Description

Band drier

Technical field

The utility model relates to a kind of plant equipment, particularly relates to the plant equipment that dehydrates of food such as cassava, Ipomoea batatas, potato block.

Technical background

Cassava is a shrub shape perennial crop.Originate in american torrid zone, introduce China the twenties in 19th century, at first one band cultivation in Gaozhou county, Guangdong Province, introduce Hainan Island subsequently, now be distributed widely in the South China, with Guangxi, Guangdong and Hainan cultivation at most, the southern areas of provinces such as Fujian, Yunnan, Jiangxi, Sichuan and Guizhou are also introduced a fine variety and are planted experimentally.Development along with modern production, cassava becomes food, feed, medicine, fuel oil, alcohol and other industrial primary raw materials, and become the primary raw material of national bioenergy, so cassava naturally and understandably becomes one of large economy crops in rural area, China south.Yet because just the cassava of results contains a large amount of moisture content, if untimely the processing, it is rotten to go rotten, and causes waste and economic loss.Traditional processing mode of cassava slice drying, be that the cassava of results is cut into flat bulk, it is cassava slice, mainly be to rely on the sun of nature to dry, water evaporates in the cassava slice is fallen, but this method can be subjected to the restriction of many-sided factors such as weather, season, threshing ground, manpower dramatically, especially run into for a long time all the time according to, even the date of a run of wet weather, cassava slice has just been suffered disaster, and cool solarization of cassava disperses to assist on the threshing ground on ground, can be stained with dirty thing such as many dusts, bacterium, this brings unnecessary trouble can for the processing work of treatment of postorder.At this situation, the someone has invented some cassava slice dryers, and open source literature has also been reported the equipment of this respect that some are new, for example:

1. Chinese patent: cassava slice dryer, application number: CN200920140478.9, the applying date: 2009.01.23, publication number: CN201349485, open day: 2009.11.25, applicant: Wei Zhijian, address: the old villagers' committee of writing in Nanning City, Guangxi Zhuang Autonomous Region Binyang County bridge town is old write No. 162, village, inventor: Wei Zhijian, this utility model discloses a kind of cassava slice dryer, it comprises cylindrical housing, be located at feed hopper and the hot blast inlet pipe that is located at housing lower end one side above the housing, it is characterized in that: be located at lower end in the described housing, and the porous skew wall bucket that communicates with described hot blast inlet pipe; In housing, positioned at intervals is in some helical stir axles of described housing above and below; The lower end communicates the scavenge trunk that the upper end communicates with porous skew wall bucket inboard with the hot blast inlet pipe and the porous skew wall bucket outside.This dryer, feed hopper above housing is put into the inner chamber of cassava slice to housing, and the cassava slice of hot blast above housing lower end one side blows to by porous skew wall bucket advances heat drying to cassava slice, some helical stir axles constantly rotate the cassava slice in the stirring shell, make it to be heated evenly.Process heated drying efficient height.The whole Fully-mechanized operation of heat drying process to cassava slice, housing and corresponding structure thereof can be by the scale settings of producing.

2. Chinese patent: a kind of cassava slice dryer, application number: CN200920140948.1, the applying date: 2009.06.11, publication number: CN201476499U, open day: 2010.05.19, applicant: Wu Qirong, address: Haicheng District Chongqing, Beihai, Guangxi Zhuang Autonomous Region Lu Rongli garden A301, inventor: Wu Qirong, summary: a kind of cassava slice dryer, it is characterized in that: have drying box, hot-blast stove, be provided with net belt conveyer in the drying box, net belt conveyer mainly comprises drive unit, screen cloth band.The utility model has overcome the dry traditional processing mode that relies on the nature sun to dry of cassava slice, be subjected to the restriction and the not high shortcoming of efficient of many-sided reasons such as weather, season, threshing ground, manpower, can make cassava slice dryer toolization, production efficiency height, power consumption less, cost is low, and simple to operate, easy to maintenance, meet sanitary condition.

Above patent and traditional drying naturally, certain progress has been arranged, yet, the inventor finds that also there are some problems in it, wherein the cassava slice dryer of document 1 adopts some helical stir axles constantly to rotate the stirring cassava slice at inner chamber, produce collision and friction between the cassava slice in the housing, can make the cassava slice breakage; Though the structure in document 2 housings is more reasonable,, there are same defective in it and document 1, the one, and its charging is adopted and is manually directly poured in the casing of drying plant, and phenomenon of blocking often takes place at charging aperture in cassava slice; The 2nd, because discharging is to discharge naturally in the bottom of housing, so equipment must be installed in higher position, otherwise, cassava slice can be deposited in together, needs the timely combing of operator, can increase working strength of workers like this, thermal loss is big, the modern large-scale production of incompatibility.
