Description

Technical Field

[0001] The present application relates to the technical field of food processing equipment, and in particular to a grain adding device for a yogurt cup. Background Art

[0002] In order to meet consumers' demand for diverse taste and rich nutrition, many manufacturers have begun to try to add different kinds of grains to yogurt. However, in the actual production process, how to effectively and evenly add the right amount of grains to each yogurt cup has become an important problem that needs to be solved.

[0003] At present, general adding devices convey grain particles through screw conveyors or vibrating plates, and use sensors to achieve quantitative control. Although this type of equipment can improve production efficiency, it performs poorly when processing grain raw materials with different humidity and density. It fails to fully consider the impact of possible humidity changes in grain raw materials on their fluidity, so it still has certain limitations in practical applications.

[0004] The above-mentioned existing technical means generally have a problem that they cannot effectively deal with the changes in material fluidity caused by environmental factors such as changes in temperature and humidity, thereby affecting the quality stability of the final product. Summary of the invention

[0005] In order to improve the quality stability of the finished product, the present application provides a yogurt cup miscellaneous grain adding device.

[0006] The present application provides a yogurt cup grain adding device, which adopts the following technical solution: A yogurt cup miscellaneous grain adding device, comprising: A material storage tank with a feed inlet at the top; An adding tank is fixedly arranged at the bottom end of the storage tank, and a discharge pipe is connected to the adding tank; Drying components, including: A material containing box, the top of which is open, and the material containing box is slidably connected in the material storage tank, and the sliding direction is vertical; A stirring part, which is arranged on the material containing box and is used to stir the grain particles in the material containing box; A vibration part, two ends of which are respectively connected to the material storage tank and the material holding box, and the vibration part is used to drive the material storage tank to vibrate; A drying part, which is arranged on the material containing box and is used for drying the grain particles in the material containing box; The quantitative component is arranged on the adding tank and is used for quantitatively weighing the weight of the miscellaneous grain particles added at one time.

[0007] By adopting the above technical scheme, the miscellaneous grain particles are put into the storage tank through the feed port, and the stirring part fully stirs the miscellaneous grain particles to avoid agglomeration of the miscellaneous grain particles; during the stirring process, the vibration part causes the storage tank to vibrate, which helps the miscellaneous grain particles to flow in the material box, so that gaps are generated between the miscellaneous grain particles; the drying part uses hot air flow to dry the miscellaneous grain particles in the material box to ensure the dryness of the miscellaneous grain particles; then, the quantitative component realizes the precise control of the weight of the miscellaneous grain particles, ensuring the measurement accuracy of the miscellaneous grain particles during one addition process; It can realize automatic drying, stirring and quantitative addition of grain particles, thereby ensuring the uniformity and dryness of the grain particles during the adding process and improving the adding efficiency and quality.

[0008] Optionally, the stirring unit includes: A stirring motor is fixed on the bottom end of the material containing box; A connecting rod, coaxially connected to the output shaft of the stirring motor and rotatably connected to the material containing box; One end of the stirring rod is fixed on the connecting rod.

[0009] By adopting the above technical solution, the stirring motor drives the connecting rod to rotate, so that the stirring rod can fully stir the miscellaneous grain particles in the material box, ensuring that the miscellaneous grain particles are evenly heated, thereby easily improving the drying efficiency and drying quality.

[0010] Optionally, the vibration unit includes: A driving motor is fixed on the storage tank; A cam is coaxially connected to the output shaft of the driving motor and is located below the material containing box; There are multiple springs, which are arranged around the axis of the storage tank. One end of the spring is fixedly connected to the bottom end of the material holding box, and the other end is fixedly connected to the inner wall of the storage tank through a fixing plate. In the initial state, the spring is in a compressed state.

[0011] By adopting the above technical solution, the output shaft of the driving motor drives the cam to rotate, the tip of the cam squeezes the material box, the elongation of the spring increases, and the spring accumulates elastic force. When the tip of the cam turns away from the material box, the elastic force of the spring causes the material box to vibrate and move up and down, so that the miscellaneous grain particles can bounce up, thereby ensuring good fluidity of the miscellaneous grain particles.

