Abstract

The invention discloses a tunnel kiln with angle-adjustable circulating air. The tunnel kiln comprises a case with a baking passage and a circulating air system above the baking passage. The circulating air system comprises a centrifugal fan fixedly mounted on the case, a main air pipe communicated with the centrifugal fan and a plurality of air return pipes disposed on the main air pipe at intervals. The main air pipe is fixed on the case along the length direction of the baking passage. The air return pipes are vertical to the main air pipe and connected to the same in a way that each air return pipe can rotate around self-axis. The bottom pipe wall of each air return pipe is provided with screen holes distributed along the length direction of the air return pipe. The tunnel kiln has the advantages the main air pipe and the air return pipes are reasonably arranged, even and stable circulating air can form in the case, surface color of baking products can be well controlled, different convection strength can be selected according to different baking products, and high universality is achieved.

Description

technical field [0001] The invention relates to the field of food baking tunnel furnace equipment, in particular to a tunnel furnace with adjustable angle circulating air. Background technique [0002] An oven is a device that cooks food with hot air, generally in a closed or semi-closed structure. Those heated with hot air in an open form are called grills. The oven can also be used to refer to a device that uses hot gas for high temperature processing. Generally, an auxiliary circulating air is formed in the oven. Its function is to generate air convection in a certain area of ​​the tunnel furnace. The hot air circulation convection movement formed will help the baked product to have a more uniform color, which is important for improving the overall performance of the tunnel furnace. significance. [0003] However, the auxiliary circulating air return duct in the existing oven is square, the air outlet is vertically downward, and the angle cannot be adjusted, so there i...
