Manufacturing process and equipment for a plant polysaccharide-based airgel cigarette filter

Abstract

The invention discloses a process for producing filters or filter rods of Chinese-style cigarettes. The process comprises the specific steps as follows: a, a gel solution is prepared from raw materials of the cigarette filters and injected into tubular molds, and then the tubular molds carrying the gel solution are conveyed by a conveying device sequentially through a tunnel and pass through a cooling ageing room and a prefreezing curing room for ageing and freezing curing; b, the gel solution subjected to sufficient freezing curing is demoulded, demoulded gel bars are sent into a deep freezing room for further freezing, and deeply frozen semi-finished products are then sent into a vacuum freeze drying bin for drying; finally, the dried semi-finished products are subjected to encapsulation, forming and paper setting in a filter rod winding machine, the cigarette filters are obtained and cut in predetermined length, and the cigarette filter rods are obtained. The prepared cigarette filters or cigarette filter rods have better biodegradability, the degradation rate within 28 d reaches 65%, and the process is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of manufacturing cigarette filter rods or multi-segment filters, and in particular relates to a manufacturing process and equipment of a plant polysaccharide-based airgel cigarette filter. Background technique [0002] Cigarette production has a history of hundreds of years. Smoking is a major problem that endangers human health. It has been confirmed that many diseases are closely related to smoking, such as cardiovascular and cerebrovascular and lung diseases. However, it is impossible to completely ban smoking in the world, so efforts to reduce the toxic and harmful components in cigarettes to reduce the harm of cigarettes to people have become a last resort. As a bridge between the smoker and the mainstream smoke, the cigarette filter not only plays a decorative role, but more importantly, it can reduce the smoke, tar, and suspended particles produced during smoking, and can also reduce the harmfulness o...

Problems solved by technology

However, these two fiber materials are difficult to biodegrade and cause pollution to the environment.

In recent years, there are also some patents such as CN1399923A, CN104905409A, etc., which add natural materials such as chitin and corn starch to cellulose acetate to make cigarette filters. The addition of these natural materials can effectively improve the adsorption performance of cigarette filters and at the same time improve their biodegradation resistance, but still can not completely degrade the filter

Compared with the original patent CN102423132A document of the applicant for this patent, the cigarette filter tip made of konjac polysaccharide as the base material, the airgel tip stick obtained by this method has better biodegradability due to the natural polysaccharide as the main material, and can be naturally degraded. The environment will not cause pollution, and the overall filter performance of the filter is good, but the patent does not propose a specific production process and equipment scheme, and large-scale industrial production cannot be carried out