[0012] Optionally, the drying section comprises: There are multiple air guns, which are arranged around the axis of the material holding box and fixed at the open end of the material holding box; An air pump is arranged on the storage tank, and an input end of the air pump is connected to an external hot air source; A hose has one end connected to the output ends of the plurality of air guns, and the other end connected to the output end of the air pump.

[0013] By adopting the above technical solution, the air pump draws hot air from an external hot air source and supplies air to the air gun through a hose. The air gun evenly dries the miscellaneous grain particles in the material box. When the miscellaneous grain particles bounce up, the air gun continues to spray hot air on the miscellaneous grain particles to ensure that the dryness of the miscellaneous grain particles added each time is consistent, thereby easily improving the quality of the yogurt cup product.

[0014] Optionally, the air gun is tilted along the horizontal direction toward the vertical downward direction.

[0015] By adopting the above technical solution, the hot air blown out by the air gun can better cover the miscellaneous grain particles in the material box, thereby improving the drying efficiency, ensuring that the miscellaneous grain particles are evenly heated, avoiding drying dead corners, and thus improving the overall drying effect of the miscellaneous grain particles.

[0016] Optionally, the quantitative component includes: A suction part, both ends of which are connected to the storage tank and the adding tank respectively, and the suction part is used to suck the dried grain particles into the adding tank; A weighing unit is arranged in the adding tank and is used to quantitatively weigh the weight of the miscellaneous grains added at one time; The feeding part is arranged on the weighing part and is used for discharging the weighed grain particles.

[0017] By adopting the above technical scheme, when the miscellaneous grain particles are dried, the moisture content is reduced, so that the weight of the material containing box is reduced, and under the elastic force of the spring, the movement of the material containing box is increased, so that the miscellaneous grain particles bounce higher. When the miscellaneous grain particles bounce to the set height, the suction part sucks the dried miscellaneous grain particles into the adding tank, the weighing part quantitatively weighs the weight of the miscellaneous grain particles added at one time, and the feeding part discharges the weighed miscellaneous grain particles, ensuring that the amount of miscellaneous grain particles added each time is consistent, thereby improving the adding accuracy and efficiency.

[0018] Optionally, the material suction part includes: A suction pipe, both ends of which are connected to the storage tank and the adding tank respectively; The air pump is arranged on the suction pipe.

[0020] Optionally, the weighing unit includes: A weighing telescopic rod is fixedly arranged in the adding tank; A weighing box, the top of which is open, is hinged to the movable end of the weighing telescopic rod through a connecting plate, and the open end of the weighing box is located below the suction tube; A liquid storage box is connected to the rodless cavity of the weighing telescopic rod through a flow guide tube, and water flows through the flow guide tube; A liquid level sensor is fixedly arranged in the liquid storage box and is used to output a liquid level height signal in the liquid storage box; The controller is fixedly arranged in the adding tank and electrically connected to the liquid level sensor. The controller responds to the liquid level height signal output by the liquid level sensor.

[0021] By adopting the above technical scheme, the suction pipe pours the sucked miscellaneous grain particles into the weighing box. Under the gravity of the miscellaneous grain particles, the weighing box squeezes the movable end of the weighing telescopic rod to move, and the internal volume of the rodless cavity of the weighing telescopic rod is reduced. The water in the rodless cavity of the weighing telescopic rod enters the liquid storage box through the guide pipe. The liquid level sensor measures the water in the liquid storage box and outputs the liquid level height signal in the liquid storage box to the controller. The controller accurately detects the liquid level height signal output by the liquid level sensor, thereby realizing accurate weighing of the miscellaneous grain particles.

[0022] Optionally, the feeding part includes: A fixing frame, fixed on the connecting plate; An electric telescopic rod, a fixed end of which is hinged on the fixed frame, and a movable end of which is hinged to the weighing box, and the electric telescopic rod is electrically connected to the controller; A conducting tube is L-shaped, one end of which is connected to the suction tube, and the other end is located above the weighing box; The solenoid valve is arranged on one end of the conducting tube close to the weighing box and is electrically connected to the controller.

