27/04/2010 Lehigh Valley, Pa. Air Products (NYSE:APD), a recognized leader in cryogenic grinding, has expanded its portfolio of size reduction offerings with the addition of an ultra-fine grinding mill. This patented mill is capable of processing materials at throughputs ranging from just a few kilograms to over 1000 kilograms per hour.
1. Cryogenic grinding, also known as freezer milling/ freezer grinding/ cryomilling is the act of cooling or chilling a material and then reducing it to smaller particle size. 2. Almost all materials embrittle when exposed to low temperature.
Cryogenic grinding of the carob pods provided the powder with smaller particles, as seen in Table 2. All fractions were significantly smaller compared to the VG-4 and VG-8 carob powders. However, the VG-4 carob powder was characterized by an almost two and a half times higher D50 value (233 µm) in comparison with CG and VG-8 carob powders (90.62 and 87.89 …
Comparative study had shown that ambient grinding need more power (8.92%) and specific energy (14.5%) than cryogenic grinding. Particle size analysis had shown that cryogenic grinding produced ...

Journal of Food Science and Technology 52 (1), 568-573., 2015. 48. 2015. Effect of cryogenic grinding on volatile and fatty oil constituents of cumin (Cuminum cyminum L.) genotypes. LK Sharma, D Agarwal, SS Rathore, SK Malhotra, SN Saxena. Journal of food science and technology 53 (6), 2827-2834., 2016.
Cryogenic grinding installations are used for gentle grinding of: Aromatic Very oily Greasy or temperature-sensitive products A cooling down of the material to below 0 oC prevents evaporation of distilled oils or the melting of heat sensitive greases.
Liquid nitrogen in the Cryo-grinding process serves two purposes; • To cool the raw material and the mill to operating temperatures • To remove the heat liberated during grinding Table 1: Properties of Cryogenic Fluids Used in Food Systems (Murthy Et Al, 2015) Properties of Cryogens LN2 CO2 Freon-12 Density (kg/m3) 784 464 1485 Boiling point (0C) -196 -78.5 …

ADVANTAGES OF CRYOGENIC GRINDING Higher material removal rate can be achieved. Tool wear and tear is minimized to a great extent. Grinding forces are reduced. Cryogens act as coolant and hence the effects of overheating of the tool and work piece are reduced. Materials which are soft and elastic in nature such as rubber can be easily machined with this process.
Pesek et al. (1985) reported that cryo grinding has high volatile oil content and volatile compound in nutmeg, cinnamon, cumin, white pepper, and …
cryogenic grinding systems. For example, the research is seeking to demonstrate that the use of liquid nitrogen in conventional cryogenic grinding systems can enhance the overall energy efficiency of the system while producing finer particles as a result. As research into this area continues to progress, cryogenic grinding is gaining rec-
