Description

  The present invention relates to an edible oil filtration device.

  In general, a fryer is used as a cooking utensil in a kitchen such as a restaurant, a restaurant, or a side dish shop. Edible oils used in fryer gradually become deep-fried and discolored and cannot be used as they are. Therefore, it has been proposed to provide an edible oil filter, filter the edible oil used in the fryer into the edible oil filter, and return the filtered edible oil to the fryer for reuse. (For example, refer to Patent Document 1).

  The edible oil filtering device includes a tank for storing edible oil used in a fryer, a filter as a filtering means provided in the tank, and a circulation pump for returning the filtered edible oil from the tank to the fryer. .

  In kitchens, the cooker is often provided with the minimum space necessary for the work to be performed, and there is not enough room for the cooking equipment on the kitchen floor. In an edible oil filtration apparatus used in such a kitchen, compact shape and good workability in a narrow space are required. For this reason, if an edible oil filtration apparatus can be arrange | positioned in the space under a fryer, an edible oil filtration apparatus will not occupy a part of space of a kitchen. However, the flyer is designed to maximize the amount of edible oil used in the flyer, so the space under the flyer is relatively small and is usually required to drain edible oil from the flyer It is the last size for an oil reservoir. Therefore, it is difficult to arrange the entire edible oil filtering device in the space below the fryer.

  Under such circumstances, it is conceivable to make effective use of the space by making the edible oil filtration device into a divided structure and reducing the size of each divided unit. For example, an edible oil filter is divided into a tank unit including a tank and a filter and a pump unit including a circulation pump, and the tank unit is disposed in a space below the fryer and is discharged from the fryer. The pump unit is arranged in a region outside the fryer.

  Such an edible oil filtration apparatus is suitable for repeatedly filtering the edible oil used in the fryer and using it. However, when the edible oil filter is not used, the pump unit occupies a part of the kitchen space, and there is a problem that the usable space of the kitchen is narrowed.
