TH7660EX - Processors and methods for making microcapsules - Google Patents

Abstract

This invention is a continuous process or a group and a machine. Completed for the production of filled microcapsules containing liquid, gas, solid or multi-phase materials. The microcapsules are formed by applying high pressure for a short time to a mixture of the filling and shell material. And by reducing the pressure accordingly, for example, by passing the capsule through a chamber with a transverse plate, the fabrication also included a method for adjusting the size of the microcapsules and the thickness of their shells. The microcapsules can be made with a multi-layer shell. To increase its strength Or is it a multi-purpose capsule with two or more fillings? The prefabricated unit consists of a device for collecting the filling material mixture and the residual (33), compression chamber (34), pressure reducing chamber (36), alternate cycle (37), the pressure reducing chamber may include pipes (59) with Transverse plates (60) to increase turbulence.The invention was primarily useful in producing time-dispersed capsules and producing micro-capsules at the desired fraction of the time by conventional methods.

Claims (4)

1. A method of capsule making that consists of a process of mixing the filling material and A shell material that applies pressure to the mixture The pressure applied is sufficiently large enough to cause the capsule to rise and at the tip to drop, respectively. 2. Method according to Clause 1, where the procedure of Reducing the total pressure phase of induction of agitation in the mixture. 3. Method according to claim 2, where the induction The turbulence is composed of a minimum of the mixture through a chamber with a transverse plate. 4.Method according to claim 1, where the pressure is exerted on a period of magnitude 1.
