Description

Technical Field

[0001] The utility model relates to the technical field of storage equipment, in particular to a raw material temporary storage tank. Background Technique

[0002] Buffalo is a kind of livestock that adapts to the tropical and subtropical climate environment and has many precious biological characteristics. It is considered by the Food and Agriculture Organization of the United Nations as one of the livestock with the greatest development potential and value. The quality of buffalo milk is very excellent and can be regarded as the best in milk, and its value is equivalent to 2 times that of the milk of Holstein cows. The International Buffalo Federation determined the development trend of buffalo in the new century as "mainly for milk use and supplemented by meat and draft" at the 6th World Buffalo Congress, and clarified that the buffalo milk industry will become a new industry. The relatively high whey protein in buffalo milk increases its nutritional value. At the same time, the non-protein nitrogen content is relatively low, and it has a low sodium and chlorine content, a high calcium content and contains oligosaccharides, which has an immunomodulatory effect. According to FAO statistics, in 2005, the inventory of buffalo in China was 22.7452 million heads, ranking third in the world; the output of buffalo milk was 126 million tons. The buffalo milk industry in China started relatively late. However, due to the unique potential and resources for developing the buffalo milk industry in China, coupled with the continuous in-depth scientific research, as well as the boost of international development projects, the guidance of national industrial policies and the promotion of market factors, the buffalo milk industry will surely have a broad development prospect.

[0003] Buffalo milk has a high milk fat content and large fat globules. Therefore, during the processing and storage process, unstable phenomena such as fat floating and the formation of a fat ring at the top are likely to occur. Especially for buffalo milk after high-temperature sterilization, fat floating is more serious. In the prior art, due to the serious fat floating of buffalo milk after high-temperature sterilization, the pasteurization method is mostly used to disinfect and sterilize buffalo milk. However, most of the existing temporary storage tanks for buffalo milk use ordinary dairy product storage tanks for temporary storage, that is, directly pour buffalo milk into a closed tank for storage. Such storage tanks cannot well solve the problems of fat floating and the formation of a fat ring at the top of buffalo milk, seriously affecting the quality of buffalo milk. In addition, in the prior art, the pasteurization method is also mostly used to sterilize buffalo milk in some large dairy product processing plants. However, the equipment used in the processing plants is large in volume, high in cost, and has great limitations, and such equipment is not suitable for some individual farmers, while the existing small equipment cannot complete the pasteurization process. Content of the Utility Model

[0004] Therefore, to address the above deficiencies, the present utility model provides a raw material temporary storage tank, including a storage tank. The storage tank includes a tank body, which from the outside to the inside sequentially includes a heat insulation layer, a first heat conduction layer, and a second heat conduction layer. A first interlayer is formed between the heat insulation layer and the first heat conduction layer, and a cooling coil is provided in this first interlayer. A heating device is provided at the bottom of the first heat conduction layer. A second interlayer is formed between the first heat conduction layer and the second heat conduction layer, and the second interlayer can accommodate a heat exchange liquid. A first liquid inlet and a second liquid inlet are provided at the upper part of the second interlayer, and a liquid outlet is provided at the lower part;

[0005] A tank cover is sealed on the top of the tank body, and a temperature sensor is further provided inside the tank body;

[0006] The temporary storage tank further includes a controller for controlling the output power of the heating device and the output temperature of the cooling coil.

[0007] The present utility model uses the pasteurization method to disinfect and sterilize buffalo milk. Heat is generated by the heating device to heat the first heat exchange liquid, and then the heat exchange liquid exchanges heat with the milk to heat it to a preset temperature, thereby realizing the disinfection treatment of buffalo milk. During refrigeration, the first heat exchange liquid is discharged from the liquid outlet, and the second heat exchange liquid cooled to the preset temperature is injected into the second interlayer through the second liquid inlet. The cooling coil exchanges cold energy with the second heat exchange liquid, and then the second heat exchange liquid transfers cold energy to the buffalo milk, thereby performing all-round refrigeration on the buffalo milk. During this process, the temperature is monitored by the temperature sensor, and the controller strictly controls the output power of the heating device and the output temperature of the cooling coil according to the temperature, effectively solving problems such as easy fat floating and formation of a fat ring at the top during the processing and storage of buffalo milk, being able to relatively well preserve the nutritional components in buffalo milk, with a simple operation process. Using the above method, compared with directly heating or cooling the buffalo milk by the heating device or the cooling coil, this method is easier to control the temperature. At the same time, after heating or cooling is completed, even if the heating device or the cooling coil stops working, it can keep the buffalo milk warm for a certain period of time.

