ABSTRACT:
The present invention relates to an extraction and brewing machine having a tank, a fan assembly, a base aerator, an extractor head, and an extraction assembly. The extraction assembly has a container for being submerged in liquid held within the tank, and an extraction aerator. The container is comprised of a dome and a filter. The dome defines an interior region for vigorous mixing of air, compost and water. The filter can be a mesh bag. The extraction aerator can have openings near the bottom of the bag. The flow of air though the filter causes a current of liquid, air and microorganisms to exit the chamber. The base aerator aerates all the liquid in the tank. The microorganisms in the tea continue to grow and multiply in the tank after extraction from the chamber, and no particles pass the filter that could jam a spray nozzle.
