Problems solved by technology

The products obtained by traditional drying are generally reduced in size and hard in texture. Some substances are oxidized, most of some volatile components will be lost, some heat-sensitive substances will be denatured, and microorganisms will lose their biological vitality. Not easy to dissolve in water

Abstract

The invention discloses a method for processing Abelmoschus manihot. The method includes the steps that sorting is carried out; the Abelmoschus manihot is placed into a tray; the temperature is lowered gradually till the temperature is lower than the eutectic point temperature of the Abelmoschus manihot, and the Abelmoschus manihot is frozen for 6-10h at the temperature of -35DEG C to -40DEG C; vacuuming is carried out when the temperature reaches -40DEG C, and heating is carried out when the vacuum degree reaches 200-260Pa; the first step of heating is carried out, specially, the temperature is raised to -25DEG C from -40DEG C in 2h and kept for 1h when reaching -25DEG C, the temperature is raised to -10DEG C from -25DEG C in 2h and kept for 1h when reaching -10DEG C, the temperature is raised to 5DEG C from -10DEG C in 2h and kept for 1h when reaching 5DEG C, the temperature is raised to 20DEG C from 5DEG C in 2h and kept for 1h when reaching 20DEG C, the temperature is raised to 35DEG C from 20DEG C in 2h and kept for 1h when reaching 35DEG C, and the temperature is raised to 40DEG C from 35DEG C in 2h and kept for 1h when reaching 40DEG C; the second step of heating is carried out, specially, the temperature is kept ranging from 35DEG C to 40DEG C, and processed Abelmoschus manihot is discharged when the water content is less than 3%. An Abelmoschus manihot medicinal material prepared through the method has essential characteristics of fresh medicine, can keep medicinal properties of fresh traditional Chinese medicine for a long time, and is convenient to store and transport and suitable for industrial production and clinical use, and pharmaceutical effects can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of processing Chinese medicinal materials, in particular to a method for drying and processing Chinese medicinal material marshmallow flowers. Background technique [0002] Hollyhock flower is the corolla (with stamens and style) of Abelmoschus manihot (L.) Medic., a plant of Malvaceae. The first part of "Pharmacopoeia of the People's Republic of China" 2010 edition records: the dried flowers of hollyhock flower are often shrunken and broken, and the petals are triangular, broad and obovate, 7-10cm long and 7-12cm wide, with longitudinal veins on the surface, which are radial. Light brown, shallow wavy edges; inner base purple-brown. Stamens numerous, united into a tube, 1.5-2.5cm long, anthers subsessile. Stigma purple-black, spoon-shaped, 5-lobed. The gas is slightly fragrant, and the taste is sweet and light. Pick when the flowers bloom in summer and autumn, and fresh hollyhock flowers need to be drie...
