The dryer is a mechanical device for reducing the moisture of materials by using heat energy, is used for drying objects, enables the moisture in the materials to be vaporized and escaped by heating the dryer so as to obtain solid materials with specified moisture content, and is mostly used in the fruit and vegetable processing link.

Most of the existing feeding devices for dryers have the following problems:

one, current desicator pan feeding pipe is carrying out the in-process of pan feeding to the fruit vegetables, is carrying out unified unloading with a heap of fruit vegetables usually, because the fruit vegetables of unloading are more simultaneously, can produce collision each other at the in-process fruit vegetables that carry out the unloading, and can extrude each other and lead to the fruit vegetables can fully contradict with pan feeding intraductal wall and cause the jam, influence the unloading effect of pan feeding pipe.

Two, current desicator inner wall space is great simultaneously, and the in-process that drops downwards through the pan feeding pipe when fruit vegetables can produce the collision with the desicator inner wall, leads to fruit vegetables surface to produce to collide with, simultaneously because the position of discharging pipe is fixed the setting, leads to fruit vegetables can pile up at a certain position, leads to fruit vegetables to lay inhomogeneously, leads to the bottom fruit of a certain position to receive excessive extrusion to produce once more and warp simultaneously.

Thirdly, the existing fruits and vegetables are directly stacked inside the dryer, in the drying process, the fruits on the heat source side are dried firstly, and then the heat source is transferred to the fruits and vegetables on the opposite side, so that the fruits and vegetables close to the heat source are possibly dried excessively, and meanwhile, the fruits on the lower side cannot contact with air to be decayed due to the fact that the fruits are stacked, and resource waste is caused.

So we have proposed a pan feeding device for desicator, in order to solve in the above-mentioned put forward because the fruit vegetables of unloading simultaneously are more, in-process fruit vegetables can produce collision each other carrying out the unloading, and can extrude each other and lead to fruit vegetables can fully contradict with pan feeding pipe inner wall and cause the jam, lead to fruit vegetables to pile up in a certain position simultaneously, lead to fruit vegetables to lay inhomogeneously, and the bottom fruit that leads to a certain position receives excessive extrusion to produce once more and warp, and can make the fruit vegetables excessively dry near the heat source, simultaneously because fruit can produce and pile up, it is corrupt to lead to the unable air of contacting of fruit of downside to produce, cause the problem of the waste of resource

place and set up a set of infrared sensor between the lower surface of frame 410 and the upper surface that corresponds lower floor's separating pad 440, multiunit infrared sensor all is close to the setting of returning shape frame 330 place side, and multiunit infrared sensor all includes infrared emitter and infrared receiver, vegetables and fruits are at rolling in-process, the infrared emitter that sets up at the lower surface of placing frame 410/separating pad 440's upper surface continuously transmits infrared signal, correspond to set up at separating pad 440 upper surface/place the infrared receiver of frame lower surface and receive intermittent infrared signal, when the receiver that corresponds no longer receives the signal, show that place the completion on this group placing frame 410.

In this application document, because each layer is placed and all is provided with a plurality of division boards 360 between the frame 410, consequently can set up a set of or multiunit infrared sensor according to actual need between the frame 410 of placing of each layer, technical personnel in the art can select and set up according to actual need and the kind of the fruit vegetables that wait to dry, consequently no longer gives details here.

When the fruits and vegetables are placed on the first layer placing frame 410, the driving mechanism 120 stops working automatically, the motor of the driving mechanism stops driving the rotating roller to work, the adjusting mechanism 310 works automatically, the motor of the adjusting mechanism drives the threaded column to rotate, meanwhile, the threaded sleeve 320 drives the shaping frame 330 to rotate, when the shaping frame 330 moves to a proper position, the adjusting mechanism 310 stops working, the feeding through hole formed in the surface of the shaping frame 330 corresponds to the feeding through hole formed in the surface of the limiting plate 340, the rotating roller 210 works again, when the collection is completed, infrared receivers of a plurality of groups of infrared sensors can not receive infrared signals, the rotating roller 210 stops working, the circulating hot air blower 480 works automatically, the fruits and vegetables are dried, the device is simple to operate, and can separate and convey the fruits and vegetables poured into the feeding box 110, prevent that a large amount of fruits and vegetables from producing the collision at the in-process of unloading, realize the even unloading of fruit vegetables, prevent that the fruit vegetables from producing the jam at the in-process mutual extrusion of unloading, the screw thread post can be adjusted the position of thread bush 320 and type frame 330 back simultaneously, arc pad 350 can carry the fruit vegetables simultaneously, the realization is adjusted the delivery position of fruit vegetables, and division board 360 can separate fruit and place, prevent that the fruit vegetables excessively from piling up together and can make the fruit surface contact with steam comprehensively.
