This is especially done by a relaxation of the must in a flash pot working under vacuum.
- the organic compounds are flashed and entrained with water, in feet of the flash pot the must cooled by the evaporation of the solvents and water is recycled to the fermenter at a temperature such that it absorbs the exotherm of the fermentation.
- the pressure is adjusted so as to obtain the temperature giving the thermal equilibrium to the fermenter. According to the needs, we bring calories to the flash.

- step b) flash evaporation of the liquid separated in step b), and obtaining in the gaseous phase of the organic products
- the process is preferably carried out continuously or semi-continuously.
- fermentation is meant a biochemical reaction of conversion of the chemical energy contained in a carbon source, in particular glucose, into another form of energy directly usable by the cell, in particular in the absence of oxygen.
- the fermentation according to the invention relates in particular to lactic fermentation and preferably to alcoholic fermentation which is the result of a metabolic chain which converts fermentable sugars, in particular yeasts, into alcohol and carbon dioxide with the release of heat.
- the fermentation according to the invention leads to the production of the organic products of interest.
- biomass means all living materials, usually microorganisms, present in the fermentation medium.
- the fermenter used according to the present invention is a technological unit in which microorganisms, such as yeasts, bacteria, microscopic fungi, algae, or animal or plant cells, are multiplied for the bioconversion of an organic molecule of interest.
- This bioreactor generally controls the culture conditions such as temperature, pH, and aeration. In the fermenter, the temperature is generally between 30 and 45 ° C.
- the separation of the biomass is generally carried out in step b) before flash evaporation of step c).
- filtration, ultrafiltration, decantation, centrifugation and / or ultracentrifugation can be carried out.
- the arrival of the mill in the system allowing the flash evaporation is preferably carried out in an area having a pressure equivalent to or equal to the pressure of the fermenter.
- the barometric height can allow a pressure gradient between 0.5 and 1 bar.
- the circulation of the mout can for example be carried out by a pump.
- the liquid obtained, also called liquid separated in step b), corresponds to the wort as defined previously essentially free of biomass.
- This liquid generally has the same temperature as that of the fermenter.
- the filtrate liquid is conveyed to the flash evaporation stage and the residue or retentate is returned to the fermenter.
- Tangential ultrafiltration systems are generally used on an external pressure circulation loop. These ultrafiltration systems, with a cut-off threshold of the order of 0.01 ⁇ generally, usually operate under PTM transmembrane pressures of the order of 1 to 3 bar.
- the sizing of such an ultrafiltration system depends on the quantity of organic products to be extracted from the reactor and the duration during which this extraction must be made. These parameters determine the volume of filtrate to be produced for flash evaporation.
- the circulation rate of the wort inside the ultrafiltration module is generally between 2 and 5 m / s.
- the membranes used are generally tubular mineral type having the advantage of being able to undergo effective cleaning treatments and be insensitive to clogging.
- the flash evaporation of step c), or flash flash consists of placing the liquid in a vacuum tank, in particular with a pressure of between 0.001 and 0.9 bar. Vacuuming lowers the saturation temperature and evaporates some of the liquid. The evaporation will be done by taking energy from the mixture and thus cool it.
- the vacuum flash evaporation process has been widely used for several decades in various industries. It is found in various applications such as desalination of seawater, the concentration and pasteurization of milk or the treatment of wastewater loaded with soluble oils.
- a gas-liquid separator such as a flash tank or expansion tank, also called a flash pot.
- a heat exchanger can be added in or next to the gas-liquid separator, depending on the needs energy, to heat or cool the flash evaporation medium.
- a tubular or plate exchanger may be used.
- the gas-liquid separator is generally a cylinder with a vertical axis. It comprises, for example, a liquid inlet pipe for the fermenter, an outlet at the base and an outlet at the head.
- the column height may be a function of the desired barometric height as previously explained.
- the gas-liquid separator may comprise a lining or trays so as to have a few theoretical stages of separation.
- the flash evaporation is preferably carried out at a pressure of between 10 and 200 mbar.
- the temperature during flash evaporation is generally between 10 and 40 ° C.
- the vaporization rate may be between 1 and 70% by weight, preferably between 30 and 60% by weight.
- This separation is preferably carried out without adding any particular external solvent to the compounds resulting from the fermentation.
- the gaseous phase resulting from flash evaporation thus comprises the organic products of interest as well as incondensable dissolved substances such as CO2, H 2 . and CH 4 .
- the gaseous phase is preferably brought to a condensing means, such as a condenser, in particular to separate the residual incondensables organic products of interest.
- a condensing means such as a condenser
- the aqueous phase resulting from the flash evaporation generally comprises water in large quantities and a minority of organic compounds.
- This phase The aqueous solution is preferably recycled to the fermenter, and is especially at a temperature below the temperature of the fermenter, generally a temperature of 5 to 20 ° C lower than the temperature of the fermenter.
- the organic products of interest of the gaseous phase are then isolated by one or more separation techniques known from the state of the art, such as in particular by distillation, liquid-liquid extraction, crystallization and / or adsorption. When the boiling temperatures are very close, it may be advantageous to use a fractional distillation process which consists of several successive refinement steps. It is also possible to introduce part of the distillate at the top of the column in the case of a continuous distillation in order to improve the purity of the vapor phase.
