Problems solved by technology

Shouhui laxative extract is dried by a vacuum dryer. During production, it was found that traditional steam heating has high drying temperature, and it is difficult to accurately control the size of the steam. The heating temperature fluctuates greatly, resulting in scorched gelatinization or hard lumps of the extract. , it is difficult to crush in the later stage; due to poor temperature controllability, it leads to high labor intensity, large energy consumption, and low heating efficiency; in addition, too high drying temperature will cause the decomposition of heat-sensitive components in the extract, resulting in a decrease in the content of active ingredients, resulting in Shouhui Tong Unstable quality of stool preparations

Embodiment 1

[0030] Example 1 Preparation of Shouhui Laxative Extract

[0031] 1) 5.0kg of ginseng, 12.0kg of Polygonum multiflorum, 14.0kg of cassia seed, and 16.0kg of aloe were refluxed with 10 times the amount of 40% ethanol for 1 hour, filtered and combined, and set aside;

[0032] 2) Add 7.5kg of medlar, 12.0kg of Citrus aurantii, and 5.0kg of Atractylodes macrocephala, add 5 times of water, soak for 0.5 hour, decoct for 1.0 hour, add 5 times of water, and decoct for 1.0 hour; combine the decoction, filter, reduce Concentrate under pressure until the relative density is 1.10 (80°C), add ethanol to make the alcohol content reach 40% (alcohol measurement), cool down for more than 12 hours, filter, and set aside;

[0033] 3) The above two filtrates were combined and concentrated under reduced pressure to a relative density of 1.30 (70°C).

Embodiment 2

[0034] Example 2 Preparation of Shouhui laxative extract

[0035] 1) 5.0kg of ginseng, 12.0kg of Polygonum multiflorum, 14.0kg of cassia seed, and 1.60kg of aloe were refluxed twice with 70% ethanol, adding 10 times the amount for the first time, and 8 times the amount for the second time, each time for 1.5 hours, and filtering the liquid merge, reserve;

[0036] 2) Add 7.5kg of medlar, 12.0kg of Citrus aurantii, and 5.0kg of Atractylodes macrocephala, add 8 times of water, soak for 2.0 hours, decoct for 2.0 hours, add 10 times of water, and decoct for 2.0 hours; combine the decoction, filter, reduce Concentrate under pressure to a relative density of 1.12 (80°C), add ethanol to make the alcohol content reach 70% (alcohol measurement), cool down for more than 36 hours, filter, and set aside;

[0037] 3) The above two filtrates were combined and concentrated under reduced pressure to a relative density of 1.36 (70°C).

Embodiment 3

[0038] Example 3 Preparation of Shouhui Laxative Extract

[0039] 1) 5.0kg of ginseng, 12.0kg of Polygonum multiflorum, 14.0kg of cassia seed, and 16.0kg of aloe were refluxed twice with 60% ethanol, adding 10 times the amount for the first time, and 8 times the amount for the second time, each time for 2 hours, and filtering the liquid merge, reserve;

[0040] 2) Add 0.75kg of medlar, 1.20kg of Citrus aurantii, and 0.50kg of Atractylodes macrocephala, add 10 times of water, soak for 1.0 hour, decoct for 1.5 hours, add 6 times of water, and decoct for 1.5 hours; combine the decoction, filter, reduce Concentrate under pressure to a relative density of 1.15 (80°C), add ethanol to make the alcohol content reach 60% (alcohol measurement), cool down for more than 48 hours, filter, and set aside;

[0041] 3) The above two filtrates were combined and concentrated under reduced pressure to a relative density of 1.33 (70°C).

Abstract

The invention relates to a drying method of traditional Chinese medicine extract, in particular to a vacuum drying method of Shouhui laxative extract. In the vacuum drying method, the circulating hot water with automatic temperature control is used as a medium to heat the Chinese medicine extract, thereby realizing the purpose of drying the Chinese medicine extract at low temperature. The method can overcome the disadvantages of traditional vacuum drying, such as the decomposition of heat-sensitive components of the extract due to high temperature, high energy consumption, low thermal efficiency, burnt or non-drying of the dry paste, and the like. The dry paste of traditional Chinese medicine obtained by using this drying method has high content of active ingredients and good quality of finished products; low moisture, which is convenient for preparation processing and storage of finished products; and maintains the clear fragrance of medicinal materials, natural color, loose and uniform texture, easy to crush; and can achieve Continuous and automatic production, with strong operability and practicability.

Description

technical field [0001] The invention relates to a drying method of traditional Chinese medicine extract, in particular to a vacuum drying method of Shouhui laxative extract, which belongs to the field of traditional Chinese medicine preparations. Background technique [0002] Traditional Chinese medicine believes that constipation is caused by conduction failure in the large intestine. It is manifested as constipation of stool, prolonged defecation cycle, dry and hard stool, or not hard stool, but the stool is not smooth or there is a feeling of incomplete defecation. Constipation, as a common clinical symptom, can accompany the onset of various acute and chronic diseases and bring great inconvenience to the work and life of patients. Especially in elderly patients, it can induce cardiovascular and cerebrovascular diseases and increase the risk of colorectal cancer. morbidity and can lead to depression or anxiety, seriously affecting people's quality of life. Conventional d...
