Problems solved by technology

Because the interface between the supernatant and the suspension layer is not clear, part of the suspension will be mixed into the supernatant, and the clarity of all the syrup cannot be fully guaranteed
With the increase of storage time, a small amount of suspended matter and sediment will gradually appear at the bottom of the bottle, which will affect the clarity

Embodiment 1

[0017] In order to improve the clarity of the antiviral syrup, the present embodiment adopts the method of filtering, including the following two processes:

[0018] Process 1: A microporous membrane cartridge filter element made of polypropylene (pore diameter of 0.45 μm) is used for pump pressure filtration.

[0019] Although this method can guarantee the quality of liquid medicine clarity, etc., there is a problem of poor operability, because the liquid medicine is viscous and easy to block the filter element, which will gradually cause the filtration rate to be too slow, and finally cause the pressure to rise and cause the pump to overload and shut down . It takes about 5 hours to filter a batch of 1000L liquid medicine. During this period, the filter element needs to be cleaned 1 to 3 times to ensure the operability of the filtration and increase the chance of contamination of the liquid medicine.

[0020] Process 2: Use 208 twill fleece for natural filtration.

[0021]...

Embodiment 2

[0023] In this embodiment, high-speed centrifugation is used to improve the clarity of the antiviral syrup, and the equipment used is a traditional Chinese medicine clarification tubular high-speed separator (GQLB150-Z, Liaoning Liaoyang Sunshine Pharmaceutical Machinery Co., Ltd.).

Abstract

The invention provides a method for preparing anti-virus syrup. The method provided by the invention comprises a step for separating a liquid medicament by adopting centrifuging operation, so that the clarity of the anti-virus syrup can be remarkably increased, and the quality level of a product is raised; the method has the characteristics of short process flow, low cost, small loss of active ingredients and complete recovery of the liquid medicament; and through high-speed running of a centrifuging machine, solid impurities such as suspended substances and the like are precipitated away rapidly under the action of the high centrifugal force acceleration, and mechanical impurities are removed physically, so that the product quality is not influenced.

Description

technical field [0001] The invention relates to a method for preparing antiviral syrup, in particular to a method for improving the clarity of antiviral syrup by adopting a centrifugal method. Background technique [0002] The antiviral syrup is made of nine raw materials of isatis root, forsythia, gypsum, anemarrhena, rehmannia, calamus, turmeric, patchouli and reed root. It has the effects of clearing away heat and dampness, cooling blood and detoxification, and is used for wind-heat Cold, febrile disease, fever and upper respiratory tract infection, influenza, mumps and other viral infection diseases. [0003] Antiviral syrup is a brown to tan liquid with a fragrant and sweet taste. In the current antiviral syrup preparation process, after the semi-finished syrup to be filled is frozen and left still (not less than 20 hours), the supernatant is separated and filled. The medicine solution containing sediment and suspended matter in the lower layer accounts for about 8-10...
