Frequently asked questions of top quality Molecular Distillation System for pilot plant test
1.Ask: What's the working principle of Molecular Distillation System?
Answer: Under the condition of negative pressure, heating liquid from the thermostat which makes solution easily separately, magnetic driven scraper is rolling to form a thin film in bottle wall, mixture slowly flow onto bottle wall. This process is characterized by short term exposure of the distillate liquid to high temperatures, by high vacuum pressure (around 1024 mmHg) in the distillation column and a small distance between the evaporator and the condenser around 2 cm, where fluids are in the free molecular flow regime, i.e. the mean free path of molecules is comparable to the size of the equipment. This process has the advantages of avoiding the problem of toxicity that occurs in techniques that use solvents as the separating agent, and also of minimizing losses due to thermal decomposition.
2.Ask: What's the core technology of Molecular Distillation System?
Answer: The key system's tech is to decrease physical tightness between different moleculars distillation system. Adjustable precise temperature is reachable to 250°C. Reliable gas tightness and can maintain a high vacuum degree above 0.1Pa.
3.Ask: What factor decides the experiment outcome of Distillation?
Answer: For same type equipment, mainly includes: 1.Heating liquid's temperature 2.Vacuum degree. 3.Cooling condenser temperature. Material is restricted by its thermal active ability, the heating liquid's temperature may have influence heating-sensitive material when working, so corresponding vacuum degree, heating temperature and cooling condenser temperature are three main
factors for efficiency to get correct separation parameters.
4.Ask:How to select different kinds of Molecular Distillation System?
Answer: 1.According to the solvent's vacuum degree demand, you choose one which has higher vacuum degree in standard configuration. That can reach 0.1Pa.
2.It has Evaporation Surface 1200cm². Also has Evaporation Surface 800cm². Selecting 1200cm² machine is faster in liquid process than 800cm² machine.
5.Ask: What's the feature of Molecular Distillation comparing to other evaporators?
Answer:1.It's better be used in research field to get needed liquid's parameter. It's not very suitable in mass process. 2.Has high vacuum degree which can reach 0.1Pa ~ 50 Pa. 3.Has advantages on dealing with materials that is heat sensitive, of high boiling temperature, belongs to biological acids or lipids. 4. MD may take only few tens of seconds to finish a separation on short path distillatory when it takes hours on a normal evaporation apparatus. 5.For viscid liquid material, you need to pre-heat the material to promote fluidity to accelarate the speed of liquid separation. 6. Your heating temperature range decide to select which heating pump you will use.
6.Ask: How to select vacuum pump for Molecular Distillation System?
Answer: For reaching 0.1Pa vacuum degree demand, you need to choose vane pump with diffusion pump. For above 50Pa vacuum degree, vane pump is enough for operation.
7.Ask: MOQ, Manufacturer, Delivery time, Discount?
Answer: MOQ is one piece. We are manufacturer. Delivery time is 15 workdays. We can offer relative cheaper price according to your order quantity.
