Description

Technical Field

[0001] This utility model relates to the field of roasting machines, specifically a quiet and low-noise roasting machine. Background Technology

[0002] A roasting machine is a specialized piece of equipment used for roasting and drying various nuts, seeds, beans, and other roasted foods. It is widely used in the food processing industry. Its core structure includes a heating system, a rotating drum, a temperature control device, and a power transmission component. It provides a uniform heat source through electric, gas, or electromagnetic heating, and the drum rotates at a constant speed to ensure that the food is heated evenly.

[0003] For example, authorization announcement number CN214316955U relates to a novel roasting machine, including a roasting machine body, a drum installed in the inner cavity of the roasting machine body, a guide blade installed inside the drum, a control box installed on one side of the roasting machine body, a temperature controller installed on the control box, and also includes a metal temperature measuring tube, a K-type armored thermocouple, and a base. The base is fixed to one side of the front wall of the roasting machine body. When the roasted food is heated as the drum rotates, it continuously comes into contact with the metal temperature measuring tube, thereby transferring the temperature of the roasted food to the metal temperature measuring tube. The K-type armored thermocouple inside the inner cavity of the metal temperature measuring tube transmits the temperature to the temperature controller, thus enabling precise detection of the temperature of the roasted food inside the drum, ensuring that the roasted food reaches the predetermined temperature and achieves the expected roasting temperature, making it suitable for widespread application.

[0004] However, the existing roasting machines are all made of aluminum alloy, which cannot be soundproofed. This results in significant vibration and noise during operation, as well as noise during food roasting, which affects the working environment. Therefore, there is an urgent need in the market to develop a quiet, low-noise roasting machine to help people solve the existing problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a quiet, low-noise roasting machine, including a roasting machine housing 1. A ceramic fiber sound insulation layer 101 is fixedly disposed on the inner wall of the roasting machine housing 1. A circular opening 102 is provided at the upper middle part of one side end face of the roasting machine housing 1. A roasting drum 2 is rotatably disposed at the upper middle part of the interior of the roasting machine housing 1. A heating mechanism 108 is fixedly disposed inside the roasting machine housing 1 at the lower end of the roasting drum 2. An inlet / outlet pipe 201 is fixedly connected to the side of the roasting drum 2 adjacent to the circular opening 102. Raw materials are added into the roasting drum 2 through the inlet / outlet pipe 201. The raw materials are roasted by heating the roasting drum 2 as it rotates through the heating mechanism 108.

[0024] Please see Figure 2 , Figure 3 and Figure 4A support ring 3 is fitted around the middle of the outside of the feed pipe 201. A first rubber seat 103 is fixedly connected to one side of the lower end face inside the roasting machine housing 1. The front and rear ends of the upper end of the first rubber seat 103 are connected to the lower ends of the front and rear ends of the support ring 3 through a first damping shock absorber 303. A circular support cover 4 is connected to the side of the roasting roller 2 away from the circular opening 102. A second rubber seat 105 is fixedly connected to the other side of the lower end face inside the roasting machine housing 1. The front and rear ends of the upper end of the second rubber seat 105 are connected to the lower ends of the front and rear ends of the circular support cover 4 through a second damping shock absorber 403. One side of the feed pipe 201 extends out of the side end face of the roasting machine housing 1 through the circular opening 102. The inner side of the support ring 3 is rotatably connected to the outer wall of the feed pipe 201 through a first bearing 301. The lower ends of the front and rear sections of the support ring 3 are fixedly connected to a first rotating connector 302. The front and rear ends of the upper end of the first rubber seat 103 are fixedly connected to a first rotating connector 302. The first damping shock absorber 303 is connected to the first rotating connector 302 and the first rotating seat 104 at its upper and lower ends via rotating shafts. A connecting cylinder 202 is fixedly connected to the middle of the end face of the frying drum 2 away from the feed pipe 201. The connecting cylinder 202 is inserted into the circular support cover 4 and is rotatably connected between the circular support covers 4 via a second bearing 401. The lower ends of the front and rear ends of the circular support cover 4 are fixedly connected to the second rotating connector 402. The front and rear ends of the upper end of the second rubber seat 105 are fixedly connected to the second rotating seat 106. The upper and lower ends of the second damping shock absorber 403 are connected to the second rotating connector 402 and the second rotating seat 106 via rotating shafts. The support ring 3 and the circular support cover 4 support both sides of the frying drum 2, and the first damping shock absorber 303 and the second damping shock absorber 403 buffer the mechanical vibration of the frying drum 2 during operation. The ceramic fiber sound insulation layer 101 reduces vibration noise.

[0025] Please see Figure 2 A drive device 5 is fixedly connected to the middle of the end face of the circular support cover 4 away from the frying drum 2. A drive motor 501 is fixedly installed inside the drive device 5. A rotating shaft 203 is fixedly connected to the middle of the outer side of the connecting cylinder 202. The rotating shaft 203 passes through the middle of the circular support cover 4 and extends into the drive device 5 and is fixedly connected to the output shaft of the drive motor 501. The frying drum 2 is driven to rotate by the drive motor 501.

[0026] Please see Figure 1 and Figure 2C-shaped cross-section guide rails 107 are fixedly connected to one end face of the roasting machine housing 1 and to both the upper and lower ends of the circular opening 102. A soundproof cover 6 is connected between the two C-shaped cross-section guide rails 107. A sound-absorbing layer 601 is provided on the inner wall of the soundproof cover 6. Limiting strips 602 are fixedly connected to both the upper and lower ends of the soundproof cover 6. The two limiting strips 602 are respectively inserted into the two C-shaped cross-section guide rails 107. When the roasting drum 2 is working, the soundproof cover 6 covers the opening of the inlet and outlet pipe 201 extending out of the roasting machine housing 1, thereby reducing the noise of food roasting. By pulling the soundproof cover 6 forward to move out of the inlet and outlet pipe 201, the feeding and discharging operation can be carried out. At the same time, a notch is provided at the rear end of the soundproof cover 6 for the inlet and outlet pipe 201 to move out, so as to prevent the inlet and outlet pipe 201 from obstructing the movement of the soundproof cover 6.

[0027] Working Principle: In use, first slide the soundproof cover 6 forward along the C-shaped guide rail 107 to expose the opening of the inlet / outlet pipe 201. Add the raw materials to be roasted into the roasting drum 2 through the inlet / outlet pipe 201. After adding the materials, reset the soundproof cover 6. The sound-absorbing layer 601 on its inner wall effectively blocks the noise from food collisions during roasting. Start the drive motor 501 to rotate the rotating shaft 203, which in turn drives the roasting drum 2 to rotate smoothly through the first bearing 301 and the second bearing 401. Simultaneously, the heating mechanism 108 heats the drum evenly. The mechanical vibrations generated during roasting are transmitted to the rubber seat for buffering and absorption through the first damping shock absorber 303 and the second damping shock absorber 403. This, combined with the ceramic fiber sound insulation layer 101 on the inner wall of the roasting machine housing 1, forms a double noise reduction structure, significantly reducing vibration noise during equipment operation. After roasting, slide the soundproof cover 6 open again to discharge the materials through the inlet / outlet pipe 201, achieving low-noise and high-efficiency roasting operation.
