The Bench-Top Type Freeze Dryer consists of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components are drying ovens, condensers, refrigeration units, vacuum pumps, heating/cooling devices, etc. It works by freezing the dried item to below the triple point temperature and then sublimating the solid water (ice) in the item to water vapor under vacuum conditions, removing it from the item and drying the item. After the material is pretreated, it is sent to the quick freezing warehouse for freezing, and then sent to the drying chamber for sublimation dehydration, and then packaged in the post-treatment workshop. The vacuum system establishes a low pressure condition for the sublimation drying chamber, the heating system provides sublimation latent heat to the material, and the refrigeration system provides the required cooling capacity to the cold trap and the drying chamber. The equipment adopts high-efficiency radiant heating, the material is heated evenly; the high-efficiency water trap is used, and the defrosting can be realized quickly; the high-efficiency vacuum unit can be used to realize the separation of oil and water; the parallel centralized refrigeration system is adopted, and the multi-channel cooling is required on demand. Stable, energy-saving; artificial intelligence control, high control accuracy, easy to operate.
  The quality requirements for freeze-dried products are: constant biological activity, uniform appearance and color, full shape, firm structure, fast dissolution rate and low residual moisture. To obtain high quality products, a comprehensive understanding of the theory and process of lyophilization should be obtained. The lyophilization process consists of three stages of pre-freezing, sublimation and re-freezing. Reasonable and effective shortening of the freeze-drying cycle has obvious economic value in industrial production.

The Bench-Top Type Freeze Dryer is a small in-situ freeze-drying device suitable for the pilot plant of the pharmaceutical factory and a small amount of production. The bench-top type Freeze Dryer can also be used for freeze-drying treatment of food, Chinese herbal medicine, etc. The in-situ freeze-drying technology is The current international advanced structural design prevents the pollution caused by the material transfer process and realizes the automation of dry sublimation. The bench-top type Freeze Dryer has shelf heating and programming functions, can memorize the freeze-drying curve, and is convenient for users to explore the production freeze-drying. Process. Benchtop freeze dryers are available in standard and gland types and are widely used in pharmaceutical plants, food plants, life sciences, and other locations where freeze-drying processes are required.
The bench-top type Freeze Dryer integrates various technologies such as vacuum, refrigeration and drying into a high-tech drying equipment. Not only that, vacuum benchtop freeze dryer technology also involves expertise in multidisciplinary fields such as heat and mass transfer, fluid mechanics, automatic control, food nutrition, bioengineering, and materials science. The bench-top type Freeze Dryer technology achieves dehydration and drying of the product under vacuum and low temperature conditions.
Desktop freeze dryers are mainly divided into refrigeration systems, air systems, drainage systems, and electronic control systems. The working principle is based on air freeze-drying, the cooling air is cooled to a certain dew point temperature by a refrigeration device, thereby analyzing the water in the compressed air, and then using the separator to allow the air to be gas-liquid separated, and The separated moisture is removed by an automatic drain valve to obtain the effect of freezing and dehumidifying. At the same time, the solid particles with a diameter of more than 3 microns and the amount of micro-oil in the compressed air are filtered by the lyophilizer, so that the configuration of the gas source can be cleaned and dried.
The bench-top type Freeze Dryer technology can not only prevent the physical and chemical degeneration of materials during the drying process, but also reduce the damage to living tissues and cell bodies and the death of living cells and viruses. The use of the lyophilization method can concentrate the liquid medicine without changing the color, and the state is loose, and it can be dissolved immediately after adding water, which not only has good stability, but also reduces the chance of contamination, and thus is convenient to transport and can be stored for a longer time.

Bench-Top Type Freeze Dryer technology is mainly used in:
(1) freeze-drying of biological products with poor thermal stability, biochemical products, blood products, genetic engineering products, etc.;
(2) To maintain the structure and activity of biological tissues, the treatment of biological tissues such as cortex, bone, cornea and heart valve for surgery; (3) Coffee to maintain food color, aroma, taste and nutrients, and to quickly rehydrate Freeze-drying of seasonings, meat, seafood, fruits and vegetables;
(4) Application in microcapsule preparation, drug controlled release materials, etc. Processing of health products such as ginseng, royal jelly, and turtles and Chinese herbal preparations to maintain the invariability of fresh substances;
(5) Ultrafine powder functional materials such as: optical fibers, superconducting materials, microwave dielectric materials, magnetic powders, and treatment of catalysts capable of accelerating reaction engineering.
