Description

Technical Field

[0001] This utility model relates to the field of butter production technology, and in particular to a device for producing unsalted butter. Background Technology

[0002] Butter is a solid fat processed from milk. It is a dairy product made from fresh or fermented cream or milk through churning. During the production of butter, churning and heating of milk are required to separate the milk fat from the milk emulsion. After churning, the milk emulsion will separate into two parts: solid butter particles and liquid buttermilk. After the milk is condensed, the butter particles need to be separated. The existing separation method is to pour the mixture into a container with a filter screen and use the filter screen to filter out the liquid buttermilk, leaving solid butter particles.

[0003] In the prior art, the condensing and filtering devices for butter are set up separately. The filtering after condensing requires separate operation, which is cumbersome and inefficient. In addition, the filter screen is fixed and the filtration method relies on the fluid dynamics, which results in low filtration efficiency. In view of the above, this application proposes an unsalted butter production device. Utility Model Content

[0029] Example 1

[0030] Reference Figure 1-4 An unsalted butter production device, comprising:

[0031] A milk mixing and condensing mechanism 1, with a base 4 underneath it;

[0032] The condensed milk mixing mechanism 1 includes a mixing tank 101. A feeding valve 107 is fixedly connected to the top left side of the mixing tank 101, allowing raw materials to be added into the mixing tank 101. The bottom inner wall of the mixing tank has a conical structure and is fixedly connected to a discharge solenoid valve 106. The discharge solenoid valve 106 has a built-in wireless remote control module, which is matched with an external remote control. The external remote control can control the opening and closing of the discharge solenoid valve 106. A rotating rod 102 is rotatably mounted on the top inner wall of the mixing tank 101. A first circular hole is formed on the top inner wall of the mixing tank 101, and a first sealed bearing is fixedly fitted inside the first circular hole. The inner side of the inner ring of the first sealed bearing is fixedly connected to the outer side of the rotating rod 102. The first sealed bearing serves to supply rotation... The effect of rotating rod 102 is that the top of the mixing tank 101 is fixedly connected to the first drive motor 103, which is fixedly connected to the top of the rotating rod 102. Multiple stirring blades are fixedly connected to both sides of the rotating rod 102. A U-shaped scraper 104 is fixedly connected to the right side of the rotating rod 102. An electric heating sleeve 105 is fixedly fitted inside the mixing tank 101. The electric heating sleeve 105 is used to heat the condensed milk during the process. Its heating principle is existing technology and will not be described in detail here. The top and bottom of the U-shaped scraper 104 are in movable contact with the top inner wall and bottom inner wall of the mixing tank 101, respectively. The right side of the U-shaped scraper 104 is in movable contact with the inner wall of the electric heating sleeve 105. The U-shaped scraper 104 is used to scrape and clean the raw materials adhering to it during the stirring process.

[0033] In this implementation scheme: the raw materials are added into the mixing tank 101 through the feeding valve 107, and then the first drive motor 103 is started to drive the rotating rod 102 to rotate. The rotating rod 102 drives multiple stirring blades to rotate and stir the raw materials inside the mixing tank 101. The rotating rod 102 also drives the U-shaped scraper 104 to rotate and scrape off the adhering raw materials. At the same time, the electric heating jacket 105 is turned on to heat the raw materials inside the mixing tank 101. By combining stirring with heating, effective condensed milk operation can be achieved.

[0034] It should be noted that: the first drive motor 103 can preferably be a Siemens (SIEMENS) frequency converter motor, and the electric heating jacket 105 can preferably be a stainless steel flange type electric heating jacket, which uses resistance heating. The current passes through the heating wire (resistance wire) inside the heating jacket to generate heat. The heat is evenly conducted to the material in contact with it in the mixing tank 101 through the thermally conductive insulating material and the metal sheath, thereby achieving heating of the entire material.

[0035] It should also be noted that the mixing tank 101 consists of a first circular barrel with an opening at the top and a first cover. The first cover is fixed to the top of the first circular barrel by external bolts (not shown in the figure).

[0036] Furthermore:

[0037] A non-salt butter production device also includes a filter box 2, which is fixedly connected to the bottom of a mixing tank 101. The bottom of the filter box 2 is fixedly connected to the top of a base 4. Four support legs are fixedly connected between the top of the base 4 and the bottom of the filter box 2. The support legs achieve the fixed connection between the base 4 and the filter box 2. A discharge valve 201 is fixedly connected to the bottom left side of the filter box 2. The filtered liquid buttermilk can be discharged through the discharge valve 201. The bottom end of the discharge solenoid valve 106 extends into the filter box 2.

