After the end of the endothermic reaction stage and the first explosion, the heat-proof reaction is carried out immediately. The sound produced by the expansion effect produced by the preheating of raw beans during the first burst, the sound and time of bursting will vary with the variety, density and vitality of the endothermic reaction stage. Under the condition of high temperature baking, direct fire baking will occur 1 explosion in 7 minutes, while semi-hot air.

Balance point when the roaster is fully preheated and the internal temperature of the boiler is about 200 degrees, put the prepared raw beans into the furnace. At this time, the raw bean in the furnace will begin to endothermic reaction, and the internal tissue of the raw bean will begin endothermic reaction, that is, the raw bean begins to absorb heat, absorbing all the temperature in the furnace into its own body, so the temperature in the furnace begins to drop slowly, and when the temperature inside the furnace

Equilibrium Point When the roaster is fully preheated and the internal temperature of the boiler is around 200 degrees, place the prepared green beans into the oven. At this time, the raw beans in the furnace will begin to undergo endothermic reactions, and the internal tissues of the raw beans will begin to undergo endothermic reactions, that is, the sound beans will begin to absorb heat and absorb the temperature in the furnace into their own bodies, so the temperature in the furnace will begin to slowly decrease. When the temperature inside the furnace is low, the temperature inside the furnace will begin to decrease.
