STEP : 3 CONTAINER MAKING
After cutting these cardboard sheet we make container for bottle seating. Use the glue gun to stick cardboard. Join all the cutting piece like shown in above picture, and make container.
STEP : 4 THARMOCOLE BOX
Make open square box from tharmocole sheet using glue gun, insert it in cardboard containers. These tharmocole box help to minimize the heat transfer. So ice-cream can not melt very fast.
STEP : 5 AIR PUMP
In this project main heart is the air pump. Air pump insert the air inside the bottle and pressure is increase at the surface of ice-cream, so ice-cream come upward through pipe.
STEP : 6 CONNECTION DIAGRAM
Connect the air pump with battery and switch by soldering iron as per above picture.
STEP : 7 FINAL ARRANGEMENT
Drill two hole in bottle cap for inserting different size pipe.
Join the small size pipe with air pump and insert in cap, that must be above the ice-cream level. Than insert bigger size of pipe one end in the ice-cream level and other end at our output side.
