Working principle of Hot Air Puffed Rice Popper Machine
Working principle:
Will certain materials into with cover sealing in the cast steel tanks, use liquefied petroleum gas, gas or coal to heat, and constantly rotating tanks at a certain speed, uniform heat of material, along with the continuous heating, tank temperature rise gradually, reaches above 100 ℃, material surface moisture in the body will escape and vaporization, certain pressure in the tank. When the material moisture is controlled about 5% ~ 8%, the internal pressure of the tank will reach 0.8-1.25 Mpa (different material pressure). Has basic cure, material of the tank at this time if the tank lid suddenly opened and released by high temperature and high pressure condition suddenly dropped to atmospheric pressure, the material of puff wheat puffing machine will be in the position of the water loss by air filled but bigger, its structure changes, raw starch starch (beta) become mature (alpha starch), volume) several times to ten times. At the moment of release, the airflow and materials of the extruder are immediately expanded and the air is sharply torn apart, producing a loud noise that reaches around 100 decibels.
The air flow puffed wheat making machine is now mainly used for food manufacturers to produce rice, wheat, rice sugar, sweet and crisp coffee corn, bean powder, buckwheat flour, bitter buckwheat tea and other leisure food production.
