Description

Technical Field

[0001] This invention belongs to the field of production technology, and in particular relates to a drum-type fried rice machine. Background Technology

[0002] With the rapid development of pre-prepared meals and central kitchens, building efficient, fully automated continuous fried rice production lines has become an urgent need in the industry. An ideal continuous production line should achieve uninterrupted operation throughout the entire process, from washing rice, steaming rice, frying, quick-freezing to packaging, in order to improve efficiency, ensure consistent quality, and reduce labor costs.

[0003] Currently, rice washing, steaming, quick-freezing, and packaging processes have relatively mature continuous equipment capable of automated material flow and processing. However, existing fried rice equipment (drum-type fried rice machines) operates on an intermittent basis: a fixed quantity of rice and ingredients is fed into the frying chamber at once, and after frying, the machine must be stopped, the discharge port opened to empty the finished product, the machine shut down again, and materials re-fed before the next batch can be fried. This "fry one batch, stop once, clean once, re-feed" operation disrupts the continuity of the production line. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a drum-type fried rice machine that connects to the frying process.

[0005] The objective of this invention can be achieved through the following technical solution: a drum-type fried rice machine, comprising:

[0006] frame;

[0007] A roller, which is rotatably mounted on the frame, and has a receiving cavity with openings at both ends formed therein;

[0008] A stirring spatula, which is rotatably disposed within the receiving cavity;

[0009] The lifting unit includes a support leg and a lifting leg that are hinged to the frame. The height of the lifting leg is adjustable in the vertical direction. The support leg and the lifting leg are respectively located at both ends of the length direction of the roller.

[0010] A heating element is located below the drum.

[0011] In the aforementioned drum fried rice machine, abutment rings are fixedly provided at both ends of the outer surface of the drum. The abutment rings extend radially along the drum. Two sets of limiting parts are rotatably provided on the frame. Each set of limiting parts includes at least two limiting wheels rotatably provided on the frame. The two sets of abutment parts are provided at both ends of the drum and abut against the abutment rings. The axis of the limiting wheels is perpendicular to the axis of the drum.

[0012] In the aforementioned drum fried rice machine, a transmission rack is fixedly arranged radially on the outer surface of the drum, a drive unit is fixedly arranged on the frame, and a drive gear is driven at the output end of the drive unit to mesh with the transmission rack.

[0013] In the aforementioned drum fried rice machine, two mounting brackets are fixedly installed on the frame at the two ends of the drum, and a connecting shaft is rotatably connected between the two mounting brackets. The stirring shovel is fixedly installed on the connecting shaft.

[0014] In the aforementioned drum fried rice machine, a plurality of stirring shovels are arranged at intervals along the axial direction on the connecting shaft, and three adjacent stirring shovels are arranged in a ring-shaped interval in the circumferential direction.

[0015] In the aforementioned drum fried rice machine, the rotation direction of the connecting shaft is the same as the rotation direction of the drum, but their rotation speeds are different.

[0016] In the aforementioned drum fried rice machine, the heating unit includes multiple rows of infrared burners fixedly mounted on the frame for heating the drum.

[0017] In the aforementioned drum fried rice machine, a support platform is provided below the frame, and the support leg is hinged to the support platform. The support leg includes a connecting rod and an adjusting rod. The connecting rod is hinged to the support platform, and the adjusting rod is hinged to the frame. The total length of the adjusting rod and the connecting rod is adjustable.

[0018] In the aforementioned drum fried rice machine, a feeding inclined plate and a discharging inclined plate are fixedly installed at the two ends of the drum, respectively.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: under the action of gravity and stirring, the material slowly moves along the inner wall of the drum to the lower end (discharge end), and is automatically discharged from the discharge port after frying is completed. By controlling the feeding speed, stirring shovel speed and drum rotation speed, continuous frying operation of "feeding and discharging at the same time" can be realized.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0028] like Figures 1-5 As shown, this embodiment provides a drum fried rice machine, including a frame 100, a drum 200, a stirring spatula 202, a lifting unit and a heating unit 400.

[0029] The frame 100 is an integral support structure with good stability and high temperature resistance.

[0030] The interior of the drum 200 forms an axially extending cavity 201, and both ends of the drum 200 have openings. The drum 200 rotates around its axis, and the rotation speed is adjustable to meet the stir-frying needs of different ingredients.

