Disclosure of Invention
Therefore, the invention provides a preparation method of a biomass drink, which can solve the problem that the fermentation degree and uniformity of each component of the same fermented product are inconsistent due to uneven fermentation environment of microorganisms in animal milk and rice washing water caused by layering or air bubbles when rice washing water and animal milk of a cereal mixture are mixed, and realize control of the fermentation process.
In order to achieve the above purpose, the present invention provides a preparation method of a biomass drink, comprising:
step S1, soaking the grain mixture in warm water to obtain rice washing water, wherein the water temperature is 30-40 ℃, the soaking time is 1-2 h, and the real-time turbidity of the rice washing water after the preset time length is obtained to judge whether to grind the grain mixture in a soaking state;
step S2, adding soaked rice washing water into animal milk in a flowing state to obtain first fermentation liquor, acquiring an image of the first fermentation liquor in real time to judge and select a fermentation mode according to layering conditions of the first fermentation liquor after the first fermentation liquor is subjected to an initial stage for a preset period of time, acquiring a stirring rod rotating speed for controlling the flow rate of the first fermentation liquor according to a difference value between the turbidity of the rice washing water when the soaking is completed and the turbidity of upper liquid of the first fermentation liquor when the dynamic fermentation mode is selected, judging whether to stir the first fermentation liquor according to the area of a bubble layer of the first fermentation liquor when the static fermentation mode is selected, and acquiring stirring parameters of the first fermentation liquor according to the duration of forming the bubble layer;
and S3, when the viscosity of the first fermentation liquor reaches the preset viscosity, adding 20% brown sugar water into the first fermentation liquor to obtain a second fermentation liquor, and standing the second fermentation liquor for 2-3d to obtain the biomass drink.
Further, in the step S1, if the real-time turbidity of the rice washing water after the preset time period is less than the standard preset turbidity, the central control unit determines to roll the grain mixture in the soaked state, and controls to start a first air cylinder penetrating through the side wall of the rice washing tank shell, a first motor connected with the first air cylinder, a second air cylinder symmetrically penetrating through the side wall of the rice washing tank shell with the first air cylinder, and a second motor connected with the second air cylinder, so that the first rolling plate connected with the first motor and the second rolling plate connected with the second motor roll the grain mixture together;
wherein the predetermined duration and the standard predetermined turbidity are determined by the mass of the cereal mixture and the mass of warm water;
the central control unit obtains the use pressure of the first air cylinder and the second air cylinder and the rotating speeds of the first grinding plate and the second grinding plate according to the real-time turbidity of the rice washing water;
the use pressure is inversely related to the real-time turbidity, the rotational speed is positively related to the real-time turbidity, and the use pressure is inversely related to the rotational speed.
Further, when the use pressure of the first cylinder and the second cylinder is equal to or greater than the average value of the standard use pressure and the rated use pressure, and the real-time turbidity of the rice washing water is equal to or greater than the standard preset turbidity which is 0.5 times or greater, the central control unit judges that the cold air supply unit is started.
Further, when the preset rolling time period is passed, the central control unit adjusts the rotating speeds of the first rolling plate and the second rolling plate and the using pressures of the first air cylinder and the second air cylinder according to the difference value between the current turbidity of the rice washing water and the turbidity of the rice washing water before rolling and the running state of the cold air supply unit,
if the difference is smaller than the product of the ratio of the preset rolling time to the soaking time and the standard preset turbidity, and the cold air supply unit is in a non-operation state, the central control unit regulates the using pressure of the first air cylinder and the second air cylinder to be high, regulates the rotating speeds of the first rolling plate and the second rolling plate to be low, and controls the start of the cold air supply unit;
and if the difference is smaller than the product of the ratio of the preset rolling time to the soaking time and the standard preset turbidity, and the cold air supply unit is in an operating state, the central control unit regulates the rotating speeds of the first rolling plate and the second rolling plate.
