DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0022] Example Please refer to Figure 1 and Figure 2 The present embodiment provides a horizontal tea seed powder steaming device, comprising a steaming drum 10, an auger 20 and a steam generator. The steam generator and its connecting components are common industrial devices, which are not shown in the figure, but this does not affect the understanding of the present invention by those skilled in the art.

[0023] In this embodiment, the steaming cylinder 10 has a long straight double-layer structure, and a hot steaming space 11 is formed inside the steaming cylinder. The diameter, length, thickness of the cylinder wall and other dimensions of the cylinder are determined according to the specific output and can be set to different specifications. The two ends of the steaming cylinder 10 are respectively provided with a feed port 12 and a discharge port 13, wherein the feed port 12 opens upward and is connected to a hopper 121, which is the entrance for introducing tea seed powder into the steaming cylinder 10. The feed port 12 is located at the left end of the steaming cylinder 10; the discharge port 13 opens downward and is located at the right end of the steaming cylinder 10.

[0024] The steam drum 10 is also provided with a steam inlet 14 and a steam outlet 15. The steam inlet 14 is connected to the outer wall of the steam drum 10, and the steam outlet 15 is connected to the inner wall of the steam drum 10. The steam inlet 14 and the steam outlet 15 are both located at the rear end of the steam drum 10. The inner wall of the steam drum 10 is provided with an air hole 16. The air hole 16 connects the interlayer and the hot steaming space 11 inside the steam drum 10, and is a passage for hot steam to enter the hot steaming space 11. The steam outlet 15 is located on the right side of the jacket, and its purpose is to allow the steam to be discharged to the right end, which can prevent the powder at the feeding end from being stuck with the auger 20.

[0025] As a further improvement, the pores 16 are distributed at the lower part of the inner wall of the steaming drum 10. For example, in the present embodiment, seven pores 16 are drilled at intervals, and the seven pores 16 are arranged circumferentially along the inner wall of the steaming drum 10. The entire inner wall is provided with multiple pores 16 to ensure that the steam can enter the steaming drum 10 from between the interlayers. When the tea seed powder is transported in the steaming drum 10, it does not fill the entire hot steaming space 11, but is concentrated in the lower part of the steaming drum 10. Therefore, the position of the openings on the inner wall of the steaming drum 10 should not exceed 1 / 3 of its height. If the position of the openings is too high, the material cannot cover all the openings, which will cause a large amount of steam to escape from the position without material coverage (the pressure at the position without material coverage is relatively small and the steam is easier to pass), and the hot steaming effect cannot be achieved. In the present embodiment, the pores 16 are opened at the lower part of the inner wall, and the material can completely cover the pores 16. When the steam enters the hot steaming space 11, it is fully in contact with the tea seed powder, which is conducive to ensuring the hot steaming effect.

[0026] In this embodiment, the auger 20 is connected to a driving mechanism 30 and is disposed in the steaming drum 10 to push the tea seed powder forward. The auger 20 has a rotating shaft 21 and a spiral blade 22 connected to the surface of the rotating shaft 21. The auger 20 rotates under the drive of the driving mechanism 30, and the spiral blade 22 drives the tea seed powder forward.

[0027] Furthermore, the rotating shaft 21 of the auger 20 is connected between the front and rear walls of the steam drum 10 through a bearing, and the auger 20 is coaxially arranged with the steam drum 10 .

[0028] Specifically, the driving mechanism 30 in this embodiment is a motor, which is directly connected to the end of the rotating shaft 21 of the auger 20 through a coupling. This direct connection has the advantages of compact structure, high sensitivity and high transmission efficiency. Of course, in some other embodiments, a belt or chain transmission connection can also be used.

[0029] Furthermore, the helix angle of the spiral blade 22 is set to 25°, the blade surface is polished, and the edge is rounded, so that the wet powdered material can be better transported and the sticking and clumping that cause the auger 20 to get stuck can be avoided, which can ensure both the transportation efficiency and the full contact between the tea seed powder and the steam.

[0030] In this embodiment, a steam generator is connected to the steam inlet 14 to provide hot steam. It should be noted that this embodiment does not limit the steam generator, and any steam generating device in the prior art can be used.

