Dry Curing Areas Curing Equalization and Aging

Frequency: Clean after product input and at the end of the designated cure or equalization period. To reduce mold growth in aging rooms, use filtered air or air conditioning with a filter.

Procedure:

1. Sweep floors.

2. Remove pallets and other portable storage equipment, and rinse cure and debris with 50 °C water.

3. Hose down vacated areas with 50 °C water.

4. Clean trolleys, trees, and other metal equipment used as outlined for wire pallets and metal containers.

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

6. Spray aging rooms once every 3 months with a synergized pyrethrin to reduce insect infestation. Follow application directions on the pesticide label.

G. Smokehouses

Frequency: After the end of each smoke period.

Procedure:

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

2. Apply an alkaline cleaning compound recommended for cleaning smokehouses through a centralized or portable foam system. A high-pressure unit may be used where foam cannot penetrate (Fig. 4).

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

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

5. Apply an iodophor or quaternary ammonium sanitizer, with a centralized or portable sanitizing unit, around the entry area to reduce air contamination.

H. Smokehouse Blower

Frequency: After each use cycle. Procedure:

Blades

1. Remove the blower housing access panel and drain plugs, soaking them with an alkaline solution.

2. Start the blower and flush with steam.

3. Stop the blower and flush again with water.

4. Repeat the operation until the equipment is clean.

Housing

1. Soak the inside of the plenum well, and wash the blower evolute wall with an alkaline cleaning solution.

2. Flush the housing with steam, then with water until it is clean.

3. Replace the drain plugs and access panel.

I. Smokehouse Steam Coils

Frequency: Depends on amount of use. Procedure:

Coils

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

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

Chamber around coils

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

2. Use 55°C water to flush the chamber wall clean.

3. Close the coil chamber access door.

J. Smokehouse Ducts and Nozzles

Frequency: Depends on amount of use. Procedure:

Outside ducts

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

2. Spray the inside surface with an alkaline cleaning solution.

3. Flush the outside ducts clean with 90 °C water or steam, followed by hot water. Repeat this exercise until the metal is exposed.

Inside return ducts

1. Mark the positions of the slide panels over the return ports so that the panels may be set back to their original openings for a balanced house.

2. Open the ports all the way and use as access doors for applying an alkaline cleaning solution to the ducts.

3. Use 90°C water for flushing the return ducts. Repeat this operation until the metal is exposed.

4. Reset the slide panels to the originally marked positions. Inside jet ducts

1. Open side access panels (or drop hinged panel, depending on type of house).

2. Soak the inside ducts and nozzles with a cleaning solution.

3. Use 90 °C water to flush these ducts clean. Repeat this operation until the metal is exposed.

4. Close the access panel (or hinged panel). Exhaust stack

1. Disassemble the stack (or open access panels).

2. Soak the stack interior with an alkaline cleaning solution.

3. Flush the stack with 90 °C water or steam, followed by hot water. Repeat this process until the metal is exposed, especially in the damper area.

4. Reassemble the stack (or close the access panels).

K. Smoke Generator

Frequency: Depends on amount of use. Procedure:

Filter

1. Soak the filter in an alkaline cleaning solution.

2. If mineralization has occurred, cut the frame apart, and clean the leaves individually. Reweld the frame after cleaning. Avoid warping.

Baffle and cascade chamber

1. Mechanically or brush manually the baffles (especially the edges) with a wire brush.

2. Scrape the edges of the cascade water outlet. Wash chamber

1. Disassemble the duct connecting the smoke generator to the house.

2. Remove soot and ash from the chamber below the filter.

3. Clean the duct and chamber surface until the metal is exposed.

L. Spiral Freezer

Frequency: After use.

Procedure: See instructions for specific equipment to be cleaned.

1. To minimize friction, regularly wash the spiral with a foaming cleanser.

2. When the track is warm, wipe with a cloth dampened with a cleaning compound solution. If the track is cold, a dry cloth may be used. Tie the cloth to the underside of the conveyor belt and let it be drawn through the spiral.

3. Defrosting the evaporator coil alone is insufficient for cleaning. Coils may appear clean, but grease, oils, salts, food adjuncts, and organic materials often remain hidden on internal surfaces. Therefore, it is necessary to clean and sanitize contaminated sites with warm water and a pH-balanced cleaning compound. Cleansing solutions typically include an etching agent, a degreaser, inhibitors, metal protectors, stabilizers, and water. A mildly alkaline cleanser is recommended for cleaning the evaporator coil.

4. If the freezer has been supplied with a recirculating CIP system, use a low-foaming detergent. Otherwise, use a high-foaming detergent. A chemical supplier should be consulted to determine the best chemical cleanser.