[0008] Further, the storage tank includes:

[0009] A first power device, which is fixedly installed on the tank cover;

[0010] A rotating shaft, which is connected to the first power device and is driven by the first power device to rotate along its own circumference. The entire rotating shaft is placed inside the tank body, and a stirrer is fixed on the rotating shaft.

[0011] By driving the stirrer to stir the buffalo milk through the first power device, precipitation of macromolecular substances in the buffalo milk can be avoided, thereby maintaining the uniformity of the buffalo milk. At the same time, under the agitation of the stirrer, the heat transfer of the buffalo milk can be made more uniform.

[0012] Further, the inside of the rotating shaft is hollow;

[0013] The storage tank further includes a liquid inlet pipe, which is wrapped inside the rotating shaft. An outlet liquid channel is formed between the liquid inlet pipe and the rotating shaft. An outlet liquid hole communicating with the outlet liquid channel is provided at the end of the liquid inlet pipe;

[0014] The end of the rotating shaft away from the outlet liquid hole is connected to a return liquid pipe through a first rotary joint, and the end of the liquid inlet pipe away from the outlet liquid hole is connected to a connecting pipe through a second rotary joint.

[0015] A second heat exchange liquid is input into the liquid inlet pipe through the connecting pipe. The second heat exchange liquid flows into the outlet liquid channel through the outlet liquid hole. The cold quantity of the second heat exchange liquid passes through the rotating shaft and exchanges with the buffalo milk. Combined with the cold quantity exchange of the second heat exchange liquid in the second interlayer, the buffalo milk can be quickly cooled.

[0016] Further, the temporary storage tank further includes a first lifting assembly, and the tank cover is driven to slide vertically through the first lifting assembly.

[0017] Further, the first lifting assembly includes

[0018] A mounting part, on which the whole tank body is fixed;

[0019] A second power device;

[0020] A movable part, on which the tank cover is fixedly installed, and the movable part can slide vertically under the drive of the second power device.

[0021] Further, a lead screw is provided on the movable part;

[0022] A threaded ring is provided on the mounting part, and the threaded ring is in threaded cooperation with the lead screw. The threaded ring rotates along its circumferential direction under the drive of the second power device.

[0023] By driving the tank cover to slide vertically through the first lifting assembly, the tank cover can be lifted according to the actual working requirements, so as to facilitate the cleaning or maintenance of the inside of the tank body.

[0024] Further, the temporary storage tank further includes a second lifting assembly, and the whole storage tank is driven to slide vertically through the second lifting assembly.

[0025] Further, the second lifting assembly includes a third power device, and the first lifting assembly is driven to slide vertically through the third power device.

[0026] Further, the second lifting assembly further includes a sprocket transmission mechanism, and the end of the chain of the sprocket transmission mechanism is connected to the mounting part.

[0027] The storage tank is lifted by the second lifting component, and can be lifted to a preset height according to actual processing requirements, so as to facilitate the pipeline connection between the temporary storage tank and other equipment.

[0028] The utility model has the following advantages:

[0029] The utility model uses the pasteurization method to disinfect and sterilize buffalo milk. Heat is generated by the heating device to heat the first heat exchange liquid, and then the heat exchange liquid exchanges heat with the milk to heat it to a preset temperature, so as to realize the disinfection treatment of buffalo milk. When refrigerating, the first heat exchange liquid is discharged from the liquid outlet, and the second heat exchange liquid cooled to the preset temperature is injected into the second interlayer through the second liquid inlet. The cooling coil exchanges heat with the second heat exchange liquid, and then the second heat exchange liquid transfers cold to the buffalo milk, so as to cool the buffalo milk in all directions. During this process, the temperature is monitored by the temperature sensor, and the controller strictly controls the output power of the heating device and the output temperature of the cooling coil according to the temperature, effectively solving the problems such as fat floating and fat ring formation at the top that are prone to occur during the processing and storage of buffalo milk, and being able to preserve the nutritional components in the buffalo milk relatively intact. The operation process is simple. By using the above method, compared with directly heating or cooling the buffalo milk by the heating device or the cooling coil, this method is easier to control the temperature. At the same time, after heating or cooling is completed, even if the heating device or the cooling coil stops working, the buffalo milk can be kept warm for a certain period of time.

[0049] As described in the background art, existing temporary storage tanks for buffalo milk mostly use ordinary dairy product storage tanks for temporary storage, that is, directly pouring buffalo milk into a closed tank for storage. However, such storage tanks cannot well solve problems such as the floating of fat in buffalo milk and the formation of a fat ring at the top, seriously affecting the quality of buffalo milk. In addition, in the prior art, for some large dairy product processing plants, pasteurization is also mostly used to sterilize buffalo milk. However, the equipment used by the processing plants is large in volume, high in cost, and has great limitations, and such equipment is not suitable for some individual farmers, while existing small equipment cannot complete the pasteurization process.

