Abstract
Description
Technical Field
[0001] This utility model relates to the field of yeast fermentation broth technology, specifically a device for preserving highly active yeast fermentation broth. Background Technology
[0002] Yeast fermentation broth refers to the mixed liquid formed during yeast fermentation. It has important applications in many fields such as food, beverages, and pharmaceuticals. It is used in the production of fermented dough foods such as bread and steamed buns to make the dough rise and become soft; in the brewing of alcoholic beverages such as beer, wine, and spirits, yeast fermentation broth converts sugars into alcohol and flavor compounds; it can also be used in the production of fermented dairy products, such as yogurt and fermented milk wine, to improve the taste and texture of the products.
[0003] A high-activity preservation device is needed in the production of yeast fermentation broth. Chinese utility model patent CN217526389U discloses a storage device for producing concentrated yeast fermentation broth, including a storage cylinder. A heating cylinder is fitted onto the surface of the storage cylinder, and a heating component is installed inside the heating cylinder. An end cap is located at the top of the storage cylinder. A first stirring element is located at the bottom center of the end cap. Two sets of horizontal plates are fixed to the surface of the first stirring element, and a second stirring element is rotatably connected below each of the horizontal plates. A motor is fixed to the top of the end cap, and a rotating component is located inside the storage cylinder. This utility model, by setting the first and second stirring elements, can uniformly stir the raw materials inside the storage cylinder, thereby improving the uniform heating of the raw materials and increasing the efficiency of the concentrated raw materials. The rotating component further enhances the uniform heating effect of the raw materials.
[0004] However, during the use of this utility model, the device heats the yeast fermentation liquid when storing it, while the yeast fermentation liquid is usually stored in a low-temperature environment, which makes it impossible to guarantee the long-term storage of the yeast fermentation liquid and meet production needs. Therefore, a high-activity yeast fermentation liquid storage device is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a highly active yeast fermentation broth preservation device with the advantage of good preservation effect. It solves the problem that existing preservation devices heat the yeast fermentation broth during preservation, while yeast fermentation broth is usually preserved in a low-temperature environment, thus failing to guarantee the long-term preservation of the yeast fermentation broth.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-activity yeast fermentation broth preservation device, comprising a preservation tank and a sealing cover plate fixedly installed on the top of the preservation tank, wherein an installation box is fixedly installed on the top of the sealing cover plate, and the installation box is provided with a quantitative feeding mechanism capable of quantitatively adding buffer.
[0007] The quantitative feeding mechanism includes a storage tank fixedly installed on the top of the installation box. An electric push rod is fixedly installed inside the installation box. A quantitative cylinder is fixedly connected to the output end of the electric push rod. A movable bottom cover is hinged to the bottom of the quantitative cylinder. A movable plate is fixedly connected to one end of the quantitative cylinder near the storage tank. A communication port connected to the quantitative cylinder is opened on the movable plate.
[0008] Furthermore, the bottom of the storage tank is connected to the inside of the metering cylinder through a connecting port, and the top of the storage tank is fixedly connected to a feeding pipe that is connected to the inside of the cylinder.
[0009] Furthermore, the upper surface of the feeding tube is on the same horizontal plane as the lower surface of the mounting box, and a sealing end cap is installed on the top of the feeding tube.
[0010] Furthermore, the upper surface of the movable plate abuts against the inner top wall of the mounting box, and positioning strips extending into the interior of the mounting box are fixedly connected to both the front and back of the movable plate. Positioning grooves that match the positioning strips are provided on the inner wall of the mounting box.
[0011] Furthermore, a storage liner is fixedly connected inside the storage tank, and a cooling coil is fixedly connected between the storage liner and the storage tank, with a cooling medium inside the cooling coil.
[0012] Furthermore, one end of the cooling coil is fixedly connected to a water inlet pipe extending to the outside of the storage tank, and the other end of the cooling coil away from the water inlet pipe is fixedly connected to a drain pipe.
[0013] Furthermore, the storage tank is externally fixedly connected to three support rods extending to its bottom, and the top of the sealing cover is fixedly connected to a feed pipe communicating with the inside of the storage tank.
[0014] Furthermore, a discharge pipe is fixedly connected to the bottom of the storage tank, and a valve is fixedly installed on the outside of the discharge pipe.
[0015] Compared with the prior art, this utility model provides a highly active yeast fermentation broth preservation device, which has the following beneficial effects:
[0016] 1. This high-activity yeast fermentation broth preservation device uses an electric push rod to move the metering cylinder to the left. When the metering cylinder separates from the mounting box, the movable bottom cover rotates downwards due to gravity. Then, through the feeding pipe, the buffer inside the metering cylinder can enter the preservation tank, thereby stabilizing the pH value of the yeast fermentation broth and improving the preservation effect. At the same time, the reciprocating movement of the metering cylinder can achieve the effect of quantitative feeding.
