Abstract

The invention discloses a double-effect energy-saving evaporation and concentration system, which can be used for preparing Geshan food retention removing particles. The system comprises a first-effect heater, a first-effect evaporator, a second-effect heater, a second-effect evaporator, a condenser and a vacuum pump which are connected in sequence, and further comprises a heating enhancing mechanism. The heating enhancing mechanism comprises a steam supplementing pipe, the first-effect evaporator is connected with the second-effect heater through a steam conveying pipe, the steam supplementing pipe communicates with the steam conveying pipe, and a one-way valve is arranged on the steam supplementing pipe. By using the double-effect energy-saving evaporation and concentration system, steam can be supplemented and added into the double-effect heater so as to increase the steam amount and temperature, so that the concentration efficiency of liquid medicine in the double-effect evaporator is accelerated, the steam in the single-effect evaporator is utilized to achieve the energy-saving effect, and the processing efficiency of the double-effect evaporator is improved.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine production and processing, in particular to a double-effect energy-saving evaporation and concentration system. Background technique [0002] Geshan Xiaoji granule is a Chinese patent medicine used for food stagnation and abdominal distension and pain caused by stagnation of spleen and stomach qi. The production and preparation process of Geshan Xiaoji granule includes extraction, concentration, sedimentation, sterilization and other processes. In the concentration process, since the liquid medicine is a heat-sensitive material, it is unstable and prone to decomposition, polymerization, and oxidation when exposed to heat. Double-effect concentrators are often used for low-temperature vacuum concentration. The double-effect concentrator heats and concentrates the second-effect liquid medicine through the secondary steam generated by the first effect, and achieves the effect of ...
