Description
Technical field
The invention belongs to the processing technology field that flowers or vegetables among vegetables is drying, be specifically related to the technique of a kind of heat pump-hot air combined dry chrysanthemum.
Background technology
Chrysanthemum is being commonly called as tawny daylily among the people, and its another name has: day lily, tawny daylily etc.According to Compendium of Material Medica introduction: chrysanthemum, Gan Liang, nontoxic, can help digestion, profit every, be usually used in treatment stool band blood, hot urination, spit blood, blood-shot eye illness, yctalopia, nosebleed, trachyphonia is mute, toothache, pulmonary tuberculosis, spitting of blood, ulcer, dysentery, lack of lactation after delivery, the illnesss such as mastitis.Modern medicine is thought, chrysanthemum has good brain tonic, intelligence development, anti-senescence function.Japanese Scientists lists 8 kinds of brain-care foods, and chrysanthemum is classified as first place, therefore is " brain tonic dish " also known as it, very useful to development of fetus, is the potion good medicine of degenerate.Multiple anthraquinone analog compound in chrysanthemum, there are the effects such as heat-clearing, removing toxic substances, diuresis, detumescence, but it should be noted that: fresh chrysanthemum contains colchicin, after colchicin in hemerocallis enters human intestines and stomach, through slowly absorbing, be transformed into a kind of noxious material being oxidation two colchicin in vivo, each edible hemerocallis just can cause poisoning more than 100g (colchicum alkali number reaches 0.1 ~ 0.2mg).Oxidizing ferment kind simultaneously in day lily body is a lot, and the chrysanthemum after harvesting can not preserve for a long time, and yellowish-brown change very easily occurs.Have to pass through heating, make it to decompose.
Therefore how while not destroying chrysanthemum beneficiating ingredient, the pot-life of chrysanthemum can be extended, reduce the content of harmful substance in chrysanthemum simultaneously, reduce energy consumption, enhance productivity, become a great technical barrier.
Heat pump drying is a new and high technology, and it utilizes evaporimeter dry to air cooling-down, reclaims condenser release heat simultaneously.Compared with traditional heated-air drying/vacuum freeze drying, heat pump drying has following advantage: (1) is energy-efficient, and it is energy-conservation generally reaches more than 30%; (2) temperature is adjustable, and automaticity is high; (3) baking temperature is gentleer, and product color is good, and quality is high; (4) effectively can protect internal and external environment, what heat pump adopted is environment-friendly type heat medium, and is sealed in EGR, can not damage atmosphere.At present, heat pump drying is applied to the drying of wood gradually, pottery cures, the field such as textile industry, seed drying and food processing, be applied in dewatering vegetable especially, drying as wild cabbage, garlic etc., but at home, have not been reported in the application of the drying upper heat pump techniques of flowers food (chrysanthemum).In the heat pump drying middle and later periods, because between air and dried material, mass tranfer coefficient diminishes, the removal of residual moisture needs drying time of growing very much and more energy; Importing and exporting air condition due to hothouse changes very little, and sensible heat and the latent heat of evaporimeter absorption moisture are limited, and heat pump operating condition is deteriorated, and heat pump drying becomes the heated-air drying under cryogenic conditions, and dry efficiency significantly declines.
Therefore, heat pump, should as the heater of drying system in whole dry run, and should as dehydrating unit.Combined drying solves one of length of single heat pump drying time, inefficient effective ways.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, the technique of a kind of heat pump-hot air combined dry chrysanthemum is provided.
Heat pump drying is that the latent heat of water vapour condensation release in the waste gas utilizing heat pump dry run to be discharged is converted into sensible heat by condenser, then in order to dried material.In whole dry run, do not have energy loss, energy consumption is low, and power savings advantages is obvious.Heat pump drying is a kind of drying mode of gentleness, and energy-saving effect is remarkable.But in the middle and later periods of drying, because the mass tranfer coefficient between air and dried material diminishes, remove drying time that remaining moisture needs to grow very much and consume more energy.Heat pump-hot air combined drying combines the advantage of heat pump drying and heated-air drying; make up respective shortcoming, reduce energy consumption, and in hot pump dehydration process, material is in low-temperature condition; better protect nutritional labeling and the heat-sensitive materials of chrysanthemum, maintain the color and luster of material, local flavor and form to greatest extent.
Object of the present invention is achieved through the following technical solutions: the technique of a kind of heat pump-hot air combined dry chrysanthemum, and it comprises the following steps:
S1. the selecting of cadmium yellow flower: pluck cadmium yellow flower, remove etching, bloom, color-changing flower, and remove and take the impurity that naked eyes can see;
S2. the pretreatment of chrysanthemum, comprises following sub-step:
S21. soaking and washing: the chrysanthemum picked out in step S1 is adopted 100 ~ 150mg/L ClO 2 solution soaking sterilization, 10 ~ 20min, then use clean water;
S22. sabot: by the chrysanthemum uniform spreading after soaking and washing on pallet, thickness is 3 ~ 4cm;
S23. steam and complete: the chrysanthemum after sabot is put into enzyme-removal machine, under temperature is 90 ~ 95 DEG C of conditions, steam the 30 ~ 90s that completes;
S24. air-cooled: under the chrysanthemum after completing is placed in room temperature, blows 4 ~ 8min with the wind speed of 4.0 ~ 5.0m/s, be cooled to 35 ~ 40 DEG C;
S3. heat pump-hot air combined drying, comprises following sub-step:
S31. heat pump drying: cooled chrysanthemum is pushed hothouse is 35 ~ 45 DEG C in temperature, and hothouse inlet air humidity is 38.0 ~ 43.0%, air velocity is under the condition of 2.0 ~ 2.5m/s, heat pump drying 3.5 ~ 4.5h;
S32. heated-air drying: hot blast temperature is increased to 60 ~ 70 DEG C, air velocity remains unchanged, heated-air drying 1 ~ 2h;
S4. cool detection, comprise following sub-step:
S41. cooling eases back: dried chrysanthemum is put into clean utensil, is placed on air 24 ~ 48h, until cooling eases back;
S42. detect: carrying out water content detection to cooling the chrysanthemum eased back, requiring moisture≤15%;
S5. packing: the chrysanthemum meeting moisture requirement is carried out packing.
Described cadmium yellow flower is for the dry thick length of bar, meat is big and fleshy, flower bud development is full, middle part golden yellow color, and two ends are in green, and during the great Hua that petal longitudinal furrow obviously reduces, this combined drying raw materials technology is best; Described heat pump drying: temperature is 40 DEG C, hothouse inlet air humidity is 40.0%, and air velocity is 2.2m/s, drying time is 4h, described heated-air drying: temperature is 65 DEG C, when drying time is 1.5h, this combined drying technique products obtained therefrom performance optimal; Described point process of assembling, also comprises step environment, packaging material, equipment and staff being carried out to sterilization.
The standard that in the present invention, dry chrysanthemum product need reach, as shown in table 1.
The dry chrysanthemum product standard of table 1
