Technical Field

[0001] The utility model relates to the field of tomato peel powder processing devices, in particular to a uniform drying device for tomato peel powder processing. Background Art

[0002] Tomato skin powder has a high lycopene content and is a safe and natural pigment and food flavor additive. At the same time, its raw materials are inexpensive and have great application prospects in the food processing industry. The processing of tomato skin powder involves a series of cleaning, sorting, thermal crushing, pulping, vacuum concentration and drying processes, among which drying is often an important post-process for the final formation of tomato skin powder products.

[0003] There are many ways to process and dry tomato skin powder. Most people now choose to heat and dry it while stirring it. However, there is often a lot of material in the processing and manufacturing of tomato skin powder. Heating and drying the tomato skin powder from only one direction is not only inefficient, but also very uneven in drying.

[0004] Therefore, in view of the above-mentioned situation that the amount of material is large during the processing of tomato peel powder, the traditional single-direction drying method is inefficient and the drying is uneven, a multi-directional heat conduction and hot air dual drying mode can be designed to further accelerate the uniform drying of tomato peel powder.

Five heating resistors 4 are arranged equidistantly in the longitudinal direction. The heating resistors 4 are of annular structure and are clamped and fixed in the buckle 3 on the same horizontal plane. The heating resistors 4 are externally connected to the mains power supply. A guide cover 6 is sleeved between the inclined plates at the upper ends of the outer insulation cover 2 and the inner insulation cover 5. The guide cover 6 is composed of three layers of annular plates: upper, middle and lower. The middle annular plate of the guide cover 6 is provided with 30-60 flow holes 7 in an annular shape for conveying hot air to the upper tomato skin powder. Eight guide pipes 8 extending to the bottom of the drying tank 1 are also installed on the middle annular plate of the guide cover 6 to convey hot air to the lower tomato skin powder. The air flow conveyed by the external blower enters the guide channel formed between the outer insulation cover 2 and the inner insulation cover 5, and is blown from top to bottom to the upper surface of the tomato skin powder through the guide cover 6, and the guide pipe 8 is blown from bottom to top to the bottom of the tomato skin powder, forming a two-way hot air drying mode.

[0025] See also Figure 4-5 In this embodiment, the guide pipe 8 is an L-shaped pipe with its lower end extending obliquely upward. The upper end of the guide pipe 8 is fixed in the mounting hole provided on the guide cover 6 by extrusion and insertion of a rubber plug. The guide pipe 8 is assembled and connected to the guide cover 6 through the rubber plug. The installation and disassembly are simple. A part of the hot air entering the guide cover 6 is transported downward along the guide pipe 8 and output upward again from the bottom of the tomato skin powder. A motor 13 is installed at the lower end of the inner heat preservation cover 5. A transmission roller 14 extending into the inner heat preservation cover 5 is installed at the upper end of the transmission shaft of the motor 13. The outer wall of the driving roller 14 is fixedly connected with a mixing frame 15.

The driving roller 14 is a hollow structure and has a built-in rod-shaped resistance wire connected to the mains. The driving roller 14 is a copper pipe. The upper end of the driving roller 14 is below the middle annular plate of the air guide cover 6.

[0026] See also Figure 6In this embodiment, a discharge port 9 is provided at the lower end of the drying tank 1, and an arc-shaped leakage port 10 is opened at the lower end of the inner heat-insulating cover 5, and the leakage port 10 is connected with the discharge port 9. After drying, the tomato skin powder is discharged from the drying tank 1 through the leakage port 10 and the discharge port 9. Four support frames 12 are welded and fixed around the lower edge of the leakage port 10. A cylinder is embedded in the support frame 12.

[0027] During operation, the user starts the cylinder to drive the sealing ring 11 to move upward, and the rubber strip seals the leakage port 10 tightly, and then puts the tomato peel powder into the drying tank 1 and drops it into the inner heat preservation cover 5;

[0028] Then the motor 13 is started to drive the transmission roller 14 and the mixing frame 15 to rotate, stirring the tomato peel powder. At the same time, the rod-shaped resistance wire inside the transmission roller 14 is energized to generate heat, which is radiated to the surroundings through the copper transmission roller 14 with high thermal conductivity, thereby assisting the drying of the tomato peel powder in the middle.

[0029] While the tomato skin powder is being stirred, an external blower outputs air flow into a guide channel formed between the outer heat-insulating cover 2 and the inner heat-insulating cover 5. The air flow passes through the heating resistor wire 4 to form hot air. A part of the air flow is transported from above to the upper surface of the tomato skin powder through the flow holes 7 on the guide cover 6, and the other part of the air flow is output upward again from the bottom of the tomato skin powder through the guide pipe 8.

[0030] Through the above steps, the guide channel formed between the outer insulation cover 2 and the inner insulation cover 5 is used in conjunction with the guide pipe 8 to simultaneously deliver hot air from the upper surface and the lower bottom of the tomato skin powder, which can not only assist in drying the material, but also utilize the thrust generated by the airflow to assist in turning the tomato skin powder at the bottom, thereby improving the drying efficiency and achieving very uniform bidirectional drying, thereby solving the problem of large material volume during tomato skin powder processing, low efficiency and uneven drying in the traditional single-direction drying method.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
