Description

Technical Field

[0001] This utility model relates to the field of fragrance processing, specifically a drying centrifuge. Background Technology

[0002] The drying process of spices is one of the key steps, and its core objective is to retain the aroma components, color and particle integrity of spices while efficiently removing moisture.

[0003] Existing centrifuges are typically equipped with filters and vibrators. Vibration is used to address the problem of clogging caused by uneven particle distribution, high viscosity, or high humidity of fragrance particles accumulating on the screen surface. However, current vibrators are usually adjusted manually by changing the vibrator parameters to a fixed value for the vibration frequency. Since the viscosity and humidity of fragrances in the same batch may vary before entering the centrifuge for separation, the clogging situation of the screen varies under a fixed vibration frequency. For example, when there are fragrances with different viscosities in the same batch, low-frequency vibration is insufficient to overcome the cohesive force and surface tension of the more viscous fragrance, resulting in the inability to remove residual material, requiring high-frequency, low-amplitude vibration. For the less viscous fragrance, high-frequency vibration may cause the particles to bounce excessively due to inertia, preventing them from effectively passing through the screen holes, requiring low-frequency, high-amplitude vibration.

[0004] Therefore, there is an urgent need for a drying centrifuge that determines the properties of fragrances by converting the clogging of the fragrance on the filter bag surface into changes in the weight of the attached material, and triggering a corresponding vibration frequency. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a drying centrifuge.

[0006] The objective of this utility model can be achieved through the following technical solutions: A drying centrifuge includes a sensing component comprising an annular pressure sensor and a control module. The annular pressure sensor is coaxially mounted below a filter element to detect a first weight and a second weight of the filter element. The control module is located outside the drying centrifuge and electrically connected to the annular pressure sensor. A vibrator is mounted on the lower part of the filter element and electrically connected to the control module. The annular pressure sensor feeds back the second weight change of the filter element to the control module to determine the fragrance properties, and the control module adjusts the vibration frequency of the vibrator.

[0007] Preferably, the second weight change of the filter element is the net weight of the fragrance attached.

[0008] Preferably, the control module includes a data module and a peeling module. The data module includes a data mapping table containing the characteristics of different spices and the corresponding required vibration values.

[0009] Preferably, the first weight change of the filter element is its own weight, and the tare module returns the first weight to zero.

[0010] Preferably, it also includes a central seat, which has a hollow structure and a material discharge chute on its upper side.

[0011] Preferably, the filter element includes a limiting mesh frame and a filter cloth. The limiting mesh frame is coaxially sleeved on the upper part of the central seat. Both the upper and lower parts of the limiting mesh frame are annular, and the filter cloth is sleeved inside the limiting mesh frame.

[0012] Preferably, the middle of the limiting mesh frame has a plurality of curved vibration strips arrayed. Preferably, the filter mesh is narrow at the bottom and wide at the top, and is fitted with the limiting mesh frame.

[0013] The beneficial effects of this utility model are as follows: the peeling module resets the first weight fed back to the control module by the annular pressure sensor to zero. In addition, the data module includes a data mapping table containing different fragrance characteristics and corresponding required vibration values. When the filter cloth intercepts the fragrance, the fragrance blockage on the filter cloth will increase the weight of the filter cloth. This increase is the second weight fed back to the control module by the annular pressure sensor. By comparing the value of the second weight with that of the data module, the change in weight data can be converted according to the blockage of the fragrance on the surface of the filter bag, thereby determining the fragrance properties and triggering the corresponding vibration frequency, thus solving the problem caused by the fixed vibration frequency.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Since the viscosity and humidity of spices in the same batch may be uneven before entering centrifuge 2 for separation, the clogging of the screen varies under a fixed vibration frequency. For example, when there are spices with different viscosity in the same batch, for spices with higher viscosity, low-frequency vibration is difficult to overcome cohesion and surface tension, resulting in the inability to remove the residue, and high-frequency micro-amplitude vibration is required. For spices with lower viscosity, high-frequency vibration causes the particles to bounce excessively due to inertia and cannot pass through the screen effectively, and low-frequency high-amplitude vibration is required.

[0018] refer to Figures 1-4 The drying centrifuge 2 shown includes a sensing component, which includes an annular pressure sensor 4 and a control module 22. The annular pressure sensor 4 is coaxially mounted below the filter element to detect the first weight and the second weight of the filter element. The control module 22 is located outside the drying centrifuge 2 and is electrically connected to the annular pressure sensor 4. A vibrator 7 is mounted on the lower part of the filter element and is electrically connected to the control module 22. The annular pressure sensor 4 feeds back the second weight change of the filter element to the control module 22 to determine the fragrance properties, and the control module 22 adjusts the vibration frequency of the vibrator 7.

