Optimum Juicer FAQs

Below are frequently asked questions about the Optimum Juicers.

  • What are the dimensions of the juicer
    • Optimum 400 and 500 are 20x19x45 cm and weigh 6.5 kg. The juicing chute is 3.5x5.5 cm
    • Optimum 600 is 50x25x20 cm and weighs 7.34kg. The juicing chute is 7.5 cm around
    • Optimum 700 is 24x17x43 and weighs 7.6 kg. The juicing chute is 8 cm around
  • Why should I juice?

    Fresh juice, especially vegetable based juices, helps meet the minimum daily servings of fruit and vegetables in your daily nutrition plan. Juicing allows the consumption of fruits and vegetables that are not otherwise enjoyable to eat in large quantities.

    Nutrient absorption from juicing improves longevity. A large percentage of the population has a limited ability to absorb nutrients from fruits and vegetables due to impaired digestion due to age, allergies or even continued unhealthy eating habits. Premade juices are usually pasteurized and therefore contain minimal nutrients. Fresh, homemade juices carry live nutrients and minerals direct to the blood stream in less than 20 minutes.

    Furthermore, green juices are highly alkalising, which helps improve energy, digestion and mental clarity. Juicing alkaline foods can also help to maintain the body’s natural pH allowing clearer skin, overall health and wellbeing.

  • What is the difference between a centrifugal and masticating juicer?

    In contrast to the tearing extraction and high speeds of centrifugal juicers, cold press – or masticating – juicers function at lower speeds to gently compress fruit and vegetables and ‘press’ out the juice.

    Nutritional tests between a cold press and centrifugal juicer revealed that cold press juicers extract up to 42% more vitamin C, up to 60% more vitamin A and yield between 35 - 50% more juice.

    Test results from Michelson Laboratories,Inc., Korean Food Research Institute (KRFI), and internal labs.

  • What the difference between blending and juicing?

    The main difference between blending and juicing is what you can make in each appliance. Mainly, the difference between cold-pressed juices created in juicers and smoothies, which are created in high-speed blenders.

    When you juice, you can drink the nutrients of fruits and vegetables in one glass, since the pulp and fiber is left behind. Your digestive system gets a break because there are no solids to break down.

    Smoothies leave nothing behind – you drink the whole food. You can load smoothies up with yummy things like almond butter for healthy fats. Smoothies are more rich and filling. While smoothies are easier on your digestion than solid foods, they are not as cleansing or detoxing as juices.

    In both the blender and juicer, you can also make nut butters, ice creams and nut milks. High speed blenders can also be used for food preparation, chopping and grinding, hot soups and making dough.

  • Can I make juice in bulk and store it?

    The biggest concern for keeping juices fresh is oxidation. During the juicing process, fruits and vegetables are broken open and their enzymes and other nutrients are released. When exposed to air, juice becomes oxidized and less nutritionally stable. Here are some tips to reduce oxidation and minimize exposure to air:

    1. Fill a mason jar all the way to the top with juice.  The goal is no air inside the jar.
    2. Seal the lid tightly. 
    3. Mark the outside of the jar with the ingredients and the date (and perhaps the time) the juice was made.
    4. Store in the refrigerator for up to 24 hours.
  • Besides juice, what else can I make in the juicer?
  • How do I make nut milk?

    Raw almonds are recommended as the best nut to make milks with. All nuts should be soaked for 12 – 24 hours and then rinsed thoroughly before feeding into the juicer simultaneously with water. We found that 250 gms of dried nuts create 1-litre of creamy milk. For a creamier consistency, add more nuts.

