Emulsifying cavity device for high-pressure homogenizing emulsification equipment and method for emulsifying cavity device

Abstract

The invention relates to the technical field of high-pressure homogenizing emulsification equipment, in particular to an emulsifying cavity device for the high-pressure homogenizing emulsification equipment and a method for the emulsifying cavity device. The emulsifying cavity device comprises a hydraulic plunger pump, a feed cup, a check valve, a pressure gauge, a heat exchanger and a discharge hole, and is characterized in that the hydraulic plunger pump is connected with a main pipeline of the equipment; one end of a tap of the main pipeline is connected with a funnel discharging hole of the funnel-shaped feed cup by the check valve, and the other end of the main pipeline is connected with a feeding hole of a Y-shaped spray cavity structure; the pressure gauge is arranged at one end of the tap of the main pipeline between the Y-shaped spray cavity structure and the check valve; a discharge hole of the Y-shaped spray cavity structure is connected with a feed opening of the heat exchanger by a pipeline; a discharge hole is formed at the other end of the heat exchanger; and a water inlet and a water outlet for a heat supply exchange medium are formed on the heat exchanger. The emulsifying cavity device is novel in structure, and two liquid flows of materials collide with each other at an intersection by utilizing the specific Y-shaped spray cavity structure, so that the grain diameters of the materials are reduced, and the materials are mixed uniformly and stably.

Description

[technical field] [0001] The invention relates to the technical field of high-pressure homogeneous emulsification equipment, specifically an emulsification chamber device and method for high-pressure homogeneous emulsification equipment prepared by nanotechnology, mainly used for nano-liposomes, fat emulsions, suspensions, Nano-dispersion preparation of chemical materials, etc. [Background technique] [0002] The process of uniformly dispersing a liquid in another immiscible liquid with tiny droplets is called emulsification, which is a liquid-liquid interface phenomenon. [0003] In industrial production, the mechanical equipment to realize the above emulsification process is mainly an emulsifier. At present, there are three main types of emulsification machines: emulsification mixer, colloid mill and homogenizer. Different types of emulsification machines have different structures and performances. The size of the emulsion particles (dispersibility) and the quality of the...

Problems solved by technology

[0004] Generally, the agitating emulsifier widely used in cosmetics factories has poor dispersion, large and rough particles, poor stability, and easy pollution. However, it is easy to manufacture and cheap. Just pay attention to the selection The reasonable structure of the machine and the proper use can also produce popular cosmetics with general composite quality requirements; colloid mills and homogenizers are relatively good emulsification equipment, but in recent years, with the advent of the nanotechnology era, traditional emulsification Machines have been unable to achieve nanoscale dispersion standards

[0005] For example, the traditional valve structure is a homogeneous valve, which is composed of a valve seat, a valve core, and a retaining ring. Emulsification, although the structural design is simple, but the accuracy is not high, so the pressure is relatively low, and the highest can reach 1500bar abroad. Due to the problem of machining accuracy in China, the current maximum working pressure is generally low, generally at 1000bar, so most of them are used Also only limited to milk, food emulsification
