Description:
The laboratory freeze dryer consists of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components of laboratory freeze dryers are drying ovens, condensers, refrigeration units, vacuum pumps, heating/cooling devices, etc. The principle of the laboratory freeze dryer is to freeze the items to be dried to below the triple point temperature, and then vacuum conditions to make the solid water (ice) in the items directly sublimate into water vapor, and eliminate them from the objects. Items are dry. After the material is pre-treated, it is sent to a quick-freezing chamber for freezing, then sent to a drying warehouse for sublimation and dehydration, and then packaged in a post-processing workshop. The vacuum system establishes a low pressure condition for the sublimation drying chamber, the heating system provides the sublimation latent heat to the material, and the refrigeration system provides the required coldness to the cold trap and the drying chamber. The equipment adopts high-efficiency radiant heating, and the material is heated evenly. The laboratory freeze dryer adopts efficient catching cold trap and can realize rapid defrosting. The high-efficiency vacuum unit can be used to achieve oil-water separation. The parallel centralized cooling system is adopted, and multiple channels are on-demand. Cooling, stable working conditions, and favorable energy conservation; laboratory freeze dryers use artificial intelligence control, high control accuracy, and easy operation. The laboratory freeze dryer has a wide range of applications in bioengineering, pharmaceutical industry, food industry, materials science and deep processing of agricultural and sideline products. The laboratory freeze dryer is suitable for the drying of materials such as high-grade raw materials, Chinese herbal medicines, biological, wild vegetables, dehydrated vegetables, foods, fruits, chemicals, and pharmaceutical intermediates.In general, laboratory freeze dryers use the natural wet state of the adsorbent at an early stage, and it is necessary to gradually establish a regeneration purification adsorption activity after many times. After use for a period of time, adsorption under the effect of pressure will increase the density of the adsorbent and add appropriate conditions according to the adsorbent.
The muffler of the laboratory freeze dryer is regularly maintained and various impurities on the surface of the adsorption surface are removed in time so as not to affect the noise reduction effect and affect the source of the gas. Adjust the throttle opening according to the early dew point. Full of the adsorption dryer filter configuration on the exhaust quality for a long period of time has a great relationship, in the process of system configuration, must be based on professional requirements of different precision filters. To use the laboratory freeze dryer according to the specifications, the ratings within the permissible range are used in various parameters.
Laboratory freeze dryers are used in many applications similar to the precision electronics industry or in high-precision instrumentation because the technical requirements should be that the dew point pressure of the compressed air is below 0°C, and the dew point pressure below 0°C through the laboratory freeze dryer will cause knots to appear. Ice phenomenon, at this time through freeze-drying can not meet the technical requirements, many companies in the introduction of advanced technology, the mechanism of freeze-drying also does not have heat adsorption dryer manufacturing technology, introduced the lowest dew point temperature can reach 70 °C .
The laboratory freeze dryer uses imported high-quality materials, such as manufacturing, to avoid pipeline pollution and improve air quality. In the introduction and absorption of the combined use of the domestic experience, while reducing the consumption of natural gas without heat dryers, the problem of micro-heat dryers and dryers combined to reduce the air compressed air consumption, low consumption volume can reach 5%. To meet the needs of different users.
