Description

Technical Field

[0001] This application relates to the technical field of quantitative feeding of slurry, and in particular to a directional feeding device. Background Technology

[0002] Crispy-shell ice cream is a frozen dessert with a crispy chocolate shell and a smooth ice cream core. Its core characteristic is the striking contrast between the crispy exterior and the smooth interior. During production, a temperature difference is used to quickly solidify melted chocolate (often with coconut oil or butter added to accelerate solidification) onto the surface of frozen ice cream, forming the crispy shell. The ice cream core is mainly composed of milk, heavy cream, sugar, and stabilizers, with some recipes adding egg yolks to enhance its smoothness. The crispy shell is mostly made of pure cocoa butter chocolate, and commercial products often include chopped nuts to enrich the texture.

[0003] Currently, in the production of frozen ice cream, for frozen ice cream products with a chocolate shell, a temperature-controlled liquid chocolate is poured over the frozen ice cream base during processing. This allows the chocolate shell to form on the surface of the frozen ice cream base in a low-temperature environment. In continuous production, the temperature-controlled chocolate is placed in a specific chocolate syrup tank. Typically, a discharge pipe and a valve controlling the opening and closing of the discharge pipe are installed at the bottom of the tank. When the frozen ice cream base passes under the syrup tank, the valve opens and a certain amount of chocolate is discharged through the discharge pipe, coating the surface of the ice cream base.

[0004] Regarding the aforementioned technologies, the inventors believe that during the discharge of the slurry, fluctuations in the liquid level in the slurry tank cause variations in the amount of chocolate discharged each time, resulting in inconsistent amounts of chocolate crust on the surface of the same batch of ice cream, thus reducing product standardization. Summary of the Invention

[0005] In order to achieve standardized quantitative feeding of slurry in a single batch and improve the standardization of product production, this application provides a directional feeding device.

[0006] The directional feeding device provided in this application adopts the following technical solution: A directional feeding device includes a hopper, a mounting base, a material extraction component, and an opening and closing component. The mounting base is disposed on its top surface. A feed inlet communicating with the hopper is vertically formed on the top surface of the mounting base. A discharge outlet is vertically formed on the bottom surface of the mounting base. A material extraction port is horizontally formed on the vertical sidewall of the mounting base. A rotating inner cavity is horizontally formed inside the mounting base, communicating with the feed inlet, discharge outlet, and extraction port. The opening and closing component includes a rotating plunger. A first conveying hole and a second conveying hole are formed on the peripheral wall of the rotating plunger. The first conveying hole... The first feeding hole and the second feeding hole are vertically connected. The first feeding hole, the second feeding hole, the inlet, the outlet, and the extraction hole are located in the same vertical plane.

The piston plate is slidably disposed in the extraction cylinder. The extraction cylinder is provided with a driving member for driving the piston plate to move along the length direction of the extraction cylinder.

[0007] By adopting the above technical solution, during pouring, the mounting base rotates until the first feeding hole connects with the inlet and the second feeding hole connects with the outlet. The piston plate moves away from the mounting base, drawing the slurry from the hopper into the extraction cylinder. The rotating plunger rotates 90°, connecting the first feeding hole with the outlet and the second feeding hole with the discharge port. At this point, the inner cavity of the hopper and the inner cavity of the extraction cylinder are separated by the rotating plunger. The piston plate moves in the opposite direction, squeezing the slurry from the extraction cylinder through the discharge port, reducing the impact of slurry agitation in the hopper on the discharge process. The single discharge volume is determined by the volume of the extraction cylinder, which helps improve the standardization of product production. Through the cooperation of the hopper, mounting base, extraction assembly, and opening / closing assembly, standardized quantitative feeding of slurry can be achieved in a single operation, improving the standardization of product production.

[0031] Reference Figure 1 , Figure 2 and Figure 7The silo 1 is equipped with a liquid level detection sensor 11, the detection end of which extends to the bottom of the silo 1. The feeding assembly 5 includes a feeding cylinder 51, a connecting pipe 52, a partition plate 53, a rotating circular plate 54, a connecting rod 55, a sliding sleeve 56, a float ball 57, and a mounting plate 58. The feeding cylinder 51 is located on one side of the silo 1, and the connecting pipe 52 is horizontally connected between the bottom end of the feeding cylinder 51 and the bottom end of the silo 1. The connecting pipe 52 is a circular pipe. The outside of the feeding cylinder 51 is equipped with an insulation jacket layer 12 for heat preservation. A third stirring shaft 13 is rotatably installed in the feeding cylinder 51. A drive source for driving the third stirring shaft 13 to rotate is installed on the feeding cylinder 51, and a feeding stirring frame 14 for stirring the slurry inside the feeding cylinder 51 is installed on the third stirring shaft 13.

