DRYING TECHNOLOGIES FOR HIGH TEMPERATURE SUPERCONDUCTORS

Drying Technology, 1998
Abstract High temperature bulk superconductors are conventionally produced by sintering the mixture of the oxides or carbonates of elements. In order to improve the quality of these superconductors, finer and more homogeneous powders are necessary in preparing better superconductors. These powders can be prepared using a spray drying or a freeze drying

A high-temperature drying model for softwood timber

Chemical Engineering Science, 2000
The high-temperature drying of a softwood board with relatively high permeability was modelled on a one-dimensional basis. The moisture-transport mechanism between fibre saturation and irreducible saturation was elucidated, and moisture flow within the thin layer of damaged cells at the sawn surfaces of the timber board was examined.

High Temperature Drying: Effect on Spaghetti Properties

Journal of Food Science, 1981
ABSTRACT The characteristics of spaghetti produced from two high temperature (HT) drying cycles, one featuring HT at the initial stages of drying (HT‐A) and one featuring HT during the latter stages of drying (HT‐B) were compared to spaghetti produced by low temperature (LT) drying.

Economics of High Temperature Solar Grain Drying

Transactions of the ASAE, 1981
ABSTRACT IF solar energy is to be used by farmers in grain drying, it must be economically competitive with other available energy sources. An economic analysis of high temperature solar grain drying has been made through a computer model that designs and calculates the economic feasibility of this system.

High-temperature air drying of lithium soap

Chemistry and Technology of Fuels and Oils, 1972
This method of obtaining powdered lithium stearate is a batch process, inefficient and time-consuming. In order to improve the technology of lithium soap dehydration, the integral equipment design section of the All-Union Scientific-Research Institute of Petroleum Engineering (VHIIneftemash) at the All-Union Scientific-Research Design and Construction ...

Pore Pressure and Drying of Concrete at High Temperature

Journal of the Engineering Mechanics Division, 1978
A mathematical model for water transfer in concrete above 100°C is developed. Drying tests of heated concrete are reported and material parameters of the model are identified from these tests as well as other test data available in the literature. It is found that water transfer is governed principally by the gradient of pore pressure, which represents

Dry-etching processes for high-temperature superconductors

Physica C: Superconductivity, 1992
Abstract Patterning of thin films and multilevel structures of high-temperature superconductors is a key technology for microelectronic applications. We performed a comparative study of Ion Beam Etching (IBE) and Reactive Ion Etching (RIE) processes for YBa 2 Cu 3 O 7−δ thin films.

High-Temperature Drying of Thick Concrete Slabs

Transportation Engineering Journal of ASCE, 1976
The foremost requirement for deep polymer impregnation of thick concrete slabs is thorough drying to remove all evaporable water from the pore system in concrete. To facilitate rapid repair of bridge decks with polymer impregnation, it is desirable to dry the concrete from the surface with surface temperatures not exceedings 700-800°F (370-420°C).

Energy Requirements for High-Low Temperature Drying

Transactions of the ASAE, 1978
ABSTRACT RESULTS are presented for six experiments in-volving high-temperature drying followed by in-bin cooling and low-temperature drying. Low-temperature treatments included ambient air drying starting at three moisture contents, solar supplemented drying and drying during off-peak hours.

HIGH‐TEMPERATURE DRYING‐CUM‐PARBOILING OF PADDY

Journal of Food Process Engineering, 1980
ABSTRACT Alternate methods of parboiling of paddy, in place of conventional steam‐parboiling, for obtaining improved hydration ability in the parboiled rice were explored. Ratnachudi variety, a medium‐grained, tall indica, high‐amylose rice, was used. The paddy was soaked in warm water to a saturation moisture level (ca 30%, w.b.). The soaked paddy was
