Dried fruit multi-stage drying equipment

Abstract

The invention discloses dried fruit multi-stage drying equipment. The dried fruit multi-stage drying equipment comprises a box body assembly, a conveying assembly, a wind-direction changing assembly, wind guide bins, a cooling heat-insulating plate and a control system; the box body assembly is a rectangular box body, wherein the inner portion of the box body assembly is a cavity, and the front and rear end surfaces are provided openings correspondingly; the conveying assembly is arranged at the middle position in the cavity of the box body assembly, and penetrates out of the front and rear end surfaces of the box body, the wind guide bins are oppositely arranged on the upper and lower end surfaces of the inner cavity of the box body, and the wind-direction changing assembly is horizontally arranged on the right side wall or the left side wall of the inner wall of the box body; and the wind-direction changing assembly comprises fan blades, heating pipes and a motor, the fan blades are driven by the motor to rotate, the heating pipes are arranged at the peripheries of the fan blades in a surrounding mode. Through the unique structure of the inner portion of a drying box, after air flow is heated through the heating pipes, the hot air flow is guided to be up-down convective flow in the vertical direction through the upper and lower wind guide bins, so that a hot wind circulation system is formed in the drying box, thus the temperature is more uniform and heat is fully utilized when the drying equipment operates, and therefore the purposes of energy saving and high efficiency are achieved.

Description

Technical field [0001] The invention relates to the technical field of dried fruit drying equipment, in particular to a dried fruit multi-stage drying equipment. Background technique [0002] Dry fruit drying is a necessary part of dried fruit storage. For a long time, dried fruit drying has been mainly dried by natural drying and fuel combustion drying devices. These two drying methods mainly have the following problems: [0003] Natural drying is affected by the weather, which can easily cause incomplete drying and deterioration of dried fruits, resulting in low drying efficiency, long time-consuming and waste of manpower; [0004] The fuel drying system mainly suffers from environmental pollution, inconvenient temperature control, high temperature easy to cause burns, and reduced dried fruit drying quality. [0005] Therefore, it is necessary to design and manufacture dried fruit drying equipment suitable for efficient drying and environmental protection and energy saving of dried ...
