Product Preparation; Paf- Powder Mix Set-Up (Brix Ratio) - Bunn ULTRA Technical Training Manual

Product Preparation

Whether liquid concentrate or granulated powder, all product must be thoroughly mixed BEFORE adding it to the
hoppers.
For best results with granita-type products, use only products with an apparent brix of 12 or higher. Some products
may work with an apparent brix as low as 9. Your experimentation with other products will be the best guide in this
area.
Keep the pre-mixed liquid product refrigerated. This reduces cooling/freezing time in the dispenser.
Keep the hoppers topped-off during peak serving periods. Add pre-mixed liquid product as it is dispensed. This re-
duces the cooling/freezing time and assures you of always having product ready to dispense.
Keep the product level in the hoppers higher than the auger. If the auger is exposed, air will become entrapped in the
mixture resulting in a clouded foamy consistency.
You may find it beneficial to turn down the ice controls to keep the ice granules from growing too large.
Some products freeze at a lower temperature than others. You may notice frost or ice on the hoppers. This is normal
and should not be a concern.
Humidity in the air may cause sweating on the outside surfaces of the hoppers. This is to be expected and should
not be a concern. The drip trays beneath the hoppers will capture this and cause it to flow to the lower drip tray for
disposal.
Some noises are to be expected during normal operation of the dispenser. By becoming familiar with the noises
made during normal operation, you will be better able to listen for problems.
PAF- Powder Mix Set-Up (Brix Ratio)
When using the PAF with a new powdered granita mix, follow the procedure outlined below to adjust the PAF to pro-
duce the correct brix ratio according to the product manufacture.
Step 1: Determine the mix ratio of powdered granita mix. Convert the recipe so that it is expressed in terms of weight
units [grams (g), dry ounces (oz), or pounds (lbs)] of powdered granita mix to fluid ounces (fl.oz.) of water [1 gallon
gal) = 128 fl.oz.; 1 liter (l)= 33.8 fl.oz.].
Step 2: The delivery rate of the water ingredient is factory preset to 1 fl.oz. per second. Therefore, it is only neces-
sary to adjust the delivery rate of the powdered granita mix.
Step 3: Place the PAF on top of a fully assembled ULTRA taking care to align the PAF guide rails over the rollers on
the platform guide rails.
Step 4: Connect the PAF power cord to the outlet located on the ULTRA auger motor cover.
Step 5: Attach a flexible water line to the .25" flare fitting on the back panel of the PAF.
Step 6: Ensure the ULTRA is powered ON and the Day/Night setting is set to Day.
Step 7: Pull the PAF fully forward on its support rails.
Step 8: Pull the slide gate closed on the PAF product hopper elbow and remove the product hopper from the PAF.