[0032] Referring to the figure, a float 57 is disposed in a hopper 1, and a mounting plate 58 is horizontally connected to the inner wall of the hopper 1. A first lifting rod 15 is vertically connected to the top of the float 57, and the first lifting rod 15 passes through the material cover and is slidably disposed therewith. The top of the first lifting rod 15 extends out of the hopper 1 and is horizontally connected to a horizontal connecting rod 16. A second lifting rod 17 is vertically connected to the end of the horizontal connecting rod 16 away from the first lifting rod 15, and the bottom end of the second lifting rod 17 is rotatably connected to a sliding sleeve 56.

[0033] Reference Figure 7 Two partition plates 53 are provided in the connecting pipe 52, and the two partition plates 53 are arranged parallel to each other. The partition plates 53 have partition sector openings 531. A rotating circular plate 54 is sandwiched between the two partition sector plates. The two sides of the rotating circular plate 54 are provided with mounting ring grooves, and sealing bearings are embedded in the mounting ring grooves. The rotating circular plate 54 is sealed and rotatedly connected to the connecting pipe 52 through the sealing bearings. The partition plates 53 have connecting sector openings 541 corresponding to the shape of the partition sector openings 531. The peripheral wall of the connecting pipe 52 has a connecting arc groove 521. One end of the connecting rotating rod 55 extends into the connecting pipe 52 through the connecting arc groove 521 and connects to the edge of the rotating circular plate 54. The sliding sleeve 56 is provided on the connecting rotating rod 55. When the float 57 rises to abut against the bottom surface of the mounting plate 58, the connecting sector openings 541 on the rotating circular plate 54 rotate to be staggered with the partition sector openings 531 on the partition plates 53. When the float ball 57 descends to the bottom of the hopper 1, the connecting fan-shaped opening 541 on the rotating circular plate 54 is rotated to connect with the separating fan-shaped opening 531 on the partition plate 53.

[0034] Reference Figure 1-3During the pouring of the chocolate syrup, temperature-controlled liquid chocolate is injected into the hopper 1. The reducer 29 drives the first stirring shaft 22 to rotate, and the first drive gear 26 drives the linkage gear 28 and the second drive gear 27 to rotate. The first stirring shaft 22 and the second stirring shaft 24 rotate in opposite directions, causing the first stirring frame 21 and the second stirring frame 23 to rotate in opposite directions within the hopper 1, thus stirring the syrup in the hopper 1 to improve its uniformity.

[0035] Reference Figure 1 , Figure 3 and Figure 5 During the material extraction operation, the rotating plunger 31 is rotated until the first feeding hole 311 is connected to the feed inlet 71, and the second feeding hole 312 is connected to the extraction port 73. At this time, the inner cavity of the hopper 1 is connected to the inner cavity of the extraction cylinder 46, and the piston plate 44 is located at the end of the extraction cylinder 46 near the mounting base 7. The extraction cylinder 41 is activated, driving the linkage plate 42 to move away from the mounting base 7. Several piston plates 44 move synchronously in the extraction cylinder 46 under the drive of several piston rods 43, extracting the slurry from the hopper 1. The slurry in the hopper 1 enters the extraction cylinder 46 through the feeding through hole on the rotating plunger 31. The abutting screw 9 limits the movement stroke of the linkage plate 42 on the connecting base 6, thereby controlling the movement stroke of the piston plate 44 in the extraction cylinder 46 and ensuring that the extraction volume remains consistent each time. When it is necessary to adjust the amount of material drawn in a single operation, the limit stroke is adjusted by turning the abutment screw 9. The setting of the adjustment scale 61 makes it convenient for the operator to accurately adjust the position of the abutment screw 9 according to the amount of material drawn in a single operation.

