Description
Technical Field
[0001] This invention belongs to the technical field of food processing equipment, specifically relating to an automatic liquid seasoning addition system and method for a stir-fry machine. Background Technology
[0002] Existing automatic cooking machines have significant technical defects in the liquid seasoning addition process: First, the supply of liquid seasonings (such as oil, salt water, soy sauce, cooking wine, etc.) relies on multiple water pumps driven independently. The operation of multiple pumps can easily lead to uneven pressure, thus affecting the accuracy of seasoning measurement. At the same time, the heat generated by the water pumps can damage the original quality of the seasonings, and the redundancy of the equipment increases the probability of failure and reduces the stability of system operation. Second, the addition of water and seasonings in traditional cooking machines relies entirely on the operator's experience and judgment. The timing and amount of addition lack standardized control, resulting in inconsistent product quality and making it impossible to achieve stable mass production. In addition, existing addition systems are usually only compatible with a single cooking machine, making it difficult to meet the large-scale production needs of multiple machines operating in parallel, and their versatility and scalability are poor.
[0003] In view of the shortcomings of the existing technologies, there is an urgent need for an automatic liquid seasoning addition system and method that can achieve stable pressure, accurate metering, no damage to the quality of seasonings, and adaptability to multiple operation scenarios. Summary of the Invention
[0004] To address the problems of uneven pressure, inaccurate metering, susceptibility to condiment quality, high risk of failure, unstable output, and poor adaptability in existing automatic cooking machine condiment addition systems, this solution provides an automatic liquid condiment addition system and method that features constant pressure, accurate metering, protection of condiment quality, low risk of failure, stable output, and flexible adaptability to single or multiple cooking machines.
[0005] The technical solution adopted in this invention is as follows: An automatic liquid seasoning addition system for a stir-fry machine includes: At least one condiment container is located inside or above the cabinet, which is used to install the cooking machine; The pneumatic pressurization system includes a booster pump and an air filter. The air filter is located at the outlet of the booster pump, and the outlet of the air filter is connected to all the condiment containers through an air pipe to achieve pressurization of all the condiment containers by the same booster pump. The piping system includes seasoning pipes, water pipes, and a feeding head. The feeding head is located in the main body of the cooking machine within the cabinet and has multiple feeding ports. The water pipes and seasoning pipes are connected to different feeding ports, and the seasoning pipes are connected to corresponding seasoning containers. A solenoid valve is installed on the pipe connected to the feeding head. When the solenoid valve is opened, the liquid seasoning in the seasoning pipe or the water in the water pipe flows to the feeding head and is sprayed into the main body of the cooking machine. The number of seasoning pipes, seasoning containers, and feeding ports is the same as the number of types of liquid seasonings, and a solenoid valve is installed on each seasoning pipe. The control module is connected to the booster pump to control its start and stop actions, and is also connected to each solenoid valve to control their opening and closing actions.
[0006] Optional: The cabinet has multiple cooking machine bodies, each with a feeding head on top; a tee is installed on the seasoning pipe and the tap water pipe to divert the flow to different feeding heads.

[0012] Optionally, the cabinet is equipped with a cable tray for routing condiment pipes, water pipes, electrical wires, and gas pipes. The cable tray includes an insulation tray and an insulation tray cover. The insulation tray is U-shaped, and the insulation tray cover covers the opening of the insulation tray. When the condiment container is connected to the pneumatic pressurization system, the condiment container is a pressure vessel. The condiment container installed on top of the cabinet is used to hold thick liquid seasonings.
[0013] Optionally, a common fume hood is installed above all the cooking machines, and the outlet of the fume hood is connected to the exhaust fan.
[0014] An automatic liquid seasoning addition method for a cooking machine, using the aforementioned automatic seasoning addition system; the addition method includes the following sub-methods: S1: Liquid seasoning filling method: Close the liquid outlet valve and air inlet valve of the seasoning container, and open the exhaust valve to release the residual pressure in the seasoning container; open the feeding valve, and add the corresponding liquid seasoning into the seasoning container through the feeding funnel. After the filling amount reaches 80% of the container volume, close the exhaust valve and feeding funnel, and open the liquid outlet valve and air inlet valve. The seasoning container enters the standby state; when multiple seasoning containers are placed side by side, repeat the above operation S1 to complete the addition of different seasonings. S2: Air pressure boosting and seasoning delivery method: The booster air pump is started through the control module, and the solenoid valve on the air pressure system is opened, so that the air is delivered to each seasoning container after being purified by the air filter, so as to realize the synchronous and uniform pressurization of all seasoning containers; when the pressure in the seasoning container is greater than the preset maximum threshold, the booster air pump stops working; when the pressure in the seasoning container is less than the preset minimum threshold, the booster air pump starts to ensure the pressure balance in the seasoning container. During the cooking process of the cooking machine, the control module opens the corresponding solenoid valve at the feeding head according to the preset time point, so that the liquid seasoning is sent into the main body of the cooking machine through the seasoning pipe under air pressure; when multiple seasoning containers are in parallel, the above operation S2 is repeated to complete the addition of different seasonings. S3: Tap water delivery method: When water needs to be added to the main body of the cooking machine, the solenoid valve on the tap water pipe is opened through the control module, and the tap water is delivered to the main body of the cooking machine through the corresponding feeding port under its own pressure.
[0015] S4: Parallel operation method of multiple cooking machines: When multiple cooking machines need to operate at the same time, the liquid seasoning pipes, tap water pipes, gas pipes and circuits of the cooking machines are interconnected. The control module controls the opening and closing of the solenoid valves on each pipe to achieve independent addition of liquid seasonings for multiple cooking machines.
[0016] The beneficial effects of this invention are as follows: 1. This solution uses the same air pressure pressurization system to supply pressure to multiple seasoning containers, which makes the air pressure more uniform and solves the problem of insufficient metering accuracy in the traditional method of extracting liquid seasonings with multiple water pumps, thus significantly reducing the error in the amount of liquid seasoning added. 2. In this solution, the booster pump of the air pressure system is connected to the condiment container remotely via an air pipe, so that the liquid condiments do not come into contact with the heating components. This avoids the damage to the quality of condiments (especially cooking oil) caused by the heat generated by traditional water pumps, and preserves the original flavor of the dishes.