    Use only raw nuts and avoid any roasted or cooked nuts. Other nuts worth trying, either in combination with almonds or alone, are brazils, macadamias, hazelnuts, walnuts and pecans. We also recommend adding agave syrup, maple syrup, cacao nibs, dates (with stones removed), apple juice, cinnamon as sweeteners and flavour enhancers to your favourite nut milk. See below for recommended soaking ad dehydrating times:

    • Almonds: soak for 12 hours, dehydrate for 15 hours
    • Brazil nuts: soak for 12 hours, dehydrate for 18 hours
    • Cashews: soak for 6 hours, dehydrate for 15 hours
    • Hazelnuts: soak for 8 hours, dehydrate for 12 hours
    • Macadamia nuts: soak for 4 hours, dehydrate for 12 hours
    • Pecans: soak for 8 hours, dehydrate for 12 hours
    • Pine nut: soak for 8 hours, dehydrate for 12 hours
    • Walnuts: soak for 8 hours, dehydrate for 12 hours

  • Do I need to use the juicer tap?

    The juicer tap offers some extra features in your Optimum Juicer. When it is correctly in place, you can start juicing with the tap closed. This allows a mixing function that lets you juice your ingredients and fill the juice bowl, up to 300ml, with your favourite mixture. Once your food is juiced, you simply open the tap and release the mixed juice into your glass, reducing any frothing. With the automatic pulp ejection, you can still juice continuously until the bowl is full, let out the juice and then continue juicing. The mixing function also improves the results when making nut milk.

  • My juicer is stuck and I cannot disassemble it. What do I do?

    Occasionally, slow juicers will bind up with clogged juice. Here is the recommended method for dislodging the juicing assembly are as follows:

    • With the unit completely assembled, press the reverse button for 1 second to loosen the auger in the bowl. This often resolves the issue, but if not continue to the next step.
    • Keep the entire juicing assembly in one piece (do not remove the hopper) and attempt to remove the juicing assembly as one whole unit. This process gives greater leverage and will cause no damage to the machine.
    • If the above two steps fail, keep the juicer assembled entirely and press and hold the reverse button. With the machine on, use your other hand wiggle the whole juicing assembly from side to side and pull the whole assembly up off the base of the juicer. Holding the reverse button ensures safety since you can release it at anytime to instantly cut power. The unit will automatically power off when the magnetic connection built into the hopper is separated also.
    • If the three above steps fail, send the unit to us for inspection under warranty. Please note that any damaged occurred while following the above steps will be covered under warranty. Should you not be able to disassemble the juicer please contact our 24/7 Warranty & Support team at www.froothiesupport.com.


    To ensure the cold press juicer does not get clogged again, follow the tips below:

      • Do not press or shove food into the juicer. Cold press juicers do not have a spinning blade or dizzying shredding, so no force is required. Instead, simply let your food fall into the "chewing auger." Forcing more food into the chute can cause too much vegetable mass to clog in the auger, resulting in pulp overflowing into your juice, or the juicer becoming blocked.

        When juicing grass, coriander, parsley, kale, spinach or other leafy green, feed small, 3 cm-long amounts at a time. This ensures the waste can easily come out of the waste chute. You do not need to "clump" the ingredients into a ball.

        For large leafy, stringy or fibrous vegetables, remove the leaf from the stem, cut both leaves and stems into 3-5 cm lengths and feed through gently, letting the auger pull the ingredients into the juicer, using the tamper only gently if required.


      • Alternate between juicer and more fibrous fruits and vegetables.Alternate between juicier ingredients like apples, carrots, cucumber and citrus fruits and the more fibrous ingredients like kale and spinach, celery and wheatgrass. We also suggest saving carrot for last, as this helps push out the last of the pulp.


      • Insert red plug correctly. Make sure the red rubber plug/tongue/stopper on the underside of the juicing bowl is correctly inserted into its slot. This part is removable to assist with cleaning, but often not reinserted correctly. It acts as a pressure point to ensure pulp ejects from the waste chute. The plug should not be pushed in with any force, and should sit comfortably a third of the way.
  • I’m juicing citrus fruit. Do I need to peel them?

    We do suggest peeling citrus fruits, such as lemon and oranges, as the peel has quite a bitter taste. When juiced with the peels this bitter taste will transfer to the juice.

  • My Juicer won’t start? What do I do?

    Please ensure that the juicer is assembled correctly. As a safety feature the juicers will not start if they have not been assembled in the correct manner. If the juicer is assembled correctly and will not start please contact our 24/7 Warranty & Support team atwww.froothiesupport.com
