Abstract

The invention relates to large-scale production and can be used in the production of barley flakes. The purpose of the invention is to reduce the production time of barley flakes by speeding up the saturation of the grain with moisture and eliminating the sticking of the grains when the moisture is increased. The grain is heated with steam to 70-80 ° C, followed by moistening it to 21-25% with hot water at the same temperature and evaporating for 2 hours. Obtained after peeling and grinding the croup is cooled to 20-26% with saturated steam at a pressure of 0 , 02-0.03 MPa for 1.5-2.0 minutes.

Description

The invention relates to large-scale production and can be used. vano when making flakes of barley.

The purpose of the invention is to reduce the production time of barley flakes by speeding up the saturation of the grain with moisture and eliminating the sticking of the grains when the moisture is increased.

In the method of obtaining barley. cereal barley flakes are heated with steam to 70-80 ° C, moistened with water at the same temperature up to 21-25%, volatilized for 2-4 hours, dried with an air stream with a temperature of 80-90 C to a humidity of 17-20%, shelled grind, and grits douvlazut up to 20-26% saturated steam at a pressure of 0.02-0E03 MPa for 1.5-2.0 minutes, flatten and dried.

Preheating the grain with steam and moistening it with hot water

accelerates the process of moisture absorption by 4-5 times, and humidification by steaming the grits obtained after grinding the saturated steam before grinding improves its plastic properties, improves the quality of the flakes.

Example 1. Before moistening, the grain is heated with steam to reach 70 ° C, "moistened with water at a temperature of 70 ° C to a moisture content of 21%, steam for 2 hours, steamed, dried with an air stream at a temperature of 80 ° C to a moisture content of 17%, peeled with getting cereals. The croup is douvlaznat saturated steam at a pressure of 0.02 MPa for 1.5 minutes to a moisture content of 20%, flatten to obtain flakes and dried.

The flake yield is 77.6%, flakes are durable with smooth edges,

Example 2 Before humidification, the grain is heated with steam to reach 75 ° C, moistened with water at a temperature of 5 ° C to a moisture content of 23%, coiled for 3 hours, steamed, dried with an air stream at a temperature of 85 ° C to a moisture content of 18%, shelled Ylifuyut with obtaining cereals. The groats are saturated with saturated steam at a pressure of 0.025 MPa for 1.75 minutes before. moisture 23%, flatten to obtain lozenges and dried. The yield of flakes is 77.6%, flakes are durable from the IJJH edges, there is no crumb. The flake production time is 2. h 1.75 min.

Example 3. Grains are heated with steam before moistening.

$ 0 C, moistened with water with a temperature of $ 0 ° C to a moisture content of 25%, k treated for 4 hours, steamed, dried with an air stream with a temperature of 90 ° C to a moisture content of 20%, shelled, and dried to form croup. The groats are moistened with saturated steam at a pressure of 0.03 MPa for 2 minutes to a moisture content of 26%, flattened to form Flakes, and dried. The yield of flakes is 77.6%, flakes are durable with smooth edges, there is no crumb. The flake production time is 2 hours and 2 minutes.

When the temperature of the grain of barley is below 70 ° C, the water is humidified at 70 ° C, and the coarser is moistened with saturated steam with a pressure below 0.02 MPa for 1.5 minutes, the time of the technological process for barley flakes increases, the process is stretched and at a grain temperature of 20 ° C and moistening with water, that Xe temperature reaches 16-18 h, and the cereal is moistened with saturated steam with a pressure below 0.02 MPa less than 1.5 min

does not provide plasticity to the grits; flakes are not strong with torn edges. Flake yield is reduced to 50-60%.

When the heating temperature of barley steam is above 80 ° C, moistened with water of the same temperature, and also when the cereal is moistened with saturated steam pressure of more than 0.03 MPa and more than 2 minutes, the technological process does not decrease in time, and the energy costs significantly increase, the efficiency of the process decreases. The flakes turn brown.

Thus, the optimal parameters are given in examples 1-3. At the same time, the production time of the flakes is reduced by more than 6 times (16-18 h by a known method and 2 h 2 min by the proposed method), the quality of the flakes is standard.

Claims (1)
