Problems solved by technology

At present, the drying process of rose buds, rose corollas and rose petals mostly adopts low-temperature box drying method, which uses steam or heat transfer oil as the heat source, and uses an oven to dry rose buds, rose corollas and rose petals at low temperature, but this type of Low-temperature box-type drying equipment for rose buds, rose corollas and rose petals is gradually dried from the outside of rose buds, rose corollas and rose petals to the inside, which is not conducive to the distribution of moisture contained in rose buds, rose corollas and rose petals , the drying time is long, and the drying efficiency is low, especially the use of steam, heat transfer oil and heat pump to dry rose buds and rose corolla at low temperature takes more than 30 hours to dry; and the rose buds, rose corolla and rose corolla after low-temperature drying The color of the petals is prone to oxidative browning to reddish brown, which cannot maintain the true color and luster of rose buds, rose corollas and rose petals. The loss of nutrients such as energy, protein and carbohydrates contained in rose buds, rose corollas and rose petals; dried rose buds, rose corollas and rose petals also contain a certain amount of rose wax, using rose buds, rose corollas and rose petals When the petals are made into tea, people will feel astringent and have an earthy smell

Abstract

The invention discloses equipment and a method for drying roses at a low temperature in a circulating mode. The equipment for drying roses at the low temperature in the circulating mode comprises a microwave generating device, a rose shaping, color-fixing and drying device, a rose microwave heating, sterilizing and drying device and a rose radiating, dehumidying and discharging device, and further comprises a removal device, a temperature and humidity detecting control device and a detecting control device; the removal device is used for removing hot air generated during operation of a microwave waterproof isolating device, a rose steam condensing device and the microwave generating device; the temperature and humidity detecting control device is used for detecting and controlling the rose shaping, color-fixing and drying device, the rose microwave heating, sterilizing and drying device, and the rose radiating, dehumidying and discharging device; and the detecting control device is used for detecting and controlling operation speed of a chain plate. According to the equipment disclosed by the invention, rose drying time is shortened, rose drying efficiency is improved, natural color and gloss of roses are kept, and color of dried rose flower buds and dried rose crowns is internally and externally consist; and moreover, loss of energy, proteins and carbohydrate nutritional ingredients contained in roses further can be reduced, and rose wax can be removed.

Description

technical field [0001] The invention relates to the technical field of rose drying production, in particular to a device and method for drying roses in a low-temperature cycle. Background technique [0002] Roses are bright in color and have high medicinal value and economic value. Studies have shown that the nutrients contained in roses include: flavonoids, organic acids, phenols, tannins, alkaloids, sugars, amino acids and proteins and more. It is a kind of mineral elements, and is rich in energy and carbohydrates; its main physiological function is to resist oxidation and free radicals, protect the cardiovascular and central nervous system, and has been widely used in food, health care products, cosmetics, medicine and other industries. In recent years, dried roses, that is, dried rose buds, rose corollas, and rose petals as substitute teas, are popular in domestic and foreign markets. At present, the drying process of rose buds, rose corollas and rose petals mostly adop...
