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
21
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:
HL600 (full size): 56.8 litres
HL600 (half size): 37.9 litres
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:
22
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 HL600 mixer has a
thin pizza dough capacity of 18.2 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 HL600 mixer for pizza dough with
30% AR.
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. Second speed should never be
used on 50% AR or lower products except on model HL662.
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.

AGITATORS AND ATTACHMENTS.
Attachments for the attachment hub, agitators and accessories are detailed in the
following section.
8.1
AGITATORS AND THEIR USES
Hobart Quick Release ™ agitators are available for the Legacy mixers and for
the type of product that is being mixed.
MIXER AGITATORS.
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.
25
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 USING THE ATTACHMENT FACILITY.
MEAT CHOPPER ATTACHMENT
The Meat Chopper Attachment allows you to prepare many additional foods with your
Hobart mixer. A plate having 4-mm holes comes with the Meat Chopper Attachment
when shipped from the factory. Other plates are available with hole sizes 2, 5, 6, 10, 13,
16 and 18 mm for fine to coarse chopping. The results are the same as produced by
Hobart commercial meat choppers. Operate Meat Chopper Attachments in second
speed on the HL600 or dedicated speed on the HL662 mixer. The feed pan should be
kept in place in the cylinder for ease of feeding. Cut meat into strips and feed it into the
chopper using the feed stomper only as needed. Substances that could become packed
tight in the chopper like breadcrumbs are not recommended. If material in the cylinder
stalls the mixer, push the STOP button at once. DO NOT attempt to restart at a slower
speed. Remove the adjusting ring, knife, plate and worm and clear the obstruction.
Always keep the drain hole on both the Attachment Hub and Meat Chopper clean, clear
and free of obstruction.
26
8.3 SPLASH COVER AND BOWL EXTENSION RING
Splash Covers and Bowl Extension Rings provide a means for minimising 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.
8.4 BOWL SCRAPER ATTACHMENT.
The mixer Bowl Scraper Attachment is available for the HL600 Mixer full and half size
bowls. This attachment scrapes the sides of the bowl as the agitator rotates to reintroduce material into the mixture. The scraper must only be used with the whip or flat
beater agitators.
8.5 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.
27
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.
