How Does the Mehu-Liisa Steam Juicer Work?

How the MehuLiisa works

1. Lid and Steam Basket

The steam basket or colander of the Mehu-Liisa steam juicer can hold up to 11 dry liters (11.6 dry quarts) of berries or vegetables. The high dome of the lid allows the user to pile produce beyond the rim of the basket. As soon as processing starts, the contents of the basket start to settle down right away, allowing the lid to come to rest on the rim of the basket. The lid fits snug but not too tight to allow excess steam to escape during processing. This keeps the juice from becoming diluted by condensation returning to the kettle. The convex bottom of the basket, with its central shield of nonperforated metal, directs juice into the kettle below without dripping down the steam tube into the water pan below.

2. Juice Kettle and Hose

The juice kettle contains the steam funnel through which steam from the water pan flows up to surround the fruit in the steam basket. The steam heats the fruit and the fruit cell walls burst, releasing juice. The kettle catches the juice as it runs down from the fruit in the steam basket. It has a 4 liter capacity which is enough to hold the juice from a full basket of most fruit without risk of the juice flowing down the funnel into the water pan. For very juicy fruit like grapes, blueberries, and plums, it is important to draw off juice at the halfway point of processing (approx. 1/2 hour of steaming) to keep the juice from running into the water pan below. The hot juice is drawn out of the kettle via the food-grade surgical plastic tube into sanitized canning jars. Lids are put in place and juice is then water bathed or steam canned according to USDA recommendations.

3. Water Pan

The water pan has a 4 liter capacity and holds more than enough water for a single batch of steam processing when the water is held at a steady, not furious, boil. As with all cookware, care must be taken to keep the water pan from boiling dry as this can lead to damage to the pan and stove. The best way to avoid this is to remain in the kitchen when processing and to use a timer set at 15 – 30 minute intervals. Hi heat sources like outside propane camp cook stoves must be regulated very closely to avoid boiling dry. The water pan can also be used as a soup pot or roaster. The lid is designed to fit the water pan nicely.

    Does juicing draw out all the nutrients in the fruit ? Or is there still good stuff in the pulp ?

      Diane,

      Yes, most of the nutrients are in the juice after processing, but the fiber in the pulp is of high nutritional value. My favorite way of using the pulp is to make fruit butters and spreads. This works best with firmer fruits like cherries, blueberries, stone fruit, apples, and pears. After processing (no need to go more than 45 minutes for any fruit), I put the pulp through a food mill to remove seeds, skin, etc. Then add back some juice and follow recipes for fruit spreads (I use Pomona Pectin recipes) or make fruit butter in my crock pot. Here’s a recipe from the blog that you can tailor to your needs: https://mehuliisa.com/2017/11/21/apple-ginger-butter-with-the-mehu-liisa-steam-juicer/

      Let me know if you have other questions. Have fun!

      Take care,
      Daniel
