Description

[0002] Currently, the increasing demand for emulsions from a wide range of users and the growth of the market have brought tremendous opportunities to related manufacturing industries. However, issues such as production efficiency and quality control have constrained their development. In actual production, the stability of the emulsion determines the quality of the product. However, the stability of the emulsion is determined by factors such as the operating temperature of the production equipment, emulsification time, feeding sequence, mixing speed of the emulsifier, and stirring conditions. Among these, products prepared under different conditions will exhibit different stability and other physical properties, with the emulsification process being the key factor.

[0003] Emulsification processes are categorized into batch emulsification, semi-continuous emulsification, and continuous emulsification based on their preparation methods. However, all of these processes suffer from drawbacks such as complex preparation procedures, cumbersome feeding processes, small single-batch production volumes, and long-term product stability issues. Therefore, to meet market demands and product stability requirements, a parallel continuous rapid emulsion preparation device was designed. Utility Model Content

[0029] The working principle of this utility model is as follows:

[0030] Taking the preparation of a water-in-oil emulsion as an example, turn on the mold temperature controller 19, set the temperature, and heat the aqueous phase reactor 9 and the oil phase reactor 11 to provide a suitable temperature for dissolution; open the water inlet valve on the first pure water inlet branch pipe 5, and inject a certain amount of pure water into the aqueous phase reactor 9 through the water pump 2; add auxiliary materials into the aqueous phase reactor 9 through the auxiliary material pipe 95 on the aqueous phase reactor 9; then turn on the constant speed stirrer of the aqueous phase reactor 9 and stir for 15-30 minutes; continuously observe the stirring situation in the aqueous phase reactor 9 through the observation port on the aqueous phase reactor 9. The solution is dissolved completely. The oil inlet valve on the second glycerol branch pipe 12 is opened, and a measured amount of glycerol is injected into the oil phase reactor 11 via gear pump 24. Oil phase additives are added to the oil phase reactor 11 via auxiliary material pipe 115. The stirrer of the oil phase reactor 11 is turned on to stir and dissolve the solution. Simultaneously, the water inlet valve on the third pure water branch pipe 13 and the oil inlet valve on the second glycerol branch pipe 16 are opened, and pure water and glycerol are injected into the dilution vessel 18 according to a set ratio. The stirrer on the dilution vessel 18 is turned on to make the pure water and glycerol miscible. After the oil phase reactor 11 is completely dissolved, the solution in the completely dissolved aqueous phase reactor 9 is injected into the oil phase reactor 11 via the first feed pump 23 for stirring and emulsification, ultimately forming a water-in-oil emulsion. Finally, the water-in-oil emulsion in the oil phase reactor 11 is injected into the dilution vessel 18 via the second feed pump 22 for stirring and dilution, forming a uniform and stable water-in-oil emulsion.
