Description

A kind of drying technics of fresh fructus momordicae
Technical field
The present invention relates to Momordica grosvenori, specifically is a kind of drying technics of fresh fructus momordicae.
Background technology
Momordica grosvenori is a cucurbitaceous plant, and its ripening fruits is spheroidal or oval spherical, contain rich nutrient substances and a large amount of moisture content, but Momordica grosvenori is to eat and store and transport with the dry fruit form again, and the dry-making method of dried of fresh fructus momordicae roughly has two kinds at present:
A kind of is the Momordica grosvenori of traditional approach baking, and the drying mode of this Momordica grosvenori is the Lo Han Guo fruit with maturation, is respectively charged into portable layer stereo fruit tray frame according to large, medium and small; The propelling of fruit tray frame is had in the barn of quirk, rotary fan, cycle flue, and at burner hearth internal combustion faggot or coal, process quirk and flue are with the air heat of barn; Temperature is increased to 70 ℃~80 ℃; Open rotary fan and make the temperature everywhere in the drying room reach consistent as far as possible, this method simple, coarse, cost is low; Thereby by 99% Momordica grosvenori producer use nowadays; But there are several deficiencies in this roasting mode: the one, and the time that needs is long, and each stove probably needed about 3-5 days; The 2nd, energy consumption is high, this roasting mode be burning with faggot or coal as energy, contaminated environment, and at the bottom of the energy utilization rate, wasted resource greatly; The 3rd, because difference is put in the fruit position, it is inhomogeneous to be heated, thus need adjust up and down the position of fruit tray with manual work, the lost labor, the Momordica grosvenori of baking a large amount of fruits also can occur by burned by this way.Burned fruit is not only the atropurpureus that appears of appearance, and its nutrition meeting the coking material occurred by heavy damage, and the health of human body is impacted.
A kind of in addition is the new technique that some companies adopt, and they adopt microwave dryer usually, and the high-frequency electric field through microwave produces thermalization and a series of materializing procedures such as expanded to Momordica grosvenori internal water molecule and reaches and make the quick-drying purpose of Momordica grosvenori.This mode of production is quick, and energy consumption is low, and the nutriment conservation rate is high in the Momordica grosvenori.But, the several problems of this method ubiquity: the one, though microwave drying can make the inner dehydration of Momordica grosvenori rapidly, because the inner moisture of the Momordica grosvenori of emptying in time; The fruit internal pressure is higher than furnace pressure, " fried fruit " phenomenon occurs, and moisture can not be discharged in time; Also cause the inner sugar part of fruit to be dissolved in the water; " fried sugar " phenomenon occurs, (be that the inner syrup of fruit is together discharged with moisture content, the shop is sprinkled upon the Momordica grosvenori surface) makes the baking loss can reach more than 10%; Have a strong impact on Momordica grosvenori outward appearance and quality, also strengthened production cost.The 2nd, adopt this kind method to carry out the Momordica grosvenori drying; Because Momordica grosvenori interior moisture content height and the epidermis water content is low makes Momordica grosvenori epidermis and inside be under the different temperature, the Momordica grosvenori that comes out of drying often is dry inside good like this; But epidermis does not also have fully dry; As continuing crust is carried out drying, the intensely dark and inner burned situation of fruit external skins then can occur, can not make Momordica grosvenori reach unified aridity with the outside inside.The 3rd, with the Momordica grosvenori that this kind method drying goes out, not durable putting must be packed, otherwise the phenomenon that gets damp again might occur at once, places the incorrect Momordica grosvenori inside that also possibly cause and goes mouldy, and has a strong impact on the quality of Momordica grosvenori, also increased loss greatly.
Summary of the invention
The objective of the invention is for overcoming the deficiency of prior art, and a kind of drying technics of fresh fructus momordicae is provided, the drying Momordica grosvenori of this technology can keep color and luster, fragrance and the nutritional labeling of Momordica grosvenori, and saves the energy, ensures the quality of products.
The technical scheme that realizes the object of the invention is:
A kind of drying technics of fresh fructus momordicae comprises the steps:
