Description

Technical Field

[0001] The utility model relates to the technical field of oil product processing, in particular to a rapeseed frying machine. Background Art

[0002] Rapeseed, the fruit of the cruciferous plant Brassica rapa, features long siliques, numerous pods, and plump seeds. The oil content in rapeseed ranges from 37.5% to 46.3%, with the oil content varying slightly depending on the type of rapeseed. Rapeseed, also known as Brassica rapa, is a herbaceous cruciferous crop and a major oilseed and nectar-producing crop in China. Its seeds are a primary raw material for making infused oils.

[0003] Chinese patent document CN220685035U discloses a drum rapeseed roasting machine. The machine features a rotating shaft at the motor output end. This shaft extends into the drum and is equipped with a second rotating shaft, both ends of which are rotatably connected to the drum interior. A stirring assembly is located outside the second rotating shaft, and a linkage assembly is located between the rotating shaft and a linkage rod. This machine stirs the rapeseed inside the drum while it is being rotated and roasted, with the stirring direction being opposite to the drum's rotation, thereby improving roasting efficiency and roasting uniformity. Furthermore, this operation is driven by a single motor, resulting in greater energy efficiency.

[0004] The existing technology has the following problems: The aforementioned seed roasters do not pre-treat the rapeseed before roasting, allowing particulate impurities in the rapeseed to mix into the drum, where they absorb oil, potentially reducing the oil yield of subsequent rapeseed oil extraction. Furthermore, these seed roasters utilize multiple stirring rods to roast the rapeseed, making discharge more complex and requiring no cooling, which increases subsequent rapeseed processing time.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, a rapeseed roasting machine includes a base 1, and seed roasting components 2 are fixedly installed on the left and right parts of the upper end of the base 1, a feed filter component 3 is fixedly installed on the right part of the top of the seed roasting component 2, and a feed air cooling component 4 is fixedly installed on the right part of the bottom of the seed roasting component 2.

[0027] The seed roasting assembly 2 tumbles and roasts the rapeseed in the heating furnace 22, conveying it to the left side of the furnace 22 during roasting. The feed filter assembly 3 pre-filters and screens the rapeseed entering the heating furnace 22, separating and collecting impurities. This prevents impurities from remaining during the roasting process and affecting the subsequent oil yield, thereby ensuring oil quantity and quality. The feed air cooling assembly 4 directs the rapeseed from the heating furnace 22 via a guide plate 42 onto a motorized conveyor belt 43, allowing the rapeseed to be air-cooled during the flattening process. Several air jets 49 rapidly cool the roasted rapeseed, inhibiting oxidation and minimizing the damage to nutrients caused by high temperatures.

[0028] like Figure 3 As shown, the seed frying assembly 2 includes two fixed plates 21, the lower ends of the two fixed plates 21 are fixedly installed on the left and right parts of the upper end of the base 1, and a cylindrical heating furnace 22 is fixedly installed on the opposite sides of the two fixed plates 21. The middle part of the right side of the heating furnace 22 is movably connected with a spiral frying mechanism 23 that passes through the right part of the heating furnace 22.

[0029] The heating furnace 22 is a conventional structure, comprising a cylindrical body equipped with heating elements such as electric heating tubes and gas burners for generating heat, which are not specifically defined herein. The spiral stir-frying mechanism 23 is a conventional mechanism comprising a motor, a connecting shaft, and a plurality of spiral auger blades. After the rapeseed is added to the heating furnace 22, the spiral auger blades rotate, pushing the rapeseed to the left and causing it to tumble and stir in the gaps between adjacent spiral auger blades, thereby stir-frying the rapeseed.

[0030] like Figure 3 and Figure 4 As shown, the feed filter assembly 3 includes a processing cover 31, the lower end of the processing cover 31 is fixedly installed at the right position of the top of the outer wall of the heating furnace 22, the processing cover 31 is connected to the heating furnace 22, and the middle part of the upper end of the processing cover 31 is connected and fixedly installed with a feed hopper 32, and a sealing cover 33 is inserted into the top of the inner wall of the feed hopper 32.

[0031] When the roasting machine is working, the cover 33 can be covered to reduce heat loss. The rapeseed is added into the heating furnace 22 by the feed hopper 32 and the processing cover 31.

[0032] like Figure 4 and Figure 5 As shown, the middle part of the inner wall of the feed hopper 32 is rotatably connected to a rotating shaft 34 that passes through the front part of the feed hopper 32, and the middle part of the outer wall of the rotating shaft 34 is fixedly installed with a number of blades 35 arranged in a ring form. The bottom position of the front and rear parts of the inner wall of the processing cover 31 is rotatably connected to a rotating rod 36 that passes through the front part of the processing cover 31, and the front part of the outer wall of the rotating shaft 34 is fixedly connected to a linkage mechanism 37, and the bottom of the linkage mechanism 37 is fixedly connected to the front part of the outer wall of the rotating rod 36.

[0033] During the process of adding rapeseed, the downward force of the rapeseed drives several blades 35 to flip, thereby causing the rotating shaft 34 to rotate. The linkage mechanism 37 is a common mechanism, which includes two pulleys and a belt. The two pulleys are fixedly connected to the front of the outer wall of the rotating shaft 34 and the rotating rod 36 respectively. When the rotating shaft 34 rotates, the belt drive can realize the synchronous rotation of the rotating shaft 34 and the rotating rod 36.

[0034] like Figure 4 and Figure 5 As shown, a cam 38 is fixedly sleeved on the middle part of the outer wall of the rotating rod 36, and a filter screen 39 is rotatably connected to the top position of the right part of the inner wall of the processing cover 31. The outer surface of the cam 38 abuts against the middle part of the lower end of the filter screen 39. A slag discharge groove is opened in the middle part of the outer wall of the processing cover 31, and the front and rear sides of the left part of the filter screen 39 are movably sleeved on the inner wall of the slag discharge groove. A mounting plate 310 is fixedly installed on the bottom left side of the processing cover 31, and springs 311 are fixedly installed on the front and rear parts of the upper end of the mounting plate 310. The upper ends of the two springs 311 are fixedly connected to the front and rear positions of the left part of the lower end of the filter screen 39.

[0035] When the rotating rod 36 rotates, the cam 38 intermittently lifts the filter screen 39, and the filter screen 39 cooperates with the two springs 311 to achieve vibration, thereby accelerating the screening effect. The filter screen 39 extends out of the slag trough, and impurities in the rapeseed fall into the collection box 313 due to the inclined filter screen 39.

[0036] like Figure 4 As shown, an open fixed box 312 is fixedly installed at the left position of the top of the outer wall of the heating furnace 22, and a movable groove is opened in the middle of the rear side of the fixed box 312. The inner wall of the movable groove is slidably connected to a collection box 313, and the collection box 313 is located below the filter 39.

[0037] When cleaning impurities later, the collecting box 313 can be slid out of the movable groove.

[0038] like Figure 5As shown, the feeding air cooling component 4 includes an openable and closable discharge pipe 41, the top of the discharge pipe 41 is fixedly installed at the left position of the bottom of the outer wall of the heating furnace 22, a guide plate 42 is fixedly installed at the right bottom of the left fixed plate 21, an electric conveyor belt 43 is fixedly installed at the middle of the upper end of the base 1, the guide plate 42 is located above the electric conveyor belt 43, and a through groove matching the electric conveyor belt 43 is opened at the left bottom of the right fixed plate 21.

[0039] During the frying process of rapeseed, it is pushed to the left by the spiral frying mechanism 23 and falls from the discharge pipe 41. The rapeseed passes through the guide plate 42 and falls evenly onto the outer peripheral surface of the electric conveyor belt 43. The electric conveyor belt 43 is an existing mechanism. Its left part is fixedly connected to the upper left part of the base 1, and its right part extends to the outside through the through slot. The rapeseed is transported to the appropriate position by its transmission.

[0040] like Figure 2 and Figure 6 As shown, an adjustment plate 44 is rotatably connected to the left bottom of the right fixed plate 21, and a micro-electric push rod 45 is rotatably connected to the upper left end of the adjustment plate 44. The end of the micro-electric push rod 45 away from the adjustment plate 44 is rotatably connected to the left bottom of the right fixed plate 21. A fan 46 is fixedly installed on the right bottom of the right fixed plate 21. The output end of the fan 46 passes through the right part of the right fixed plate 21 and is fixedly installed with a delivery pipe 47. The end of the delivery pipe 47 away from the fan 46 passes through the top of the adjustment plate 44 and is fixedly installed with a cooling pipe 48. The front and rear ends of the cooling pipe 48 are fixedly connected to the front and rear parts of the lower end of the adjustment plate 44. A number of linearly arranged nozzles 49 are fixedly installed on the left part of the outer wall of the cooling pipe 48.

[0041] Fan 46 is a conventional mechanism, its internal impeller rotating to draw in and discharge air. Delivery pipe 47 delivers the discharged air to cooling pipe 48, where it is then applied to the surface of the rapeseed by several nozzles 49, rapidly cooling the high-temperature rapeseed. The telescopic miniature electric push rod 45 adjusts the cooling angle of cooling pipe 48, providing high applicability. Delivery pipe 47 is a flexible hose.

[0042] The working principle of the present invention is as follows: rapeseed is added to the heating furnace 22 through the feed hopper 32 and the processing cover 31. During the process of adding rapeseed, its downward impact drives several blades 35 to flip, thereby causing the rotating shaft 34 to rotate accordingly. When the rotating shaft 34 rotates, it can drive the rotating rod 36 to rotate synchronously through the linkage mechanism 37, so that the cam 38 intermittently lifts the filter screen 39. The filter screen 39 cooperates with the two springs 311 to achieve vibration, thereby accelerating the screening effect. The filter screen 39 extends out of the slag trough, and impurities in the rapeseed fall into the collection box 313 due to the inclined filter screen 39. When cleaning the impurities subsequently, the collection box 313 can be slid out of the movable groove.

[0043] During the frying process of rapeseed, the spiral frying mechanism 23 pushes the rapeseed to the left and falls from the discharge pipe 41. The rapeseed passes through the guide plate 42 and evenly falls onto the outer peripheral surface of the electric conveyor belt 43. The rapeseed is transported to a suitable position by the conveying pipe 47. During the transmission of the rapeseed, the conveying pipe 47 conveys the airflow discharged by the fan 46 to the cooling pipe 48, and then a number of nozzles 49 act on the surface of the rapeseed to quickly cool down the high-temperature rapeseed.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
