43 results about "Coffee roasting" patented technology

Roasting coffee transforms the chemical and physical properties of green coffee beans into roasted coffee products. The roasting process is what produces the characteristic flavor of coffee by causing the green coffee beans to change in taste. Unroasted beans contain similar if not higher levels of acids, protein, sugars, and caffeine as those that have been roasted, but lack the taste of roasted coffee beans due to the Maillard and other chemical reactions that occur during roasting.

The door opening and closing control assembly includes a door rotation switch component, a sliding member, a bean outlet door, a spring, and a spring retainer. When roasting is complete and the door needs to be opened, the door rotation switch component can be manually adjusted from a first connection position to a second connection position. During this process, the component drives the sliding member, which, since the bean outlet door is connected to the sliding member, moves the bean outlet door away from the middle plate, thus opening the door. The switch component can be released to remain in the second connection position. When the door needs to be closed, the door rotation switch component can be manually adjusted from the second connection position to the first connection position. The spring, through its rebound, pushes the sliding member, causing the sliding member to move the bean outlet door closer to and abut against the middle plate, thus closing the door.
