Description
Technical field
This utility model relates to a kind of freeze dryer eutectic point eutectic point test equipment.
Background technology
At present, domestic freeze dryer the most all criteria of right and wrong products.What major part manufacturer was walked is imitated road, some factory
Family, while using advanced foreign technology, has been also carried out bigger improvement.As: have employed special guiding device in heating plate,
Make the uniform flow of fluid in plate, it is ensured that heating the most even stable;Water vessel can realize alternately catching water and melting at work
Ice, in water vessel coil pipe, Ammonia refrigeration mode is changed into ammoniacal liquor phase-change-free refrigeration by traditional ammoniacal liquor freezing by change of state, makes water vessel dish
Homogeneous temperature in pipe, frosting is functional.For freeze dryer, these design, improve and optimize, and simply supplement in lyophilizing
Heat sublimation, catch aqueous, improve lyophilizing efficiency;But the lyophilizing mass action for material is the most little.
Ensure quality of material, improve material activity and reproducibility, keep to greatest extent by the cytoactive of dry material with
And by the color of dry material, shape and nutritional labeling, and rehydration performance is good.Lyophylized food be use modern dehydration technique with
Integrating of processes be convenient, health care, the high-quality pollution-free food of pure natural, it is to avoid conventional dehydration method is brought
Variable color, rotten, spoiled, ingredients from lossing, the defect such as cannot reduce.Reduce energy consumption, it is ensured that freeze-drying prods quality is inexorable trend.
The unique counterweight realizing this target controls temperature of charge exactly.The i.e. eutectic point temperature of eutectic point of material.
At present, the instrument volume of domestic and international lyophilizing function tester material eutectic point is big, power consumption is high, somewhat expensive, startup survey
Examination cost is high, supports waste huge.Independent eutectic point MELTING POINT TESTER together, price is the most all at several ten thousand yuan of even hundreds of thousands
The impact of unit, the most restricted cold heating-up temperature and equipment, limitation is too big, and neither one equipment can have eutectic simultaneously
The dual-use function that point is tested with eutectic point.The vacuum freezings such as the medicine of 95%, food, biological product, scientific research, biological preparation
It is dried and all cannot realize the technology lyophilizing that effective temperature controls.All of lyophilizing technique is the most all to grope in constantly experiment
Optimal freeze temperature. a large amount of labor intensive and material resources. vacuum lyophilization is also all in the primary stage.Numerous businessmans is to eutectic
Point eutectic point test is the most all felt frustrated.
Utility model content
The purpose of this utility model is to provide a kind of freeze dryer eutectic point eutectic point test equipment, it is possible to improve existing skill
The problem that art exists, it is achieved vacuum, freezing, be dried, material " eutectic point ", " eutectic point " temperature can be detected again simultaneously
With analysis;And automatically according to " eutectic point " " eutectic point " temperature, lyophilizing technique is arranged temperature control, keep quilt to greatest extent
The cytoactive of dry material and by the color of dry material, shape and rehydration and nutritional labeling, is the most domestic or even state
Market, border all do not have can lyophilization realize the most simultaneously " eutectic point " " eutectic point " test analysis comprehensive vacuum freezing do
Dry analysis system, simple to operate, economical and practical.
