Frequently Asked Questions - KMS-822MLH Hoshizaki

How do I clean the ice cream maker after use?

After each batch, turn off the machine and unplug it. Remove the dasher and scraper blades. Wash all removable parts with warm water and mild detergent. Rinse thoroughly and dry. Wipe down the cylinder with a damp cloth. Do not use abrasive cleaners. Refer to the manual for detailed cleaning instructions.

What type of ice cream mix should I use?

This machine is designed for commercial liquid ice cream mix with a fat content of 10-16%. Ensure the mix is pre-cooled to 4°C before pouring. Do not use homemade or hard ice cream mixes without proper adaptation.

How do I start the machine for a new batch?

Ensure the dasher is properly installed. Pour cooled mix into the hopper up to the fill line. Close the lid securely. Select the desired hardness and time settings. Press the start button. The machine will automatically stop when the batch is complete.

What should I do if the machine does not start?

Check that it is plugged in and the power switch is on. Verify the emergency stop button is not engaged. Inspect the fuse or circuit breaker. If it still does not start, contact Hoshizaki service.

How often should I replace the scraper blades?

Scraper blades should be inspected monthly. Under normal commercial use, replace them every 3-6 months or sooner if you notice reduced scraping or ice cream consistency issues. Use only genuine Hoshizaki blades.

What is the maximum capacity of the KMS-822MLH per batch?

The machine can produce up to 22 liters (approx. 5.8 gallons) of ice cream per batch. Actual yield depends on the mix and desired overrun.

Can I use the machine continuously?

The machine is designed for intermittent heavy use. Allow a 10-minute recovery time between batches to prevent compressor overload. Do not exceed 20 batches per day without adequate cooling breaks.

How do I adjust the hardness of the ice cream?

Use the digital control panel to adjust the hardness setting from 1 (soft) to 10 (hard). Higher settings increase freezing time and result in firmer texture. Refer to the manual for recommended settings.

What should I do if the ice cream is too icy or grainy?

Check that the mix is properly balanced (sugar and fat content). Ensure the dasher and scraper blades are in good condition. Avoid overfilling or using too low a hardness setting. Also verify the refrigeration system is working correctly.
