Air puffing machine / popcorn rice wheat bulking machine

Air puffing machine is to produce puffed food, adopting gas heating, and the raw material can be soybean, corn, rice, wheat and all kinds of nuts. It bears high output, low energy consumption and high working efficiency. In addition, we conduct rigorous testing before delivering the machine.

How to operate air puffing machine?

1. Before working, operator should lubricate driving part and check whether be operating component is loose or not.

2. During the first puffing, the popcorn bulking machine should be heated to 120 ° C and then shut down. The raw material can mixed with 50g edible talc. Note: The requirements of raw material: no debris, and moisture content is less than 15%

3. loading procedure: loading → cover → tighten the lid →heating

4. Loading: Loosen the handle outward-turn the hand wheel to make the bottle turn up 45°-pour the material-close the lid-reset the hand wheel- lock it to heat.

5. During the heating process, turn on the drum switch every 3~4 minutes to change the direction to make the material heating more evenly.

6. According to the difference of raw material, you shall choose fire extinguishing with appropriate pressure (normally 8kg rice, 10kg corn). What’s more, to reach best puffing effect, the fire time is also different.

How to discharge the puffed food?

1. Pull the buffer bracket under the pot.

2.close and lock the gas to turn off the fire.

3. The operator must stand on the right side of the machine, using a special wrench to move the handle.

4. Remove excess residue from the pot after operation.

Note: Discharge procedures are very important, and operator should pay attention to it.

The precautions of air puffing machine

1. If the cover can not be tightened, the seal must be replaced.

  1. There bulking machine must be fitted with a reference ground conductor to prevent leakage.
  2. When a liquefied gas pipe leak is detected, the machine must be stopped and the main valve should be closed after the inspection.
  3. When the wheat bulking machine is working, people cannot stand in front of it.
  4. During operation, there is much noise, and it is necessary to soundproof.
  5. In normal production, the rotary bearing needs to be lubricated once (heat resistant 500 ° C).

Method: use oil gun to press some grease into the feeding cup, and add a small amount of lubricant to each rotating part
