Growth-promoting micro-organism culture concentrated in a secondary container with feed-back to separate primary culture seed tank

摘要

A culture container (1) generates a supply of growth-promoting micro-organisms in liquid, is new. The container has a fluid discharge (4) to a culture concentration/enrichment unit (9) with a feed-back tube (17) for micro-organism seed culture refreshment to the container (1). The enrichment unit (9) is located outside the container (1) and above the container fluid surface (P). The enrichment unit has a chamber holding an aerobic compost fermentation medium esp. molasses and a sieve preventing compost discharge. A peristaltic radial pump drives the feed-back arrangement for fluid with re-seeding micro-organisms. Effluent heat from the pump helps to maintain the culture temperature.
