Description

Technical Field

[0001] The utility model relates to the technical field of peony seed processing, and more specifically, to a peony seed drying device. Background Art

[0002] Peony seed oil is a woody nut plant oil extracted from peony seed kernels. It has a high content of unsaturated fatty acids and linolenic acid, and has unique effects such as anti-aging, longevity, and activation of peripheral nerves. It has preventive and improving effects on cardiovascular and cerebrovascular diseases, cancer prevention and treatment, anti-radiation, vision protection, and intelligence enhancement. It also has the effect of eliminating pigmentation spots, reducing wrinkles, and making the skin delicate and smooth.

[0003] In the process of processing peony seed oil, it is necessary to fry and dry the peony seeds in the early stage to ensure the oil yield. In the actual production process, since the peony seeds themselves are very different from conventional oil-pressing raw materials, when the peony seeds are fried and dried using conventional drying equipment, it will have a great impact on the later processing of the peony seed oil and the quality of the peony seed oil. For example, if the temperature of frying and drying the peony seeds is too high or too low, it will directly affect the content of unsaturated fatty acids and linolenic acid in the peony seed oil. In addition, if the peony seeds are contaminated during the operation process during frying and drying, it will inevitably increase the difficulty of the decolorization and deodorization processes of the finished oil in the later stage.

[0004] In existing drying devices, the hot air from the exhaust port is directly discharged into the atmosphere. The hot air discharged from the exhaust port often carries a certain amount of heat. Directly discharging it into the environment will not only cause energy waste, but also may cause certain thermal pollution to the environment. For example, patent No. CN202222419240.8 discloses a peony seed drying device for peony seed oil processing. In this device, the exhaust port directly discharges hot air into the environment, causing energy waste and environmental pollution. Utility Model Content

[0024] Figure 1 A peony seed drying device of the utility model is shown, comprising a drying box 2, a heat generator 1 connected to the drying box 2, a plurality of exhaust ports 9 are provided on one side of the drying box 2, and each exhaust port 9 is connected to an air inlet Ⅰ3 of the heat generator 1 through a hot air recovery component.

[0025] Working principle:

[0026] First, the heat generator 1 starts working, and the heat generator 1 generates heat and transfers it to the drying box 2. The peony seeds are heated and dried by the circulation of hot air inside the drying box 2. During the drying process, the moisture in the peony seeds gradually evaporates, so that the peony seeds reach the desired degree of dryness.

[0027] At the same time, an exhaust port 9 is provided on one side of the drying box 2. During the drying process, as the moisture of the peony seeds evaporates, moisture and waste heat will be generated inside the drying box 2. If these moisture and waste heat are not discharged in time, the drying efficiency will be reduced, and even the quality of the peony seeds will be affected. Therefore, the exhaust port 9 can discharge moisture and waste heat out of the drying box 2 in time to keep the inside of the drying box 2 dry and at a suitable temperature. The exhaust port 9 is connected to the air inlet Ⅰ3 of the heat generator 1 through a hot air recovery component. The exhausted hot air is not directly discharged to the outside, but is recovered and processed by the hot air recovery component. The hot air recovery component can capture part of the heat in the exhausted hot air, reintroduce it into the air inlet end of the heat generator 1, and preheat the cold air at the air inlet end, and reuse it in the drying process.

[0028] Through this hot air recovery method, the utility model realizes efficient use of energy. On the one hand, the recovered heat reduces the demand of the heat generator 1 for external energy, reducing energy consumption and cost; on the other hand, it reduces the emission of waste heat, which is conducive to environmental protection and sustainable development.

[0029] In the above scheme, the hot air recovery device includes: a heat recovery pipe 4, a condenser 5 arranged on the heat recovery pipe 4; a fan 6 arranged on the heat recovery pipe 4 at the exhaust port 9; wherein the two ends of the heat recovery pipe 4 are respectively connected with the exhaust port 9 and the air inlet Ⅰ3 of the heat generator 1. With this technical method, firstly, the two ends of the heat recovery pipe 4 are respectively connected with the exhaust port 9 of the drying box 2 and the air inlet Ⅰ3 of the heat generator 1, forming a closed circulation loop. In this way, the hot air containing heat energy and humidity discharged from the drying box 2 can be effectively recovered and reused through the heat recovery pipe 4. When the humid air containing heat energy is discharged from the exhaust port 9, it will first pass through the heat recovery pipe 4. At this time, the condenser 5 arranged on the heat recovery pipe 4 starts to work. The main function of the condenser 5 is to reduce the temperature in the hot air, so that the water vapor therein is condensed into liquid water, thereby realizing the removal of humidity in the hot air. At the same time, the condensation process will also release part of the latent heat, which can also be recovered and utilized. Then, the temperature and humidity of the hot air after being processed by the condenser 5 are effectively controlled, and it will continue to flow to the fan 6. The fan 6 is arranged on the side of the heat recovery pipe 4 located at the exhaust port 9. Its function is to provide power for the flow of hot air, ensure that the hot air can smoothly enter the heat recovery pipe 4, and enter the air inlet Ⅰ3 of the heat generator 1 after being processed by the condenser 5.

