Shifting rod type infrared vegetable dehydrator

Abstract

The invention provides a shifting rod type infrared vegetable dehydrator. The shifting rod type infrared vegetable dehydrator is characterized that the inner portion of a box body is separated into a plurality of layers through partition plates, a set of conveying devices which is driven by a transmission device to run are arranged inside each layer, a pin shaft correspondingly protrudes towards the inner side from both chain pins of two chains of the same conveying device at intervals, baffle plates are fixed at both ends of a strengthening pipe and panels of chain plates, each chain plate is hung on each pin shaft, protruding out towards the inner sides, of the chains, baffle plates are supported on a guide rail so as to form a groove-shaped material channel, an infrared radiation appliance is arranged on each channel, a material guiding chute is arranged below the tail end of the channel, an air inducing port is formed in the upper portion of the side wall of each layer of the box body and is connected with a draught fan through an air inducing pipe, J-shaped shafting rods are evenly fixed on the end face of each chain wheel, a limiting rod is arranged between each chain wheel, placed below the transmission device, of each conveying device and the inner wall, close to the transmission device, of the box body, a material feeding port is formed in the top portion of the box body, and a material feeding port is formed in the bottom portion of the box body. The shifting rod type infrared vegetable dehydrator is reliable in work, stable in performance, and good in dried vegetable quality.

Description

technical field [0001] The invention provides a lever-type infrared vegetable dehydrator, in particular a device for dehydrating and drying vegetables by heating with infrared radiation. Background technique [0002] At present, the commonly used vegetable dehydration and drying form in China is hot air drying. In order to ensure the drying speed, the temperature of the hot air is generally relatively high, and in addition, the drying is carried out under normal pressure. Due to oxidation, it is easy to cause a large loss of nutrients such as organic matter and Vc in the vegetables, and the color of the dried vegetables will deteriorate. The loss of nutrients is serious. , the grade is lowered. Therefore, the dried vegetables obtained by drying by means of hot air convection can no longer meet people's quality requirements for dehydrated vegetables, and its market competitiveness is also getting worse. [0003] In view of the above problems, people think that using infrare...

However, through further tests, it was found that the rigidity of the chain plate of the vegetable dehydrator involved in patents 201210355063.X and 201310041337.2 is still not ideal; the double-layer chain plate of the vegetable dehydrator involved in patent 201210355063. If still according to the ZL200620081054.6 instruction "Because the width of the conveyor chain plate is slightly larger than the chain pitch, there is a certain amount of overlapping of the conveyor chain plate", because the thickness of the double-layer chain plate is too thick, resulting in two double-layer chain plates When the chain plates are stacked and arranged together to form a trough-shaped material channel, the inclination angle is too large, and it is not easy to replace the front and rear double-layer chain plates. Therefore, the width of the double-layer chain plates can only be smaller than the chain pitch to eliminate the need for each They overlap each other, resulting in material leakage at the joints of each double-layer chain plate; the vegetable dehydrator involved in the patent "reinforced bar chain plate vegetable dehydrator" is located on the hanging plate on the baffle plate of the reinforced bar chain plate. The hole is moved to the center of the reinforcement rod at one end of the baffle, that is, the reinforcement rod chain plate rotates around the axis of the reinforcement rod when it is flipped and blanked. The chain plate of the rod rotates at a certain angle, but since the radius of the reinforcing rod does not change, it is still impossible to make the chain plate of the reinforcing rod alternately replace the front and back
