Description

Technical Field

[0001] The present invention relates to the technical field of microorganism cultivation, in particular to a microorganism cultivation device for cheese preparation. Background Art

[0002] Cheese is a fermented dairy product that is classified into super-hard cheese, hard cheese, semi-hard cheese, and soft cheese based on factors such as fat content, water content, production process, maturity, and storage conditions. Microorganisms need to be added for fermentation during cheese making. Microbial culture refers to the use of artificially prepared culture media and artificially created culture conditions to allow certain (species) of microorganisms to grow and reproduce rapidly. This is called microbial culture. Microbial culture requires culture medium, which is prepared according to the different types and living habits of microorganisms. The key to successful microbial culture lies in aseptic operation. If the culture equipment and culture medium cannot be thoroughly sterilized, or if there is contamination by miscellaneous bacteria during the culture process, it is easy to fail.

[0003] Most of the existing microbial culture devices for cheese preparation are unable to prepare culture medium liquid. Bacteria need to be added to the prepared culture medium liquid manually. Manual participation can easily affect the sterile environment of culture. In addition, steam sterilization is mostly used during preparation. The steam is usually discharged directly after sterilization, which makes it impossible to effectively utilize energy and causes a certain degree of energy waste. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid blurring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0005] The present invention is proposed in view of the above-mentioned problems and / or problems existing in the existing microbial culture devices for cheese preparation.

[0006] Therefore, the purpose of the present invention is to provide a microbial culture device for cheese preparation. During use, the steam generator generates steam, and the steam converts steam energy into kinetic energy when passing through the driving component. The driving component drives the infusion component to extract the external culture medium liquid into the water tank. At the same time, the steam enters the interior of the shell from the steam inlet, and the culture medium liquid in the water tank and the water tank are simultaneously sterilized at high temperature. The steam is discharged from one side of the shell to the condenser to condense into liquid, and flows back to the steam generator through the first water pipe for recycling. The first fixed frame rises due to buoyancy as the culture medium liquid in the water tank increases under the action of the float. When the first fixed frame rises, it drives the first unloading component to perform intermittent unloading, and the raw materials required for preparing the culture medium liquid are transported to the water tank. The difficult-to-dissolve components in the raw materials can be dissolved more effectively under the action of steam heating. At the same time, the driving component drives the stirring component to stir and mix the culture medium liquid and the raw materials in the water tank. When the first fixed frame rises to the highest water level, the first feeding component respectively carries the valve component to close the steam inlet and open the entrance of the cooling component. The steam changes its path and enters the cooling component to quickly cool the culture medium liquid using the vacuum cooling principle. At the same time, the cooling component drives the second feeding component to transport the culture medium liquid to the cooled culture medium liquid. The second feeding component continues to drive the stirring component to stir and mix the culture medium liquid and the culture medium liquid. The steam passes through the cooling component into the condenser and is still condensed into liquid and then flows back to the steam generator for reuse.

[0059] Specifically, the steam generator 3 generates steam, and the steam enters the first sealed shell 5 through the first steam pipe 4, driving the first steam turbine 74 to rotate. The first steam turbine 74 drives the impeller 75 and the ratchet 66 to rotate respectively. The impeller 75 draws the external culture medium liquid into the water storage tank 35. At the same time, the steam sterilizes the water storage tank 35 and the culture medium liquid at high temperature. The steam enters the condenser 23 from the exhaust port and is condensed into liquid. It flows back to the steam generator 3 through the first water pipe 11 for recycling. The first fixed frame 37 rises as the culture medium liquid increases, and the screw 34 is driven to rotate by the cooperation of the internal threaded through hole and the screw 34. At the same time, the turntable 30 is driven to rotate intermittently by the cooperation of the cam 39 and the groove wheel 51, so that the raw material dish 31 revolves along the circular guide rail 30. When the raw material dish 3 When the first discharge port 32 at the bottom coincides with the input end of the first discharge pipe 54, the raw materials fall into the water storage tank 35 under the action of gravity.

The tearing force of the curved stirring rod 62 relative to the driving stirring blade is small, and it is not easy to damage the molecular structure of the microorganisms. The reciprocating screw 65 drives the flap 63 to move up and down along the limit rod 48 to flip the stirring base liquid. , to a certain extent, it makes up for the problem that the curved stirring rod 62 has a poor stirring effect due to its small size. At the same time, the screw 34 drives the third gear 26 to rotate, and the first valve is slowly closed through the cooperation of the third gear 26 and the reduction gear 25. When the first fixing frame 37 rises to the highest point, the first valve is completely closed, and the second valve is opened under the cooperation of the local gear 27 and the fourth gear 29. The steam enters the second sealed shell 14 from the third steam pipe 13 to drive the second steam turbine to rotate, and then enters the tapered tube 20 from the second sealed shell 14. The flow rate of steam in the tapered tube 20 increases, and the air in the shell 1 is extracted through the air pipe 21, so that a relative vacuum state is formed inside the shell 1. The boiling point of the culture medium liquid is reduced in the vacuum environment, and it boils to dissipate heat and cool down. The second steam turbine drives The worm 15 rotates, and the cooperation between the worm 15 and the worm wheel 16 drives the second pulley 17 to rotate. Under the action of the first transmission belt 71, the conveying wheel 72 is driven to rotate, and the bacterial strain is conveyed from the second discharge port 73 to the water storage tank 35. Under the action of the second transmission belt 19, the third bevel gear 42 drives the fourth bevel gear 58 to rotate, allowing the curved stirring rod 62 to continue stirring to fully mix the cooled culture medium liquid with the bacterial strain. Under the action of the spring 69, the ratchet 66 is disengaged from the ratchet ring 46 to prevent the first steam turbine 74 from idling and causing damage. The steam enters the condenser 23 from the fourth steam pipe 22 and is still condensed into liquid before flowing back to the steam generator 3 for reuse, solving the problem that most existing microbial culture devices for cheese preparation cannot prepare culture medium liquid.The bacteria need to be added to the prepared culture medium manually, which can easily affect the sterile environment of the culture. In addition, steam sterilization is mostly used during preparation. The steam is usually discharged directly after sterilization, which makes it impossible to effectively utilize energy and causes a certain degree of energy waste.

In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