[0050] Embodiment 1:

[0051] Therefore, in order to solve the above technical problems of the prior art, the present embodiment provides a raw material temporary storage tank herein, as Figure 1 shown. The raw material temporary storage tank includes a storage tank 100. The storage tank 100 includes a tank body 110, as Figure 2 shown. The tank body 110 sequentially includes a heat insulation layer 111, a first heat conduction layer 114, and a second heat conduction layer 116 from the outside to the inside. A first sandwich layer 113 is formed between the heat insulation layer 111 and the first heat conduction layer. A cooling coil 112 is provided in the first sandwich layer 113. A heating device 190 is provided at the bottom of the first heat conduction layer. A second sandwich layer 115 is formed between the first heat conduction layer and the second heat conduction layer. The second sandwich layer 115 can accommodate a heat exchange liquid. A first liquid inlet 117 and a second liquid inlet 119 are provided at the upper part of the second sandwich layer 115, and a liquid outlet 118 is provided at the lower part.

[0052] A tank cover 120 is sealed at the top of the tank body, and a temperature sensor is further provided inside the tank body 110.

[0053] The temporary storage tank further includes a controller for controlling the output power of the heating device and the output temperature of the cooling coil.

[0054] In this embodiment, the above-mentioned first liquid inlet is connected to the first heat exchange liquid source, and the second liquid inlet is connected to the second heat exchange liquid source. The above-mentioned first heat exchange liquid and second heat exchange liquid can be water.

[0055] In this embodiment, the above-mentioned cooling coil is connected to an external micro-cooling device, and the heat exchange medium can be cooled to a preset temperature by this micro-cooling device and then transported to the cooling coil.

[0056] In this embodiment, the pasteurization method is used to disinfect and sterilize the buffalo milk. During sterilization, first, the first heat exchange liquid is injected into the second interlayer through the first liquid inlet, and heat is generated by the heating device to heat the first heat exchange liquid. Then, the heat exchange liquid exchanges heat with the milk and heats it to the preset temperature, thereby realizing the pasteurization treatment of the buffalo milk. After the heating device works for a preset time, it stops working. Since the first heat exchange liquid still stores some heat itself, it will continue to exchange heat with the buffalo milk, so that the buffalo milk is maintained within the preset temperature range for a certain period of time. When the heat preservation reaches the preset time, since there is still a certain amount of heat inside the first heat exchange liquid, if the micro-cooling device is directly started to make the cooling coil perform the cooling work, the cooling rate is relatively slow. Therefore, when cooling the buffalo milk, the first heat exchange liquid needs to be discharged from the liquid outlet, and the second heat exchange liquid is injected into the second interlayer through the second liquid inlet. The cooling coil exchanges cold with the second heat exchange liquid, and then the second heat exchange liquid transfers cold to the buffalo milk, thereby performing all-round refrigeration on the buffalo milk. During this process, the temperature is monitored by a temperature sensor, and the controller strictly controls the output power of the heating device and the output temperature of the cooling coil according to the temperature, effectively solving problems such as fat floating and the formation of a fat ring at the top that are prone to occur during the processing and storage of buffalo milk, and being able to relatively well preserve the nutritional components in the buffalo milk. The operation process is simple. By adopting the above method, compared with directly heating or cooling the buffalo milk by the heating device or the cooling coil, this method is easier to control the temperature. At the same time, after heating or cooling is completed, even if the heating device or the cooling coil stops working, the buffalo milk can be kept warm for a certain period of time. In addition, indirectly heating or cooling the buffalo milk through the heat exchange liquid can avoid the milk from sticking to the bottom due to the excessive heat generated by the heating device, or the milk from solidifying due to the excessive cold generated by the cooling coil.

[0057] In this embodiment, as Figure 2 shown, the above-mentioned storage tank 100 may further include:

[0058] A first power device 130, which is fixedly installed on the tank cover 120;

[0059] The rotating shaft 140 is connected to the first power device. The first power device 130 drives the rotating shaft to rotate along its circumferential direction. The whole rotating shaft is placed inside the tank body 110, and a stirrer is fixed on the rotating shaft.

[0060] The first power device 130 drives the stirrer to stir the buffalo milk, which can prevent the precipitation of macromolecular substances in the buffalo milk, thus maintaining the uniformity of the buffalo milk. At the same time, under the agitation of the stirrer, the heat transfer of the buffalo milk can be made more uniform.

