Overview

Pro-6055/6085 domestic freeze-drying machine manufacturer introduction, the domestic freeze-drying machine has a new operating system, one click operation makes it easy for users to use, eliminating the trouble of complex operation. The device has added various protective functions to ensure the smooth completion and effectiveness of freeze-drying.

Product Details

The principle of domestic freeze-drying machine is to use low-temperature freeze-drying method for dehydration treatment. It converts the water in the fluid into ice deposits, and then uses a high-speed rotating fan to blow the ice deposits out of the fluid, and then separates them from the fluid. Its characteristics mainly include low-temperature dehydration, high efficiency, low energy consumption, and no pollution. The domestically produced freeze-drying machine has a new operating system that makes one click operation easy for users and eliminates the hassle of complex operations. The device has added various protective functions to ensure the smooth completion and effectiveness of freeze-drying. Freeze drying machines have strong refrigeration and vacuum control capabilities, good drying effects, quietness, and simple operation. Suitable for freeze-drying of fruits and vegetables, meat, traditional Chinese medicine, bird's nest, cordyceps, tea, flowers, pet food, milk, and dairy products. The device is made of 304 stainless steel to meet food safety requirements. It is safe and easy to use, making it a great helper for freeze-drying.

Detailed explanation of the operation of domestic freeze-drying machines:

Firstly, ensure that the internal space of the freeze dryer is clean and free of debris;

2. Check the connection status of each component of the freeze-drying machine;

3. According to the job requirements, select the operating mode of the freeze dryer and adjust the temperature, humidity, and vacuum degree;

4. Check the main control screen of the freeze dryer and set the working time;

5. Clean the exterior and filter of the freeze-drying machine;

6. Start the freeze dryer and operate it according to the operating procedures;

7. Check the operating status of the freeze-drying machine and perform regular maintenance and upkeep;

8. After the freeze dryer is completed, turn off the freeze dryer and collect its refrigerant.

　　Domestic freeze dryerThe typical freeze-drying process can be divided into three stages: freezing, primary drying, and secondary drying. In a properly controlled freeze-drying process, the product temperature must be kept sufficiently low throughout the entire process to prevent structural changes in the dried product matrix, which can have a negative impact on the appearance and properties of the final product. In response to higher requirements for sample processing, the Pro series laboratory freeze dryer has developed a professional Lyo S operating system, which realizes a series of functions such as vacuum control, sample temperature simulation, main drying, and secondary drying program operation, making the equipment more intelligent and making freeze-dried samples easier and more controllable.

　　Features of domestic freeze-drying machine:

　　High precision sensors provide more accurate data----0.001-1000mbar high-precision Pirani sensor, with adjustable and controllable vacuum degree across the entire range, avoiding sample problems such as foaming, bottle blowing, and ice nucleation caused by uncontrollable vacuum. It can accelerate the freeze-drying speed through reasonable vacuum control;

　　Advanced refrigeration system for faster cooling----Rapid cooling significantly reduces sample preparation time.

　　Dual solenoid valves for more precise vacuum control----The vacuum control and pressure relief are separately and independently controlled, which can achieve precise control of the vacuum degree. The system indirectly controls the sublimation temperature of the sample surface through the saturation vapor pressure curve of water.

　　Sample temperature simulation, intelligent recommendation of optimal freeze-drying conditions----The software fits the saturated vapor pressure curve of ice water, and the device simulates the interface sublimation temperature of the sample during the freeze-drying process. Compared with the ineffective design of traditional laboratory temperature probes that cannot be inserted into frozen solid samples, this software more intuitively simulates the temperature parameters of the sample during sublimation, and realizes the control and adjustment of the sample temperature, which is more practical and convenient;

　　Freeze drying program, customizable freeze-drying plan----The device can set a freeze-drying program, which includes system preheating, main drying, and secondary drying steps. The vacuum degree and corresponding duration for each step can be independently set to ensure the efficiency and effectiveness of sample freeze-drying. The program can also be started with one click, which is convenient and fast.

　　Automatic pressure relief, more reassuring for samples----Stable intake rate, protecting sample integrity, can be filled with inert gas, providing an oxygen free clean environment.

　　The equipment is equipped with pressure protection devices, making it more reassuring to use----When the ambient temperature of the equipment is too high, the protective device activates to protect the equipment and avoid damage caused by high-voltage operation;

　　One click defrosting, easier to operate----After the experiment is completed, it can be started with one click to automatically heat the cold trap coil and quickly remove ice from the cold trap;

　　Operator password permissions make the instrument more secure----Strengthen the management of the use of freeze-drying machines; The equipment records the running time, maintenance time, and pump oil replacement time for easy maintenance and upkeep;
