Technical Field
[0001] The utility model relates to the technical field of mixing antibacterial creams and ointments, in particular to mixing equipment for producing and processing antibacterial creams and ointments. Background Art
[0002] Antibacterial ointment is a commonly used topical medicine, mainly used to prevent and treat various infectious diseases. The ointment production process includes multiple steps, such as raw material preparation, raw material mixing and stirring, emulsification, etc. Among them, the raw material mixing and stirring process requires the use of mixing equipment, which is mainly used to fully mix various raw materials to ensure the texture and efficacy of the ointment.
[0003] The main raw materials of antibacterial creams usually include antibacterial ingredients, matrix, stabilizer, thickener, etc., and various drug ingredients with antibacterial effects. These ingredients can be Chinese herbal medicines or Western medicine ingredients. For example, some antibacterial creams may contain ingredients such as Cnidium monnieri, Stemona tuberosa, Dictamni, Trillium gracile, Coptis chinensis, chlorhexidine acetate, etc., and some antibacterial creams may also contain clobetasol propionate.
[0004] The mixing equipment needs to mix the raw materials in a certain proportion and stir them to make them fully mixed. This step requires careful control of temperature and time to ensure that the raw materials can be fully dissolved and mixed.
[0005] The mixing temperature of the raw materials of antibacterial cream usually depends on the specific ingredients and the required physical state. In some documents, such as "Study on Optimization of Preparation Process of Fule Cream", it is mentioned that the cream matrix is water-in-oil type, and the optimal molding process parameters are two-phase mixing temperature of 65°C1. In another document "A method for preparing an antibacterial and deodorizing wormwood toothpaste and natural plant antibacterial extracts used therein", the mixing temperature is set to 50-70°C. Therefore, the optimal temperature for mixing antibacterial creams of different formulas may not be consistent, and the mixing temperature needs to be controlled.
[0006] The antibacterial cream is thick and semi-fluid and has a certain degree of adhesion, so after mixing, part of the cream will adhere to the inside of the mixing equipment, which will not only cause waste of raw materials, but also affect the normal operation of the mixing equipment.
[0007] Traditional mixing equipment is only equipped with a mixing and stirring structure, and most of them are not equipped with a temperature monitoring or adjustment structure, and no auxiliary scraping structure is set to address the problem of ointment adhering to the inner wall of the equipment. Since the antibacterial ointment raw materials generally contain solid raw materials of Chinese medicinal ingredients and other liquid raw materials, they cannot be mixed and stirred at the same time. There is no quantitative measurement of liquid capacity or solid weight when feeding, so the raw materials need to be weighed separately, and there is no structure for pre-crushing the Chinese medicinal raw materials.
