There are averaged four-hundred thousand tons public food are collected and stored each year in Taiwan, and majority of public food are taken and stored at more than 300 farmers' associations or commissioned non-governmental public food warehouses. The storage period will be from one to three years. Since the mass storage of the rice and implementing the actual quality inspection for public food, a device with multiple sampling tubes which can take the samples from different layers using the way of the up-down pull-take. Each section of sampling tubes at different depths can obtain the samples for the quality inspection basis by the Agriculture and Food Agency (AFA), Council of Agriculture, Executive Yuan. However, applying sampling tubes for sampling the heap of rice, the deeper distance in the heap of rice will result in the greater resistance which cannot be afforded by human. Thus a pneumatic propulsion system has been developed to pull the sampling tube into the deeper layer of the packed rice heaps using the pneumatic power. For the on-site rice warehouse testing, the actual resistance of the sampling tubes in the rice heaps has been measured to prove it can reach the six-meter depth for rice sampling. The standard operation procedure has also been established for the pneumatic propulsion system.
