Abstract
The invention discloses a method for drying chrysanthemum. The method comprises the following steps: 1, cleaning fresh chrysanthemum, and placing the cleaned chrysanthemum in a material tray; 2, putting the material tray provided with the fresh chrysanthemum in a quick-frozen storeroom to make the temperature of the fresh chrysanthemum be reduced to below -5DEG C from normal temperature in 30min; and 3, placing the quick-frozen fresh chrysanthemum in a microwave drier, drying, and finishing drying when the content of water in chrysanthemum is reduced to below 3%. Chrysanthemum dried by the method of the invention has the advantages of color, fragrance and smell maintenance, and good reservation of chlorophyll and vitamins in chrysanthemum.
Description
Technical field
The present invention relates to a kind of drying means of chrysanthemum.
Background technology
The drying process of existing chrysanthemum adopts hot conditions that chrysanthemum is carried out drying mostly; Chemical reaction had taken place in chrysanthemum when the defective of its existence was dry; Chlorophyll, multivitamin in the chrysanthemum are decomposed; Therefore nutrition keeps seldom after dry, causes the color, smell and taste type of chrysanthemum to be changed.
Summary of the invention
The drying means that the purpose of this invention is to provide a kind of chrysanthemum, dried chrysanthemum keep the color, smell and taste type constant, have finely kept chlorophyll and the Multivitamin in the chrysanthemum.
For realizing above-mentioned purpose, technical scheme of the present invention is:
A kind of drying means of chrysanthemum may further comprise the steps:
(1) bright chrysanthemum is cleaned after, the material disc of packing into;
The material disc that (2) bright chrysanthemum will be housed is put into quick freezing repository and is carried out quick-frozen, and bright chrysanthemum was reduced to below-5 ℃ by normal temperature in 30 minutes;
(3) will pass through bright chrysanthemum after the quick-frozen and pack into and carry out drying in the microwave dryer, when the internal moisture of chrysanthemum reduce to 3% finish when following dry.
Preferably, the vacuum of microwave dryer is 30～120pa in the step according to the invention (3), and temperature is-30～-10 ℃, and electromagnetic field intensity is 180～240V/cm when dry.
Preferably; In the middle dry run of step according to the invention (3); Continue dry 2.5～4 hours earlier, when the moisture content in the bright chrysanthemum has removed 75%～80%, adjust the microwave power of microwave dryer according to the drying curve of bright chrysanthemum; Again through 1.5～2 hours, bright chrysanthemum internal moisture is reduced to 3% and is finished drying when following.
Therefore compared with prior art, the present invention has following beneficial effect:
(1) the present invention adopts microwave dryer that chrysanthemum is carried out drying, and drying time is short, and it is higher under vacuum condition, to carry out dry quality; Compare with conventional desivac and can shorten half drying time, energy resource consumption is 20%～50% of conventional freeze-drying, and the chrysanthemum rehydration of the present invention's processing is good; Mouthfeel is good; Kept the original characteristics and the property of medicine of bright chrysanthemum, moisture content is controlled as below 3%, can guarantee the quality more than 24 months through the inflated with nitrogen packaging product;
(2) adjust microwave power gradually according to the variation of drying curve in the step of the present invention (2), can let the chrysanthemum that is dried keep good physical aspect, outward appearance N/D; Pistil does not come off, and the volume of volume when freezing equates that basically color even is consistent; Loose and porous inner surface, rehydration are rapidly and fully.
The specific embodiment
To combine specific embodiment to specify the present invention below, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as to qualification of the present invention.
Embodiment one
