Consistency Control - Overview (cont.)

In the “standby” mode the control board senses the temperature of the product in the barrel. The drive motor is cycled on time only. It will operate for 2 minutes ON then 18 minutes OFF as long as it is in “standby”. The com- pressor and drive motor are cycled independently for the barrel in the “standby” mode. Once the barrel thermister signals to the board, the board will start the compressor and the barrel solenoid valve will open as refrigeration is required. It will continue to run until satisfied. The plunger switch is disabled and the drive motor will not start when the plunger is opened. The hopper is still controlled by temperature. If the thermister signals a raise in temperature the compressor will start and the hopper solenoid valve will be opened. It will continue to run until satisfied.

In the “clean” mode the drive motor will run continuously. (The compressor will not run in the “clean” mode.) This is for emptying out product for cleaning purposes.

There are eleven (11) lights on the circuit board that indicate the following: (See Figure I)

BARREL (D1) - Illuminated when the freezing cylinder (barrel) has achieved the pre-set temperature in the "Stand- by" mode.

HOPPER (D2) - Illuminated when the hopper has achieved the pre-set temperature in the "Stand by" mode.

WASH (D3) - Illuminated when the mode switch is in the wash or "Clean" position.

FREEZE (D4) - Illuminated when the mode switch is in the "Freeze" mode.

DISPENSE (D5) - Illuminated when the dispensing valve is open calling for both the compressor and drive motor to operate.

GREEN CONSISTENCY (D6) - Off when the motor and compressor are off. Illuminated when the compressor and dasher are bringing product to preset consistency. Blinks as preset consistency is achieved and then goes out.

RED CONSISTENCY (D7) - Blinks as preset product consistency is approached. Glows steadily when preset consistency is achieved and then goes out.

COIL (D8) - Compressor contactor energized

COIL (D9) - Drive motor coil energized

COIL (D10) - Hopper refrigeration solenoid coil energized

COIL (D11) - Freezing cylinder refrigeration solenoid coil energized

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.
