Embodiment 1
[0031] This embodiment provides an on-line detection device for ash content prepared from Chinese herbal pieces, such as figure 1 As shown, it includes a conveyor belt 1, a ray transmitter 3 and a ray receiver 4 (the ray is preferably microwave, X-ray or gamma ray) for transmitting samples of decoction pieces of Chinese herbal medicine to be tested, the ray transmitter 3 and the ray receiver 4 Distributed on both sides of the conveyor belt 1 (in this embodiment, the ray emitter 3 is located above the conveyor belt 1, and the ray receiver 4 is located below the conveyor belt 1), the ray exit of the ray emitter 3 faces the ray receiver 4, and the ray emits The device 3 is used for emitting rays to the sample of Chinese herbal decoction pieces, and the ray receiver 4 is used for receiving the ray signal passing through the sample of Chinese herbal decoction pieces. The ash content detection model corresponding to the Chinese herbal decoction piece sample is stored, and is used to...
Embodiment 2
[0037]This embodiment provides an on-line detection method for ash content in prepared Chinese herbal medicine slices, which is carried out by using the online ash content detection equipment in Example 1, and the steps are as follows:
[0038] (1) Take the cleaned rehmannia glutinosa of the same batch to be detected, and detect its cellulose content f (wt%) and ash content Ash (wt%):
[0039] The detection method of cellulose content f (wt%):
[0040] Dry the cleaned Rehmannia glutinosa to constant weight, powder it through an 80-mesh sieve, weigh 2 grams, and dry it in an oven at 60°C to constant weight W 1 ;Add 150mL of 2mol / L hydrochloric acid, put it into an autoclave, and keep it at 105°C for 30 minutes; take it out, filter it with a sand core funnel, wash it with deionized water until neutral, then wash it twice with ethanol and acetone Put the filter residue in a 150mL beaker, add 15mL of 75% sulfuric acid, acid hydrolyze at room temperature for 5 hours, add 100mL of ...
