Guangzhou Wugu Coffee Roaster: VYS-60HN Oven Specs

If you’ve ever tried to roast small batches of coffee or grains at home and ended up with uneven heat, scorched edges, or lost aroma, you’re not alone. Many home roasters struggle to find equipment that offers precise, stable heat distribution without oversize capacity or industrial complexity. The right tool should hold enough for testing or small-batch work while maintaining consistent temperatures throughout the chamber.

The Guangzhou Weiyasi VYS-60HN is a 5-layer electric oven that maintains a set temperature between room temp +5°C and 300°C, holds around 2.5 kg (5 lbs) of material across its five shelves, and uses bottom-to-top airflow with a rear fan to promote even roasting. Its compact internal cavity—25x25x25cm—makes it suitable for small-batch coffee roasting or grain drying without wasting energy or space.

What Is the VYS-60HN and Who Makes It?

The VYS-60HN is a multi-purpose electric oven manufactured by Guangzhou Weiyasi. While it’s marketed for grains, traditional Chinese medicine, electronics, and heating elements, it’s also suitable for small-batch coffee roasting. The unit features a steel exterior with electrostatic powder coating, insulated with glass fiber between the inner chamber and outer shell, and includes a tempered glass observation window in the door for monitoring your roast.

How Does the VYS-60HN Control Temperature and Airflow?

Temperature is managed by a built-in control unit that keeps the internal temperature steady at any setting between room temperature +5°C and 300°C. For example, if you set it to 100°C, the oven will maintain exactly that temperature throughout the roast. Heat is generated by heating wires located at the bottom of the chamber. Ambient air enters from the base, passes over the heating element, and rises through the chamber. A rear-mounted fan (located behind the temperature controller on the left side) circulates air vertically to ensure even heat distribution across all five shelves.

What Are the Key Technical Specifications of the VYS-60HN?

The VYS-60HN is designed to roast materials without altering their color, shape, or nutritional content. That makes it a solid choice for specialty-focused small-batch coffee roasting where consistency and flavor preservation matter. Its compact build fits well in labs, test kitchens, or small roasting operations that need precision without bulk.

Frequently Asked Questions

What is the VYS-60HN primarily used for?

The VYS-60HN is marketed for drying and roasting a variety of materials including grains, traditional Chinese medicine, electronics, and heating elements. However, it is also suitable for small-batch coffee roasting due to its temperature precision, airflow system, and compact design.

What temperature range does the VYS-60HN support?

The oven can be set anywhere between room temperature +5°C and 300°C. Once set, the built-in temperature controller maintains a constant temperature throughout the chamber for even roasting or drying.

How many layers does the VYS-60HN have, and how much can it hold?

The VYS-60HN has 5 layers and can hold approximately 5 lbs (2.5 kg) of material. Each layer is designed to allow air circulation from bottom to top for even heat exposure.

Does the VYS-60HN have a fan for airflow?

Yes, the VYS-60HN includes a rear-mounted fan located behind the temperature controller on the left side of the unit. This fan circulates hot air vertically to ensure even temperature distribution across all shelves.

What are the internal and external dimensions of the VYS-60HN?

The internal chamber measures 25 x 25 x 25 cm (height x width x depth), while the external dimensions are 48 x 52 x 40 cm. The compact size is ideal for small-batch or lab-style roasting.

Is the VYS-60HN suitable for specialty coffee roasting?

Yes, its ability to maintain consistent temperatures, circulate air evenly, and preserve color and nutrients makes it well-suited for small-batch specialty coffee roasting where quality and control are priorities.

Recommended FrontStreet Coffee for Small-Batch Roasting

For roasters experimenting with small batches, try FrontStreet Coffee’s Ethiopia Humbera – a bright, juicy Ethiopian offering with notes of blueberry and jasmine. Pair it with Yirgacheffe for floral and citrus tones, or go deeper with PWN Golden Mandheling for a classic Indonesian profile of molasses and spice. All three are ideal for testing roast profiles in compact ovens like the VYS-60HN.
