Description

Technical Field

[0001] The utility model belongs to the technical field of protease fermentation, and in particular relates to an alkaline protease fermentation tank. Background Art

[0002] Protease is a general term for a class of enzymes that hydrolyze protein peptide chains. According to the way they degrade polypeptides, they are divided into two categories: endopeptidases and terminal peptidases. The former can cut the macromolecular polypeptide chain from the middle to form smaller molecular weight proteins and peptidases; the latter can be divided into carboxyl terminal peptidases and amino terminal peptidases, which hydrolyze the polypeptide chain one by one from the free carboxyl end or free amino end of the polypeptide to generate amino acids.

[0003] The Chinese patent with application number CN202220123202.5 in the prior art discloses a fermentation tank for producing microbial protease, including a fermentation tank, the upper outer surface of the fermentation tank is provided with a stirring motor, and the outer wall of the fermentation tank is provided with a water cooling mechanism. The fermentation tank for producing microbial protease described in the utility model, through the water cooling mechanism provided, when the fermentation tank must be cooled, water is first put into a water cooling box, and then the water pump is turned on, and the water pump conveys the cooling water inside the water cooling box to the inside of the cooling jacket through the water inlet pipe through the first water inlet, and the cooling jacket is made of copper with excellent thermal conductivity. The heat of the fermentation tank is transferred to the cooling jacket, and then absorbed by the cooling water inside the cooling jacket, and at the same time, under the action of the water pump, the cooling water is conveyed to the water cooling box through the water outlet through the water outlet pipe for cooling, and this reciprocates, that is, the cooling of the fermentation tank is realized, and the practicality of the water cooling mechanism is high, which indirectly saves manpower and brings better prospects for use.

[0004] Fermentation tanks often need to be cleaned after use. During the use of the fermentation tank, the protease generates high heat during the fermentation process, causing the fermentation tank body to overheat, which is inconvenient for subsequent people to clean. If it is not cleaned thoroughly, the residual acid protease will affect the next production, resulting in a decrease in the quality of the next product. Utility Model Content

[0026] An alkaline protease fermentation tank comprises an outer shell 1, wherein a feed port 2 is arranged on the upper side of the outer shell 1, a discharge port 3 is arranged near the bottom of the outer shell 1, both ends of the outer shell 1 are rotatably connected with an axial tube 6, a spiral tube 5 is fixedly connected between the two axial tubes 6, a hollow frame 11 is rotatably arranged in the outer shell 1, a rubber eraser 12 is fixedly connected to the hollow frame 11 near the inner wall of the outer shell 1, and a first rotating mechanism and a second rotating mechanism are arranged on the outer shell 1.

[0027] In a specific embodiment of the utility model, the feed port 2 is used to add raw materials into the outer shell 1, and the discharge port 3 is used to discharge the fermented product. The two axial tubes 6 are concentric structures. The spiral tube 5 can rotate in the outer shell 1 based on the axial tube 6. The axial tube 6 is used to connect the external heat exchange pipeline. By circulating the heat exchange liquid into the spiral tube 5, the heat generated by fermentation can be reduced, the fermentation can be kept at the optimal temperature, the fermentation effect can be improved, and the raw materials can be reduced from adhering to the inner wall of the outer shell 1. The hollow frame 11 is used to install the rubber eraser 12, and the rubber eraser 12 is attached to the inner wall of the outer shell 1. During fermentation, the rubber eraser 12 is in a stopped state. When the inner shell 1 needs to be cleaned, the pinion 14 is driven to rotate by the output end of the second motor 13, and the pinion 14 drives the inner gear 15 to rotate, thereby driving the hollow frame 11 to rotate as a whole. The rubber eraser 12 continuously scrapes the inner wall of the outer shell 1, effectively cleaning the residue, and the automatic cleaning is convenient to operate.

[0028] Specifically, the first rotating mechanism includes a first motor 9, a second synchronous wheel 10, a first synchronous wheel 7 and a synchronous belt 8. The first motor 9 is fixedly connected to one end of the housing 1, the first synchronous wheel 7 is fixedly connected to the circumferential surface of the shaft tube 6 close to the first motor 9, the second synchronous wheel 10 is fixedly connected to the output end of the first motor 9, and the synchronous belt 8 is transmission-connected between the second synchronous wheel 10 and the first synchronous wheel 7.

When in use, the second synchronous wheel 10 is driven to rotate by the output end of the first motor 9, and the first synchronous wheel 7 is driven to rotate under the synchronization action of the synchronous belt 8. The first synchronous wheel 7 drives the axial tube 6 to rotate, and finally drives the spiral tube 5 to rotate, so that the spiral tube 5 continuously stirs the raw materials in the outer shell 1, which can provide a stirring and mixing effect. At the same time, by circulating the heat exchange liquid into the spiral tube 5, the heat generated by fermentation is reduced, the fermentation is kept at the optimal temperature, and the fermentation effect is improved.

When the inside of the outer shell 1 needs to be cleaned, the pinion 14 is driven to rotate by the output end of the second motor 13, and the pinion 14 drives the inner gear 15 to rotate, thereby driving the hollow frame 11 to rotate as a whole. The rubber eraser 12 continuously scrapes the inner wall of the outer shell 1 to effectively clean the residue, and the automatic cleaning is convenient to operate.

[0032] Specifically, a thermometer 4 is disposed on the side of the housing 1 .

[0035] In a specific embodiment of the present invention, the feed port 2 is in an open state when adding raw materials, and the discharge port 3 is in an open state when discharging raw materials or sewage.

[0036] Working principle: by circulating the heat exchange liquid into the spiral tube 5, the heat generated by fermentation is reduced, the fermentation is kept at the optimum temperature, the fermentation effect is improved, and the raw materials can be reduced from adhering to the inner wall of the shell 1. The hollow frame 11 is used to install the rubber eraser 12, and the rubber eraser 12 is attached to the inner wall of the shell 1. During fermentation, the rubber eraser 12 is in a stopped state. When it is necessary to clean the inside of the shell 1, the output end of the second motor 13 drives the pinion 14 to rotate, and the pinion 14 drives the inner gear 15 to rotate, thereby driving the hollow frame 11 to rotate as a whole. The rubber eraser 12 continuously scrapes the inner wall of the shell 1 to effectively clean the residue, and the automatic cleaning is convenient to operate.