[0017] 2. This high-activity yeast fermentation broth preservation device, by incorporating a cooling coil, can cool the yeast fermentation broth inside the preservation tank, keeping it in a lower temperature environment. This reduces the metabolic activity of yeast cells, slows down the fermentation process, inhibits the growth and reproduction of microorganisms, and extends the shelf life of the fermentation broth. This solves the problem that existing preservation devices heat the yeast fermentation broth during preservation, which is typically stored at low temperatures, thus failing to guarantee long-term preservation.

[0023] 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.
[0024] Please see Figures 1 to 4This embodiment of a high-activity yeast fermentation broth preservation device includes a preservation tank 1 and a sealing cover 2 fixedly installed on the top of the preservation tank 1. An installation box 3 is fixedly installed on the top of the sealing cover 2. The installation box 3 is equipped with a quantitative feeding mechanism for quantitatively adding buffer. The quantitative feeding mechanism includes a storage tank 4 fixedly installed on the top of the installation box 3. An electric push rod 5 is fixedly installed inside the installation box 3. A quantitative cylinder 6 is fixedly connected to the output end of the electric push rod 5. A movable bottom cover 7 is hinged to the bottom of the quantitative cylinder 6. A movable plate 8 is fixedly connected to one end of the quantitative cylinder 6 near the storage tank 4. A communication port 9 connected to the quantitative cylinder 6 is provided on the movable plate 8.
[0025] Specifically, the bottom of the storage tank 4 is connected to the inside of the metering cylinder 6 through the connecting port 9, and the top of the storage tank 1 is fixedly connected to the feeding pipe 10 which is connected to the inside of the storage tank 1. The upper surface of the feeding pipe 10 is on the same horizontal plane as the lower surface of the mounting box 3, and a sealing end cap is installed on the top of the feeding pipe 10.
[0026] It should be noted that the upper surface of the movable plate 8 abuts against the inner top wall of the mounting box 3, and the front and back of the movable plate 8 are fixedly connected with positioning strips extending into the interior of the mounting box 3. The inner wall of the mounting box 3 is provided with positioning grooves that are compatible with the positioning strips.
[0027] It should be noted that the storage tank 4 is equipped with a buffer, which is a solid powder. When the metering cylinder 6 is separated from the mounting box 3, the solid position on the moving plate 8 will block the opening on the mounting box 3, thereby preventing the buffer inside the storage tank 4 from falling further.
[0028] Please see Figure 2 In this embodiment, a storage liner 11 is fixedly connected inside the storage tank 1, and a cooling coil 12 is fixedly connected between the storage liner 11 and the storage tank 1. A cooling medium is provided inside the cooling coil 12, and a water inlet pipe 13 extending to the outside of the storage tank 1 is fixedly connected to one end of the cooling coil 12, and a drain pipe 14 is fixedly connected to the other end of the cooling coil 12 away from the water inlet pipe 13.
[0029] Specifically, the cooling medium is an ethylene glycol solution, and a temperature sensor is fixedly installed inside the storage liner 11. The temperature sensor is a thermocouple temperature sensor, which can monitor the temperature of the yeast fermentation liquid.
[0030] Please see Figure 1 and Figure 2 In this embodiment, the storage tank 1 is fixedly connected to three support rods 15 extending to its bottom. The top of the sealing cover plate 2 is fixedly connected to a feed pipe 16 that communicates with the inside of the storage tank 1. The bottom of the storage tank 1 is fixedly connected to a discharge pipe 17. A valve 18 is fixedly installed on the outside of the discharge pipe 17. A sealing cover is installed on the top of the feed pipe 16.
[0031] The working principle of the above embodiments is as follows:
[0032] First, the staff pours the buffer into the storage tank 4. Then, the yeast fermentation liquid to be preserved is poured into the storage tank 1 through the feed pipe 16. At this time, the cooling medium is transported to the cooling coil 12 through the water inlet pipe 13. As the cooling medium flows inside the cooling coil 12, it carries away the heat in the yeast fermentation liquid and keeps the yeast fermentation liquid in a low-temperature environment. Then, the staff can start the electric push rod 5 to move the metering cylinder 6 to the left. At this time, the buffer inside the metering cylinder 6 is poured into the storage tank 1, and the feed pipe 10 is sealed.
[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
