Embodiment

[0017] Example: A drying process for cigarette paper filter base paper, the process is as follows: the base paper is continuously dried at a speed of 80-120 m / min in a drying device; the drying temperature is 120°C±5°C, and the steam pressure is 0.8-1MPa , automatically open the drain valve every 30 minutes to release the condensed water in the box for 2 minutes, if necessary, it can be manually opened and released; the base paper after drying maintains 20-25% moisture.

[0018] A cigarette paper filter base paper drying device, the specific structure is as follows: the steam box is divided into an upper box 4 and a lower box 5, the upper and lower boxes are connected through associated connecting rods 16, 18, and the upper and lower boxes are installed There are steam inlet pipes 2, 3, pressure gauges 6, 7, pressure reducing valves 8, 9, and drain valves 10, 11. Base paper inlets and outlets 1 are arranged in the middle of the front and rear end faces of the upper and lower bo...

Abstract

The invention discloses a base paper drying process of a papery cigarette filter tip and a device thereof, belonging to an accessory of a cigarette product and mainly solving the technical problem of drying base paper during producing the papery filter tip. An upper box body (4 is opposite to a lower box body (5), steam inlet pipelines (2, 3), pressure gages (6, 7), pressure reducing valves (8, 9) and water discharging valves (10, 11) are respectively on the upper box body and the lower box body, a base paper inlet and outlet (1) is arranged in the middle of the front end face and the back end face of the upper box body and the lower box body, and paired conveying rollers correspond to the inlet and outlet. The base paper is continuously dried in the drying device at the speed of 80 to 120 m / min. The drying process and the device thereof can be used for drying the base paper of the papery filter tip.

Description

Technical field: [0001] The invention discloses a material drying process and a drying device used therein, in particular to a cigarette paper filter base paper drying process and a device thereof. Background technique: [0002] Modern cigarettes are often equipped with filters at the back. The materials of these filters are various. Now there is a kind of filter that is made of paper. The paper filter and tow filter are processed into a composite filter. for cigarettes. Therefore, one process of processing this kind of paper (often called base paper) is to dry it to maintain a certain moisture content, so as to facilitate the processing and shaping of the next process. [0003] The existing drying method uses a heating porcelain plate to heat the base paper to dry. When the equipment fails and stops, the temperature of the base paper heated by the porcelain plate is often too high, resulting in local burning of the base paper, resulting in greater waste and increased fire ...
