Electric-frying oven temperature control circuit

Abstract

The utility model discloses a control circuit for full automatic food fryer, belonging to the electronic technical field, which solves the problems of the electric fryer in prior art that the temperature sensitivity is low and the frying time can not be automatically adjusted. The utility model is characterized in that the electric fryer temperature control circuit comprises a control center and an electric power supply for the control circuit, the control center is connected with a display circuit for displaying the working information, a temperature controller for controlling the oil temperature of the electric fryer and a temperature test and analysis circuit, the control center sends the control information to the temperature controller, the temperature test and analysis circuit checks and processes the oil temperature, the control center is also connected with an operating keyboard used for adjusting and setting the oil temperature. The temperature control circuit and the temperature controller of the electric fryer has advantages of high control sensitivity, precise control of temperature variation, real-time adjustment of the cooking time for the frying food based on that the different temperature variation caused by the different food and quantity, simple operation and high automation.

Description

technical field [0001] The invention belongs to the field of electronic technology, relates to a kind of commercial fast food such as KFC, McDonald's, beautiful kitchen and hotel utensils, in particular to a control circuit of a fully automatic food fryer. Background technique [0002] Fried food is loved by the public because of its unique taste. The existing method of frying food is usually to place a fryer on an ordinary frying stove or to use an electric fryer to make it. Its biggest shortcoming is that it cannot control the oil temperature, and the temperature of the oil can only be grasped by feeling or experience. Therefore, the fried food is easy to burn, which not only affects the color of the food, but also easily destroys the internal nutrition of the food. It is difficult to control the taste and appearance of the food in the best state. At the same time, the fryer that cannot control the temperature cannot adapt to the needs of large-scale production.

AI Technical Summary

Problems solved by technology

However, this fryer cannot set the time for frying the food, and requires a special person to keep track of the state of the fried food at all times, and cannot achieve a high degree of automation

[0005] In addition, when the fried food is put into the fryer, due to the temperature difference between the fried food itself and the frying oil, the frying oil will cause a certain temperature drop after the fried food is put in.

At the beginning of the frying process, because the initial temperature of the food is not considered to compensate, the oil temperature takes a long time to rise, resulting in low production efficiency, and there is a difference between the actual frying time and the theoretical time
