Description

Technical Field

[0001] This utility model belongs to the technical field of enzyme fermentation equipment, specifically relating to an equipment for fruit enzyme fermentation. Background Technology

[0002] Fruit enzymes are products made by fermenting fruits. They contain abundant nutrients such as sugars, organic acids, minerals, vitamins, phenols, and terpenes, as well as some important bioactive substances such as enzymes. Fruit enzyme fermentation equipment can be divided into small-scale household equipment and large-scale industrial equipment, depending on the production scale and process requirements.

[0003] For example, in Chinese utility model publication CN217922033U, entitled "Fermentation Equipment for Fruit Enzyme Liquid Production," a fermentation tank is included. The side wall of the tank includes an outer wall and an inner wall, and a phase change material receiving cavity is provided between the outer wall and the inner wall. The phase change material receiving cavity is filled with phase change material. The above-mentioned prior art is easy to operate and use, and easy to disassemble and assemble, which greatly improves the fermentation speed of enzyme liquid and increases the collection volume of enzyme liquid. It can fully ferment fruit pulp and improve the quality of fermentation liquid. However, ventilation is required during the fermentation process to control the oxygen content, material uniformity, and microbial environment in the fermentation system. The air entering needs to be clean to avoid the entry of miscellaneous bacteria that will destroy the microbial community. It is not easy to allow clean air to enter and increase the contact area with the fermentation liquid to improve the efficiency of oxygen dissolution. Therefore, there is a need for a fermentation equipment for fruit enzymes. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed equipment for fruit enzyme fermentation in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A fruit enzyme fermentation device includes a fermentation tank, a top cover fixed to the upper side of the fermentation tank by multiple bolts, a stirring mechanism for stirring the material in the fermentation tank fixedly installed on the top cover, a sterilization air intake mechanism fixedly installed on one side of the top cover, and a vent valve fixedly connected to the upper side of the top cover.

[0007] As a further optimization of this utility model, the sterilization air intake mechanism includes an air pump fixed on the upper side of the top cover, the air pump output port is fixedly connected to a gas flow meter fixed on the top cover, the output end of the gas flow meter is fixedly provided with an air intake pipe connected to the fermentation tank, both ends of the air intake pipe are fixedly provided with ultraviolet sterilization lamps near the gas flow meter, a second filter screen is inserted and engaged on the upper side of the air intake pipe, and a microporous aeration disc located at the bottom of the fermentation tank is fixedly provided on the lower side of the air intake pipe.

[0008] As a further optimization of this utility model, a sealing ring that fits with the top cover is fixedly provided on the upper side of the fermentation tank, and a first filter screen is fixedly provided on the lower inside of the fermentation tank.

[0009] As a further optimization of this utility model, the stirring mechanism includes a servo motor fixed on the upper side of the top cover, and a transmission rod rotating inside the fermentation tank is fixedly installed on the output shaft of the servo motor. Stirring blades are fixedly installed at both ends of the lower side of the transmission rod, and scraper strips that are in contact with the first filter screen are fixedly installed on the lower side of the two stirring blades.

[0010] As a further optimization of this utility model, a connecting plate is fixedly provided on the upper side of the fermentation tank and the lower side of the top cover, and a handle is fixedly provided on both sides of the connecting plate on the top cover.

[0011] As a further optimization of this utility model, a drain pipe is fixedly connected to the lower side of the fermentation tank, and a switch valve is fixedly installed in the middle of the vent valve.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model incorporates a sterilization and air intake mechanism. An air pump draws external air into the fermentation tank, and a gas flow meter connected to the air pump monitors the incoming air flow. Clean air needs to be quantitatively supplied into the fermentation tank. When the gas enters the air intake pipe, it is first sterilized by ultraviolet sterilization lamp irradiation, and then filtered through a second filter to allow clean air to enter. The air is dispersed into tiny bubbles through a microporous aeration disc at the bottom of the air intake pipe, which facilitates the entry of clean air and increases the contact area with the fermentation liquid, thereby improving the efficiency of oxygen dissolution.

[0014] 2. This utility model incorporates a stirring mechanism and a first filter screen. The first filter screen separates the fermented fruit from the drain pipe, allowing the enzyme liquid to be discharged from the drain pipe. During fermentation, a servo motor drives a transmission rod to rotate, causing the stirring blades to stir the fruit and microbial cells, ensuring thorough mixing of the materials with the fermentation liquid. This prevents excessively high or low sugar concentrations in certain areas and ensures a consistent microbial metabolic environment across all regions. The scraper moves the material on the first filter screen, preventing material accumulation and clogging of the first filter screen. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, a fruit enzyme fermentation device includes a fermentation tank 1. A top cover 2 is fixed to the upper side of the fermentation tank 1 by multiple bolts. A sealing ring 5 is fixed to the upper side of the fermentation tank 1, and the sealing ring 5 fits against the top cover 2. When the fermentation tank 1 and the top cover 2 are connected, the sealing ring 5 seals the connection between the two to prevent bacteria from entering the fermentation tank 1. A connecting plate 3 is fixed to the upper side of the fermentation tank 1, and a connecting plate 3 is also fixed to the lower side of the top cover 2. A handle 4 is fixed to the top cover 2. Multiple bolts pass through the two connecting plates 3 to fix the fermentation tank 1 and the top cover 2 together. When removing the top cover 2 from the fermentation tank 1, the user holds the handle 4 to easily remove the top cover 2 along with the structure fixed to it. A control panel is fixed to one side of the fermentation tank 1 to control the electrical components on the fermentation device.

