[0026] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Please refer to Figures 1-4 , the present utility model provides a preheating tank for dairy product production, including:

[0028] A rapid heating chamber 1, one end of the top of the rapid heating chamber 1 is fixedly connected with a feed hopper 101, and a heating element 102 is fixedly connected to the inner top of the rapid heating chamber 1.

[0029] A stirring chamber 2, a connecting pipe 201 is fixedly connected between the stirring chamber 2 and the rapid heating chamber 1, a feeding pipe 202 is fixedly connected to one side of the outer wall of the stirring chamber 2, and an electric heating plate 203 is fixedly connected to the inner side wall of the stirring chamber 2.

[0030] A heat preservation chamber 3, a double-shaft motor 301 is fixedly connected between the top of the heat preservation chamber 3 and the stirring chamber 2. The two drive shafts of the double-shaft motor 301 respectively penetrate through the stirring chamber 2 and the heat preservation chamber 3 and are fixedly connected with a first rotating shaft 4 and a second rotating shaft 5. A stirring blade 9 is fixedly connected to the outer side wall of the first rotating shaft 4, and a stirring rod 10 is fixedly connected to the outer side wall of the second rotating shaft 5.

[0031] Among them, four columns 17 are fixedly connected between the stirring chamber 2 and the heat preservation chamber 3. The four columns 17 are evenly distributed on the top edge of the heat preservation chamber 3, which is convenient for supporting and positioning the stirring chamber 2 and ensuring the stability of the components in the stirring chamber 2 during operation.

[0032] In this embodiment, four groups of stirring rods 10 are provided. The four groups of stirring rods 10 are evenly distributed in a ring on the outer wall of the second rotating shaft 5. Each group of stirring rods 10 has four. The intervals between adjacent two stirring rods 10 are equal from top to bottom. By rotating a plurality of stirring rods 10, it is convenient to ensure the fluidity of the dairy product and prevent a film from forming on the surface of the dairy product.

[0033] In this embodiment, detachable top covers 14 are provided on the tops of the rapid heating chamber 1, the stirring chamber 2, and the heat preservation chamber 3. After unscrewing the detachable top covers 14, it is convenient to clean the interiors of the rapid heating chamber 1, the stirring chamber 2, and the heat preservation chamber 3, prevent the remaining dairy products inside from deteriorating, and cause pollution to subsequent production.

[0034] A filter screen 6 is provided at the outer side wall of the first rotating shaft 4 near the bottom. A mounting seat 7 is fixedly connected to the inner side wall of the stirring bin 2. The bottom edge of the filter screen 6 is fixedly connected with a connecting ring 8. The filter screen 6 is sleeved on the outer side wall of the first rotating shaft 4 and the connecting ring 8 is threadedly connected to the top of the mounting seat 7, which is convenient for filtering the solid matter of the dairy products in the stirring bin 2.

[0035] A feeding component 11 is jointly arranged between the stirring bin 2 and the heat preservation bin 3. The feeding component 11 includes a feeding valve 111 fixedly connected to the bottom of the stirring bin 2 and a liquid inlet pipe 112 fixedly connected to the top of the heat preservation bin 3. A transfer hose 113 is jointly threadedly connected between the feeding valve 111 and the liquid inlet pipe 112. Both ends of the transfer hose 113 can be detached from the feeding valve 111 and the liquid inlet pipe 112 respectively, which is convenient for maintenance.

[0036] An auxiliary heating cavity 12 is arranged on the outer wall of the heat preservation bin 3. A discharge valve 13 is arranged at the bottom of the heat preservation bin 3. An electric heating coil 15 is fixedly connected inside the auxiliary heating cavity 12. A heat conducting medium 16 is arranged inside the auxiliary heating cavity 12. The electric heating coil 15 is convenient for heating the heat conducting medium 16, and the temperature is maintained through the heat conducting medium 16, so that the temperature in the heat preservation bin 3 remains constant, and the dairy products are always kept in a heated state before discharging.

[0037] During use, first connect the heating element 102, the electric heating plate 203, the double-shaft motor 301 and the electric heating coil 15 to an external power supply and start them. The heating element 102 is an electric heating coil.

[0038] During operation, the dairy products are poured into the quick heating bin 1 from the feeding hopper 101. Since the volume of the quick heating bin 1 is limited and the heat is concentrated, the dairy products can be quickly heated by the heating element 102. After heating, the dairy products gradually flow into the stirring bin 2 along the connecting pipe 201.

[0039] The inner diameter of the connecting pipe 201 can be correspondingly set according to the actual heating rate of the dairy products. When the dairy products cannot reach a certain preset temperature during the feeding process, the connecting pipe 201 needs to be replaced and its inner diameter size needs to be reduced to reduce the feeding speed of the dairy products. On the contrary, the inner diameter size of the connecting pipe 201 can be correspondingly increased to increase the feeding speed.

[0040] The electric heating plate 203 on the inner wall of the stirring bin 2 has been started before, and can continuously heat the dairy products in the stirring bin 2. Starting the double-shaft motor 301 can drive the first rotating shaft 4 and the second rotating shaft 5 to rotate at the same time. The first rotating shaft 4 drives the stirring blades 9 to rotate, which is convenient for stirring the dairy products. The auxiliary materials for producing the dairy products can be added through the feeding pipe 202 and gradually mixed with the dairy products along with the stirring.

[0041] Since the dairy products already have a certain temperature when entering the mixing bin 2 and are constantly heated by the electric heating plate 203, after adding the auxiliary materials, the two can be quickly mixed. After a period of time, just open the feeding valve 111 to discharge the mixed dairy products through the connecting hose 113 into the heat preservation bin 3. Moreover, some solid impurities that are inevitably generated when the dairy products are mixed can be filtered down by the filter screen 6, ensuring that the dairy products entering the heat preservation bin 3 are uniform and delicate.

[0042] An electric heating coil 15 is embedded in the inner wall of the heat preservation bin 3. By heating the heat conduction medium 16, after its temperature rises to a certain level, the temperature inside the heat preservation bin 3 can be kept stable. And with the stirring of multiple stirring rods 10, it is convenient to ensure the sufficient fluidity of the dairy products, effectively preventing the formation of a layer on the surface of the dairy products to form a dairy product film, thereby ensuring the discharging quality of the dairy products, and finally discharging the liquid through the discharging valve 13.

[0043] In this device, the heating temperatures of the heating element 102, the electric heating plate 203, and the electric heating coil 15 decrease in sequence. The heating element 102 is used to raise the temperature of the dairy product raw materials in a short time. The electric heating plate 203 is used to ensure the temperature during the mixing and stirring of the dairy products. The temperature of the electric heating coil 15 does not need to be too high, and its function is to ensure the fluidity of the dairy products and prevent caking.

[0044] When the production of the dairy products is completed, each chamber is cleaned. Under the heating effects of the heating element 102, the electric heating plate 203, and the electric heating coil 15, the caking speed of the dairy products on the inner wall of the chamber can be delayed to a certain extent, which is more conducive to cleaning the dairy products. At the same time, after cleaning, the remaining heat can be used to dry the damp inner wall. During the drying period, the connecting hose 113 can be disconnected to facilitate drainage.

[0045] Although the present utility model has been described above with reference to the embodiments, however, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
