Description

Technical Field

[0001] This utility model belongs to the field of constant temperature chambers for oligomannose cultivation, specifically a constant temperature chamber for oligomannose cultivation. Background Technology

[0002] Oligomannose is a functional oligosaccharide belonging to the prebiotic category. It is a type of sugar composed of several mannose molecules linked by glycosidic bonds. It has the functions of regulating intestinal flora and enhancing immunity, and is widely used as a functional food additive.

[0003] In the preparation of oligomannose, microbial culture or enzymatic hydrolysis requires a constant temperature environment. Therefore, constant temperature incubators are often used to provide stable growth or catalytic conditions for bioactive substances. Constant temperature incubators mainly achieve precise control and uniform distribution of temperature inside the chamber through the synergistic effect of temperature control system, heating method and heat preservation structure, thereby meeting the cultivation needs of microorganisms. During the cultivation process, the heat generated by microbial metabolism needs to be discharged in time, otherwise it will lead to increased pressure inside the chamber and cause temperature runaway. Traditional constant temperature incubators usually directly discharge the air inside the chamber to maintain the pressure inside the chamber, but direct discharge will cause a lot of heat energy waste.

[0004] In summary, this invention provides a constant temperature chamber for culturing oligomannose to solve the above problems. Utility Model Content

[0022] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0023] Example 1

[0024] like Figure 1-5The first embodiment of this utility model is shown, which provides a constant temperature chamber for culturing oligomannose, including a constant temperature chamber assembly 100, including a chamber body 110, an inner liner 120 fixed to the upper layer of the inner cavity of the chamber body 110, a pipe fan 140 fixed to one side of the inner liner 120, an air intake assembly 200, including an air intake box 210 fixed to the lower layer of the inner cavity of the chamber body 110, an air intake fan 220 located on one side of the air intake box 210, an air intake pipe 230 located at the top of the air intake box 210, and a filter screen 240 located in the inner cavity of the air intake box 210, a heating assembly 300, including a heating box 310, and an electric heater 320 fixed in the inner cavity of the heating box 310, a recovery assembly 400, including a recovery box 410, a conical hopper 420 connected to the bottom of the recovery box 410, and a centrifugal fan 430 located in the inner cavity of the recovery box 410, and a temperature control assembly 500 for temperature regulation.

[0025] like Figure 1-5 As shown, the air intake assembly 200 purifies the incoming air through a filter 240 to prevent pollution. The filter 240 can be a HEPA filter, which can remove fine particles from the air. Simultaneously, the air intake fan 220 controls the air intake rate to ensure stable airflow. The heating assembly 300 uses an electric heater 320 to heat not only the incoming air but also the recirculated air to maintain the set temperature. The heat recovery assembly 400 uses a centrifugal fan 430 to draw air from inside the inner tank 120 into the heat recovery box 410 and then returns it to the heating box 310 for reheating, achieving heat energy recovery and reuse. The hot air in the inner tank 120 enters the heat recovery box 410. At 0 o'clock, due to the error between the recycling box 410 and the inner tank 120, hot air will condense. At this time, the condensate falls into the conical hopper 420 under the action of gravity. The bottom of the conical hopper 420 is equipped with a drain valve. The conical hopper 420 can also be connected to the water tank of an external humidifier so that the condensate can be recycled. When the humidity in the inner tank 120 is too high, the exhaust can be accelerated by turning on the duct fan 140. Through the integrated coordination of air intake, heating, recycling and temperature control, it can effectively solve the problems of pressure rise caused by heat generated by microbial metabolism and heat energy waste caused by direct exhaust of traditional constant temperature chambers while maintaining a constant temperature environment.

[0026] Example 2

[0027] Reference Figure 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0028] In this embodiment, the box body 110 also includes a box door 130 and a tray frame 150 fixed to both sides of the inner cavity of the inner liner 120. The box door 130 is hinged to the box body 110 by a hinge. The duct fan 140 is connected to the inner cavity of the inner liner 120, and the outlet of the duct fan 140 is connected to the outside of the box body 110.

[0029] The air inlet of the air intake fan 220 is connected to the inner cavity of the air intake box 210. The filter screen 240 is fixed to the inner wall of the air intake box 210 by bolts. One end of the air intake pipe 230 is connected to the air outlet of the air intake box 210, and the other end of the air intake pipe 230 is connected to the air inlet of the heating box 310.

[0030] The heating box 310 is fixed to the top of the recycling box 410, and the air outlet of the heating box 310 is connected to the inner cavity of the inner liner 120.

