Abstract

The invention relates to a jujube drying device and a drying method. The jujube drying device comprises a three-stage air duct and a drying box. Hot air of the three-stage air duct is divided into 60-70 DEG C, 40-50 DEG C and 25-35 DEG C. A rotary bracket is arranged in the drying box. The hot air enters the drying box through the air duct, the rotary bracket rotates, it is avoided that thin skin of jujubes ruptures due to the long-time blow-drying, and the drying moisture is drained out of the drying box through a condenser. By the adoption of the jujube drying device and the drying method, the problems that the jujubes are difficult to air-dry, the drying is non-uniform, and the jujubes are likely to be damaged are solved, the drying efficiency of the jujubes is improved, the quality of materials is guaranteed, and meanwhile the energy consumption is saved.

Description

technical field [0001] The invention relates to a device and a drying method for drying red dates, belonging to the technical field of food processing. Background technique [0002] Fresh dates are dehydrated and dried to obtain red dates, which are easy to digest and store. Jujubes for storage should be moderately dry, free from damage, pests and diseases, ruddy in color, and neat in size. [0003] At present, the dehydration and drying of jujube mainly adopts a drying room. The drying room is a brick-concrete structure. The top is provided with moisture-discharging ventilation holes, the bottom is provided with a fire pit, the front part is provided with a door, and the rear part is provided with a chimney and a furnace. This kind of drying room covers a large area and uses coal-fired heat for heating. The dried red dates have a high peeling rate, high energy consumption and pollute the environment. Contents of the invention [0004] Aiming at the disadvantages of the ...
