Principles of Food Sanitation

5. Sanitize cleaned areas according to
   manufacturer requirements with a qua-
   ternary ammonium compound for its
   residual effect.


6. Spray aging rooms once every 3 months
   with a synergized pyrethrin. Follow the
   directions on the label. Sulfuryl fluoride,
   an alternative to methyl bromide that is
   being phased out, is a non-flammable,
   odorless, colorless and noncorrosive, that
   can leave a residue in the area treated and
   the products being stored.

Smokehouses

FREQUENCY After the end of each
smoke period.
PROCEDURE

1. Pick up large debris and place in a
   receptacle.


2. Apply an alkaline cleaning compound
   recommended for cleaning smokehouses
   through a centralized or portable foam
   system. Figure 17–4 illustrates a unit
   used for cleaning smokehouses.


3. Rinse the area within 20 to 30 minutes
   after cleaning compound application.
   Start at the ceiling and walls, and work
   all extraneous matter down to the floor
   drain.


4. Inspect all areas, and touch up where
   needed.


5. Apply a quaternary ammonium sani-
   tizer with a sanitizing unit at the entry
   area to reduce air contamination.

Smokehouse Blower

FREQUENCYAfter each use cycle.

PROCEDURE

Blades

1. Remove the blower housing access
   panel and drain plugs; soak with an
   alkaline solution.


2. Start the blower and flush with steam.
   3. Stop the blower and flush again with
   water. Repeat the operation until the
   equipment is clean.
   Housing
   
   
   1. Soak the inside of the plenum well, and
      wash the blower evolute wall with the
      alkaline cleaning solution.
   
   
   2. Flush the housing with steam, then
      with water. Repeat until the housing is
      clean.
   
   
   3. Replace drain plugs and access panel.
   
   
   
   

Smokehouse Steam Coils

FREQUENCYDepends on amount of use.

PROCEDURE

Coils

1. Open the coil chamber access door and
   soak with an alkaline cleaning solution,
   brushing vigorously.


2. Flush the coils with steam, then with
   water. Repeat until the metal is shining.

Chamber around Coils

1. Brush the cleaning solution on the
   inside of the chamber walls.


2. Use 55ºC water to flush the chamber
   wall clean.


3. Close the coil chamber access door.

Smokehouse Ducts and Nozzles

FREQUENCYDepends on amount of use.

PROCEDURE

Outside Ducts

1. Remove the ductwork at the back of
   the house and remove carbon deposits.
   Disassembly is not necessary if the
   ducts have access panels.


2. Spray the inside surface with an alka-
   line cleaning solution.


3. Flush the outside ducts clean with 90ºC
   water or steam, followed by hot water
   until the metal is exposed.
