    [0002] Procedure for the preparation of sourdough and bio-generator to carry it out
    [0003] TECHNICAL SECTOR
    [0005] The present invention refers to a sourdough bio-generator, provided with an automated program in order to obtain sourdough for making bread.
    [0007] The object of the invention is to provide a process for making sourdough in which the performance, viability and vitality of the cells that participate in the process are not affected, for which it consists of two differentiated phases, a first phase of multiplication of the microorganisms ( starters) involved in the generation of sourdough, and a second phase of controlled addition of flour.
    [0009] BACKGROUND OF THE INVENTION
    [0011] The current way of generating sourdough for making bread begins with the incorporation of all the flour to be used on a tank, where the mixing takes place with the different components that participate in the formation of the sourdough. In this process, the performance, viability and vitality of the cells is diminished due to the high water-trapping power of the flour.
    [0013] EXPLANATION OF THE INVENTION
    [0015] The bio-generator of sourdough that is recommended solves in a fully satisfactory way the problems previously exposed, based on a simple but effective solution.
    [0017] For this, the sourdough bio-generator of the invention has the particularity of adding the flour in a controlled manner, allowing the microorganisms ( starters) resulting from the multiplication phase to progressively adapt to the new conditions, significantly improving the yields in the generation of the product of interest.
    [0018] The first phase of multiplication or growth of the starters begins with the addition of water, a carbon source and selected nutrients. These compounds are added automatically thanks to a system made up of load cells, solenoid valves and hoppers.
    [0020] The bio-generator consists of a tank with at least one scraper blade driven by a motor, also assisted by a pump to recirculate the content of the bio-generator, capturing bacterial culture from the lower zone of the bio-generator tank and recirculating it to return to introduce it in the same by its upper part, thus ensuring the correct homogenization of the mixture contained in the biogenerator and helping to break up the lumps that may have formed, thanks to the mechanical action of the pump during the passage from culture to through it, and there is also an inlet of gases (air / O2 / N2 / CO2), whose flow is a function of the volume of liquid contained within the tank, all of which favors, through the agitation generated, the mixture of the compounds previously cited. On the other hand, it also includes an external water recirculation jacket with which to control the temperature inside the tank. The essential parameters of the process are monitored and controlled thanks to the incorporation of pH, Ta and% dissolved oxygen probes.
    [0022] Once the desired conditions of Ta, pH and% of oxygen have been reached, the corresponding amount of starter will be automatically dispensed , starting the multiplication phase, which will last between 4 and 10 hours depending on the microorganisms used. During this multiplication process, the stirring of the blades is vigorous in order to favor with said mixing the homogeneity of the crop and accessibility of the nutrients, the recirculation caused by the pump being equally intense, carrying out at the same time an injection of gases whose flow is a function of the volume of liquid contained in the bio-generator tank, also controlling the temperature to keep it close to 30 ° C.
    [0024] After the first phase of the process, the controlled and gradual addition of flour is activated to generate the sourdough. The duration of this second phase can range between 10 and 40 hours depending on the characteristics desired in the sourdough to be generated, during which time the recirculation of the content of the bio-generator tank can be carried out by means of the aforementioned pump.
    [0025] Once the sourdough generation process is finished, it can be dosed online through an automated system of electro-valve and addition pump.
    [0027] Said sourdough bio-generator will have a water inlet and will incorporate adjacent hoppers or tanks for application of the source of carbon, nutrients and starters, which are incorporated together in a first phase, to later carry out the incorporation of the flour as previously mentioned.
    [0029] DESCRIPTION OF THE DRAWINGS
    [0031] In order to complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a drawing is attached as an integral part of said description. For illustrative and non-limiting purposes, the following has been represented:
    [0033] Figure 1.- Shows a schematic diagram of the structure of a sourdough bio-generator made in accordance with the object of the present invention.
    [0035] PREFERRED EMBODIMENT OF THE INVENTION
    [0037] In view of the outlined figure, it can be seen how the sourdough bio-generator of the invention is constituted from a tank or reservoir (1) that receives the different components that will be explained below, being implemented by a pump ( 19) for the recirculation of the contents of the tank (1) of the bio-generator, through a conduit or pipe (20), from the lower zone of the tank (1) to the upper zone where it is re-introduced, with the consequent homogenization of the mixture and helping to disintegrate the lumps thanks to the mechanical action of the pump during the passage of the crop through it, and inside which there is at least one scraper blade (2) driven by a motor (3), and whose scraper blade incorporates diffusers (4) for air / O2 / N2 / CO2, driven by a compressor (16) or by any other gas pressure supply system, with its corresponding dryer and gas filters, complemented with a jacket of refrigeration (5) and with a chiller unit liquid (6) for the cooling jacket (5), including an oxygen sensor (7) and a temperature sensor (9) that will allow knowing when to act on said parameters to keep them within the appropriate margins, as well as a pH sensor (8).
    [0039] The diffusers (4) for air / O2 / N2 / CO2 could also be arranged independently of the scraper blade (4), being located anywhere else in the tank (1).
    [0041] The tank (1) will have a water inlet (11) connected to a supply source and incorporates a small hopper (10) for aggregation, in a first operational phase of carbon source, nutrients and starter (yeast or lactic bacteria ), these components that are in their respective tanks (12), (13) and (14), while in another independent tank (15) the flour is established, which will be incorporated through its own hopper (10 ' ) to the tank (1), where it will be mixed in a second phase with the previously described components of the initial phase.
    [0043] The tank (1) will have an overpressure valve (17) to evacuate gases in the event of excess pressure in its interior, as well as a liquid outlet tap (18) for taking samples.
