Problems solved by technology

[0005] However, different forms of medicinal materials have different degrees of absorption of microwave energy, resulting in incomplete sterilization, and because the water content of sterilized materials is only about 7% to 13%, the sterilization effect of ordinary microwave sterilization is poor and difficult to control.
[0006] Existing drying and sterilization devices and sterilization methods commonly used in the production process of traditional Chinese medicine have disadvantages or imperfections in varying degrees. Not good, loss of active ingredients, not suitable for drying and sterilization of large quantities of materials, etc., resulting in poor quality stability and uniformity of Chinese herbal pieces

Embodiment example 2

[0067] Implementation case 2: root and rhizome decoction pieces, taking Chuanxiong as an example

[0068] According to the production batch, take 100kg of Chuanxiong decoction pieces (the microbial limit test results show that the bacteria and mold contents are 50000cfu / g and 10000cfu / g respectively), open the conveyor belt through the control system, and send the materials in the hopper into the microwave drying chamber; set The power density of microwave is 0.1-0.15w / g, the final temperature of microwave drying is 60-65℃, the drying time is 45-50min, and then the drying starts.

[0069] When the drying is over, the conveyor belt will input a certain amount of material into the detection chamber for near-infrared spectrum collection and analysis of the moisture content of the material. The spectral scanning range is 4000-12500cm -1 , the number of scans is 32, and the resolution is 8cm -1 , use the built-in background of the detection chamber as a reference to collect spectr...

Embodiment example 3

[0071] Implementation case 3: flower decoction pieces, taking honeysuckle as an example

[0072] According to the production batch, take 100kg of honeysuckle as the material (the microbial limit test results show that the bacteria and mold contents are 15000cfu / g and 20000cfu / g respectively), open the conveyor belt through the control system, and send the material in the hopper into the microwave drying chamber; set the microwave The power density is 0.08-0.10w / g, the final temperature of microwave drying is 50-55°C, the drying time is 30-35min, and then the drying starts.

[0073] When the drying is over, the conveyor belt will input a certain amount of material into the detection chamber for near-infrared spectrum collection and analysis of the moisture content of the material. The spectral scanning range is 4000-12500cm -1 , the number of scans is 32, and the resolution is 8cm -1 , use the built-in background of the detection chamber as a reference to collect spectra; if t...

Abstract

The invention relates to a traditional Chinese medicine decoction piece drying and sterilizing integrated device and method. The device comprises a drying device, a sterilizing device and a detecting device. The drying device comprises a microwave generator; the sterilizing device comprises a radio frequency generator and a hot air device; Low-frequency microwaves are selected for drying treatment, so that the advantages of high penetrability, easiness in power regulation, good drying uniformity and the like are achieved, energy conservation and emission reduction can be better realized, and the drying time is shortened; the loss of effective components in the drying process of the traditional Chinese medicine decoction pieces can be reduced; and a radio frequency-hot air combined sterilization mode is selected, so that the applicability is wide, the stability is good, and large-batch materials are easy to treat.

Description

technical field [0001] The application belongs to the field of processing of decoction pieces of traditional Chinese medicine, and in particular relates to an integrated device and method for drying and sterilizing decoction pieces of traditional Chinese medicine. Background technique [0002] The production process of Chinese herbal pieces generally includes a series of processes such as cleaning, softening, cutting, drying, processing, and ingredients of Chinese herbal medicines. Moisture is one of the most basic elements to control the quality of Chinese herbal medicines. Generally, the water content of Chinese herbal medicines should be controlled at 7 % to 13%, decoction pieces with too high water content are prone to insects and mold during storage, which will cause the active ingredients of the drug to decompose and deteriorate, affecting the therapeutic effect; There are many kinds of decoction pieces with different properties, and the water content requirements of d...
