Description

Drive end is taken back the vegetable dehydrator that changes material-clearing device

Technical field

The invention provides the vegetable dehydrator that a kind of drive end is taken back changes material-clearing device, specifically is the device that utilizes far infrared radiation or hot blast heating that vegetables are dehydrated.

Background technology

At present, the domestic dewatering vegetable dried forms that generally adopts is simple hot air convection drying.Although this drying mode can be taken away water vapour in time, simultaneously can also bring heat energy into material bed depths, make material bed heat distribution be tending towards even, but in order to guarantee rate of drying, hot blast temperature is generally all than higher, be again under normal pressure, to carry out drying, because oxidation is easy to cause a large amount of losses of nutritional labeling such as organic substance and Vc in the vegetables in addition.Product (dry vegetalbe) color and luster is relatively poor, and the nutritional labeling loss is serious, and class is lower.In addition, this drying mode also exists the energy consumption height, problems such as link hand-manipulated is many, production efficiency is low, sanitary condition difference, and its market competitiveness is worse and worse.Therefore, adopt the dry vegetalbe of hot blast heat drying merely, can not satisfy the quality requirement of people dehydrated vegetables.

At the problems referred to above, generally believe and utilize the far infrared radiation heating technique that vegetables are dehydrated, it is a kind of advanced drying process, because Far-infrared Heating is actually material inside is directly heated, make the thermograde of heat identical with the moist gradient direction that hydrone shifts, the heat and mass that helps dry run, weakened the inhibition that thermograde is moved hydrone outward, shorten drying time, reduce the particularly loss of Vc of nutritional labeling in the vegetables, improved the quality of dry vegetalbe greatly.Therefore, we have also developed first generation far infrared vegetable dewaterer voluntarily in 2004, evidence, this equipment has that rate of drying is fast, heat transfer efficiency is high, energy consumption is low, pollution-free, dry vegetalbe quality better, and be easy to realize advantages such as control automatically, and having obtained national inventing patent, the patent No. is: ZL 2004100239733; After setting up driving plate structure and anti-drop device, obtained china national practical new-type patent, the patent No. is respectively: ZL200620081054.6 and ZL200620081056.5; After improving air inducing mode, obtained national inventing patent, the patent No. is: ZL200610042375.X; After far infrared radiation and hot blast heating combination, obtained national inventing patent, the patent No. is: ZL200610043544.1.But, find by further test, the vegetable dehydrator that above-mentioned patent relates to, although adopted the blanking technology 2 times, to accomplish that as far as possible blanking is clean, thorough, but because the adhesion strength between vegetables heat absorption back and the transporting chain plate is bigger, cause partial material to adhere to above the transporting chain plate, cause blanking thorough inadequately.Quilt is baked paste to vegetables residual on the transporting chain plate owing to repeated multiple times is dry, and easy breed bacteria, has had a strong impact on the dried matter product quality of vegetables.

At this problem, we have set up fixed material-clearing device again, and have obtained china national practical new-type patent, and the patent No. is: ZL200820232819.0.But further test is found, because the installation site of this device in drying box fixed, and behind the transporting chain plate upset blanking, the angle of inclination in transportation sprocket place commutation process is uncertain, thereby causes transporting chain plate can not contact fully with the scraper plate of material-clearing device.Though can remove the part sizing, expect that clearly effect is not ideal enough.

Take a broad view of dewatering vegetable industry present situation, be badly in need of a kind of be equipped with its position at drive end can be automatically and the vegetable dehydrator of the swinging material-clearing device that adapts of the angle of inclination of transporting chain plate, even when the adhesion strength between vegetables and transporting chain plate is big, can guarantee that also blanking is clean, thorough, improves the dry vegetalbe quality.
