Heat pump characteristics of multi-effect concentrator, Comparison and application of water extract of Chinese medicine


Boiling point of the second effect 4 to 76 / ~ C55 ~ 6060 ~ 64 heating temperature / ~ C60 ~ 64 boiling point of the third efficiency / ~ C48 ~ 52 The first effective heating area of 2639 / m2 2626 second effect condenser cooling area 26 of the third efficiency / rn24633 water consumption (water 25 ℃, water 35 ℃) / (t/195740 can see, just to increase a heating area of 39nl of the single-effect, heat pumps, constant pressure water cascade from the evaporation plant, in the end of the original paste on the installation of efficient collection device, a three-effect concentrator heat pump that transformation was complete. This device has significant energy savings, with a low heat, low temperature evaporation of the special electrical and mechanical information 2009 14 Total No. 224 43 ■ ● equipment, applications and 'E]: F., ~ ~ ZhuangbeiyingyongyuYanjiu point, with the end effect of 1.4 revenue function of the proportion of cream, with evaporation constant, the ability to meet production needs. In particular, this technology can be applied to a multi-effect concentrator, to carry out technological transformation, with less investment and quick returns notable features. 6 Conclusion from 2003 to 2008, Wen brother Valve Co., Ltd. has produced more than 60 sets of heat concentrator and delivery, the situation is that, with concentrated aqueous solution of the heat pump in the concentrator, with the ordinary double-effect, three-way, compared with a low efficiency heating temperature (90 ℃), low boiling point (75 ℃), significant energy saving, water saving and other advantages and significant features of low noise heat pump . with heat pumps used in the pharmaceutical ordinary double-effect, three-effect concentrator technological transformation, making it a double-effect heat pump, heat pump three-effect concentrator,[link widoczny dla zalogowanych], in the case of constant evaporation, energy, water effects are particularly significant. Therefore, concentrator for efficient heat pump energy-saving, water saving and low heat, low temperature evaporation of advanced concentrator. Received: 2009.03.03 Author: Xia Yingjie (1942 a), male, Harbin, professorial senior engineers, chief engineer, research direction: traditional Chinese medicine extraction equipment and enrichment equipment and technology and manufacturing. (Continued from page 22) If the concentration of the next step is the production efficiency can not keep up. If the ability to concentrate large extraction capacity is small, then cause the device to waste. Equipment matching should be based on the actual situation of each pharmaceutical company to choose, because the device parameters and the theoretical productivity differences based on different species, do not come under the theory of production performance equipment design and selection of traditional Chinese medicine must be based on their species actual selection. No can do. (4) equipment clean. device is a good cleaning, cleaning that place is dead; (5) maintenance of equipment is good, when the failure occurred, whether manufacturers to facilitate the timely maintenance; ( 6) The equipment design and safety. the production process, maintenance process is designed with safety switches,[link widoczny dla zalogowanych], the existing equipment is still unsafe factors; (7) equipment energy use; ( equipment appearance (height, volume) apply to existing plants. Linyan Hai Pharmaceutical Co., Ltd. Yunnan Biological Wei Valley by more than Erigeron Lianyungang Vocational and technical schools of Chinese medicine pharmaceutical preparations of solid preparation is an important part of preparation,[link widoczny dla zalogowanych], preparation should be the technology of medicine theory, the other Prescription drug agent analysis, application and methods of modern science and technology design process route, process technology selection and conditions of such series of pilot studies, and research data to collate and summarize the preparation process to make a scientific, rational, advanced, feasible, so that the development of agents to achieve safe, effective, controllable and stable. design and selection of Chinese equipment should be noted: (1) equipment capacity. equipment capacity whether corporate design capacity consistent with the whole extract the lines of the equipment production whether the ability of coordination; (2) material. and what material contact, the contact will react, corrosion, long-term use if there are any quality problems; (3) process requires the production of means testing,[link widoczny dla zalogowanych], production equipment,[link widoczny dla zalogowanych], pharmaceutical equipment in China is 44 * May 2009 5 Series Training Center Engineer (1) equipment to comply with the latest material on the terms of the requirements of GMP; (2) complete sets of equipment selection should be based on a pilot basis to enlarge the production process, or in accordance with the equipment production of drugs will change the process to bring potential risks; (3) design and selection of equipment to consider hygiene requirements, before the traditional Chinese medicine processing equipment on the environment are higher, because the rich variety of traditional Chinese medicine pre-treatment process, the heavy workload , producing more dust, water and more air is humid, easily confused, pollution and other mass incidents, how quickly do a good job cleaning equipment to reduce the workload, you need to be considered in the selection phase; (4) is constantly refining process of Chinese medicine improvements, so the design and selection of the equipment should be appropriate to set aside some time interfaces for process improvement needs.
