Problems solved by technology

However, the thermal conductivity of food waste and gas is extremely poor, so the heating effect of this heating mode on food waste is extremely uneven, and the heating efficiency is also extremely low; and the relative position between the heating wire and the temperature sensor has a great influence on the heating effect. The impact is also great. If the temperature sensor collects the temperature data of the air in the warehouse, due to the extremely poor thermal conductivity of the gas, when the temperature sensor senses that the temperature has risen to the set value, the food waste has been overheated and coked, and the decomposition bacteria will It will be killed by overheating, and if the temperature sensor collects the temperature of the warehouse wall, then when the temperature sensor senses that the temperature has risen to the set value, the heat has not been transferred to the food waste, so the heating effect is also very poor; in addition , due to the uncontrollable heat conduction direction of the material, it will transfer heat to its surroundings with the same thermal conductivity, thus causing a great waste of energy
It can be seen from the above that the heating effect of the existing working mode is extremely unreasonable, resulting in extremely poor fermentation and decomposition effects and efficiency of food waste, and energy waste is also serious

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a kitchen garbage fermentation heating system and a control method thereof. Background technique [0002] At present, domestic food waste fermentation bins are heated by electric heating wires, and the temperature sensor collects the temperature of the air in the bin or the temperature of the bin wall. The principle of this heating mode is that the heating wire emits heat, and then the heat is transferred to the bin wall. , the warehouse wall then transfers the heat to the food waste in contact with the other side, the food waste on the contact surface then transfers the heat to the food waste inside, or the gas in the gap between the food waste, and the gas transfers the heat to the other side contact with food waste. However, the thermal conductivity of food waste and gas is extremely poor, so the heating effect of this heating mode on food waste is extremely uneven,...
