Come take a look at the different "composition systems" of the laboratory freeze dryer.
·The refrigeration system of the laboratory freeze dryer
The inner cylinder type cold trap system has uniform frosting, and the defrosting is convenient and rapid. After a few minutes, the whole piece of ice can be taken out, the defrosting time is shortened, and the disinfection stage is immediately entered, because the inner surface is very smooth and has no dead angle. To make disinfection easier and faster. The cold trap door is also made of a high-strength, explosion-proof, transparent PP material. The vacuum trap system of the cold trap is provided with a vacuum system, so that the cold trap captures moisture to a large extent, prevents moisture from entering the vacuum pump freeze-drying bin and the cold trap, and has an isolation valve, which can measure the freeze-drying end point, and can measure the vacuum degree of the front and rear boxes respectively.
Two-stage cascade refrigeration technology, fully enclosed refrigeration compressor, welded refrigeration pipeline manufacturing process, capillary throttling technology. Air cooled or water cooled units are available. The system operates with minimal vibration and noise, making it ideal for use in the laboratory. The compressor has a delayed start function to extend the life of the compressor.
·The vacuum system of the laboratory freeze dryer
The two-stage rotary vane vacuum pump is used to meet the system vacuum and the maintenance cost is small. The vacuum pump has an anti-vacuum oil reverse spray device and a water-oil separation device, and the vacuum degree in the box is automatically adjusted. During the whole freeze-drying process, the vacuum degree in the dry box can be automatically adjusted according to the set value.
·The hydraulic gland system of the laboratory freeze dryer
The bottom of the drying box is equipped with a hydraulic pump station and a cylinder. The cylinder is driven by a hydraulic pump to drive the plate layer to move up and down smoothly. The cylinder is sealed with a Y+O type fluoro rubber + dustproof assembly. The pulsating hydraulic gland system makes the seal good.
·Circulation system of laboratory freeze dryer
The circulation system is composed of a brazed plate heat exchanger and a shielded circulation pump and an electric heating element of a PID control method, and the cold and heat circulating fluid is a low temperature type low viscosity silicone oil. The cold exchanger in the system uses an imported low temperature stainless steel plate heat exchanger. Small size, high efficiency, high reliability and no leakage.
·Laboratory freeze dryer control system
Simulate the running window interface, the image reflects the running status of each component, and displays the current operating parameters of each component in digital form.
·The hydraulic gland system of the laboratory freeze dryer
Automatic glanding can be achieved after lyophilization.
The freeze-drying box body of the laboratory freeze-drying machine is made of 316L stainless steel material welded, polished and externally fixed with reinforcing ribs, and passed the pressure test and is processed by heat preservation. There is a "sandwich" shelf in the oven for the product. The drying oven door is made of high-strength, explosion-proof and transparent PP material, which can clearly and intuitively observe the changes of lyophilized samples during lyophilization.
