Embodiment 1
[0017] Preparation of Yikunning Tablets
[0018] Weigh 90g of angelica, 60g of Cyperus cyperi, 15g of cassia bark, 60g of Rehmannia glutinosa, 60g of white peony, 60g of Chuanxiong, 60g of Motherwort, 30g of Corydalis Corydalis, 15g of trigonum, and 15g of orange peel.
[0019] The above ten flavors are crushed into coarse powder, according to the percolation method under the item of liquid extract and extract, use 45% ethanol solvent, after immersion for 48 hours, slowly percolate at a speed of 1-3ml per minute, and collect the primary percolation The liquid is about 750ml, and the percolation is continued until the filtrate is nearly colorless, the first eluate is combined, and the filtrate is concentrated to a relative density of 1.06-1.12 (at 50° C.) to obtain a concentrated solution.
[0020] Add 80g of dextrin, filter, and spray dry. The air inlet temperature during spray drying is 170-180°C (preferably 180°C), the outlet air temperature is 70-80°C (preferably 80°C), and...
Embodiment 2
[0022] Preparation of Yikunning Capsules
[0023] The preparation process is the same as in Example 1, except that the granules are filled into capsules to obtain 400 capsules.
Embodiment 3
[0025] Preparation of Yikunning Granules
[0026] The preparation process is the same as in Example 1, except that the added forming agent is 120 g of lacto-oligosaccharide, dry granulated (material temperature below 60° C.), and granulated to obtain 200 g of brown-yellow granules with slight gas and sweet taste. Fill into bags, 1g per bag, to get 200 bags of granules.
[0027] During the specific preparation process:
[0028] Influence of Relative Density of Concentrate on Spray Drying Process
[0029] The spray drying efficiency of the liquid medicine is related to the concentration of the liquid medicine. According to Table 1, the relative density of the concentrated liquid is 1.06-1.12 (50°C) as the concentration end point.
[0030] Table 1 Effect of relative density of concentrate on spray drying process
[0031] Effect of relative density of concentrate on spray drying process
[0032] <1.06 The spray drying particles are too fine, the yield is low, a...
