Description
Technical field
The invention belongs to processing of farm products field, a kind of method of steam beating heat pump microwave combining drying Flos Chrysanthemi.
Background technology
Flos Chrysanthemi (Chuju
Chrysanthemum morifolium) it is the head inflorescence of Compositae Chrysanthemum, after drying as tea-drinking or medicinal, it is Anhui Province's Ways of Special Agricultural Products, by Chinese brand name agricultural product and geography symbol product certification.
Flos Chrysanthemi is frequently with the method such as the most drying, hot air drying, microwave drying.Flos Chrysanthemi belongs to heat sensitive material, and in the course of processing, heat volatile ingredient is lost, Flavonoid substances is oxidizable.Natural dry process is simple, but required drying time is oversize, and is easily limited by natural conditions, affects the quality of drying Flos Chrysanthemi, even cause go mouldy, rotten.Patent 200910185783.4 proposes Flos Chrysanthemi and completes hot air combined seasoning without sulfur vapour heat, and hot air drying temperature is more than 60 DEG C, and the jaundice of products obtained therefrom color and luster, volatile oil component loss are big, and shape of product is the best；Meanwhile, in actual production, hot air drying is difficult to disposably be dropped to by Flos Chrysanthemi moisture less than 15%, needs to be dried by Exposure to Sunlight or secondary hot-air to make Flos Chrysanthemi can be only achieved safe moisture.Patent 200910185784.9 proposes Flos Chrysanthemi and dries Rhizoma Nelumbinis without sulfur microwave deactivation of enzyme and close that seasoning, patent 201110132725.2 propose the microwave vacuum drying method of Flos Chrysanthemi, patent 201110085727.0 proposes the heat pump united drying means of microwave vacuum of Flos Chrysanthemi, but the direct drying Flos Chrysanthemi flower of microwave is susceptible to the phenomenons such as petal is shrivelled, petal pistil is easily scattered, and the large quantity of moisture institute of microwave removal simultaneously subfam. Spiraeoideae is big, machine self-heating phenomenon is serious, be unfavorable for industrialized production.Flos Chrysanthemi pistil is big and thick, it is difficult to rapid draing；Flos Chrysanthemi petal is long narrow and thin, easy dehydration；Flos Chrysanthemi the two feature makes Flos Chrysanthemi be dried to be difficult to disposably complete, limit the exploitation of Flos Chrysanthemi drying process.This requires to add in Flos Chrysanthemi dry run the technique that eases back so that carry out after drying after Flos Chrysanthemi hemp nettle stamen moisture is consistent.Patent 201110156706.3 proposes the method for redrying after carrying out green removal on chrysanthemum, relates to spreading for cooling technique, reach 4d whole arid cycle during redrying.
Heat pump drying, has that the thermal efficiency is high, energy-conservation, baking temperature is low, a feature such as dried object quality better and health, be particularly suitable for nutritious, moisture content is high and being dried of the vegetable of thermal sensitivity and Fish material, used the most widely.Heat pump pours nitrogen and is dried and can effectively prevent nutritional labeling from aoxidizing, and delays color to change.Microwave has bactericidal action to wet stock while being dried, and is suitable for the rapid draing of low water-containing materials.In microwave drying process, introduce vacuum drying, there is suppression nutritional labeling Oxidation.
Summary of the invention
It is an object of the invention to overcome prior art defect, it is provided that a kind of method of steam beating heat pump microwave combining drying Flos Chrysanthemi.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of method of steam beating heat pump microwave combining drying Flos Chrysanthemi, it is characterised in that said method comprising the steps of:
(1) choose not damaged, disease-free Flos Chrysanthemi, by size, color grading, with tap water, Flos Chrysanthemi is cleaned up, be filtered to remove moisture standby；
(2) Flos Chrysanthemi of step (1) gained is put into complete in pallet, be paved into 1cm-3cm thick, complete with saturated vapor, time 2min-5min；
(3) Flos Chrysanthemi that step (2) processed is put in dry pallet, be paved into 1cm-3cm thick, be then placed in removal moisture drying in heat pump drying case；
(4) Flos Chrysanthemi that step (3) processed being placed on and ease back in device, ease back 1h-3h, makes Flos Chrysanthemi hemp nettle stamen moisture consistent；
(5) Flos Chrysanthemi that step (4) processed is put in microwave dryer, microwave power 3kw, drying time 6min-10min；Take dried Flos Chrysanthemi, sort, pack.
In described step (3) heat pump drying case, removal moisture drying step is: with 40 DEG C of-50 DEG C of temperature, air velocity 1m/s-3m/s dehumidifying, dehumidify time 1h-2h；Then it is dried 4h-6h in 10 DEG C of-35 DEG C of temperature, makes the moisture of Flos Chrysanthemi reduce to 30%-40%.
The heat pump drying of described step (3) can be filled with nitrogen in drying baker and be dried.
The microwave drying of described step (5) can be carried out under vacuum conditions.
Beneficial effects of the present invention: it is high that the method for steam beating heat pump microwave combining drying Flos Chrysanthemi of the present invention has (1) Heat Pump efficiency, and heat pump pours nitrogen and is dried and can effectively prevent nutritional labeling from aoxidizing, power consumption is few simultaneously, and energy-conservation more than 30%, low cost；(2) whole Flos Chrysanthemi is short for arid cycle, completes in 10h, and work efficiency is high；(3) being dried less than under the low temperature environment of 50 DEG C, gained Flos Chrysanthemi product flower pattern is good, color is yellowish, and nutrient component damages is little；(4) Flos Chrysanthemi finished product total plate count is less than 3000cfu, safety and sanitation；(5) microwave has bactericidal action to wet stock while being dried, and in microwave drying process, introduces vacuum drying, has suppression nutritional labeling Oxidation.