Further, in the step S2, when all the rice washing water enters the fermentation tank, the central control unit controls the driving motor connected to the inner wall of the side end of the fermentation tank to stop running, and after the preset duration of the initial stage, if the central control unit determines that the first fermentation liquid has a layering condition, and the upper liquid height of the first fermentation liquid is greater than or equal to the maximum layering height threshold, the central control unit selects a dynamic fermentation mode, and restarts the driving motor; if the central control unit judges that the layering condition of the first fermentation liquid does not exist or the upper liquid height of the first fermentation liquid is smaller than the maximum layering height threshold value, the central control unit selects a static fermentation mode,
and when the gray level difference value between the upper surface of the first fermentation liquid and the bottom of the first fermentation liquid in the image of the first fermentation liquid is larger than a preset gray level gradient threshold value, the central control unit judges that layering condition exists in the first fermentation liquid.
Further, when the central control unit selects the dynamic fermentation mode, the rotation speed of the stirring rod connected with the driving motor, which is acquired by the central control unit, is determined by the difference value between the turbidity of the rice washing water and the turbidity of the upper liquid of the first fermentation liquid when the rice washing water is soaked.
Further, when the central control unit selects the static fermentation mode, if the ratio of the area of the bubble layer of the first fermentation liquid to the area of the upper surface of the first fermentation liquid in the fermentation tank is greater than or equal to a preset area ratio, the central control unit determines to start the driving motor.
Further, when the central control unit judges that the driving motor is started, the time length from the occurrence of bubbles to the time when the ratio of the area of the bubble layer of the first fermentation liquid to the area of the upper surface of the first fermentation liquid in the fermentation tank is equal to the preset area ratio is obtained, the rotating speed of the stirring rod is obtained according to the time length, and the rotating speed of the stirring rod is inversely related to the time length.
Further, the central control unit selects an oxygen supply mode for the first fermentation liquid according to the fermentation mode of the first fermentation liquid, wherein,
if the fermentation mode of the first fermentation liquid is the dynamic fermentation mode, the central control unit sets the oxygen supply mode of the first fermentation liquid as continuous oxygen supply;
if the fermentation mode of the first fermentation liquid is the static fermentation mode, the central control unit sets the oxygen supply mode for the first fermentation liquid to be periodic oxygen supply.
The invention provides a biomass drink based on the preparation method, which comprises the raw materials of aqueous solution soaked by grain mixture, animal milk and 20% brown sugar water, wherein,
the grain mixture comprises corn, wheat, soybean, rice, millet and sorghum rice;
the animal milk comprises one of milk, camel milk, goat milk and horse milk;
wherein, the mass of the aqueous solution after the grain mixture is soaked is as follows: animal milk quality: brown sugar water mass=1:2:1.
Compared with the prior art, the invention takes the grain mixture, the animal milk and the brown sugar water as raw materials, adopts the natural biomass raw materials which are easy to obtain, can avoid the side effect of chemical components, is suitable for human body absorption, prepares the biomass drink through secondary fermentation, judges the nutrient substances and the microorganism content in the rice washing water through the turbidity of the rice washing water, and enables the microorganisms and the nutrient substances attached on the surface of the grain mixture to be dissociated in the liquid through rolling the grain mixture so as to increase the solute concentration of the rice washing water; according to the invention, the fermentation mode of the first fermentation liquid is selected according to the layering condition of the first fermentation liquid, and as the rice washing water and the animal milk have certain density difference, the layering condition easily causes uneven distribution of effective substances in the first fermentation liquid, and microorganisms and the effective substances are uniformly distributed by flowing the first fermentation liquid so as to make the fermentation more uniform and full.
In particular, the preset time length is determined by the ratio of the mass of the grain mixture to the mass of the warm water, the larger the mass of the grain mixture is, the more microorganisms and nutrients are attached to the surface of the grain mixture, and the longer the time from the surface of the grain mixture to the liquid is, so that when the turbidity of the rice washing water is high, the grain mixture is not rolled, the broken grain of the grain mixture is prevented from entering the liquid to become solid impurities, and when the turbidity of the rice washing water is low, the rolling of the grain mixture can accelerate the microorganisms and nutrients attached to the surface of the grain mixture to enter the water.
In particular, the invention realizes the adjustment of the rolling degree of the grain mixture by setting the use pressure of the first air cylinder and the second air cylinder and the rotating speeds of the first rolling plate and the second rolling plate, and when the use pressure of the first air cylinder and the second air cylinder is larger, the friction force of the first rolling plate and the second rolling plate on the grain mixture is larger, so that the heat generated by friction can be timely dissipated, and the smaller rotating speeds of the rolling plates are selected to avoid the death of microorganisms on the surface of the grain mixture due to long-time high temperature.
