Microcapsule preparation device

Abstract

The invention belongs to the technical field of microcapsule manufacturing equipment, and particularly discloses a microcapsule preparation device which comprises a dripping system, a conveying and forming system and a collecting system, and the conveying and forming system comprises a wire groove and a liquid storage barrel; the dripping system comprises a conveying pump and a dripping disc, theconveying pump is used for conveying materials to the dripping disc, a cavity is formed in the dripping disc, and a distribution plate is arranged in the cavity; an air inlet base is arranged on the dripping tray, the lower end of the air inlet base is communicated with the air cavity, an air outlet base is arranged on the dripping tray, an air hole communicated with the air cavity and the outsideof the air cavity is formed in the air outlet base a through needle is arranged on the lower side of the distribution plate, and a guide wall for guiding air below the through needle is arranged on the lower side in the air hole and located over the wire groove; the collecting system comprises a material box used for collecting microcapsules, and the material box is located below the water outletend of the wire groove. The preparation process is easy to control, the repeatability is good, microcapsules with small difference can be prepared in batches, and good support is provided for industrial production.

Description

technical field [0001] The invention belongs to the technical field of microcapsule manufacturing equipment, and in particular relates to a microcapsule preparation device. Background technique [0002] Microcapsule technology is a technology that uses film-forming materials to coat solid liquid or gas into inclusions with a functional core-shell structure. Microcapsule technology has been extended to different fields including medicine, agrochemicals, spices, coatings, food science, and preparation of cosmetics. After microencapsulation, some substances can be stored in the form of core materials in a fine state and released when needed, and their color, shape, heat resistance, solubility, volume, quality, etc. will change. Microencapsulation technology mainly has the following advantages: ① Microencapsulation can change the shape of the material, thereby changing the state, quality and volume of the material; ② Microencapsulation can control the release of the core materi...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing microcapsule products are spherical, and the shape is relatively single, which cannot meet the needs of the market. In order to solve the above problems, the Chinese invention patent with the notification number CN105727854B discloses a wire groove type production device for sheet microcapsules. Gel dropper, saline solution and wire groove are used to prepare sheet-shaped capsules. Although this device can produce microcapsules different from spherical ones, the gel solution is only dripped through the gel dropper, which is difficult Controlling the size and speed of the droplets leads to large differences in the final formed microcapsules, and the quality is difficult to guarantee
