7.0 MIXING CAPACITY.

MIXER CAPACITY

The Mixer Capacity Chart is a guide for controlling the batch sizes in your formulations. The capacities listed take into account the amount of product, which can be contained in the various sized bowls. The listed capacities are the maximum recommended batch sizes. If the combined weight of the bowl and ingredients is greater than 25kg a bowl truck must be used. Recipes for dough used to establish the batch sizes in the Mixer Capacity Chart are listed below:

Do not exceed the specified mix quantity. The maximum capacity of the mixer bowls are:

HL800 (full size): 75.7 liters

HL1400 (full size): 132.5 liters

HEAVY BREAD MEDIUM PIZZA RAISED DONUT

INGREDIENT DOUGH DOUGH DOUGH

Flour 100.0% 100.0% 100.0%

Water 55.0 50.0 65.0

Yeast 2.0 1.0 5.0

Salt 2.5 1.5 2.5

Sugar 5.0 - 0 - 15.0

Shortening 5.0 - 0 - 15.0

Oil -0- 2.0 -0-

Non-Fat Dry Milk 6.0 - 0 - 8.0

Total 175.5% 154.5% 210.5%

The ingredient percentages are based on a flour content of 100 percent to simplify using the recipes to make various sized batches and compute the moisture absorption ratio.

The flour used in the recipes is hard wheat flour, enriched and bleached. It contains 11 to 12 percent protein content and 12 percent moisture content. Flour, which has lower moisture content, will decrease the moisture absorption, cause difficulty in proper gluten hydration, and make a heavier load on your mixer. Flours containing high quality protein, such as high gluten flour, result in dough, which can be very difficult to mix. If high gluten flour is used, reduce the batch quantity noted on the Mixer Capacity Chart by 10 percent to prevent overloading of the mixer.

The temperature of the water used in the recipes is 18°C to 23.0°C. Cooler water temperatures will cause the dough to be harder to mix. If you plan to mix doughs using cold water, the batch size may need to be reduced by 15 to 20%. Also considered and noted on the Mixer Capacity Chart is the moisture absorption ratio (AR). This is the ratio of the weight of water to the weight of flour expressed as a percentage.

AR = weight of water ÷ weight of flour * 100%

The absorption ratio gives an indication of the relative "heaviness" or "wetness" of a batch. In fact, the capacities listed on the Mixer Capacity Chart for the products listed below are based on the following absorption ratios:

PRODUCT ABSORPTION RATIO

Heavy Bread Dough 55%

Medium Bread Dough 60%

Light Bread Dough 65%

Thin Pizza Dough 40%

Medium Pizza Dough 50%

Thick Pizza Dough 60%

Raised Donut Dough 65%

Whole Wheat Dough 70%

When mixing any of the above products with an absorption ratio lower than listed, decrease the batch size proportionately to assure efficient mixing of the product and thus eliminate the possibility of overloading your mixer. For example: An HL800 mixer has a thin pizza dough capacity of 38.6 kg at first speed based on an AR of 40% according to the Mixer Capacity Chart. If the batch has an AR of 30%, reduce the batch size to compensate for the difference. Compute the size of the reduction as follows:

1. Divide the AR of the batch to be mixed by the AR listed on the Mixer

Capacity Chart.

2. Multiply the rated batch size by the percentage obtained in step 1. The result is the maximum batch size of the HL800 mixer for pizza dough with 30% AR.

30% Actual AR

= 75%

40% Rated AR

38.6 kg. Rated Batch Size x 75%

for 30% AR Dough

Another factor often overlooked is the ability of your mixer to operate at a different speed. To prevent overloading, use the recommended mix speed from the Mixer Capacity Chart. Because of the toughness of a 40% AR thin pizza dough, a maximum mix time of 5 minutes on first speed is recommended. To mix 50% AR or lower doughs on second speed on model HL800 and HL1400, reduce the batch size by 50%.

The speed of the mixer, length of mix time, room temperature and ingredient temperatures all affect dough temperature. To achieve the desired final dough temperature, you may need to adjust the water temperature.

For batch size capacities on other bread doughs not mentioned on the Mixer Capacity Chart, follow the batch size recommendation for listed bread dough with a similar absorption ratio.

8.0 MIXER AGITATORS.

AGITATORS AND THEIR USES

Hobart Quick Release ™ agitators are available for the Legacy mixers and for the type of product that is being mixed.

