[0001] This utility model relates to the field of microbial fermentation technology, specifically to a constant temperature heating microbial fermentation device. Background Technology

[0002] Heated microbial fermentation equipment is a device that provides the optimal growth environment for microorganisms through a precise temperature control system. It uses heating modules and heat exchange structures to maintain a constant temperature, ensuring the activity and metabolic efficiency of the microorganisms. It is widely used in the food, pharmaceutical and scientific research fields and features uniform temperature, precise control and easy operation.

[0003] In the fermentation process of probiotic strains, sampling is a key step in monitoring the fermentation process and ensuring product quality. In existing technologies, a feeding port is usually opened on the upper surface of the fermentation container. Sampling can only be carried out after the feeding port is opened. Since the feeding port is far from the liquid surface of the material, it is inconvenient to sample the material. Moreover, the feeding port is kept open for too long, which can easily lead to contamination of the material in the fermentation container. To address these issues, a constant temperature heating fermentation device is proposed. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions: A constant temperature heating type microbial fermentation device includes a fermentation tank, and multiple sampling mechanisms are arranged below the fermentation tank. The fermentation tank includes a servo motor. The sampling mechanism includes a sealing tube, with a sealing ring pasted on the middle of the inner wall of the sealing tube; and a sampling tube is slidably and through the middle of the inner wall of the sealing tube, with a baffle fixedly connected to the top of the sampling tube, the bottom surface of the baffle abutting against the top of the sealing tube. The sampling tube has a sampling port at the upper end of its outer wall, and a block is slidably connected to the inner wall of the sampling tube near the sampling port. A pull rod is fixedly connected to the middle of the bottom surface of the block, and the bottom end of the pull rod extends to the bottom of the sampling tube. The sampling tube has an end plate fixedly connected to the lower end of its outer wall, and a bolt is threaded through the side of the end plate. The upper end of the bolt is threaded to the bottom surface of the sealing tube.

[0005] As a further embodiment of this utility model: an extension rod is fixedly connected to the bottom surface of the baffle and to both sides of the sampling tube, a limit block is fixedly connected to the bottom end of each extension rod, and a reset spring is fixedly connected to the bottom of each limit block, with the bottom end of the reset spring fixedly connected to the inner wall of the sealing tube.

[0006] As a further embodiment of this utility model: the extension rod and the sealing tube are aligned in the length direction, the top surface of the limiting block abuts against the inner wall of the sealing tube, and the side of the limiting block is slidably connected along the inner wall of the sealing tube.

[0007] As a further embodiment of this utility model: the fermenter includes a tank body, the top of the tank body is sealed with a top cover, and the outside of the top cover is sealed with a feeding door.

[0008] As a further embodiment of this utility model: a discharge pipe is fixedly and continuously connected to one end of the bottom surface of the tank body, and a valve is fixedly installed on the outer wall of the discharge pipe. The bottom surface of the tank body is connected to each sealing pipe through and fixedly connected.

[0009] As a further embodiment of this utility model: the top center of the top cover is fixedly connected to a servo motor, the output shaft of the servo motor extends into the inside of the top cover, and a stirring rod is fixedly connected to the output shaft of the servo motor.

[0010] As a further embodiment of this utility model: a heat exchange circulation pipe is embedded and fixedly fixed on the inner wall of the tank body, both ends of the heat exchange circulation pipe extend to the outside of the tank body, and both ends of the heat exchange circulation pipe are provided with interfaces.

