DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0037] Embodiment 1: Referring to the accompanying drawings in the specification, Figure 1 As shown in the figure, a preparation process of licorice granules comprises the following steps:

[0039] S1.2, put the soaked licorice into a frying pan, add water, slowly fry with a small fire, control the frying pan at 170℃, until the licorice turns into dark yellow and is not sticky, after frying is completed, take out the licorice and cool it, then licorice can be obtained;

[0040] S1.3, put the other half of the raw licorice and the fried licorice into the tank, decoct 3 times, decocting temperature is 100℃, decocting time is 2h each time, and the extracted liquid after decoction is flowed into the sedimentation tank to stand overnight;

[0041] S1.4, heat and concentrate the extracted liquid after step S1.3 by the concentrator, and put the concentrated material into the spray dryer 1 to atomize and dry to form licorice extract, and then put the licorice extract, sucrose and dextrin in the order of weight ratio 3:1:1 into the high-speed mixer to stir and mix, then pass the mixed material through the granulator to obtain licorice granules and package.

[0042] Specifically, before processing, the weight of licorice is confirmed by an electronic scale, and the information such as the name and quantity of the medicinal material is checked to be consistent with the production prescription. In the roasting process, the weight ratio of water added to licorice is between 1:(10-12). In the process of decocting for three times, the weight ratio of the total weight of the other half of raw licorice and roasted licorice to water is 1:8, 1:6 and 1:6, respectively.

[0043] The specific working principle of the concentrator is as follows:

[0044] Open the condenser cooling water valve to open the concentrator vacuum, open the feed valve, and suck the supernatant of the extraction liquid in the sedimentation tank to the just-out concentrator sight glass position. Stop feeding, open the heater steam valve, adjust the steam valve opening after the liquid boils, maintain the vacuum degree in the required range, and stabilize the concentration. Open the feed valve continuously to maintain the liquid level in the middle of the concentrator sight glass. After the extraction liquid is completely fed, continue to concentrate until the moisture content of the concentrated liquid is less than or equal to 60%, stop concentrating, close the steam valve, close the vacuum valve and empty it, and pump the concentrated material into the concentrate storage tank of the spray dryer.

[0045] After drying and forming, the granulator can select a rotary granulator or add the high-speed mixed material to the rotary granulator for multiple times to form granules, which are discharged into a clean container, and finally can be optionally dried again by a dryer.

[0046] The fluidized bed dryer is used, the induced draft fan is opened, the air heater steam valve is opened, the inlet air temperature is set to 100°C, the outlet air temperature is set to 60°C (the target is to control the material temperature to 60±5°C), the granular material from the rotary granulation process is started to dry, the moisture content of the material is controlled to be not more than 5% (detected by a field rapid moisture meter), and after the moisture content meets the standard, the material is discharged into a clean stainless steel barrel, sealed with a cover, labeled, and the QA is notified to take samples. The semi-finished product is detected according to the semi-finished product inspection standard of the liver and gall granules, and after the detection is qualified, a semi-finished product detection qualified report is issued to the workshop, so that the next process can be entered for packaging.

[0047] Finally, the licorice granules are effectively sealed and packaged in the form of inner and outer packaging. The licorice granules in the stainless steel barrel are taken from the material storage room and put into a clean granule packaging machine. The weight of each bag is 500g according to the packaging instruction, the packaging weight of the granule packaging machine is set to 502g / bag, the information printed on the packaging bag is checked, and after the check is correct, the product is packaged. The bag is put into a sealing machine to seal the bag, the temperature is between 205-210°C, attention is paid to prevent the aluminum plastic bag from being misaligned and wrinkled, and the seal is tight. The packaged licorice granules are transferred to the outer packaging room through the transfer window.
