Abstract

The utility model provides an apparatus for extracting fragrance components from tobacco, comprising a distillation chamber, an exchange chamber, a collecting chamber and a condensing pipe. The exchange chamber comprises a gas exchange chamber, a distillation return pipe, a collecting return pipe, a distillation chamber branch pipe and a collecting chamber branch pipe. The length of the gas exchange chamber is 12-18 cm, and the length of the corresponding condensing pipe is 20-26 cm. The lower ends of the distillation chamber branch pipe and the collecting chamber branch pipe are respectively curved outward. The apparatus for extracting fragrance components from the tobacco is used for abstracting the fragrance matters of damascenone, ionone, megastigmatrienone, etc., and prepares samples for checking and evaluating cigarette perfuming. The apparatus for extracting fragrance components from the tobacco of the utility model improves the length of the gas exchange chamber and the condensing pipe, improves the extraction rate of the fragrance components, enlarges the horizontal distance between the distillation chamber branch pipe and the collecting chamber branch pipe, does not need to additionally mount the especial heating apparatus when used, is very convenient, meanwhile can use distillation chambers with big volumes, and improves greatly the single abstraction amount.

Description

From tobacco, extract the device of fragrance component

Technical field

The utility model relates to the tobacco analysis technical field, particularly a kind of device that extracts fragrance component from tobacco.

Background technology

Need to use the principle of steam distillation and two-phase extraction in the tobacco analysis field, utilize organic solvent from tobacco, to extract aroma substances such as damascenone, irisone, Megastigmatrienone, for detecting and the sample preparation is carried out in the perfuming cigarette evaluation.(about 8cm) lacks in existing in the world this type of device gas switch room, condenser pipe is corresponding shorter, aroma substance condensation fully, lose morely, cause recovery rate lower, and horizontal range too little (generally about 7～8cm) between distillery arm and the collecting chamber arm, must acquire special heater during use, use inconvenience, the too little volume that also limits distillery of horizontal range between distillery arm and the collecting chamber arm in addition, thus the amount that causes single to extract is less.

Summary of the invention

The purpose of this utility model is to provide a kind of device that extracts fragrance component from tobacco.

For achieving the above object, the utility model is achieved in that

A kind of device that from tobacco, extracts fragrance component, comprise distillery, switch room, collecting chamber and condenser pipe, described switch room comprises gas switch room, distillation and reflux pipe, collects return duct, distillery arm and collecting chamber arm, described gas switch room length is 12-18cm, corresponding described condensation section length is 20-26cm, and described distillery arm and the promising respectively lower end of described collecting chamber arm go out to excurvation.

Preferable, described gas switch room length is 15cm.

Preferable, described condensation section length is 23cm.

Preferable, the horizontal range between described distillery arm and the described collecting chamber arm is 18-20cm.

Preferable, described distillation and reflux pipe and horizontal direction have the angle of inclination of a 25-35 degree, the top of the bottom of described distillation and reflux pipe and described distillery arm interface and described collection return duct and described collecting chamber arm interface keeps level, thereby guaranteed the distillation and reflux pipe and collected difference in height between return duct, make extraction can be continuously, effectively carry out.

The beneficial effects of the utility model are: by improving the length of gas switch room and condenser pipe, make fully condensation of aroma substance, the fragrance component loss is little, recovery rate is greatly improved, by being designed to the lower end respectively, distillery arm and collecting chamber arm go out to excurvation, increase the horizontal range between distillery arm and collecting chamber arm, need not acquire special heater during use, very convenient; Can use simultaneously the distillery of larger volume, the single extracted amount is greatly improved.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described further.

The device that from tobacco, extracts fragrance component shown in Fig. 1-4, comprise the switch room, condenser pipe 6, distillery 7 and collecting chamber 8, described switch room comprises gas switch room 1, distillation and reflux pipe 2, collect return duct 3, distillery arm 4 and collecting chamber arm 5, gas switch room length is 15cm, corresponding condensation section length is 23cm, distillery arm 4 and collecting chamber arm 5 all are that the lower end goes out to excurvation, horizontal range between distillery arm 4 and the collecting chamber arm 5 is 18cm, distillation and reflux pipe 2 is 30 degree with the angle of inclination 0 of horizontal direction, and the lower extreme point A of distillation and reflux pipe 2 and distillery arm 4 interfaces and the upper extreme point B that collects return duct 3 and collecting chamber arm 5 interfaces keep level.Distillery 7 adopts the 500ml round-bottomed flask, and collecting chamber 8 sizes are 5ml.

In collecting chamber 8, add the 4ml organic solvent during use earlier,, then 10 gram tobacco samples are put into distillery 7, add 300ml water as carrene.Distillery 7 is received on the interface of distillery arm 4, collecting chamber 8 is received on the interface of collecting chamber arm 5, with water bath with thermostatic control collecting chamber 8 is heated, adopt-2 ℃ of circulating condensings, treat that organic solvent refluxes after, with electric jacket distillery is heated, keep boiling reflux after 3 hours, stop heating and take off collecting chamber, drying just can obtain required sample.

Experiment shows that the long gas switch room of 15cm can increase about 13% aspect the recovery rate in the gas switch room long than 8cm.
