Rose drying equipment and method

Abstract

The invention discloses rose drying equipment and a method. The rose drying equipment comprises a rose shaping, color fixing and drying device, a rose microwave heating, sterilization and drying device and a rose steam condensation device, and further comprises a gas cyclic heating and drying rose device; the gas cyclic heating and drying rose device comprises a drying box; a rose drying chamber is mounted in the drying box; a support arm is mounted on the top wall of the rose drying chamber; and 10-12 inner circulation heat supply fans arranged on the support device are heating devices for heating the rose drying chamber and rose moisture collecting condensation devices. The rose drying equipment shortens the drying time of rosebuds and rose corollas, improves the drying efficiency, keeps the natural color and the luster of roses, can enable the dried rosebuds and rose corollas to reach consistent inner and outer colors, improves the quality and the grade of the rosebuds and the rose corollas, and improves natural nutritional ingredients and aroma of byproducts-rose cell sap.

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. Background technique [0002] The equipment and method for drying roses refer to the equipment and method for drying rose buds or rose corollas. At present, the drying process of rose buds and rose corollas mostly adopts low-temperature box-type drying method. Generally, steam or heat transfer oil is used as a heat source, and an oven is used to dry rose buds and rose corolla at low temperature. The equipment for drying rose buds and rose corollas uses hot air to heat and dry rose buds and rose corollas according to the principles of convection, conduction and radiation. It is gradually dried from the outside of rose buds and rose corollas inwards. The method is not conducive to the distribution of water contained in rose buds and rose corolla. The accumulation of water in rose buds and rose corolla in the flower center will e...

Problems solved by technology

At present, the drying process of rose buds and rose corollas mostly adopts low-temperature box-type drying method. Generally, steam or heat transfer oil is used as a heat source, and an oven is used to dry rose buds and rose corolla at low temperature. The equipment for drying rose buds and rose corollas uses hot air to heat and dry rose buds and rose corollas according to the principles of convection, conduction and radiation. It is gradually dried from the outside of rose buds and rose corollas inwards. The method is not conducive to the distribution of water contained in rose buds and rose corolla. The accumulation of water in rose buds and rose corolla in the flower center will easily cause oxidative browning of the flower center and loss of pigment. Generally, it is dried rose buds and rose corolla. The color is red, and the flower center is black or brown, which causes the color of the rose buds and rose corolla to be inconsistent inside and outside after drying, and cannot maintain the true color and luster of rose buds and rose corolla, reducing the nutrition and quality of rose buds and rose corolla; at the same time The existing low-temperature box-type drying equipment for rose buds and rose corollas takes a long time to dry and has low drying efficiency. In particular, it takes more than 30 hours to dry rose buds and rose corollas with steam, heat transfer oil and heat pump at low temperature; In addition, most of the drying rooms of the existing low-temperature box-type drying rose buds and rose corolla equipment are not equipped with rose cell liquid steam condensers, but directly set up a number of dry rose moisture exhaust outlets to dry the roses. The moisture containing the aroma of roses generated during the drying process is directly discharged into the air; or a rose cell liquid steam condenser is installed on the drying room, and the tide outlet of the rose cell liquid steam condenser is also directly discharged into the air. Moisture with rose aroma is emitted into the air, resulting in the waste of rose aroma substances and the loss of rose cell sap aroma substances in by-products; at the same time, it also causes rose essential oil, vitamin C, and flower color contained in rose buds and rose corolla. The loss of glycosides, flavonoids, and rose polyphenol nutrients reduces the quality and quality of rose buds and rose corollas
