Description

Technical Field

[0001] This invention relates to the field of milk stick processing, and more particularly to a sandwich milk stick processing apparatus. Background Technology

[0002] Milk sticks, as a convenient and flavorful dairy snack, are experiencing a continuous increase in market demand. With rising living standards, the demand for milk sticks is growing, and people are placing higher demands on their taste, quality, variety, and form, hoping for more diverse and personalized choices. This is prompting companies to develop more advanced milk stick production equipment to meet market demands.

[0003] Existing milk sticks are typically made by directly mixing different flavored fruits or nuts with the raw materials to form a solid mixture, which is then extruded into shape using milk stick processing equipment. Because the added fruits or nuts are directly mixed with the raw materials, the resulting product can only have a single flavor of cheese, not a filled milk stick where the added fruits or nuts are sandwiched between the raw materials. This limits product diversity and fails to meet market demand. Therefore, the production of truly filled milk sticks currently relies mainly on manual labor. Workers must first roll the raw milk stick material into sheets, then manually place the filling, and then perform wrapping and shaping processes. This method is not only extremely inefficient, but also makes it difficult to ensure a uniform amount of filling in each milk stick, resulting in inconsistent product quality. Furthermore, hygiene is difficult to strictly control, making it unsuitable for large-scale commercial production. Summary of the Invention

[0004] To address the above problems, the present invention aims to provide a sandwich milk stick processing device.

[0005] This invention is implemented by the following technical solution:

[0006] A sandwich milk stick processing device includes an outer skin material feeding mechanism, a sandwich material feeding mechanism, a forming mechanism, a cutting mechanism, and a conveyor belt, all mounted on a frame.

[0007] The outer skin material feeding mechanism's outer skin material outlet is sealed and connected to the outer skin material inlet of the forming mechanism; the sandwich material feeding mechanism's sandwich material outlet is sealed and connected to the sandwich material inlet of the forming mechanism; the forming mechanism's outlet is located directly above the conveyor belt's feeding end; the cutting mechanism is located directly above the middle of the conveyor belt, and the cutting blade of the cutting mechanism is perpendicular to the length direction of the conveyor belt.

[0008] Furthermore, the outer skin raw material feeding mechanism includes an outer skin raw material feeding trough with an open top; an outer skin raw material pressing cover is slidably disposed in the outer skin raw material feeding trough; the cylinder body of the outer skin raw material pressing cylinder is fixedly disposed on the frame, and the telescopic rod of the outer skin raw material pressing cylinder is fixedly connected to the top of the outer skin raw material pressing cover; a plurality of outer skin raw material discharge ports are opened at the bottom of the outer skin raw material feeding trough along the length direction of the outer skin raw material feeding trough;

[0009] A first pressure relief port is provided on the outer raw material pressing cover, and a first pressure relief valve is provided at the first pressure relief port.

[0010] Furthermore, the sandwich material feeding mechanism includes a sandwich material feeding cylinder with an open top; a sandwich material pressing cover is slidably disposed inside the sandwich material feeding cylinder; the cylinder body of the sandwich material pressing cylinder is fixedly disposed on the frame, and the telescopic rod of the sandwich material pressing cylinder is fixedly connected to the top of the sandwich material pressing cover; a plurality of sandwich material outlets are provided at the bottom of the sandwich material feeding cylinder;

[0011] A second pressure relief port is provided on the sandwich material pressing cover, and a second pressure relief valve is provided at the second pressure relief port.

[0012] Furthermore, the molding mechanism includes an elongated molding die, inside which are fixedly arranged a plurality of parallel and horizontally arranged sandwich material injection tubes. Each sandwich material injection tube extends to two opposite side walls of the molding die at both ends and communicates with the outside. An outer material injection tube is fixedly sleeved on the outside of each sandwich material injection tube. One end of each outer material injection tube is closed and placed inside the molding die, while the other end of each outer material injection tube extends to the side wall of the molding die and communicates with the outside.

[0013] One end of the sandwich material injection pipe, away from the outer skin material injection pipe, forms the sandwich material inlet, and the open end of the outer skin material injection pipe forms the outlet of the molding mechanism.

[0014] The top of the molding die has an outer skin material inlet corresponding to the position and number of the outer skin material injection pipes, and each outer skin material inlet is connected to its corresponding outer skin material injection pipe.

[0015] Furthermore, the cutting mechanism includes a cutting cylinder and a cutter; the cylinder body of the cutting cylinder is fixedly mounted on the frame, the telescopic rod of the cutting cylinder is fixedly connected to the back of the cutter, and the length of the cutter matches the width of the conveyor belt.

[0016] Advantages of this invention:

[0017] In this invention, the filling material injection tube is fitted inside the outer material injection tube, so that the milk strips extruded from the outlet of the forming mechanism are in a state where the outer material wraps around the filling material, thus producing continuous, strip-shaped sandwich milk strips. The continuous sandwich milk strips move forward continuously with the conveyor belt. When they reach the cutting mechanism, they are cut into discontinuous sandwich milk strips by a cutter, thus creating truly sandwich milk strips. This enriches the diversity of milk strip products, better meets market demands, reduces worker workload, improves production efficiency, increases the uniformity of the filling, and thus ensures product quality.

