Embodiment 1

[0039] The method adopted in the embodiment of this application is as figure 1 As shown, the specific operation is as follows:

[0040] 1) Filtration treatment of reconstituted tobacco condensed water: the reconstituted tobacco condensed water is filtered with a plate and frame filter, and the filtrate enters reverse osmosis treatment; the mesh number of the filter screen of the plate and frame filter is 200-300 mesh;

[0041] 2) Concentration of reverse osmosis: use plate type reverse osmosis membrane equipment to initially concentrate the condensed water, the operating pressure is 1.0MPa, the concentration ratio is about 8.5 times, the permeate is directly discharged or reused in production, and the reverse osmosis concentrate is fixed in a macroporous resin bed for adsorption;

[0042] 3) Fixed bed adsorption: The concentrated liquid passes through the XAD-4 non-polar macroporous resin fixed bed of Rohm Hass Company at a flow rate of 5BV / h, and the effluent is collected an...

Embodiment 2

[0049] The method adopted in the embodiment of this application is as figure 1 As shown, the specific operation is as follows:

[0050] 1) Filtration treatment of reconstituted tobacco condensed water: the reconstituted tobacco condensed water is filtered with a plate and frame filter, and the filtrate enters reverse osmosis treatment; the mesh number of the filter screen of the plate and frame filter is 200-300 mesh;

[0051] 2) Concentration of reverse osmosis: use plate type reverse osmosis membrane equipment to preliminarily concentrate the condensed water, the operating pressure is 1.5MPa, the concentration ratio is about 5.2 times, the permeate is directly discharged or reused in production, and the reverse osmosis concentrate is fixed in a macroporous resin bed for adsorption;

[0052] 3) Fixed bed adsorption: The concentrated liquid passes through the fixed bed of HZ-814 weakly polar macroporous resin of Huazhen Technology Co., Ltd. at a flow rate of 3BV / h. The efflue...

Embodiment 3

[0059] The method adopted in the embodiment of this application is as figure 1 As shown, the specific operation is as follows:

Abstract

The invention provides a recovery method of aroma components in reconstituted tobacco condensed water, eluent formed by the method and application of the eluent. The recovery method comprises the following steps: 1) filtering condensed water generated in a production process of reconstituted tobacco to obtain filtrate; 2) carrying out reverse osmosis concentration on the filtrate to obtain an intercepted concentrated solution containing aroma components; 3) adsorbing the intercepted concentrated solution by an adsorbent; and 4) eluting the adsorbent with an eluent to obtain an eluent rich in aroma components. The recovery method is high in treatment efficiency, low in consumable cost, easy to operate and convenient to use on a large scale.

Description

technical field [0001] The invention relates to the field of reconstituted tobacco leaves, in particular to a method for recovering aroma components in condensed water of reconstituted tobacco leaves, an eluate formed therefrom and uses thereof. Background technique [0002] Papermaking reconstituted tobacco is a popular tobacco reconstituted tobacco manufacturing technology at home and abroad. The vacuum concentration section of the process will produce a large amount of condensed water, which is characterized by large flow, low concentration of organic matter, and complex components. [0003] Condensed water organic matter contains a variety of tobacco neutral aroma components, and the recovery of aroma substances from them can improve resource utilization efficiency, but there is still a lack of mature technology. [0004] The concentration of aroma components in condensed water is low, the energy consumption and cost of rectification and concentration are too high, and l...