[0061] The above-mentioned first power device includes but is not limited to a servo motor, a stepper motor, a rotary cylinder or other devices that can drive the rotating shaft to rotate.

[0062] Embodiment 2:

[0063] Since it is necessary to quickly cool the buffalo milk after heating and keeping warm for a preset time to better preserve the nutrients in the buffalo milk, but in Embodiment 1, the cooling is carried out by the outer cooling coil and the second heat exchange liquid transferring cold quantity from outside to inside, and the cooling speed is slow.

[0064] Therefore, in order to improve the cooling speed, this embodiment makes improvements on the basis of Embodiment 1, as Figure 3 shown, different from Embodiment 1, the inside of the rotating shaft 140 in this embodiment is hollow;

[0065] The storage tank further includes a liquid inlet pipe 142, which is wrapped inside the above-mentioned rotating shaft 140. An outlet channel 143 is formed between the liquid inlet pipe 142 and the rotating shaft. An outlet hole 144 communicating with the outlet channel 143 is provided at the end of the liquid inlet pipe 142;

[0066] The end of the rotating shaft far from the outlet hole is connected to the return pipe 150 through a first rotary joint. The end of the liquid inlet pipe far from the outlet hole is connected to the connecting pipe 180 through a second rotary joint 160.

[0067] In this embodiment, through the above-mentioned first rotary joint and second rotary joint, the relative rotation of the liquid inlet pipe and the connecting pipe and the relative rotation of the rotating shaft and the return pipe 142 can be realized. At the same time, the connecting head of the liquid inlet pipe passing through the return pipe keeps relative rotation with the connecting head, so as to ensure the rotation of the rotating shaft while not affecting the circulation of the heat exchange liquid.

[0068] In this embodiment, the above-mentioned connecting pipe can be connected to the second interlayer through a pump; the return pipe is connected to the second interlayer.

[0069] As Figure 4As shown, in this embodiment, the second heat exchange liquid is input into the liquid inlet pipe through the connecting pipe 180. The second heat exchange liquid flows into the liquid outlet channel 143 through the liquid outlet holes 144. The cold quantity of the second heat exchange liquid is exchanged with the buffalo milk through the rotating shaft. Combined with the cold quantity exchange of the second heat exchange liquid in the second interlayer, the buffalo milk can be quickly cooled.

[0070] The second heat exchange liquid in the liquid outlet pipe can flow back to the second interlayer through the return pipe, thus realizing the circulating flow of the second heat exchange liquid.

[0071] Embodiment 3:

[0072] To facilitate the lifting of the tank cover, this embodiment proposes an optimization based on the above embodiment. For example, Figure 5 As shown, the temporary storage tank in this embodiment may further include a first lifting assembly 200, which drives the tank cover to slide vertically through the first lifting assembly 200.

[0075] a second power device 220;

[0076] a movable part 230, on which the tank cover is fixedly installed, and the movable part can slide vertically under the drive of the second power device 220.

[0078] Such as Figure 7 shown, a lead screw 240 is provided on the movable part;

[0079] a threaded ring is provided on the mounting part, and the threaded ring is in threaded cooperation with the lead screw. The threaded ring rotates along its own circumference under the drive of the second power device.

[0080] In this embodiment, the second power device drives the lead screw to rotate. Since the threaded ring is in threaded cooperation with the lead screw, the rotating lead screw will drive the mounting part fixed to the threaded ring to move linearly, thereby realizing the lifting of the tank cover.

[0081] Driving the tank cover to slide vertically through the first lifting assembly, the tank cover can be lifted according to the actual working requirements, so as to facilitate the cleaning or maintenance of the inside of the tank body.

[0082] In this embodiment, the connection between the movable part and the installation part can be through the guide rod 250 or a slider-guide connection.

[0083] Embodiment 4:

[0084] To adjust the height of the temporary storage tank according to actual installation requirements, this embodiment makes improvements on the basis of Embodiment 3. As Figure 8 shown, the temporary storage tank in this embodiment may further include a second lifting assembly 300, and the entire storage tank 100 is driven to slide vertically by this second lifting assembly.

[0085] As Figure 8 shown, the second lifting assembly includes a third power device 310, and the first lifting assembly is driven to slide vertically by this third power device.

[0086] The second lifting assembly further includes a sprocket transmission mechanism 330, and the end of the chain of the sprocket transmission mechanism 330 is connected to the installation part 210.

[0087] By driving the storage tank to lift through the second lifting assembly, the storage tank can be lifted to a preset height according to actual processing requirements, so as to facilitate the pipeline connection between the temporary storage tank and other equipment.

[0088] In this embodiment, the second lifting assembly may further include a fixing part 320, which is fixed on the ground or the vehicle body.
