A Study on the Removing Pulp Machine of Seed Water Melon

Seed water melon is a special local product in Gansu Province. Today only the seeds are extracted while the rest of the melon is discarded. This not only produces an enormous amount of waste,but also pollutes the environment,so it is necessary to extend a comprehensive utilization of this product. Every part of the melon is useful. The seeds are sold as a popular food,the juice is canned as a medical beverage,the pressed pulp is the base for preserves and the rind is dried and sold as a traditional Chinese medicine.In order to utilize the melon pulp to develop a kind of efficient removing pulp machine is needed. According to the theory of conjugate cut,we have designed a modern removing pulp machine. Its conjugate motion depended on worm drive. The rotation of cutting tools was made by bevel-gear planetary train. A cam and fourbar linkage supplied melons continuously. The machine was efficient, smooth running with a high degree of mechanization. About 6000 kg of melon can be proccessed per hour,which was about 12 times over that of manual productivity.
