Liquid microcapsule curing device and method based on infrared heating

Abstract

The invention discloses a liquid microcapsule curing device and method based on infrared heating. The device comprises a coaxial flow dropper (1), a curing cavity (2) and an iron support (8). The iron stand (8) is connected with a dropper clamp (83) used for clamping the coaxial flow dropper (1) and a curing cavity supporting clamp (82) used for clamping the curing cavity (2). The coaxial flow dropper (1) extends into the curing cavity (2) from the top of the curing cavity (2); a discharging pipeline (3) is arranged at the bottom of the curing cavity (2); a discharge valve (6) is arranged on the discharge pipeline (3), and a discharge port (7) is formed in the tail end of the discharge pipeline (3); the upper part of the curing cavity (2) is an inverted conical cavity with a hyperbolic cross section, and an exhaust port (23) is formed in the top of the curing cavity (2); the lower portion of the curing cavity (2) is a spherical cavity, a plurality of infrared heating modules (21) are evenly arranged on the inner surface of the cavity, and each infrared heating module is composed of an infrared metal heating belt, a PET insulating layer and a temperature control element.

Description

technical field [0001] The invention relates to a liquid microcapsule curing device and method based on infrared heating, and belongs to the technical field of microparticle preparation. Background technique [0002] Microcapsule technology is a technology that wraps trace substances in polymer films, and is a micro-packaging technology for storing solids, liquids, and gases. Specifically, microcapsule technology refers to completely covering a target object (core material or inner phase) with various natural or synthetic polymer compound continuous films (wall material or outer phase), and The original chemical properties are not damaged at all, and then the function of the target object is displayed again through some external stimulation or slow release, or the core material is protected by the shielding effect of the shell wall material of the microcapsule. [0003] The solidification of the shell of the liquid microcapsule can protect the wrapped material and isolate i...

Problems solved by technology

[0004] However, there are three problems in the existing solidification method of liquid microcapsules: first, the contents of microcapsules are mostly solid particles, and there is a lack of microcapsule preparation and solidification devices whose contents are liquid; secondly, the material of the liquid microcapsule shell Using gelatin and cold curing method, the curing efficiency is low; third, the shape of the liquid microcapsules cannot be controlled, and it is easily affected by external disturbances in the preparation process and presents an irregular shape, which seriously affects the curing process and the performance of the microcapsules

However, in the method of this patent, the core material and the wall material need to be uniformly mixed first, and the process is cumbersome; after the microcapsules are formed, they will be attached to the drying medium, and the subsequent collection process is difficult; Unified, the quality of microcapsules is difficult to be guaranteed
