Match the juicer to the fruit and the volume. Citrus juicers, from electric reamers to automatic whole-fruit machines, handle oranges, lemons and limes; centrifugal juicers handle hard fruit and vegetables quickly; slow juicers and hydraulic cold presses handle leafy greens and bottled juice at a slower pace.
Key takeaways
- Citrus and non-citrus need different machines: an automatic citrus juicer will not juice carrots, and a centrifugal juicer is a poor tool for oranges.
- Size by peak demand, in glasses per hour or fruit per minute, and by how much fruit prep and loading the staff can keep up with.
- Pulp handling decides how long a juicer runs between stops: continuous pulp ejection suits volume, a basket that holds pulp suits short runs.
- Cleaning is daily and unavoidable, so count the parts that come off and check they fit the sink or dishwasher.
- Bottling juice to sell later raises food safety questions that fresh-squeezed service does not; check with your public health unit first.
Start with the fruit and the volume
The first split is citrus versus everything else. Citrus is juiced by pressing or reaming a halved or whole fruit, and the peel has to be kept out of the juice because its oils are bitter. Apples, carrots, beets, ginger, celery and greens are juiced by grinding or pressing the whole produce and separating the juice from the pulp. Few machines do both jobs well.
The second split is volume. A bar squeezing lemons and limes for cocktails, a café selling fresh orange juice through the morning, a hotel breakfast buffet and a juice bar built around green juice each point to a different machine. Estimate juice per day and, more importantly, per peak hour, then work out how many pieces of fruit that means.
- Cocktail citrus in small amounts: a manual lever press or a small electric citrus juicer
- Fresh orange juice in volume: an automatic-feed citrus juicer
- Hard fruit and vegetable juice made to order: a centrifugal juicer
- Leafy greens, wheatgrass and low-foam juice: a slow masticating juicer
- Bottled cold-pressed juice: a hydraulic press, with a food safety plan
Citrus juicers: manual, electric and automatic
Manual lever presses squeeze a halved fruit between a cone and a cup. They are quiet, need no power and suit a bar that juices limes and lemons for drinks. Electric citrus juicers spin a ribbed cone while the operator presses the half fruit down, often with a lever arm that does the pressing; they are faster and less tiring over a long shift.
Automatic-feed citrus juicers take whole fruit into a hopper, cut each piece and squeeze both halves, dropping the peel into a bin. Once loaded they run with little attention, which is why cafés, hotels and grocery stores use them, sometimes as a self-serve machine in front of customers. Makers such as Zummo and Zumoval build this type of machine.
Automatic juicers are rated by fruit per minute and accept a set range of fruit sizes, so check that range against the oranges, grapefruit, lemons or limes you buy; some models need a separate kit for small fruit. With any citrus juicer, look at how the machine keeps peel away from the juice and how peel and pulp are collected. Pressing into the pith adds bitterness, and a small waste bin that fills mid-rush stops the line.
Centrifugal juicers for hard fruit and vegetables
A centrifugal juicer grates produce against a fast-spinning disc and flings the pulp against a fine screen, so juice passes through and pulp stays behind. It is quick, handles apples, carrots, beets and ginger well, and a wide feed chute cuts prep time because fruit goes in whole or halved.
Commercial models differ mainly in how they handle pulp. Pulp-ejection models throw pulp out into a separate container and can run continuously; basket models hold the pulp inside the basket, which then needs emptying and cleaning, so they suit shorter runs. Check the size of the pulp container against a busy hour.
The trade-offs are foam, some separation in the glass and weak results with leafy greens, which tend to pass through with little juice extracted. Serve centrifugal juice promptly; it is made to be drunk, not stored.
Slow juicers and hydraulic cold presses
Slow or masticating juicers crush produce with a slowly turning auger and press the juice through a screen. They take more time per glass than a centrifugal machine but handle leafy greens and wheatgrass better and produce less foam. Feed chutes are often narrower, so plan on more cutting.
Hydraulic cold presses grind produce first, then press the pulp in filter bags under high pressure. They give a high yield and a smooth juice, which is why businesses that bottle cold-pressed juice use them, but they work in batches, need more labour and take longer to clean.
Cold-pressed describes the extraction method, not a shelf life. Juice bottled for later sale rather than poured to order raises food safety requirements that fresh service does not, and some producers use high-pressure processing to extend shelf life. If a bottled program is part of the plan, check with your local public health unit before choosing equipment.
Sizing, yield and prep
Capacity is only useful if staff can feed the machine. An automatic citrus juicer's hopper holds a limited number of fruit, so someone has to keep it topped up at peak. A centrifugal juicer depends on how much produce is washed, trimmed and ready beside it. Build the station around the prep, not just the juicer.
Yield depends on the fruit as much as the machine: variety, ripeness and size all change the juice per piece. Track it for a few weeks after a new juicer goes into service, because yield, more than the purchase price, decides what each glass costs.
- How many glasses in the busiest hour, and at what size?
- Which fruit and vegetables, and how large are they?
- Will staff juice to order, or batch ahead of service?
- Is the machine front of house, where noise and appearance matter, or in the kitchen?
- Where do the peel and pulp go, and who empties them?
Cleaning and hygiene
Juicers need a full clean at least daily, and a rinse between different produce where allergens or strong flavours are involved. Sugar and fruit residue sour quickly and attract fruit flies, and dried pulp in a screen is slow to remove, so clean while it is still wet.
Before buying, look at the parts that touch juice: how many there are, whether they come off without tools, whether they fit your sinks and whether the manufacturer allows them in a dishwasher. A juicer that takes a long time to strip down tends to be cleaned less thoroughly at the end of a long day.
Screens and filters are the parts that wear and clog. A soft brush clears them; a damaged screen lets pulp through and should be replaced. Keep spare screens and seals on hand if the juicer is central to your menu.
Power, delivery and ordering
Check the electrical rating on the spec sheet against the outlet where the juicer will sit. Most countertop juicers run on a standard 120-volt receptacle; confirm larger automatic machines on their spec sheet. Measure height as well as footprint, since hoppers and feed chutes add height under shelves.
Each Norpex product page says whether a juicer can be bought online by card or is priced on a quote. Inspect any freight delivery before signing, note damage on the delivery receipt and call Norpex the same day. Special-order and freight equipment is not returnable once delivered in good condition, so if the juicer you choose is either, confirm the model and its fruit-size range before ordering.
Common questions
What type of juicer suits fresh orange juice?
- For a few glasses at a time, an electric citrus juicer is enough. For steady volume, an automatic-feed citrus juicer cuts and squeezes whole oranges on its own and keeps the peel out of the juice.
Can a centrifugal juicer juice leafy greens?
- It can, but the yield is usually poor because greens pass through with little juice extracted. A slow masticating juicer or a hydraulic press handles kale, spinach and wheatgrass better.
What does cold-pressed juice mean?
- It means the juice was extracted by pressing rather than by a fast-spinning disc, either in a hydraulic press after grinding or in a slow masticating juicer. It describes the method and does not by itself make juice safe to store for long.
Can an automatic citrus juicer handle lemons and limes?
- Often, but each machine accepts a set range of fruit sizes. Check that range, and whether a kit for small fruit is needed, against the lemons and limes you actually buy.
How often does a commercial juicer need cleaning?
- At least once a day with the juice-contact parts removed, and more often in heavy use. Fruit residue sours quickly, so clean screens and baskets before the pulp dries.
