Vacuum coupling steam enzyme deactivation drying device with solar auxiliary heat pump for flos chrysanthemi

Abstract

The invention discloses a vacuum coupling steam enzyme deactivation drying device with a solar auxiliary heat pump for flos chrysanthemi. The vacuum coupling steam enzyme deactivation drying device comprises a solar hot-water system, a heat pump system, a vacuum system, a steam enzyme deactivation system, a control system, a spiral tube heat exchanger, a gas heater and a gas drying tower, whereinthe heat pump system, the vacuum system and the steam enzyme deactivation system shares the same drying box. The vacuum coupling steam enzyme deactivation drying device can be used for forming the advantage complementary integration of two methods of solar auxiliary heat pump drying and vacuum drying; the drying processes of the saturated steam enzyme deactivation, the heat pump drying, the softening and the vacuum drying of the flos chrysanthemi are realized; meanwhile, essential oil volatilized in the drying procedure of the flos chrysanthemi is recovered. The vacuum coupling steam enzyme deactivation drying device is energy-saving and high-efficiency, is uniform in drying and has no microbial contamination; a dried product of the flos chrysanthemi is high in quality; the visual real-time monitoring can be realized and the economic value of the flos chrysanthemi is furthest utilized.

Description

technical field [0001] The invention relates to a drying device, which belongs to the technical field of plant processing, and in particular to a drying device for chrysanthemums assisted by a solar energy-assisted heat pump in vacuum coupling with steam. Background technique [0002] Chrysanthemum (Chuju Chrysanthemum morifolium) is the inflorescence head of the genus Chrysanthemum in the family Asteraceae. It is used as tea or medicine after drying. It is a characteristic agricultural product in Anhui Province and has passed the certification of China's famous brand agricultural products and geographical indication products. [0003] Chrysanthemum often adopts natural drying, hot air drying, microwave drying and other methods. Chrysanthemum is a heat-sensitive material. During processing, volatile components are easily lost and flavonoids are easily oxidized. The natural drying method is simple and easy, but the required drying time is too long, and it is easily restricte...
