However sometimes it is not enough air in a cyclone and exceeds its emissions in environment MPE (maximum permissible emissions), (according to SN-1042-7Z) 0,5 g/sec. are equal;
Indicators of quality of pasta are: appearance, taste and a smell, existence of broken lines, the deformed products, and also crumbs, humidity of products, their acidity, a razvarivayemost, durability absence in them granary wreckers and metalimpurity.
When using a wheaten gluten the content of albumens in products can increase by 30 - 40%. The gluten is withdrawal by production of wheat starch and its use as the dresser economically expediently.
Humidity of products should not exceed 13% (in products for baby food of 12%). For the pasta sent to the remote areas (Far North, Sakhalin, etc.), moisture content has to be no more than 11%. Acidity of products has to be no more than 3,5-4 . The increased acidity of products arises at violation of the mode of drying, use of a substandard flour.
Cooling of the dried-up products. This process is necessary to level high temperature of products with air of packing office. If to pack pasta without cooling, evaporation of moisture to proceed already in packing that will lead to reduction of mass of the packed products.
Pasta contains (in %): waters-13; proteins - 10,4-11,8; fat - 0,9-2,7; carbohydrates 72,2 - 75,2; celluloses – 0,1-0,2; vitamins B, RR. Power value 100g. macaroni of-332-341 kcal, or 1389-1427 kJ.

Proteins of pasta are acquired for 85%, fats for 93%, carbohydrates for 96%. Among mineral substances there is a lot of phosphorus, potassium, sodium, but it is not enough calcium, also pasta contains insufficient amount of such not replaceable amino acids as a lysine, methionine,.
Weight and packing products have to be packed into transport container: boxes wooden, boxes board, from corrugated fibreboard, boxes from a wattled interline interval and from a cast cardboard with a net weight no more than 30 kg, are covered inside by a white brown paper which upper edges are bent so that the ends would block it each other.
