AI Technical Summary

Problems solved by technology

During the drying process, the essence of Clover is seriously lost or even destroyed, which reduces its medicinal effect, and its high water content is easy to mold and deteriorate, and it is not easy to store
[0004] Other existing clover drying methods, such as vacuum drying, usually have the disadvantages of high energy consumption, large loss of product activity, loose and fragile finished products, inconvenient transportation and storage, etc.

Embodiment 1

[0038] Clover drying method, the steps are:

[0039] A, slicing the clover raw material, the thickness is 2mm;

[0040] B. Spread the sliced ​​clover on a polytetrafluoroethylene film with a thickness of 90um, cool to -13°C~°C, the cooling rate is 33°C per hour, and then keep the temperature for 3 hours;

[0041] C. Vacuumize the system until the absolute pressure of the system is 75Pa, raise the temperature to 50°C, the heating rate is 1.9°C per hour, and maintain the absolute pressure and temperature for 30 hours;

[0042] D. Adjust the absolute pressure of the system to 25Pa, lower the temperature to 30°C, and the cooling rate is 20°C per hour, and maintain the absolute pressure and temperature for 2.5 hours. For specific parameter changes, please refer to figure 1 .

Embodiment 2

[0044] Clover drying method, the steps are:

[0045] A, slicing the clover raw material, the thickness is 3mm;

[0046] B. Spread the sliced ​​clover on a polytetrafluoroethylene film with a thickness of 100um, cool to -14°C, the cooling rate is 34°C per hour, and then keep the temperature for 2.9 hours;

[0047] C. Vacuumize the system until the absolute pressure of the system is 80Pa, raise the temperature to 49°C, the heating rate is 2.1°C per hour, and maintain the absolute pressure and temperature for 29 hours;

[0048] D. Adjust the absolute pressure of the system to 30Pa, lower the temperature to 25°C, and the cooling rate is 24°C per hour, and maintain the absolute pressure and temperature for 2 hours. For specific parameter changes, please refer to figure 2 .

Embodiment 3

[0050] Clover drying method, the steps are:

[0051] A, slicing the clover raw material, the thickness is 4mm;

[0052] B. Spread the sliced ​​clover on a polytetrafluoroethylene film with a thickness of 100um, cool down to -16°C, the cooling rate is 36°C per hour, and then keep the temperature for 2.7 hours;

[0053] C. Vacuumize the system until the absolute pressure of the system is 85Pa, raise the temperature to 48°C, the heating rate is 2.1°C per hour, and maintain the absolute pressure and temperature for 28 hours;

[0054] D. Adjust the absolute pressure of the system to 35Pa, lower the temperature to 20°C, and the cooling rate is 28°C per hour, and maintain the absolute pressure and temperature for 1.5 hours. For specific parameter changes, please refer to image 3 .

Abstract

The invention relates to a radix tetrastigme drying method which comprises the steps of radix tetrastigme raw material slicing, thin film laying for freezing, drying at the first stage and drying at the second stage. According to the radix tetrastigme drying method, by reasonable setting of parameters such as the time of thin film laying for freezing and the drying durations at the first and second stages as well as the temperature and the pressure, the activity of radix tetrastigme can be retained more completely after the radix tetrastigme is dried; effective components of the radix tetrastigme dried by the method disclosed by the invention can be retained to the maximum extent; furthermore, a finished product is high in breakage resistance performance; the dried radix tetrastigme finished product can be prepared into electuary, an oral preparation and the like.

Description

technical field [0001] The invention relates to a method for drying Clover. Background technique [0002] Clover, correct name: Cliff climbing vine, also known as golden thread hanging gourd, snake monkshood, stone mouse, belongs to the order Rhamna, herbaceous vines of the grape family. The whole plant can be used as medicine, and the medicinal effect of underground tubers and fruits is the best. The medicinal part of the Chinese medicinal material Cloverleaf is the root, fruit or whole plant of Cliffaceae Cliffaceae, which can be harvested throughout the year, and can be dried or used fresh. It is mild in nature and slightly bitter in taste, and has the effects of clearing heat and detoxifying, dispelling wind and reducing phlegm, promoting blood circulation and relieving pain, etc. [0003] The traditional clover drying processing method is to dry the slices and then fumigate them and pack them. During the drying process, the essence of Clover is seriously lost or even...
