Description

Technical Field

[0001] This utility model relates to the technical field of meat filling mixing and stirring devices, and in particular to a meat filling mixing and stirring device for roasted sausages. Background Technology

[0002] In the production and processing of sausages, the uniformity of the meat filling directly affects the taste and quality of the sausages. Currently, traditional sausage filling mixing and stirring devices generally suffer from a single feeding structure design, with most having only one feeding port. During processing, workers need to sequentially feed different types of raw materials, such as lean meat, fat, starch, and seasonings, into the mixing tank through this single feeding port. This causes raw materials of different densities and states to naturally form stratification within the mixing tank (e.g., denser meat chunks settle at the bottom, while powdered seasonings float on the surface).

[0003] Because the raw materials are initially distributed in distinct layers, even after stirring, it is difficult to achieve full integration of the various raw materials in a short time. Often, it is necessary to extend the stirring time to achieve the desired mixing effect, which not only reduces production efficiency but may also cause the meat filling to deteriorate due to over-stirring. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixing and stirring device for sausage filling.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a mixing and stirring device for sausage filling, comprising a mixing tank, three support legs fixedly connected circumferentially at intervals at the bottom of the outer peripheral wall of the mixing tank, a raw material mixing hopper coaxially fixedly connected to the top of the mixing tank, a plurality of material input pipes spaced circumferentially at the top of the raw material mixing hopper, each material input pipe communicating with the interior of the raw material mixing hopper, a drive motor fixedly installed at the center of the top of the raw material mixing hopper, the output shaft of the drive motor extending downward in the vertical direction and connected to a crushing and stirring mechanism via a coupling, the crushing and stirring mechanism including a main shaft, the main shaft rotatably connected to the interior of the raw material mixing hopper in the vertical direction, and its lower end extending downward and rotatably connected to the center of the inner bottom wall of the mixing tank, the output shaft of the drive motor being coaxially fixedly connected to the top of the main shaft, a plurality of stirring levers being fixedly connected axially at intervals on the shaft segment of the main shaft located inside the raw material mixing hopper, each stirring lever being evenly distributed circumferentially along the main shaft.

[0006] Preferably, the main shaft is located on a shaft section inside the raw material mixing hopper, and a number of cutting blades are fixedly connected axially between two adjacent stirring rods. Each cutting blade is radially distributed along the circumference of the main shaft. A conveying auger is coaxially fixedly sleeved on the shaft section of the main shaft near the mixing tank body. The outer periphery of the conveying auger is adapted to the inner wall of the lower outlet of the raw material mixing hopper.

[0007] Preferably, a fixed frame is fixedly sleeved on the shaft segment of the main shaft located inside the mixing tank. The fixed frame is a horizontally arranged rectangular frame structure. Two rotating shafts are symmetrically connected to the two opposite inner sidewalls of the fixed frame in the horizontal direction. A plurality of flipping rods are fixedly connected to the outer peripheral wall of each rotating shaft at axial intervals. Each flipping rod extends radially outward along the rotating shaft.

[0008] Preferably, a second drive motor is fixedly installed in the middle of the fixed frame. The output shaft of the second drive motor extends downward in the vertical direction and is coaxially fixedly connected to a driving bevel gear. A driven bevel gear is coaxially fixedly connected to one end of each of the two rotating shafts. The two driven bevel gears mesh with the two sides of the driving bevel gear respectively.

[0009] Preferably, the mixing tank has a discharge structure at the bottom center, which includes a discharge hopper. The top of the discharge hopper is fixedly connected to the discharge port at the bottom of the mixing tank. The bottom of the discharge hopper is fixedly connected to a discharge pipe. Fixed supports are symmetrically fixedly connected to the outer periphery of the discharge pipe. A sealing cover is rotatably connected between the two fixed supports in the horizontal direction. The sealing cover is adapted to the bottom outlet of the discharge pipe and can cover the outlet. A return torsion spring is sleeved on the rotating shaft of the sealing cover. One end of the return torsion spring is fixedly connected to the fixed support, and the other end is fixedly connected to the sealing cover. An operating lever is fixedly connected to the side of the bottom surface of the sealing cover away from the rotating shaft. Pulling the operating lever can drive the sealing cover to rotate around the rotating shaft and cause the return torsion spring to twist. At this time, the sealing cover is disengaged from the outlet of the discharge pipe to open the discharge channel.

[0010] Preferably, a control panel for controlling drive motor one and drive motor two is fixedly provided on one side of the outer peripheral wall of the mixing tank. The control panel is electrically connected to the two motors. A ladder is fixedly provided on the other side of the outer peripheral wall of the mixing tank in a vertical direction. The top of the ladder extends to the height of the raw material mixing hopper.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention, by setting multiple material input pipes on the raw material mixing hopper, allows different types of raw materials to be fed in simultaneously from different feeding channels, avoiding the material stratification phenomenon caused by traditional single feeding ports. Combined with the initial stirring of the stirring lever, pre-mixing can be achieved before the raw materials enter the mixing tank, laying the foundation for subsequent deep mixing and significantly improving the uniformity of the meat filling.

