Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
Referring to fig. 1, an embodiment of the present invention provides a novel ectopic fermentation bed, including:
a fermentation bed 10;
the heating pipeline 14 is arranged at the bottom of the fermentation bed 10, and the heating pipeline 14 comprises a water inlet 15 and a water outlet 16;
a rotary stirring blade 12 arranged in the middle of the fermentation bed 10;
a motor 13 for driving the rotary stirring blade 12 to rotate;
a discharge port 11 arranged at one side of the fermentation bed 10;
a first temperature sensor 17 arranged at the bottom of the fermentation bed 10;
a temperature and humidity sensor 18 disposed outside the fermentation bed 10 for acquiring an external temperature and an external humidity; and
a control unit (not shown in the figure), wherein the control unit is used for controlling the heating pipeline 14 to heat the bottom of the fermentation bed 10 to a first preset range when the temperature of the first temperature sensor 17 is lower than a first threshold value; and the control unit is further used for controlling the motor 13 to rotate at different frequencies according to the external temperature and the external humidity. It can be understood that the heating pipeline 14 is controlled to heat the bottom of the fermentation bed 10 to a first predetermined range, so that a dead bed phenomenon caused by too low temperature of the novel ectopic fermentation bed can be prevented; in addition, the fermentation capacity and the fermentation effect on the ectopic fermentation bed are greatly dependent on the evaporation effect on the surface of the fermentation bed; therefore, the present invention further controls the motor 13 to rotate at different frequencies according to the external temperature and the external humidity through the control unit, so that the evaporation effect of the surface of the fermentation bed can be controlled under the conditions of different temperatures and humidity, and the fermentation capacity and the fermentation effect are improved.
Specifically, when the external temperature is higher than the second threshold and the external humidity is higher than a set humidity, the control unit is further configured to control the motor 13 to rotate at a first frequency η 1; when the external temperature is higher than the second threshold and the external humidity is lower than the set humidity, the control unit is further configured to control the motor 13 to rotate at a second frequency η 2; when the external temperature is lower than the second threshold, the control unit is further configured to control the motor 13 to rotate at a third frequency η 3, where η 1> η 2> η 3. In one embodiment, the second threshold is about 30 degrees celsius. It can be understood that if the external temperature is high and the humidity is high, rapid stirring is required to improve the evaporation effect of the surface of the fermentation bed; in addition, when the external temperature is high and the humidity is low, the stirring speed can be reduced to prevent the temperature from being diffused too fast and ensure the evaporation effect on the surface of the fermentation bed. In addition, when the temperature is low, the stirring speed needs to be controlled to prevent the temperature from being diffused too fast, so that the dead bed phenomenon is caused.
As a further improvement, in one embodiment, η 1 is about 360 revolutions per hour, η 2 is about 180 revolutions per hour, and η 3 satisfies η 3-0.006 t3-0.19t2+2.3t-2.6 revolutions per hour. Referring to fig. 2, the data in fig. 2 are obtained by optimizing the rotation speed of the motor according to different temperatures to ensure the evaporation effect of the surface of the fermentation bed during actual use. Wherein the rotation speed at 5 ℃ is about 5 revolutions per hour, the rotation speed at 10 ℃ is about 7 revolutions per hour, the rotation speed at 15 ℃ is about 10 revolutions per hour, the rotation speed at 20 ℃ is about 15 revolutions per hour, and the rotation speed at 25 ℃ is about 30 revolutions per hour. Thus, the above formula is obtained by fitting the data points. In the actual control, in order to avoid complicated calculations, it is also possible to control the rotation at a predetermined rotation speed in different temperature ranges. In one embodiment, the rotation speed is about 5 rpm at 0-5 ℃, about 7 rpm at 5-10 ℃, about 10 rpm at 10-15 ℃, and about 15-20 ℃The rotation speed is about 15 revolutions per hour, and the rotation speed is about 30 revolutions per hour when the temperature is 20-30 ℃.
As a further improvement, the rotating stirring blade 12 includes a first stirring blade and a second stirring blade, which are arranged in a central symmetry manner, wherein the first stirring blade has a first stirring surface 121 for stirring the fermented product upwards, and the second stirring blade has a second stirring surface 121 for stirring the fermented product downwards.
As a further improvement, the second stirring blade is provided at an upper portion of the first stirring blade.
As a further improvement, the set humidity is 40-50%. In one embodiment, the set humidity is 50%.
According to a great deal of practice, the fermentation capacity and the fermentation effect on the ectopic fermentation bed are greatly dependent on the evaporation effect of 20-40 cm on the surface of the fermentation bed, so that in order to obtain good evaporation effect, the height of the rotary stirring blade 12 from the top of the fermentation bed 10 is set to be 20-40 cm as a further improvement. Specifically, the height H between the top of the rotary stirring blade 12 and the top of the fermentation bed 10 can be controlled to be about 15-25 cm, and the height H between the bottom of the rotary stirring blade 12 and the top of the fermentation bed 10 can be controlled to be about 35-45 cm. In one embodiment, H is about 20 cm and H is about 40 cm.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
