[0002] Ghee is a solid fat extracted from milk and is widely used in religious ceremonies, food processing, traditional medicine and other fields. Ghee is divided into religious ghee and edible ghee. Religious ghee is pure fat, while the main component of edible ghee is fat and contains a small amount of protein. In the process of making edible ghee, the fat in the milk needs to be extracted. Usually, the fat is separated and the solid fat is extracted by manual tumbling or mechanical stirring.

[0021] The present invention will be described in detail in conjunction with the drawings in the embodiments of the present invention.

[0022] A dairy fermentation device includes a fermentation tank 101. An extraction pipe 201 is fixedly connected to the upper end of the fermentation tank 101. A multi-purpose pipe 301 is connected to the extraction pipe 201 through a control mechanism. A partition 302 is fixedly connected to the middle of the multi-purpose pipe 301. A sliding rod 303 is slidably connected to the middle of the partition 302. A sliding plug 304 is fixedly connected to the sliding rod 303. Two pumping holes 305 are opened on the extraction pipe 201. Both of the two pumping holes 305 are located above the partition 302. The lower end of the sliding rod 303 is connected to a stirring mechanism.

[0023] The stirring mechanism includes a support plate 401. The support plate 401 is fixedly connected to the lower end of the sliding rod 303. The support plate 401 is located below the partition 302. A plurality of straight bars 402 are rotatably connected to the support plate 401. A plurality of spiked portions 404 are fixedly connected to each straight bar 402. A torsion spring is installed at the rotational connection of each straight bar 402 and the support plate 401.

[0024] Two flow guiding grooves 403 are opened on each straight bar 402.

[0025] The upper end of the sliding rod 303 is fixedly connected to a pull rod 306.

[0026] The control mechanism includes an electric push rod 501. The moving end of the electric push rod 501 is fixedly connected to a lifting plate 502. A driving motor 504 is fixedly connected to the lifting plate 502. Gears 503 are fixedly connected to both the output shaft of the driving motor 504 and the extraction pipe 201, and the two gears 503 are in meshing transmission.

[0027] An observation groove is formed in the extraction pipe 201, and a transparent glass is inlaid in the observation groove.

[0028] A scale mark 202 is arranged on the surface of the extraction pipe 201.

[0029] A pressure pump 103 is fixedly connected to the fermentation tank 101, and a feed pipe 104 is fixedly connected to the pressure pump 103.

[0030] A discharge pipe 103 and a plurality of legs 102 are installed at the bottom of the fermentation tank 101, and a valve is installed in the discharge pipe 103.

[0031] A process for processing dairy products using a dairy product fermentation device, the process comprising the following steps:

[0032] Step 1: First, the staff connects the feed pipe 104 on the pressure pump 103 to a container filled with whole milk.

[0033] Step 2: Use the pressure pump 103 to pump the whole milk into the fermentation tank 101, heat the milk inside through a heating device externally connected to the fermentation tank 101, and at the same time add lactic acid bacteria to the fermentation tank 101.

[0034] Step 3: The grease gradually solidifies and agglomerates and floats above the whey. A plurality of sliding rods 303 perform stirring treatment on the milk, and a plurality of spike parts 404 on the plurality of sliding rods 303 cut and break the solidified grease, so that the solidified grease becomes granular and floats on the surface of the whey.

[0035] Step 4: Continue to pour the milk. As the liquid level rises, the grease particles will also float upward and gradually concentrate at the center position of the fermentation tank and finally enter the extraction pipe 201.

[0036] Step 5: A negative pressure is generated in the cavity formed by the extraction pipe 201 and the partition 302, and the solidified grease particles in the extraction pipe 201 are sucked through the two pumping holes 305, so that the solidified grease particles enter the cavity formed by the extraction pipe 201 and the partition 302.

[0037] See Figures 4 - 8 ,

[0038] When using the fermentation device, first, the staff connects the feed pipe 104 on the pressure pump 103 to the container filled with whole milk, and then uses the pressure pump 103 to pump the whole milk into the fermentation tank 101. The milk inside is heated by the heating device externally connected to the fermentation tank 101. At the same time, lactic acid bacteria are added into the fermentation tank 101 to make the milk in the fermentation tank 101 ferment. During the fermentation process of the milk, by controlling the driving motor 504 to drive two meshing transmissions, the extraction pipe 201 can be driven to rotate. Since the extraction pipe 201 is limited and slides with the slide bar 303 through a rectangular convex rib, the extraction pipe 201 can drive the slide bar 303 to rotate while rotating. The slide bar 303 drives the supporting plate 401 at the lower end to rotate, and the supporting plate 401 drives a plurality of straight bars 402 to rotate. The plurality of straight bars 402 can automatically unfold under the action of the torsion spring, facilitating the subsequent stirring treatment of the milk.

