Normally bast fibres were removed from pineapple web by wrapping the boiled pineapple leaf with nylon web and stamp on it. If using this method it will take 24 hours to stamp on 40 kilograms of boiled leaf in order to obtain clean pineapple web that is suitable for producing paper. Apart from that when pressing the fiber we need to get rid of the water as much as we can because the fiber will be weight before using to produce paper. If the water pressed out each time is not equal there may be an error about paper thickness. Moreover stamping on boiled leaf may be dangerous because the chemical substance used when boiling the leaf may burn the feet and cause wound. Currently there is a Pressing machine to separate water from pineapple fiber Rachadasak Supengcum 2010 to fix the problems mentioned above. However there is a weak point because the pressing tube is small so it can press only 1 kilogram of leaf per one time. Therefore the new machine is designed to have a pressing tube sized 30 centimeters wide and 30 centimeters long. The pressing period is 30 centimeters and the pressure for pressing is 70 bars. It takes 1 minute 15 second for one squeeze which contains 6 kilograms of pineapple leaf. It can decrease the time for pressing from the old machine by 6 times. In addition the machine is designed to have the open-close channel to bring the pressed fiber out from the machine more easily. According to the experiment to remove the bast fibres from pineapple web the most appropriate amount for each pressing is 6 kilograms. The pressing process takes 1 minute 15 second. The remaining pineapple web after the pressing is 3 kilograms

Research this project invents for design and build a cooking oven Machine to press coconut oil to work continuous and were to create and efficiency validation of Machine for built. Start to scrape continuous bring it to cooking oven set 60 ํC. use cooking oven mean 20 minute per coconut 2 kilograms open it to Machine to press coconut oil to product to work continuous. The result of design and build a cooking oven Machine to press coconut oil to work continuous. There are tools product coconut oil to work continuous 24 hours. By ratio 4 liter per hour.

This research report of the Aluminum Can Recycle Machine Project is contrived the experiments at Rajamangala University of Technology Phra Nakhon by the hydraulic pressure. Nowadays the cans make by luminum material very useful in several liquid packaging industries. When people consumed the liquid inside the cans then the cans are worthless. But the cans can be recycling from the waste material. Although we have to reduce the waste materials to follow our world as improvement. From the reasons that we mentioned we decided to start the Aluminum Can Recycle Machine research project to keep him or her eager to put the cans to the machine for consumer then encourage them by giving something back such as a candy or a rubber etc. The system working by a PLC it controls the hydraulic pressure receives the sensor signals and displays status via the 7-segment panel. The machine accepts the standard beer can and the soda can for 10 cans a time in a slot when consumer put the cans into the can receiver block the machine gives a candy back to a consumer. After a receiver-block has the 40 cans inside the machine pressing the cans at once then releasing it to collector block.
