    Abstract: A photo acoustic non-destructive measurement apparatus and method for quantitatively measuring texture of a liquid. The apparatus includes a laser generating tool, an acoustic capturing device, and a data processing unit. The laser generating tool directs a laser towards a surface of a liquid contained in a container and creates pressure waves that propagate through the air and produce an acoustic signal. The acoustic capturing device records and forwards the signal to a data processing unit. The data processing unit further comprises a digital signal processing module that processes the received acoustic signal. A statistical processing module further filters the acoustic signal from the data processing unit and generates a quantitative acoustic model for texture attributes such as hardness and fracturability. The quantitative model is correlated with a qualitative texture measurement from a descriptive expert panel. Textures of liquids are quantitatively measured with the quantitative acoustic model.

    Abstract: There is provided a double-compression, pneumatic-driven popping apparatus for making chip-like snack foods. The apparatus includes a first and second popping machine sections, each having a pneumatic-driven compression cylinder; and a mold plate coupled to the pneumatic cylinder and responsive to urging of the first pneumatic cylinder. A ring mold is located between the first and second machine sections and is subjected to compression by the first mold plate and the second mold plate. The apparatus has a pneumatic drive system including a compressed gas vessel, and a controller configured to control the pneumatic-driven compression cylinders independently through fast-acting control valves. During use, the apparatus applies pneumatic double-compression in a controlled manner such that a time interval between the first and the second compression steps is in the range of milliseconds, to produce a chip-like snack food product.
