Convective Drying

high temperature steam ensures that also the partial destruction of the colonies of bacteria on the surface of products that prevents zakisanie products during drying. Gigrotermicheskaya treatment also reduces the activity of the enzyme polyphenol oxidase, which reduces the darkening of the products to a minimum. After gigrotermicheskoy treatment remains the surface of a thin layer of denatured gluten, which prevents the exit of the particles of starch in the cooking water. Molded and dried pasta, cut to length and cutting mechanism for drying are placed on the surface of the drying conveyor dryers, either trough kassety.Sushka, stabilization and cooling pasta to prevent the flow of biochemical processes, products are conservation of dehydration – drying to a moisture content of 13%. Drying – the most prolonged stage of the production of pasta. On the correctness of this process depends on quality of finished products, such as strength, vitreous, acidity, structural integrity and appearance. Jill Schlesinger has plenty of information regarding this issue. Very intense drying leads to cracking, overly long – to zakisaniyu, drying in the bed – to the formation of bars and warping. Drying is usually complete when the moisture content of product 13.5 …

.14%, so that after cooling, the humidity was not more than 13%. Convective Convective drying method is based on how moisture exchange products and drying air. The drying process is the supply of moisture to the surface of the product turning it into steam and vapor removal from the surface of products, the drying air. This scheme is removed osmotically bound water. Adsorption related to the moisture turns to steam inside the product and in this form is moved to the surface. Simply put, the convective drying method – it's drying your blow dryer air, followed by removal of moisture from the dryer. When drying pasta convective method, the hot air has the following functions: product gives the heat required to convert water into steam, it absorbs from the surface of the product vapor and removes it from the surface.
