The paper used fresh pineapple that Hainan produce as raw materials,adopted explosion-puffing technology to manufacture a new type of instant pineapple chips and the major parameters including variety, different breed,syncopation,mature degree,operation temperature,pressure difference,residence time and moisture content were found through the single factor experiments.

This paper used fresh bananas as raw materials, adopted explosion-puffing technology to manufacture a new type of instant banana chips and the major parameters including variety, different mature degree, different preparation, operation temperature, pressure difference and residence time .

Quality of strawberry chips produced by explosion-puffing drying technology is effected by slice thickness, moisture content, operation temperature and pressure difference.

The effect of type, concentration, temperature of sugar solution and soaking time on quality of the apple chips produced by explosion-puffing drying technology were studied by measuring the soluble solids concentration of sugar solution.
