Description

Technical Field

[0001] The utility model belongs to the technical field of extraction equipment, and particularly relates to a device for extracting the original juice of peony petals. Background Art

[0002] In the existing technology for extracting the original juice of peony petals, the commonly used method is to mix peony petals with water in a certain proportion, and then distill and condense by heating to 100 degrees Celsius to obtain the original juice of the petals. However, this traditional method has several significant deficiencies:

[0003] 1. High water content and difficult to store. The original juice of peony petals obtained by high-temperature distillation contains a large amount of water, which is not convenient for storing the juice and is prone to juice deterioration, affecting its quality and shelf life;

[0004] 2. During the high-temperature treatment process, some volatile components in peony petals are easily lost due to the thermal effect, which directly affects the aroma and taste of the final product, making it relatively weak;

[0005] 3. After high-temperature distillation treatment, the original form of peony petals is damaged, which not only affects the appearance of the petals but also limits their subsequent reuse value, such as being unable to be used for making flower tea.

[0006] Therefore, it is necessary to design a device for extracting the original juice of peony petals to solve the above technical problems. Summary of the Invention

[0007] To solve the above technical problems, the utility model provides a device for extracting the original juice of peony petals. By adopting the design of a vacuum oven and a ventilation valve, the evaporation process of peony petals can be carried out at 55 - 60 degrees Celsius, effectively reducing the water content, improving the storage stability of the juice, and at the same time reducing the loss of volatile components in peony petals, thereby enhancing the aroma and taste of the final product.

[0047] Working principle:

[0048] For the placement of peony petals, first, the peony petals are evenly placed in the storage chamber 30 of the carrier 3. The design of the carrier 3 ensures the stability of the peony petals during the extraction process, preventing the movement or damage of the peony petals. Through the adjustment unit, the distance between the covering plate 4 and the peony petals can be adjusted as needed. When evacuating, the movement of the peony petals is avoided. Start the vacuum oven 1 to create a vacuum environment. The temperature of the vacuum oven 1 is controlled at 55 - 60 °C, which helps to reduce the moisture content and improve the storage stability of the juice. The air exchange valve 10 controls the air exchange time. By exchanging air once every 3 - 5 minutes, the drying efficiency of the vacuum oven 1 and the speed of extracting the original juice of peony petals can be effectively improved, thereby improving the working efficiency of the entire device.

[0049] Heating and evaporation: The peony petals are heated in the vacuum oven 1, and the volatile components evaporate. This step utilizes the characteristic of low boiling point in the vacuum environment, effectively reducing the loss of volatile components of the peony petals.

[0050] Condensation and collection: The evaporated steam is condensed by the first condensing pipe 2 and the second condensing pipe 22 and finally collected in the collection bottle 6. At this time, the working environment of the first condensing pipe 2 and the second condensing pipe 22 is 0 °C. The spiral design of the first condensing pipe 2 and the second condensing pipe 22 enhances the condensation effect and improves the heat exchange efficiency. The inner diameter of the first condensing pipe 2 is larger than that of the second condensing pipe 22 because at the beginning, the gas has a large water content and is easy to condense. The connecting pipe 21 is set in a Y shape, and the inner diameter of the connecting pipe 21 is larger than that of the first condensing pipe 2 to prevent the condensed water from being pumped away.

[0051] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent changes and modifications made according to the scope of the present invention should still fall within the scope covered by the present invention.
