Usage: Toboli Hydropress 51740, 51741 User Manual

Overview

The Hydropress 51740, 51741 is a water-powered fruit press for extracting juice, must, or wort from prepared fruit mash. It uses mains water pressure rather than electricity or manual force, making it suitable for home juice making, cider preparation, and small-batch wine production.

Choose model 51740 for smaller batches with its 20-liter basket, or model 51741 when a larger 40-liter basket is more suitable. Both versions require crushed or ground fruit rather than whole, halved, or quartered produce.

Detailed Description

The Hydropress 51740, 51741 presses fruit by filling an internal rubber membrane with water. As the membrane expands, it applies even pressure to the mash inside the press bag and basket. Juice passes through the basket and collects in the surrounding gutter before leaving through the outlet.

The main components are the vent valve and clamping nut, cover, rubber membrane, press or strainer basket, juice gutter, supporting frame, pressure gauge with water inlet and outlet, and juice outlet. The supplied press bag holds the mash and helps separate the extracted liquid from the pressed solids.

A fruit press is different from a centrifugal or cutting juicer. The press is intended to preserve seeds and process fruit mash gradually. Apples, pears, and similar firm fruit should be crushed before pressing. Soft grapes, berries, currants, and stone fruit generally do not need grinding because their pulp is already soft; grinding them can release bitter compounds from the seeds.

Safety

• Use water pressure only. Never connect compressed air, because an air-filled membrane can create an explosion hazard.
• Before pressing, operate the vent valve until trapped air has escaped and water is visible. This prevents an air pocket from forming inside the membrane.
• Keep children and people with limited physical, sensory, or mental capabilities away from the operating area. The press is not intended for unsupervised use by children.
• Keep hands and loose clothing away from rotating or moving equipment used to prepare the mash.
• Protect the rubber membrane from direct sunlight and sharp objects.
• Secure the press on a stable, level surface so it cannot slide or tip during operation.
• Do not apply excessive force, and operate the equipment only when all parts are in good condition.
• Keep plastic bags, foam, and other packaging away from children because they can cause suffocation.

Suitable Fruit Preparation

Use only clean, healthy, ripe fruit. Remove unripe, overripe, rotten, moldy, or badly damaged pieces before processing. Windfall bruises can be acceptable when they show no signs of rot. Wash the fruit with drinking water before making the mash.

Firm fruit such as apples, pears, and quinces should be crushed to create a coarse mash. A mash that is too fine can become purée, preventing juice from draining freely. A mash that is too coarse may reduce juice yield. Remove stems whenever possible because they may contribute bitter flavors.

Hard vegetables and hard, unripe fruit are not suitable for a typical fruit mill or this pressing process unless they have first been prepared with equipment designed for them.

Setup and Operation

Initial Setup

1. Wash the press components with clean water before the first use. Do not use abrasive or aggressive cleaning products.
2. Rinse the press bag thoroughly.
3. Attach the feet to the base frame using the supplied screws if the unit arrives partially assembled.
4. Position the press on a level, stable surface near a suitable water drain and water connection.
5. Place a clean container beneath the juice outlet.

Loading the Press

1. Fit the press basket onto the frame with the supporting legs correctly positioned.
2. Place the press bag inside the basket and fold the lower portion into place.
3. Open the top of the bag around the basket rim and fold the edge outward to make filling easier.
4. Add the prepared fruit mash. The basket does not need to be completely full; partial loads can also be pressed.
5. Fold the press bag over the mash and place the cover on the basket.
6. Fit the washer over the spindle and tighten the clamping nut.
7. Install the splash guard and position the collection container beneath the outlet.

Pressing Procedure

1. Connect the water supply to the 3/4-inch inlet and open the water tap gradually.
2. Press the vent valve so air leaves the membrane. Continue until the air has escaped and water emerges.
3. Monitor the pressure gauge while the membrane expands and juice flows through the basket into the gutter.
4. Keep the pressure at or below the 3-bar maximum. A pressure reducer is recommended when the supply network can exceed this level.
5. Increase pressure slowly rather than opening the tap fully at once. Gradual pressure gives the juice more time to drain through the mash.
6. When the target pressure is reached, close the water tap and wait until juice flow has nearly stopped.
7. Use the drain valve to release water from the membrane. Operate the upper valve as needed so air can enter the membrane while it deflates.
8. Wait until no more water flows out and the press is fully depressurized.
9. Loosen the clamping nut, remove the cover and splash guard, and lift out the press bag containing the spent fruit material.

Cleaning and Maintenance

Clean the Hydropress 51740, 51741 immediately after each use so juice and fruit residue do not dry onto the components. Rinse the press with clear water and clean it with a sponge or similarly gentle material.

• Do not use wire brushes, abrasive cleaners, or other harsh cleaning materials.
• Rinse the press bag thoroughly with water. It may also be washed in a washing machine without detergent at a maximum temperature of 30°C.
• Allow components to dry before storage.
• Store the press in a dry place protected from light.
• Keep the rubber membrane away from prolonged sunlight, which can damage the material.
• Inspect the membrane, valves, connections, press bag, and frame before the next use.

Troubleshooting

Little or no juice is produced

• Check that whole fruit has not been loaded. Reprocess apples, pears, and similar firm produce into a coarse mash.
• Check whether the mash is too fine and has formed a purée that blocks drainage.
• Check whether the mash is too coarse to release juice efficiently.
• Use ripe, sound fruit and remove rotten pieces, stems, and unsuitable material.
• Increase pressure gradually and allow sufficient time for juice to pass through the mash.

Pressure does not build correctly

• Confirm that the water supply is connected to the correct inlet.
• Operate the vent valve until trapped air has been removed from the membrane.
• Check that the water tap is open and that the connections are secure.
• Read the pressure gauge and never exceed 3 bar.
• Stop using the press if the membrane, valve, hose connection, or frame appears damaged.

Water remains inside the membrane after pressing

• Close the water supply.
• Open the drain valve to release the water.
• Use the upper valve to allow air into the membrane while it deflates.
• Do not loosen the cover or clamping nut until the press has fully depressurized.

Pros and Cons

Pros

• Water-powered operation does not require electricity.
• Gradual pressure control supports efficient juice extraction.
• Two basket capacities accommodate smaller and larger batches.
• The pressure gauge helps monitor the pressing process.
• The press bag simplifies separation of juice and spent mash.

Cons

• Fruit must be properly crushed or mashed before pressing.
• Whole or poorly prepared fruit will not produce effective results.
• The maximum working pressure is limited to 3 bar.
• The press requires access to a suitable water connection and drain.
• The membrane needs protection from sharp objects and prolonged sunlight.
