Compared with the prior art, the invention has the beneficial effects that:

1) the coffee peel separation and screening equipment comprises a stone remover, a shell breaking machine, an impurity removing machine, a shell removing machine, a screening machine and a color separating machine which are mutually connected by using a lifter, then raw materials sequentially pass through the stone remover to remove stones, the shell breaking machine to break shells and the impurity removing machine to remove impurities with density higher than that of coffee in the coffee peel separation and screening equipment, the shell removing machine to remove shells of coffee beans, the screening machine to grade the coffee beans according to particle sizes and the last step to grade the coffee beans according to colors, operators only need to add the coffee beans into a material inlet of the first lifter in the whole processing process, collect impurities at impurity outlets of the stone remover, the impurity removing machine and the shell removing machine, and then collect the graded coffee beans at the last screening machine and the color separating machine.

2) The winnowing pan of the hoister in the coffee pericarp separating and screening equipment adopts a mode of combining the bottom winnowing pan and the bottomless winnowing pan, and a certain distance is required between the winnowing pans of the ordinary hoister for facilitating feeding, so that the material transportation efficiency is reduced; if the width of the winnowing pan is increased, the problem of difficult steering can be caused by the overhigh winnowing pan at the positions of the upper and lower two-end winnowing pans, and the winnowing pan is easy to damage.

3) The bottom end of the bottomless dustpan used in the invention is provided with the bending part, so that the materials can be prevented from falling off in the transportation process; the distance between two adjacent winnowing pans is greater than d-tan A, so that the situation that materials cannot reach the winnowing pans due to too small distance between the winnowing pans is avoided, the optimal distance is d-tan A, the materials can reach the winnowing pans, the winnowing pans can be filled, and the transportation efficiency can be guaranteed.

4) The screening machine is internally provided with a plurality of screen meshes with different mesh sizes, the mesh sizes are sequentially reduced from top to bottom, the largest coffee beans are collected at the outlet connected with the screen mesh on the uppermost layer, and the coffee beans collected from top to bottom are sequentially reduced.

5) After the screening machine classifies the coffee beans according to the particle size, the coffee beans which need to be further classified according to the color are loaded into a color sorter through a lifter and classified according to the color.

6) Since the coffee beans are not regularly round, in order to increase the efficiency of coffee bean screening, the meshes of the drying net are set to be oval, wherein the minor axis of the oval is set in the vibration direction.

7) Because coffee is through removing the stone, breaking the shell, edulcoration, removing the shell and screening step, wherein have some powder dust adhesion on the coffee bean surface, these tiny dust can be floated in the middle of the air by the floating when collecting the coffee bean, cause the injury to operator's health, consequently set up the dust absorption mouth in discharge gate below, utilize the dust of air exhauster with the miscella oil in the coffee bean to get rid of.

8) The dust removal pipe is internally provided with a high-pressure nozzle, and when the dust in the dust removal pipe is accumulated too much and cannot be discharged, the high-pressure nozzle is opened to spray high-pressure gas to clean the dust in the dust removal pipe.

9) The stone remover, the impurity removing machine and the chopping board in the shell removing machine are provided with sieve pores and protrusions, the protrusions are provided with openings on one side, coffee beans and impurities are separated according to density, and some small-particle impurities can pass through the openings and the sieve pores and are separated from the coffee beans.

10) Because coffee beans have some impurity or coffee beans card in the screen cloth or shake the space on the board at the in-process of screening or edulcoration, influence the effect and the efficiency of screening and separation, consequently shake board and screen cloth below and be provided with high pressure gas blowing device, regularly open and close as required, will block the coffee beans or impurity on screen cloth and shake the board and blow away, prevent to shake board or screen cloth jam.
