Description

Online density measuring mechanism for extractum

Technical Field

The utility model relates to the field of density detection, in particular to an on-line density measuring mechanism for extractum.

Background

In the production process of some extractum products, the density requirement on the extractum is high, and the density of the extractum needs to be monitored at any time in the production process, so that the concentration of the product is stopped when the optimal density is achieved, and the influence of excessive concentration on the quality of the extractum is avoided.

At present, most enterprises need to stop the concentration process of an evaporation tank in the detection of the density of the extract, simultaneously open the evaporation tank together with an atmospheric valve, discharge the extract at the bottom end of the evaporation tank, then use a container to hold the extract into a special measuring cup, and then use a baume meter for measurement. The method not only damages the vacuum degree of the evaporating pot during sampling, but also is complex in operation, and cannot detect the density of the extract in the evaporating pot in real time. And part of enterprises are provided with an online density detector on the evaporating pot, but the detector is few tens of thousands yuan, so that the investment of fixed assets of the enterprises is greatly increased, and huge economic burden is caused. And the online density detector needs to be calibrated regularly, otherwise accumulated errors can occur, and the detection precision is greatly affected.

Chinese patent text: although the on-line density detection of the extractum is realized by the traditional Chinese medicine formula particle concentration on-line sampler (CN 202320617243A), each operation needs to manually operate a valve to flow out the extractum, then the measurement is carried out, and then the extractum flows back to the system through negative pressure. The process can be completed only by operating an operator on site and continuously supervising the device system, so that full-automatic operation cannot be realized, and unmanned control of the whole system cannot be realized conveniently.