[0013] By avoiding raw material stratification and reducing ineffective mixing time caused by stratification, the multi-stage mixing structure (mixing lever, cutting blade, turning rod, etc.) crushes and mixes the raw materials from multiple directions, both horizontally and vertically, accelerating the raw material fusion speed, shortening the overall processing cycle, and improving efficiency while reducing equipment operating energy consumption.

[0014] The cutting blades can finely crush the raw materials, avoiding large pieces of raw materials remaining. The conveying auger can not only stably transport materials, but also assist in stirring and prevent blockage. The turning rod achieves three-dimensional turning of materials by rotating in the opposite direction, further breaking up local material agglomeration, ensuring that the meat filling has a uniform texture, and improving the taste and quality stability of the finished sausage.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0021] like Figure 1-4As shown, a sausage filling mixing and stirring device is mainly used for mixing different raw materials during sausage production. It solves the problems of material stratification and uneven mixing caused by the single feed inlet in traditional devices. Its specific structure is as follows: The mixing tank 1 is made of food-grade stainless steel and is cylindrical in shape. Its inner wall is smooth and without dead corners, facilitating cleaning and material flow. Both the upper and lower ends of the mixing tank 1 have an arc-shaped transition design. The arc-shaped structure at the lower end guides the material to converge towards the center, facilitating discharge. Three support legs 2 are evenly distributed circumferentially along the bottom of the outer wall of the mixing tank 1 (the angle between adjacent support legs is 120°). They are made of high-strength stainless steel, and the lower ends are welded with anti-slip rubber pads to enhance the stability of the device during placement and prevent displacement due to vibration during operation. The raw material mixing hopper 3 is fixedly connected to the top of the mixing tank 1 and has an inverted funnel-shaped structure. The upper diameter is larger than the lower outlet diameter, facilitating material convergence towards the center. The inner wall of the raw material mixing hopper 3 is also smoothed to reduce material residue. Three to four material input pipes 4 are spaced circumferentially along the top outer periphery of the raw material mixing hopper 3. Each material input pipe 4 is a cylindrical pipe that connects to the interior of the raw material mixing hopper 3. In actual use, different raw materials (such as lean minced meat, fatty minced meat, starch, seasonings, etc.) can be simultaneously fed through different material input pipes 4, avoiding the material stratification problem caused by traditional single feed inlets. Manual valves can be installed on each material input pipe 4 to control the feeding speed and timing. The drive motor 5 is a servo motor, fixedly installed at the center of the top of the raw material mixing hopper 3. Its output shaft extends vertically downwards and is connected to the main shaft 61 of the crushing and mixing mechanism 6 via a coupling, providing power for the entire crushing and mixing process. The main shaft 61 is a solid stainless steel shaft that runs vertically through the raw material mixing hopper 3. Its upper end is fixedly connected to the output shaft of the drive motor 5, and its lower end extends downwards into the mixing tank 1. It is rotatably connected to the center of the inner bottom wall of the mixing tank 1 via bearings, ensuring the stability of the main shaft 61 during high-speed rotation. Stirring rods 62 are axially spaced along the main shaft 61 within the raw material mixing hopper 3 (one group every 10-15 cm), with 3-4 rods per group, radiating evenly around the main shaft 61. The stirring rods 62 are welded perpendicularly to the main shaft 61, are made of stainless steel, and their length is slightly less than the inner diameter of the corresponding position in the raw material mixing hopper 3. When the main shaft 61 rotates, the stirring rods 62 rotate synchronously, initially stirring and mixing the raw materials entering from each material input pipe 4, breaking up the stratification tendency of the raw materials. Cutting blades 64 are fixedly connected to the main shaft 61 within the raw material mixing hopper 3, and are located between adjacent groups of stirring rods 62. The cutting blades 64 are made of stainless steel, fan-shaped, and radially distributed around the main shaft 61 (3-4 blades per group), with the blades facing the direction of rotation. Driven by the main shaft 61, the cutting blades 64 can further chop and refine the raw materials, improving their uniformity.A conveying auger 63 is coaxially and fixedly sleeved on the shaft section of the main shaft 61 near the lower outlet of the raw material mixing hopper 3. The outer periphery of its spiral blades is clearance-fitted with the inner wall of the lower outlet of the raw material mixing hopper 3 (the clearance is no greater than 5mm). When the main shaft 61 rotates, the conveying auger 63 rotates synchronously, spirally pushing the pre-mixed and crushed material in the raw material mixing hopper 3 downwards and smoothly conveying it into the mixing tank 1, while preventing material blockage at the outlet. The fixing frame 65 is a horizontally arranged rectangular stainless steel frame, fixedly sleeved on the middle of the shaft section of the main shaft 61 located inside the mixing tank 1. The side length of the fixing frame 65 is slightly smaller than the inner diameter of the mixing tank 1, and it rotates synchronously with the main shaft 61. Two rotating shafts 66 are symmetrically arranged in the horizontal direction and are rotatably connected to the two opposite inner walls of the fixing frame 65 through bearings, and their axes intersect perpendicularly with the axis of the main shaft 61. The agitator rods 67 are welded axially along the rotating shaft 66 at intervals (one rod every 8-10 cm) and evenly distributed circumferentially along the rotating shaft 66 (3-4 rods per circle). The agitator rods 67 are stainless steel rods, with a length slightly less than the distance from the fixed frame 65 to the inner wall of the mixing tank 1. When the rotating shaft 66 rotates, the agitator rods 67 rotate synchronously, vertically agitating and stirring the material in the mixing tank 1. Combined with the rotational movement of the fixed frame 65, this achieves three-dimensional mixing of the material. The drive motor 68 is fixedly installed in the middle of the fixed frame 65, with its output shaft extending vertically downwards and coaxially fixedly connected to the driving bevel gear 69. The driving bevel gear 69 is located between the two rotating shafts 66, and two driven bevel gears 610 are coaxially fixedly connected to opposite ends of the two rotating shafts 66, both meshing with the driving bevel gear 69. When the drive motor 68 is working, the active bevel gear 69 drives the two driven bevel gears 610 to rotate in opposite directions, which in turn drives the two rotating shafts 66 to rotate in opposite directions, causing the two sets of turning rods 67 to produce stirring actions in opposite directions, thereby enhancing the convective mixing effect of the materials.

