Process for preparing hard hollow capsules from material having thermal gel performance

Abstract

The invention is applicable to the technical field of production of hard hollow capsules, and discloses a process for preparing the hard hollow capsules from a material having a thermal gel performance. The process comprises the following steps: preparing a liquid at normal temperature, heating a mold body, dipping glue and forming, drying and cooling, and de-molding and brushing oil. The process for preparing the hard hollow capsules from the material having the thermal gel performance disclosed by the invention breaks through a conventional hollow capsule production process; on the basis of the principle that gel is generated by thermal gel when encountering water, exiting cold-mold hot-liquid production is replaced by cold-liquid hot-mold production, so that a preparing mode of a preparation liquid is changed, the production process is simplified, energy consumption is reduced, production cost is reduced and a material utilization rate is improved by 30-40%; and the addition of any coagulant aids is avoided, so that a risk that a mutual cross-linking reaction occurs between materials is eliminated and the safety grade of a finished product is improved. The preparation process shortens a drying time, facilitates production and management, improves a production efficiency, effectively controls the stability and the uniformity of the finished product and significantly improves the current situation that the finished product is high in weight difference.

Description

【Technical field】 [0001] The invention relates to the technical field of production of hard hollow capsules, in particular to a manufacturing process of hard hollow capsules using materials with thermogel properties. 【Background technique】 [0002] The traditional hard hollow capsule manufacturing process has been passed down for more than 100 years. The main feature of his manufacturing process is to use the principle of gelatin's own freezing force to shape. In order to ensure the stability of the molding, the ambient temperature is also required to be low. Simply put, the gelatin preparation liquid is hot, the mold is cold, and the low temperature environment is used to complete the process and meet the product requirements. Even the newly developed non-animal source hard hollow capsule manufacturing materials in recent years have not broken through this traditional model in the manufacturing process. Seaweed polysaccharide materials have properties similar to animal-de...
