Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and more specifically, to a potato chip drying device. Background Technology

[0002] As a common food ingredient or snack, drying is an important step in the processing of potato chips. Traditional potato chip drying methods often have some problems. For example, some small workshops may use natural sun-drying, which is greatly affected by the weather, takes a long time to dry, and is easily contaminated by dust, insects, etc., and cannot guarantee the quality and hygiene standards of potato chips.

[0003] Some rudimentary drying equipment may only have a simple heating chamber. During the drying process, the potato slices are not turned evenly, resulting in low drying efficiency. The parts near the heating source may be over-dried, while the parts far from the heating source may be under-dried. At the same time, traditional drying equipment is not efficient in heat utilization, resulting in serious energy waste and increasing production costs. Therefore, those skilled in the art have provided a potato slice drying device to solve the above-mentioned problems. Utility Model Content

A drive motor is fixedly installed on the top of the drying chamber, and the output shaft of the drive motor passes through the drying chamber and is fixedly installed on the top of the drying rack. An installation groove is provided inside the drying chamber, and a partition is fixedly connected to the inner wall of the installation groove. An electric heating wire is fixedly installed on the back of the partition. An air pipe is fixedly installed on the inner wall of the installation groove, and the top end of the air pipe passes through the installation groove and extends into the interior of the drying chamber.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figures 1-4 In this utility model, a potato chip drying device includes a drying box 1. A drying rack 2 is rotatably connected to the inner bottom wall of the drying box 1. Storage trays 3 arranged at equal intervals are detachably connected to the drying rack 2. A drive motor 4 is fixedly installed on the top of the drying box 1. The output shaft of the drive motor 4 passes through the drying box 1 and is fixedly installed on the top of the drying rack 2. An installation groove 5 is provided inside the drying box 1. A partition 6 is fixedly connected to the inner wall of the installation groove 5. An electric heating wire 7 is fixedly installed on the back of the partition 6. An air pipe 8 is fixedly installed on the inner wall of the installation groove 5. The top end of pipe 8 passes through the mounting groove 5 and extends into the interior of the drying chamber 1. Two diversion boxes 9 are fixedly installed on the top of the drying chamber 1. A pressure valve 10 is installed on the inner wall of the diversion box 9. The pressure valve 10 is connected to the interior of the drying chamber 1. Equally spaced return pipes 11 are fixedly connected to the inner wall of the diversion box 9. The other end of the return pipe 11 passes through the mounting groove 5 and extends to the outside of the drying chamber 1. An air pump 12 is fixedly installed on the inner wall of the mounting groove 5. The air pump 12 is located in front of the return pipe 11. The pipe of the air pump 12 passes through and extends to the outside of the drying chamber 1.

[0022] The portion of the return pipe 11 located inside the mounting groove 5 is bent. Evenly distributed heat sinks 15 are installed on the return pipe 11. The heat sinks 15 are located inside the mounting groove 5 and are made of metal.

[0023] The outer ring of the bearing 17 is mounted on the inner bottom wall of the drying oven 1.

[0024] When drying potato slices is required, the user opens the door of the drying chamber 1 to expose its interior. The user then places the storage basin 3 containing the potato slices into the drying rack 2. The user then closes the door to seal the interior of the drying chamber 1. The air pump 12 and heating wire 7 are then powered on. The heating wire 7 heats up, causing the surrounding airflow to rise. The air pump 12 then generates suction to draw external airflow into the mounting slot 5. The airflow passes through the partition 6 and then contacts the heating wire 7, further heating it. As more airflow enters, the heated airflow passes through the air pipe 8 into the interior of the drying chamber 1, causing the internal temperature of the drying chamber 1 to rise and dry the potato slices. The drive motor 4 drives the drying rack 2, which is fixedly connected to it, to rotate synchronously, thereby drying multiple sets of... The storage basin 3 rotates, increasing the contact area between the potato slices and the heat flow, thereby improving drying efficiency. At the same time, the pressure valve 10 automatically opens. When the airflow continuously enters the drying chamber 1, the internal pressure of the drying chamber 1 is relatively high. At this time, the pressure valve 10 opens to send the airflow into the distribution box 9. The incoming airflow contains some heat and enters the return pipe 11. Then, it enters the mounting slot 5 along the return pipe 11. With the help of multiple heat sinks 15, the heat is dissipated, so that the airflow sent into the mounting slot 5 by the air pump 12 will first contact the return pipe 11 to achieve preheating. Then, the airflow penetrates the partition 6 and is heated by the heating wire 7 before entering the drying chamber 1. When drying is completed, the equipment stops operating. After opening the chamber door, the multiple storage basins 3 can be taken out.

[0025] In this invention, the drive motor 4 drives the drying rack 2 to rotate, causing the potato slices in the storage basin 3 to continuously change position, increasing the contact area with the heat flow and thus improving drying efficiency. At the same time, when the pressure inside the drying chamber 1 is high, the hot airflow enters the mounting slot 5 through the return pipe 11, and the heat sink 15 is used to preheat the newly entered airflow, realizing the multiple use of heat and reducing energy waste. Moreover, the user only needs to simply put the storage basin 3 into the drying chamber 1, close the chamber door to start drying, and open the chamber door to take out the storage basin 3 after drying. The operation process is simple and convenient.

[0026] Please see Figure 1 and 4 The front of the drying oven 1 is detachably connected to two dust covers 13, and the pipe of the air pump 12 is located inside the dust cover 13.

[0027] In this invention, the dust cover 13 can filter the airflow drawn in by the air pump 12, preventing dust from entering the interior of the drying oven 1 and contaminating the potato slices.

[0028] Please see Figures 1-3 The drying oven 1 has a detachable protective cover 14 on both the left and right sides, and the return pipe 11 is located inside the protective cover 14.

[0029] In this invention, the protective cover 14 is installed on both sides of the drying oven 1, so that most of the multiple sets of return pipes 11 are located inside for protection, and the protective cover 14 is in a sealed state to prevent the return pipes 11 from exchanging heat with the outside air and causing heat loss.

[0030] Please see Figure 1 and 2 The bottom of the drying box 1 is provided with evenly distributed casters 16, which are installed at the bottom of the drying box 1.

[0031] In this invention, multiple casters 16 at the bottom of the drying box 1 support the drying box 1. The casters 16 can move the drying box 1, reducing the difficulties caused by movement and facilitating the subsequent processing of potato slices and the flexible use of the equipment.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
