Therefore, they cannot be understood as limitations on the present invention.
[0024] Refer to the attached Figure 1-4 A microbial fermentation and culture container includes a fermentation tank body 1, which is generally barrel-shaped. A top cover 2 is fixedly installed on the top of the outer layer 101 of the outer shell of the fermentation tank body 1, and a probe-type temperature detector 4 is vertically inserted into the upper cover 2. The probe in the probe-type temperature detector 4 is arranged in the inner shell 114 of the fermentation tank body 1. The internal cavity of the inner shell 114 is the place where the fermentation tank body 1 cultivates fermentation microorganisms, that is, the inner shell 114 is a container for cultivating liquid culture medium of microorganisms. The probe of the probe-type temperature detector 4 is arranged in the inner shell 114, which is mainly used to measure the temperature of the microorganism fermentation process in the inner shell 114 throughout the process. Four evenly distributed legs 3 are fixedly installed at the lower end of the outer layer 101 of the outer shell.
[0025] In this embodiment, the inner circle of the outer shell layer 101 is fitted with the outer shell middle layer 103, and the inner circle of the outer shell middle layer 103 is fitted with the outer shell inner layer 104. The outer shell layer 101 and the inner shell layer 104 are both made of stainless steel, and an annular splint 105 is fixedly installed on the top of the inner shell layer 104. The outer circle of the annular splint 105 and the inner circle of the outer shell layer 101 fit together, and the inner circle of the annular splint 105 and the outer circle of the inner shell 114 fit together. The outer shell middle layer 103 is made of thermal insulation material, specifically glass wool. The glass wool is extruded and filled between the outer shell layer 101 and the inner shell layer 104, mainly used to increase the thermal insulation performance of the outer shell layer 101 and the inner shell layer 104, that is, the outer shell middle layer 103 can help reduce heat loss, thereby effectively maintaining the temperature inside the inner shell 114 stable, which is especially important for a long fermentation process to prevent temperature fluctuations from affecting fermentation.
[0026] In this embodiment, a barrel-shaped temperature adjustment chamber 108 is reserved between the outer ring of the inner shell 114 and the inner layer 104 of the outer shell. The barrel-shaped temperature adjustment chamber 108 is filled with a heat-conducting liquid, specifically water. A water heater 109 is fixedly installed in the barrel-shaped temperature adjustment chamber 108. After the water heater 109 is powered on, it can heat the water in the barrel-shaped temperature adjustment chamber 108, and then the heated water adjusts the temperature in the inner shell 114. The water heater 109 is connected in series with a current regulator through a wire and is connected to an external power supply. A water heater 109 is fixedly installed on one side of the outer layer 101 of the outer shell. The electrical box and the current regulator are fixedly installed in the electrical box. A VA liquid crystal display 102 is provided on the outside of the electrical box. The VA liquid crystal display 102, the current regulator and the water heater 109 are connected by wires. The VA liquid crystal display 102 is mainly used to display the real-time temperature, the preset temperature and the current size of the touch-screen operation current regulator, thereby controlling the heat generation temperature of the water heater 109. The heating temperature of the water heater 109 is positively correlated with the current. When the current increases, the heating temperature of the water heater 109 will also increase accordingly.
[0027] It should be noted that in winter or in a low-temperature environment, when it is necessary to increase the temperature inside the inner shell 114, the circuit in the water heater 109 can be connected, and the heating temperature of the water heater 109 can be set by the touch case on the VA liquid crystal display 102 to heat the water in the barrel-shaped temperature adjustment chamber 108. The heated water passes through the inner shell 114 to provide additional heat to the liquid culture of the microorganisms therein to maintain the required fermentation temperature.
[0028] In this embodiment, a rotating ring 115 is fixedly installed on the outer ring of the top end of the inner shell 114. The rotating ring 115 is rotatably installed on the annular clamping plate 105. The upper part of the rotating ring 115 is in contact with the annular cover plate 106. The annular cover plate 106 is fixedly connected to the top of the outer shell layer 101, so that the inner shell 114 can be rotatably installed in the inner layer 104 of the outer shell. A plurality of strip grooves 116 are provided on the outer wall of the inner shell 114. The strip grooves 116 are used to increase the contact area and resistance between the outer wall of the inner shell 114 and the water in the barrel-shaped temperature control chamber 108. Similarly, a plurality of strip protrusions 119 are also provided on the inner wall of the strip grooves 116. The strip protrusions 119 are used to increase the contact area and resistance between the inner wall of the inner shell 114 and the liquid culture solution of microorganisms therein. A connecting block 120 is coaxially fixedly installed on the lower bottom surface of the inner shell 114, and a card slot 121 is provided at the lower end of the connecting block 120.
