Technical Field

[0001] This application relates to the technical field of material fermentation, and particularly relates to a fermentation device and a temperature control method for the fermentation device. Background Art

[0002] When fermenting materials such as food waste, perishable waste, and feces, it is necessary to heat the materials to provide an initial temperature so that the materials are at a temperature suitable for fermentation. In addition, during the fermentation process of the materials, new materials are added to the fermentation device, which causes the temperature of the materials to decrease. Therefore, it is necessary to heat the materials so that the materials are further at a temperature suitable for fermentation.

[0003] However, the fermentation devices in the related art only use heating devices for heating, resulting in relatively high energy consumption. Summary of the Invention

[0073] Hereinafter, exemplary embodiments of the present application will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be completely conveyed to those skilled in the art.

[0074] When fermenting materials such as kitchen waste, perishable waste, and feces, it is necessary to heat the materials to provide an initial temperature so that the materials are at a temperature suitable for fermentation. In addition, during the fermentation process of the materials, new materials are added to the fermentation equipment, which causes the temperature of the materials to decrease. Therefore, it is necessary to heat the materials so that the materials are further at a temperature suitable for fermentation.

[0075] However, the fermentation equipment in the related art only uses the heating equipment for heating, resulting in relatively high energy consumption.

[0076] The present application aims to at least solve the problem that the fermentation equipment in the related art only uses the heating equipment for heating, resulting in relatively high energy consumption.

[0077] To this end, an embodiment of the present application provides a fermentation equipment 100, which can use the light energy generated by light to heat the materials, thereby reducing energy consumption.

[0078] An embodiment of the present application also provides a temperature control method for the fermentation equipment.

[0079] Hereinafter, the fermentation equipment 100 and the temperature control method for the fermentation equipment according to the embodiments of the present application will be introduced with reference to the accompanying drawings.

[0080] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the fermentation device 100 of the embodiment of the present application includes a housing 1, a fermentation chamber 2, a heating assembly 3, a transparent plate 4, a temperature sensor (not shown in the figure), and a control module (not shown in the figure). The fermentation chamber 2 is disposed inside the housing 1. The fermentation chamber 2 includes a chamber body 21. The chamber body 21 defines a receiving cavity 211 for fermenting materials. An opening 2113 is formed at the upper end of the receiving cavity 211. The heating assembly 3 includes a bottom plate 31, a heating medium (not shown in the figure), and a heater 32. The bottom plate 31 is disposed on the chamber body 21 and defines a partition layer 311 between the bottom plate 31 and the bottom wall of the chamber body 21. The heating medium is disposed in the partition layer 311. At least a part of the heater 32 is disposed in the partition layer 311 and can heat the heating medium. The transparent plate 4 is disposed at the upper end of the housing 1. The transparent plate 4 is disposed opposite to the opening 2113. The transparent plate 4 is used for transmitting light and enabling the light to heat the materials in the receiving cavity 211. The temperature sensor is disposed in the receiving cavity 211. The control module is in signal connection with the temperature sensor and is electrically connected to the heater 32. The control module is used for receiving the signal of the temperature sensor and controlling the heater 32 to be turned on or off according to the signal.

[0081] The transparent plate 4 is disposed at the upper end of the housing 1. The transparent plate 4 is disposed opposite to the opening 2113. The transparent plate 4 is used for transmitting light and enabling the light to heat the materials in the receiving cavity 211. Thus, when sunlight irradiates the transparent plate 4, it can pass through the transparent plate 4 and irradiate the materials located in the receiving cavity 211 through the opening 2113, thereby being able to heat the materials.

[0082] A partition layer 311 is defined between the bottom wall of the chamber body 21 and the bottom plate 31. The heating medium can be carried through the partition layer 311. The heater 32 heats the heating medium, and the heating medium heats the bottom wall of the chamber body 21, thereby being able to heat the materials in the receiving cavity 211. By indirectly heating through the heating medium, it can make the heat generated by the heater 32 diffuse more evenly into the receiving cavity 211, thereby being able to improve the heating effect.

[0083] The heating assembly 3 can heat the materials in the case of insufficient light, so that the temperature in the receiving cavity 211 can be at a temperature suitable for fermentation.

[0084] The temperature sensor can detect the temperature in the receiving cavity 211, and the control module can control the heater 32 according to the signal of the temperature sensor, thereby being able to adjust the temperature in the receiving cavity 211.

