METHOD FOR DETERMINING MAXIMUM TEMPERATURE OF DRYING AGENT WHEN DRYING THERMOLABILE PRODUCTS Russian patent published in 2009 - IPC F26B3/00 

FIELD: heating systems.

SUBSTANCE: method for determining maximum temperature of drying agent provides for determination of maximum temperature and heating period of the product by an experiment, and is based on the tests performed for many times, and as per the results of which there determined is heating period of the product, provides qualitative measures of the specimens within the limits specified by the appropriate standard, and on condition that product heating temperature and exposure period during drying process do not exceed appropriate values when the specimens are tested. The new feature of the method is that two batches of specimens of thermolabile products are used for experiments; specimens are subject to drying, at that, in the first specimen batch, drying period is determined every 10°C to the final product humidity, and in the second one - maximum drying period at which qualitative measures of the product remain within the limits specified by the appropriate standard. Then on the basis of the obtained data, there built is combined diagram of drying period to final humidity and maximum drying period versus reciprocal value of absolute drying agent temperature, and maximum allowable temperature of drying agent is determined as per crossing point of those diagrams for each concrete thermolabile product.

EFFECT: method provides the possibility of using the obtained results for choosing temperature drying conditions, thus improving the quality of finished products.
