Abstract
Description
Technical Field
[0001] This utility model belongs to the field of food processing technology, and specifically relates to a roasting machine with a screening device. Background Technology
[0002] In the processing of roasted nuts, beans, and other roasted food products, the roasted products often become brittle and fragile due to high-temperature dehydration, resulting in broken nuts and fragments during subsequent transportation or packaging. To improve the product's appearance integrity and quality, existing technologies typically use sieves to sieve the roasted products a second time. Current technologies usually employ sieving equipment such as vibrating screens and drum screens to grade the roasted products, separating whole particles from fragments through sieves with matching apertures, thereby reducing the product's breakage rate and improving appearance integrity and quality stability.
[0003] 1. In the existing technology, the roasting and sieving processes are treated as independent steps, and sieving cannot be performed when the roasting is completed and the product is discharged, resulting in low processing efficiency. Therefore, the inventor has proposed a roasting machine with a sieving device.
[0004] 2. When the product is discharged from a horizontal drum-type roasting machine, it is guided by a spiral guide plate. However, when the rotation speed of the guide plate is relatively fast, the product is easily driven to rise along the drum and fall downwards along the middle and above the discharge port. This can easily cause the roasted product to splash and make collection inconvenient. Summary of the Invention
[0005] The technical problem to be solved by this utility model is that the screening process requires additional equipment to screen the roasted product, and screening cannot be carried out when the product is discharged after roasting. In view of the shortcomings of the prior art, a roasting machine with a screening device is provided.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] The device includes a machine body, inside which a roasting assembly is rotatably mounted, and the discharge port of the roasting assembly is equipped with a screening device; the screening device includes a diversion box, on which a screen plate is mounted, the screen plate being arranged in an arc shape from the bottom of the discharge port along the discharge rotation direction of the roasting assembly at the discharge port of the roasting assembly, and the interior of the diversion box is equipped with a movable screen plate.
[0008] Furthermore, a pusher is provided on one side of the movable sieve plate, and the pusher is slidably connected to the sieve holes of the sieve plate.
[0009] Furthermore, a spring platform is fixedly installed on one side of the movable sieve plate, and a spring is provided on the spring platform. One end of the spring is fixedly installed to the inner wall of the diversion box, and a handle is provided at one end of the movable sieve plate that extends through the top of the diversion box.
[0010] Furthermore, a roller is fixedly installed inside the diversion box, and a bushing is rotatably provided on the surface of the roller, with the movable screen plate slidably connected to the surface of the bushing.
[0011] Furthermore, a baffle plate is provided on one side of the diversion box.
[0012] Furthermore, the roasting assembly includes a roasting drum, one end of which is provided with a motor for driving the roasting drum to rotate.
[0013] Furthermore, the interior of the roasting cylinder is provided with a roasting plate and a guide plate, with the guide plate located at the outlet of the roasting cylinder.
[0014] Furthermore, the interior of the machine body is provided with a combustion chamber, and a stove is provided inside the combustion chamber.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. The material falls into the diversion box through the discharge port. The screen plate and the movable screen plate perform preliminary separation of the debris. The debris and small particles enter the diversion box through the screen holes. By directly integrating the screening device into the discharge port of the roasting component, the screening process is completed simultaneously when the material is discharged after roasting. There is no need for an additional collection and screening process, which effectively shortens the processing flow and improves production efficiency.
[0017] 2. By extending the sieve plate in an arc shape along the discharge direction of the roasting component and matching the spiral flow guide design of the guide plate, the length of the arc sieve plate matches the discharge speed of the roasting cylinder, so that the material is evenly spread on the surface of the sieve plate. The sieve plate involved along the splash trajectory can avoid the product splashing after roasting, and it is more convenient to collect the roasted product.
[0018] 3. When the roasted product gets stuck on the sieve plate and the movable sieve plate, pull the handle up and down to make the movable sieve plate slide along the roller, change the gap between it and the fixed sieve plate, and let the product stuck on the sieve plate and the movable sieve plate fall off. At the same time, the side-sloping pusher guides the direction of pushing, making it easier for the product to get out of the mesh formed by the sieve plate and the movable sieve plate, making it easier to clean the blockage in time and avoid frequent shutdowns for cleaning.

[0028] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0029] Example 1: See Figure 1-7 This embodiment of a roasting machine with a screening device includes a machine body 10, which is a stainless steel shell. A roasting component 20 is rotatably arranged in the hollow area inside the machine body 10, and a screening device 30 is provided at the discharge port of the roasting component 20.
[0030] The screening device 30 includes a diversion box 31, a crushing port 39 is provided on one side of the diversion box 31, a screen plate 32 is provided on the diversion box 31, the screen plate 32 is arc-shaped and covers the discharge port of the roasting component 20 along the discharge rotation direction of the roasting component 20, and a movable screen plate 33 is provided inside the diversion box 31.
