Thermal recycling extraction units applies to the extraction, concentration, diacolation, extraction of naphtha, reclaim of the alcohol of the heat sensitive materials. For instance, the traditional process in lines of plants, animals, Chinese traditional medicine, food additive, etc, in which the material is extracted first and condensed later, is changed to the way of extract and condense at the same time. Also, the whole unit can meet the needs of several kinds of extract requirements such as negative, normal and positive pressure, in which the water or alcohol distill process can be applied. Input the Chinese traditional medicine being shredded, prepared, mixed according to prescription into the extraction tank and add the solvent (the kinds of solvent and quantity added should be subjected to the process), of which the quantity is five to ten times that of the medicine, then after marinating it for some time, open the steam valve to heat with the sheaf heating up normally. And after heating up the straight steam (only applied for water and aromatic oil distilling) for a set time of steam and distill, take the distilling liquid with high-temperature continuously from the bottom of distill tank to the duplicate filter (with regard to the medicine with high level filtering requirement, centrifugal filtration and high speed separation should be taken into use) by coarse filtering through the filter between each other, and then into the condense tank to make the condensate formed. And then transport the condensate through liquid collected tank continuously back to the distill tank by pump. After that, the steam generated from the distill tank enters into the heaters thermal resource of evaporator. On heat exchanging in the heater, the condensate enters into the liquid collected tank while the remaining steam also comes into it, which is formed as condensate transporting back to the liquid collected tank, and then the condensate in the tank is taken back into the distill tank by pump as new solvent. All the steam generated by impregnant in this way are formed as condensate by heat exchanging and transported back into the distill tank, and then we can make full use of the indirect steam in the condense process when distilling the liquid. Right in this way, the equipment has perfect performance in the aspects of energy conservation and impregnant balance keeping. 1. Production time shortens as much as *0%. Several times of distill and then condense for the traditional process, but in this process, both the distill and condense processes are centralized in a unit to develop at the same time, of which the time needs 4 to 6hours only at one time. 2. Steam saves as much as above *0%, take the secondary steam generated from the extraction tank as heat resource of the concentrator and feed the chemicals with high temperature into concentrator, for the purpose of least thermal losses. 3. Feeding quantity of impregnant saves as much as *0%. Feed the impregnant for the medicine in the distill tank just for one time to be used circularly in the seal unit. Then the impregnant in the medicals and dregs shall be recycled on the whole (with less than 5 percent of attrition rate), for the purpose of less quantity, small consumption and great decreases of production costs. 4. Medical obtains *0 to *0 percent more than that of traditional process. And for the reason that the impregnant fed at one time can be cycled in big circumfluence to make sure keep the solute concentration in the medical materials and impregnant high grads, the components content of medicinal materials geminates. As a result, we can make great preparation for the quantitative and qualitative measurements of medicine by dissolving the solute quickly from the medicine with the increasing high yield of medicine and its effective constituent. 5. Multi-function for one unit (distill, condense singly and distill while condense), with compact structure and convenient operation. One person could operate the unit, the floor area of which is very little to save the space for the middle tank and the sharing heater with little capital costs as a whole. 6. The whole unit select excellent stainless steel with full-sealing channelization for the purpose of decreasing the environmental pollution, canceling the infiltration of heavy metal and bacteria to meet the need of GMP completely. 7. Since this device runs in the conditions of negative pressure, the extraction temperature can be adjusted randomly between *0 and *0 degree, which may play a good role in the extraction of medicine with the heat sensitivity and polymerization, for the reason that unit is working in negative pressure. 8. The condenser is designed with military technology and especial structure, the heat exchange efficiency of which are 2 or 3 times of conventional products in the markets. 9. All the secondary steam are finally transported back to the extraction tank as new impregnant in the progress of unit, which can prevent from losses even if materials escape during the condense process.
