Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pharmaceutical engineering and chemical machinery, and particularly relates to a double-spiral mixing and stirring device for cream. BACKGROUND

[0002] Cream is a kind of drug dosage form, which is a semi-solid external preparation made by uniformly mixing drugs with suitable bases. It has the characteristics of both emulsion and ointment, and is delicate and easy to apply, and can be evenly distributed on the skin surface. The base in the cream not only has a shaping effect, but also can affect drug release and absorption. It is widely used, and can be used for the treatment of skin diseases, such as anti-inflammatory, antibacterial, and antipruritic, and can also be used for skin care, such as moisturizing and nourishing.

[0003] The mixing and stirring device used in the production of existing cream mixes the cream production raw materials in the device by setting stirring blades during use, but the existing mixing and stirring device can only mix the raw materials in a single direction. Since the cream production raw materials usually contain multiple components, such as oil phase, water phase, and active ingredients, the physical properties (such as density, viscosity, and solubility) of different components are different. Mixing in a single direction can not fully contact and disperse the components, resulting in uneven mixing, and it takes a longer time to make the components reach a uniformly mixed state. This not only increases the production cycle and reduces the production efficiency, but also may cause the raw materials to deteriorate or degrade during a long stirring process. To solve the above problems, it is necessary to design a double-spiral mixing and stirring device for cream. SUMMARY

[0035] In the first stirring mechanism, the servo motor drives the vertical screw to rotate, and the material is pushed in the vertical direction by the spiral structure, and the blades at the upper end of the vertical screw further promote the mixing of the material in the vertical direction, and the end of the blade can remove the material attached to the inner wall of the container, reduce the material residue, and improve the material utilization rate.

[0036] When the second stirring mechanism works, the driving mechanism drives multiple horizontal shafts to rotate, the horizontal screw on the horizontal shaft stirs the material in the horizontal direction, and the cutting blade at the end of the horizontal shaft cuts and stirs the material during rotation, which helps to break the agglomeration of the material and promote the uniform mixing of the material in the horizontal direction.

[0037] Through the cooperation of the above structure and working principle, the emulsion double-spiral mixing and stirring equipment effectively solves the problem of uneven mixing caused by single-direction stirring of traditional equipment, improves the production efficiency and product quality. Through uniform dispersion of the material in the vertical and horizontal directions, the quality of the mixed emulsion is more stable. Since multiple-direction full mixing can be realized, compared with the traditional single-direction stirring equipment, the device can make each component reach the state of uniform mixing faster, greatly shorten the production cycle, improve the production efficiency, and meet the demand of large-scale production. Multi-directional stirring enables the material to be fully mixed in a short time, avoiding the problem of long-time stirring caused by uneven mixing of traditional equipment due to single-direction stirring.
