Description

An electric drying oven

Technical Field

The utility model relates to the technical field of wine processing equipment, in particular to an electric heating drying box.

Background Art

When the existing drying box for wine processing raw materials is in use, the raw materials are directly placed on the placement plate, and then hot air is blown into the drying box to dry the raw materials. The hot air is blown in from a fixed position in the drying box, so that the raw materials on different placement plates are heated unevenly and the raw materials are dried unevenly; and when the existing drying box for wine processing raw materials is in use, the water vapor generated by drying is stored in the drying box, which increases the humidity inside the drying box and makes it difficult to fully dry the raw materials; at the same time, the existing drying box for wine processing raw materials directly discharges the hot air inside the drying box after drying. When drying again, the inside of the drying box needs to be heated again, and the hot air cannot be recycled, resulting in a waste of heat energy. Therefore, the research and development of new drying boxes for wine processing raw materials has received more and more attention from researchers.

In view of this, the utility model with the publication number CN214199444U proposes a drying box for wine processing raw materials, including a drying box body, a drying plate evenly installed at one end of the drying box body, and an air storage box installed at one end of the drying box body away from the drying plate, an electric heating plate installed at one end of the air storage box away from the drying box body, and a solenoid valve installed at the bottom of the air storage box, and a connecting pipe extending to the inside of the drying box body is installed at the output end of the solenoid valve. The utility model is equipped with a drying tube, a drying plate and a shunt pipe, and a screen is evenly arranged inside the drying plate. The hot air is shunted to the inside of the drying tube through the shunt pipe and blown out evenly through the aeration holes on the drying tube. The hot air can not only be blown directly above the raw materials, but also blown to the bottom of the raw materials through the drying air holes. The setting of multiple groups of drying tubes allows the raw materials on different drying plates to be heated evenly, so that the raw materials can be dried evenly, improving the drying effect.

However, the above-mentioned prior art still has shortcomings when used: 1. The materials on the drying plate have a certain thickness and are in a static state. It is difficult for the hot air to fully pass through the materials during ventilation drying, resulting in slow evaporation of moisture in the materials and uneven evaporation, thereby reducing the uniformity of drying; 2. In order to achieve the energy-saving heating and drying function, the prior art uses an air storage box to collect the hot air in the drying box, but the collected air is usually hot air with weakened thermal radiation, so there is a defect of low thermal energy storage capacity, and the energy-saving effect is poor.

To this end, the utility model provides an electric heating drying box.

Utility Model Content

In view of the deficiencies in the prior art, the purpose of the utility model is to provide an electric heating drying oven to solve the problems raised in the above background technology. The utility model has the function of drying, heating and stirring materials, which greatly improves the uniformity and efficiency of drying.

In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an electric drying oven, comprising a box body and a drying tray, a rotating shaft is arranged in the box body, an axially arranged bracket for lifting the drying tray is arranged on the rotating shaft, a hot air pipe close to one side is arranged in the box body, a horizontal pipe located below the bracket is fixedly connected to one side of the hot air pipe, an outer peripheral wall of the horizontal pipe is provided with evenly distributed air outlet holes, a horizontal bar located above the drying tray is fixedly connected to the outer peripheral wall of the hot air pipe, and a row of stirring rods extending into the drying tray are arranged at the bottom of the horizontal bar.

Furthermore, a U-shaped clearance notch used in conjunction with the rotating shaft is provided on one side of the drying and placing plate, and the stirring rod is a soft rubber stick.

Furthermore, the bracket is a cross-shaped bracket and a limiting rod bent upward is provided at a free end thereof.

Furthermore, a driving motor is fixedly arranged on the top of the box body, and an output shaft of the driving motor is fixedly connected to the top of the rotating shaft.

Furthermore, a heating box is connected to one side outside the box through a brake tube, and a circulating air pump and a drying chamber are arranged on the top of the box. The circulating air pump and the drying chamber are connected in series and communicated with the heating box and one end of the hot air pipe through a pipeline.

Furthermore, a guide sleeve is fixedly connected to one side of the gate tube, a gate plate is slidably connected to the guide sleeve, and a cylinder is fixedly connected to the outer side of the gate tube, and an output shaft of the cylinder is fixedly connected to one end of the gate plate.

Furthermore, an electric heating plate and a heat dissipation plate are arranged in the heating box.

The beneficial effects of the utility model are as follows:

1. The utility model sets a rotating shaft in the box body, the rotating shaft drives the drying plate to rotate, and a hot air pipe is set in the box body. The hot air pipe is provided with a horizontal pipe located below the drying plate, and a stirring rod is located above the drying plate, so that the material in the drying plate is evenly ventilated and produces a stirring effect.
