Computing Overrun (cont.)

3)Draw a heaping cup of frozen product that contains no air pockets. Note: Use a spatula or other device to help fill the cup completely. Avoid tamping the cup as this artificially reduces overrun.

4)Use a straight edge to scrape off excess product flush with the rim of the cup and weigh the cup.

5)Subtract the cup weight and use the overrun formula to determine overrun.

Weight of Weight of

Liquid Mix (Minus) Frozen Product x 100 = OVERRUN

Weight of Frozen Product

For Example:

If a full cup of liquid mix weighs 23 ounces (.652kg) and a full cup of frozen product weighs 15-1/2 ounces (.439kg), then:

Note: Several companies manufacture scales that automatically read out the overrun for one-pint samples. A scale of this type is a valuable tool and should be part of any well run operation. A trick is to place the empty cup on the scale and zero it out first; this will then automatically eliminate the weight of the cup from the calculation.

Overrun has a major impact on the size of the finished frozen portion. As the percentage of overrun (air in the frozen product) increases, the size of the finished portion also increases, yet the portion weight remains the same. For example, an increase from 25% to 50% overrun will yield a 20% larger portion. Customers equate size with perceived value so proper overrun will result in increased customer satisfaction. Experiment with carburetor settings to achieve optimum overrun and product quality with each mix. Some products such as Cappuccino taste better with low overrun. Experiment with different carburetor settings to find the ideal combination for each product.

Use of Stand-By Switch

The "STAND-BY" switch allows the operator to retain optimum product quality and conserve energy during extended non-draw periods. The "Stand-by" mode keeps the mix in the hopper at a safe storage temperature and allows the product in the freezing cylinder to return to a refrigerated liquid state. Switching back to "ON" quickly returns the product in the freezing cylinder to proper serving consistency.

At the start of the "STAND-BY" period:

1)Select the "STAND-BY" mode by moving the mode switch to the middle position. The front panel "STAND-BY" light will illuminate.

At the end of the "STAND-BY" period:

1)Turn the switch to the "FREEZE" position by moving the mode switch. The "FREEZE" light will illuminate.

2)When the freezer cycles off by reaching the desired temperatures you are ready to start serving.

IMPORTANT: The STAND-BY SWITCH should not be used in lieu of cleaning and sanitizing procedures specified by local regulatory agencies.

Mix Low Function

This model will sense when the mix is low in the hopper. The mix low light will illuminate continuously for 2 min- utes. After 2 minutes the light will begin to blink off and on for the next 8 minutes. The buzzer in the mix out circuit is 2 minutes off and 5 seconds (or 5 beeps) on for a total of 10 minutes. At the end of the 10-minute time the

5941, 5711, 5311, 5511 specifications

The Grindmaster 5711, 5941, 5311, and 5511 series of coffee grinders have emerged as prominent tools for coffee enthusiasts and professionals alike. Known for their durability and precision, these grinders offer a range of features that cater to various brewing methods and preferences.

At the heart of each model is a set of high-quality, stainless-steel burrs designed for consistent grind size. Burr grinders, as opposed to blade grinders, provide uniformity in particle size, which is essential for optimal extraction and flavor in coffee brewing. The Grindmaster series employs advanced grinding technology that minimizes heat transfer, preserving the delicate oils and aroma of the coffee beans during the grinding process.

One of the main features across these models is their user-friendly interface. They are equipped with intuitive controls, allowing users to easily adjust grind settings to achieve the desired coarseness or fineness. The 5711, for instance, is celebrated for its precision adjustment system, enabling users to fine-tune their grind settings for varying brewing methods, from espresso to French press.

Another noteworthy characteristic is the incorporation of an efficient motor that not only ensures smooth operation but also enhances durability for long-term use. These grinders operate quietly, making them suitable for environments where noise reduction is essential, such as coffee shops or homes with open layouts.

Safety and convenience features are also integral to the Grindmaster series. Most models include a safety lock to prevent operation while the grinder is being cleaned or adjusted. The removable grinding chamber makes it simple to clean and maintain the equipment, extending its lifespan and ensuring consistent quality.

The design of the Grindmaster grinders reflects both functionality and aesthetics. Their sleek and modern appearance fits seamlessly in both commercial settings and home kitchens. The robust construction withstands daily wear and tear, making them a reliable choice for frequent use.

In summary, the Grindmaster 5711, 5941, 5311, and 5511 models are distinguished by their advanced grinding technology, user-friendly design, durability, and aesthetic appeal. These grinders not only enhance the coffee brewing experience but also exemplify the commitment to quality that Grindmaster is known for in the specialty coffee industry. Whether for a coffee shop or a home barista setup, these grinders deliver the performance and precision required to unlock the full potential of coffee beans.
