The semi continuous extraction reduces the down time and bacteria pollution in the system.
The CO2 flows continuously in the circuit, preventing the accumulation of Dirt and Bacteria.
In the semi-continuous extraction process, the extraction begins with the extractor 1 and proceeds with the extractor 2.
Then from the extractor 2 it proceeds to the extractor 1 and so on. It newer stop until the production manager decides to clean the system.
The semi continuous process gives many Advantages:
The CO2 is always circulating: bacteria and dirt do not deposit in the circuit
The fast closing system reduce to 5 minutes unlading/reloading the canisters
The production per day is increased of 30% if compared to a single extractor system
With 25% higher output per day, the return on the investment is greatly advantaged.
