Vacuum freeze-drying technology, as the core process of modern material dehydration, has demonstrated irreplaceable value in fields such as food, biopharmaceuticals, and chemical engineering due to its sublimation characteristics under low-temperature vacuum environment.YC-3000As an original product of Shanghai Yacheng Instrument&Equipment Co., Ltd., the vacuum freeze dryer has achieved double breakthroughs in drying efficiency and material activity by deeply integrating spray drying and vacuum freeze drying technologies.

1、 Core technical features

1. Low temperature rapid drying

YC-3000Adopting an air-cooled condensing fully enclosed compressor refrigeration system, the cold trap temperature can be as low as-60℃Combined with air natural heating sublimation technology, ensure that the sample is-15℃Complete freeze-drying below. Compared to traditional freeze-drying machines18Drying cycles of more than hours, this equipment processes in a single batch1500mlMaterials only need6Hours, efficiency improvement3Twice. Its ultimate vacuum pressure reaches20Pa(Empty load), effectively promoting ice crystal sublimation and avoiding material denaturation due to prolonged exposure to high temperature environment.

2. Intelligent control system

Equipment equipped with colorLCDTouch screen, real-time display of key parameters such as drying room temperature, peristaltic pump speed, fan frequency, etc. Users can realize automatic operation through preset programs, such as setting spray pressure（2-5BARAdjustable needle frequency and drying chamber pressure curve. This intelligent design not only simplifies the operation process, but also ensures the uniformity of particle size by precisely controlling the atomization process (such as the function of moving the concentric spray head up and down) to meet the large-scale requirements from laboratory to pilot scale.

3. Safe and convenient modular design

The host and vacuum pump are connected by quick release flanges and equipped with internationally recognized standard clamps to reduce manual intervention. The vacuum pump power supply is integrated into the host, without the need for an external power supply, plug and play. The combination of anti backflow oil vacuum pump and low-temperature disinfection and sterilization function effectively prevents cross contamination and extends the service life of the equipment. In addition, the equipment noise is lower than60Decibel, suitable for installation in clean room environments.

2、 Application scenarios and performance advantages

1. Heat sensitive material handling

Regarding easily deactivated materials such as herbal extracts, enzyme preparations, dairy products, etc,YC-3000Inhibiting biochemical reactions through a low-temperature vacuum environment, preserving the original color, aroma, and nutritional components of the material. For example, the rehydration rate of traditional Chinese medicine extract after drying can reach90%The loss rate of active ingredients is lower than5%.

2. Adaptation to high viscosity and sugary materials

The spray head of the equipment adopts a new concentric design, the atomization is not eccentric, and the viscosity can be processed to5000mPa·sIngredients such as honey and jam. The particle size is realized by adjusting the spray pressure and fan frequency10-100μmControllable, with significantly better fluidity than traditional freeze-dried powder.

3. Large scale production support

Single batch processing capacity of standard equipment1500mlCustomized models are available10LCovering laboratory research and development to industrial pilot testing needs. Users include institutions such as the Wuhan Institute of Hydrobiology, Chinese Academy of Sciences, and Coca Cola Company, which have verified its reliability in the fields of biologics, polymer materials, and more.

3、 Industry Value and Outlook

YC-3000The vacuum freeze dryer solves the pain points of low efficiency and high cost of traditional freeze dryers through technological integration and innovation. Its performance price advantage is fully reflected in industries such as pharmaceuticals, food, and chemicals. With the rapid development of the bioeconomy and the big health industry, this device is expected to expand its application scenarios in fields such as cell preservation and special material preparation.
