[0039] The food filling and batching system mainly consists of two parts: the filling subsystem and the batching subsystem. It aims to achieve efficient and accurate filling of powdered dietary foods and solve the problems caused by traditional mixing methods.

[0040] The filling subsystem uses the existing technology, including a feeding port 1, a hopper 2 and an injection head 3. The bulk of the pre-mixed powdered food raw materials is added to the hopper 2 through the feeding port 1, and then the bulk of the powdered food raw materials is injected into the filling container 4 by the injection head 3.

[0042] Working principle of food filling and batching system:

[0043] Mixing of powdered food materials: Different powdered food materials are transported through their respective powder conveying components 7. Under the action of the powder conveying component 7, the powdered food materials enter the mixing chamber 5 through the feeding channel 7e3 and are fully mixed in the mixing chamber 5.

[0044] Powder conveying: The mixed powdered food raw materials are conveyed to the hopper 2 of the filling subsystem through the main connecting pipeline 6 under the action of the pressure gas source 10. The bulk powdered food raw materials in the hopper 2 are injected into the filling container 4 through the injection head 3.

[0046] Through the mixing chamber 5 of the batching subsystem, different raw material powders can be fully mixed, avoiding the unevenness problem caused by direct stirring in the hopper, and ensuring the accuracy of the product formula.

[0047] The batching subsystem adopts a modular design, and key components such as the powder conveying component 7 and the mixing chamber 5 are easy to disassemble and clean, reducing the difficulty and time of cleaning.

[0048] Compared with the solution with built-in stirring mechanism, this system has lower equipment complexity, lower cost and easier maintenance.

[0049] The batching subsystem and the filling subsystem are independent of each other and can work in parallel, thus improving production efficiency.

[0050] This food filling and batching system achieves efficient and accurate filling of powdered dietary foods by introducing a batching subsystem, effectively solving the problems caused by traditional mixing methods.