[0031] The stirring spatula 202 is set inside the receiving cavity 201 of the drum 200, which can turn over, disperse and mix the internal materials while the drum 200 rotates, ensuring uniform heating and preventing clumping.

[0032] The lifting unit includes a support foot 300 and a lifting foot 301. The support foot 300 is fixedly hinged to the bottom of the frame 100 near the end of the roller 200, serving as a fulcrum for rotation; the lifting foot 301 is hinged to the bottom of the other end of the frame 100. By adjusting the height of the lifting foot 301 in the vertical direction, the roller 200 as a whole can be tilted around the end where the support foot 300 is located.

[0033] The heating element 400 is located directly below the roller 200 and is used to uniformly heat the bottom of the roller 200.

[0034] In use, the lifting unit adjusts the drum 200 to the desired angle. The heating unit 400 is activated to preheat the drum 200, and then rice, ingredients, and seasonings are added continuously or in batches from the higher end (feeding end). The rotation of the drum 200 causes the internal materials to tumble, while the stirring spatula 202 further breaks up and mixes the ingredients. Under the influence of gravity and stirring, the materials slowly move along the inner wall of the drum 200 towards the lower end (discharge end), and are automatically discharged from the discharge port after frying. By controlling the feeding speed, the speed of the stirring spatula 202, and the rotation speed of the drum 200, continuous frying operations with simultaneous feeding and discharging can be achieved.

[0035] Based on the above embodiments, the frame 100 is further provided with two sets of abutment portions, each set of abutment portions including at least two abutment wheels 101. The two sets of abutment portions are located at both ends of the length direction of the roller 200 and are symmetrically arranged below or to the side of the roller 200.

[0036] The abutment wheel 101 is mounted on a bracket fixed to the frame 100 via bearings, with its axis parallel to the axis of the roller 200. The wheel surface of the abutment wheel 101 can be made of wear-resistant rubber, polyurethane, or metal-coated material, ensuring support stability while reducing vibration and noise during the rotation of the roller 200. In actual assembly, the roller 200 is not directly rigidly connected to the frame 100 via the main shaft, but is supported on the abutment wheels 101 at four (or more) points. When the roller 200 rotates around its own axis, the abutment wheels 101 rotate freely, forming a low-friction rolling support.

[0037] Abutment rings 203 are fixedly provided at both ends of the outer surface of the roller 200. The abutment rings 203 extend outward along the radial direction of the roller 200, forming an annular flange around the outer circumference of the roller 200. The material of the abutment rings 203 can be integrally formed with the roller 200 body or fixed by welding, bolt connection, or other methods. Correspondingly, two sets of limiting parts are rotatably provided on the frame 100, each set of limiting parts including at least two limiting wheels 102. The two sets of limiting parts are respectively arranged at both ends of the length direction of the roller 200, and located below or to the side below the abutment rings 203. Each limiting wheel 102 is mounted on a bracket on the frame 100 by bearings, and its axis is perpendicular to the axis of the roller 200, so that the wheel surface of the limiting wheel 102 can roll in contact with the side of the abutment ring 203. During operation, the roller 200 is driven by the drive mechanism to rotate around its own axis, while the abutment rings 203 are supported by the limiting wheels 102 on both sides and their axial movement is restricted.

[0038] A transmission rack 204 is fixedly mounted on the outer surface of the roller 200 along its circumference (the abutment ring 203 can be integrated into the transmission rack 204, i.e., the limit wheel 102 abuts against the side of the transmission rack 204). It is coaxially fixed to the roller 200 and can be installed by welding, bolting, or integral molding to ensure no relative slippage occurs during rotation. Correspondingly, a drive unit is fixedly mounted on the frame 100. The drive unit is a geared motor or a servo motor, and its output end is connected to a drive gear 103. The drive gear 103 meshes with the transmission rack 204, forming an external meshing gear and rack transmission pair. When the drive unit starts, it drives the drive gear 103 to rotate. Through the meshing action of the gear and the transmission rack 204, torque is transmitted to the roller 200, thereby driving the roller 200 to rotate stably around its own axis.

