[0001] The invention relates to the technical field of food processing, in particular to a cheese powder mixing device. Background Art

[0002] When cheese food is produced and processed, a mixing device is needed to replace manual stirring during the material mixing process. For example, in the prior art, a patent document with a publication number of CN212457899U discloses a mixing device for cheese production, comprising: a base, a gear ring is rotatably provided on the top of the base, and a stirring pot is fixedly provided on the upper surface of the gear ring; a stirring mechanism, the stirring mechanism is arranged on the right side of the base, wherein the stirring mechanism comprises a support rod vertically arranged on the base, a support plate is arranged on the top of the support rod, a bracket is arranged on the left side of the support plate, and a driving mechanism is arranged on the right side, and the driving mechanism is connected to the stirring rod. When the device is used to mix two or more raw materials, the raw materials can be fully and evenly mixed, and the working efficiency is high.

[0003] In the actual processing process, such as when producing cheese balls, since cheese balls are easy to stick to each other, it is necessary to coat the surface of them with a layer of cheese powder (or flour, bread crumbs, etc.). The cheese balls and cheese powder are mixed and stirred using the above-mentioned mixing device. The cheese powder cannot be well coated on the surface, and the cheese balls often stick to each other, causing inconvenience to subsequent production. Based on this, the existing mixing device has the problem of poor anti-sticking effect, which needs to be further improved. Summary of the invention

[0004] The purpose of the present invention is to solve the disadvantage of poor anti-adhesion effect of the mixing device in the prior art, and to propose a cheese powder mixing device.

The cheese powder moves to the upper side of the mixing drum with the circular motion of the spiral blades, and then enters the mixing drum again to achieve recycling.

[0010] Preferably, the intermittent control mechanism includes a connecting tube embedded in the feed shaft, and each storage trough is connected to the feed hole through the connecting tube. A valve stem is slidably installed inside the connecting tube, and a valve plug is fixedly installed on the end of the valve stem. An excitation coil is wrapped around the outside of the connecting tube. The magnetic field generated by the excitation coil adsorbs the valve stem, so that the valve plug covers the end of the connecting tube.

[0011] The intermittent control mechanism also includes a first electrode sheet and a second electrode sheet, which are respectively embedded in the surface of the rear end of the feeding shaft, and the two poles of the external power supply are electrically connected to the two ends of the excitation coil through wires, wherein the two ends of the disconnected wire are electrically connected to the first electrode sheet and the second electrode sheet respectively, and a connecting ring is fixedly installed at the end of the rotating sleeve, and a plurality of third electrode sheets are embedded on the inner side of the connecting ring.

[0014] The present invention has the following beneficial effects:

[0015] 1. The mixing device proposed by the present invention has a rotating sleeve and a rotating roller rotating in relative directions arranged therein, and the convex strips on the surface of the rotating roller are used to extrude the transmission sleeve to extrude the cheese into cheese balls. Since the transmission sleeve and the feeding trough are filled with cheese powder, the cheese balls are extruded and formed in the cheese powder, so that the powder coated on the surface of the cheese balls is not easy to fall off, thereby solving the problem of cheese balls sticking to each other. The mixing drum is then used for screening, so that the extrusion, coating and screening processes of food processing are completed at one time, thereby improving production efficiency and product quality.

[0016] 2. During the production process, the rotating sleeve and the rotating roller rotate in relative directions, and the inner cavity of the transmission sleeve and the feeding trough are combined to hold more cheese powder, avoiding the cheese balls from sticking to the inner cavity of the transmission sleeve and the inner wall of the feeding trough. Since the transmission sleeve performs telescopic movement, the discharge nozzle is fixed, and the end of the discharge nozzle can push the cheese balls into the feeding trough. As the rotating roller rotates, the mouth of the feeding trough faces downward and discharges the cheese balls, achieving the effect of convenient material removal and providing convenience for continuous production.

[0017] 3. By setting an intermittent control mechanism, the rhythm of the material input from the feeding hole to the storage tank can be controlled, that is, when the discharge nozzle turns to the side facing the rotating roller, the third electrode sheet conducts the first electrode sheet and the second electrode sheet to supply power to the excitation coil. The magnetic field generated by the excitation coil attracts the valve stem to move, and the valve plug closes the connecting pipe, so that a closed chamber is formed in the storage tank, and the extrusion disk can squeeze out the material in the storage tank. Since the amount of material in the storage tank is constant, the amount squeezed out by the extrusion disk is constant, so that the cheese balls produced are of the same size;

[0018] When the discharge nozzle moves downward, the third electrode sheet separates from the first electrode sheet and the second electrode sheet, the excitation coil is de-energized, and the connecting pipe is opened, so that the material in the feed hole enters the storage tank through the connecting pipe to replenish the loss until the valve plug closes the connecting pipe. This cycle is repeated to achieve continuous cheese ball production. This design realizes a positive correlation between the rotation speed of the rotating sleeve and the feeding rhythm, and solves the problem of mismatch between the feeding rhythm and the rotation rhythm of the rotating sleeve, which may lead to quality problems such as lack of material in the product.

