Description

Technical Field

[0001] The utility model relates to the technical field of coffee screening, in particular to a coffee screening mechanism capable of recycling coffee shells. Background Art

[0002] The coffee screening mechanism for recyclable coffee shells is a mechanical equipment that plays an important role in the coffee bean processing process. Its main function is to separate the coffee beans from their shells through a series of screening and separation steps, and recycle these shells. The mechanism is usually composed of a feed hopper, a screening net, a conveyor belt, a wind or vibration separation device and a recovery system. When working, the coffee fruit or the depulped coffee beans are fed into the feed hopper, and then pass through the screening net to separate the coffee beans and coffee shells according to the weight and size differences. The coffee beans fall through the screening mesh, while the lighter coffee shells are screened out, and then the separated coffee beans and coffee shells are transported to different collection points by the conveyor belt. The coffee shells enter the recycling system and may be used as organic fertilizer, biomass energy or other purposes, while the coffee beans continue to undergo subsequent processing, such as drying, silver skin removal, etc., thereby achieving environmental protection, high efficiency and resource recycling in coffee processing.

[0003] Currently, most of the existing coffee shelling machines are of the single-fan separated type. However, when there are many coffee shells, the wind force blown out by the fan is limited, resulting in part of the shells being unable to be pushed by the wind, resulting in part of the shells being collected together with the coffee beans, resulting in a low bean output rate and poor performance. Therefore, a coffee screening mechanism that can recycle coffee shells is proposed. Utility Model Content