[0039] Furthermore, two mounting brackets 104 are fixedly mounted on the frame 100. The two mounting brackets 104 are located on the outer sides of the openings at both ends of the drum 200, and a connecting shaft 105 is rotatably connected between the two mounting brackets 104. The connecting shaft 105 passes through the receiving cavity 201 of the drum 200, and its two ends are rotatably supported on the corresponding mounting brackets 104 by bearing assemblies. The axis of the connecting shaft 105 is parallel to the axis of the drum 200 to ensure the stability of the stirring process.

[0040] The connecting shaft 105 is driven to rotate by an independent stirring drive mechanism (such as a small geared motor). Its rotation direction can be the same as or opposite to that of the drum 200, and its speed can be adjusted independently. Thus, the drum 200 and the stirring shovel 202 form a compound motion: the drum 200 provides overall tumbling and material conveying, while the stirring shovel 202 provides local forced stirring. The two work together to significantly improve the uniformity and efficiency of frying.

[0041] like Figure 2 As shown, a number of stirring shovels 202 are arranged at intervals along the axial direction on the connecting shaft 105. Each three adjacent stirring shovels 202 are arranged in a ring-shaped interval in the circumferential direction, that is, the three are staggered from each other in the circumferential direction of the connecting shaft 105, forming a spiral staggered arrangement.

[0042] Furthermore, the stirring spatula 202 only makes slight contact or abuts against the inner wall of the cavity 201 when rotating to the bottom area of ​​the drum 200 (effectively scraping off rice or sauce residues attached to the heating area, preventing local overheating and scorching, while avoiding increased energy consumption and wear on the inner wall caused by friction throughout the process); while at other angle positions (such as the top and side), an appropriate gap is maintained between the stirring spatula 202 and the inner wall of the drum 200.

[0043] Meanwhile, the connecting shaft 105 is driven by an independent stirring drive mechanism, and its rotation direction is the same as that of the drum 200 (e.g., both are clockwise), but their rotation speeds are different.

[0044] Furthermore, the heating unit 400 includes multiple rows of infrared heating heads fixedly mounted on the frame 100. The infrared heating heads are arranged side-by-side along the axial direction of the drum 200, with each row containing several independently controllable infrared heating units, comprehensively covering the effective frying area at the bottom of the drum 200. The infrared heating heads are securely mounted on the frame 100 via brackets and are located directly below the drum 200, maintaining an appropriate distance from the outer wall of the drum 200. Preferably, the infrared heating heads are made of quartz tubes or ceramic infrared heating elements.

[0045] An insulation box 106 is also fixedly installed on the frame 100. The insulation box 106 is completely surrounded by the outer periphery of the roller 200, forming a closed or semi-closed heat insulation cavity, leaving only the openings at both ends of the roller 200 for materials to enter and exit.

[0046] A support platform 107 is provided below the frame 100. This support platform 107 is fixedly installed on the ground or equipment base to support the weight of the entire machine and provide a stable installation reference. The support foot 300 includes a connecting rod 302 and an adjusting rod 303 (such as an electric push rod or a pneumatic telescopic rod, where the connecting rod 302 is a cylinder housing and the adjusting rod 303 is a cylinder shaft). The middle end of the connecting rod 302 is hinged to the support platform 107 via a pin or hinge structure. Specifically, the support platform 107 has a receiving hole 108. The connecting rod 302 extends from above into the receiving hole 108 and is rotatably connected to the support platform 107 at its middle position via a transverse hinge shaft. The size of the receiving hole 108 is slightly larger than the cross-section of the connecting rod 302, allowing the connecting rod 302 a certain amount of forward and backward movement space within the receiving hole 108.

[0047] A feeding ramp 205 and a discharging ramp 206 are fixedly installed at the two ends of the drum 200, respectively. The feeding ramp 205 is located on the side near the feeding end of the drum 200 and is installed above the mounting bracket 104 at the corresponding end. The feeding ramp 205 is inclined to facilitate the material to slide smoothly into the drum 200 by gravity. The discharging ramp 206 is located on the side near the discharging end of the drum 200 and is installed below the mounting bracket 104 at the corresponding end. The discharging ramp 206 is also inclined to ensure that the material after frying can be quickly and completely discharged from the drum 200 and slide down the ramp to the designated position.
