Fryer

Abstract

The invention provides a fryer, of which, on standby for cooking, the temperature of cooking oil is kept at a level slightly lower than that in cooking, and in cooking, the temperature can be quickly raised to a cooking temperature and where heat exchange of the cooking oil is easily performed to prevent deterioration of the cooking oil. The fryer can achieve an excellent cooking environment and enhance work efficiency. The fryer has a storage tank, a heater and a filtering water tank, wherein the storage tank stores an oil layer and a water layer for cooking into two layers; the filtering water tank is used for guiding the water in the water layer to filter by the filter and returning the water to the storage tank; the filtering water tank is provided with an impurity removing device for connecting a water drainage path and a water supplying path; the water drainage path exhausts the water having impurity from the upper stream of the filter to the external part of the filtering water tank; the water supplying water tank is provided with a flow regulator for supplying the water to the upper stream side or the lower stream side when exhausting the water.

Description

[0001] The patent application for the present invention is a divisional application of the patent application for invention with the filing date being April 3, 2007, the application number being 200780000814.3, and the invention name being "fryer". technical field [0002] The present invention relates to a deep fryer that automatically recovers oil residues and the like, automatically cleans cooking oil, maintains the transparency of the cooking oil, prevents the deterioration of the cooking oil, and maintains the cooking oil for a long period of time. Background technique [0003] In a conventional fryer, water and cooking oil are stored in two layers in order from the bottom inside the storage tank, and the water and cooking oil are stored so that their mutual boundaries are close to each other, and they are arranged in the oil layer. The heater can heat the cooking oil to a predetermined temperature (Patent Documents 1 to 3). [0004] In such a frying machine, fine oil r...

Problems solved by technology

However, there is no device that can properly eliminate air bubbles, and it is expected to have such a fryer with the function of eliminating air bubbles.

[0015] Furthermore, in such an existing frying machine, in order to remove the foreign matter left in the water layer, it is necessary to open the faucet arranged at the lower part of the water layer to release water, and re-inject fresh water into the water layer to reproduce a clean water layer with a specified amount of water.

[0016] Moreover, when the frying machine is provided with the water tank of filtered water outside the storage tank and adopts the circulating filtration method, in order to remove the foreign matter retained in the filtered water tank, it is necessary to manually remove the foreign matter and clean the filtered water tank when cooking is not carried out, which costs a lot of money. Time, long cooking interruption time, resulting in the consequences of reduced cooking efficiency
