Embodiment 1

[0025] Embodiment 1: as Figure 1-2 As shown, the uniform flow hot air material drying method is to set up 6 rows in total on the two opposite side walls of the working chamber of the drying device for storing the materials to be dried, with two rows up and down, 3 rows in each row, and a distance of 600mm between the upper and lower sides and the left and right sides. A tuyere with a diameter of 200mm (evenly set along the height and depth direction of the two side walls of the working compartment of the drying box), so that each tuyere is connected with the heating compartment of the drying device through the air duct, and the hot air is passed along the side wall of the working compartment. The tuyere is sent into the working chamber in the drying box in a circumferential direction, so that the hot air sent in flows laterally along the inner side of the side wall, and then naturally diffuses to the entire working chamber. The surface of the material to be baked in the bakin...

Embodiment 2

[0029] Embodiment 2: as Figure 1-2 As shown, the uniform flow hot air material drying method is to set up 8 rows in total on the two opposite side walls of the working chamber of the drying device for storing the materials to be dried, with 4 rows in each row, and a distance of 500mm between the upper and lower sides and the left and right sides. A tuyere with a diameter of 150mm (evenly set along the height and depth direction of the two side walls of the working compartment of the drying box), so that each tuyere is connected with the heating compartment of the drying device through the air duct, and the hot air is passed along the side wall of the working compartment. The tuyere is sent into the working chamber in the drying box in a circumferential direction, so that the hot air sent in flows laterally along the inner side of the side wall, and then naturally diffuses to the entire working chamber. The surface of the material to be baked in the baking tray on the material...

Embodiment 3

[0033] Embodiment 3: as Figure 1-2 As shown, the uniform flow hot air material drying method is to set up 12 in total on the two opposite side walls of the working chamber of the drying device for storing the materials to be dried in three rows up and down, 4 in each row, and a distance of 500mm between the upper and lower sides and the left and right sides. The tuyere with a diameter of 120mm (evenly set along the height and depth direction of the two side walls of the working compartment of the drying box) connects each tuyere with the heating compartment of the drying device through the air duct, and sends the hot air along the tuyere on the side wall of the working compartment. Circumferentially sent into the working compartment of the drying box, so that the hot air sent in flows laterally along the inner side of the side wall, and then naturally diffuses to the entire working compartment. The surface of the to-be-baked material in the baking tray on the material shelf i...

Abstract

The invention provides a uniform-flow hot air material drying method, and belongs to the technical field of agricultural product processing. Hot air is fed into a working bin in the peripheral directions of multiple air ports on the side wall of the working bin of a drying device; the fed hot air laterally flows along the inner wall of the working bin to naturally disperse in the whole working bin; the hot air transversely and uniformly flows through materials in the bin in a dispersed state; the hot air is carried to exhaust from the air ports on the other side wall of the working bin after heat exchange with the materials; then, the air is reversely fed to repeat the process; and forward and reverse air feeding baking processes are repeatedly circulated to discharge moisture from a top moisture discharge port; fresh air enters a heating bin from a fresh air port formed in an air way of the drying device; drying parameters are designed according to a process; and the materials in theworking bin are uniformly dried. A hot air valve for lateral exhaust along the periphery is adopted to realize lateral supply of the hot air. The uniform-flow hot air material drying method has the advantages of low hot air circulating temperature difference in the working bin, high heat supply heat efficiency, capability of realizing uniform drying of various agricultural products and fresh materials, low energy consumption, simple structure, convenience to operate and the like.

Description

technical field [0001] The invention relates to a drying box for fruits and vegetables, in particular to a method for drying uniform-flow hot-air materials, and belongs to the technical field of agricultural product processing. Background technique [0002] Drying (drying) processing is one of the important processes in the agricultural product production and processing industry. It directly affects the performance, shape, quality and energy consumption cost of the processing process; drying equipment is the key to the timely processing of agricultural fresh products. , So as to have an important guarantee for warehousing logistics and long-distance transaction conditions. Drying is a complex heat exchange process, which is not only affected by material properties and medium parameters, but also related to climate conditions and drying processes, and even involves chemical and biological processes. The requirements for drying different materials can be very complex, not onl...
