Grain puffing machine is used to puff corn, wheat, barley, rice, sorghum, and other grain machinery. By continuously heating the puffing tank, the moisture of the material in the tank is continuously evaporated, and the puffing effect is produced under the action of pressure.

Structure and composition of grain puffing machine:
The cereal puffing machine is composed of a puffing tank body, a heating device, a rotating device, a safety protection device, a vibration-damping device, a frame, a base and the like. This machine is based on the traditional puffing machine and is technically transformed. The output is 3-4 times that of the traditional puffing machine, and the safety factor is also greatly improved.
Working principle of grain puffing machine:
A proper amount of material is put into a sealed expansion tank with a cover, heated by liquefied gas, natural gas, coal or gas, and rotated continuously at a certain speed to make the material uniformly heated. With continuous heating, the temperature inside the tank gradually increases. When it reaches 100℃ or above, the surface and internal moisture of the material will escape and vaporize, and a certain pressure is formed in the tank. When the moisture content of the material is evaporated about 5%-8%, the pressure in the tank will reach 0.8-1.25 Mpa (the pressure of different materials is different).
At this time, the material has basically matured in the tank. If the lid of the tank is suddenly opened, the material is suddenly released from high temperature and high pressure to normal temperature and pressure. The space of water loss inside the material will be rapidly enlarged by air filling, and its structure will change. Raw starch (beta-starch) becomes mature starch (alpha-starch), and its volume will expand a few times. More than ten times. At the moment of release, the material will be ejected from the outlet, and at the same time a loud noise will be produced, and the sound will reach about 100 decibels.
Technical parameters of the cereal puffing machine:
- Power supply：single-phase220V
- Power capacity：75KW
- Curb weight：450kg
- External dimension：1650×800×1350MM
Characteristics of the grain puffing machine:
- Large output. It can puff 10 kg of rice at a time, 8-9 kg of corn, and 8-10 kg of wheat.
- Scope of application: rice, corn, wheat, barley, sorghum, soybeans, and other grains.
- Labor-saving, energy saving: A skilled worker can control three machines at the same time, which greatly saves human resources. In addition, this machine uses advanced technology, which can save about 20%-30% energy than other machines.
- Double stoves take less time to heat up: Puffed corn takes only 6 minutes at a time.
- Operation safety and convenience: Four safety insurance, humanized design, reduce labor intensity, easy operation of workers.
- Convenient discharge: The grain puffing machine can automatically tilt 35 degrees and eject material in the direction of receiving.
- Low noise: The machine is equipped with a silencer, and the puffing sound is smaller.
How to make puffed rice cereal?
1. First, prepare fresh rice. Do not use heat, yellow, and deteriorate rice.
2. When the first time to use the grain puffing machine, the empty pot should be heated up to 120 ℃, then shut down. Loading raw material, blending with 50g edible talcum powder. (The raw material have to follow the request: no miscellaneous things, no broken pieces, and contained water rate ≤15%)
3. According to the operation procedure strictly to carry on produce: Loading procedure: loading material →covered →tighten the cover →switch on →the heating.
In the process of heating, switch on tumbler switch every 3~4 minute once, change direction and make material heating more even. adjust the thermodynamic power smaller 1/2 at 2~3 minutes before discharge.
4. Discharge procedure: pull the buffer bracket under the pot→switch off →shut down →lock tight →fire off.
Discharge procedures are very important, do not make a mistake.
