TECHNICAL FIELD
[0001] The present application relates to the field of French fries production, more particularly, to a precise control quantity salt adding equipment for French fries production line. BACKGROUND
[0002] French fries is a snack made of potato strips by frying, which is classified as leisure food. The finished product has the characteristics of crisp outside and soft inside, and potato aroma and crispness. It is often served with ketchup, salt and other condiments. When making, the potatoes are cut into strips, soaked and drained. The shape is kept intact by freezing. The oil temperature needs to be controlled and fried in stages. Some methods use breading or air fryers to improve crispness or reduce oil. In the production process of French fries, traditional electric heating or direct-fired fryers are difficult to meet the yield and cost control requirements of French fries. Therefore, the fryer with boiler and heat exchanger cooperation using heat transfer oil or steam as medium is more common in the French fries processing industry.
[0003] When making in large quantities, the potatoes need to be soaked to remove starch, blanched or frozen to ensure the taste. The outer layer is often coated with starch to enhance crispness. Salt is the main seasoning, and some methods add green pepper salt and five-spice powder to enhance the flavor. There are mainly two ways to add salt in food processing plants: one is to manually pour salt particles or salt powder into the container, and the other is to use a simple pipeline to deliver salt to the tank opening. Both methods have no special flow guide and uniform material design. Salt is concentrated in the local area of the mixing tank, and needs to rely on the stirring function of the mixing tank to achieve mixing. In the prior art, when manually feeding or using a simple pipeline to deliver, salt is prone to accumulate in the mixing tank. The mixing tank needs to be continuously operated for 10-15 minutes to make the salt evenly dissolved, which leads to large fluctuations in the salt concentration of the slurry and affects the quality of the subsequent production process.

[0011] Further, the inner side of the processing tank is provided with a striking component, and the striking component comprises a first bevel gear fixedly connected to the outer side of the rotating rod.

[0022] The inside of processing tank 1 is provided with quantitative assembly 29.
[0023] By adopting the above technical scheme, after the salt material is injected into the inside of the treatment tank 1 through the hopper 12 above the top cover 11, the salt material will be collected by the collecting disc 22, at this time the guide groove 23 opened by the collecting disc is blocked by the blocking claw 24, when the blocking claw 24 is separated from the inside of the guide groove 23 in cooperation with the quantitative assembly 29, the salt material above the collecting disc 22 will fall on the outside of the rotating disc 25 through the guide groove 23, in this process, the driving motor 13 will drive the rotating rod 14 to rotate, so that the rotating rod 14 drives the rotating disc 25 to rotate in the inside of the treatment tank 1, and after the rotating disc 25 rotates, part of the salt material will pass through the rotating disc 25 through the plurality of through holes 26, and then be discharged through the discharge groove 28, and the salt material not entering the inside of the through hole 26 will stay on the outside of the rotating disc 25 and be separated by the plurality of separation strips 27, after the rotating disc 25 rotates, the salt material staying on the surface of the rotating disc 25 will be thrown out and finally be discharged by the discharge groove 28 at the outermost layer. Since the salt material contacts the rotating disc 25, part of the salt material will be dispersed and discharged through the plurality of through holes 26, and the salt material not entering the through hole 26 will be discharged from the outermost discharge groove 28 to the subsequent processing equipment, effectively avoiding the phenomenon that the salt material is accumulated after being discharged to the subsequent processing equipment.
[0024] As shown in Figures 2 to 6 and Figure 8 , the quantitative assembly 29 includes a connecting plate 291 fixedly connected to the left and right sides in the inside of the treatment tank 1.
[0025] The lower side of the collecting disc 22 is fixedly connected to a limiting rod 293 in a ring array, the bottom end of the limiting rod 293 is fixedly connected to a striker 295, the inner side wall of the treatment tank 1 is fixedly connected to a limiting cylinder 294 in a ring array, the limiting rod 293 is slidingly connected to the inside of the limiting cylinder 294, the inside of the limiting cylinder 294 is provided with a pressure sensor 297 at the lower side, the bottom end of the limiting rod 293 and the inside of the limiting cylinder 294 are fixedly connected to a first pressure spring 296, and the striker 295 is in extrusion contact with the upper side of the pressure sensor 297 after moving downward.
[0026] The upper side of the connecting plate 291 is provided with an electromagnet 292, the upper side of the electromagnet 292 is magnetically repelled from the lower side of the blocking claw 24, the shape of the limiting rod 293 is matched with the shape of the limiting cylinder 294, the first pressure spring 296 surrounds the outside of the striker 295, and the front side of the treatment tank 1 is provided with a control panel.
[0027] By adopting the above technical scheme, after the salt material is filled into the receiving disc 22, with the increase of the weight of the salt material, the receiving disc 22 as a whole moves downward, and the limiting rod 293 moves downward in the limiting cylinder 294, and at the same time, the limiting rod 293 extrudes the first pressure spring 296, when the striker 295 below the limiting rod 293 contacts the pressure sensor 297 and reaches the preset value input by the control panel, the pressure sensor 297 transmits information to the controller in the control panel, and then the electromagnet 292 above the connecting plate 291 is controlled by the control panel, so that the magnetism generated by the electromagnet 292 repels the blocking claw 24, and after the blocking claw 24 is lifted, the salt material will be discharged through the guide groove 23, and with the complete discharge of the salt material above the receiving disc 22, the first pressure spring 296 pushes the limiting rod 293 to the uppermost position in the limiting cylinder 294, at this time, the repulsion of the electromagnet 292 to the blocking claw 24 is removed, at this time, the blocking claw 24 moves downward and enters the inside of the guide groove 23, in this process, the limiting ring 241 above the blocking claw 24 will be lapped inside the receiving disc 22, so that the blocking claw 24 cannot pass below the receiving disc 22, because the receiving disc 22 collects the salt material, the weight of the salt material can be detected by the pressure sensor 297, so as to achieve the purpose of quantitative control of the salt material, and at the same time, the blocking of the blocking claw 24 to the guide groove 23 is always maintained before the weight of the salt material reaches the preset value.