[0019] Specifically, the drying centrifuge 2 is existing technology, comprising a base 1, a centrifuge 2, a central seat 3, and a filter element. The base 1 is a conical cylindrical structure supported by three cylinders at its edge. The central seat 3 is fixed to the bottom of the conical cylinder. The centrifuge 2 is fixed to the upper part of the base 1, and a feed inlet is located at the top of the centrifuge 2. Since the centrifuge 2 is existing technology, it will not be described in detail here. The filter element is located inside the base 1. The central seat 3 is a hollow structure, and the filter element is coaxially placed on the upper part of the central seat 3. The filter element surrounds the centrifugal outlet of the centrifuge 2, ensuring that all spices ejected from the centrifuge 2 outlet can contact the filter element for sieving. The filter element has a conical structure with an internal cavity. The bottom of the filter element is coaxial with the center seat 3, and several material discharge grooves are opened on the upper side of the center seat 3 to discharge fragrances that fail to pass through the filter element. Fragrances that pass through the filter element will collide with the inner wall of the conical cylinder of the base 1, causing the fragrances to slide down the inner wall. Fragrances that do not pass through the filter element fall through the material discharge grooves, while fragrances that pass through the sieve slide down the edge of the base 1. At the same time, a vibrator 7 is fixed on the side of the center seat 3. The vibrator 7 generates vibration when energized, and the vibration is transmitted to the filter element through the center seat 3, which can clear the fragrance that clogs the filter element, thereby maintaining the filtration quality stably over a long period of time.

[0020] Specifically, the filter element includes a limiting mesh frame 5 and a filter cloth 6. The limiting mesh frame 5 is coaxially sleeved on the upper part of the central seat 3. The upper and lower parts of the limiting mesh frame 5 are both annular, and several curved vibrating strips are arrayed in the middle. The filter cloth 6 is sleeved inside the limiting mesh frame 5. The filter cloth 6 is specifically sleeved on the upper and lower annular parts of the limiting mesh frame 5. Through several curved vibrating strips, the filter cloth 6 can be limited and the vibration of the vibrator 7 can be transmitted to the filter cloth 6. At the same time, several sets are evenly arrayed to make the filter cloth 6 vibrate evenly, so as to evenly shake off the fragrance that is blocked in the filter cloth 6. At the same time, the vibrator 7 can also transmit the vibration to the base 1 and the centrifuge 2 through the central seat 3, so that the entire base 1 and centrifuge 2 vibrate slightly, which can also accelerate the centrifugation efficiency of the fragrance.

[0021] More specifically, the bottom of the conical cylinder forms an upward slope along its axis. Two symmetrical arc-shaped grooves are also provided at the bottom of this slope, i.e., the bottom of the base 1. This design allows fragrances sliding down from the filter element to be quickly discharged through the slope, reducing accumulation inside the base 1. Additionally, a sensing component is provided, including a ring pressure sensor 4 and a control module 22. The control module 22 contains a peeling module and a data module. The ring pressure sensor 4 is fitted between the upper part of the central seat 3 and the limiting mesh frame 5. The weight of the limiting mesh frame 5 and the filter cloth 6 applied to the ring pressure sensor 4 constitutes the first weight. The ring pressure sensor 4 is electrically connected to the control module 22, which in turn is electrically connected to the vibrator 7. The peeling module... The first weight fed back to the control module 22 by the ring pressure sensor 4 is zeroed. This first weight is the weight of the limiting mesh frame 5 and the filter cloth 6. In addition, the data module includes a data mapping table, which contains different fragrance characteristics and the corresponding required vibration values. When the filter cloth 6 intercepts the fragrance, the fragrance blockage on the filter cloth 6 will increase the weight of the filter cloth 6. This increase is the second weight fed back to the control module 22 by the ring pressure sensor 4. The second weight is the data of the fragrance blockage, which is fed back to the control module 22. The value of the second weight is compared with that of the data module. Based on the change in the weight of the fragrance attached to the filter bag surface, the fragrance properties are determined to trigger the corresponding vibration frequency, thus solving the problem caused by the fixed vibration frequency.

[0022] Working principle: The fragrance enters through the feed inlet of centrifuge 2. Centrifugal force causes the fragrance to be thrown out and contact the filter cloth 6. Through the filter holes of the filter cloth 6, the fragrance is separated and sieved. The sieved fragrance collides with the inside of the base 1 and slides down the arc-shaped trough along the inner side of the base 1. The fragrance intercepted by the filter cloth 6 falls from the upper side of the central seat 3. Simultaneously, the vibrator 7 is activated, generating vibration. The vibration is transmitted through the central seat 3 to the limiting frame 5 and the filter cloth 6, causing the intercepted fragrance to vibrate and fall off. Additionally, the vibration of the central seat 3 also... The vibration is transmitted to the entire base 1 and centrifuge 2. When the filter cloth 6 intercepts a certain amount of fragrance, the intercepted fragrance applies weight to the limiting mesh frame 5, which in turn applies force to the annular pressure sensor 4. The net weight of the fragrance sensed by the annular pressure sensor 4 is fed back to the control module 22. The data module in the control module 22 performs a data mapping table comparison to determine the characteristics of the fragrance. At the same time, the control module 22 adjusts the vibration frequency of the vibrator 7 so that when the weight of the fragrance blocked by the filter cloth 6 is too heavy, the vibration frequency is increased, and when the weight of the fragrance blocked by the filter cloth 6 is light, the vibration frequency is decreased.
