Continuous infrared drying machine for fruits and vegetables

Abstract

The invention discloses a continuous fruit and vegetable infrared drying machine which comprises a fixed machine base, a charging barrel is rotationally installed on the fixed machine base and driven by a rotary power device, a sliding support is installed on the fixed machine base in a sliding mode, a lamp box assembly is fixed to the sliding support and comprises a box body, and an air chamber is arranged on the box body. An air inlet pipe is fixed to one end of the box body, an air supply fan is installed on the sliding support, an air distribution pipe is fixed in the air chamber, air distribution holes are formed in the air distribution pipe, an air uniformizing plate is installed on the box body and located below the air distribution pipe, a plurality of distribution holes are formed in the air uniformizing plate, and an air cooling cavity defined by a heat insulation flow uniformizing plate is installed below the air uniformizing plate. Air outlet holes are evenly formed in the heat insulation flow equalizing plate, and a plurality of infrared heating lamp tubes are installed on the box body. According to the continuous fruit and vegetable infrared drying machine, the heat dissipation effect of the infrared heating lamp tube of the infrared drying machine is more uniform, the lamp box assembly can be conveniently overhauled, and therefore long-term stable drying work is guaranteed.

[0002] The current infrared dryer mainly includes a fixed machine base and a sliding machine base. A light box assembly is installed on the fixed machine base, and a material barrel is installed on the sliding machine base. The light box assembly is inserted in the material barrel for cleaning the inside of the barrel Infrared heating, the barrel is driven by a motor to rotate, one end of the barrel is provided with a feeding device, the other end of the barrel is provided with a discharge port, and the barrel is equipped with a spiral blade, while the current infrared dryer, the light box is fixed on the machine The frame cannot be moved, and the barrel is moved through the moving frame. Although the infrared dryer can achieve continuous drying of fruits and vegetables, there are still some disadvantages: 1. When the current infrared dryer needs maintenance, especially for the lamp tube. During the replacement operation, it is necessary to remove the material cylinder through the mobile frame, so that the lamp tube is exposed from the inside of the material cylinder, and the weight of the material cylinder is heavy, so it is relatively difficult to move; 2. The current light box needs to be cooled by air supply, and the current light box assembly The structure is unreasonable. The chamber inside the light box blows the lamp tube unevenly, resulting in uneven cooling of the lamp tube, which affects the service life. The temperature protection will cause the lamp to stop working, so that the drying efficiency of the infrared dryer will be reduced; 3. Since the dryer is continuous, the barrel needs to be rotated for a long time, and the current support ring outside the barrel is long-term. The temperature will rise during the rotation of time, and certain deformation will occur if the temperature is too high, which will eventually affect the smoothness of the rotation of the barrel; 4. The current drive of the barrel is driven by a motor and a connecting rod transmission mechanism, and the power of the motor There will be a certain transmission loss when it is transmitted to another support roller through the connecting rod, which will cause the rotation speed of the upstream support roller or the downstream support roller to be inconsistent, so that the loss of power is relatively large
