Factors Affecting Rice Milling Quality FSA2164

Milling Quality . Several factors during rice production can affect milling quality. Such factors are generally manifested as individual kernel strength reduction, which withstand the rigors of hulling and bran removal without breaking apart. Diseases such as rice blast or sheath blight can cause milling quality reductions (Candole et al., 2000).

Cryogenic Grinding Seminar Topics fo

Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens.

Cryogenic Milling of Titanium Powder

Cryogenic milling leads to the reduction of powder crystallite size to the order of tens of nanometers for aluminium [7] and for titanium and its alloys [15,17,18]. At the same time, the diffusivity of possible contaminating elements such as N or O is significantly reduced [17].
