Problems solved by technology

[0004] Although the existing sandwich-type papermaking reconstituted tobacco leaves can effectively overcome the impact of raw material quality fluctuations on product quality and reduce raw material consumption, it is still difficult to ensure uniform, consistent and stable vertical and horizontal distribution of the middle core layer in actual production
And do not see good solution yet in the prior art

Embodiment 1

[0026] Production of reconstituted tobacco leaves by sandwich papermaking method. Weigh 570kg of tobacco stems, 380kg of tobacco fragments and 50kg of coniferous wood pulp, soak and extract with 8 times the amount of 90°C water, and separate the soluble matter. The insoluble matter is beaten, and the pulp must be copied for later use. The soluble matter is concentrated in vacuum to a density of 1.1-1.2g / cm 3 The concentrate is ready for use. Weigh 100 kg of 20-mesh tobacco powder raw material, add 400 kg of clear water and stir evenly, then add 5 kg of carboxymethyl cellulose to prepare the coating material for the core layer. The prepared slurry is used to make the surface layer. Firstly, the upper layer is made, and then the coating material of the core layer is evenly applied to the upper layer by the coating roller, and then the lower layer is made on the core layer, and finally pressed into a film base. Backcoat the concentrate onto the formed sheet. After drying and ...

Embodiment 2

[0028] Repeat Example 1 with the following differences: Weigh 540 kg of tobacco stems, 360 kg of tobacco chips and 100 kg of wood pulp, soak and extract with 12 times the amount of 60° C. water. Weigh 100 kg of 40-mesh tobacco powder raw material, add 300 kg of clear water and 1 kg of Maillard reaction fragrance, stir evenly, add 5 kg of carboxymethyl cellulose, and prepare the coating material for the core layer.

Abstract

The invention discloses a method for producing reconstituted tobacco by a sandwich type paper making method. The method comprises the following steps that: tobacco raw materials and non-tobacco fiber materials are subjected to soaking extraction by clean water, the soluble matter is prepared into a concentrated solution for standby, the insoluble matter is pulped, and the upper layer of the insoluble matter is paper-made by a cylinder paper machine; tobacco powder is mixed with clean water, a binder and an additive for tobacco and evenly stirred to prepare a sandwich layer coating material; by adopting a roller coating mode, the coating material is evenly coated on the surface of the upper layer to form a sandwich layer; the lower layer is paper-made on the surface of the sandwich layer and pressed to form a film base; and the concentrated solution is coated back on the film base, and subjected to drying and parting cut to prepare the finished product. The method has the advantages of effectively ensuring the even and stable distribution of the middle sandwich layer, improving the utilization rate of the tobacco raw materials and having active actions on the energy conservation and emission reduction in the production of the reconstituted tobacco, along with simple method, low cost and complete utilization of the raw materials.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaves, and in particular relates to a production method of reconstituted tobacco leaves by a sandwich papermaking method. Background technique [0002] Conventional papermaking reconstituted tobacco leaf production technology needs to extract tobacco raw materials (tobacco stems, tobacco leaves, tobacco powder) with water first, and then mix the extracted tobacco raw materials with wood (hemp) pulp and other non-tobacco fibers through high (low) concentration grinding. Pulp is made, and the pulp is made into shape by fourdrinier paper machine, and then squeezed, pre-dried, concentrated and back-coated with tobacco raw material extract, post-dried and cut to make reconstituted tobacco leaves by papermaking method. The reconstituted tobacco leaves produced by this process are greatly affected by factors such as fluctuations in the quality of tobacco raw materials, and the loss of fine...
