Red date baking method without producing cancerogenic substances

Abstract

The invention discloses a red date baking method without producing cancerogenic substances. The method comprises the following steps: 1, starting a whole red date baking machine; 2, performing automatic feeding control, namely opening a feeding valve by a controller, and automatically closing the feeding valve to complete feeding by the controller when the material level of red dates reaches an infrared transmitter and an infrared receiver; 3, starting heating, namely acquiring a current temperature of a baking chamber in real time by the controller by virtue of a temperature sensor in the baking process, comparing the current temperature with a first threshold value and a second threshold value in real time when the current temperature preliminarily reaches the first threshold value, closing an air ducting device when the current temperature is higher than the first threshold value and the temperature of the baking chamber is rising, and opening the air ducting device when the current temperature is lower than the second threshold value and the temperature of the baking chamber is dropping; and 4, stopping heating, namely only closing the air ducting device and the temperature sensor by the controller when baking is ended, starting a timer, and enabling the timer to automatically perform zero clearing and start timing, wherein a time threshold value is preset on the timing module, the timer transfers a closure signal to the controller when the time of the timer is higher than the time threshold value, the controller is closed, a driving motor and the timer are simultaneously closed, and the red date baking machine stops working.

Description

technical field [0001] The invention relates to the technical field of roasting equipment, and more specifically, the invention relates to a method for roasting red dates without generating carcinogens. Background technique [0002] At present, the existing red date roasting equipment generally includes a roasting chamber and an air guide device located in the roasting chamber. The air guide device will generate circulating hot air to roast the red dates in the roasting chamber. The roasting temperature is controlled by the controller. When the temperature reaches the upper limit, the controller will close the air guide device, and when the temperature reaches the lower limit, the controller will open the air guide device to control the temperature in the baking cavity between the upper limit and the lower limit. time, to prevent the temperature from being too high and exceeding the upper limit to cause cancer. Roasted red dates are very likely to produce carcinogens; in ad...

Problems solved by technology

[0002] At present, the existing red date roasting equipment generally includes a roasting chamber and an air guide device located in the roasting chamber. The air guide device will generate circulating hot air to roast the red dates in the roasting chamber. The roasting temperature is controlled by the controller. When the temperature reaches the upper limit, the controller will close the air guide device, and when the temperature reaches the lower limit, the controller will open the air guide device to control the temperature in the baking cavity between the upper limit and the lower limit. time, to prevent the temperature from being too high and exceeding the upper limit to cause cancer. Roasted red dates are very likely to produce carcinogens; in addition, because materials often accumulate in a certain area in the baking cavity, the baking efficiency of the existing red date baking equipment is not very high, and it needs to be solved urgently