[0022] The discharge hopper 91 is funnel-shaped, with its top fixedly connected to the discharge port at the bottom center of the mixing tank 1. It is used to collect the mixed meat filling in the mixing tank 1 into the discharge pipe 92. The discharge pipe 92 is a cylindrical stainless steel pipe, with its top fixedly connected to the bottom of the discharge hopper 91. Its inner diameter is designed according to the required discharge speed (usually 8-12cm). Two fixed supports 93 are symmetrically welded to the lower part of the outer peripheral wall of the discharge pipe 92, forming an "L" shape, to support the rotating structure of the sealing cover 94. The sealing cover 94 is a circular stainless steel plate with a diameter slightly larger than the bottom outlet diameter of the discharge pipe 92. It is rotatably connected between the two fixed supports 93 via a horizontal rotating shaft, and can rotate around the shaft to close or open the outlet of the discharge pipe 92. A food-grade silicone sealing ring is attached to the upper surface of the sealing cover 94 to enhance the sealing performance when closed and prevent material leakage. A reset torsion spring 95 is sleeved on the rotating shaft of the sealing cover 94. One end of the spring is welded to the fixed bracket 93, and the other end is fixedly connected to the side of the sealing cover 94. In its natural state, the elastic force of the reset torsion spring 95 keeps the sealing cover 94 closed at the outlet of the discharge pipe 92. When the operating lever 96 is pulled, the torsion spring is twisted and stores force. After the lever is released, the rebound force of the torsion spring drives the sealing cover 94 to automatically reset and close. The operating lever 96 is a stainless steel rod. One end is vertically welded to the bottom surface of the sealing cover 94 away from the rotating shaft, and the other end extends downward and is equipped with a non-slip handle. By pulling the operating lever 96, the operator can drive the sealing cover 94 to rotate downward around the rotating shaft, opening the discharge channel and allowing the mixed meat filling to be discharged from the discharge pipe 92.

[0023] The control panel is fixedly installed on one side of the outer perimeter of the mixing tank 1 (at a height of 1.5-1.8m for easy operation). It is electrically connected to drive motor 5 and drive motor 68 via wires, allowing control of the start / stop and speed adjustment of both motors (speed range 50-300 r / min). An emergency stop button is also provided to ensure operational safety. A ladder, made of stainless steel, is vertically installed along the other side of the outer perimeter of the mixing tank 1. The ladder steps are spaced 30-40cm apart, extending to the same height as the top of the raw material mixing hopper 3, facilitating operator access for feeding, maintenance, and other operations. Protective handrails are provided on both sides of the ladder to enhance safety.

[0024] Workflow:

[0025] In operation, the operator climbs a ladder to the top of the raw material mixing hopper 3 and adds different types of raw materials (such as lean meat, fatty meat, additives, etc.) to the corresponding material input pipes 4, controlling the feed rate through pipe valves. The drive motor 5 is started, and the main shaft 61 drives the stirring rod 62 and cutting blade 64 to rotate, performing preliminary mixing and crushing of the raw materials. Simultaneously, the conveying auger 63 continuously transports the mixed material into the mixing tank 1. After the material enters the mixing tank 1, the main shaft 61 drives the fixed frame 65 to rotate, while the drive motor 68 drives two rotating shafts 66 to rotate in opposite directions via a bevel gear set, causing the turning rod 67 to agitate and stir the material in multiple directions, achieving deep mixing. After mixing is complete, the operator pulls the operating lever 96 to open the sealing cover 94, and the mixed meat filling is discharged through the discharge hopper 91 and discharge pipe 92 to enter the next production stage. After releasing the lever, the sealing cover 94 automatically closes under the action of the return torsion spring 95.

[0026] This embodiment effectively solves the problems of raw material stratification and uneven mixing in traditional devices by using a multi-inlet design, a multi-stage stirring structure, and a high-efficiency discharge system, thereby improving the processing efficiency and quality of sausage filling.
