Electrothermal blast drying oven selection principle

Electric blast oven is hard to say which one or several are the most important, the ideal selection must be focused according to their own conditions, and sometimes compromise is necessary. Kunshan Haida Instrument Engineer gives the following instructions to help you choose a suitable electric blast drying oven.

Applicability-------Drying device must first be able to apply to specific materials, and meet the basic requirements for material drying, including the ability to handle the material (feeding, conveying, fluidization, dispersion, heat transfer, Discharge, etc., and can meet the basic requirements of the amount of processing, dehydration, product quality and other aspects.

High drying rate—Only considering drying rate, convection drying materials are highly dispersed in hot air, low critical moisture content, fast drying speed, and convective drying. Different drying methods have different critical moisture content, thus the drying rate. Also different.

Low energy consumption ------- Different drying methods have different energy consumption indicators. In general, the thermal efficiency of conduction drying can theoretically reach 100%, and convection drying can only be about 70%.

Saving investment ----- drying equipment that accomplishes the same function, sometimes with huge differences in cost, should choose the lower one.

Low operating costs—equipment depreciation, energy consumption, labor costs, maintenance costs, spare parts costs, etc. The operating costs of electric blast drying ovens should be as low as possible.

Priority is given to the selection of desiccators that have a simple structure, adequate supply of spare parts, high reliability, and long life.

It meets environmental protection requirements, working conditions are good and safety is high.

It is advisable to make a drying experiment for the materials before the selection, and to have an in-depth understanding of the drying devices (advantages and disadvantages) that have been used for similar materials, which are often helpful for proper selection.

Not relying entirely on past experience, focusing on absorbing new technologies and listening to the opinions of experts.
