Embodiment 1

[0023] Weigh 300kg of Rehmannia glutinosa, rinse it with clean water, visually check that no sediment flows out, put it into a steamer, continuously feed saturated water vapor, and steam at a temperature of 100°C. After steaming for 1 hour, start to collect the rehmannia juice produced, stop steaming for 3 hours, cool down to 60°C, put clean stones in the steamer to press the rehmannia, adjust the amount of stones, and ensure that the pressure of the rehmannia is 2kpa. After keeping squeezing for 30 minutes, take out the stone, inject saturated steam again, control the temperature at 100°C, continue steaming for 4 hours, and collect the resulting rehmannia juice. Merge the rehmannia juice collected twice, heat and concentrate to 60kg. Dry the steamed Rehmannia glutinosa at 55°C for 8 hours at low temperature, add the concentrated rehmannia juice, mix well, cover and suffocate for 12 hours, and then dry at 60°C for 48 hours to obtain the finished rehmannia glutinosa.

Embodiment 2

[0029] Weigh 300kg of Rehmannia glutinosa, wash it with clean water, and visually check that no sediment flows out, put it into a steamer, continuously inject saturated water steam, and steam at a temperature of 98°C. Begin to collect the rehmannia glutinosa juice that produces after 1 hour, stop feeding steam in 3 hours. Cool down to 60°C, put a clean stone in the steamer, press the rehmannia glutinosa with a pressure of 1.8kpa, and keep pressing for 30 minutes. Take out the stone, inject saturated steam again, control the temperature at 98°C, continue steaming for 3.5 hours, and collect the produced rehmannia glutinosa juice. Merge the rehmannia juice collected twice, heat and concentrate to 60kg. Dry the steamed Rehmannia glutinosa at 60°C for 10 hours at low temperature, add concentrated rehmannia juice, mix well, cover and suffocate for 12 hours, then dry at 65°C for 42 hours to obtain the finished rehmannia glutinosa.

Embodiment 3

[0032] Weigh 300kg of Rehmannia glutinosa, wash it with clean water, visually check that no sediment flows out, put it into a steamer, continuously feed saturated water vapor, and steam at a temperature of 100°C. Begin to collect the rehmannia glutinosa juice that produces after 1 hour, stop feeding steam in 3 hours. Cool down to 60°C, put a clean stone in the steamer, press the rehmannia glutinosa with a pressure of 1.6kpa, and keep pressing for 30 minutes. Take out the stones, inject saturated steam again, control the temperature at 100°C, continue steaming for 3 hours, and collect the resulting rehmannia juice. Merge the rehmannia juice collected twice, heat and concentrate to 60kg. Dry the steamed Rehmannia glutinosa at 60°C for 8 hours at low temperature, add the concentrated rehmannia juice, mix well, cover and simmer for 12 hours, and then dry at 70°C for 40 hours to obtain the finished rehmannia glutinosa.

Abstract

The invention discloses a process for processing prepared rehmannia root. The method includes: firstly steaming raw rehmannia root with saturated steam and collecting the generated rehmannia root juice, performing cooling to 50-65DEG C, extruding the rehmannia root, then introducing saturated steam to conducting steaming and collecting rehmannia root juice; and drying the well steamed prepared rehmannia root for 8-10h, then adding the rehmannia root juice to conduct stewing for 10-16h, and then further performing drying for 40-50h. The prepared rehmannia root processed by the method provided by the invention has a verbascoside content up to 0.040-0.057%, which is significantly higher than the requirement of 0.02% in 2010 edition ''Pharmacopoeia of the people's republic China'', and the processed prepared rehmannia root has stable quality and high qualified rate.

Description

technical field [0001] The invention relates to a processing technology of Chinese medicinal materials, in particular to a processing method of Rehmannia glutinosa. Background technique [0002] Rehmannia glutinosa is the fresh or dried root tuber of Rehmannia glutinosa of Scrophulariaceae, and it is one of the commonly used varieties of Chinese medicinal materials. Fresh Rehmannia glutinosa is slowly baked to 80% dry to obtain raw rehmannia glutinosa. The nature and flavor change from sweet, bitter, and cold to sweet and cold; After raw rehmannia is steamed into rehmannia glutinosa, its nature changes from cold to warm, its taste changes from bitter to sweet, and its efficacy changes from clear to tonic. Soreness and weakness of the waist and knees, bone steaming and hot flashes, night sweats and nocturnal emission, internal heat and thirst, blood deficiency and chlorosis, palpitations, irregular menstruation, metrorrhagia, dizziness and tinnitus, premature graying of the ...
