Characteristics of pilot small-scale freeze-drying machine

Characteristics of pilot small-scale freeze-drying machineMain Features

The main feature of the L * a series freeze dryer is the use of PLC instead of the traditional microprocessor used in this type of machine. All industrial freeze dryers use PLC systems. So using the same system in the pilot freeze-drying machine can greatly ensure the reliability and repeatability of the process, while making the equipment comply with cGMP standards.

The control of freeze-drying process through human-machine interface (HMI) mainly includes:

Information display of main components of the system (valves, motors, indicators, etc.)

Alarm information reception

Display of parameters in freeze-drying cycle process

Eliminate the possibility of misoperation

Protecting the system through authorization of the operator

Development of freeze-drying process

Download information through USB interface

The user interface is a very prominent and easy to understand 6.5-inch color touch screen display. Through this touch screen, various parameters of the freeze-drying process can be quickly inputted.

Features of the equipment

flexible application

By using a capping device, the spacing between the layers can be easily adjusted, suitable for bottles of various capacities, sizes, and types. In addition, there is an interface left on the side of the freeze-drying machine for connecting 6-port multi manifold, which can freeze open freeze-drying bottles of CN29/32.

High quality, outstanding craftsmanship

The sample chamber and layer board use the same structure and materials as the industrial freeze dryer. The manufacturing material is 316L stainless steel and all internal components are designed to be easy to clean. The condenser is also made of 316L stainless steel and equipped with an electric heating rapid defrosting device.

The sample chamber and condenser are both equipped with transparent acrylic doors for easy observation of the entire freeze-drying process.

Accurate control, uniform temperature

Sandwich style laminated board with thermal conductive silicone oil circulation channels inside. This structure enables precise temperature control of the product during in-situ pre freezing and sublimation heating stages. The upper layer of heat radiation board is used to ensure that all samples on the board are uniformly heated.

Usually, the vacuum sensor of the freeze-drying machine used in research and development is installed on the vacuum channel to reflect the vacuum degree inside the chamber. The L * a device has a vacuum sensor located inside the chamber, which directly reflects the actual vacuum level of the environment in which the sample is located. This allows for the amplification effect that can be obtained in pilot studies.