[0085] The fermentation device 100 of this embodiment is provided at the upper end of the outer shell 1 through a transparent plate 4. The transparent plate 4 is disposed opposite to the opening 2113. The transparent plate 4 is used to transmit light and enable the light to heat the materials in the accommodation chamber 211. Thus, when sunlight shines on the transparent plate 4, it can pass through the transparent plate 4 and irradiate the materials located in the accommodation chamber 211 through the opening 2113, thereby heating the materials. The heating assembly 3 can heat the materials when the light is insufficient, so that the temperature in the accommodation chamber 211 can be maintained at a temperature suitable for fermentation. The temperature sensor can detect the temperature in the accommodation chamber 211, and the control module can control the heater 32 according to the signal of the temperature sensor, thereby adjusting the temperature in the accommodation chamber 211. Thus, the fermentation device 100 of this embodiment can be heated in a combination of multiple ways, thereby reducing energy consumption.

[0086] Specifically, the heating medium is heat-conducting oil.

[0087] Combined Figure 4 with Figure 5 As shown, in some embodiments, the inner surface and the outer surface of the bottom wall are both arc surfaces. The inner surface and the outer surface of the bottom plate 31 are both arc surfaces.

[0088] By making the inner surface and the outer surface of the bottom wall both arc surfaces, the contact area between the bottom wall and the materials can be increased, thereby improving the heating effect.

[0089] By making the inner surface and the outer surface of the bottom plate 31 both arc-shaped, the shape of the bottom plate 31 can be adapted to the shape of the bottom wall, and further the thickness of the interlayer 311 can be made more uniform, so that the heating medium is heated evenly.

[0090] Combined Figure 3 with Figure 4 As shown, in some embodiments, the accommodation chamber 211 includes a feeding chamber 2111 and a discharging chamber 2112. The feeding chamber 2111 and the discharging chamber 2112 are separated by a partition plate 212. A connecting hole 2121 penetrating the partition plate 212 is provided at the upper end of the partition plate 212. The feeding chamber 2111 and the discharging chamber 2112 are both communicated with the connecting hole 2121. The connecting hole 2121 is configured to enable the dust in the feeding chamber 2111 to enter the discharging chamber 2112;

[0091] The fermentation bin 2 further includes a stirring assembly 22. The stirring assembly 22 includes a stirring shaft 221 and a first stirring paddle 222. The stirring shaft 221 is rotatably disposed in the bin body 21. At least part of the stirring shaft 221 is located in the feeding chamber 2111 and is connected to the first stirring paddle 222. The first stirring paddle 222 is configured to stir fresh materials and fermented materials, and is further configured to break and lift the fermented materials to convert the fermented materials into dust.

[0092] Add fresh materials into the feed chamber 2111 so that the fresh materials in the feed chamber 2111 are fermented. During the fermentation process, microorganisms generate heat energy, which can kill the eggs in the fresh materials. Moreover, during the fermentation process, the water content in the fresh materials decreases, and some adhesives in the fresh materials are gradually decomposed. After the fresh materials are fermented into fermented materials, due to the low water content and adhesive content, the weight of the fermented materials is small and they are easy to disintegrate.

[0093] Drive the first stirring paddle 222 to rotate through the stirring shaft 221. Under the action of the first stirring paddle 222, part of the fermented materials in the feed chamber 2111 are broken and lifted, so that the fermented materials are converted into flying dust. Part of the flying dust enters the discharge chamber 2112 through the connecting hole 2121, and another part of the flying dust settles in the feed chamber 2111 and is thus located at the upper end of the feed chamber 2111. When the materials in the feed chamber 2111 are higher than the bottom end of the connecting hole 2121, the settled flying dust pours into the discharge chamber 2112 through the connecting hole 2121 and thus enters the discharge chamber 2112.

[0094] Another part of the fermented materials is not broken, but due to the light weight of the fermented materials and the heavy weight of the fresh materials, under the stirring action of the first stirring paddle 222, the fresh materials gradually locate at the lower end of the feed chamber 2111, and the fermented materials are at the upper end of the feed chamber 2111. When the materials in the feed chamber 2111 are higher than the bottom end of the connecting hole 2121, the fermented materials pour into the discharge chamber 2112 through the connecting hole 2121 and thus enter the discharge chamber 2112.

[0095] Thus, the fermented materials and fresh materials can be screened and separated, enabling the fermented materials to enter the discharge chamber 2112 from the feed chamber 2111, thereby realizing the separation of the fermented materials. Take the materials through the discharge chamber 2112, and thus the fermented materials can be taken out.

