Each part is meticulously designed to work in unison for safe and efficient pressure canning. It’s essential to familiarize yourself with these components and their functions for optimal performance and safety.

Operating Instructions

Pressure canning involves creating a sealed environment within the canner to reach a specific temperature that safely eliminates harmful bacteria in food. This process requires careful adherence to instructions to ensure optimal results and safety. Here’s a general overview of pressure canning using your Mirro 22-quart canner⁚

1. Prepare your jars and lids⁚ Thoroughly wash and sterilize the jars and lids. Ensure lids are free of any debris or damage.
2. Pack the jars with food⁚ Follow specific recipes for packing jars with the desired food, leaving proper headspace for processing.
3. Process the jars⁚ Place the jars in the canner, ensuring they are evenly spaced for proper heat distribution. Add water to the canner, reaching the level specified in your recipe or manual.
4. Heat the canner⁚ Bring the water to a boil and maintain a consistent pressure level throughout the processing time.
5. Cool the jars⁚ After processing, carefully remove the canner from the heat source and allow it to cool naturally. Do not open the canner until the pressure gauge reads zero.
6. Remove and seal⁚ Remove the jars from the canner and ensure lids are securely sealed.

Detailed instructions for specific recipes and foods are available in the Mirro pressure canner manual and recipe book. Always follow those instructions closely to ensure safe and successful pressure canning.

Filling the Canner

The correct water level in your Mirro 22-quart pressure canner is crucial for achieving the proper pressure and temperature during processing. Here’s a step-by-step guide to filling your canner⁚

1. Position the rack⁚ Place the jar rack in the bottom of the canner, ensuring it is stable and level.
2. Add water⁚ Pour hot water into the canner, reaching a level of 2 to 3 inches above the tops of the jars. Using hot water helps to speed up the heating process.
3. Check the water level⁚ Ensure the water level is sufficient to cover the jars by at least 1 inch. If necessary, add more hot water to maintain the appropriate level.
4. Avoid overfilling⁚ Do not overfill the canner. The water level should never exceed the maximum fill line indicated on the canner. Overfilling can lead to pressure buildup and potential safety hazards.

Always consult your Mirro pressure canner manual and specific recipe instructions for the exact water level required for each food item;

Adding Jars

Once you have filled the canner with the appropriate amount of hot water, you can begin adding your jars. Carefully and securely placing the jars in the canner is essential to ensure proper processing and prevent any accidents. Here’s how to add jars to your Mirro 22-quart pressure canner⁚

1. Prepare the jars⁚ Ensure the jars are clean and free of any debris. Use a jar lifter to carefully place the jars on the rack within the canner.
2. Space the jars⁚ Leave a small space between each jar to allow for proper heat circulation. It is alright if the sides of the jars touch each other.
3. Avoid overcrowding⁚ Do not overcrowd the canner. Overcrowding can hinder heat transfer and affect the processing time. Consult your recipe and canner manual for the recommended number of jars for your 22-quart canner.
4. Secure the lid⁚ Once all the jars are in place, securely fasten the lid of the canner. Ensure the lid is properly sealed to maintain pressure during processing.

Following these steps will ensure your jars are safely and efficiently placed within the canner, ready for the processing stage.

Heating the Canner

After you have securely placed your jars in the canner, it is time to heat the canner to reach the desired pressure level. This step is crucial for ensuring proper food preservation and safety. Here’s how to heat your Mirro 22-quart pressure canner⁚

1. Turn on the heat⁚ Place the canner on a stovetop burner. Set the burner to high heat and allow the canner to heat up.
2. Watch for steam⁚ As the canner heats, steam will begin to vent from the vent tube. This is normal and indicates that the canner is reaching the desired temperature.
3. Adjust the heat⁚ Once steam is venting steadily, reduce the heat to maintain a steady flow of steam. This will help to maintain the desired pressure level.
4. Maintain pressure⁚ The pressure will gradually rise as the canner continues to heat. Keep a close eye on the pressure gauge and adjust the heat as needed to maintain the recommended pressure for your recipe.
5. Process time⁚ Once the canner has reached the desired pressure, set a timer for the processing time specified in your recipe. Continue to maintain the pressure throughout the processing time.

Heating the canner correctly is essential for successful pressure canning. Always follow the instructions in your recipe and canner manual carefully for safe and effective food preservation.

Maintaining Pressure

Maintaining the correct pressure within the canner is critical for successful pressure canning. The pressure ensures that the temperature inside the jars reaches the necessary level to kill bacteria and safely preserve your food. Here’s how to maintain pressure in your Mirro 22-quart pressure canner⁚

1. Monitor the pressure gauge⁚ Keep a close eye on the pressure gauge throughout the processing time. The gauge will indicate the pressure inside the canner in pounds per square inch (PSI).
2. Adjust heat as needed⁚ If the pressure drops below the recommended level, increase the heat slightly to bring it back up. If the pressure rises above the recommended level, reduce the heat to lower the pressure.
3. Maintain a steady flow of steam⁚ Ensure that steam is continuously venting from the vent tube. This indicates that the pressure is being maintained within the canner.
4. Avoid opening the canner⁚ Do not open the canner during the processing time. Opening the canner will release pressure and disrupt the processing cycle, potentially compromising the safety of your food.
5. Complete the processing time⁚ Allow the canner to maintain pressure for the full processing time specified in your recipe. This ensures that the food has been properly preserved.

Maintaining the correct pressure is essential for safe and effective pressure canning. Always follow the instructions in your recipe and canner manual carefully.
