Example Embodiment

[0031] Example 1:

[0032] 1) The planed antler sheet with a thickness of 0.1~0.2mm is flattened with an absorbent sheet and then laid flat in a box at 30°C with a thickness of 2~4cm;

[0033] 2) Then use a heat pump cooler to cool the air at the junction of the box and the outside, so that the air temperature in the junction space is reduced to 10 ℃, reaching the dew point temperature, and combined with the ram centrifuge to condense the air in the junction space The moisture is discharged to keep the air temperature in the box at 10℃ and the relative humidity at 30%, that is, the air with relatively high humidity is discharged, and the air with relatively low humidity is kept in the box to continue recycling;

[0034] 3) Use a heat pump heater to heat the air with a relative humidity of 30% to 30°C;

[0035] 4) Finally, the fan is used to spray the heated air from the nozzle into the box, forming a laminar flow with a wind speed of 7-9m / s, forming a partial negative pressure of 50 P...

Example Embodiment

[0041] Example 2:

[0042] 1) Lay the cut bergamot slices flat in a box at 45°C with a thickness of 4-6cm;

[0043] 2) Then use a heat pump cooler to cool the air at the junction of the box and the outside, so that the air temperature in the junction space is reduced to 20 ℃, reaching the dew point temperature, and combined with the ram centrifuge to condense the air in the junction space The moisture is drained to keep the air temperature in the box at 20℃ and the relative humidity at 20%.

[0044] 3) Use a heat pump heater to heat the air with a relative humidity of 20% to 45°C;

[0045] 4) Finally, a fan is used to inject the heated air from the nozzle to form a laminar flow with a wind speed of 7-9m / s and a partial negative pressure of 40 Pa. The bergamot slices are dried for 12-14h under this condition. can.

Example Embodiment

[0046] Example 3:

[0047] 1) Spread the cut tangerine peels in a box at 40°C, with a thickness of 5-10cm;

[0048] 2) Then use a heat pump cooler to cool the air at the junction of the box and the outside, so that the air temperature in the junction space is reduced to 15 ℃ to reach the dew point temperature, and combined with the ram centrifuge to condense the air in the junction space The moisture is discharged to keep the air temperature in the box at 15℃ and the relative humidity at 40%.

[0049] 3) Use a heat pump heater to heat the air with a relative humidity of 40% to 40°C;

[0050] 4) Finally, a fan is used to spray the heated air from the nozzle to form a laminar flow with a wind speed of 7-9m / s, forming a local negative pressure of 70 Pa. The dried tangerine peel can be dried for 4-6h under this condition. .

Abstract

The invention discloses a normal-temperature dry processing technology of traditional Chinese medicine decoction pieces. By virtue of the technology, the traditional Chinese medicine decoction pieces can be quickly dried under the condition with the temperature close to the normal temperature by controlling the air relative humidity, air pressure and temperature of a drying oven during drying with the adoption of a technology of punching and centrifuging air and then drying. The drying time is as short as 4 hours; medicinal components of the traditional Chinese medicine decoction pieces are well retained and the edible and medicinal effects are improved; by virtue of the dry processing technology, the finished products of the traditional Chinese medicine decoction pieces are relatively bright in appearance, character, color and luster; extractums are increased; the effect of the traditional Chinese medicine decoction pieces is improved.

Description

technical field [0001] The invention relates to a drying processing technology for decoction pieces of traditional Chinese medicine. Background technique [0002] Drying processing of Chinese herbal medicine is a key process in the process of Chinese medicine processing. [0003] The drying method of traditional Chinese medicine pieces is to dry the pieces of Chinese medicine by drying, drying in the sun, drying in the shade or drying at low temperature. Ten days to one month, the production cycle is long; there is no specific quantitative index for the temperature of the low-temperature drying method, which may easily cause the content of Chinese herbal pieces to be unstable, and the use effect of Chinese herbal pieces cannot be guaranteed. [0004] In order to reduce the difficulty of drying TCM decoction pieces, improve work efficiency, reduce energy consumption, and increase the dissolution of active ingredients in TCM decoction pieces, it is urgent to improve the dryin...
