Example Embodiment

[0038] Example 1

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

[0040] 1) Reproduction of tobacco leaf condensed water filtration: Reproduction of tobacco leaf condensed water filter frame filter, filtrate into reverse osmosis treatment; the number of plate frame filters filter is 200-300

[0041] 2) Reverse osmosis concentration: The condensed water is initially concentrated, the operation pressure is 1.0MPa, the concentration is about 8.5 times, the transmissive is directly discharged or reflected in the production, reverse osmosis concentrate to the maxifice resin Bed for adsorption;

[0042] 3) Fixed bed adsorption: The concentrate is fixed by ROHM HASS at 5BV / h through RoHM HASS. After collecting the split, the effluent is added to the next batch to concentrate, and the end of the adsorption is completed. After the preparation of the eluent is eluted to the bed;

[0043] 4) Vanoidal m...

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...
