Abstract
Description
Technical Field
[0001] This invention belongs to the field of dehydrated vegetable processing technology, and particularly relates to a built-in heat-conducting dehydrated vegetable processing device and its dehydration method. Background Technology
[0002] Dehydrated vegetables, also known as rehydrated vegetables, are dried vegetables made by washing and drying fresh vegetables to remove most of their water content. The original color and nutritional components of the vegetables remain largely unchanged, making them easy to store and transport, and effectively regulating seasonal production. They can be rehydrated simply by soaking in water, retaining their original color, nutrients, and flavor. Current vegetable dehydration and drying methods often involve piling vegetables in a drying chamber and then introducing hot air to dry them. However, this method often results in uneven drying within the piled vegetables, leading to long drying cycles and poor drying results. Furthermore, the piled-up method prevents the removal of some moisture, which can become trapped inside the vegetables, increasing the risk of mold and spoilage. Therefore, it is necessary to upgrade the existing structure to improve dehydration efficiency and improve the vegetable discharge method. Summary of the Invention
[0003] To address the shortcomings of the prior art, the present invention solves the following problem: when vegetables are piled up in the drying chamber, the interior of the piled vegetables cannot be dried sufficiently and evenly, resulting in a long drying cycle and poor drying effect. At the same time, when the vegetables are discharged, the piled-up discharge method prevents some of the moisture carried by the vegetables from being fully discharged. As the vegetables pile up, moisture is buried inside the vegetables, which increases the risk of mold and spoilage later.

[0005] Furthermore, the air intake assembly includes an air intake pipe, an induced draft fan, a heating box, and an upper ventilator; the heating box is installed on the upper side of the built-in plate; the upper end of the heating box is connected to the air intake pipe; the induced draft fan is installed on the air intake pipe; the upper ventilator is fixedly installed in the middle of the upper end of the built-in plate; the ventilation shaft pipe passes through the center of the upper ventilator and is rotatably and sealingly connected to the upper ventilator; one side of the heating box is connected to the upper ventilator through a first connecting pipe, and a first opening and closing valve is provided on the first connecting pipe.
[0006] Furthermore, the air intake assembly also includes an extension pipe, a lower vent hood, and a lower guide pipe; a drive box is provided below the processing chamber; the extension pipe is installed inside one side of the processing chamber, and the upper end of the extension pipe is connected to the heating box through a second connecting pipe, which is provided with a second opening and closing valve; the lower vent hood is fixedly installed inside the drive box, and a lower guide pipe is rotatably installed on the upper end of the lower vent hood; the upper end of the lower guide pipe is connected to the rotating cover; the lower end of the extension pipe extends into the drive box and is connected to the lower vent hood.
[0007] Furthermore, the upper part of the ventilation shaft tube is evenly provided with ventilation holes around its perimeter, and the ventilation holes are distributed inside the upper ventilation hood.
[0008] Furthermore, a driven block is sleeved on the lower conductive tube; the bottom motor is installed in the drive box, and a power wheel is provided on the lower side of the bottom motor; the power wheel and the driven block are engaged by a sprocket.
[0009] Furthermore, the opening and closing discharge port is equipped with a lifting baffle; the upper side of the lifting baffle is equipped with an opening and closing telescopic device; the opening and closing telescopic device controls the up and down movement of the lifting baffle.
[0010] Furthermore, an exhaust opening is provided on one side of the upper end of the processing chamber.
[0011] Furthermore, a vegetable entry cover is provided on one side of the processing chamber; the lower end of the vegetable entry cover extends through the underside of the built-in plate.
[0012] Furthermore, baffles are provided on the outer side of the opening and closing discharge port.
[0013] A dehydration method for a built-in heat-conducting dehydration vegetable processing device includes the following steps: The vegetables to be dried are fed into the processing chamber. Then, an induced draft fan is turned on, and airflow is discharged through the heating chamber, the first connecting pipe, the upper vent hood, the vent shaft pipe, and the side branch pipe. Simultaneously, a rotating motor drives the vent shaft pipe and the side branch pipe to rotate, thus drying the vegetables from the inside. After drying, the first connecting pipe is closed, and the second connecting pipe is opened. Airflow is discharged through the heating chamber, the second connecting pipe, the extension pipe, the lower vent hood, the lower guide pipe, the rotating hood, and the airflow impact pipe. Simultaneously, a bottom motor drives the lower vent hood and the lower guide pipe to rotate. By opening multiple openable and closed discharge ports, and through the synchronous rotation and impact of multiple lower guide pipes, the vegetables are evenly dispersed and discharged from the multiple openable and closed discharge ports, preventing vegetable accumulation and water vapor buildup.
[0014] The beneficial effects of this invention are as follows: 1.

At the same time, a rotating motor drives the ventilation shaft pipe and the side branch pipe to rotate. In this way, hot air is ventilated from inside the vegetables. The rotation and agitation of the side branch pipes make the airflow discharge smooth, and the drying and heating are more uniform and dispersed, resulting in a better dehydration effect.
[0015] 2. This invention enables the dispersed discharge of vegetables. By adjusting the path of the hot airflow, closing the first connecting pipe and opening the second connecting pipe, the hot airflow is discharged through the heating box, the second connecting pipe, the extension pipe, the lower ventilation hood, the lower guide pipe, the rotating hood, and the airflow impact pipe. Simultaneously, the bottom motor drives the lower ventilation hood and the lower guide pipe to rotate. By opening multiple openable and closed discharge ports, the vegetables are evenly dispersed and discharged from the multiple openable and closed discharge ports through the synchronous rotation and impact of multiple lower guide pipes. In this way, the impact of the hot airflow disperses and discharges the vegetables while also removing residual moisture, preventing moisture from being buried in the vegetables during discharge.
[0016] 3. This invention enables the regulation, distribution, and zoned utilization of a single air source. By opening the first connecting pipe and closing the second connecting pipe, the airflow passes through the heating box, the first connecting pipe, the upper vent hood, the vent shaft pipe, and the side branch pipe, achieving drying and dehydration. By closing the first connecting pipe and opening the second connecting pipe, the hot airflow path is regulated. By closing the first connecting pipe and opening the second connecting pipe, the hot airflow passes through the heating box, the second connecting pipe, the extension pipe, the lower vent hood, the lower guide pipe, the rotating hood, and the airflow impact pipe, achieving dispersed discharge, making it flexible and convenient to use.
