A defibrating device for producing reconstituted tobacco leaves by dry papermaking

Abstract

The invention relates to a defibering device for reconstituted tobacco production by means of a dry method of paper-making. The defibering device comprises a rough breaker 1, a fine breaker 2, a fiber storage tank 3 and a fiber metering machine 4 which are connected in sequence, wherein the front end of the rough breaker 1 serves as a material inlet, and a material outlet of the fiber metering machine 4 is connected to a forming device for reconstituted tobacco production by means of the dry method of paper-making. The defibering device further comprises an anti-static humidifying device which comprises a high-humidity air generator 5 and high-humidity air pipelines, wherein the output end of the high-humidity air generator 5 is connected to the material inlet of the rough breaker 1 and the material outlet of the fiber metering machine 4 through the high-humidity air pipelines respectively. According to the defibering device, static electricity generated by fibers during defibering and metering conveyance can be effectively reduced, and fiber agglomeration is eliminated.

Description

[0001] The present invention claims the priority of the Chinese invention patent application date of March 10, 2014 and application number CN2014100856500 for a defibrating device for producing reconstituted tobacco leaves by dry-process papermaking. technical field [0002] The invention belongs to the technical field of tobacco material manufacture. Specifically relates to a defibrating device suitable for producing reconstituted tobacco leaves by dry papermaking. Background technique [0003] Reconstituted tobacco leaves are tobacco flakes, also known as recombined tobacco leaves, homogeneous tobacco leaves, mainly composed of tobacco powder fragments, tobacco stems or low-grade tobacco leaves, plus some foreign fibers, adhesives and other additives. Reconstituted tobacco leaves have been widely used in the production of cigarettes as a raw material for tobacco products. They have the characteristics of low cost, good filling performance, and can reduce the tar content in...

Problems solved by technology

[0005] The second is the problem of static electricity, which is also one of the outstanding problems in dry-laid papermaking

Since the dry defibrillation is carried out in the air, the high-speed rotation and friction of the fibers in the air will generate static electricity. If the static electricity on the surface of the fibers accumulates too much, it will form agglomerates, which will affect the dispersion, transportation and molding of the fibers. Usually, the ambient humidity is low. At 50%, the electrostatic phenomenon is more prominent, until it leads to abnormal production

Therefore, the dry-laid papermaking method often needs to add antistatic agents to solve the problem of static electricity when defibrating, but the fibers used to make reconstituted tobacco leaves cannot be added with antistatic agents, otherwise it will affect the taste of cigarettes

The air-laid papermaking method reconstituted tobacco leaf assembly production line, such as the equipment disclosed in Chinese patent application CN201310393610.8, but its content is basically an ordinary production line for producing air-laid paper, and does not propose the dry-laid papermaking method to produce plant fiber pulp for reconstituted tobacco leaves Therefore, the package production line described in this patent is actually not very suitable for the production of dry-laid papermaking reconstituted tobacco leaves, and it is difficult to produce reconstituted tobacco leaves made of a variety of Fiber combined dry-laid papermaking reconstituted tobacco
