Description
Technical field
The utility model belongs to the dry processing technique field of food and medicine, is specifically related to a kind of drying device of intensified by ultrasonic wave far infrared radiation.
Background technology
Dry is the important means of food and medicinal material preservation, is also important food/processing of crude drugs technology.By dry technology, most of moisture in food/medicinal material is removed, reach the object that reduces water activity, inhibition microbial growth and breeding, prolongation food/medicinal material shelf time.Common drying mode has that heated-air drying, microwave drying, far-infrared ray drying, spraying are dry, superheat steam drying, vacuum freeze drying etc., and different drying means respectively has quality for different materials, can freely select according to actual conditions.But, there are a lot of crops to contain responsive enzyme material, as polyphenol oxidase, be heated when dry, after cell tissue is destroyed, polyphenol oxidase is under aerobic conditions, the phenol that faces position is oxidized to quinone, and quinone is polymerized to brown pigment after forming accumulation very soon, thereby causes Tissue Browning, not only damage fruits and vegetables sense organ, affect product transportation and sales, also can cause the decline of flavour of food products and quality.Polyphenol oxidase is the Major Enzymes that enzymatic browning occurs, and is present in most of fruits and vegetables, flower and botanical, as honeysuckle.
Honeysuckle is the bud of caprifoliaceae plant honeysuckle, has the effects such as clearing heat and detoxicating, antiphlogistic antibacterial.New fresh honeysuckle color is light green, and medical value is high, but cannot Long-term Storage, must be dry in time after adopting.The honeysuckle dry key of guaranteeing the quality is to adopt suitable drying mode.First, the key issue of honeysuckle dehydration is that pistil moisture diffusion is slow, pistil moisture carries out heat and mass by cavity and petal and external environment condition, and it is large that matter heat is transmitted resistance, easily causes the bad change of honeysuckle color and luster and active ingredient to lose in a large number and improve baking temperature; Secondly the key issue that, quality of Flos Lonicerae is degenerated is easy enzymatic browning.The loss late of effective ingredient of honeysuckle chlorogenic acid in conventional drying process reaches 30%～80%, cause product drug effect to reduce, polyphenol oxidase (PPO, Polyphenol oxidase) enzymatic reaction of catalysis is the main path of chlorogenic acid loss, therefore the dry run of honeysuckle is also noted that the problem of blunt enzyme in considering dehydration.
Far infrared radiation (FIR, far-infrared radiation) technology is a kind of energy-efficient novel pollution-free dry technology.The FIR enzyme that can synchronously go out in dry run completes, and compares with conventional heat treating process and method of chemical treatment etc. the enzyme mode of going out, and has advantages of that Quality protection is good, energy utilization rate is high.But, less about the research of the blunt enzyme mechanism of FIR, lack ripe theoretical foundation.FIR is dry does not solve honeysuckle pistil moisture diffusion speed problem slowly completely, fails to suppress completely the bad change of honeysuckle surface color and medicinal quality yet and declines, and needs to adopt ancillary method to improve diffusion inside speed and blunt enzyme efficiency.