[0023] By adopting the above technical solution, when the set value is reached, the controller responds to the liquid level height signal output by the liquid level sensor, and controls the solenoid valve to close, and at the same time controls the active end of the electric telescopic rod to extend, and the active end of the electric telescopic rod pushes the weighing box to rotate, and pours the miscellaneous grain particles in the weighing box into the discharge pipe, thereby realizing the discharge of the weighed miscellaneous grain particles through the conducting pipe, and the opening and closing of the conducting pipe are controlled by the solenoid valve, so as to easily ensure the accurate delivery of the miscellaneous grain particles, thereby improving the accuracy of addition.

[0024] Optionally, the stirring rods are provided in multiple groups, and the multiple groups of stirring rods are arranged along the axis direction of the connecting rod. Each group of stirring rods is provided with multiple stirring rods, and the multiple stirring rods are arranged around the axis of the connecting rod.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: By setting up the stirring part and the vibrating part, the accumulation and agglomeration of the grain particles in the storage tank can be effectively avoided, the fluidity and uniformity of the grain particles are improved, and the problem of uneven addition caused by poor material fluidity in traditional technology is solved; By setting up a drying section, the grain particles can be dried before adding to reduce the deterioration of fluidity caused by excessive humidity, thereby ensuring the consistency of the added amount and the stability of product quality under different environmental conditions; By setting up quantitative components, the precise measurement and automatic transmission of grain particles from the storage tank to the adding tank is achieved, which reduces the errors caused by human intervention and improves the degree of production automation and the consistency of finished product quality.

When the tip of the cam 332 rotates away from the material box 31, the spring 333 drives the material box 31 to vibrate, so that the material box 31 moves up and down, and the grains are bounced up; At the same time, the air pump 342 draws hot air from an external hot air source and supplies air to the air gun 341 through the hose 343. The air gun 341 evenly dries the miscellaneous grain particles in the material box 31. When the miscellaneous grain particles bounce up, the air gun 341 continues to spray hot air on the miscellaneous grain particles to ensure that the dryness of the miscellaneous grain particles added each time is consistent, thereby easily improving the quality of the yogurt cup product.

[0041] Reference Figure 1 and Figure 2The quantitative component 4 includes a suction part 41, a weighing part 42 and a feeding part 43. The suction part 41 includes a suction pipe 411 and an air pump 412. The two ends of the suction pipe 411 are respectively connected to the storage tank 1 and the adding tank 2. The end of the suction pipe 411 located in the storage tank 1 is expanded. The air pump 412 is arranged on the suction pipe 411.

[0042] Reference Figure 2 The weighing part 42 includes a weighing telescopic rod 421, a weighing box 422, a liquid storage box 423, a liquid level sensor 424 and a controller 425. The weighing telescopic rod 421 is vertically arranged and located in the adding tank 2. The weighing telescopic rod 421 is fixed at the center of the bottom end of the adding tank 2.

[0043] Reference Figure 2 The weighing box 422 is rectangular and horizontally arranged, and the side wall of the weighing box 422 in the length direction is inclined away from the vertical axis of the weighing box 422, that is, the vertical cross section of the weighing box 422 is a right-angled trapezoid. The top of the weighing box 422 is open and hinged to the movable end of the weighing telescopic rod 421 through a connecting plate.

The liquid storage box 423 is connected to the rodless cavity of the weighing telescopic rod 421 through a guide tube, and water flows through the guide tube. The liquid level sensor 424 is fixed on the bottom end of the liquid storage box 423 and is used to output the liquid level height signal in the liquid storage box 423. The controller 425 is fixed on the inner wall of the adding tank 2 and is electrically connected to the liquid level sensor 424.

[0045] Reference Figure 2 The feeding part 43 includes a fixed frame 431, an electric telescopic rod 432, a conducting pipe 433 and a solenoid valve 434. The fixed frame 431 is in an L-shaped plate shape and is vertically arranged. The fixed frame 431 is fixed to the connecting plate. The fixed end of the electric telescopic rod 432 is hinged on the fixed frame 431, and the movable end is hinged to the end of the weighing box 422 away from the hinge axis. The electric telescopic rod 432 is electrically connected to the controller 425.

