Description

[Detailed description of the invention] [Industrial application field] This invention is a two-step process such as coarse emulsification and fine emulsification, or rough dispersion and fine dispersion, in the emulsification and dispersion treatment of chemical products, foods, etc. This invention relates to a twin emulsifying and dispersing machine that is used when necessary. More specifically, the present invention relates to a technique of arranging two in-line emulsifying and dispersing machines, each of which performs a different process.

[Prior Art] An in-line emulsifying and dispersing machine has a rotor attached to a rotating shaft of a drive source, and a stator that faces the rotor and is fixed to a casing. Each has multiple rows of teeth arranged in a ring shape. Here, the teeth of the rotor and the teeth of the stator are opposed to each other, and the emulsification and dispersion process of the raw material liquid is performed in the space between them, that is, the shear gap. When a two-step emulsification and dispersion process is required, two such inline emulsification and dispersion machines are arranged in series and used as a two-stage emulsion and dispersion machine.

Conventionally, when in-line emulsifying and dispersing machines are arranged in series, the main method used is to connect the discharge port of one emulsifying and dispersing machine to the suction port of the other emulsifying and dispersing machine using piping such as various types of pipes. It was getting worse. Here, it is known that the piping needs to be as short as possible so that the second emulsifying and dispersing machine can immediately perform the processing after the first emulsifying and dispersing machine.

[Problem to be solved by the invention] However, depending on the site conditions where the emulsifying dispersion machine is installed and construction circumstances, a certain amount of piping length (for example, about 300 mm) is actually required. the result,
The liquid that has been emulsified and dispersed in the first machine is
Until it undergoes emulsification and dispersion treatment at the second stage,
For example, there is a delay time of around 10 seconds. and,
Due to the existence of such a lag time, for example, the liquid (semi-finished product) that has been emulsified and dispersed in the first machine
Crystallization, sedimentation, and separation of the components contained in the product occur, which may reduce the quality of the final product subjected to the two-step emulsification and dispersion treatment.

Furthermore, if the operation of the dual emulsifying and dispersing machine is stopped for a long time during the emulsifying and dispersing process, semi-finished products will remain in the piping, and their recovery and reprocessing will become a problem.

Furthermore, connecting two emulsifying and dispersing machines via piping occupies a relatively large space. Therefore, it is difficult to make it compact, and it is disadvantageous when it is combined with other equipment to form a unit.

This invention was proposed in view of the problems of the prior art described above, and when two in-line emulsifying and dispersing machines are arranged in series, processing by the first machine starts processing by the second machine. By minimizing the time required to process the product and minimizing the connection space between the two in-line emulsifying and dispersing machines, it is possible to reduce residual liquid and improve product yield, while also saving installation space. The purpose of the present invention is to provide a twin emulsifying and dispersing machine that can perform the following steps.

[Means for Solving the Problems] The dual emulsifying and dispersing machine of the present invention includes two in-line emulsifying and dispersing machines each having an emulsifying and dispersing member provided at the end of the output shaft. A discharge cover forming a discharge port of one emulsifying and dispersing machine and a suction cover forming a suction port of the other emulsifying and dispersing machine are integrally constituted as an adapter.

When implementing the present invention, the adapter is
Preferably, it is formed as a leg for installing a continuous emulsification/dispersion machine. This is because the two emulsifying and dispersing machines are balanced and vibrations are reduced, and at the same time, only the necessary emulsifying and dispersing machine needs to be disassembled for maintenance.

[Operation] According to the present invention having the above configuration, 2
Since the discharge port and suction port of the in-line emulsifying and dispersing machine are shared as an integrated adapter, the length of the member that connects the two emulsifying and dispersing machines is very short compared to the method of connecting with piping. Therefore, the installation space can be omitted. In addition, there is less residual liquid and the yield of the product is improved.

In addition, the second stage treatment can be carried out immediately after the first stage treatment, and the delay time between the first stage and the second stage is shortened, resulting in crystallization and sedimentation of the components contained in the semi-finished product. , separation becomes less likely to occur and improves the quality of the final product.

Furthermore, in connection with the fact that the installation space can be omitted, the entire device can be made compact.
Easy to combine with other equipment to form a unit.