[0030] In the above scheme, the drying box 2 is symmetrically provided with multiple layers of snap-in grooves 7 on the inner side walls opposite to each other, and a partition plate 8 is installed on each layer of snap-in grooves 7. The drying box 2 is provided with multiple air inlets II 10 corresponding to the exhaust port 9 on the side wall opposite to the exhaust port 9, and each air inlet II 10 and each exhaust port 9 are constructed above the corresponding partition plate 8 to obtain a wind passage for drying. With this technical method, firstly, by symmetrically providing multiple layers of snap-in grooves 7 on both sides of the drying box 2, and installing partition plates 8 on these snap-in grooves 7, the interior of the drying box 2 can be divided into multiple independent spaces. In this way, the peony seeds can be placed in layers during the drying process, and the peony seeds between each layer can obtain uniform heat distribution, thereby avoiding the problem of uneven drying that may occur in the traditional drying method. Secondly, the provision of the partition plate 8 not only contributes to the uniformity of heat distribution, but also prevents the peony seeds from sticking to or piling up each other during the drying process, thereby ensuring the looseness and air permeability of the peony seeds. In this way, the hot air can better penetrate the peony seed layer, improve the heat transfer efficiency, and thus speed up the drying speed. In addition, the position design of the air inlet II10 and the exhaust port 9 opened on the other side of the drying box 2 is also very critical. The air inlet II10 is used to introduce hot air, while the exhaust port 9 is used to discharge moisture and waste heat. An air passage is formed between each air inlet II10 and the corresponding exhaust port 9, which can ensure that the hot air can form an effective circulation flow when flowing through the peony seed layer, thereby improving the utilization rate of heat.

[0031] The above scheme also includes: an air collecting hood 11 arranged at the exhaust port 9, each exhaust port 9 is connected to the heat recovery pipe 4 through the air collecting hood 11; wherein, an isolation net 12 is arranged on the air collecting hood 11 and the heat recovery pipe 4. With this technical method, the setting of the air collecting hood 11 increases the collection area at the exhaust port 9, so that the hot air can be more fully collected and introduced into the heat recovery pipe 4. At the same time, the air collecting hood 11 can also play a certain buffering and rectifying role, making the hot air more stable during the flow process and reducing energy loss. The setting of the isolation net 12 plays a key filtering role. During the drying process, peony seeds may release tiny particles, debris or other impurities. If these impurities enter the heat recovery system, they may block the pipeline, damage the equipment or reduce the heat recovery efficiency. By setting the isolation net 12 on the air collecting hood 11 and the heat recovery pipe 4, these impurities can be effectively intercepted to prevent them from entering the heat recovery pipe 4.

[0032] In the above scheme, a sealed door 13 is installed on the front of the drying box 2, and a transparent observation mirror 14 is provided in the middle of the sealed door 13. With this technical method, first, the setting of the sealed door 13 ensures the airtightness of the drying box 2. During the drying process, it is necessary to keep the temperature and humidity inside the drying box 2 stable to ensure the drying effect of the peony seeds. The sealed door 13 can effectively isolate the outside air and prevent the loss of heat and humidity, thereby improving the drying efficiency. At the same time, the sealed door 13 can also prevent dust, impurities, etc. from entering the drying box 2 to ensure the cleanliness of the drying environment. Secondly, the setting of the transparent observation mirror 14 enables the operator to observe the situation inside the drying box 2 in real time. Through the observation mirror, the operator can clearly see the drying state of the peony seeds, including color, humidity, etc., so as to judge the drying progress and effect. This helps the operator to adjust the drying parameters, such as temperature, humidity, etc., in time to optimize the drying effect. At the same time, the observation mirror can also help the operator to find abnormal conditions in time, such as adhesion and burning of peony seeds, so as to deal with them in time and avoid losses. In addition, the transparent observation mirror 14 is usually made of high temperature resistant and corrosion resistant materials to ensure that it can operate stably for a long time during the drying process. At the same time, the cleaning and maintenance of the observation mirror is relatively simple, and only needs to be wiped regularly to maintain its clarity.

[0033] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