[0011] The beneficial effects of this utility model are: (1) This utility model has multiple sampling mechanisms at the bottom of the fermentation tank. When it is necessary to sample the material, the material can be led out to the outside of the fermentation tank through the sampling tube by pulling down the lever, thereby reducing the difficulty of material sampling. (2) The sampling mechanism is fixed to the bottom of the fermenter by a sealing tube. When sampling is not required, the sealing tube can be closed with the baffle above to prevent material leakage. In addition, when no sampling is performed, the block moves up to the sampling port to seal it, which further improves the sealing performance of the sampling mechanism and prevents the material in the fermenter from being contaminated. (3) The inner wall of the fermentation tank is inlaid with a spiral heat exchange circulation pipe. Liquid or gaseous media can flow in the heat exchange circulation pipe and the heat is conducted to the material inside the tank through a copper heat conduction block, which facilitates the heating of the material.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1-6 As shown, a constant-temperature heating fermentation device includes a fermenter 1, with multiple sampling mechanisms 2 arranged below the fermenter 1. The fermenter 1 includes a servo motor 106. Each sampling mechanism 2 includes a sealing tube 201, with a sealing ring affixed to the middle of its inner wall. A sampling tube 202 is also slidably connected and penetrates the middle of the inner wall of the sealing tube 201. A baffle 203 is fixedly connected to the top of the sampling tube 202, with the bottom surface of the baffle 203 abutting against the top of the sealing tube 201. The sampling mechanism 2... A sampling port 207 is provided at the upper end of the outer wall of the sampling tube 202. A plug 208 is slidably connected to the inner wall of the sampling tube 202 near the sampling port 207. A pull rod 209 is fixedly connected to the middle of the bottom surface of the plug 208, and the bottom end of the pull rod 209 extends to the bottom of the sampling tube 202. An end plate 210 is fixedly connected to the lower end of the outer wall of the sampling tube 202. A bolt 211 is threaded through the side of the end plate 210. The upper end of the bolt 211 is threaded to the bottom surface of the sealing tube 201. Figure 5 As shown, with the support of bolt 211, sampling tube 202 is raised, and sampling port 207 is located above sealing tube 201. An extension rod 204 is fixedly connected to the bottom surface of the baffle 203 on both sides of the sampling tube 202. A limit block 205 is fixedly connected to the bottom end of each extension rod 204. A return spring 206 is fixedly connected to the bottom of each limit block 205. The bottom end of the return spring 206 is fixedly connected to the inner wall of the sealing tube 201. Figure 5 As shown, the outer side of the return spring 206 is wrapped with a rubber sleeve to prevent excessive moisture from corroding the metal material and to improve the stability of the spring structure. In addition, the return spring 206 has a large elastic coefficient, which ensures that the return spring 206 can overcome the sliding friction between the inner wall of the sampling tube 202 and the sealing tube 201 when it retracts and resets. The extension rod 204 is aligned with the sealing tube 201 in the length direction, and the top surface of the limiting block 205 abuts against the inner wall of the sealing tube 201. Furthermore, the side of the limiting block 205 is slidably connected along the inner wall of the sealing tube 201. Figure 5 As shown, the limiting block 205 prevents the extension rod 204 from completely disengaging; Fermentation tank 1 includes a tank body 101, a top cover 102 that is sealed to the top of the tank body 101, and a feeding door 103 that is sealed to the outside of the top cover 102. Figure 3 As shown, the top cover 102 and the tank body 101, and the feeding door 103 and the top cover 102 can all be sealed and fixed by fasteners such as screws; A discharge pipe 104 is fixedly and continuously connected to one end of the bottom surface of the tank body 101. A valve 105 is also fixedly installed on the outer wall of the discharge pipe 104. The bottom surface of the tank body 101 is connected to each sealing pipe 201 through and fixedly connected. Figure 1 As shown, after opening valve 105, the material can be discharged through discharge pipe 104; The top center of the top cover 102 is fixedly connected to the servo motor 106. The output shaft of the servo motor 106 extends into the top cover 102, and a stirring rod 107 is fixedly connected to the output shaft of the servo motor 106. A heat exchange circulation pipe 108 is embedded and fixedly fixed on the inner wall of the tank body 101. Both ends of the heat exchange circulation pipe 108 extend to the outside of the tank body 101, and both ends of the heat exchange circulation pipe 108 have an interface 109. Several heat-conducting blocks 110 are fixedly connected to the inner side of the heat exchange circulation pipe 108. The other side of each heat-conducting block 110 extends into the inside of the tank body 101, and the outer wall of the heat-conducting block 110 is embedded and fixedly fixed to the tank body 101. Figure 3 As shown, both the heat exchange circulation tube 108 and the heat conduction block 110 can be made of copper.

[0017] The working principle of this utility model: When the device is in use, the circulating pump for conveying the heating medium is connected to the two ports 109 respectively. The material is injected into the tank body 101 by opening the feeding door 103. The heating medium flows along the heat exchange circulation pipe 108 and transfers heat to the material through the heat conduction block 110. During this period, the servo motor 106 is started and drives the material to rotate through the stirring rod 107, thereby improving the uniformity of heating. When material sampling is required, screwing bolt 211 into the sealing tube 201 causes baffle 203 and sampling tube 202 to rise. Baffle 203 moves upward and separates from sealing tube 201, stretching return spring 206 and exposing sampling port 207. Then, pull rod 209 downward, causing block 208 to fall, allowing material to enter sampling tube 202 through sampling port 207. Afterward, screwing disassembly bolt 211 causes end plate 210 to lose support, releasing elastic potential energy from return spring 206 and pulling limit block 205 downward. Extension rod 204 causes baffle 203 to close with the top of sealing tube 201. Finally, pull rod 209 is pulled down further, causing block 208 to come out from below sampling tube 202, allowing material inside sampling tube 202 to exit from below.

[0018] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