[0096] As Figure 3 shown, in some embodiments, the stirring assembly 22 further includes a second stirring paddle 223 located in the discharge chamber 2112 and a driving motor 224 located outside the bin body 21. At least another part of the stirring shaft 221 is located in the discharge chamber 2112 and is connected to the second stirring paddle 223, and the driving motor 224 is in transmission connection with the stirring shaft 221.

[0097] The fermented materials in the discharge chamber 2112 can be stirred through the second stirring paddle 223, which is convenient for the fermentation and decomposition of the fermented materials.

[0098] As Figure 4As shown, in some embodiments, the heating assembly 3 further includes a baffle 34. The baffle 34 is disposed within the interlayer 311 and divides the interlayer 311 into a first heating layer (not shown in the figure) and a second heating layer (not shown in the figure); the heater 32 includes a first heater 321 and a second heater (not shown in the figure). The first heater 321 is disposed within the first heating layer, and the second heater is disposed within the second heating layer. The first heating layer is disposed opposite to the feed chamber 2111, and the second heating layer is disposed opposite to the discharge chamber 2112. The temperature sensor includes a first temperature sensor and a second temperature sensor. The first temperature sensor is disposed in the feed chamber 2111, and the second temperature sensor is disposed in the discharge chamber 2112; both the first heater 321 and the second heater are electrically connected to the control module, and both the first temperature sensor and the second temperature sensor are signal-connected to the control module.

[0099] Through the first heater 321 and the first heating layer, the feed chamber 2111 can be heated independently. Through the second heater and the second heating layer, the discharge chamber 2112 can be heated independently. Thus, the feed chamber 2111 and the discharge chamber 2112 can be heated independently so that the temperatures within the feed chamber 2111 and the discharge chamber 2112 can meet the fermentation requirements respectively.

[0100] The temperature within the feed chamber 2111 can be detected by the first temperature sensor, and the temperature of the discharge chamber 2112 can be detected by the second temperature sensor. Both the first temperature sensor and the second temperature sensor are signal-connected to the control module. Through the control module, the first heater 321 and the second heater can be controlled for independent heating, so that the temperatures within the feed chamber 2111 and the discharge chamber 2112 can be adjusted independently to meet the fermentation requirements respectively.

[0101] When the light intensity is too high, it will cause the temperature of the material to be too high. In addition, heat is generated during the fermentation process of the material, which easily causes the temperature of the material to be too high. When the temperature of the material is too high, the activity of the fermentation strains will be inhibited.

[0102] For this reason, as Figure 1 shown, in some embodiments, the housing 21 is provided with a heat dissipation opening 213. The heat dissipation opening 213 is communicated with the accommodation chamber 211. The fermentation chamber 2 further includes a first heat dissipation device electrically connected to the control module. The first heat dissipation device is disposed opposite to the heat dissipation opening 213 and can blow air into the accommodation chamber 211 for heat dissipation.

[0103] When the temperature is too high, the control module controls the first heat dissipation device to blow air into the accommodation chamber 211 through the heat dissipation opening 213, thereby being able to reduce the temperature of the material and reduce the probability of the activity of the fermentation strains being inhibited.

[0104] In some embodiments, the fermentation tank 2 includes a circuit component disposed in the tank body 21 and outside the accommodation cavity 211. The fermentation device 100 further includes a second heat dissipation device and a circuit temperature sensor electrically connected to the control module. The circuit temperature sensor is disposed in the circuit component and is signal-connected to the control module. The second heat dissipation device is disposed opposite to the circuit component and can dissipate heat from the circuit component.

[0105] When the temperature of the circuit component is too high, after receiving the signal from the circuit temperature sensor, the control module controls the second heat dissipation device to dissipate heat from the circuit component, thereby cooling the circuit component so that the circuit component can operate normally.

