Technical Field

[0001] The invention relates to the technical field of food, in particular to the technical field of tapioca pearl granulators. Background Art

[0002] The pearls in bubble tea are also called tapioca pearls. They are generally made from starch powders such as tapioca flour and glutinous rice flour with certain other auxiliary ingredients added. Due to their large usage, they are generally produced in batches by machinery. In the production process, it is generally necessary to first prepare the masterbatch, then shape the masterbatch, and then go through the steps of steaming, cooling, and packaging. The masterbatch is generally made using a pelletizer.

[0003] The existing patent CN220499228U discloses a pelletizing device for taro ball production, in which pelletizing is performed on a conveyor belt. Since the cutting knife used for pelletizing is relatively sharp, after long-term use, the cutting knife is likely to damage the conveyor belt, affecting the service life of the conveyor belt.

[0004] The existing patent CN218534688U discloses a pelletizing device for producing water taro balls, wherein the pelletizing is performed on a cutting board. When cutting, the cutting board collides with the cutting board, and the cutting blade is easily damaged by the collision, which affects the service life of the cutting blade.

[0018] In order to prevent the tapioca pearls from rolling down from both sides of the conveyor belt 6 , two blocking bars 60 are provided above the conveyor belt 6 , and the two blocking bars 60 are respectively located on both sides of the conveyor belt 6 .

[0019] In order to prevent the tapioca pearls from rolling down from both sides of the material guide plate 5 , blocking plates 50 are provided on both sides of the material guide plate 5 .

[0020] In order to ensure that the dry starch can fully contact with the extruded starch strips and at the same time ensure that the dry starch does not fall off too quickly, the extrusion tube 20 is horizontally arranged. There are several extrusion tubes 20, which are arranged horizontally. The length direction of the discharge port 30 is consistent with the arrangement direction of the extrusion tubes 20, and the distance between the inner wall of the discharge port 30 aligned with the extrusion tube 20 and the extrusion tube 20 is greater than the inner diameter of the extrusion tube 20.

[0021] The discharge bin 25 is funnel-shaped.

[0022] Embodiment 2: See also Figure 2Two screws 21 are installed in the feeding bin 2. The spiral directions of the two screws 21 are opposite and the two screws 21 are parallel to each other. The power device is composed of a first motor 23 and a gearbox 22. The first motor 23 is connected to the input shaft of the gearbox 22. The gearbox 22 has two output shafts, which are respectively connected to the two screws 21. The power device drives the two screws 21 to move synchronously in opposite directions.

[0023] Embodiment three: See also Figure 3 The cutting mechanism 4 is composed of a mounting frame 41, a roller 43, a belt 44, a guide rod 42, a slider 45, and a cutting knife 40. The mounting frame 41 is fixed on the frame 1. Two horizontally arranged guide rods 42 are installed on the mounting frame 41. The two guide rods 42 are parallel to each other. Two identical rollers 43 are installed on the mounting frame 41. The central axes of the two rollers 43 are located on the same horizontal plane. The central axes of the two rollers 43 are parallel. One of the rollers 43 is connected to a second motor, and the second motor drives the connected roller 43 to rotate forward and reverse periodically. The belt 44 is sleeved on the two rollers 43.

The slider 45 is fixed to the upper half or the lower half of the belt 44, and the cutting knife 40 is fixedly connected to all the sliders 45.

[0024] Working process of the present invention: During the operation of the tapioca pearl pelletizer of the present invention, the mixed starch mass is placed in the discharge bin 25, and the screw 21 continuously pushes the starch mass toward the extrusion tube 20, and finally the starch mass is extruded from the extrusion tube 20 to form starch strips. In this process, when there are too few starch masses in the discharge bin 25, new starch masses can be added or appropriately pressed down with a tool.

[0025] After leaving the extrusion tube 20, the starch strips will come into contact with the dry starch in the dry powder box 3. The starch strips will be stained with dry starch, and it is not easy for the starch strips to stick to each other. The starch strips move downward under the action of gravity. After the starch strips come into contact with the guide plate 5, they move downward along the guide plate 5. In this process, part of the dry starch will also fall directly onto the guide plate 5, which can effectively prevent the starch strips from sticking to the guide plate 5. In this process, the second motor drives the cutting knife 40 to move back and forth. The cutting knife 40 cuts the starch strips passing through the cutting knife into starch grains to form tapioca pearls. The tapioca pearls continue to roll downward along the guide plate 5 and finally roll onto the conveyor belt 6. The conveyor belt 6 transports the tapioca pearls away.

[0026] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
