The invention discloses a boiled egg shelling apparatus and relates to a food processing apparatus. The boiled egg shelling apparatus comprises a shell breaker; the shell breaker is a container and is cylindrical in shape; a central axis hole is formed in the bottom surface of the shell breaker and connected with a power apparatus; the power apparatus drives the shell breaker to rotate; a pair of shelling shafts are arranged in the shell breaker; a gap between the shelling shafts is smaller than the outer diameter of an egg; the pair of shelling shafts rotate in the opposite direction at the same speed; a water container is arranged below the shell breaker; the lower part of the water container clings to an electric heating plate; the motion directions of the close ends of the shelling shafts are both upward; cavities are formed in the shelling shafts; a plurality of air holes connected with each cavity are formed in the surface of the shelling shaft; an included angle of 30-90 degrees is formed between each air hole and the radial direction of each cavity; an air compressor is arranged and connected with the cavities; an air outlet is formed in the top of the shell breaker; and arc-shaped baffles are arranged at the lower parts of the shelling shafts. According to the apparatus, automatic shelling can be realized and the egg can be prevented from being scratched.

Electrostatic Controllable Abrasive Flow Machining Method Based on Charge Tip Aggregation Effect
ActiveCN109551374BControllable distributionReduce particle size unevennessAbrasive machine appurtenancesParticle flowEngineering
The invention discloses a static electricity controllable abrasive particle flow processing method based on a charge tip aggregation effect. An abrasive particle flow with non-electrolyte as a carrieris subjected to a high-voltage electrostatic field to be charged, so that the distribution of the abrasive particles in the flow field can be controlled, and negative influences produced by abrasiveparticle size unevenness and large-particle-size abrasive particles in the processing process are reduced; an electric field is applied to the flow field, the distribution characteristics of the abrasive particles with the negative charge on the collision area on the surface of a workpiece with the positive charge are changed through the electric charge tip aggregation effect, the possibility of collision of the abrasive particles to the microscopic surface crest of the workpiece is increased, workpiece surface crest removal is accelerated, the flow-in angle of the abrasive particles is periodically swung in a pulse mode, the optimal polishing alternating force acting on the workpiece is obtained by effectively adjusting and controlling the pulse frequency and the swing angle, and it is ensured that the high-quality surface is obtained on the premise of efficient removal.