[0038] Centrifugal filtration mechanism 3 is installed on filter box 2;

[0039] The centrifugal filtration mechanism 3 includes a stainless steel filter cartridge 301 housed within a filter box 2. A cover 302 is fixedly connected to the top of the stainless steel filter cartridge 301. The cover 302 is rotatably and sealingly fitted onto a discharge solenoid valve 106. A second circular hole is provided at the top of the cover 302, and a second sealing bearing is fixedly fitted within this hole. The inner side of the inner ring of the second sealing bearing is fixedly connected to the outer side of the discharge solenoid valve 106. The second sealing bearing provides a sealed rotation between the cover 302 and the discharge solenoid valve 106. A rotating sleeve 303 is fixedly connected to the bottom of the stainless steel filter cartridge 301, extending to the bottom of the filter box 2. The filter box 2 is rotatably and sealingly fitted onto the rotating sleeve 303. A third circular hole is provided on the inner wall of the bottom of the stainless steel filter cartridge 2, and a third sealing bearing is fixedly fitted within this hole. The inner side of the inner ring of the bearing is fixedly connected to the outer side of the rotating sleeve 303. The third sealing bearing serves to provide a sealing and rotating installation for the rotating sleeve 303. An outer gear ring 306 located below the filter box 2 is fixedly sleeved on the rotating sleeve 303. A gear 307 meshes on the left side of the outer gear ring 306. A second drive motor 308 is fixedly installed at the bottom of the filter box 2. An L-shaped support is fixedly connected to the left side of the bottom of the filter box 2. The inner wall of the bottom of the L-shaped support is fixedly connected to the bottom of the second drive motor 308. The L-shaped support is used to support and fix the second drive motor 308. The top end of the output shaft of the second drive motor 308 is fixedly connected to the bottom of the gear 307. The second drive motor 308, the gear 307 and the outer gear ring 306 cooperate to drive the rotating sleeve 303 to rotate. A sealing and discharging assembly is installed on the rotating sleeve 303.

[0040] The sealing and discharging assembly includes a sealing plate 304 that is movably fitted inside a rotating sleeve 303. The top of the sealing plate 304 is inclined, and a sealing sleeve is adhesively bonded to the outer side of the sealing plate 304. The outer side of the sealing sleeve is in close contact with the inner wall of the rotating sleeve 303. The sealing sleeve achieves a seal between the sealing plate 304 and the rotating sleeve 303. The inclined surface of the sealing plate 304 is angled downwards to the right, facilitating rapid material feeding. The sealing plate 304 is used for... The interior of the rotating sleeve 303 is sealed. The bottom of the sealing plate 304 is fixedly connected to a T-shaped rod 305 that is in movable contact with the bottom of the rotating sleeve 303. Threaded grooves are opened on both sides of the bottom of the rotating sleeve 303. T-shaped fixing bolts are threaded in the threaded grooves. The T-shaped rod 305 is threaded on the two T-shaped fixing bolts. Bolt holes are opened on both sides of the bottom of the T-shaped rod 305. The bolt holes are threadedly connected to the corresponding T-shaped fixing bolts. The T-shaped fixing bolts are used to fix the T-shaped rod 305.

[0041] Collection box 5, with an opening at the top, is placed on top of base 4 and below filter box 2. Collection box 5 is used to collect the filtered solid butter particles.

[0042] In this implementation scheme: after the condensed milk is completed, the discharge solenoid valve 106 is opened by an external remote control, so that the condensed milk material inside the mixing tank 101 enters the stainless steel filter cartridge 301. Then, the second drive motor 308 is turned on to drive the gear 307 to rotate. The gear 307 drives the rotating sleeve 303 to rotate through the meshing external gear ring 306. The rotating sleeve 303 drives the stainless steel filter cartridge 301 to rotate centrifugally. While the stainless steel filter cartridge 301 rotates centrifugally, it shakes and filters the material inside, so that the liquid buttermilk is discharged into the filter box 2 through the stainless steel filter cartridge 301, and the solid butter particles are blocked inside the stainless steel filter cartridge 301.

[0043] After filtration, when removing the solid grease particles, rotate the two T-shaped fixing bolts in the opposite direction to move them out of their corresponding threaded grooves, releasing the T-shaped rod 305 from its fixation. At this point, the T-shaped rod 305 can be moved downwards to move the sealing plate 304 out of the rotating sleeve 303, releasing the obstruction of the stainless steel filter cartridge 303 and the rotating sleeve 303, allowing the solid grease particles inside the stainless steel filter cartridge 303 to be discharged into the collection box 5 along the inclined surface of the sealing plate 304.

[0044] It should be noted that: the second drive motor 308 can preferably be a Siemens (SIEMENS) frequency converter motor, and the discharge solenoid valve 106 can preferably be model YWL-01DIN, which has a built-in wireless receiver module controller to receive remote commands and control the circuit to drive the discharge valve to operate.

