Industrial Lyophilizer Food/Fruit Vacuum Freeze Drying Machine Vacuum Freeze Dryer of China Supplier
Vacuum freeze-drying, also known as sublimation drying, abbreviated as FD is a way of drying material that will be in the freezing state, at low temperature, in a vacuum sealed environment, that is, to heat the water in the frozen matter directly from a solid to a vapour and to be trapped by a water catcher. the whole system consists of six components, a drying chamber, a condenser(a water catcher), a heating system, a vacuum system, a refrigeration system and an electrical control system.
Vacuum freeze-drying is to freeze the dried goods below the temperature of three-phase point, and then sublimate the solid water (ice) in the goods directly into vapor under the vacuum condition, remove it from the articles, and make the goods dry. After the material is pretreated, it is frozen quickly, then sublimated and dehydrated, and then packed in the post-treatment workshop.Vacuum system establishes low pressure condition for sublimation drying bin,heating system provides sublimation latent heat for material, refrigeration system provides cooling capacity for water catcher and drying bin. The quality requirements of freeze-dried products: unchanged biological activity, uniform appearance, full shape, firm structure,Good rehydration and low residual moisture. In order to obtain high quality products, we should have a comprehensive understanding of the theory and technology of freeze-drying. The freeze-drying process consists of three steps: pre-freezing,sublimation and re-freeze-drying(analytical drying). Reasonable and effective shortening of freeze-drying cycle has obvious economic value in industrial production.
1. The advanced control system ensures the quality of freezedried products.2. Drying chamberwater catcher, vacuum pipeline and other related parts of freeze-dried products are made of sus304 material,which conforms to GMP standard.
3. The refrigeation system adopts low temperature refrigeration, which fully meets the technological requirements of freeze-dried products.
4. The design is standardized and reasonable to ensure easy operation and maintenance.
5. Adopt Two-stage or multi stage vacuum system to ensure the process vacuum requirement in the production process to meet the reasonable freeze-drying time.
6. Low energy consumption design principle, energy saving and environmental protection.
7.Process design according to the reasonable needs of customers.
The freeze-drying system can be divided into contact type and radiation type by heating method. The miniaturized freeze-dryer genera adopts contact type and the largescale chemical industry adopts radiation type. The general freeze-drying system consists of the following parts.
Stainless steel tubesheet or aluminium alloy tubesheet is used to make the surface smooth and the roughness is less than 0.5 µm.The liquid each layer of tubesheet is uniform to ensure uniform supply of heating.
According to the different layout structure, the design structure of the water catcher is different.Generally, spiral or matrix pipes are used,and SUS304 or SUS316 materials are used.
Electricheating or steam heating is adopted. The heating medium can be made of special heat conducting oil or pure water.
In order to improve efficiency and vacuum degree, multiple groups of vacuum pumps are used for combined vacuum pumping or single machine operation independently to ensure the stability and durability of the whole system.
1.Two-stage piston compressor unit or cryogenic screw unit are adopted to ensure the cooling rate and water catching defficiency of freeze-drying system.
2. Multiple protection of the system is beneficial to stable operation.
3. Priority is given to multi-machine parallel connection for refrigeration and energy regulation.
4. New refrigerants are used to meet the requirements of environmental protection.
1. There are two sets of operatingsystems, manual and automatic, for customers to choose
2. The LCD screen is used for direct manual dialogue
3. Automatically record and save freeze-drying data and curves
4. Remote connection and real-time monitoring.
