Basic knowledge of boutique coffee skills of selecting coffee beans with vibrating screen
I saw on the Internet yesterday that someone asked if the vibrating screen could screen peanuts and coffee beans, and the answer was yes. In the following, some problems and solutions of vibrating screen in screening these two materials are discussed. First of all, customers need to know the number of peanuts and coffee beans, and then choose the appropriate sieve, which is like screening peanut and coffee beans. Secondly, it depends on the output of the customer to decide which type of machine to choose, such as rotary vibrating screen or linear vibrating screen and other screening equipment. All kinds of equipment have their own advantages. In the case of large handling capacity, the linear vibrating screen can be selected. Take the linear vibrating screen for example, the linear vibrating screen uses two special vibrating motors as the exciting source, so that the material is thrown on the screen surface and moves forward in a straight line at the same time. The material smaller than the sieve hole goes through the sieve hole and falls to the lower layer through the sieve hole, and after continuous jumping, it flows out through the outlet to complete the material classification operation. And can be stacked multi-layer screen, can screen a number of grades. For example, if the first layer is used to remove the large sundries in peanuts, peanuts fall to the second layer through the screen, and the peanuts larger than the second layer can run continuously to the outlet along the vibration force of the screen, and screen out the required level. impurity powder less than the number of mesh can be discharged in the third layer. By the same token, the same applies to screening coffee beans. And compared with other screens, SZZ series linear vibrating screen has the advantages of high screening accuracy, simple structure, convenient maintenance, low energy consumption, low noise, good sealing, favorable environmental protection, replaceable many kinds of screen, long service life and so on.