[0106] Combined with Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown in, the temperature control method of the fermentation device according to the embodiment of the present application, the fermentation device 100 includes:

[0107] A housing 1;

[0108] A fermentation tank 2, disposed inside the housing 1. The fermentation tank 2 includes a tank body 21. The tank body 21 defines an accommodation cavity 211 for fermenting materials. An opening 2113 is formed at the upper end of the accommodation cavity 211;

[0109] A heating component 3, including a bottom plate 31, a heating medium, and a heater 32. The bottom plate 31 is disposed on the tank body 21 and defines a partition layer 311 between the bottom plate 31 and the bottom wall of the tank body 21. Both the heater 32 and the heating medium are disposed in the partition layer 311;

[0110] A transparent plate 4, disposed at the upper end of the housing 1. The transparent plate 4 is disposed opposite to the opening 2113. The transparent plate 4 is used to transmit light and enable the light to heat the fermenting materials in the accommodation cavity 211;

[0111] A temperature sensor, disposed in the accommodation cavity 211;

[0112] The temperature control method of the fermentation device includes:

[0113] S100. Obtain a first temperature through the temperature sensor;

[0114] S200. Compare the first temperature with a first threshold, where the first threshold is the lower limit value of the temperature suitable for fermentation;

[0115] S300. When the first temperature is less than the first threshold, control the heater to heat;

[0116] S400. When the first temperature is greater than or equal to the first threshold, compare the first temperature with a second threshold, where the second threshold is the upper limit value of the temperature suitable for fermentation;

[0117] S500. When the first temperature is less than or equal to the second threshold, control the heater to stop heating.

[0118] S100. Obtain the first temperature through a temperature sensor.

[0119] The first temperature can reflect the temperature inside the accommodation chamber 211. Thus, the temperature inside the accommodation chamber 211 can be obtained through the temperature sensor.

[0120] S200. Compare the first temperature with the first threshold, where the first threshold is the lower limit value of the temperature suitable for fermentation.

[0121] By comparing the first temperature with the first threshold, it is possible to determine whether the temperature inside the accommodation chamber 211 is suitable for fermentation.

[0122] As some examples, the range of the first threshold is: 15 °C (degrees Celsius) to 35 °C.

[0123] S300. When the first temperature is less than the first threshold, control the heater to heat.

[0124] When the first temperature is less than the first threshold, it indicates that the temperature inside the accommodation chamber 211 is relatively low. Control the heater to heat, so as to raise the temperature of the material, which is beneficial to the fermentation of the material.

[0125] S400. When the first temperature is greater than or equal to the first threshold, compare the first temperature with the second threshold, where the second threshold is the upper limit value of the temperature suitable for fermentation.

[0126] When the first temperature is greater than or equal to the first threshold, compare the first temperature with the second threshold, so as to further determine the temperature state inside the accommodation chamber 211.

[0127] As some examples, the range of the second threshold is: 60 °C (degrees Celsius) to 80 °C.

[0128] S500. When the first temperature is less than or equal to the second threshold, control the heater to stop heating.

[0129] When the first temperature is less than or equal to the second threshold, it indicates that the temperature inside the accommodation chamber 211 is suitable for fermentation. Control the heater to stop heating, so as to reduce energy consumption.

[0130] For the temperature control method of the fermentation equipment in this embodiment, compare the first temperature with the first threshold. When the first temperature is less than the first threshold, control the heater to heat. When the first temperature is greater than or equal to the first threshold, compare the first temperature with the second threshold. When the first temperature is less than or equal to the second threshold, it is possible to make the heater 32 match the light heating, so as to heat the temperature inside the accommodation chamber 211 to a temperature beneficial to the fermentation of the material and reduce energy consumption.

[0131] In some embodiments, the heating assembly 3 of the fermentation device 100 further includes a baffle 34. The baffle 34 is disposed in the interlayer 311 and divides the interlayer 311 into a first heating layer and a second heating layer. The heater 32 includes a first heater 321 and a second heater. The first heater 321 is disposed in the first heating layer, and the second heater is disposed in the second heating layer. The accommodation cavity 211 includes a feed cavity 2111 and a discharge cavity 2112. The feed cavity 2111 and the discharge cavity 2112 are separated by a partition 212. The first heating layer is disposed opposite to the feed cavity 2111, and the second heating layer is disposed opposite to the discharge cavity 2112. The temperature sensor includes a first temperature sensor and a second temperature sensor. The first temperature sensor is disposed in the feed cavity 2111, and the second temperature sensor is disposed in the discharge cavity 2112.

