Abstract

The invention relates to the technique and technology of grain processing and can be used in the system of bread products, elevators, grain receiving plants, laboratories, science. The invention relates to the technique and technology of grain processing can be used in the system of bread products, grain elevators, grain receiving enterprises. these, in laboratories, research institutes and especially in large enterprises, processing pea seeds, in the production of cereals or flour. The chain of the invention is to improve the quality of the cereal. but research institutes and especially in large enterprises processing pea seeds in the production of cereals or flour. The purpose of the invention is to improve the quality of cereals. The method of production of pea groats is as follows: the seeds are cleaned in air-sieve separators, they are moistened to 14-16% from large and small impurities, they are drained for 20 minutes. Then the seeds are subjected to mechanical action in the field of centrifugal seeks with an acceleration of 3-5g to obtain a mixture of whole normal and crushed damaged and damaged seeds. Then crushed and spoiled seeds are separated from this mixture on sieving. In this case, the crushed damaged and spoiled seeds are removed. Normal seeds are fractionated. Next, the large and small fractions are subjected to separate shells and the removal of peeling by-products. 1 tab. -, 2 In the method of production of grains from peas, including the removal of large and small impurities, moistening and drying, separation of seeds into 5 large and small fractions, separate peeling of these fractions, removal of peeling by-products, moistening of seeds is carried out up to 14 -16%, moistened, peeled seeds, prior to fractionation, are subjected to mechanical stress in the field of centro d 4 cl 4 oo cl CD

runaway forces with an acceleration of 3-5g, followed by separation of the crushedJ from the estimated estimate of damaged and spoiled seeds. At this, only normal seeds are subjected to fractionation.

Seed moistening is necessary in order to increase the yield of JHocTb seeds and that cat aM reduce the number of normal split seeds, since a deviation from the indicated humidity towards a decrease and an increase leads to a decrease in the results of the selection of damaged and spoiled seeds.

Mechanical impact - a blow in the field of centrifugal forces with an acceleration of 3-5g is necessary in order to use the difference in strength j to split the damaged and spoiled seeds. The use of another acceleration does not give positive results, since going beyond the indicated limits leads either to splitting of the normal seeds (in case of acceleration increase), or to non-splitting of damaged and damaged seeds voosche (in case of decreasing acceleration). The separation of crushed and damaged seeds from the bulk of the seeds after mechanical action is necessary so that only normal quality raw materials can be used for further processing.

The method for producing pea groats is as follows. The seeds are cleaned in air sieve separators from large and small impurities, moistened to 14-16%, and folded for 20-30 minutes. Seeds are subjected to mechanical action in the field of centrifugal forces with an acceleration of 3-5g to obtain a mixture of whole (normal), split (damaged) and spoiled seeds. Then crushed and spoiled seeds are separated from this mixture on sieving. In this case, the crushed damaged and spoiled seeds are removed. Normal seeds are fractionated. Further, the large and small fractions are crushed under separate peeling and lifting of the peeling by-products. P r and m p 1 o Received grits from raw peas with an initial moisture content of 9–8%, containing 2% of damaged and spoiled seeds. The seeds were cleaned about large impurities, small impurities,

Moistened up to 16% and washed for 20 minutes. Then, the moistened seeds were subjected to mechanical action in the field of centrifugal forces (for example, in a centrifugal peeler) with an acceleration of 3j to obtain a mixture of whole normal and crushed damaged and damaged seeds. Then, split and damaged seeds were separated from the mixture obtained on the screens. Normal seeds were divided into large and small fractions and peeled separately on a husk.

The yield of whole cereal was 38.9%, and crushed - 42.0%. There were no damaged seeds and spoiled seeds in the whole and in the chopped croup,

EXAMPLE 2. The production of cereal was carried out analogously to example 1, but unlike example 1, the mechanical action in the field of centrifugal forces was carried out with an acceleration of 5g.

The yield of whole cereal was 39.0% and the output was split - 42.1%. Damaged and spoiled seeds in the cereal were absent.

EXAMPLE 3. The preparation of the cereal was carried out analogously to example 1, but unlike example 1, the seed was moistened to 14%.

The yield of whole cereal was 38.8% and the prick was 42.9%. Damaged and spoiled seeds in the croup were absent.

To prove the optimality of the selected parameters and to prove the impossibility of achieving a positive effect when going beyond their limits, additional studies were carried out.

The effect of the degree of moistening of the seeds on the percentage of release of damaged and spoiled seeds is confirmed by Example 4.

EXAMPLE 4 The preparation of the cereal was carried out as in Example 1, but the raw materials were not moistened.

The yield of whole cereals was only 29.5%. The number of damaged and damaged seeds in it is 0.8%. The yield of split cereals - 32.2%, damaged and spoiled seeds in it 1.6%.

The low humidity of the raw material leads to the fact that during mechanical

the action splits a large number of normal seeds, i.e. no such strength is required with such moisture.

The effect of the acceleration on the percentage of release of damaged and damaged seeds is confirmed by examples 5,6.

EXAMPLE 5. The preparation of the cereal was carried out analogously to Example 1, however, the mechanical action in the field of action of the torsional forces was performed with an acceleration of Ig.

The yield of whole cereal was 38.8%, and chopped - 42.8%. The number of damaged and spoiled seeds in the whole groats was 0.35%, in the stab - 4.0%.

Part 6, Production of the grits was carried out analogously to example 1, however, the mechanical action in the field of centrifugal forces was carried out with an acceleration of lOg.

The yield of whole cereal was 26.6% and chopped - 30.9. Damaged and spoiled seeds in the whole groats were absent, and in the chopped they amounted to

0.5%.

The low acceleration in example 5 makes it impossible to use the difference in strength of damaged and oiled seeds. Cleavage occurs only when peeling and they almost completely go to the grits.

A very large acceleration (in example 6), despite the optimum humidity, leads to splitting of normal seeds and reduces the output

cereals.

The results of the examples are summarized in

t ablitz.

As can be seen from the table, the best results are obtained in examples 1, 2.3. Processing of raw materials in these examples was carried out according to optimal parameters; moistening up to 14-16%, mechanical action in the field of centrifugal forces with an acceleration of 3-5g. Kolo, rho; -.

There are no damaged or spoiled seeds in the whole, or in the split croup.

Example 4 shows the effect of the degree of moisture on the percentage of excretion. damaged and spoiled seeds The yield of whole cereal was only 29.5%, choking - 32.2%. In the croup, seeds of damaged and damaged seeds are found.

The effect of acceleration is shown in examples 5,6. The low acceleration in Example 5 makes it impossible to use the IS difference in strength of damaged and damaged seeds. Their scaling occurs at the moment of peeling and they are almost completely transferred from the raw material to the grits. A very large acceleration, despite the optimum humidity in Example 6, leads to the splitting of normal seeds and a decrease in the yield of cereals.

The use of the invention in comparison with the prototype allows improving the quality of the cereal by removing the damaged and damaged seeds, increases the output of the cereal of higher grades.
