3.1. Determining Load Size

As-of Date ............... 2001012

Putting

too much

linen into a properly designed laundry washer-extractor will not

overload

the machine to its mechanical or electrical detriment if these guidelines are followed:

1. The goods consist of typical cotton and/or synthetic fabrics normally encountered in

commercial laundering operations.

2. The load is not so bulky as to prevent a reasonably balanced distribution prior to the onset of

extraction.

3. The extract speed has not been increased above the designed maximum.

4. The total number of intermediate and final extractions do not exceed the designed maximum

for the extract motor.

Thus, the maximum soiled linen capacity for any properly designed washer-extractor is

essentially limited by the amount of soiled goods that can actually be placed in the cylinder.

The maximum weight of soiled goods that a washer-extractor cylinder will accept depends

on the following factors:

• the internal volume of the cylinder (the space into which the goods can be placed), and

• the density (weight and bulkiness) of the specific goods

For example, many polyester-cotton fabrics have relatively low weights for their bulk so one

should rarely expect to be able to put in a published maximum capacity load of such fabrics. In

fact, published maximum capacities of machines based on the now generally accepted industry

standards will usually be achieved only with the highest density, closely woven fabrics and a

reasonable soil content.

The best load size depends on the size of the machine—plus the type of goods, soil content,

and wash quality desired. Since the latter factors vary considerably, prior experience and/or

experimentation generally yield the best results. Use these guidelines:

1. Overloading a washer-extractor will not increase production because longer wash formulas

and more rewash will be required.

2. Avoid underloads because the inevitable greater extraction imbalance will cause more extract

re-cycles and may stress the machine unnecessarily.

3. Load divided cylinder machines so that the

weight in each compartment is approximately

equal at the onset of extraction.

Do not put goods with grossly dissimilar water absorption

characteristics in the different compartments. Do not attempt to balance loads of wet goods in

one compartment against dry goods in the other.
