Description

Technical Field

[0001] The utility model belongs to the technical field of food processing and relates to an oil injection monitoring device based on visual imaging. Background Art

[0002] Currently, in the process of puffed food processing, in order to ensure the puffing of the puffed food, it is necessary to spray oil on the surface of the puffed food raw materials, and the food raw materials after oil spraying are puffed under high temperature.

[0003] A search revealed a document with publication number "CN214156183U" that discloses a food oil spraying device comprising a first oil spraying pipe, a second oil spraying pipe, a third oil spraying pipe, an air inlet pipe, an oil spraying pipe air inlet connector, a manifold, and a nozzle. One end of the nozzle is fixedly connected to a high-pressure air pipe. In this food oil spraying device, oil flows from an oil tank through an inlet nozzle into the inlet nozzle connecting pipe, where it is compressed by the high-pressure gas and atomized into a mist. Two or three nozzles are installed in each of the first, second, and third oil spraying pipes, ensuring that the oil pressure at each nozzle is similar, thus avoiding the phenomenon of oil pressure decreasing with distance from the oil inlet on the same oil spraying pipe.

[0004] The above-mentioned oil spraying device effectively solves the problem of oil pressure of oil spraying. However, when it is used in the process of oil spraying of puffed food, we found that the oil spraying condition was not tested. When the amount of oil on the surface of the food raw material is too little, it will affect the puffing of the food, thereby affecting the processing of the food. Summary of the Invention
