The oxygen content of W-Y 2 O 3 composite powders prepared by balling milling and freeze-drying are 2.32% and 2.26%, respectively. After excluding the oxygen in Y 2 O 3 phase, the net oxygen (oxygen impurity) content of these two powders is 1.90% and 1.84%, respectively. Oxygen impurities usually form a thin layer of tungsten oxide on the surface of W …
Drying is among the most important processes and the most energy-consuming techniques in the food industry. Dried food has many applications and extended shelf life. Unlike the majority of conventional drying methods, lyophilization, also known as freeze-drying (FD), involves freezing the food, usually under low pressure, and removing water by ice sublimation.
Stages of Freeze Drying. There are three stages in the lyophilization process: Pre-freezing, primary drying, and secondary drying. Pre-freezing. The pre-freezing stage is the most important stage of the freeze-drying process. In this stage, sample material will need to be cooled to at least the temperature of the melting point for that sample.

After freezing and milling pre-treatment, the particle size distribution changed into 4,1% above 80 μm, 89% between 80 and 50 μm and 6,9% below 50 μm, which is in good agreement with results obtained from freeze-milling of rice (average size was 87.873 ± 4.913 μm; Ngamnikom and Songsermpong, 2011).
Freeze drying (also known as lyophilization) is a water removal process typically used to preserve perishable materials, with the goal of extending their shelf life and/or preparing them for transport.Freeze drying works by freezing the …
Spray freeze drying (SFD) is a drying process which first found applications in the field of pharmaceutical technology and has a range of applications in pharmaceutical and food technology. SFD has been used to produce high viable encapsulated probiotic cells, beverage powders with improved retention of volatile compounds, skim milk powder with ...
4) FREEZE DRYER: The material is pre-treated before freezing pre-treatment methods include freezing concentration, solution phase concentration and formulation to preserve the appearance of the product. Formulation to stabilize reactive products. Formulation to increase the surface area and decreasing
Most raw plastic material looks dry. However hygroscopic materials such as Polycarbonate, Nylon and PET to name just three, attract moisture from the surrounding air. Drying processes include Dehumidifying Dryers, Rotary Wheel Dryers, Low Pressure Dryers, Vacuum Dryers.

Some customers shred the cabbage, dip in boiling water for 2-3 minutes, then in cold water, then freeze dry. It freeze dries perfectly. However, blanching is not a requirement, as many people have found no difference between blanched and non-blanched before freeze drying.
It was hypothesized that porous excipients with suitable cushioning effect could be produced by bulk freeze-drying cum milling. This approach is postulated to be more versatile and applicable to a wider range of materials than the conventional extrusion-spheronization-freeze-drying method (11,12) as discussed previously. In this study, three ...
