Problems solved by technology

[0003] In order to solve the problem of removing dissolved residues of existing silymarin, the present invention uses water-washed silymarin. Since silymarin is superfinely pulverized and suspended in water when stirred with water, the precipitation is slow, which prolongs the time for removing dissolved residues, resulting in low quality and low production efficiency of silymarin. Low problem, providing a method for washing silymarin to remove rapid precipitation and solidification in the process of dissolving residue

specific Embodiment approach 1

[0011] Embodiment one: the steps of the curing method of washing silymarin in this embodiment are as follows:

[0012] Step 1. Put 100kg of ultra-finely pulverized silymarin into the mixing tank according to the weight, then add 220kg of water into the mixing tank, open the mixing tank to stir the silymarin and water in the tank, and after stirring for 25-30 minutes, pour the mixture into the mixing tank Input steam into the tank, stop stirring when the water temperature in the tank reaches 53-57°C, and let it settle naturally. After 28-32 minutes, extract the precipitated dissolved residual water. Repeat the above process for 3 times. The more times, the better the effect of removing solvent residues (acetone Soluble in water, remove the solvent residue, that is, dissolve the acetone remaining in silymarin in water and discharge);

[0013] Step 2: Put the silymarin slurry removed from the dissolved residue in step 1 into the bucket, then add 45-55kg of pure water with a tempe...

specific Embodiment approach 2

[0015] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step 1, the water and silymarin are stirred and heated in the interlayer of the stirring tank. When the water temperature in the tank reaches 55°C, the stirring is stopped and natural precipitation is carried out. After 30 minutes, the The dissolved residual water precipitated in the stirring tank is drawn out; the silymarin slurry after removing the dissolved residual in step 2 is put into a storage tank, and then pure water at a temperature of 75°C is added into the tank, and the silymarin is solidified after 20 minutes. This implementation mode is the best implementation mode.

Abstract

The invention provides a method for quickly precipitating and solidifying washing silymarin in a process of removing a solvent residue, relates to a method for solidifying silymarin, and solves the problems that the production efficiency is low, the time of removing the solvent residue is prolonged, and the silymarin suspends in water when the silymarin is superfinely crushed and mixed with water, and precipitates slowly. The method comprises the steps of: I, stirring water and the silymarin, heating a stirring tank interlayer, stopping stirring when the water temperature in a tank reaches 53-57 DEG C, naturally precipitating, and pumping out solvent residue water separated from the stirring tank after 28-32 min; II, placing silymarin slurry, in which the solvent residue is removed, into a charging basket, adding purified water at the temperature of 70-80 DEG C into the basket, and solidifying the silymarin after 18-22min; and III, splitting the solidified silymarin into blocks, and placing into a dryer for drying. The method has the advantages that the silymarin precipitates and solidifies quickly by regulating water temperature, the time for removing the solvent residue is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a method for removing dissolved and solidified silymarin. In particular, it relates to a method for rapid precipitation and solidification during the process of washing silymarin to remove dissolved residues. Background technique [0002] At present, in order to improve the quality of the existing silymarin, the solvent residue (acetone) contained in the ultrafinely pulverized silymarin is removed, and the silymarin is washed with water. Since the silymarin is ultrafinely pulverized, it is suspended in water when it is stirred with water. The sedimentation time after washing with water is as long as more than 24 hours, which causes the problem of low production efficiency. Contents of the invention [0003] In order to solve the problem of removing dissolved residues of existing silymarin, the present invention uses water-washed silymarin. Since silymarin is superfinely pulverized and suspended in water when stirred with wat...
