Production system for hollow alginate capsule for cigarette

Abstract

The invention relates to a production system for a hollow alginate capsule for a cigarette. The production system comprises an emulsifying tank, a forming device, a separating device, a film forming device, a first water washing device, a solidifying device, a second water washing device and a programmable logic controller (PLC), wherein the emulsifying tank is used for preparing a polyvalent metal ion emulsion; the forming device is used for preparing the polyvalent metal ion emulsion into emulsion drops through a dropping method, and enabling the emulsion drops to contact a forming liquid and condensate, so that a primary pill of the alginate capsule is formed; the separating device is used for separating the primary pill from the forming liquid; the film forming device is used for soaking the primary pill in a film forming liquid for a first preset time; the first water washing device is used for washing the primary pill after being soaked for the first preset time; the solidifying device is used for enabling the primary pill after being washed by water to contact a solidifying liquid for a second preset time; the second water washing device is used for washing the alginate capsule; and the PLC is used for setting the first preset time and the second preset time, controlling the primary pill to be soaked in the film forming liquid for the first preset time, and controlling the primary pill to contact the solidifying liquid for the second preset time. The production system can produce the alginate capsule with the radial size being 2.5mm-4.0mm.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a system for producing hollow alginate capsules for tobacco. Background technique [0002] Most of the soft capsules sold in the market at the millimeter level are produced by pressing or dripping methods, such as vitamin E capsules, cod liver oil capsules, etc. The above-mentioned soft capsule products have the advantages of being easy to carry and take orally. However, most soft capsules use gelatin as the wrapping wall material, which has the following disadvantages: (1) Gelatin is easy to absorb moisture and become soft. Harsh, even after coating and moisture-proof treatment, it is still not resistant to high temperature and high humidity environment; (2) Gelatin is prone to plasticization and hardening; (3) Generally, the preparation of soft capsules requires more complicated equipment and molds. Capsules of 2.5mm-4mm cannot be produced on a large scale due to the difficulty in makin...

Problems solved by technology

The above-mentioned soft capsule products have the advantages of being easy to carry and take orally. However, most soft capsules use gelatin as the wrapping wall material, which has the following disadvantages: (1) Gelatin is easy to absorb moisture and become soft. Harsh, even after coating and moisture-proof treatment, it is still not resistant to high temperature and high humidity environment; (2) Gelatin is prone to plasticization and hardening; (3) Generally, the preparation of soft capsules requires more complicated equipment and molds. 2.5mm-4mm capsules cannot be mass-produced due to the difficulty in making molds; (4) Strict vegetarians and certain religious beliefs reject animal rubber products

However, the preparation technology of the Pickering emulsion droplet template method mainly focuses on the preparation of microcapsules with various structures, and there are few reports on the production and application of capsules with a radial diameter of 2.5mm-4mm.