The first gear 9 drives the second gear 30 to rotate through the transmission of the synchronous wheel and the synchronous belt. Figure 2 This part belongs to the conventional setting of the prior art and will not be described in detail here.

[0034] A plurality of discharge components are fixedly mounted on the surface of the rotating sleeve 7, wherein the discharge component comprises a mounting plate 10 fixedly mounted on the surface of the rotating sleeve 7, a plurality of assembly holes are opened on the surface of the mounting plate 10, and a discharge nozzle 11 is fixedly mounted in each assembly hole, a transmission sleeve 12 is slidably sleeved on the outer side of each discharge nozzle 11, a transmission rod 13 is fixedly mounted on the end surface of the transmission sleeve 12, an extrusion disk 14 is fixedly mounted on the bottom end of the transmission rod 13, a guide tube 15 is fixedly mounted inside the extrusion disk 14, and the guide tube 15 is slidably inserted into the discharge nozzle 11, and a reset spring 35 is sleeved on the surface of the transmission rod 13 to press against the transmission sleeve 12, see for details Figure 5 .

[0035] A plurality of material storage grooves 16 are provided on the surface of the feeding shaft 6 , and a feeding hole 17 is provided at the axis of the feeding shaft 6 . Each material storage groove 16 is connected to the feeding hole 17 through an intermittent control mechanism.

[0036] The intermittent control mechanism includes a connecting pipe 23 embedded in the feed shaft 6. Each storage tank 16 is connected to the feed hole 17 through the connecting pipe 23. A valve stem 24 is slidably installed inside the connecting pipe 23. A valve plug 25 is fixedly installed at the end of the valve stem 24. An excitation coil 26 is wound around the outside of the connecting pipe 23. The valve stem 24 is a permanent magnet. The magnetic field generated by the excitation coil 26 attracts the valve stem 24, so that the valve plug 25 covers the end of the connecting pipe 23. Figure 6 .

[0037] refer to Figure 7 The intermittent control mechanism also includes a first electrode sheet 27 and a second electrode sheet 28, which are respectively embedded in the surface of the rear end of the feeding shaft 6, and the two poles of the external power supply are electrically connected to the two ends of the excitation coil 26 through wires, and the two ends of one wire disconnection are electrically connected to the first electrode sheet 27 and the second electrode sheet 28 respectively.

[0038] A connecting ring 31 is fixedly installed at the end of the rotating sleeve 7, and a plurality of third electrode sheets 29 are embedded on the inner side of the connecting ring 31. The connecting ring 31 rotates on the surface of the feeding shaft 6 so that the inner surface of the third electrode sheet 29 is in sliding contact with the outer surfaces of the first electrode sheet 27 and the second electrode sheet 28. What needs to be strengthened is that the connecting ring 31 rotates synchronously with the rotating sleeve 7, that is, when the rotating sleeve 7 rotates to a fixed angle position, the first electrode sheet 27 and the second electrode sheet 28 are in contact with the third electrode sheet 29 to realize the conduction of the power supply circuit of the excitation coil 26.

[0039] The surface of the rotating roller 8 is provided with a plurality of raised strips 18, and the surface of each raised strip 18 is provided with a material distribution groove 19. When the rotating sleeve 7 and the rotating roller 8 rotate synchronously, the raised strips 18 squeeze the transmission sleeve 12, drive the squeezing disc 14 to slide into the storage groove 16, and control the rhythm of material conveying under the action of the intermittent control mechanism, so that the material in the storage groove 16 is intermittently discharged from the discharge nozzle 11 to the material distribution groove 19. Figure 6 .

[0040] refer to Figure 5 During the production process, the rotating sleeve 7 and the rotating roller 8 rotate in relative directions, and the raised strip 18 is in a V-shaped state at the initial moment of contact with the transmission sleeve 12, so that the falling material can be introduced into the feeding groove 19 and the transmission sleeve 12. The inner cavity of the transmission sleeve 12 and the feeding groove 19 are combined to hold more cheese powder 33, and avoid the cheese ball 34 from sticking to the inner cavity of the transmission sleeve 12 and the inner wall of the feeding groove 19. Since the transmission sleeve 12 is squeezed by the raised strip 18 to perform a telescopic action, the discharge nozzle 11 is fixed, and the end of the discharge nozzle 11 can push the cheese ball 34 into the feeding groove 19. As the rotating roller 8 rotates, the mouth of the feeding groove 19 faces downward and discharges the cheese ball 34, so as to achieve the effect of convenient material removal and provide convenience for continuous production.

