The unit is composed of extracting tank , 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 the external heater for heating from the bottom of extracting tank.
The extra pump liquid will enter into the bottom of extracting tank to reflow and play its partial mixing effect . After the extracting liquid is heated by the heater , it will be evaporated instantly and separated by the separation concentrator . The twice steam will enter into the extracting tank , transmitting the heat to the solvent in the extracting tank , and also playing 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 exchange and make the temperature of condensed liquid approximate to the boiling point of solution in the extracting tank . Then the residual air 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 , the process is greatly reduced and only requires 4-6 hours.
As the reflow temperature of condensed liquid is approximate to the boiling point of solution in extracting tank , the energy consumption is very low . The whole unit is operated under airproof equipment , so the solve has little consumption .
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 .
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 , multi-function.
As to the comprehensive performance , 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 requirements of customers.
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 .