[0132] The first temperature includes a second temperature and a third temperature;

[0133] S100. The step of obtaining the first temperature through the temperature sensor includes:

[0134] Obtaining the second temperature through the first temperature sensor;

[0135] Obtaining the third temperature through the second temperature sensor;

[0136] S200. The step of comparing the first temperature with the first threshold includes:

[0137] Comparing the second temperature with the first threshold;

[0138] Comparing the third temperature with the first threshold;

[0139] S300. When the first temperature is less than the first threshold, the step of controlling the heater to heat includes:

[0140] When the second temperature is less than the first threshold, controlling the first heater to heat;

[0141] When the third temperature is less than the first threshold, controlling the second heater to heat;

[0142] S400. When the first temperature is greater than or equal to the first threshold, the step of comparing the first temperature with the second threshold includes:

[0143] When the second temperature is greater than or equal to the first threshold, comparing the second temperature with the second threshold;

[0144] When the third temperature is greater than or equal to the first threshold, comparing the third temperature with the second threshold;

[0145] S500. When the first temperature is less than or equal to the second threshold, the step of controlling the heater to stop heating includes:

[0146] When the second temperature is less than or equal to the second threshold, control the first heater to stop heating;

[0147] When the third temperature is less than or equal to the second threshold, control the second heater to stop heating.

[0148] Thus, it is possible to control the first heater 321 and the second heater to perform separate heating, so that the temperatures in the feeding chamber 2111 and the discharging chamber 2112 can be independently adjusted, so that the temperatures in the feeding chamber 2111 and the discharging chamber 2112 can meet the fermentation requirements respectively.

[0149] In some embodiments, after S300, when the first temperature is less than the first threshold and the heater is controlled to heat, the temperature control method of the fermentation equipment further includes:

[0150] Obtain the heating time of the heater, and calculate the theoretical temperature rise of the material according to the heating time of the heater;

[0151] Compare the theoretical temperature rise with the third threshold, where the third threshold is the limit value of the temperature rise of the material;

[0152] When the theoretical temperature rise is greater than the third threshold, control the heater to stop heating.

[0153] When the theoretical temperature rise of the material is too large, the heater

[0154] When the theoretical temperature rise is greater than the third threshold and the heater 32 is still heating, it indicates that the temperature sensor may be faulty. Controlling the heater to stop heating can avoid excessive temperature rise of the material, thereby avoiding the inactivation of fermentation bacteria.

[0155] Optionally, calculating the theoretical temperature rise of the material according to the heating time of the heater includes:

[0156] Calculate the calorific value Q of the heater according to the following formula;

[0157] Q = I 2 *R*T

[0158] where I is the current passing through the heater, R is the resistance of the heater, and T is the heating time.

[0159] Calculate the temperature rise ΔT of the material through the following formula:

[0160] Q = m*C*ΔT

[0161] where m is the mass of the material and C is the specific heat capacity of the material.

[0162] As some examples, the range of the specific heat capacity of the material is 1.5 kJ / (kg·K) (kilojoules per kilogram kelvin) to 4 kJ / (kg·K).

[0163] In some embodiments, the bin body 21 is provided with a heat dissipation port 213, the heat dissipation port 213 communicates with the accommodation cavity 211, the fermentation bin 2 further includes a first heat dissipation device electrically connected to the control module, the first heat dissipation device is disposed opposite to the heat dissipation port 213, and can blow air into the accommodation cavity 211 for heat dissipation;

[0164] The temperature control method of the fermentation equipment further includes:

[0165] When the first temperature is less than or equal to the second threshold, control the heater to stop heating and start the first heat dissipation device.

[0166] When the first temperature is less than or equal to the second threshold, it indicates that the temperature in the accommodation cavity 211 is too high. Control the heater 32 to stop heating and start the first heat dissipation device, so as to reduce the temperature of the material and reduce the probability that the activity of the fermentation strains is inhibited.

[0167] In some embodiments, the fermentation bin 2 includes a circuit component disposed in the bin body 21 and outside the accommodation cavity 211. The fermentation equipment 100 further includes a second heat dissipation device and a circuit temperature sensor electrically connected to the control module. The circuit temperature sensor is disposed on the circuit component. The second heat dissipation device is disposed opposite to the circuit component and can dissipate heat from the circuit component.

[0168] The temperature control method of the fermentation equipment further includes:

[0169] Obtain a fourth temperature through the circuit temperature sensor;

[0170] Compare the fourth temperature with a fourth threshold, where the fourth threshold is the upper limit of the temperature of the circuit component;

[0171] When the fourth temperature is greater than the fourth threshold, start the second heat dissipation device.

[0172] When the fourth temperature is greater than the fourth threshold, it indicates that the temperature of the circuit component is too high. Control the second heat dissipation device to dissipate heat from the circuit component, so as to cool down the circuit component and enable the circuit component to work properly.

[0173] As some examples, the fourth threshold is 60°C to 70°C.
