Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a steam generating device for tea pressing production. Background Art

[0002] In the existing tea cake production, the softened tea raw materials are put into a cake press for pressing to complete the production of tea cakes. However, although the steam equipment in the existing cake pressing equipment is a commonly used equipment, it still cannot achieve fully automatic continuous operation during the production process, and has poor softening effect and is not easy to clean.

[0003] In view of this, it is extremely important to develop a steam generating device for tea pressing production with a reasonable structural design. Summary of the Invention

[0004] The purpose of the utility model is to provide a steam generating device for tea pressing production with high automation, convenient operation and excellent comprehensive performance to solve the above-mentioned existing technical problems.

[0005] To achieve the above technical solution, the technical solution of the utility model is as follows: A steam generating device for tea pressing production includes a heating cavity provided with a hollow interior. A disc-shaped hollow insulator is provided at the bottom of the heating cavity; a heating coil is spirally arranged inside the insulator; a steam pipe is provided at the top of the heating cavity, and the steam pipe is connected to a tea pressing fixture A and then connected to a blower; the air outlet end of the blower is connected to a tea feeding end B.

[0006] Among them: The heating coil heats the moisture inside the heating cavity into steam, and then softens the tea inside the tea pressing fixture along the steam pipe. The softened steam is guided by the blower to the tea feeding end to perform the first softening on the tea.

[0007] Further, the periphery of the heating cavity is wrapped with heat insulation cotton; a float valve is provided inside the heating cavity; a drain valve is provided at the bottom of the heating cavity, and a cleaning valve is obliquely arranged between the adjacent float valve and the drain valve; a pressure sensor is provided at the top of the heating cavity.

[0008] Further, the bottom inside the heating cavity is obliquely arranged; a temperature sensor is in surface contact with the top surface of the heating cavity.

[0009] Further, the insulator includes a detachable upper ceramic component and a detachable lower ceramic component, and a columnar installation cavity is formed between the adjacent ceramic component and the lower ceramic component; the heating coil is detachably installed on the installation cavity.

[0010] Further, the thickness of the upper ceramic component is 2 mm; the thickness of the lower ceramic component is 8 mm.

[0011] Furthermore, a second heating component is provided between the air outlet end of the blower and the tea feeding end, and the second heating component is a resistance wire heater.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1) During operation, as long as the heating coil is energized, eddy currents can be generated on the contact surface with the heating cavity to heat the water inside, generating water vapor. The water vapor is transported through the steam pipeline to the tea pressing fixture to perform the second and final softening heating on the tea in the tea pressing fixture, making the softening degree of the tea reach 99.9%. This ensures that when pressed into a cake shape, the tea in the tea pressing fixture will not be crushed into powder due to excessive dryness and cannot form a cake. During the whole process, since the steam generating device is always in the heating state, the water inside will decrease due to the water vapor. To prevent dry burning due to water shortage, a float valve is set to automatically replenish water to the steam generator to ensure that there is enough clean water in the steam generator, enabling the whole device to adapt to continuous production and improving production efficiency;

[0014] 2) After the steam of the present utility model enters the tea in the tea pressing fixture for the second and final softening heating, there is still residual heat. At this time, power is applied by the blower to make it pass through the second heating component for heating up and then guided to the tea feeding end to perform the first softening on the tea. In this way, not only can the speed of the second and final softening be accelerated, but also electric energy can be saved, and the overall production efficiency of pressing is further accelerated;

[0015] 3) The periphery of the steam tank of the utility model is wrapped with heat insulation materials to reduce heat dissipation and power loss; a float valve is set to automatically supplement water to the heating cavity to ensure no dry burning and improve service life. A drain valve is provided at the bottom of the heating cavity to discharge impurities such as water scale in the tank, prevent water scale attachment, improve the utilization of electric energy, enable it to adapt to continuous production, and improve production efficiency;

[0016] 4) The utility model connects the pipeline through the cleaning valve. Of course, cleaning agents can be directly added through the cleaning valve for cleaning, or it can be heated to a specified temperature and then the cleaning valve is connected to blow high-speed running water into it for washing, and finally discharged by the drain valve.

[0017] In summary, the device is convenient to use and control, has uniform air intake, and is stable and reliable in operation. It softens the raw materials through steam, improving the effect and efficiency of the cake pressing operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to enable those skilled in the art in this technical field to better understand the solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0022] Please refer to the attached Figure 1 As shown: A steam generating device for tea pressing production includes a heating cavity 1 provided with a hollow structure. A disc-shaped hollow insulator 2 is provided at the bottom of the heating cavity 1; a heating coil 3 is spirally arranged inside the insulator 2; a steam pipe 4 is provided at the top of the heating cavity 1. After the steam pipe is connected to the tea pressing fixture A and then connected to a blower 5; the air outlet end of the blower is connected to the tea feeding end B; specifically, the heating coil 3 heats the moisture inside the heating cavity 1 into steam, and then the steam softens the tea inside the tea pressing fixture A along the steam pipe 4. The softened steam is guided to the tea feeding end through the blower 5 to perform the first softening of the tea.

[0023] On the basis of the above embodiment, the periphery of the heating cavity 1 is wrapped with heat insulation cotton 11; a float valve 12 is provided inside the heating cavity 1; a drain valve 13 is provided at the bottom of the heating cavity 1; a cleaning valve 14 is obliquely arranged between the adjacent float valve 12 and drain valve 13; a pressure sensor 15 is provided at the top of the heating cavity 1.

[0024] When this example works, as long as the heating coil is powered on, eddy currents can be generated on the contact surface with the heating chamber to heat the water inside, generating water vapor. The water vapor is transported through the steam pipeline to the tea pressing fixture to perform the second and final softening heating on the tea in the tea pressing fixture, making the softening degree of the tea reach 99.9%. This ensures that when the tea is pressed into a cake shape, it will not be crushed into powder due to the over-dry tea in the tea pressing fixture and cannot form a cake shape. During the whole process, since the steam generating device is always in the heating state, the water inside will decrease due to the water vapor. To prevent dry burning due to water shortage, a float valve is set to automatically replenish water for the steam generator to ensure that there is enough clean water in the steam generator, enabling the whole device to adapt to continuous production and improving production efficiency.

[0025] Based on the above embodiment, the bottom inside the heating chamber 1 is inclined, which is convenient for cleaning all the impurities inside during subsequent cleaning; a temperature sensor is in contact with the top surface of the heating chamber 1 to detect the temperature during operation.

[0026] Based on the above embodiment, the insulator 2 includes a detachable upper ceramic component 21 and a lower ceramic component 22. A columnar installation cavity is formed between the adjacent ceramic components 21 and the lower ceramic component 22; the heating coil 3 is detachably installed on the installation cavity.

[0027] Based on the above embodiment, the thickness of the upper ceramic component 21 is 2 mm; the thickness of the lower ceramic component 22 is 8 mm.

[0028] Based on the above embodiment, a second heating component is provided between the air outlet end of the blower and the tea feeding end, which is used to simply heat the cooled steam and then perform the first softening on the tea. Specifically, there is still residual heat after the steam enters the tea in the tea pressing fixture for the second and final softening heating. At this time, power is applied by the blower to make it pass through the second heating component for heating up and then guided to the tea feeding end to perform the first softening on the tea. In this way, not only can the speed of the second and final softening be accelerated, but also electric energy can be saved, and the overall production efficiency of pressing is further accelerated. The second heating component is a resistance wire heater.

[0029] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art should be able to make equivalent embodiments with some changes or modifications using the above-disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
