Description

Technical Field

[0001] This utility model relates to the technical field of dairy processing equipment, and in particular to a filling equipment for fermented milk production. Background Technology

[0002] In the actual use of dairy fermentation tanks, high-viscosity dairy products are very easy to solidify and adhere to the inner wall of the tank, which makes it difficult to clean the filling equipment. In addition, solid fruit particles or grains may be added during the filling process, which can cause blockages, resulting in low filling efficiency and accuracy, as well as material residue.

[0003] Chinese utility model patent CN221203971U (publication date: June 25, 2024) discloses a dairy fermentation tank. This patent adjusts the positions of multiple stirring blades to ensure they adhere to the inner wall of the fermentation tank, effectively cleaning solidified dairy products adhering to the tank wall and reducing the difficulty of cleaning the tank's inner wall. By guiding and restricting the movement of the stirring blades, the adhesion between the blades and the tank wall is improved, allowing the dairy products to fully blend. Chinese utility model patent CN203789026U (publication date: August 27, 2014) discloses a device that improves sterilized milk filling equipment to produce room-temperature fermented milk. This device effectively avoids the problem of easy spoilage due to bacterial contamination from contact with surrounding air during the filling process of ordinary bowl-type yogurt production lines. While the above patents address the difficulty of cleaning existing fermented milk filling equipment to some extent, they do not consider the problems of easy clogging of the filling equipment and low filling accuracy and efficiency. Utility Model Content

[0004] This application provides a filling equipment for fermented milk production, which mainly solves the problems of easy clogging, low filling accuracy and efficiency, and complex equipment maintenance in existing filling equipment. The specific technical solution is described below.

[0005] A filling device for fermented milk production includes a storage tank, a feeding system, a discharging system, a drive system, a transfer tank, and a workbench. The feeding system is installed on the storage tank, the bottom of the storage tank is connected to the transfer tank, both sides of the transfer tank are connected to the discharging system, and the drive system and the transfer tank are both installed on the workbench. The drive system is connected to the transfer tank and the discharging system.

[0006] Furthermore, the feeding system includes a main channel, an auxiliary channel, and a solid material addition port; the auxiliary channel is annular and located outside the main channel; the bottom of the main channel is connected to a storage tank via a storage valve; the main channel is used to transport viscous fermented milk, and the auxiliary channel is used to transport cleaning liquid, compressed air, or sterile inert gas. In the initial state, the auxiliary channel is connected to external compressed air or sterile inert gas.

[0007] Furthermore, the solid material addition port is located on the outside of the storage tank near the transfer tank, which facilitates the replacement of solid materials with different flavors.

[0008] Furthermore, the drive system includes a drive motor, a first drive rod, a second drive rod, and a roller; the drive motor is mounted on the workbench, one end of the first drive rod is connected to the drive motor, and the other end is movably connected to the second drive rod via the roller, and the other end of the second drive rod is movably connected to the transfer tank.

[0009] Furthermore, the end of the first drive rod connected to the drive motor is retractable.

[0010] Furthermore, the transfer tank is a horizontally placed cylinder, and one end of the transfer tank is provided with a cylindrical protrusion for connecting the second drive rod. The diameter of the cylindrical protrusion is smaller than that of the transfer tank.

[0011] Furthermore, the discharge system includes a discharge pipe, a conveying pipe, and a discharge port. One end of the discharge pipe is connected to the transfer tank, and the other end is connected to the drive motor. A push rod is provided inside the discharge pipe near the drive motor. One end of the conveying pipe is connected to the transfer tank, and the other end is connected to the discharge port.

[0012] Furthermore, the transfer tank is provided with a through hole inside, which is used to connect the transfer tank with the discharge pipe and the discharge pipe with the conveying pipe, thereby realizing material transfer.

[0013] Furthermore, the discharge port is gradually widening and has an anti-drip ring inside to further reduce material residue.

[0014] Furthermore, the filling equipment also includes a control system, which includes a pressure sensor or has a preset program. During equipment use, when filling is interrupted or the pressure sensor detects an abnormally high pressure signal indicating a potential risk of blockage, the preset program automatically opens several holes on the main channel to initiate a brief, high-pressure pulsed backflushing. This uses airflow to flush away blockages accumulated at the feed system valve, storage valve, and solid material addition port, preventing blockage formation.

[0015] Furthermore, the discharge pipe is movably connected to the transfer tank and the drive motor, and is equipped with a scale; when using the equipment, the drive motor controls the stroke and speed of the push rod to achieve high-precision and repeatable quantitative filling of viscous materials.

[0054] Example 3

[0055] Based on Embodiment 1 or 2 above, this embodiment introduces a method for using a filling equipment for fermented milk production, including:

[0056] Step S1: Open the valve of the main channel 21 to deliver the fermented milk;