[0029] A waterproof box 118 is fixedly installed on the lower bottom surface of the outer shell layer 101, the middle shell layer 103 and the inner shell layer 104, and a motor 117 is fixedly installed in the waterproof box 118. The output shaft of the motor 117 is arranged vertically upward and is located directly below the connecting block 120. The output shaft of the motor 117 is fixedly installed with a clamping block 107 through a coupling. The top end of the clamping block 107 is embedded in the clamping groove 121 in the connecting block 120, and the lower end of the clamping block 107 is seamlessly rotatably installed on the top end of the waterproof box 118. The motor 117 is connected to an external power supply through a wire.
[0030] It is further explained that when the temperature of the microbial liquid culture solution is uneven during cultivation and fermentation in the inner shell 114, or when the water is heated by the heater 109, the water temperature in the barrel-shaped temperature control chamber 108 is unevenly distributed, the circuit in the connected motor 117 can be connected, and the output shaft of the motor 117 will drive the inner shell 114 to rotate in the inner layer 104 of the outer shell through the interlocking block 107 and the connecting block 120. The rotating inner shell 114 is used to simultaneously stir the microbial liquid culture solution and water in the inner and outer circles, so that the microbial liquid culture solution and water in the inner and outer circles are heated evenly, and can also better perform heat exchange on both sides of the inner shell 114, cooling or heating.
[0031] In this embodiment, a drain pipe 111 is fixedly installed on the lower bottom surface of the outer shell layer 101, the middle shell layer 103 and the inner shell layer 104. The inner cavity of the drain pipe 111 and the barrel-shaped temperature adjustment chamber 108 are interconnected. The water outlet of the drain pipe 111 is fixedly connected to a water valve 110. The upper ends of the outer shell layer 101, the middle shell layer 103 and the inner shell layer 104 are fixedly installed with a water inlet pipe 113. The inner cavity of the water inlet pipe 113 is also interconnected with the barrel-shaped temperature adjustment chamber 108. The water inlet of the water inlet pipe 113 is fixedly installed with a water valve 2 112. The sizes of water valve 110 and water valve 2 112 are the same.
[0032] It should be noted again that during the fermentation process, the temperature inside the inner shell 114 may rise due to the heat generated by the metabolism of the yeast. When the temperature inside the inner shell 114 exceeds the preset temperature, the water inlet of the water valve 2 112 can be connected to the external tap water faucet through a conduit, and the water valve 1 10 and the water valve 2 112 can be opened to allow the relatively low temperature tap water to flow through the outer wall of the inner shell 114 to lower the temperature inside the inner shell 114. Because the barrel-shaped temperature control chamber 108 can only have water entering through the water inlet pipe 113, the temperature distribution inside the barrel-shaped temperature control chamber 108 is uneven. It is necessary to start the motor 117 while using tap water to cool the water, stir the water in the barrel-shaped temperature control chamber 108, and evenly distribute the heat in the water in the barrel-shaped temperature control chamber 108.
[0033] The utility model can help reduce the heat loss inside the fermentation tank body 1 by using the shell middle layer 103 made of thermal insulation material, thereby effectively maintaining the temperature inside the fermentation tank body 1 stable, which is particularly important for a long fermentation process to prevent temperature fluctuations from affecting the fermentation;
[0034] In winter or in a low-temperature environment, when the temperature inside the fermentation tank body 1 needs to be increased, the water in the barrel-shaped temperature-regulating chamber 108 can be heated by connecting the circuit in the water heater 109. The heated water provides additional heat to the microbial liquid culture liquid inside through the inner shell 114 to maintain the required fermentation temperature, thereby realizing temperature control inside the fermentation tank body through its own equipment.
[0035] When the temperature inside the fermentation tank body 1 exceeds the preset temperature, the water inlet of the water valve 2 112 can be connected to the external tap water through the conduit, and the water valve 110 and the water valve 2 112 are opened to allow the relatively low temperature tap water to flow through the outer wall of the inner shell 114 to reduce the temperature inside the inner shell 114;
[0036] When the temperature of the microbial liquid culture solution during cultivation and fermentation in the inner shell 114 is uneven, or when the water is heated by the heater 109 and the water temperature in the barrel-shaped temperature control chamber 108 is unevenly distributed, the circuit in the connected motor 117 can be connected, and the output shaft of the motor 117 will drive the inner shell 114 to rotate in the inner layer 104 of the outer shell through the interlocking block 107 and the connecting block 120. The rotating inner shell 114 is used to simultaneously stir the microbial liquid culture solution and water in the inner and outer circles, so that the microbial liquid culture solution and water in the inner and outer circles are heated evenly, and the heat exchange on both sides of the inner shell 114 can be better performed.
[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