[0036] Reference Figure 1 , Figure 5 and Figure 6 During material discharge, the swing cylinder 33 drives the connecting rod 32 to rotate, causing the rotating plunger 31 to rotate 90° within the rotating cavity 74 of the mounting base 7. At this time, the first feeding hole 311 is connected to the extraction port 73, and the second feeding hole 312 is connected to the discharge port 72. The extraction cylinder 41 drives the linkage plate 42 to move towards the mounting base 7, and several piston plates 44 move synchronously towards the mounting base 7, extruding the slurry in the extraction cylinder 46 through the discharge pipe 10 and pouring it onto the ice cream base below the discharge pipe 10. The rotating plunger 31 and the feeding through hole allow for the connection and separation adjustment between the inner cavity of the hopper 1 and the inner cavity of the extraction cylinder 46. As long as there is enough slurry at the bottom of the hopper 1 to be drawn into the extraction cylinder 46, the extraction amount can be kept consistent each time, reducing the impact of slurry agitation in the hopper 1 on the material discharge process and improving the standardization of product production.

[0037] Reference Figure 2 and Figure 7As the material discharge process proceeds, the liquid level in silo 1 continuously decreases. The float 57 gradually moves downwards with the decreasing liquid level. The float 57, through the first lifting rod 15, the horizontal connecting rod 16, and the second lifting rod 17, drives the sliding sleeve 56 downwards. The sliding sleeve 56 slides on the connecting rotating rod 55, causing the connecting rotating rod 55 to rotate downwards. The connecting rotating rod 55 then drives the rotating disc 54 to rotate between the two partition plates 53. When the float 57 descends to a certain position in silo 1, the connecting sector opening 541 on the rotating disc 54 connects with the partition sector opening 531 on the partition plate 53. At this time, because the slurry level in the feeding cylinder 51 is higher than the slurry level in silo 1, the slurry in the feeding cylinder 51 flows into silo 1 through the connecting pipe 52, achieving timely replenishment of the slurry in silo 1, thus eliminating the need for frequent replenishment by the operator. Because the connecting pipe 52 is connected to the bottom of the silo 1, the possibility of excessive agitation and air introduction into the slurry caused by replenishing from a higher position is reduced. As the liquid level in the silo 1 rises, the float 57 moves upward and drives the connecting rod 55 to rotate upward, causing the connecting fan-shaped opening 541 on the rotating disc 54 to realign with the separating fan-shaped opening 531 on the separator plate 53, thus stopping further replenishment to the silo 1. The liquid level detection sensor detects the liquid level in the silo 1. When the liquid levels in both the silo 1 and the replenishment cylinder 51 drop to a certain height, the liquid level detection sensor sends a signal to the control system, reminding the operator to replenish the slurry in a timely manner.

[0038] Reference Figure 2 The insulation jacket layer 12 keeps the slurry in the feeding cylinder 51 warm, and the feeding mixing frame 14 mixes the slurry in the feeding cylinder 51 evenly. During discharge, the rotating blade rod 103 rotates under the impact of the slurry, driving the two scraper rods 104 to move against the inner wall of the discharge pipe 10, thereby cleaning the inner wall of the discharge pipe 10 and reducing the possibility of excessive slurry adhering to the inner wall of the discharge pipe 10.

[0039] The implementation principle of the directional feeding device in this embodiment is as follows: When pouring chocolate syrup, constant-temperature liquid chocolate is injected into the hopper 1. The stirring component 2 stirs the syrup in the hopper 1 to improve its uniformity. During the extraction operation, the first conveying hole 311 is connected to the inlet 71, and the second conveying hole 312 is connected to the extraction port 73. The extraction cylinder 41 is activated, and the syrup enters the extraction cylinder 46 through the conveying through hole.

[0040] During material discharge, the rotating plunger 31 rotates 90°, and several piston plates 44 move synchronously, extruding the slurry in the extraction cylinder 46 through the discharge pipe 10 and pouring it onto the ice cream base passing below the discharge pipe 10. The rotating plunger 31 and the setting of the material conveying through hole ensure that the amount of material extracted each time is consistent, reducing the impact of slurry agitation in the hopper 1 on the material discharge process and improving the standardization of product production.

[0041] As the discharge process proceeds, the liquid level in silo 1 continuously decreases. When the float 57 descends to a certain position in silo 1, the connecting fan-shaped opening 541 on the rotating circular plate 54 connects with the separating fan-shaped opening 531 on the partition plate 53. The slurry in the replenishing cylinder 51 flows into silo 1 through the connecting pipe 52, achieving timely replenishment of the slurry in silo 1. During discharge, the rotating blade rod 103 rotates under the impact of the slurry, driving the two scraper rods 104 to move against the inner wall of the discharge pipe 10, thus cleaning the inner wall of the discharge pipe 10 and reducing the possibility of excessive slurry adhering to the inner wall of the discharge pipe 10.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