[0041] In this embodiment, by setting an intermittent control mechanism, the rhythm of the material input from the feed hole 17 to the storage tank 16 can be controlled, that is, Fig. 9 As shown, when the discharge nozzle 11 turns to the side facing the rotating roller 8, the third electrode sheet 29 conducts the first electrode sheet 27 and the second electrode sheet 28 to supply power to the excitation coil 26. The magnetic field generated by the excitation coil 26 attracts the valve stem 24 to move, and the valve plug 25 closes the connecting pipe 23, so that a closed chamber is formed in the storage tank 16, so that the extrusion disk 14 can extrude the material in the storage tank 16. Since the amount of material in the storage tank 16 is constant, the amount extruded by the extrusion disk 14 is constant, so that the cheese balls 34 produced are of uniform size.

[0042] like Figure 8 As shown, when the discharge nozzle 11 moves downward, the third electrode sheet 29 is separated from the first electrode sheet 27 and the second electrode sheet 28, the excitation coil 26 is powered off, and the connecting pipe 23 is opened, so that the material in the feed hole 17 can enter the storage tank 16 through the connecting pipe 23 to replenish the loss until the valve plug 25 closes the connecting pipe 23 (i.e. Fig. 9 The design realizes a positive correlation between the rotation speed of the rotating sleeve 7 and the feeding rhythm of the intermittent control mechanism, thereby solving the quality problem of product shortage due to mismatch between the feeding rhythm and the rotation rhythm of the rotating sleeve 7.

[0043] The mixing device proposed in the present invention is internally provided with a rotating sleeve 7 and a rotating roller 8 rotating in relative directions. The raised strips 18 on the surface of the rotating roller 8 are used to extrude the transmission sleeve 12 to extrude the cheese into cheese balls 34. Since the transmission sleeve 12 and the distribution trough 19 are filled with cheese powder 33, the cheese balls 34 are extruded and formed in the cheese powder 33, so that the powder coated on the surface of the cheese balls 34 is not easy to fall off, thereby solving the problem of the cheese balls 34 sticking to each other. The mixing drum 2 is then used for screening, so that the extrusion, coating and screening processes of food processing are completed at one time, thereby improving production efficiency and product quality.

[0044] Working principle: Before use, pump the cheese raw material into the feeding hole 17, maintain a certain pressure, add the cheese powder 33 into the chassis 1 from the feeding hopper 22, drive the motor 4 to rotate, drive the rotating sleeve 7, the rotating roller 8 and the mixing drum 2 to rotate synchronously (the rotation direction is as follows Figure 3 (indicated by the dashed arrow in the middle);

[0045] When it rotates to Figure 8 When the valve plug 25 is in the open position, the cheese raw material enters the storage tank 16 through the connecting pipe 23, and the cheese powder 33 falls from top to bottom and falls into the transmission sleeve 12 and the distribution tank 19 (as shown in FIG. Figure 4 shown);

[0046] When it rotates to Fig. 9 When the position is shown, the third electrode sheet 29 conducts the first electrode sheet 27 and the second electrode sheet 28, and the external power supply supplies power to the excitation coil 26. The magnetic field generated by the excitation coil 26 attracts the valve stem 24 to move, so that the valve plug 25 closes the connecting pipe 23. Since the raised strips 18 on the surface of the rotating roller 8 squeeze the transmission sleeve 12, the squeezing disc 14 is pushed into the storage tank 16, and the cheese in the storage tank 16 is squeezed and enters the discharge nozzle 11 through the guide tube 15, and the cheese ball 34 is squeezed out from the discharge nozzle 11. Figure 5 As shown, the surface of the cheese ball 34 is covered with cheese powder 33. As the rotating sleeve 7 and the rotating roller 8 rotate, the mouth of the feeding groove 19 faces downward and discharges the cheese ball 34. The cheese ball 34 falls into the mixing drum 2 and continues to mix with the cheese powder 33. Figure 4 As shown;

[0047] When the mixing drum 2 rotates, the cheese powder 33 is screened to the bottom of the inner cavity of the chassis 1, and the cheese balls 34 remain in the mixing drum 2. The spiral blades 20 move in a circle to push the cheese powder 33 to the upper side of the mixing drum 2, so that the cheese powder 33 can be sprinkled from the upper side into the mixing drum 2 for recycling. At the same time, the spray pipe 21 sprays air and cheese powder mixed material to replenish the loss of cheese powder 33, and at the same time blows the surface of the mixing drum 2 to prompt the cheese powder 33 to pass through the filter holes of the mixing drum 2. Finally, the cheese balls 34 can be discharged from the front opening of the mixing drum 2, and the cheese powder 33 holes in the chassis 1 are discharged from the discharge valve 32.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
