Background
In the method for detecting the moisture in food and medicine, the moisture of a sample which is easy to oxidize, decompose and has heat sensitivity and a large amount of volatile components is measured by distillation by a toluene method, and the method is better than a drying method in the moisture measurement of the sample.
The water content measuring device used in the method is as follows: the lower part of the measuring device is connected with water saturated toluene and a sample to be tested, and the toluene-water mixed steam is generated by heating. The mixed steam flows upwards into a branch pipe of the measuring device and then obliquely upwards into a main pipe, a channel for the mixed steam to flow upwards and downwards from a condensate liquid is arranged above the main pipe, a moisture collecting measuring pipe with scales is arranged below the main pipe, the mixed steam flows upwards into a condensing pipe and is condensed into a liquid state by cooling water to flow downwards along the wall of the condensing pipe to enter a collecting pipe, toluene and moisture layers are arranged in the collecting pipe, water is gathered below the collecting pipe due to large specific gravity, heating and cooling are stopped to room temperature after collection, and the volume of the water is read out, so that the moisture content of a sample is measured.
However, this device has problems: 1. the condensed liquid water is heated by the mixed steam after exiting the condensation section, so that part of the water is evaporated into gas state to form repeated evaporation-condensation, and the measurement efficiency is reduced; 2. the mixed steam from the branch pipe heats the toluene layer at the upper part of the main pipe and the collecting pipe, the temperature of the toluene layer rises, the collecting pipe is heated by the heat radiation of the ascending branch pipe, and the collecting pipe is mainly cooled by external air to achieve the auxiliary cooling effect (the air cooling effect is poor), so that the water in the collecting pipe has certain instability; 3. the branch pipe goes upward and then is inclined into the main pipe to form an inverted Y shape, the gravity centers of the condensation pipe and the main pipe are deviated from the flask, and the gravity centers are unstable and easy to fall when connection is actually measured; 4. the branch pipe and the main pipe are inverted Y-shaped, so that the storage and the transportation are inconvenient, and the crushing is easy; 5. the moisture collecting device and the condensing pipe are split, and the connecting device is relatively troublesome.