[0026] In this embodiment, the outer skin raw material feeding mechanism 2 includes an outer skin raw material feeding trough 21 with an open top; an outer skin raw material pressing cover 22 is slidably disposed in the outer skin raw material feeding trough 21; the cylinder body of the outer skin raw material pressing cylinder 23 is fixedly disposed on the frame 1, and the telescopic rod of the outer skin raw material pressing cylinder 23 is fixedly connected to the top of the outer skin raw material pressing cover 22; a plurality of outer skin raw material outlets are opened at the bottom of the outer skin raw material feeding trough 21 along the length direction of the outer skin raw material feeding trough 21; a first pressure relief port is opened on the outer skin raw material pressing cover 22, and a first pressure relief valve 24 is provided at the first pressure relief port.

[0027] The sandwich material feeding mechanism 3 includes a sandwich material feeding cylinder 31 with an open top; a sandwich material pressing cover 32 is slidably provided inside the sandwich material feeding cylinder 31; the cylinder body of the sandwich material pressing cylinder 33 is fixedly mounted on the frame 1, and the telescopic rod of the sandwich material pressing cylinder 33 is fixedly connected to the top of the sandwich material pressing cover 32; a plurality of sandwich material outlets are provided at the bottom of the sandwich material feeding cylinder 31; a second pressure relief port is provided on the sandwich material pressing cover 32, and a second pressure relief valve 34 is provided at the second pressure relief port.

[0028] The molding mechanism 4 includes a long strip-shaped molding mold 41. Several parallel and horizontally arranged sandwich material injection tubes 42 are fixedly installed inside the molding mold 41. Both ends of each sandwich material injection tube 42 extend to two opposite side walls of the molding mold 41 and are connected to the outside. An outer skin material injection tube 43 is fixedly sleeved on the outside of each sandwich material injection tube 42. One end of each outer skin material injection tube 43 is closed and placed inside the molding mold 41, while the other end of each outer skin material injection tube 43 extends to the side wall of the molding mold 41 and is connected to the outside. One end of the sandwich material injection tube 42 away from the outer skin material injection tube 43 forms a sandwich material inlet, and the open end of the outer skin material injection tube 43 forms the outlet of the molding mechanism 4. An outer skin material inlet 44 is opened on the top of the molding mold 41, corresponding to the position and number of the outer skin material injection tubes 43. Each outer skin material inlet 44 is connected to its corresponding outer skin material injection tube 43.

[0029] The cutting mechanism 5 includes a cutting cylinder 51 and a cutter 52; the cylinder body of the cutting cylinder 51 is fixedly mounted on the frame 1, the telescopic rod of the cutting cylinder 51 is fixedly connected to the back of the cutter 52, and the length of the cutter 52 is matched with the width of the conveyor belt 6.

[0030] In this embodiment, valves are provided at both the outer skin material outlet and the filling material outlet. When the equipment malfunctions or is shut down for maintenance, the valves can be closed to prevent waste of raw materials.

[0031] Job Description:

[0032] Before using this embodiment, close all valves at the discharge port, then mix the outer skin material, mainly milk powder, in the dough mixing pot and add it to the outer skin material feeding tank 21. Prepare the pre-filled fruit pieces or nuts into a viscous slurry in advance and add it to the filling material feeding cylinder 31.

[0033] After loading, open the valves at each discharge port and activate the outer skin material pressing cylinder 23 and the sandwich material pressing cylinder 33 respectively. This extends the cylinder's telescopic rod, causing the outer skin material pressing cover 22 and the sandwich material pressing cover 32 to move downwards, thus compressing the outer skin material and the sandwich material respectively. During the downward movement of the outer skin material pressing cover 22 and the sandwich material pressing cover 32, the first pressure relief valve 24 and the second pressure relief valve 34 can be opened to ensure that the outer skin material pressing cover 22 and the sandwich material pressing cover 32 can move normally.

[0034] During the gradual compression process, the outer skin material enters the outer skin material injection tube 43 through the outer skin material inlet 44 on the molding die 41, and the filling material enters the filling material injection tube 42 through the filling material inlet on the molding die 41. Finally, both are squeezed out through the outlet of the molding mechanism 4. Since the filling material injection tube 42 is sleeved inside the outer skin material injection tube 43, the milk strip squeezed out by the outlet of the molding mechanism 4 is in a state where the outer skin material wraps the filling material, thus pressing out a continuous, strip-shaped filled milk strip.

[0035] The continuous sandwich milk strips fall onto the conveyor belt 6 below under the action of gravity. Since the conveyor belt 6 is in a moving state, the milk strips that are continuously squeezed out move forward with the conveyor belt 6. When they move to the cutting mechanism 5, the cutter 52 is driven by the cutting cylinder 51 to move up and down at a certain frequency. When the cutter 52 moves down to the surface of the conveyor belt 6, the cutter 52 will cut the continuous sandwich milk strips, thus forming intermittent sandwich milk strips, which continue to move forward on the conveyor belt 6. When they reach the unloading end of the conveyor belt 6, they automatically fall onto the receiving tray 7 placed at the unloading end of the conveyor belt 6.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
