The Dual Formula Hot Reflux Extraction Evaporator is an equipment used for solvent separation and recovery in industrial production processes. It is mainly used in fields such as chemical engineering, pharmaceutical industry, and petrochemical industry to separate useful components from liquid mixtures.

This type of evaporator uses two independent evaporation systems, namely the liquid phase conversion system and the steam reflux system. By precisely controlling temperature, pressure, and flow rate, efficient solvent separation and recovery can be achieved.

Firstly, the liquid phase conversion system heats and evaporates the mixture, converting the useful components in the liquid into gases. Then, the steam reflux system condenses the generated steam back into the liquid to recover the solvent. This thermal reflux process can greatly improve the solvent recovery rate and reduce energy consumption.

The main advantages of a dual heat reflux extraction evaporator include:
1. Efficient performance: By designing and controlling parameters reasonably, efficient solvent separation and recovery can be achieved.
2. Energy saving: Utilizing the principle of thermal reflux to minimize energy consumption to the greatest extent possible.
3. Quality control: It can accurately control the temperature, pressure, and flow rate during the production process, which is conducive to quality control.
4. Easy to operate: The equipment has a simple structure, is easy to operate, and is easy to maintain and clean.

It should be noted that the specific design and application of the dual heat reflux extraction evaporator can be customized according to different production needs. In practical use, it is necessary to choose suitable process parameters and operating conditions based on the specific situation to achieve the best separation effect and economic benefits.

Equipment descriptions

The unit is composed of extracting tank,fitter,liquid pump,heater,evaporator,condenser,cooler,oil separator,heater and industrial control computer etc.
After dipping and heating,the lixiviation liquid of traditional Chinese medicine will be pumped into external heater for heating from the bottom of extracting tank.The extra liquid will enter into the bottom of extracting tank to reflow and play its partial mixing effect.

After the extracting flash liquid is heated by the heater,it will be evaporated instantly and separated by the separation concentrator,The secondary steam will enter into the extracting tank,transmit the heat to the solven in the extracting tank,and also play mixing effect.The residual air will enter into the condenser and become solvent,and after reflux it enter into the extracting tank.It will enter into the heater for condensed liquid to carry out heat extracting tank.It will enter into the heater for condensed liquid to carry out heat extracting and make the temperature of condensed liquid approximate to the boiling point of solution in the extracting tank.Then the residual aire enter into condenser.As the solvent has large reflux quantity,the density of solute in the medicine and solvent keeps high gradient,and the solute will be rapidly dissolved.

The extraction and concentration are synchronous with continuous discharge of concentrated liquid,thus process is greatly reduced and only requires 4-6 hours.

The whole unit is controlled by industrial control computer,through which,heating temperature,evaporation temperature,reflow temperature,system vacuum pressure,liquid and liquid level of evaporation concentrating tank can be set and controlled.Thus the technology process can be operated reliably,stably and safely.

The unit not only has good functions for extraction and concentration of traditional Chinese medicine and Chinese herbal medicine(Dry product),but also has powerful functions for extraction and concentration of fresh plant products at low temperature with fresh flavor preserved,such as the extraction and concentration of flower and asparagus etc fresh products.It has applied in traditional Chinese medicine factories and health product factories,which show its powerful function advantages.The equipment is also applicable to the extraction and condensation of natural condiments and food additives concerning animals and halobios.

As to the comprehensive performance,it is at the leading position in domestic.It is at the leading position in domestic.It is modernized technology equipment keeping pace with international natural plant medicine.Our company can also produce ordinary manual control unit or semi-automatic control unit to satisfy different requirments of customers.

With good technology performance,the ointment-collecting rate is enhanced.Water or alcohol solvent distillation in conditions of negative pressure,normal pressure and positive pressure,especially low-temperature distillation of heat sensitive materials can be made.The process flow of the unit has reasonable and compact layout,beautiful appearance and low pollution,Which is in accordance with GMP requirements.The unit has many advantages such as high efficiency,energy saving,multifunction.

In summary, a dual hot reflux extraction evaporator is an efficient extraction and concentration equipment widely used in fields such as chemical and pharmaceutical industries, for extracting solutes from liquid mixtures and recovering valuable compounds.
