Freeze dryer sales welcome open market
It is well known that when using a freeze dryer for the first time, we must thoroughly clean all parts of the dryer. Everyone knows that stainless steel parts are cleaned with ethanol, and organic glass is cleaned with normal saline. Ampoules are cleaned with an ultrasonic cleaner, but what do we need to do before we actually operate the freeze dryer?
Freeze dryer must be pre-frozen before operation, pre-freezing need to prepare a low temperature refrigerator, minus 40 degrees Celsius, or minus 80 degrees Celsius low temperature refrigerator, put the items to be dried in a low temperature refrigerator or liquid nitrogen, generally required About four hours or so, it can be observed directly from the outside. After the article is completely frozen and frozen, the freeze-drying experiment can be performed. The article can be rapidly moved into the freeze dryer tray to ensure the freeze-drying effect.
The host and the vacuum pump are connected by a green vacuum tube. The connection uses international standard clamps. In order to effectively prevent the leakage of air, this type of clamp is specially designed with a sealing rubber ring inside the clamp. It is applied with a proper amount of vacuum grease on the rubber ring, and then clamped with the clamp to make the joint more closely fit. Together, thus effectively preventing air leakage. If there is no clamping clamp, it will cause air leakage, resulting in the dashboard shows a digital display value greater than 20pa when the vacuum is drawn, this time you should check the airtightness of the vacuum pump and freeze dryer glass cover.
There are two power sockets on the right side plate of the freeze dryer mainframe. One is to connect the power cable of the vacuum pump to the host, and then the main power of the second freeze dryer is plugged in.
Before the vacuum pump operates, it must be checked whether the vacuum pump oil is added or it will not operate normally. The oil level must not be lower than the midline of the oil mirror. The vacuum pump has a relatively strong jitter when it is first used, and slowly becomes smooth.
If the air tightness is not good, some vacuum grease should be applied to the sealing rubber ring above the cold trap, the plexiglass cover should be lightly screwed on the rubber ring, and the sealing performance should be tested by opening the vacuum pump. To ensure its closed integrity.
It is reported that the drying of materials is often due to the following reasons: to make the material flowable, easy to handle, easy to store and store, reduce transportation costs, obtain the desired product quality, and so on. In the pharmaceutical industry, the demand for dry equipment in China in the next few years will be huge, and the demand will not increase.
In recent years, considerable progress has been made in the freeze dryer industry, and product quality and after-sales service have also steadily increased. According to experts, the mature level of quality management is also relatively high in industries with higher market maturity, higher social concerns, higher customer requirements, and fiercer competition. Such as freeze dryer industry
The development of freeze dryers also requires energy conservation and comprehensive energy utilization, such as the use of various joint heating methods, transplantation of heat pumps and heat pipe technology, development of solar refrigeration dryers, etc.; and the development of automatic control technology for refrigeration dryers to ensure The realization of optimal operating conditions; In addition, as humans attach importance to environmental protection, improving the environmental protection measures of refrigerated dryers to reduce the leakage of dust and exhaust gas, etc., will also be the need for in-depth research.
China's refrigeration dryer manufacturers must continue to learn from international advanced technology, combined with practical experience, explore new processes, and continue to grow toward large-scale, high-intensity, and high-economy. With the change in market demand, the domestic competitive landscape of large-scale freeze dryers has been broken down, and the manufacturers have grown from the original few to dozens of manufacturers, and the level of product technology has developed rapidly. Compared with foreign products, the gap has increased. The smaller the development of China's heavy-duty refrigeration dryer industry, the world's peers attach great importance to.
The freeze dryer medical industry has a wide range of applications, which can significantly improve the quality and grade of products. However, because it requires vacuum and low temperature conditions, the application costs are higher. Related pharmaceutical companies will be able to rely on the production of vacuum freeze dryers, freeze dryer sales usher in business another spring.
The method of drying the medicine is various, such as drying, boiling, drying, spray drying and vacuum drying, and the ordinary drying method is usually performed at a temperature of 0° C. or higher. The dried products generally have the problem of shrinking the volume and hardening the texture. Most of the volatile components are lost. Some heat-sensitive medicinal materials may be denatured and inactivated. Therefore, there is a big difference in the properties of the dried product compared to that before drying.
Of course, the freeze dryer has the disadvantage of high cost. Because it requires vacuum and low temperature conditions, the vacuum freeze dryer is equipped with a vacuum system and a cryogenic system, so the investment cost and running cost are relatively high. This point can be seen in the current application of traditional Chinese medicine vacuum freeze-drying more valuable herbs, downstream SMEs when the application of the equipment must be subject to capital affordability.
On the whole, freeze dryers are advanced in their drying methods and have a wide range of applications. Sales of freeze dryers are bound to usher in an open market.
