Section 2: Operation

MAINTENANCE PARTSTROUBLESHOOTING

OPERATIONINTRODUCTION

C. Cleaning Disassembled Parts

Disassembled parts require complete cleaning,

sanitizing and air drying before assembling. Local and

state health codes will dictate the procedure required.

Some state health codes require a four sink process

(pre-wash, wash, rinse, sanitize, air dry), while others

require a three sink process (without the pre-wash

step). The following procedures are a general guideline

only. Consult your local and state health codes for the

procedures required in your location.

Rinse all parts with clean 90° to 110°F (32°C to 43°C)

water. Then place all parts in a sanitizing solution for at

least 1 minute, then remove and let air dry completely

before assembling in machine.

C.2

Be sure to use the brushes that shipped

with the machine to properly clean the

parts.

NOTE

Place all parts in 90° to 110°F

(32°C to 43°C) mild detergent

water and wash thoroughly.

Use the brushes that shipped

with the machine to clean all

holes in the front door, ﬂights,

mix pickup assembly, etc.

C.1

D. Cleaning the Machine

Using a detergent solution

and the large barrel brush

provided, clean the freezing

cylinder by dipping the brush

in the solution and brushing

the inside of the freezing

cylinder.

Make sure to thoroughly clean the rear seal surface

on the inside of the freezing cylinder.

Section 2: Operation

E. Assembling Machine

Total Blend or equivalent must be used

when lubrication of machine parts is

speciﬁed.

The USDA and FDA require that lubricants

used on food processing equipment must

be certiﬁed for this use. Use lubricants

only in accordance with the manufacturer’s

instructions.

NOTE

Stoelting recommends allowing the parts

to air dry before assembling.

NOTE

Install the rear seal o-ring onto the auger. Lubricate

the outside of the o-ring with a generous amount of

sanitary lubricant.

E.1

The exterior of the machine should be kept clean at

all times to preserve the luster of the stainless steel.

A high grade of stainless steel has been used on the

machine to ease cleanup. To remove spilled or dried

mix, wash the exterior with 90° to 110°F (32°C to 43°C)

mild detergent water and wipe dry.

Do not use highly abrasive materials, as they will mar

the ﬁnish. A mild alkaline cleaner is recommended.

Use a soft cloth or sponge to apply the cleaner. For

best results, wipe with the grain of the steel.

D.4

Wrap the brush in a clean cloth and thoroughly dry

the freezing cylinder.

D.2

Remove the drain tray from the

front of the machine. Remove

the drip tray from the front

panel. Clean and replace the

trays.
