  Chinese laboratory spray freeze-drying machine developed

   

  Spray freeze-drying technology used in drug microencapsulation technology and increasing milk production, especially in the past, mainly depend on the drug microcapsules spray drying technology, but the spray drying process, is a high-temperature drying process, a lot of heat-sensitive drugs , there will be properties or chemical properties change, affecting the actual composition of the drug. The main co-spray freeze-drying spray freezing and freeze drying are two techniques. Compared with the traditional freeze-drying technology, SFD has the following advantages: (1) small spray droplets dispersed quickly immersed in the freezing cold, can weaken the growth of ice crystals, ice crystals reduce the destruction of the liposomes to avoid leakage of drugs and the burst release; (2) frozen samples were vacuum dried to form spherical particles with a porous structure, fluidity, and particle size can be adjusted by changing the spray process.

   

  Chinese laboratory spray freeze-drying machine developed to fill the spray freeze drying equipment in the field of R & D gaps. Fully simulated in the laboratory for freezing spray the whole process can be used for the laboratory to determine the original recipe / formula update, taste screening, assessment of color, stabilizer / emulsifier applications, and the production of shelf-life test sample giving customers the experimental data can be scaled directly applied to industrial production. For heat-sensitive, viscous, active materials and high sugar content of low-temperature drying of materials, such as herbal extracts of natural products, dairy products, biological agents, enzymes, fruit juice, polymer materials.

   

  Laboratory spray freeze-drying machine main features

   

  1, the laboratory spray freeze drying machine to spray drying and vacuum freeze-drying the organic combination of both, the required drying time very short, greatly reducing the traditional vacuum freeze-drying time, and the dried material is powdered solids, spray-freeze-dried items, the original biological, chemical properties essentially the same, easy-to long-term preservation, add water to return to pre-freeze-dried form, and can maintain its original biochemical properties;

   

  2, rapid freezing spray drying compared to the traditional freeze dryer: can easily stick to the wall, containing organic materials for rapid freeze-drying liquid (juice, extract of traditional Chinese medicine, etc.), and the dried product was granular state, fluidity, particle size within a certain range adjustable.

   

  3, the device uses air-cooled condensing closed compressor cooling system, cooling rapidly, freezing temperature was low, strong moisture absorption, temperature, vacuum display are digital, accurate, and intuitive;

   

  4, freezing spray drying items using natural air plus dye-sublimation, to maintain the security of the sample;stable performance, easy operation, low noise;

   

  5, the host is equipped with vacuum power plug, no additional power supply, easy to use;the vacuum connection using the international standard clamp, convenient and reliable;