[0045] In terms of power supply, all electrical components of this device are connected to the local mains power. The mains power is connected to the power input interface of each device through conventional power distribution devices such as circuit breakers, contactors, and power modules (not marked in the figure) and flexible wires to form a complete power supply circuit. This power supply scheme is a conventional power distribution method for industrial equipment and is a mature and well-known technical means, so it will not be described in detail here.

[0046] Additionally, it should be noted that the filter box 2 consists of a second circular barrel with an open top and a second cover. The second cover is fixed to the top of the second circular barrel by external bolts (not shown in the figure), and the second cover is fixedly sleeved on the discharge solenoid valve 106.

[0047] Working principle: During use, the raw materials are added into the mixing tank 101 through the feeding valve 107. Then, the first drive motor 103 is started. The output shaft of the first drive motor 103 drives the rotating rod 102 to rotate. The rotating rod 102 drives multiple stirring blades to rotate and stir the raw materials inside the mixing tank 101. The rotating rod 102 also drives the U-shaped scraper 104 to rotate and scrape off the adhering raw materials. At the same time, the electric heating jacket 105 is turned on to heat the raw materials inside the mixing tank 101. By combining stirring with heating, effective condensed milk operation can be achieved.

[0048] After the condensed milk is completed, the discharge solenoid valve 106 is opened by an external remote control, allowing the condensed milk material inside the mixing tank 101 to enter the stainless steel filter cartridge 301. Then, the second drive motor 308 is turned on. The output shaft of the second drive motor 308 drives the gear 307 to rotate. The gear 307 drives the outer gear ring 306 that meshes with it to rotate. The outer gear ring 306 drives the rotating sleeve 303 to rotate. The rotating sleeve 303 drives the stainless steel filter cartridge 301 to rotate centrifugally. While the stainless steel filter cartridge 301 is rotating centrifugally, it is spun and filtered. Under the spun force, the liquid buttermilk is discharged into the filter box 2 through the stainless steel filter cartridge 301, and the solid butter particles are blocked inside the stainless steel filter cartridge 301. The condensed milk is directly discharged through centrifugal filtration, which eliminates the need for separate filtration by personnel and effectively improves the filtration efficiency, thereby improving work efficiency.

[0049] After filtration, when removing the solid grease particles, rotate the two T-shaped fixing bolts in the opposite direction to move them out of their corresponding threaded grooves, releasing the T-shaped rod 305 from its fixation. At this point, the T-shaped rod 305 can be moved downwards to move the sealing plate 304 out of the rotating sleeve 303, releasing the obstruction to the stainless steel filter cartridge 303 and the rotating sleeve 303. This allows the inclined surface of the sealing plate 304 to be tilted to the lower right, so that the solid grease particles inside the stainless steel filter cartridge 303 can be discharged into the collection box 5 along the inclined surface of the sealing plate 304, thereby achieving the purpose of discharging the filtered material.

[0050] Example 2

[0051] Reference Figure 5 This embodiment differs from Embodiment 1 in that: the bottom of the sealing plate 304 can also be rotatably mounted with the output shaft of the electric telescopic rod 6, wherein a first bearing is fixedly connected to the center of the bottom of the sealing plate 304, and the inner side of the inner ring of the first bearing is fixedly connected to the outer side of the output shaft of the electric telescopic rod 6. The first bearing can drive the sealing plate 304 to rotate while the stainless steel filter cartridge 303 rotates, providing rotational action for the sealing plate 304. The bottom of the electric telescopic rod 6 is fixedly connected to the top of the base 4, and the electric telescopic rod 6 is used to drive the sealing plate 304 to move vertically.

[0052] It should be noted that the electric telescopic pole 6 has a built-in wireless remote control module, which can be used to remotely control the opening and closing of the electric telescopic pole 6 via an external remote control. The preferred model of the electric telescopic pole 6 is IA12-100-10-50-IP54. The wireless remote control module receives wireless signals from the remote control, decodes them, and controls the polarity of the output power through the internal H-bridge circuit or relay, thereby precisely controlling the forward, reverse, and stop of the push rod motor.

[0053] The usage method of this embodiment is as follows: The difference from Embodiment 1 is that it also has the following functions: After filtration is completed, when the solid butter particles are removed, the electric telescopic rod 6 is activated in reverse. The output shaft of the electric telescopic rod 6 drives the sealing plate 304 to move out of the rotating sleeve 303, releasing the obstruction of the stainless steel filter cylinder 303 and the rotating sleeve 303, and making the inclined surface of the sealing plate 304 tilt to the lower right, so that the solid butter particles inside the stainless steel filter cylinder 303 are discharged into the collection box 5 along the inclined surface of the sealing plate 304, thereby achieving the purpose of discharging after filtration. Moreover, the electric drive discharge method is convenient for personnel operation and can be effectively applied to the production line.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
