Description
Technical field
The present invention relates to a kind of drying process and equipment of Momordica grosvenori.
Background technology
Momordica grosvenori is the fruit of cucurbitaceous plant Momordica grosvenori, be described as " angle fruit " by people, mainly originate in Guilin, fruits nutrition is worth very high, contain abundant vitamin C and glucoside, fructose, glucose, protein, lipid etc., arhat fruity is sweet cool in nature simultaneously, returns lung, large intestine channel, moistens the lung and relieve the cough, the effect promoting the production of body fluid to quench thirst, in addition, confirm through modern medicine study, " Luohan " fruit tea is the desirable replacement beverage of the unsuitable sugar eater such as diabetes, obesity.
Because Momordica grosvenori fresh fruit is difficult for preserving, therefore plantation will be preserved after dry or further the fresh fruit of harvesting deep processing per family, wherein, the patent of invention that furnace drying method is CN1631273 just like publication number, a kind of Momordica grosvenori baking process is disclosed, it is by ripe Lo Han Guo fruit, according to greatly, in, the little movable multi-layer stereoscopic fruit tray frame that is respectively charged into, fruit tray frame is advanced and has quirk, rotary fan, in the barn of double hanging type cycle flue, at stove chamber inner combustion faggot or coal, hot-air is through quirk, barn temperature is increased to 66 DEG C ± 6 DEG C, opening rotary fan makes the temperature in drying room reach uniformity, moving air is discharged the moisture in baking material through the steam vent at barn top, toast 48～55 hours, after cooling, take out.The described method of this invention, because of temperature uniformity in drying room, has solved preferably plantation family adobe kang baking temperature and has not allowed manageable problem, and efficiency is also higher, but the baking time of Momordica grosvenori needs 48～55 hours work consumings time-consuming, and quality is bad.
In order to improve quality, adopt new technique in recent years, also occurred various processing methods.As Chinese patent application 201010556001.6 discloses a kind of method that adopts microwave dryer to process.Fruits and vegetables internal water molecule is produced to thermalization to the high-frequency electric field of the method by microwave and a series of materializing procedures repeatedly such as expanded reach the quick-drying object of fruits and vegetables.Although microwave has, firing rate is fast, drying time is short, energy utilization rate is high and be convenient to the advantages such as control, but only use microwave to be dried, easily produce due to the overheated phenomenons such as burn and food product edges coking, crust and sclerosis that cause, thereby make scrappage large, and the method is more loaded down with trivial details, repeatedly lower the temperature and heat, thereby workload is strengthened.
At present, and for example Chinese patent application 201210281159.6 discloses a kind of vacuum microwave and infrared ray combination method of heat drying repeatedly of adopting, and the method use microwave from inside to external heat, uses infrared ray to heat from outside to inside Momordica grosvenori, although ensured that Momordica grosvenori degree of drying is higher, quality is also higher, but temperature is high, makes economic cost also high, and operation repeatedly, make process loaded down with trivial details, processing capacity is little, and it is large that cost becomes.
How to improve Momordica grosvenori processed finished products rate, improve work flow and Momordica grosvenori dry mass, cost-saving, realizing large-scale industrial production becomes the large problem that industry faces.
Summary of the invention
The present invention seeks in order to overcome the deficiencies in the prior art, a kind of drying process of Momordica grosvenori be provided and improve equipment, to control better Momordica grosvenori process, improving Momordica grosvenori processed finished products rate and quality, cost-saving, realize large-scale industry dry processing Momordica grosvenori.
