The Coffee Roasting Machine is a state-of-the-art innovation designed to automate and
enhance the coffee roasting process. Developed with precision and efficiency in mind,
this machine caters to the growing demand for high-quality roasted coffee in Nepal and
beyond. Its primary function is to transform green coffee beans into roasted beans,
unlocking the rich flavors and aromas essential for brewing. It is equipped with advanced
temperature control sensors, allowing operators to achieve precise roast profiles ranging
from light to dark, depending on customer preferences. The user-friendly interface
provides real-time data on temperature, roast duration, and bean development stages,
making it accessible to both novice and expert roasters.
The machine is designed to handle small to medium batch sizes, making it ideal for local
coffee producers, cafes, and cooperatives looking to scale their operations. Its durable
construction, energy efficiency, and ease of maintenance further enhance its appeal as a
practical and reliable solution for Nepal’s burgeoning coffee industry. By offering greater
control over the roasting process, this machine empowers coffee producers to deliver
consistently high-quality coffee, contributing to the growth of Nepal's coffee sector and
positioning local producers in competitive domestic and international markets.

The story of Nepal’s coffee roasting innovation began with the challenges faced by local
farmers in achieving the quality needed to match international standards. Traditionally,
coffee roasting in Nepal relied on simple methods such as wok roasting over wood fires
or pan roasting, practices that were deeply rooted in the culture but inefficient and
inconsistent. These methods often left beans unevenly roasted, with unpredictable flavors
that limited their marketability and prevented farmers from fully capitalizing on Nepal’s
unique coffee profile.
Recognizing this challenge, the National Innovation Center (NIC) stepped in with a
vision to transform the coffee roasting process. Rajesh Limbu, a seasoned mechanic with
a passion for solving real-world problems, led the initiative. Working alongside skilled
mechanics like Dajangu Sherpa and Am Bahadur Roka, they set out to develop a modern
coffee roasting machine that could bring consistency and quality to Nepali coffee.
The team's journey was one of relentless innovation. They studied traditional roasting
methods and identified the gaps—uneven heat distribution and lack of control over
temperature were the main culprits. Inspired by the need to empower local farmers and
unlock Nepal's potential in specialty coffee markets, they began designing a machine that
could address these issues.
Their innovation wasn't just about creating a machine; it was about creating
opportunities. The modern coffee roasting machine they developed allowed farmers to
roast beans with precision, ensuring even roasting and bringing out the beans' best flavors
and aromas. This breakthrough not only enhanced the quality of the coffee but also
opened doors for Nepali coffee to compete globally. By introducing this technology, the
NIC team turned a longstanding challenge into an opportunity for growth, empowering
farmers, improving livelihoods, and putting Nepali coffee on the map as a premium
product.

The objective of the coffee roasting machine is to provide a sophisticated, efficient, and
precise platform for transforming green coffee beans into high-quality, aromatic roasted
beans. Historically, coffee roasting has faced challenges such as inconsistent roast
profiles, inefficient processes, safety concerns, and high maintenance requirements. To
address these issues, this machine aims to achieve uniform roasting by ensuring all coffee
beans are evenly roasted through consistent stirring and precise temperature control. This
results in a balanced and flavorful roast profile. Efficiency and productivity are also key
objectives, with the machine designed to minimize downtime and maximize throughput
by automating key processes such as bean loading and cooling. This enhances overall
operational efficiency and productivity. Safety and reliability are prioritized by
incorporating features such as a gas control valve and an efficient exhaust system By
achieving these objectives, the coffee roasting machine aims to deliver consistently high-
quality roasted coffee beans, meeting the demands of both commercial and specialty
coffee producers while overcoming historical challenges in the coffee roasting industry.
