In existing chicken feet fermentation devices, the added gas is prone to uneven dispersion inside the tank, affecting the stability of the fermentation chemical reaction and the taste of the processed chicken feet.
Connecting pipes and return pipes are installed on the side wall of the tank. The gas is extracted, mixed, heated and then returned to the tank by the control of a solenoid valve. Combined with the circulation of the exhaust pump, the gas is ensured to be evenly dispersed in the tank. At the same time, activated carbon blocks are used to absorb odors and remove odors from the gas.
This achieves uniform gas dispersion within the tank, improving the stability of the fermentation process and the texture of the chicken feet, while simplifying the cleaning process.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of chicken feet processing technology, specifically a high-efficiency fermentation device for chicken feet. Background Technology
[0002] Chicken feet, also known as phoenix feet, are a popular delicacy in China and other East Asian countries. They are typically stewed, fried, or marinated with various seasonings and sauces, resulting in a tender texture and unique flavor. A chicken feet fermentation device is a specialized apparatus for fermenting chicken feet. By controlling temperature, humidity, and time, it promotes the natural fermentation of the chicken feet in seasonings, producing a unique flavor. This device usually includes a temperature control system, humidity regulator, and ventilation system to ensure stable environmental conditions throughout the fermentation process. Fermented chicken feet not only have a richer flavor but also enhanced nutritional value, making them a favorite among many diners.
[0003] Existing chicken feet fermentation devices typically consist of a tank with electric heating wires installed on the inner wall to heat the chicken feet material, ensuring a suitable temperature for fermentation. During fermentation, nitrogen or other gases are usually added to stabilize the chemical reaction. However, these gases are often added all at once through pipes, leading to uneven dispersion within the tank and affecting the stability of the fermentation process, ultimately impacting the flavor of the processed chicken feet. Therefore, we propose a high-efficiency chicken feet fermentation device. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency fermentation device for chicken feet, so as to solve the problem mentioned in the background art that the added gas is easily unevenly dispersed inside the tank.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency fermentation device for chicken feet, comprising a tank body, a fixed seat embedded in the side wall of the tank body, a connecting pipe provided on the side wall of the fixed seat, an air pump provided at the top of the connecting pipe, an air inlet box provided at the top of the air pump, an adjusting component slidably fitted inside the air inlet box, a fixing ring fixedly connected to the top of the adjusting component, a rotating screw cooperating with the air inlet box passing through the top of the fixing ring, a three-way pipe provided at the output end of the connecting pipe, a solenoid valve one and a solenoid valve two provided at the output end of the three-way pipe, a return pipe provided at the output end of the solenoid valve two, and a heating cylinder sleeved outside the return pipe.
[0006] Preferably, an adsorption box is provided at one output end of the solenoid valve, and an activated carbon block is provided inside the adsorption box.
[0007] Preferably, the adsorption box has an exhaust port at its output end and a support at its bottom.
[0008] Preferably, the tank body is provided with a discharge gate on the side wall and a placement seat at the bottom of the tank body.
[0009] Preferably, the solenoid valve has support pillars fixed to its two side walls, and the support pillars are fixed to the side walls of the tank.
[0010] Preferably, the output end of the reflux pipe is connected to the tank body, and the top of the tank body is provided with a feeding port.
[0011] Preferably, the bottom of the air inlet box is provided with an air hole, and the top of the air hole is provided with a connecting piece that cooperates with the rotating screw.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, by setting a connecting pipe and a return pipe on the side wall of the tank and opening solenoid valve two and closing solenoid valve one, allows the gas inside the tank to be drawn out to the connecting pipe by the exhaust pump inside the tank. After the rotating screw is rotated, the adjusting part is moved upward, which causes the gas pump to run, and then the gas to be added is drawn into the connecting pipe through the air inlet box to mix with the gas in the tank. Then the gas passes through the three-way pipe and the heating cylinder is energized, so that the mixed gas flow is heated and flows back into the tank. This allows for convenient gas addition to the tank, so that the added gas can mix with the original gas in the tank inside the connecting pipe. With the circulation of the exhaust pump, the added gas can be more evenly dispersed inside the tank, which is convenient for fermenting chicken feet.
[0014] 2. After the tank is used, the second solenoid valve is closed and the first solenoid valve is opened. At this time, the gas inside the tank can enter the adsorption box through the three-way pipe. Then, the activated carbon block inside the adsorption box can adsorb the odor in the gas. Finally, the gas can be discharged from the exhaust port, thus realizing the simultaneous discharge and treatment of odor in the gas inside the tank, which is convenient for cleaning and exhausting the inside of the tank.

[0024] In some embodiments, a common slow-speed motor is provided on the rear side of the tank 100, and a stirring rod connected to the power output end of the slow-speed motor is provided inside the tank 100, so that the slow-speed motor can drive the stirring rod to stir the material inside the tank 100 when it runs.
[0025] Specifically, the output end of the solenoid valve 141 is provided with an adsorption box 142, and an activated carbon block 143 is provided inside the adsorption box 142.
[0026] Furthermore, the adsorption box 142 is provided with an exhaust port 144 at the output end, and a support is provided at the bottom of the adsorption box 142.
[0027] Furthermore, a discharge gate 170 is provided on the side wall of the tank body 100. A rubber ring that fits into the tank body 100 is provided on the side wall of the discharge gate 170.

[0029] It is worth noting that the output end of the reflux pipe 160 is connected to the tank body 100, and the top of the tank body 100 is provided with a feeding port 110.
[0030] It is worth noting that an air vent is provided at the bottom of the air intake box 122, and a connecting piece is provided at the top of the air vent to cooperate with the rotating screw 125.

Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.
[0032] Working principle: By installing a connecting pipe 130 and a return pipe 160 on the side wall of the tank 100, and opening solenoid valve 2 151 and closing solenoid valve 1 141, the exhaust pump built into the tank 100 operates to extract the gas inside the tank 100 into the connecting pipe 130. Then, rotating the screw 125 causes the adjusting component 123 to move upward, activating the gas pump 121. This allows the gas to be added to be drawn into the connecting pipe 130 through the air inlet box 122, mixing with the gas in the tank 100. The gas then passes through the three-way pipe 140, and the heating cylinder 161 is energized, heating the mixed gas flow back into the tank 100. This allows for convenient gas filling of the tank 100. The added gas can mix with the original gas in the tank 100 inside the connecting pipe 130. With the circulation of the exhaust pump, the added gas can be more evenly dispersed inside the tank 100, which is convenient for fermenting chicken feet. After the tank 100 is used, the solenoid valve 2 151 is closed and the solenoid valve 1 141 is opened. At this time, the gas inside the tank 100 can enter the adsorption box 142 through the three-way pipe 140. Then, the activated carbon block 143 inside the adsorption box 142 can adsorb the odor in the gas. Finally, the gas can be discharged from the exhaust port 144. This allows for the simultaneous discharge and treatment of odors in the gas inside the tank, which is convenient for cleaning and exhausting the inside of the tank 100.
