Description

Technical Field

[0001] This application relates to the field of edible oil filtration technology, and more specifically, to a multi-stage edible oil filtration device. Background Technology

[0002] Edible oil refers to oils extracted from plant seeds, fruits, or animal fat tissues, which are refined and used for cooking, seasoning, or direct consumption by humans. During the production, processing, and use of edible oils in the catering industry, various impurities inevitably mix in, such as food residues, carbon compounds, colloids, moisture, and suspended particles. These impurities not only affect the color, odor, and taste of the oil, but also accelerate its oxidative rancidity and reduce its thermal stability. Therefore, filtration of edible oil is a crucial step in the production process. With the continuous improvement of people's health awareness and the increasingly stringent food safety standards, the purity and safety of edible oils have received widespread attention.

[0003] To improve the cleanliness of edible oil, filtration devices are usually used for purification. Commonly used edible oil filtration equipment is mostly single or multi-layer filter screen or simple filter bag structure. Since most filtration equipment has a fixed structure, impurities are prone to accumulate and filter screens become clogged after long-term use. This not only reduces filtration performance but may also become a source of secondary pollution, affecting the hygienic quality of edible oil. At the same time, the inconvenience of cleaning and maintaining the equipment increases the cost of use and the difficulty of operation, making it difficult to meet the needs of the food processing and catering industries for efficient, safe and easy-to-maintain filtration equipment. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a multi-stage edible oil filtration device, which aims to improve the problem that the inconvenience of cleaning and maintenance of filtration equipment increases the cost of use and the difficulty of operation, making it difficult to meet the needs of the food processing and catering industries for efficient, safe and easy-to-maintain filtration equipment.

[0005] This application provides a multi-stage edible oil filtration device, including a main structure and a filtration structure.

The output end of the temperature sensor is connected to the input end of the control panel, and the output end of the control panel is connected to the input end of the heating tube.

[0011] In the above process, after the device is connected to the power supply of the external equipment, the temperature sensor will detect the oil temperature inside the preheating tank and transmit the detection result to the control panel in the form of an electrical signal. The control panel controls the opening and closing of the heating tube according to the feedback signal, thereby maintaining the oil temperature inside the preheating tank within a certain range. By heating the oil, the fluidity of the edible oil during the filtration process can be improved, and the filtration efficiency can be accelerated.

[0012] In one specific implementation, the first filter assembly includes a first fixing ring and a first support frame. The first fixing ring is fixedly connected to the upper end of the inner cavity of the filter tank, and the first support frame is detachably connected to the inner cavity of the first fixing ring.

At the same time, the number of filter screen bodies can be increased as needed, as long as the support of the added filter screen body is smaller than the inner diameter of the upper support.

[0018] Compared with the prior art, the beneficial effects of this application are as follows: by using filter screens with different mesh sizes to filter edible oil in stages, the filtration effect of impurities can be effectively improved.
