Paint Removal

A comparison is made between the laser and sandblasting methods for removing paint from industrial facilities. The advantages of laser ablation are discussed. The possibilities of laser paint removal systems - stationary and moving - are shown. The main factors influencing the laser ablation process and the indicators that determine the quality of the obtained surface are systematized. Researchers' publications on this technological process are analyzed.

Optimization of structural and kinematic parameters of separator of vegetable and melon crops It was determined in the article the optimization criteria, which were used to evaluate the quality of the technological process. The main factors influencing the operation of the vibrating separator are revealed: the angle of inclination of the lattice surface, the frequency of oscillations of the sieve, the amplitude of its oscillations, the angle of application of the oscillation force and the length of the sieve. The optimization criteria were chosen: purity, magnitude of injury and the level of seed loss. The ranges of optimal combination of independent factors are indicated. Keywords: vegetable and melon crops, separator, kinematic and design parameters.

Quality Of Products

Laser ablation presents a promising technique for material processing. The quality of products is strongly influenced by the properties of the laser induced plume. In compressible flow, the ambient conditions can be transmitted upstream. Therefore, the laser ablation process is strongly affected by the ambient conditions. In this paper, the effects of laser intensity, back pressure and temperature on the laser induced plume were studied using a numerical model, which calculates the density, pressure and temperature of the laser induced plume at different laser intensity and ambient conditions. The results are in agreement with experimental results available in the literature and can be used for the optimization of the pulsed laser deposition process.

Main Factors

Of the four main factors commonly regarded as influencing keeping properties of ghee, viz. moisture content, acidity, heat treatment and type of bacterial culture used in souring, the heat treatment was found to be the most important.In general, the higher the final temperature (110° C. and higher) attained during evaporation, the better were the keeping properties of the product, providing that the butter had been heated in contact with curd, boiled as rapidly as possible, and given a minimum amount of stirring.The improved keeping properties conferred on ghee heated to 110–150° C. were promoted by antioxidants (apparently phospholipids) extracted from the curd during cooking.Initial acidity and moisture contents had no effect on storage life of ghee at 38° C., and the practice of grading ghee according to its acidity would appear to be of questionable value. Souring of milk to give 2·5–3·0% lactic acid and the accompanying desirable flavour did not detract from the keeping quality of the ghee made from it.The type of bacterial culture used for souring had only slight influence on keeping quality of ghee, but a marked influence on flavour.Storage life of ghee at 38° C. (‘Indian summer temperature’) could be predicted with fair accuracy from its rate of oxidation at 100° C. in a ‘Swift oxidation tester’.
