Supersonic wave-intensified far-infrared radiation drying method

Abstract

The invention discloses a supersonic wave-intensified far-infrared radiation drying method. The supersonic wave-intensified far-infrared radiation drying method utilizes far-infrared radiation and supersonic wave radiation to realize drying treatment on a material to be treated. The supersonic wave-intensified far-infrared radiation drying method utilizes supersonic wave-intensified assistantly far-infrared radiation drying, cavitation and mechanical effects produced by supersonic wave produce intensification effects on heat and mass transfer rates and enzymatic inactivation mechanism of the far-infrared radiation, synchronous dehydration and enzymatic inactivation of a material containing a sensitive enzyme-like substance are realized, and based on high-efficiency drying, an effective component or nutrient loss caused by enzymatic browning and appearance and quality deterioration are avoided. Aiming at honeysuckle flower, the supersonic wave-intensified assistantly far-infrared radiation is used for synergetic drying so that moisture-containing solids and heat and mass transfer rates in a cavity are improved, polyphenol oxidase synchronous inactivation efficiency of far-infrared heat effect is improved, high-efficiency and high-quality synchronous dehydration and enzymatic inactivation of honeysuckle flower are realized, a loss of chlorogenic acid in honeysuckle flower is avoided and dried honeysuckle flower quality is improved.

Description

technical field [0001] The invention belongs to the technical field of food and drug drying processing, and in particular relates to a drying method for ultrasonically enhanced far-infrared radiation. Background technique [0002] Drying is an important means of food and medicinal material preservation, and also an important food / medicinal material processing technology. Through the drying technology, most of the water in the food / medicine is removed, so as to reduce the water activity, inhibit the growth and reproduction of microorganisms, and prolong the storage period of the food / medicine. Common drying methods include hot air drying, microwave drying, far-infrared drying, spray drying, superheated steam drying, vacuum freeze drying, etc. Different drying methods have their own advantages and disadvantages for different materials, and can be freely selected according to the actual situation. However, many crops contain sensitive enzymes, such as polyphenol oxidase. When ...

AI Technical Summary

Problems solved by technology

However, there are few studies on the mechanism of FIR blunt enzymes, and there is a lack of mature theoretical basis

FIR drying did not completely solve the problem of the slow water diffusion rate of honeysuckle stamens, nor did it completely inhibit the deterioration of the surface color and the decline of medicinal quality of honeysuckle. Auxiliary measures are needed to increase the internal diffusion rate and the efficiency of inactivated enzymes.
