热回流提取浓缩机组

型号:

机组由提取罐、过滤器、药液泵、加热器、蒸发器、冷凝器、冷却器、油分器、升温器、工控机等组成。     
中药经浸泡加热后,浸出液由泵从提取罐底部泵入外加热器加热。多余泵液切向进入提取罐底部回流,起到局部搅拌作用。
提取液由加热器加热后,经分离浓缩器闪蒸分离。二次蒸汽切向进入提取罐,一方面把热量传给提取罐内溶剂,一方面起搅拌作用。
余气一路进入冷凝器冷成溶剂,回流进入提取罐。一路进入冷凝液升温器进行热交换,使冷凝液温度接近提取罐溶液沸点,余气进入冷凝器。由于溶剂回流量大,药材与溶剂中含溶质的密度保持高梯度,溶质快速溶出。    
由于是一面提取,一面浓缩,且浓缩液不断排出,流程时间大大缩短,仅需4-6小时。
由于能使冷凝液回流温度接近提取罐溶液沸点,能耗低。整个机组为密闭操作,溶剂消耗少。

整个机组由工控机控制,操作程序,加热温度、蒸发温度、回流温度、系统真空压力、提取罐溶剂液面,浓缩液浓度、蒸发浓缩罐液面均能设定和控制,使工艺流程运行可靠、稳定、安全。
因工艺性能好,收膏率提高。且机组能适应真空、常压、正压工艺操作的水提和醇提,特别适应热敏性物料的低温提取、浓缩。机组工艺流程布局合理、紧凑,外形美观、污染小,符合GMP要求。
机组在高效、节能、多功能等方面具有很大优势。   
在综合性能方面处于国内领先地位。它是与国际天然植物药品接轨的现代化工艺装备。我公司也生产普通的手动控制机组,或半自动控制机组,可满足不同客户的需要。
该机组不但具有中草药(干品)提取浓缩的优良功能。还具有强大的能保持鲜活风味的植物鲜品低温提取浓缩功能。如鲜花、芦笋等鲜品的提取浓缩。它已在中药厂、保健品厂等工厂的实际应用中,显示了它强大的功能优势。该机也可用于天然调味品、食品添加剂中有关动物、海洋生物的提取浓缩。

The residual air will enter into the condenser and become solvent,and  after reflux it will enter into the extracting tank.It will enter into the heater for condensed liquid to carry out heat exchange and make the tem perature of condensed liquid approximate to the boiling point of solution in  the extracting tank.Then the residual air will 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 level of solvent in extracting tank, concentration of concentrated 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 hasreasonable 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.
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 shows its powerful function advantages.  
The equipment is also applicable to the extraction and condensation of natural condiments and food additives concerning animals and halobios.
