Description

Technical Field

[0001] This utility model relates to the field of coffee bean processing technology, specifically to a rapid cooling and grading conveying device for roasted coffee beans. Background Technology

[0002] After coffee beans are roasted, the internal chemical reactions continue. If they are not cooled in time, the excessive residual heat will cause the coffee beans to be over-roasted, resulting in a burnt and bitter flavor, loss of aroma, and even affecting the quality of subsequent grinding, extraction and other processes.

[0003] Currently, most existing coffee bean cooling and grading equipment on the market separates the cooling and grading conveying functions. This separate equipment architecture requires a large amount of space in the production workshop to accommodate different functions, resulting in excessive occupation of limited factory space resources and increased site usage costs. On the other hand, because each functional device exists independently, the procurement, installation, commissioning, and subsequent maintenance of the equipment must be carried out separately, which not only increases the equipment procurement cost but also the cost of daily maintenance and management. It also lengthens the production process, requiring coffee beans to undergo multiple transfers from roasting to final grading, which greatly reduces production efficiency. In addition, existing grading conveying devices are difficult to accurately sort coffee beans of different sizes, easily leading to grading confusion and failing to meet the market's demand for high-quality, finely graded coffee beans.