The B Flat Beater is a multi-purpose agitator used for mashing potatoes or other vegetables, and mixing cakes, batters or icings. It is also used in industrial applications for any product requiring a creaming or rubbing action and uniform dispersion of ingredients. Use first speed for starting most operations; medium speed for finishing.

The D Wire Whip is designed for maximum blending of air into light products. Uses include: whipping cream, beating egg whites, mixing very light icings, meringues and all similar applications. The D Wire Whip is most commonly used in third and fourth speed.

The ED Dough Hook is used for mixing most bread, roll and pizza dough, which require folding, and stretching action for best development. These agitators are suitable for use on all yeast raised doughs and should be operated in first, second or third speed.

The C Wing Whip is used for whipping material that is too heavy for the D Wire Whip. The heavy frame permits its use for light creaming and beating. It is often used for whipping or blending potatoes, butter, and mayonnaise or light icings. It is generally used in first and second speed for whipping heavy products like potatoes or in third or fourth speed for light products such as mayonnaise or icings.

The P Pastry Knife combines shortening with flour, and is ideal for light pastry shells (patty shells), flaky pie dough and similar mixes. The cutting action of the knife practically eliminates rubbing and allows delicate ingredients to be combined without over development. The P Pastry Knife is suitable for stirring operations in low speeds and for fast cutting operations in medium speeds. You should not use the P Pastry Knife at high speed if you want the pastry to have a flaky texture.

The I Wire Whip makes sponge cakes and mixes marshmallow and icing for heavy whipping.

8.2

Splash Covers and Bowl Extension Rings provide a means for minimizing dust emissions and reducing splashing for certain mixes at higher speeds. Splash covers fit under the Bowl Guard. The stainless steel Bowl Extension Ring is also available. Splash Covers and Bowl Extensions, while convenient accessories, should not be used to increase the mixing capacity beyond the recommended maximum. The best functioning of Hobart mixers requires room at the top of the bowl for aeration and manipulation. Follow the Hobart Mixer Capacity Chart of the best quality of mix. Splash Covers on larger mixers have a smaller diameter opening at the top due to their inverted cone shape. Overloading the mixer while a splash cover is in use reduces aeration because of restriction in the area where air enters the batch.

SPLASH COVER AND BOWL EXTENSION RING

8.3 BOWL SCRAPER ATTACHMENT.

The mixer Bowl Scraper Attachment is available for the HL800/HL1400 Mixer full and half size bowls. This attachment scrapes the sides of the bowl as the agitator rotates to re-introduce material into the mixture. The scraper must only be used with the whip or flat beater agitators.

8.4 BOWL TRUCK.

When maneuvering or lifting a bowl and contents with a total weight in excess of 25 kg a bowl truck must be used.

Bowl Trucks or dollies provide convenience, save time, and reduce effort in handling large batches. Remove heavy batches of dough or batter from the mixer by unlocking the bowl and lowering on to the Bowl Truck. Carefully roll the truck away to make room for the next batch. Move the material to another location where it is to be used, or refrigerate between mixing and further processing. Bowl Trucks save time, reduce handling, and improve workflow. These are all valuable tools in a work place.

9.0 CLEANING.

CLEANING NEW MIXER BOWLS AND ACCESSORIES

Before using the first time, thoroughly wash new mixer bowls and agitators (beaters, whips, dough hooks and pastry knives). Wash in hot water and a mild detergent solution,

rinsing with either a mild soda or vinegar solution, and thoroughly rinse with clear water. Also follow this cleaning procedure for bowls and agitators before whipping egg whites or whole eggs.

9.1 CLEANING AFTER USE.

After use, clean the mixing bowl, agitators and attachment with hot water, using a suitable non-abrasive detergent and soft bristle brush. (Flushing the bowl with hot water immediately after use will ease the cleaning).

Note: Do not clean the aluminium agitators in a dishwasher.

Clean the mixer with a hot damp cloth; thoroughly wipe the bowl support arms and all exterior surfaces. The guard should be cleaned as follows.

Cleaning the guard.

The guard should be cleaned at the end of each day. Once the guard is removed (see Section 6.12 page 21) it can be cleaned with hot water, using a suitable non-abrasive detergent and soft bristle brush. The stainless steel splashguard can be wiped off and/or washed with a cloth or sponge them using warm soapy water. Rinse with clean water and dry with a clean cloth.
