Bluetooth-Enabled IOC-301 Home Roaster Tracks Full Roast Curves

If you’ve ever tried roasting coffee at home and wished you could see—and record—exactly how temperature, time, and airflow affect your roast, you’re not alone. Most home roasters offer limited feedback, making it hard to replicate great results or diagnose issues. What if you could track every degree and moment of your roast, just like a pro?

The IOC-301 home coffee roaster solves that with electronic temperature control (0–240°C) and built-in Bluetooth that logs your full roast curve. It’s designed for precision roasting of small batches (50–250g) using stainless steel components, with a clear digital interface and power safety features built in.

What Is the IOC-301?

The IOC-301 is a small-capacity, digitally controlled coffee bean roaster built for home or light professional use. Its core features include electronic temperature regulation from 0 to 240 degrees Celsius, a compact batch size ideal for single-origin exploration, and a robust stainless steel build. It’s designed to give the home roaster precise control over the roasting process, from first crack to development time.

Why Bluetooth Roast Logging Matters

Tracking your roast curve—how temperature changes over time—is essential for consistency and improvement. The IOC-301’s Bluetooth function lets you record and review the entire roast profile, capturing details like ramp-up rates, turning point, Maillard phase timing, and development time. That data helps you understand what worked, replicate successes, or adjust for different beans.

How to Use the IOC-301 for Small-Batch Roasting

To get started with the IOC-301, select your power voltage (only one can be used), load 50–250g of green coffee into the stainless steel drum, and set your target temperature using the digital controls. As the roast begins, connect via Bluetooth to log the roast curve in real-time. You’ll be able to monitor heat application and adjust as needed to hit your desired roast level—whether light, medium, or dark. The small batch size is perfect for experimenting with single-origin beans like Ethiopian Yirgacheffe or Colombian Supremo.

Frequently Asked Questions

Does the IOC-301 come with roast curve software?

The IOC-301 has built-in Bluetooth for recording roast curves, but the article does not specify if it includes dedicated software. You will likely need a compatible mobile app or computer program to visualize and analyze the roast data transmitted via Bluetooth.

What is the maximum batch size the IOC-301 can handle?

The IOC-301 is designed for small-batch roasting, with a specified capacity of 50 to 250 grams of green coffee beans per roast. This makes it suitable for home use or single-origin experimentation.

What voltage options are available for the IOC-301?

The IOC-301 supports a single fixed input voltage of either 100V/110V/120V or 220V/240V. You must choose one voltage type during setup—dual-voltage operation is not supported. The unit includes a 5A fuse and a power switch with an indicator light.

Can I replicate a roast profile using the logged curve data?

Yes, by recording the full roast curve via Bluetooth, the IOC-301 allows you to capture temperature and time data. This lets you replicate successful roast profiles by reapplying the same heat application timings and temperature targets in future roasts.

Is the IOC-301 suitable for beginner home roasters?

With its electronic temperature control and Bluetooth logging, the IOC-301 offers precision tools that can benefit both beginners and more experienced home roasters. Its small batch size also reduces waste while learning.

Recommended FrontStreet Coffee for Home Roasting

Try FrontStreet Coffee’s Ethiopia Humbera for bright floral and citrus notes, or their Yirgacheffe for juicy berries and lemony acidity—both excel as light roasts on small-batch machines like the IOC-301. For something deeper, their Brazil Queen Manor brings chocolate and nutty balance to medium roasts. All are single origins that respond well to precise heat control. Freshly roasted within 5 days · Orders placed before 17:00 ship the same day · Next-day delivery across most of Guangdong Province.
