Description

Technical Field

[0001] This utility model specifically relates to the field of microbial fermentation technology, and more specifically to a seed tank for rapid propagation of yeast strains adapted to the characteristics of yeast. Background Technology

[0002] In the bio-fermentation industry, yeast, as an important microorganism, is widely used in food, beverage, and pharmaceutical industries. In order to meet the needs of large-scale production, it is necessary to rapidly expand yeast strains. Effective control of temperature, humidity, and ventilation during yeast expansion inside the seed tank is essential to ensure the rapid expansion of yeast strains.

[0003] However, traditional seed culture tanks cannot effectively automate the process and still require manual intervention, such as adding materials manually. This can lead to inconsistent temperature control inside the seed tank, affecting yeast growth and resulting in low propagation efficiency.

[0004] A search revealed that Chinese Patent Publication No. CN202121644938.9 discloses a yeast liquid culture device, comprising a main body, a fastening assembly, and a moving assembly. The main body includes a reaction vessel, which is fixedly connected to an end cap via the fastening assembly. A moving assembly is provided on one side of the reaction vessel. The fastening assembly includes a movable rod that passes through the end cap. A limiting plate is sleeved on the surface of the movable rod, and a spring is sleeved on the surface of the movable rod. The limiting plate is fixedly connected to the end cap. A locking block is fixedly connected to one end of the movable rod, and a first slider is fixedly connected to one side of the locking block. The first slider is movably connected to the end cap via a first sliding groove. A handle is fixedly connected to the other end of the movable rod, and a positioning post is fixedly connected to one side of the handle. The positioning post is movably connected to the reaction vessel via a positioning hole. A sealing block is fixedly connected to the lower surface of the end cap.

[0005] While the device in the aforementioned patent can effectively achieve automatic material addition, it cannot effectively regulate the environment during material propagation. As a result, the material in the aforementioned patent can only undergo natural propagation within the reaction vessel. This may lead to slow yeast production and low propagation efficiency due to inaccurate temperature control, uneven ventilation, and unsatisfactory mixing. Consequently, it cannot effectively meet the requirements for yeast propagation and affects subsequent use. Utility Model Content

In this structure, a temperature regulating pipe is provided on the surface of the tank, so that the internal temperature of the tank can be adjusted according to the growth needs of yeast during propagation. Multiple additive ports are provided on the top of the tank to facilitate the addition of microorganisms during yeast propagation. To ensure the growth of yeast, a pH detection and adjustment structure is used to detect the yeast inside the tank during propagation, avoiding uneven growth of yeast caused by uneven pH, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 In this embodiment of the invention, a rapid propagation seed tank for yeast strains adapted to their characteristics includes a tank body 1; a temperature regulating pipe 12 is integrally formed on the outer wall of the tank body 1; a thermometer is installed inside the temperature regulating pipe 12; cooling water outlet 14 and cooling water inlet 16 are respectively provided at both ends of the temperature regulating pipe 12; wherein the cooling water inlet 16 is connected to a steam pipe 10 through a connecting valve; a pH detection and adjustment structure 3 is fixedly installed on the top of the tank body 1, and a feed inlet 2 is provided on one side of the pH detection and adjustment structure 3.

[0029] A pressure regulating pipe 4 is provided on the top side of the tank body 1 away from the feed inlet 2; the pressure regulating pipe 4 is connected to the negative pressure structure;

[0030] The bottom of the tank 1 is designed to be conical with a cone angle of 120°; the bottom of the tank 1 is provided with a discharge port 15; a butterfly valve is installed inside the discharge port 15; and a support leg is fixedly installed at the bottom of the tank 1.

[0031] By adopting the above technical solution, yeast is added through the feed inlet 2 at the top of the tank 1 during use. This effectively controls the amount of yeast added and ensures the quality of the expansion. Microorganisms are automatically added into the tank 1 through the additive inlet 5 to meet the needs of strain expansion.

[0032] The top of the tank 1 is also integrally provided with multiple additive ports 5; the tank 1 is also connected to a compressed gas pipeline 6.

[0033] In this embodiment, a drive motor 11 is fixedly installed on the top of the tank 1 by a support frame 13; the shaft of the drive motor 11 extends into the inside of the tank 1 and is fixedly installed with stirring teeth 17.

[0034] By adopting the above technical solution, during the expansion process, the driving motor 11 drives the stirring teeth 17 to rotate, effectively mixing the yeast and microorganisms thoroughly. The thermometer installed inside the temperature regulating pipe 12 effectively detects the temperature inside the tank 1. Cooling is achieved through the steam pipe 10 and the temperature regulating pipe 12. The temperature inside the tank 1 is raised or lowered by rotating the cooling water inlet 16 and the cooling water outlet 14, meeting the needs of yeast expansion and ensuring the efficiency of expansion.

[0035] In this embodiment, the cooling water outlet 14 is connected to the connecting pipe 9, which is also connected to the wastewater pipe 7 and the steam pipe 10 respectively, wherein the steam pipe 10 is equipped with a regulating valve.

[0036] A circulating water pipe 8 is provided between the wastewater pipe 7 and the connecting pipe 9; the circulating water pipe 8 is connected to the cooling water tank.

[0037] The compressed gas pipeline 6, wastewater pipeline 7, circulating water pipeline 8, connecting pipe 9 and steam pipeline 10 are installed inside the ground, and the tank 1 is installed inside a pit opened on the ground.

[0038] By adopting the above technical solution, the pressure inside tank 1 will change during expansion cultivation. When the pressure inside tank 1 affects expansion cultivation, the pressure inside tank 1 can be depressurized or air exchanged through the pressure regulating pipe 4 to avoid affecting the efficiency of expansion cultivation. When discharging material, the butterfly valve in the discharge port 15 is opened, and the compressed gas pipe 6 is used to pressurize the inside of tank 1, effectively discharging the cultured bacteria inside tank 1 and avoiding residues that affect the efficiency of reuse.

[0039] The working principle of this invention is as follows: During use, yeast is added through the feed inlet 2 at the top of the tank 1, which effectively controls the amount of yeast added and ensures the quality of the culture. Microorganisms are automatically added into the tank 1 through the additive inlet 5 to meet the needs of the culture.

[0040] During the expansion process, the drive motor 11 drives the stirring teeth 17 to rotate, effectively mixing the yeast and microorganisms thoroughly. The thermometer installed inside the temperature regulating pipe 12 effectively detects the temperature inside the tank 1. Cooling is achieved through the steam pipe 10 and the temperature regulating pipe 12. The rotation of the cooling water inlet 16 and the cooling water outlet 14 raises or lowers the temperature inside the tank 1, meeting the needs of yeast expansion and ensuring the efficiency of expansion.

[0041] During the expansion process, the pressure inside tank 1 will change. When the pressure inside tank 1 affects the expansion, the pressure inside tank 1 is depressurized or air is exchanged through the pressure regulating pipe 4 to avoid affecting the expansion efficiency. When discharging material, the butterfly valve in the discharge port 15 is opened, and the compressed gas pipe 6 is used to pressurize the inside of tank 1, effectively discharging the cultured bacteria inside tank 1 and avoiding residues that affect the efficiency of reuse.
