Description
Technical field
The present invention relates to the technical field that artificial fermentation prepares Chinese caterpillar fungus bacterial filament, be specifically related to a kind of method for microwave drying that can significantly promote the quality of fermented aweto hypha.
Background technology
Cordyceps sinensis claims again Chinese caterpillar fungus, is China tradition rare Chinese medicine, has cough-relieving, reduces phlegm, reduces serum cholesterol, adjusting and enhancing immunity, the multiple pharmacological effect such as antitumor.In recent years, both at home and abroad the Cordyceps sinensis demand is increased severely.But because Cordyceps sinensis has its strict parasitics and special growth geographical environment, the output limited, the medicine source is more in short supply.For alleviating the imbalance between supply and demand in market, artificial fermentation's product of Cordyceps sinensis is more and more important.
When artificial fermentation prepares Chinese caterpillar fungus bacterial filament, need by mycelia and separation of fermentative broth mycelia part drying and crushing after fermentation ends.Prior art is general adopts traditional oven drying, or first utilizes that to dry tunnel predrying by it, and then with fluidized drying by its bone dry.The heating-up temperature of these methods is difficult to control, very easily that Chinese caterpillar fungus bacterial filament to be dried is burned, the roasting paste, thereby reduced the medicinal effects of Cordyceps sinensis, and adopt hot blast to be heated, or utilize far infrared quartz fluorescent tube and hot blast to combine and heated, exist heat utilization rate to hang down and the low shortcoming of drying efficiency.
Patent application CN200810019788 discloses a kind of for the fermented cordyceps sinensis mycelia extracting method, it is by the heating that mutually combines of hot air circulation and far infrared fluorescent tube, compare with the extracting method of patent application CN200410037116.9, improved operating efficiency, reduced energy consumption.But the quality of the fermented aweto hypha of its extraction is had a greatly reduced quality, substantially can meet the pharmacopeia specified standard.
Also have prior art to think, adopt the freeze drying fermented aweto hypha, in whole process temperature not higher than fermentation temperature, thereby good maintenance the active principle of metabolism or accumulation in the Cordyceps sinensis sweat.
The freeze-drying method that all relates to fermented aweto hypha in patent application CN200710149371, CN200910197957, the disclosed preparation method of CN201310124056, but quality of the Chinese caterpillar fungus bacterial filament of unexposed gained all.
For solving above-mentioned deficiency, existing prior art report: adopt the microwave drying fermented aweto hypha, can make heating object also become heater, therefore homogeneous heating, can not bake and stick with paste and burned product, and efficient energy-saving, drying time is short, and good practical value and economic worth are arranged.
Patent application CN200710308029 discloses a kind of method for microwave drying of Chinese caterpillar fungus bacterial filament powder, the method is to separate aweto strain from natural cordyceps, final bacterium liquid after repeatedly cultivating, remove filtrate after final bacterium liquid filters and obtain filter cake, it is characterized in that filter cake is removed to moisture with micro-wave drying method, the microwave drying condition is 2450 ± 500Hz, drying time 7-20 minute.But this patent has just roughly been introduced the method for microwave drying of fermented aweto hypha, and wherein the technological parameters such as device therefor, temperature, mode of heating are all undeclared, and the also quality of unexposed gained Chinese caterpillar fungus bacterial filament.
Patent application CN200910101753 discloses a kind of method for microwave drying of fermented cordyceps sinensis mycelia, it is by design tunnel type micro wave baking oven and Drying Technology Parameter thereof, comprise moisture etc. after baking temperature, drying time, hydrofuge frequency and discharging, make the fermented cordyceps sinensis mycelia drying efficiency high, reduce the advantages such as energy consumption and raising end product quality.Although this patent have been described in detail the technological parameter of microwave drying, the quality of the Chinese caterpillar fungus bacterial filament that this technique makes also can meet the pharmacopeia specified standard substantially.Method for microwave drying under this technological parameter still has certain destruction to the quality of Chinese caterpillar fungus bacterial filament as can be seen here.
Summary of the invention
For overcoming the deficiencies in the prior art, the present inventor finds by great many of experiments, method for microwave drying is the workload (kJ/g) that unit sample bears to the core influence factor of fermented aweto hypha, thereby again optimized the method for microwave drying of fermented aweto hypha, obtained that a kind of process stabilizing, drying efficiency are high, product quality is able to the method for microwave drying significantly promoted.
The present invention realizes by the following method:
A kind of method for microwave drying that can significantly promote the quality of fermented aweto hypha, it is characterized in that, after fermentation ends, Cordyceps fermented liquid, through Separation of Solid and Liquid, is got to the solid wet mycelia and is laid on conveyer belt, by the tunnel type micro wave drying oven, carry out drying, the THICKNESS CONTROL of described wet mycelia is at 6～8mm, the speed of described conveyer belt is controlled at 0.2～1.2m/s, and microwave frequency is controlled at 2450 ± 500MHz, and microwave power is controlled at 65～68KW.
Preferably, in above-mentioned method for microwave drying, the THICKNESS CONTROL of described wet mycelia is at 71mm.
Preferably, in above-mentioned method for microwave drying, the speed of described conveyer belt is controlled at 0.5～1.0m/s; 0.8m/s more preferably.
Preferably, in above-mentioned method for microwave drying, described microwave frequency is controlled at 2450MHz.
Preferably, in above-mentioned method for microwave drying, described microwave power is controlled at 66KW.
The invention has the advantages that: in the microwave drying process of fermented aweto hypha, the workload born by the control unit sample is to optimal conditions, thereby farthest reduce the destruction of microwave drying process to product quality, brought good economic benefit to the artificial industrialization of Cordyceps sinensis.
