| Buckwheat as a natural food,the demand at home and abroad is steady.Therefore,buckwheat rice processing industry in China has a wide range of development prospects.The reduction in power consumption in buckwheat processing industry has an important impact on productivity and economic efficiency.The existing buckwheat rice process lacks the test and analysis of power consumption.In order to clarify the power consumption of buckwheat rice processing,we designed and manufactured a buckwheat shelling unit comparable to the set of buckwheat rice production.We can use the unit to achieve continuous shelling cycle of buckwheat and a single buckwheat shelling unit power consumption testing.Based on the power consumption detection method of rice processing equipment,the power consumption test method of buckwheat shelling unit was designed.Buckwheat with ?4.0?5.0mm particle size were used as the test material,the opening degree of the shelling machine hopper door and the rotating speed of motor of the vibrating screen were the parameters.The non-sieving rate and the broken rice rate were used as the restriction.Power consumption of per ton of buckwheat shelling unit was detected.The results show that the power consumption,broken rice rate and non-sieving rate of shelling unit is the lowest when the opening degree of hopper door is 20mm and the rotating speed of motor of the vibrating screen is 2058r/min.The power consumption and the broken rice rate decreases with the increase of particle size of buckwheat,and the rate of separation is increased with the increase of particle size.Compared with the original sieve,the power consumption of the new sieve is reduced by 4.3%,the broken rice rate is reduced by 1.36%and the non-sieving rate is reduced by 0.72 ‰.The results show that we can improve the production efficiency of buckwheat shelling unit and reduce the power consumption through the use of the optimum working parameters and new size sieve. |
