The cycle principle consists in measuring total gas release and gas
release less its carbon dioxide trapped in the soda lime cartridge.
The difference between the two gas release curves gives the
quantity of carbon dioxide given off by the dough during the test.

Cycle description:
1. Direct cycle
Electrovalves B and B’ isolating the absorbent (soda lime
cartridge) in the direct circuit are closed, as well as circuit
bleed electrovalve C. Direct circuit isolation electrovalve A is
open. Pressure increase due to swelling of the fermenting
dough is measured by the electronic sensor.
2. Bleed cycle
Once the pressure measurement has been recorded,
electrovalves A,B,B’ are closed and electrovalve C opens to
bleed the circuit and set it to atmospheric pressure.
Electrovalve C then closes.
3. Indirect cycle
Direct circuit isolation electrovalve A and bleed electrovalve C
are closed. Electrovalves B and B’ isolating the soda lime
cartridge and the indirect circuit are open. The increase in
pressure due to dough swelling is measured without the
carbon dioxide that has been trapped by the soda lime.
4. Bleed cycle
A new bleed cycle is run just as described in point 2.
5. A direct cycle is then activated and so on until completion of the
time programmed in the protocol.
