Roast Flask

The roastFlask is a machine used to enhance and maintain the flavor and aroma of coffee beans. The following are some objectives in developing a personal coffee roaster:

Improvement of taste and aroma of coffee beans: Roasting involves heating coffee beans at high temperatures to evaporate moisture and oils within the beans, triggering a complex chemical reaction that creates flavor and aroma. The goal is to roast coffee beans according to personal preferences, resulting in a richer and deeper taste and aroma.

Consistent quality maintenance: Coffee roasting can vary greatly depending on factors such as time, temperature, and humidity, resulting in changes in flavor and aroma. It is important to develop a coffee roaster that minimizes such variations and maintains consistent quality, even when individuals roast coffee beans themselves.

Small-scale production for on-demand needs: To maintain consistent quality of roasted coffee beans, a large quantity needs to be processed at once. However, the goal of this development is to produce a uniform roasting result for a small quantity of beans in a shorter amount of time, similar to what can be achieved with large-scale roasters.

Reduction of greenhouse gas emissions: Coffee roasting consumes a significant amount of energy and is a major contributor to greenhouse gas emissions. Developing a coffee roaster that emits fewer greenhouse gases and reduces environmental pollution is also a goal.

User-friendliness: Coffee roasters are generally used by coffee experts or companies, and have limitations that prevent general users from using them. Therefore, user-friendliness and ease of operation are important factors to consider. The objective is to develop a roasting machine with a user-friendly interface and convenient features.

Everyone enjoys the best coffee: Everyone expects good coffee, but unfortunately, in many cases, the roasted coffee beans that are distributed reach their expiration date limit before they can be enjoyed in their optimal condition. As a result, more than two-thirds of a bag of coffee is often consumed in a poor-quality state. Fortunately, the personal roaster solves this problem by allowing you to easily roast a small amount of coffee at home and consume it within a week, just like freshly baked toast. The ultimate goal is for the general public to enjoy the freshest and best-tasting coffee possible.

Roastflask is a personal coffee roaster that has been designed to automate the roasting process while allowing for precise control and customization. Despite being a personal device, it can accommodate the most sophisticated experimental profiles that professional baristas might require. Additionally, it also comes with profiles that can be used by novices to replicate professional results and adjust to their personal preferences. Let’s see the development’s histories and dispute the detail specs if you have any ideas.
