The big disadvantage of the developing and currently established digester technology is that the bottom of the digester is flat and thus the deposits and enrich sands, gravel and other contaminants are accumulated at the bottom of the fermenter making the process slow, resulting in:
Figure 1. Conventional digester – internal agitator & heat exchanger
All of this brings significant losses in the economy and efficiency of the plant.
A vortex construction is built at the bottom of the digester, where the sediments are deposited and it is pumped out from the bottom easily with minimal downtime. In addition, the agitators and heat exchangers are present externally and thus eliminating complex factors and safety issues. Thus making our technology:
