Embodiment Construction
[0009] The purification process of coating liquid in the production of reconstituted tobacco leaves by papermaking method, such as figure 1 As shown in the flowchart, the steps include:
[0010] 1) Let the leachate flow through the rotary vibrating screen, horizontal screw machine and disc separator (disc machine) in sequence to separate and purify the leachate;
[0011] 2) The leaching solution after separation and purification enters the concentrated evaporator (concentrator) to concentrate, and then enters the blending tank to prepare fresh coating liquid, and pours the prepared coating liquid into the coating on-site tank for coating machine feed;
[0012] 3) The reconstituted tobacco blade base continuously passes through the immersion tank on the coating machine to be coated with the coating liquid; the excess coating liquid on the sheet base is then squeezed out by the pair of rollers and returned to the in-situ coating tank;
[0013] 4) The in-situ coating tank is co...

The invention relates to a purification process of coating fluid during the production of reconstituted tobacco through the paper-making process, which belongs to the technical field of the reconstituted tobacco through the paper-making process. The purification process comprises the following steps: enabling the redundant coating fluid on a coating machine to flow back to a coating local tank to be converged with the coating fluid supplied by an allocation tank in the tank, and enabling the coating fluid in the tank to return into the tank after purification treatment by a horizontal spiral centrifuge connected with the coating local tank for circulating use. In the purification process, the coating local tank is used for supplying the coating fluid for the coating machine, not only the coating fluid supplied by the allocation tank is contained in the tank, but also the coating fluid which flows back from the coating machine is unceasingly collected, thereby enabling the part of the coating fluid to be used in a circulating manner. However, the coating fluid which flows back contains a large number of fine fibers, calcium carbonate and other substances, which are peeled off a film base, the long-term accumulation can enable the coating fluid to become viscous. The horizontal spiral centrifuge is externally arranged beside the coating local tank, thereby unceasingly treating the coating fluid in the local tank by the horizontal spiral centrifuge in the circulating manner, keeping the viscosity of the coating fluid in the tank balanced, upgrading the quality stability of a product and ensuring the smooth proceeding of the whole production process.
Description
technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaves by papermaking method, and in particular relates to a purification process of coating liquid in the production of reconstituted tobacco leaves. Background technique [0002] Coating plays a very important role in the whole production process of reconstituted tobacco leaves by papermaking method, and the physical state and internal quality of the coating liquid play a decisive role in the quality of reconstituted tobacco leaves. However, during the coating process, fine fibers and calcium carbonate peeled off from the reconstituted tobacco blade base are mixed into the recycled coating liquid, which will gradually make the coating liquid viscous. This not only increases the difficulty of coating, but also causes great changes in the appearance and internal quality of the product, and the quality of batches of products has large fluctuations and poor stability. Therefore, tryin...
