Problems solved by technology

At this stage, the heat energy provided by the steam cannot quickly and timely supplement the cooling caused by the induced wind. Once the temperature of the drying room cannot be kept between 35-40°C, the humidity can often reach 70% at this stage, which will cause the rose corolla and rosebuds to bloom. The color changes from bright and bright to brown and loses luster, which will cause a great loss of anthocyanins and reduce the nutritional and health effects of roses on the human body; second, because steam is used as a heat source, it is necessary to install a boiler to provide rose drying equipment. Water vapor, large investment in equipment, long construction period and high operating costs

Abstract

The invention discloses equipment for low-temperature drying of roses and a method using the equipment to dry the roses. The equipment comprises a drying box body, a moving trolley arranged in the drying box body, a dehumidifying and heat exchanging device arranged in the middle of the top in the drying box body, and a heat supply device for supplying heat to the drying box body. The problems of decrease of temperature and increase of humidity in the drying box body due to the fact that heat energy provided by steam at a stage of rose drying and color fixing cannot be quickly and timely supplemented for air inducing and dehumidifying are solved; the roses dried by the equipment are purplish red in color and bright in tinct, anthocyanin in the roses is protected, and nutrition and healthcare efficacy of the roses on human bodies is improved; the equipment is small in investment, low in running cost and convenient for popularization and use.

Description

technical field [0001] The invention relates to the field of rose drying production technology, in particular to a device and method for drying roses at low temperature. Background technique [0002] Roses are rich in color, and their pigments belong to polyphenolic compounds. It is a food with health effects officially approved by my country. The content of anthocyanins in roses is very high. Free anthocyanins are extremely rare under natural conditions. Existing in the form of glycosides, anthocyanins often form anthocyanins with one or more glucose, rhamnose, galactose, arabinose, etc. through glycosidic bonds. Anthocyanins are a class of compounds formed by combining anthocyanins and sugars with glycosidic bonds. They are flavonoids—a group of compounds that can appear red in a class of substances based on flavone cores. Due to their unique functionality, they are known as It is used to remove free radicals in the human body, proliferate lutein, anti-tumor, anti-cancer, ...
