent pipe 8 and the second vent pipe 9 can be controlled by the first control valve 45 and the second control valve 46.
