Freezer model, patented lyophilization structure. Changed the traditional complicated operation to prevent material contamination. The drying automation process is suitable for producing quality products. Freezer with programmable heating shelf control and regulation, can control the temperature precisely. Human-computer interface with widescreen LCD display, curve and data make the information of freeze drying process available. Complete pre-freezing and drying process in one machine. The freeze dryer is equipped with viewing windows, and the drying process is intuitive. The process of this equipment is to place vials of liquid material into the freeze drying chamber and then produce a dried powder. Pre-rinsed and dried glass penicillin vials are used, into which the material is poured. Then the vials are capped with special rubber stoppers having side slits in the part that enters the neck of the vial. Corking is made not to the end but by 50%, only to fix the rubber stopper in the neck of the bottle. Subsequently, the liquid is pumped out of the bottle through these slits by vacuum. In the final stage, after complete dehydration of the material is a complete closure of the plug with hydraulic movable shelves. Thus drying takes place in a vacuum environment, and then the material is finally packed in a vacuum. This allows (unlike other types of similar drying) to keep the material in vacuum for a period of 1-2 years. After the bottles are vacuumized the chamber can be opened and automatic or semi-automatic fixing of the rubber stopper with an aluminum cap can be performed. The caps are put on the neck of the vial and sealed. According to the statements of the manufacturer of the equipment, with such technology it is possible to fully restore the viability of the material after dehydration when opening the vacuum packaging within 4-5 hours. Storage in a vacuum of the material is possible at a temperature not exceeding +36 degrees C. Since in the process of dehydration (water removal) the equipment dehydrates the material, the recovery takes place with distilled water. The removed water is frozen in the chamber, then drained after defrosting and it is possible to control how many ml came out of the dried product, in order to restore later exactly the same amount of water. This is an important point. According to the manufacturer’s statements not all materials can be turned into powder, some biological materials when dehydrated turn into a jelly-like substance, which is also recovered with distilled water. The manufacturer of the equipment has a large laboratory, which together with the experienced production can carry out any research of your material, get samples of products in dried form and packed in vacuum for further research by customers.
