Description

Technical Field

[0001] This utility model relates to the field of almond oil processing technology, and in particular to an aerobic stirring device for almond oil fermentation. Background Technology

[0002] Almonds, also known as almond kernels or almond nut, are the dried fruit of plants in the genus *Amyda* of the Rosaceae family. They are a very important tree species used for dried fruit, oil, and medicinal purposes. The world's annual production is around 1.2 million tons, ranking first among the world's four major dried fruits. In the 1970s, when American almonds were exported to my country, they were mistakenly translated as "American almonds" and this misinterpretation became widespread. Almonds are rich in protein, vitamin E, and dietary fiber, and are usually processed into almond oil for widespread market distribution.

[0003] In the production and processing of almond oil, fermentation is usually carried out to improve the quality and taste of the oil, and a large fermentation tank is used to complete this process. For example, an aerobic fermentation and automatic stirring device (patent number: 202223421241.2) includes a mixing cylinder. A hollow shaft is rotatably installed at the center of the inner cavity of the mixing cylinder via a bearing. Several stirring tubes are connected to the bottom of the outer circumference of the hollow shaft. The top and bottom of the stirring tubes are connected to a through pipe. A drive component is installed at the top of the mixing cylinder, and the hollow shaft is connected to the drive component for transmission. An oxygen pump is fixedly installed at the top of the mixing cylinder. This invention uses an oxygen pump to inject oxygen into the hollow shaft through an air duct. The oxygen passes through the stirring tube and is discharged through the connecting pipe. This allows the peanut bran to be agitated by the stirring tube while the connecting pipe dynamically introduces oxygen into the peanut bran. Furthermore, during the later stage of static fermentation of the peanut bran, the oxygen pump injects oxygen into the hollow shaft through the air duct. The oxygen passes through the connecting pipe and enters the peanut bran, enabling aerobic fermentation of the peanut bran. This results in good fermentation effect, high efficiency, and little or no odor in the fermented peanut bran.

[0004] Existing aerobic fermentation stirred tanks can achieve dynamic oxygenation, but the location for adding oxygen is relatively limited, mostly using a bottom inlet pipe. This cannot guarantee the uniformity of oxygen addition into the fermentation tank. In addition, the stirring structure is mostly a simple shaft type with a small stirring area, which cannot guarantee the uniformity and sufficiency of stirring, making it difficult to achieve uniform oxygen diffusion. Furthermore, other gases are generated during fermentation, causing the gas pressure inside the fermentation tank to rise. If not discharged in time, this can cause certain compression damage to the tank. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing aerobic fermentation mixing tanks can achieve dynamic oxygenation, but the location for adding oxygen is limited, mostly using a bottom inlet pipe. This cannot guarantee the uniformity of oxygen addition into the fermentation tank. In addition, the mixing structure often uses a simple shaft type with a small mixing area, which cannot guarantee the uniformity and sufficiency of mixing, thus making it difficult to achieve uniform oxygen diffusion. Furthermore, other gases are generated during fermentation, causing the gas pressure inside the fermentation tank to rise. If these gases are not discharged in time, they will cause certain compression damage to the tank.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0007] An aerobic stirring device for almond oil fermentation includes a tank, which is cylindrical, with a liquid collection pipe at the bottom of the tank, an inlet and outlet pipe connected to the bottom of the liquid collection pipe, and a top cover at the top of the tank.

[0008] The top cover is threadedly connected to the tank body. A vertical stirring shaft is provided in the middle of the top cover. The stirring shaft is hollow and in the form of a tube. The bottom of the stirring shaft extends into the bottom of the tank body and the top extends out of the top cover. The part of the stirring shaft that extends into the tank body is provided with two pairs of stirring paddles arranged vertically.

[0009] Each pair of stirring paddles is in the shape of a flat cylinder. The stirring paddle is hollow inside. A connecting hole is opened on the stirring shaft body corresponding to the position of the stirring paddle. Several ventilation holes are opened on the end face of the stirring paddle. A waterproof and breathable membrane is provided on the inner wall of both end faces of the stirring paddle. A transmission gear is sleeved on the part of the stirring shaft that extends out of the top cover. A motor is provided on the top surface of the top cover.

[0010] The motor drives a rotating shaft, and a drive gear is connected to the top of the rotating shaft. The drive gear is connected to the transmission gear. A rotary joint is provided at the top of the stirring shaft, and a vent pipe is connected to the top of the rotary joint. The rotary joint is screwed to the stirring shaft and fixedly connected to the vent pipe.

[0011] Preferably, the liquid receiving pipe is funnel-shaped. The funnel-shaped liquid receiving pipe can empty the almond vegetable oil in the tank as much as possible during discharge.

[0012] Preferably, the bottom of the stirring shaft is close to the bottom of the liquid collection pipe. Extending the stirring shaft as far as possible throughout the tank expands the stirring range, resulting in more uniform oxygen diffusion and more thorough fermentation.

[0013] Preferably, a sealing gasket is provided at the screw connection between the tank body and the top cover. The sealing gasket can prevent almond oil leakage during the stirring and fermentation process.

[0014] Preferably, the top cover has two symmetrically arranged hanging ears on its side wall, with a through hole in the middle of each hanging ear. The hanging ears allow the top cover to be rotated easily using an external mechanism.

[0015] Preferably, the top cover is provided with a vertical exhaust pipe, the bottom of which extends into the tank body and the top of which extends out of the top cover.

[0016] Preferably, an electrically controlled valve is provided at the part of the exhaust pipe that extends out of the top cover.

[0017] Preferably, a pressure sensor is provided on the bottom surface of the top cover, and a controller is provided inside the top cover. The controller is connected to the pressure sensor and the electronically controlled valve. By setting up an exhaust pipe and a pressure sensor, when a large amount of gas is generated in the tank during fermentation, causing the pressure to increase, the pressure sensor senses this and sends a signal to the controller. The controller then controls the electronically controlled valve to open, allowing the gas in the tank to be discharged through the exhaust pipe.

[0018] Preferably, the area of ​​the waterproof and breathable membrane is the same as the area of ​​the inner wall of the end face of the agitator. This ensures that the waterproof and breathable membrane completely covers the inner wall of the end face of the agitator, thereby preventing the almond oil in the tank from leaking into the agitator and agitator shaft.

[0019] Preferably, a booster pump is installed at the vent pipe section, and the booster pump is located on the top surface of the top cover. The booster pump can pressurize the introduced oxygen to ensure the pressure of the introduced oxygen.

[0020] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0021] (1) By setting a flat cylindrical stirring paddle and opening several ventilation holes on the end face of the stirring paddle, not only can the path of oxygen diffusion be increased, but also the range of stirring contact can be increased, which is conducive to improving the uniformity of oxygen diffusion and the fullness of stirring fermentation.

[0022] (2) By setting up a waterproof and breathable membrane, the almond oil in the tank can be effectively prevented from leaking into the agitator and agitator shaft; by setting up a pressure sensor, controller, electric valve and exhaust pipe, the pressure in the tank can be monitored in real time and automatic exhaust and depressurization can be achieved.
