Study And Experiment On The Method Of Remove Coconut Fiber From Wire Roller Brush

The coconut processing industry is the lifeblood of these regions in Hainan and southeast Asia.The total production of coconut in Hainan is nearly 2.4 billion,and the total annual coconut consumption of Hainan is 2.6 billion.As a raw material for food processing,coconut water and coconut have a huge share in the consumer market.The first important step is to get coconut water and coconut.The artificial removal Coconut coat is main processing way,which use of machetes cutting coconut fiber.After that,the operator tore the coconut fiber from the coconut shell.which is inefficient and vulnerable to injury operator,hinders the development of coconut processing enterprises.Because the stripping efficiency is influenced by the cutting tool performance and the method of removing coconut fiber.it is an important method to improve the cutting efficiency by optimizing the cutting tool's parameters and researching scientifically.Many animals have evolved to have very good feeding organs for eating nuts.For example,the worm claw toe,squirrel incisors,etc.Have the arc to remove the nut shell and the cutting edge structure.The process of eating nuts in rodents is similar to the process of tear the coconut fiber,so this paper use the mole claw toe as a bionic prototype to design a device to remove the coconut fiber with a steel wire roller.In order to improve the efficiency of remove the coconut fiber,this paper proposes amethod to do it.Through bionics principle,design a equipment include a steel wire roller to remove the coconut fiber.Then,use the 3D software to implement the design plan.After this,checked and optimized the key parts by use the classical mechanics design method.The stress distribution of roller brush is improved by using finite element method.Use optimized design methods such as finite element method and penalty function method to optimize roller brush shaft and coconut clamping cantilever.Use the Design-Expert 10.0 software and the Response surface analysis to Analysis the effected of different roller brush to remove the coconut fiber,and get the optimal combination parameters.According to the production requirements of Hainan local coconut processing enterprises,designed and made an indoor test device to remove the coconut fiber.The results show that the reasonable design of steel wire can obviously improve the removal efficiency.After analyzing the experimental data,the conclusion is as follows:?Determine the optimal combination of the remove the coconut fiber equipment solutions is use the nylon roller substrate planting steel wire brush roller,roller rotation speed to 970 rad/min,the diameter of the brush is 6 mm and brush plant spacing of 8 mm,and through repeated test,The optimal solution combination satisfies the technical requirements of the coconut deep processing enterprise.?The bionic wire roller brush removes the coconut fiber equipment maximum theoretical removal efficiency of coconut skin is 10 a/min.The diameter of the steel wire and the rotating speed of the steel wire roller is more affected than the spiral angle and the number of threads for the efficiency of remove the coconut fiber.In a reasonable combination of steel wire diameter,spiral angle and number of threads,the efficiency of the remove the coconut fiber increases with the increase of the roller speed,and is in accordance with the Normal distribution.If the wire diameter is too small,the efficiency of the remove the coconut fiber improvement is not obvious.If the steel wire diameter is too big,steel wire roller will damage the wood coconut shell,do not matching the coconut processing technical requirements.
