High equipment stability and extended service life
The vacuum dryer has a solid structure, stable and stable operation, and low resistance, so the bearing force at both ends is also small. “The bearings of the advanced vacuum dryer adopt the exposed design, which reduces the use of wearing parts, and there is no wearing parts in the drying chamber.†The vacuum dryer manufacturer introduces that the traditional equipment will bend under its own gravity and lose its concentricity. Degree, and after the problem with the roller bearing under the drying cylinder, the drying cylinder is easily separated from the roller. Once it falls, it is difficult to get the roller again due to its own weight.
However, the drying chamber of the new vacuum dryer is stationary, not rotating. The advanced production technology plus scientific material selection and rigorous quality requirements ensure the high quality and high sealing of the equipment, and the main body has almost no wearing parts. . “The stability of the static drying chamber is definitely better than the traditional rotating type. At the same time as saving electricity, the life is also extended.†Vacuum dryer manufacturers said.
Wide drying range and flexible installation
The advanced vacuum dryer can dry the raw material with the desired water content, and the moisture content of the finished dry material after drying can be adjusted to 5% water content by frequency conversion, which makes the drying range wide and the use range is wider.
Because some new vacuum dryers are small in size, short in length, light in weight, and more flexible and convenient to install, this also solves the problem of limited customer space, saves space for space use, and improves safety factor.
Although the advantages of vacuum dryers have greatly improved the efficiency of pharmaceutical production and saved energy, there are still many problems that should be discussed and resolved by the industry. The author has learned that the vacuum dryers commonly used in the market currently have the following defects, taking a square vacuum dryer as an example.
Uneven material drying
When the equipment is normally produced, according to the process setting time and temperature, when the certain time is reached, the upper and lower materials are not evenly dried. For example, when water vapor hits the inner wall of the tank, it is easy to appear condensation water on the tank wall. In particular, the water drops on the top plate are often dropped into the top material tray, which affects the dry quality of the material.
There is water at the bottom of the tank during the drying process.
The author has learned that when some vacuum drying ovens are running, due to the vacuum state inside the tank, it is impossible to carry negative pressure drainage. Some of the water at the bottom of the tank is re-evaporated twice, and some of them need to be discharged after shutdown, thus prolonging the heating time and affecting the product. quality.
Low drying efficiency
The water vapor evaporated from some vacuum drying oven materials moves by the pressure difference inside the tank formed after pumping. When the drying season is reached, the evaporation speed of the tank slows down due to the evaporation rate, and the water vapor accumulated in the upper layer of the material is further Affect the drying efficiency of materials.
No inert gas protection device
Some dry boxes are not designed with an inert gas protection device, and in order to prevent oxidation of the product in actual production, inert gas is required to protect it.
With an in-house toolroom, injection moulding facility and Class 7 Cleanroom, we offers a unique manufacturing solution. With a flexible approach to manufacturing, we are able to offer sampling and small batch runs all the way through to volume production and post-operative assembly. Likewise, we mould tools that we have manufactured ourselves or are supplied by our customers.
Our quality control systems meet all the requirements of ISO9001 and we embrace continuous improvement to ensure that these standards are maintained and involve.We have built our reputation on our quality and engineering excellence and can provide you with a robust component, designed to reduce post-operations and ease assembly. However, if required we are able to offer a range of post moulding operations and assembly. We are at the forefront of the insert and overmoulding processes and this experience has ensured that we have the capability to incorporate flexibility into the design of the injection moulding tool, thus enabling us to accommodate the wider tolerances of Metal Parts, that are then overmoulded.Our capabilities with the insert and overmoulding processes has enabled us to lead the pace of the trend to replace metal with plastic components. Working closely with our suppliers and customers we have provided intelligently engineered solutions to design and manufacture plastic parts in replacement of metal components. During this engineering developmental work we have confronted many of the technical issues that are faced when doing this, and have engineered solutions. We provide a value added manufacturing solution, whilst maintaining the integrity and stability that a normal metal component would provide.Working with our partners in the medical sector has given us the good manufacturing procedures, to enable us to inspect and package medical components in our cleanroom environment, ensuring that medical device injection moulding components reach our customers contaminate free.