[0039] Due to the slight fermentation of lactic acid bacteria in the milk, the solidified curd makes the milk fat globules aggregate and float upward, forming a surface cream, accelerating the floating of the oil in the milk. Under the continuous stirring action, the oil gradually solidifies and agglomerates, so that it can float above the whey. Under the rotating action of the plurality of slide bars 303, the plurality of slide bars 303 play a role in stirring the milk, making the lactic acid bacteria evenly dispersed in the milk and improving the fermentation effect. The plurality of spiked parts 404 on the plurality of slide bars 303 can cut and break the solidified oil, making the solidified oil become granular and float on the surface of the whey, thus facilitating the collection and treatment of the solidified oil.

[0040] See Figures 5 - 8 ,

[0041] After the oil particles float to the surface, the staff discharges the whey by opening the valve in the discharge pipe 103, and then uses the pressure pump 103 to continue adding milk to the fermentation tank 101. The above operations are repeated to ferment and degrease the milk. As the oil particles gradually increase, the staff continues to fill the milk. Since the fermentation tank 101 is conical, as the liquid level rises, the oil particles will also float upward and can gradually concentrate at the center of the fermentation tank, and finally enter the extraction pipe 201, achieving the effect of aggregating the oil particles. At this time, control the multi-purpose pipe 301 to stop rotating. The height of the oil particles is higher than the height of the two pumping holes 305. The staff manually pulls the pull rod 306 upward. The pull rod 306 drives the sliding rod 303 to move upward, and the sliding rod 303 drives the sliding plug 304 to slide upward, creating a negative pressure in the cavity formed by the extraction pipe 201 and the partition 302. Thus, the solidified oil particles in the extraction pipe 201 can be sucked through the two pumping holes 305, enabling the solidified oil particles to enter the cavity formed by the extraction pipe 201 and the partition 302, realizing the function of collecting the solidified oil particles. Since the diameter of the extraction pipe 201 is relatively narrow compared to the fermentation tank 101, the thickness of the solidified oil particles can be increased, further facilitating collection. The collected solidified oil particles are processed by extrusion molding to obtain the finished ghee.

[0042] Compared with the conventional method of making ghee, the advantage of this application is that it can use fermentation to accelerate the separation of oil, and the separated oil is in a solid state. Utilizing the floating property of the oil, it is convenient to centrally collect the solidified oil, speeding up the oil collection speed and facilitating subsequent direct extrusion molding to obtain ghee.

[0043] See Figures 5 - 8 ,

[0044] While sucking the solidified oil particles, the upward sliding of the sliding rod 303 can simultaneously drive the support plate 401 to move upward. After the multiple straight bars 402 come into contact with the lower end of the multi-purpose pipe 301, they automatically gather towards the middle until the multiple straight bars 402 are all in a vertical state. The space at the lower part of the multi-purpose pipe 301 is used to accommodate the multiple straight bars 402, facilitating the subsequent removal of the multi-purpose pipe 301 from the fermentation tank 101. The diversion grooves 403 on the straight bars 402 play a role in guiding the liquid. When the straight bars 402 are in a vertical state, it is convenient for the whey attached to the surface to flow downward.

[0045] When the multiple straight bars 402 need to be used again, control the sliding rod 303 to slide downward, so that the sliding plug 304 automatically resets. At the same time, the sliding rod 303 drives the multiple straight bars 402 to extend out of the lower end of the multi-purpose pipe 301. When the multiple straight bars 402 are fully extended, the multiple straight bars 402 can automatically unfold under the action of the torsion spring, facilitating the stirring of milk and the cutting of solidified oil.

[0046] SeeFigure 5 ,

[0047] Since the extraction tube 201 is provided with an observation groove in which a transparent glass is inlaid, when the solidified grease particles enter the extraction tube 201, the staff can control the amount of milk added according to the height of the solidified grease particles, thereby preventing the solidified grease particles from overflowing through the extraction tube 201.

[0048] The scale mark 202 is used to mark the approximate volume of the solidified grease particles corresponding to the height, so that it is convenient for the staff to understand the approximate volume of the solidified grease by comparing the height of the solidified grease particles with the data on the scale mark 202, which is convenient for recording data and subsequent processing.
