Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, specifically relating to an automatic cleaning device for edible oil storage tanks. Background Technology

[0002] In the food processing industry, small edible oil storage tanks are common storage equipment. Although they are relatively small and can be cleaned manually, after long-term use, oil residues, impurities, and microorganisms will still adhere to the inner walls of the tanks and the bottom of the tank lids. If these residues are not cleaned in time, they will affect the quality of the edible oil stored subsequently, and may even breed harmful substances, posing a threat to food safety.

[0003] Currently, cleaning small edible oil storage tanks is still primarily done manually. Workers must use ladders or other tools to climb to the tank opening and reach inside with cleaning tools to wipe it clean. This manual cleaning method has several drawbacks: Firstly, it is labor-intensive and inefficient. Due to the limited space inside the tank, workers' arm movements are restricted, especially in corners and the bottom of the tank, where manual cleaning is difficult and leaves unsanitary areas. Secondly, it is inconvenient for workers to reach inside with tools, and residual oil vapors may remain inside. Although small tanks have slightly more space than large tanks, there are still certain safety risks. Furthermore, direct contact between workers and residual grease during manual cleaning may also affect their health. In addition, manual cleaning consumes considerable manpower and time, hindering efficient production for businesses. Therefore, developing a device that can automatically clean small edible oil storage tanks, improve cleaning efficiency and quality, and reduce safety hazards has become an urgent problem to be solved in the food processing equipment industry.