[0031] In this embodiment, the double-layer structure of the steam drum 10 is formed in this way: a jacket is arranged outside the middle and rear ends of the steam drum 10, and a hollow structure is formed between the jacket and the inner wall of the steam drum 10. The hollow structure is filled with hot steam during operation to form a hot zone; and the front end of the steam drum 10 is not provided with a jacket structure, so a cold zone is formed.

[0032] In this embodiment, the "cold zone" formed at the front end of the steaming cylinder 10 is separated from the "hot zone" formed at the middle and rear ends of the steaming cylinder 10. Since the material is transported from left to right, a large amount of steam is prevented from overflowing from the front end and causing the tea seed powder to clump and block the feed port 12; the discharge port 13 is located in the hot zone without a significant temperature difference, which can reduce the formation of condensed water and affect the moisture content of the material.

[0033] Furthermore, the installation setting of the steam drum 10 is lower on the left and higher on the right, with the best angle of 15° to the ground, so that the steam can be discharged from the right steam outlet 15 along the material transportation direction, further reducing the situation where the feed port 12 is blocked by tea seed powder clumping due to steam overflow.

[0034] Specifically in this embodiment, online moisture detectors 40 are installed at the front and rear ends of the steaming drum 10 to respectively detect the moisture content of the tea seed powder at the feed inlet 12 and the discharge outlet 13, and then determine the steaming effect.

[0035] Specifically in this embodiment, the side wall of the steam drum 10 is provided with two cleaning openings 17 , both of which are horizontally oriented and have a diameter slightly smaller than the inner diameter of the steam drum 10 , thereby facilitating cleaning of the interior of the steam drum 10 .

[0036] Specifically in this embodiment, a drain port 18 is provided below the front end of the steam drum 10, and the drain port 18 is connected to the outer wall of the steam drum 10 for draining the sewage between the interlayers. More specifically, the drain port 18 is connected to a steam trap 19 for draining condensed water.

[0037] Specifically, in this embodiment, an online temperature detector 50 is installed at the rear end of the steam drum 10 to detect in real time whether the internal temperature of the steam drum 10 meets the standard, and then adjust the corresponding working parts. Specifically, the motor of this embodiment is equipped with a frequency converter, which controls the material transportation speed and the steam volume of the steam generator by adjusting the auger speed, thereby achieving precise control of the moisture and temperature of the tea seeds.

[0038] It is worth mentioning that the steam drum 10 of this embodiment is in a high temperature state when in use. Therefore, a thermal insulation layer may be wrapped around the outside of the steam drum 10, such as a thermal insulation layer composed of thermal insulation cotton and aluminum foil, which can not only prevent people from being scalded, but also prevent heat loss in the hot steaming space, thereby reducing energy consumption.

[0039] In summary, the horizontal tea seed powder hot steaming device of the present invention is essentially steam heating, and the steam directly passes through the material with higher thermal efficiency. At the same time, part of the water in the steam can be steamed into the tea seed powder to adjust the water content of the tea seed powder and soften the cell wall of the tea seed. When the cell wall of the tea seed is softened, the oil is more easily squeezed out of the cell. Moreover, the appropriate water content can enable the tea seeds to form a good internal structure in subsequent processing, which is conducive to the flow and aggregation of oil, and is suitable for the traditional hot steaming-hydraulic pressing route.

[0040] By providing the steaming cylinder 10 and the auger 20, continuous hot steaming of tea seed powder can be achieved. In this process, the double-layer structure of the steaming cylinder 10 can ensure that the space between the inner and outer walls is always filled with hot steam, ensuring that the temperature of the hot steaming space 11 remains constant, and the air holes 16 opened on the inner wall allow the steam to smoothly enter the hot steaming space 11, and then fully contact with the tea seed powder and be absorbed, thereby ensuring the final hot steaming effect and meeting the needs of large-scale continuous production.

[0041] The steaming cylinder 10 of the present invention is provided with a "cold zone" and a "hot zone", which are separated from each other. Since the material is transported from left to right, a large amount of steam is prevented from overflowing from the front end and causing the tea seed powder to clump and block the feed port 12; the discharge port 13 is located in the hot zone without a significant temperature difference, which can reduce the formation of condensed water and affect the moisture content of the material, and further ensure the continuity of production.

[0042] Obviously, it is not necessary and impossible to list all the embodiments here, and the obvious changes or modifications derived therefrom still fall within the protection scope of the invention.
