Description

A balanced multiple-effect concentrator for traditional chinese medicine extract

Technical Field

The utility model relates to a concentrator, in particular to a balanced multi-effect concentrator for traditional Chinese medicine extracting solution.

Background

In the production process of traditional Chinese medicine extraction, concentration and drying, in the pharmaceutical production of various departments, the production link with high energy consumption is calculated, the steam consumption in the concentration link is 65-70% of that in the whole extraction workshop, and the technical means of a multi-effect concentrator is generally adopted in the industry to reduce the energy consumption. The conventional triple-effect concentrator realizes energy conservation by twice repeated utilization of secondary steam, the process of materials is that dilute materials to be concentrated enter a first-effect evaporation chamber, a second-effect evaporation chamber and a triple-effect evaporation chamber in parallel, raw steam enters a first-effect heater, secondary steam generated by the first-effect heating chamber enters a second-effect heater, secondary steam generated by the second-effect evaporation chamber enters the triple-effect heater, secondary steam generated by the triple-effect evaporation chamber enters a condenser, and the steam is reused for multiple times through the steam process to realize energy conservation. The main defects are as follows: 1. conventionally, as good energy balance cannot be achieved among three effects, the efficiency of the third effect is very low, the concentration is slow, and users spend equipment cost of the third effect, but the output of the third effect is very low, the three-effect concentration equipment for the traditional Chinese medicine extracting solution cannot be applied in the market, and basically adopts double-effect equipment in the industry, the steam consumption of the three-effect equipment is only 60 percent of that of the two-effect equipment, three-effect equipment or more than three-effect equipment are not used, and energy is greatly wasted; 2. the dilute materials to be concentrated enter the first-effect evaporation chamber, the second-effect evaporation chamber and the third-effect evaporation chamber in parallel, the first-effect evaporation chamber and the third-effect evaporation chamber are all filled with the same batch of materials, the second-effect evaporation chamber and the third-effect evaporation chamber are transferred to the first-effect evaporation chamber to collect paste, liquid cannot be discharged continuously, on one hand, the liquid medicine is heated for a long time, and heat-sensitive cost loss is caused, on the other hand, the materials in the concentration chambers are always at high concentrations, and therefore the efficiency of equipment is obviously reduced.