[0028] As shown in Figure 5 and Figure 7 , the inside of the processing tank 1 is provided with an impact component 3, and the impact component 3 includes a first bevel gear 31 fixedly connected to the outer side of the rotating rod 14.
[0029] The inside right side of the top cover 11 is rotatably connected with a second bevel gear 33, the outer side of the rotating rod 14 is sleeved with a positioning sleeve 32, the other side of the second bevel gear 33 is rotatably connected to the right side of the positioning sleeve 32, the outer side of the sleeve 21 is fixedly connected with a third bevel gear 34, the front and back sides of the sleeve 21 are both fixedly connected with a fixed plate 35, the sides away from each other of the front and back fixed plates 35 are both hingedly connected with an impact hammer 38, the left and right sides of the fixed plate 35 are both fixedly connected with a baffle 36 in an inclined manner, and the opposite surfaces of the baffle 36 and the impact hammer 38 are both fixedly connected with a second pressure spring 37.
[0030] The first bevel gear 31, the second bevel gear 33 and the third bevel gear 34 are all inside the top cover 11, the positioning sleeve 32 is between the first bevel gear 31 and the third bevel gear 34, and the third bevel gear 34 is hollowly arranged.
[0031] By adopting the above technical scheme, when the driving motor 13 drives the rotating rod 14 to rotate, the first bevel gear 31 outside the rotating rod 14 is driven to rotate. Since the first bevel gear 31 outside the rotating rod 14 and the third bevel gear 34 outside the sleeve 21 are both engaged with the second bevel gear 33, and the two sides of the second bevel gear 33 are respectively connected with the inner wall of the top cover 11 and the positioning sleeve 32 outside the rotating rod 14, when the first bevel gear 31 drives the second bevel gear 33 to rotate, the second bevel gear 33 will drive the sleeve 21 to rotate through the third bevel gear 34. After the sleeve 21 rotates, the fixed plate 35 outside the sleeve 21 will drive the impact hammer 38 to rotate. Since the second pressure spring 37 is fixed between the impact hammer 38 and the baffle 36, when the impact hammer 38 contacts the hopper 12, the impact hammer 38 will extrude one of the second pressure springs 37. When the impact hammer 38 completely passes through the hopper 12, the impact hammer 38 is quickly reset through the second pressure spring 37, and quickly hits the hopper 12 through inertia, so that the salt material attached to the inner wall of the hopper 12 falls due to vibration. Since the impact hammer 38 will generate inertia after passing through the hopper 12 due to the tension of the second pressure spring 37, the impact hammer 38 quickly impacts the hopper 12, effectively avoiding that part of the salt material is attached to the inner wall of the hopper 12, thereby avoiding that the proportion of the salt material and the processed material is affected, and thereby ensuring the quality of the subsequent processed material.
[0032] Working principle: After the salt material is injected into the processing tank 1 through the hopper 12 above the top cover 11, the salt material is collected by the collecting disc 22. At this time, the guide groove 23 opened by the collecting disc is blocked by the blocking claw 24. As the weight of the salt material increases, the collecting disc 22 drives the limiting rod 293 to move downward in the limiting cylinder 294. When the plunger 295 below the limiting rod 293 contacts the pressure sensor 297 and reaches the preset value input by the control panel, the magnetism generated by the electromagnet 292 above the connecting plate 291 repels the blocking claw 24. After the blocking claw 24 is lifted, the salt material above the collecting disc 22 falls outside the rotating disc 25 through the guide groove 23. In this process, the driving motor 13 drives the rotating rod 14 and the rotating disc 25 below it to rotate. At this time, part of the salt material passes through the rotating disc 25 through the plurality of through holes 26, and then is discharged through the discharge groove 28. The salt material not entering the through holes 26 is separated by the plurality of separation strips 27, and then is thrown to the outermost discharge groove 28 for discharge. When the driving motor 13 drives the rotating rod 14 to rotate, the first bevel gear 31 outside the rotating rod 14 is driven to rotate, so that the first bevel gear 31 drives the third bevel gear 34 and the sleeve 21 below it to rotate through the second bevel gear 33, so that the fixed plate 35 outside the sleeve 21 drives the impact hammer 38 to rotate. When the impact hammer 38 contacts the hopper 12, the impact hammer 38 will extrude one of the second pressure springs 37. When the impact hammer 38 completely passes through the hopper 12, the impact hammer 38 is quickly reset through the second pressure spring 37, and quickly hits the hopper 12 through inertia, so that the salt material attached to the inner wall of the hopper 12 falls due to vibration.
[0033] The above description is only the preferred embodiment of the present application; the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent substitutions or changes according to the technical solution and the improvement concept of the present application within the technical scope disclosed by the present application, which should be covered in the protection scope of the present application.
