Wind fast drying, but its penetration capacity is not strong, slower to internal firing rate, surface of material is easily charred during the later stage of drying；It is micro-
The heating of ripple dried material is uneven, and easily product is ftractureed；Changing temperature-pressure-difference and puffing dry with short production cycle, product product compared with
It is good, but have certain requirement to moisture content of material, typically it need to remove certain moisture by predrying；Vacuum dryer
Expensive and slow-drying；Vacuum freeze drying product quality is best, but energy consumption huge drying time is also longer.Utilize difference
The joint of drying mode, it is possible to decrease production cost and production cycle, can also improve product quality, be following to dry industry hair
One important trend of exhibition.
Vitrescence dry technology is a kind of new food drying technology, in the material that the mechanism of this method need to will be dried
Moisture makes the material formation glassy state dissolved in water and water in food in temperature-fall period by control condition.Then appropriate
In the environment of gradually heat up, make vitrescence ice directly distillation removed for vapor, recycling condenser (cold-trap) vapor is cold
It is solidifying, low-temperature material dehydration is obtained dry product.
Compared with traditional dry technology, the technology has the advantages that its is incomparable, is mainly reflected in following four aspects：
(1) product quality of output is significantly improved, and is retained from nutritional ingredient, and form local flavor keeps all being substantially better than traditional drying production
Product.(2) drying efficiency is significantly improved, and the energy consumption of drying process is significantly reduced, and drying process realizes modularization, and parameters can
Control, is easy to the optimization of technique.(3) vitrescence dry technology applicability is extremely wide, wherein comprising fruit, vegetables, meat, and milk etc. is various
Raw-food material, is equally applicable to the production of Chinese medicine and Western medicine.(4) compared with other processing modes, the processing of vitrescence dry technology
Product has best in quality, instant, it is easy to carry, and is good leisure and outdoor food.But there is presently no one kind
Simple in construction and energy quantity-produced is equipped for realizing vitrescence dry technology.