[0025] like Figure 3 , Figure 4As shown, a stirring mechanism 6 is fixedly installed on the top cover 2. The stirring mechanism 6 stirs the material in the fermentation tank 1. The stirring mechanism 6 includes a servo motor 601, which is fixed on the upper side of the top cover 2. A transmission rod 602 is fixedly installed on the output shaft of the servo motor 601. The transmission rod 602 rotates inside the fermentation tank 1. Stirring blades 603 are fixedly installed at both ends of the lower side of the transmission rod 602. A scraper 604 is fixedly installed on the lower side of the two stirring blades 603. A first filter screen 7 is fixedly installed on the lower side of the inside of the fermentation tank 1. The scraper 604 is in contact with the first filter screen 7. When it is necessary to stir the material in the fermentation tank 1, the servo motor 601 is started. The servo motor 601 drives the transmission rod 602 to rotate. The transmission rod 602 carries the stirring blades 603 to stir the material. When rotating, the scraper 604 pushes the material on the upper side of the first filter screen 7 to move, preventing the material from accumulating on the first filter screen 7.

[0026] like Figure 5 , Figure 6 As shown, a sterilization air intake mechanism 8 is fixedly installed on one side of the top cover 2. The sterilization air intake mechanism 8 includes an air pump 801, which is fixed on the upper side of the top cover 2. The air pump 801 delivers external air into the fermentation tank 1. The output port of the air pump 801 is fixedly connected to a gas flow meter 802. An air inlet pipe 803 is fixedly installed at the output end of the gas flow meter 802. The lower side of the air inlet pipe 803 is close to the lower side of the inside of the fermentation tank 1. The gas flow meter 802 calculates the flow rate of the air flowing in the air inlet pipe 803 and can control the amount of air entering the fermentation tank 1. An ultraviolet sterilization lamp 804 is fixedly installed in the air inlet pipe 803. The ultraviolet sterilization lamp 804 is located on the side close to the gas flow meter 802 and enters the fermentation tank 1. The air needs to be kept clean. The ultraviolet germicidal lamp 804 sterilizes the air entering the air inlet pipe 803 by ultraviolet irradiation, preventing bacteria from entering the fermentation tank 1. A second filter 805 runs through the upper side of the air inlet pipe 803. The second filter 805 filters the sterilized air, allowing clean air to enter the fermentation tank 1. The second filter 805 can be pulled out from the upper side of the air inlet pipe 803 for cleaning or replacement. A microporous aeration disc 806 is fixedly installed on the lower side of the air inlet pipe 803. The microporous aeration disc 806 is located at the bottom of the fermentation tank 1. The microporous aeration disc 806 disperses the air into tiny bubbles, increasing the contact area between the clean air and the fermentation liquid, and improving the efficiency of oxygen dissolution.

[0027] like Figure 2 , Figure 3As shown, a vent valve 9 is fixedly connected to the upper side of the top cover 2. During the fermentation of the enzyme liquid, carbon dioxide will be released in the container, and the pressure will increase. It is necessary to release the gas through the vent valve 9 several times a day to avoid the pressure in the fermentation tank 1 being too high. A drain pipe 10 is fixedly connected to the lower side of the fermentation tank 1. A switch valve 11 is fixedly installed in the middle of the vent valve 9. When discharging, the fermented enzyme liquid is discharged through the drain pipe 10 by controlling the switch valve 11 to open and close.

[0028] It should be noted that this fruit enzyme fermentation equipment requires sterilization before use. After sterilization, remove the bolts securing the fermentation tank 1 and top cover 2. Hold handle 4 and remove the top cover 2 from the fermentation tank 1. Place the fruit, yeast, lactic acid bacteria, and other fermentation materials into the fermentation tank 1 in the correct proportions. Initially, the materials are placed on top of the first filter screen 7. After adding an appropriate amount of material, place the top cover 2 back onto the fermentation tank 1 and secure them with bolts. During fermentation, clean air needs to be supplied to the fermentation tank 1 in a measured quantity. Air pump 801 supplies external air to the air inlet pipe 803. Gas flow meter 802 monitors the air flow to prevent excessive or insufficient air intake. The air entering the air inlet pipe 803 first passes through the inlet... The air is sterilized by irradiation through the trachea 803, and then filtered by the ultraviolet germicidal lamp 804. The clean air is then dispersed into bubbles through the microporous aeration disc 806 and mixed with the fermentation liquid. During the mixing process, the servo motor 601 is started to drive the stirring blade 603 to rotate, mixing and stirring the materials in the fermentation tank 1, so that the materials are fully and evenly integrated, improving the fermentation efficiency. The carbon dioxide produced during fermentation is discharged through the vent valve 9. It needs to be discharged regularly to avoid increasing the pressure inside the fermentation tank 1. After fermentation is completed, the switch valve 11 is opened to discharge the fermentation liquid from the drain pipe 10. When discharging the fermentation liquid, the servo motor 601 can be turned on to rotate the scraper 604, pushing the material on the first filter screen 7 to prevent the first filter screen 7 from being blocked, which would affect the efficiency of the fermentation liquid discharge. After the fermentation liquid is discharged, the top cover 2 is removed to dispose of solid waste such as fruit residue.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