[0031] The recycling box 410 is fixed to the upper layer of the inner cavity of the box body 110 and is located on the back of the inner liner 120. The air inlet of the recycling box 410 is connected to the inner cavity of the inner liner 120. The centrifugal fan 430 is fixed to the inner cavity of the recycling box 410 and the air outlet of the centrifugal fan 430 is connected to the inner cavity of the heating box 310.

[0032] like Figure 1-5 As shown, the inner liner 120 provides the culture space, and the tray rack 150 is used to support and place the culture containers. The inner liner 120 can be sealed through the door 130 for easy operation and observation. The air intake fan 220 provides airflow power, delivering fresh outside air to the air intake box 210. After being purified by the filter screen 240, the air is delivered to the heating box 310 through the air intake pipe 230. In the heating box 310, the air is heated by the electric heater 320. The heated air then enters the inner liner 120 to maintain the temperature of the oligomannose culture. The centrifugal fan 430 is used in the recovery box 4. The high-speed rotation of the inner chamber 10 generates suction, drawing in hot air from the inner chamber 120 through the air inlet and sending it into the heating chamber 310 for secondary heating before it enters the inner chamber 120 again, thus achieving recycling. Some of the exhaust gas is discharged outside the chamber 110 through the duct fan 140, thereby maintaining the pressure balance inside the inner chamber 120. The duct fan 140 can also assist in exhaust, cooling and dehumidification during the constant temperature incubation process. Through closed-loop circulation and controllable exhaust, efficient utilization of heat is achieved, while maintaining stable air pressure inside the inner chamber 120, effectively preventing temperature runaway and heat waste.

[0033] Example 3

[0034] Reference Figure 1-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0035] In this embodiment,

[0036] The temperature control assembly 500 includes a PID controller 510 fixed to one side of the front of the housing 110, a thermocouple 520 fixed to the heating chamber 310 and the inner cavity of the inner liner 120 for temperature monitoring, a humidity sensor 530 fixed to the inner cavity of the inner liner 120, and a temperature sensor 540 fixed to the surface of the air inlet pipe 230 for air inlet temperature detection.

[0037] The outputs of thermocouple 520, humidity sensor 530 and temperature sensor 540 are all connected to the input of PID controller 510. The output of PID controller 510 is connected to air intake fan 220, electric heater 320, centrifugal fan 430 and duct fan 140 respectively.

[0038] like Figure 1-5 As shown, the PID controller 510 can precisely regulate the working status of the intake fan 220, electric heater 320, centrifugal fan 430, and duct fan 140 based on real-time monitoring data from the thermocouple 520, humidity sensor 530, and temperature sensor 540. When the temperature inside the inner chamber 120 is lower than the set value, the PID controller 510 will increase the power of the electric heater 320 and increase the speed of the intake fan 220 to increase the air intake and heating efficiency. When the temperature is higher than the set value, the PID controller 510 will reduce the power of the electric heater 320 and start the duct fan 140 to assist in exhaust cooling. The monitoring data from the humidity sensor 530 is used to control the starting timing of the duct fan 140 to avoid excessive humidity inside the inner chamber 120 affecting the cultivation effect. When the humidity is higher than the set value, exhaust is carried out through the duct fan 140 to accelerate the discharge of moisture. In addition, the monitoring data from the temperature sensor 540 can ensure that the air temperature entering the heating chamber 310 is suitable, avoiding excessive burden on the heating components 300.

[0039] In operation, the required temperature and humidity range are first set using the PID controller 510. Upon startup, the intake fan 220 draws in outside air into the intake box 210. After being purified by the filter 240, the air is delivered to the heating chamber 310 via the intake pipe 230. The electric heater 320 heats the air, which then enters the inner chamber 120 to provide a constant temperature environment for the oligomannose culture. Simultaneously, the centrifugal fan 430 rotates at high speed within the recovery box 410, drawing in the hot air from the inner chamber 120 and returning it to the heating chamber 310 for secondary heating, thus achieving heat recovery. The PID controller 510, based on real-time monitoring data from thermocouple 520, humidity sensor 530, and temperature sensor 540, precisely regulates the operating status of the intake fan 220, electric heater 320, centrifugal fan 430, and duct fan 140 to ensure that the temperature inside the inner chamber 120 is maintained within the set range. This not only achieves constant temperature culture of oligomannose culture but also effectively solves the problems of increased pressure caused by heat generated by microbial metabolism and heat waste caused by direct exhaust in traditional constant temperature chambers, thus effectively improving heat utilization and culture efficiency.
