INTRODUCTION

This equipment will store up-to six pounds of whole bean coffee in the hopper and grind it to a preset grind and amount into an awaiting funnel and filter from most commercial drip coffee brewers. The equipment is only for indoor use on a sturdy counter or shelf. Adequate space must be available above the grinder to raise the lids when adding beans. Use only with whole bean coffee.

The grind is preset at the factory to drip specifications as set forth by the United States Department of Com- merce and adopted by the Coffee Brewing Center of the Pan American Coffee Bureau. Adjustments may be made to alter both the amount and grind from the factory setting.

G9WD-RH specifications

The Bunn G9WD-RH is a premier commercial coffee grinder designed for high-demand environments, such as cafes, restaurants, and coffee shops. Renowned for its efficiency, durability, and consistency, this grinder is an essential piece of equipment for any establishment that values quality coffee.

One of the standout features of the Bunn G9WD-RH is its powerful grinding capabilities. Equipped with a 1.1 horsepower motor, it can easily handle high volumes of coffee beans, making it ideal for busy locations. This grinder operates at a speed of approximately 3,600 RPM, allowing for quick and uniform grinding, which is crucial for achieving optimal flavor extraction.

The G9WD-RH utilizes a unique patented design for its burrs. The burrs are made of high-quality stainless steel and provide a precise grind size that can be easily adjusted. This adjustment can be made on the fly to suit various brewing methods, from espresso to French press, allowing baristas to tailor their grind to the specific needs of each beverage. The grinder has an intuitive control panel that enables users to control grind time accurately, ensuring that the desired amount of coffee is ground each time.

Another notable technology integrated into the Bunn G9WD-RH is its Smart Hopper. This innovative feature allows the grinder to hold up to 1 pound of coffee beans while also providing a built-in grinder activation that stops the grinding process once the hopper is empty. This not only prevents waste but also enhances the overall efficiency of the grinding process.

Durability is a hallmark of the Bunn G9WD-RH, constructed with robust materials that can withstand the rigors of a commercial environment. The unit features a heavy-duty metal housing and a shock-absorbent design that minimizes vibrations, reducing wear and tear over time.

Moreover, the Bunn G9WD-RH is designed for easy maintenance. The grinding chamber can be easily accessed for cleaning, ensuring that the grinder remains sanitary, which is vital for maintaining the quality of the coffee.

In summary, the Bunn G9WD-RH coffee grinder is a reliable and efficient machine that combines advanced technology with practical features, making it an invaluable asset for any coffee-focused business. Its high-performance capabilities paired with user-friendly operations ensure that it stands out in the competitive market of commercial coffee grinders.
