Abstract

The invention discloses an extracting liquid concentrating device, comprising a concentrating system, a solvent recovery system and a concentration adjusting system. The device has the advantages that the principle that solvent vapor generated by organic solvent in an outer circulating evaporating separator and fresh steam are heated in a vapor-steam mode through a secondary heater is utilized; for concentration of aqueous extract, a secondary steam and the fresh steam are subjected to steam-steam mixed heating, and transferred to the outer circulating evaporating separator to serve as a heat source, so as to allow the extracting liquid to maintain a boiling state; part of the steam passing through the heater turns into condensate for preheating the extracting liquid; non-condensable gas of the steam and liquid solvent changing state after heat exchange are recycled properly, the remaining heat thereof is made full use to continue preheating the extracting liquid, and recycling of the organic solvent is realized through a plate heat exchanger; the device is energy-saving, efficient, consumption-reducing, low-cost and low-input during concentration process and concentration process of organic solvent, such as ethanol, and the concentration of the extracting liquid can be adjusted freely during the concentration process.

Description

technical field [0001] The invention relates to the technical field of medicine production, in particular to a feed liquid concentration device. Background technique [0002] The concentration of feed liquid is an indispensable key unit operation in the production of preparations. It is to heat the extract to a boiling state through heat transfer at a certain temperature, and to separate non-volatile or hard-to-volatile substances from volatile solvents to a certain To a certain extent, a concentrated liquid with a certain density is obtained. [0003] At present, in the industrial production process, single-effect, double-effect and multi-effect concentrators are mostly used for the concentration of the extract. In recent years, MVR concentrators have also begun to be applied by a small number of companies. Single-effect or multi-effect concentration equipment is heated by steam interlayer. Its obvious disadvantages are long heat transfer time, high temperature, poor unif...