[0031] The diversion box 31 is an inverted trapezoidal box with its bottom sloping towards the edge of the machine body 10, and its top is installed with the machine body 10 through bolt holes. The sieve plate 32 is a 304 stainless steel perforated plate with a thickness of 0.8mm and square holes with a side length of 3-8mm.
[0032] See Figure 4-5 A pusher 34 is provided on one side of the movable sieve plate 33. The pusher 34 is slidably connected to the sieve holes of the sieve plate 32 one-to-one. The pusher 34 is trapezoidal. When the movable sieve plate 33 is pushed up and down by the handle 37, the wedge-shaped rack of the pusher 34 is inserted into the sieve hole of the sieve plate 32. The inclined surface of the rack pushes the blockage debris upward, realizing the self-unblocking of the sieve hole. Driven by the movable sieve plate 33, the pusher 34 moves within the sieve hole of the sieve plate 32.
[0033] See Figure 6 A spring platform 35 is fixedly installed on one side of the movable sieve plate 33. A spring 36 is provided on the spring platform 35. One end of the spring 36 is fixedly installed to the inner wall of the diversion box 31. A handle 37 is provided at the top of the end of the movable sieve plate 33 that extends through the diversion box 31. In its natural state, the spring makes the pusher 34 located in the middle of the sieve hole of the sieve plate 32.
[0034] See Figure 6 A roller 40 is fixedly installed inside the diversion box 31. A bushing 41 is rotatably provided on the surface of the roller 40. The movable screen plate 33 is slidably connected to the surface of the bushing 41. The roller 40 is arranged in parallel, and both ends are fixedly connected to the inner wall of the diversion box 31. The bottom of the movable screen plate 33 is in contact with the outer wall of the bushing 41.
[0035] See Figure 7 A baffle plate 38 is provided on one side of the diversion box 31. The baffle plate 38 is a 304 stainless steel bent plate, which is installed at an angle at the outer outlet of the diversion box 31. The direction is consistent with the flow trajectory of the product, so that the product flows in a specific direction.
[0036] See Figure 1 - The roasting assembly 20 includes a roasting cylinder 21. The roasting cylinder 21 of the roasting assembly 20 is horizontally mounted on the center of the machine body 10 through a bearing seat. A motor 22 for driving the roasting cylinder 21 to rotate is provided at one end of the roasting cylinder 21. The radius of curvature of the sieve plate 32 is the same as the outer diameter of the roasting cylinder 21. The motor 22 is a variable frequency speed control motor, which is connected to another pulley at the end of the roasting cylinder 21 through a pulley, driving the roasting cylinder 21 to rotate at an adjustable speed.
[0037] See Figure 1 - The inside of the roasting cylinder 21 is provided with a roasting plate 23 and a guide plate 24. The guide plate 24 is located at the outlet of the roasting cylinder 21. The spiral roasting plate 23 is inclined and drives the product to turn over when the roasting cylinder 21 rotates. Beneficial effects
[0038] 1. The motor 22 drives the roasting drum 21 to rotate, and the internal roasting plate 23 stirs the material evenly. After the stir-frying is completed, the motor 22 is driven in the opposite direction to make the roasting drum rotate in the opposite direction. Under the guidance of the guide plate 24, the material moves towards the discharge port. The material falls into the diversion box 31 through the discharge port. The screen plate 32 and the movable screen plate 33 perform preliminary separation of the debris. The intact particles slide down the arc-shaped screen plate 32 to the collection area. The debris and small particles enter the diversion box 31 through the screen holes. By directly integrating the screening device 30 into the discharge port of the roasting component 20, the screening process is completed simultaneously when the material is discharged after roasting. There is no need for an additional collection and screening process, which effectively shortens the processing flow and improves production efficiency.
[0039] 2. By extending the sieve plate 32 in an arc shape along the discharge direction of the roasting component 20 and matching the spiral guide design of the guide plate 24, the length of the arc sieve plate 32 matches the discharge speed of the roasting cylinder 21, so that the material is evenly spread on the surface of the sieve plate. The sieve plate 32 involved along the splash trajectory can avoid the product splashing after roasting, and it is more convenient to collect the product after roasting.
[0040] 3. When the roasted product gets stuck on the sieve plate 32 and the movable sieve plate 33, pull the handle 37 up and down to make the movable sieve plate 33 slide along the roller 40, change the gap between it and the fixed sieve plate 32, and let the product stuck on the sieve plate 32 and the movable sieve plate 33 fall off. At the same time, the side-inclined pusher 34 guides the direction of pushing, making it easier for the product to get out of the mesh formed by the sieve plate 32 and the movable sieve plate 33, making it easier to clean the blockage in time and avoid frequent shutdowns for cleaning.
[0041] Example 2: Example 2 is a further improvement based on Example 1. See [link / reference] Figure 3 In this embodiment, a roasting machine with a sieving device is provided. The machine body 10 has a combustion chamber inside, and a stove 11 is provided inside the combustion chamber. The stove 11 extends out of the machine body 10 and is connected to gas. The gas combustion provides a heat source for the roasting drum 21.