[0046] The conducting pipe 433 is L-shaped and vertically arranged, one end of the conducting pipe 433 is connected to the suction pipe 411, and the other end is located above the weighing box 422, and the end of the conducting pipe 433 away from the suction pipe 411 is in a constricted shape. The solenoid valve 434 is arranged on the end of the conducting pipe 433 close to the weighing box 422 and is electrically connected to the controller 425.

[0047] When in use, after the grains are dried, the weight of the material box 31 decreases, and under the elastic force of the spring 333, the movement of the material box 31 increases, and the grains bounce higher. When the grains bounce to a set height, the vacuum pump 412 draws the grains into the adding tank 2, and the conducting pipe 433 pours the sucked grains into the weighing box 422. Under the gravity of the grains, the weighing box 422 squeezes the movable end of the weighing telescopic rod 421 to move, and the water in the rodless cavity of the weighing telescopic rod 421 enters the liquid storage box 423 through the guide tube. The liquid level sensor 424 measures the water in the liquid storage box 423 and outputs the liquid level height signal in the liquid storage box 423 to the controller 425. The controller 425 accurately detects the liquid level height signal output by the liquid level sensor 424. When the set value is reached, the controller 425 responds to the liquid level height signal output by the liquid level sensor 424, and controls the solenoid valve 434 to close, and at the same time controls the active end of the electric telescopic rod 432 to extend. The active end of the electric telescopic rod 432 pushes the weighing box 422 to rotate, and the miscellaneous grain particles in the weighing box 422 are poured into the guide box 22.

[0048] The implementation principle of the grain adding device for yogurt cup in the embodiment of the present application is as follows: grain particles are put into the storage tank 1 from the feed inlet 11, and the grain particles fall into the material box 31, and the stirring motor 321 drives the stirring rod 323 to rotate, and the stirring rod 323 fully stirs the grain particles in the material box 31; The driving motor 331 drives the cam 332 to rotate, the tip of the cam 332 squeezes the material box 31, and the spring 333 accumulates elastic force. When the tip of the cam 332 rotates away from the material box 31, the spring 333 drives the material box 31 to vibrate, so that the material box 31 moves up and down, and the grains are bounced up. At the same time, the air pump 342 draws hot air from an external hot air source and supplies air to the air gun 341 through the hose 343. The air gun 341 evenly dries the grains in the material box 31. When the grains bounce up, the air gun 341 continues to spray hot air on the grains. When the grains are dried, the weight of the material box 31 decreases, and under the elastic force of the spring 333, the movement of the material box 31 increases, and the grains bounce higher. When the grains bounce to a set height, the vacuum pump 412 draws the grains into the adding tank 2, and the conducting pipe 433 pours the sucked grains into the weighing box 422. Under the gravity of the grains, the weighing box 422 squeezes the movable end of the weighing telescopic rod 421 to move, and the water in the rodless cavity of the weighing telescopic rod 421 enters the liquid storage box 423 through the guide tube. The liquid level sensor 424 measures the water in the liquid storage box 423 and outputs the liquid level height signal in the liquid storage box 423 to the controller 425. The controller 425 accurately detects the liquid level height signal output by the liquid level sensor 424. When the set value is reached, the controller 425 responds to the liquid level height signal output by the liquid level sensor 424, and controls the solenoid valve 434 to close, and at the same time controls the active end of the electric telescopic rod 432 to extend. The active end of the electric telescopic rod 432 pushes the weighing box 422 to rotate, and the miscellaneous grain particles in the weighing box 422 are poured into the guide box 22. The miscellaneous grain particles in the guide box 22 flow into the discharge pipe 21, and the weighed miscellaneous grain particles are discharged through the conducting pipe 433. The opening and closing of the conducting pipe 433 are controlled by the solenoid valve 434, so as to easily ensure the accurate delivery of the miscellaneous grain particles, thereby improving the accuracy of addition.
