Operational Principle
In terms of working principle, Small Lyophilizer (also commonly known as household freeze dryers or desktop freeze dryers) mainly rely on advanced freeze drying technology, which is an effective method of removing moisture or other solvents from substances through physical processes under low temperature conditions, in order to achieve long-term preservation of items and maintain their original quality. The entire process is divided into three closely connected steps: freezing, primary dryig (sublimation), and secondary dryig (desorption), each of which plays an indispensable role.
Our Products
The specific execution steps are described as follows:
◆ Freezing stage: This step is the foundation of the entire freeze-drying process. Start the refrigeration system of the freeze dryer, which quickly and accurately lowers the temperature inside the dryig chamber to below freezing point, ensuring that the moisture or other solvents inside the substance freeze into solid ice crystals in a short period of time. This process not only helps to maintain the original structure of the substance, but also lays a solid foundation for the subsequent sublimation stage.
◆ Sublimation stage (primary drying): As the vacuum system is activated, the pressure inside the dryig chamber gradually decreases to an extremely low level, creating an ideal vacuum environment. At this stage, solid ice crystals undergo sublimation and transform into water vapor under low temperature and low pressure conditions without going through the liquid stage. These water vapors are then effectively expelled from the machine through carefully designed vacuum pipes, achieving the removal of most of the moisture in the material.
◆ Desorption stage (secondary drying): After the sublimation stage, although most of the water has been removed, there may still be a small amount of bound water or solvents that are difficult to sublime in the substance. At this point, the heating system of the freeze dryer begins to take effect, providing gentle and sustained heat that causes the residual moisture or solvent to desorb at higher temperatures and deeper vacuum levels, ultimately being completely expelled. This process ensures thorough dryig of the substance, further improving its shelf life and quality.
Through the above three carefully designed steps, a small freeze-drying machine can efficiently and safely remove moisture from substances, retain their original flavor, color, nutritional components, and structure, and become an ideal dryig tool for various occasions such as homes, laboratories, and small businesses.
Products Development

Important Indicator
The performance parameters of small lyophilizer are important indicators for measuring its drying efficiency and applicability. Below, we will provide a detailed introduction to the performance parameters of product from several key aspects.
The drying chamber capacity and freezedrying area of they are core parameters that reflect its processing capacity. Generally speaking, the larger the capacity of the dryig room and the wider the freezedrying area, the stronger the processing capacity of the equipment. The common Lyophilizer dryig chamber capacity usually ranges from a few liters to tens of liters, and the freezedrying area ranges from 0.1 square meters to several square meters. The selection of these parameters needs to be balanced based on actual application needs to ensure that the equipment can meet the needs of experiments or production.
Temperature is one of the crucial parameters in the freezedrying process. It typically have a wide temperature range to meet the drying needs of different substances. Generally speaking, the minimum temperature of the equipment can reach -80 ℃ or even lower to meet the drying requirements for low-temperature sensitive substances. At the same time, the temperature control accuracy of the equipment is also very important, which can ensure the accuracy and stability of temperature during the dryig process. High precision temperature control helps to avoid material damage during the dryig process due to excessive temperature changes.
Vacuum degree is another important performance parameter of product. A higher vacuum degree helps to accelerate the sublimation process and improve dryig efficiency. They are typically equipped with high-performance vacuum pumps to ensure the desired vacuum level is achieved during the dryig process. Common types of vacuum pumps include rotary vane vacuum pumps, oil seal vacuum pumps, etc. These vacuum pumps have the characteristics of fast pumping speed, high vacuum degree, and stable operation, which can meet different dryig needs.
Heating power and heating method are key factors affecting the dryig efficiency of product. Appropriate heating power can ensure sufficient heat is provided during the dryig process, promoting the sublimation of ice crystals. The common heating power range ranges from several kilowatts to tens of kilowatts, depending on the model and configuration of the equipment. In terms of heating method, itusually uses electric heating method, which heats the drying chamber through heating elements. This heating method has the advantages of fast heating speed and precise temperature control.
How to disinfect
Disinfection of small freeze-drying machines is an important step to ensure their hygiene and safety. Here are some disinfection methods suitable for small freeze-drying machines:
Physical disinfection method
Steam disinfection
Remove the removable parts (such as trays, condensers, etc.) from the small freeze-drying machine and place them in the steam sterilizer cabinet.
Through the high temperature steam disinfection, pay attention to control the temperature and pressure of the steam to ensure the disinfection effect.
After disinfection is complete, the parts are taken out to dry or blow dry, and then the freeze-dryer is reassembled.
Dry heat disinfection
High temperature oxidation is used to kill bacteria. Place the inside or removable parts of the freeze-dryer in a hot dry environment, such as an oven.
Set the appropriate temperature and time for heating disinfection.
