Description
Technical field
The present invention relates to material drying system, be specifically related to a kind of full-automatic vacuum freeze-drying system.
Background technology
China is large agricultural country, the grain annual production reaches 900,000,000 tons, wherein cereal is 200,000,000 tons, because existing drying equipment can not satisfy the demands, according to statistics, after China's grain harvest in threshing, dry, store, in the process such as transportation loss late up to 15%, considerably beyond 5% standard of FAO's regulation.In these losses, annual because of fail in time dry cause to go mouldy, germinates rot etc. with a toll of more than 5%, the grain loss that just single this link is made reaches 2,500 ten thousand tons, if edible for each person every day 1 jin of grain can supply 6.8 ten thousand people to eat 1 year.Just the dry problem because of China's grain is very outstanding, and central authorities are indication " will concentrate strength on solving the problem of grain drying equipment " once in 1996.After this, central authorities and each place government department all emphasize this problem every year, owing to be subjected to Chinese government good policy guiding and vast market prospect, this has caused the very big interest of domestic and international drying machine manufacturer, but even to this day, the effectiveness of popularizing and promoting of drying machine is very little.Whole nation grain drying machineryization degree is to so far, and mechanization degree only accounts for about 1%, and its basic reason is that dry technology does not pass a test, and can not make the grain operator obtain satisfied interests repayment on dry this link.
Also depositing the active demand that needs deep processing in the tealeaves industry, particularly the drying of tealeaves is being handled.Tea is one of the world's three big beverages, and China is world product tea flow control one big country, and tea exports second big country, and from international demand, Chinese tea is produced and kept steady growth trend always.China's tea is produced per year more than 3,000,000 tons.And, also generally adopting the mode of the low manual processing of production efficiency and mechanization for the processing of tealeaves, drying machine be because of can't realizing a large amount of dry requirements, and can not obtain the excellent popularization application in the Tea Processing industry.
In the deep processing field of agricultural product,, make agricultural product store, transport and sell in each link, because of can't fresh-keepingly rotting owing to there is not a kind of effective dry machine to be used for drying farm products.If any the lichee of the title of " fruit king ", annual production is 130---and between 1,500,000 tons, but annual deep processing amount is no more than 100,000 tons.According to statistics: China produces fruit prods such as mango, longan, banana per year and all reaches 100---more than 3,000,000 tons.Because dry skill falls behind, and can't carry out effective deep processing to agricultural product, make fresh produce in fresh-keeping, storage, cause a large amount of wastes in transit.
Existing the most frequently used drying means has: vacuum freeze-drying method, freeze-drying, steam seasoning, hot-air seasoning, Far-infrared Heating method, micro-wave drying method etc.No matter adopt above-mentioned which kind of method, its common ground is necessary for and makes dried material keep original color, shape and nutrition as far as possible.In order to realize drying to grain, tealeaves and agricultural product etc., the waste of reducing the loss, people are under the principle of above-mentioned drying means, invent and produce many drying equipments, but existing drying equipment, generally exist following shortcoming: 1, arid cycle long, be more than 12 hours general arid cycle; 2, drying area is little, and each dry material is very limited; 3, drying cost height; 4, a drying machine can only be equipped with a drying box.
