Efficient oats processing requires the use of highly specialized technology that can truly be implemented by industrial machinery. The use of industrial equipment determines the expedient productivity of these industries from at least 30 tons/day. At the same time, the yield of finished products – not crushed oatmeal – is at least 60%, and its quality meets the requirements for cereals in the production of flakes.
The oats processing technology includes the following main operations: grain cleaning and fractionation, peeling and separation of peeling products. To clean the grain, sieve-air and magnetic separators of any type are used, as well as a destoner, a trier and a deawner. Fractionation of oats into small and large fractions is carried out in sieving. Further processing of oats is carried out fractionally. Peeling is carried out in centrifugal hullers, after which the pubescence hairs are isolated in a lint separator, and the husks are isolated in aspirators. A mixture of shelled and non-shelled grains is separated in paddy machines, while the non-shelled grains are sent for re-husking. In order to increase the yield of finished products before the peeling operation, it is possible to use hydrothermal processing of grain using steaming and drying. For this, a continuous type steamer and a vertical steam dryer are used. The use of steaming and drying processes requires a significant amount of thermal energy, therefore, if these operations are included in the technological scheme, steam supply to production is provided by burning oat husks.
