Solution Overview
Problem
Conventional coffee bean roasting methods result in flavor loss, inconsistent roasting, production of harmful by-products, and high energy consumption, with drum and hot air roasters causing scorching, carbonization, and air pollution.
Innovation Solution
A system that fries and roasts coffee beans in an anaerobic cooking oil environment, using conduction and centrifugation to reduce carbonized particulates and volatile organic compounds, and centrifuges to remove excess oil, ensuring consistent roasting and reduced fat content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional drum or hot air roasting methods are used to roast coffee beans, then the roasting process can be completed, but the beans are subject to scorching, carbonization, and flavor loss with harmful by-products
Solution Approach 1:
The patent applies this principle by using cooking oil as an inert frying medium that creates an oxygen-limited environment during the frying process. This prevents combustion and oxidation that cause scorching and carbonization in conventional air roasting, while still achieving the desired roasting temperatures and flavor development through controlled frying followed by centrifugal separation.
2Ease of manufacture
If conventional air roasting is used, then the process is simple, but it produces air pollution and harmful volatile organic compounds
Solution Approach 1:
The cooking oil frying medium creates an inert environment that prevents the formation of harmful volatile organic compounds and air pollution associated with conventional air roasting. The oil atmosphere suppresses combustion reactions while allowing thermal processing to proceed, eliminating the air quality issues of traditional methods.
Solution Approach 2:
The patent extracts and removes the harmful by-products through centrifugal separation. The centrifuge extracts excess oil and separates it from the roasted coffee beans, removing the medium that prevented harmful emissions during frying while eliminating residual oil and contaminants from the final product.
3Reliability
If deep frying with cooking oil is used, then consistent roasting with reduced harmful emissions is achieved, but excess oil must be removed from the beans
Solution Approach 1:
The patent applies this principle by using a centrifuge to extract and remove excess cooking oil from the fried coffee beans. The centrifugal force separates the oil from the beans based on density differences, effectively removing the unwanted substance while preserving the roasted coffee product.
Solution Approach 2:
The system discards excess oil through centrifugal separation while recovering the roasted coffee beans as the final product. The separated oil can be discarded or potentially recovered for other uses, while the beans are collected with reduced fat content and improved quality.
4Productivity
If conventional roasting methods are used, then the process is straightforward, but energy consumption is high due to scorching and incomplete roasting
Solution Approach 1:
The patent changes the fundamental parameter of the heating medium from air to cooking oil. This parameter change allows for more efficient heat transfer and more consistent temperature distribution during the frying process, reducing energy waste from scorching and incomplete roasting that plagues conventional air-based methods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves consistent roasting with reduced harmful emissions, lower fat content, and improved flavor profile by using cooking oil as a heat source and centrifugation to minimize scorching and oil retention.
Implementation Method 1
heating the beans to a desired internal temperature in a frying medium (e.g., oil)
Implementation Method 2
a portion of the frying medium is then removed from the coffee beans (or other food product) through the use of a centrifuge

AI summary
Some implementations of the described methods relate to a process for frying coffee beans (and/or another food product) in a fry medium (such as cooking oil) and then centrifuging the coffee beans (and/or other food product) to remove a significant portion of the fry medium. Although the frying and centrifugation can occur in separate devices, in some cases, the described systems comprise a device that acts as both a fryer and a centrifuge. Indeed, in some cases, after the coffee beans (or other food product) has been fry roasted in a perforated container (e.g., a basket), the fry medium is drained from the container, and container is spun. In some cases, liquid nitrogen is also applied to the beans (or other food product), before and/or after being fry roasted. Other implementations are described.
