The Black+Decker FP4100B is a good buy for a first food processor and for chopping, mixing and light prep in a small kitchen. It is a poor buy if shredding cheese, even slicing or smooth purees are the reason you are shopping.

You get a real 8-cup bowl, a stainless S-blade, a reversible slice/shred disc, two speeds plus pulse and a 2-year limited warranty, which is what the money goes toward. The specifications and limits below are those the manufacturer states, so nothing here claims speed, noise or cut quality beyond them.

What the Black+Decker FP4100B's Bowl, Wattage and Controls Mean for Your Cooking

The spec sheet describes a compact machine with a bowl big enough for everyday chopping and mixing.

Headline featureEasy Assembly

At 15.2 inches tall, the machine needs clearance under an upper cabinet. Measure the gap above the counter before you buy, because a processor that does not slide under the cabinet tends to stay in the cupboard.

What comes in the box, and what doesn't

The carton holds the motor base, the 8-cup work bowl, the lid, the food chute with its pusher, the stainless S-blade and the reversible slice/shred disc.

What is missing matters just as much. There is no dough blade, no dicing kit, no second or mini bowl, no storage lid, no whisk and no continuous-feed attachment. Many shoppers assume an 8-cup processor arrives with a dough blade, and this one does not, so knowing it before checkout avoids a return.

The bowl, blade and lid seat in a fixed order, and that is what the Easy Assembly label refers to. The interlock that enforces that order is also why the machine stays off when a piece is misaligned.

Where the Black+Decker FP4100B earns its place on your counter

Chopping

The S-blade is the heart of the machine, and the sheet lists chopping first. Onions, garlic, herbs, vegetables and semi-hard foods are its territory. Buyers on Amazon most often praise performance, and the summary of their reviews singles out chopping and mixing semi-hard items such as cheese and vegetables.

Mixing

Mixing is a listed function, so dressings, salsas, dips and batters that do not need a dough blade are within its documented range.

Slicing and shredding with the disc

The reversible disc slices on one side and shreds on the other, and the sheet lists both functions. Be clear about what the disc is: one fixed slice thickness and one shred size, with no adjustable slicer.

Easy assembly and cleaning

The headline feature holds up. Parts go together in one order, the removable parts are dishwasher-safe, and the base wipes clean. Buyers on Amazon often mention how quick it is to set up and how easy it is to clean.

Footprint

It takes up 9.7 inches of width and 9.4 inches of depth on the counter and weighs 5.8 lb, light enough to lift out of a cupboard and small enough to leave out.

Warranty

The 2-year limited warranty is real reassurance on a machine at the entry end of the market.

What the Black+Decker FP4100B cannot do well in daily cooking

One slice thickness, one shred size

There is no adjustable slicing, no dicing kit and no julienne disc. If those are on your list, this is not the machine for you.

No dough blade

The sheet does not include one, so the page promises no dough work beyond the mixing function the sheet lists.

The manual's do-not list

The use-and-care manual rules out coffee beans, bones, grains and hard spices. It also rules out anything frozen so hard a knife tip will not go in, warm meat, and liquids that are boiling rather than merely hot. Meat and cheese must be well chilled before slicing or shredding.

Fill guidance cuts the usable capacity

Chop at half to two-thirds full and never above the marked line. The usable chopping capacity therefore sits well under the 8-cup nominal figure, which is the most useful capacity fact on this page.

No published run limit or liquid maximum

The manufacturer does not publish a continuous-run limit for this model. The same goes for a separate liquid maximum: it is not stated, so it is not claimed.

Nuts and hard foods

The manual warns that nuts and hard foods may scratch the bowl's interior finish. That is cosmetic, but it is documented.

Plastic bowl

Plastic is the material the sheet specifies. Hand washing preserves its appearance, and the manual puts removable parts on the top rack only.

How to Get Better Results From Your Black+Decker FP4100B Every Time You Use It

The manual carries a short playbook that makes the machine behave better than its price suggests.

  • Speed map: puree on HIGH or LOW, chop on PULSE, slice on LOW, shred on LOW.
  • Disc work is LOW only, with light steady pressure on the pusher. Pushing harder does not speed it up.
  • Chill cheese and meat well before slicing or shredding.
  • Cut a flat base on round vegetables so they sit in the chute, and stand thin items upright.
  • Pulse for chopping so you can watch the texture, and do not fill past two-thirds.
  • Dry before wet when you have several jobs, and work in batches.
  • Cleaning: top rack only, hand-wash the plastic, do not soak the blade or disc, brush the blade's internal shaft, and wipe the base rather than immersing it.
  • Storage: the manual documents a nested arrangement with the bowl, blade, shaft set diagonally, inverted lid, pusher and disc stacked on top, which is how the machine earns its counter space back.

Troubleshooting from the manual

If it will not run, check the bowl and cover alignment, the plug and the breaker. If it will not slice or shred, the disc is probably installed the wrong way around or the food is unsuitable. If the cover will not close, the blade or disc is not seated.

Service

The manual says not to return the machine to the retailer. Use the manufacturer's warranty channel instead. The warranty is 2 years, limited, with replacement by a new or factory-refurbished unit, and it excludes commercial use, misuse and shipping.

The Black+Decker FP4100B is a capable, easy-to-live-with chopper and mixer with a real 8-cup bowl and a slice/shred disc. It is held back by one slice thickness, one shred size, no dough blade and a manual full of do-nots.

Buy it to chop, mix and prep in a small kitchen. Skip it if shredding, even slicing or smooth purees are why you are shopping.

Frequently asked questions

The interlock, the fill line and the disc orientation explain most of what surprises a new owner in the first week.

Will the Black+Decker FP4100B slide under my upper kitchen cabinets?

The Black+Decker FP4100B stands 15.2 inches tall, so measure the gap between the counter and the cabinet above before ordering. A processor that does not clear that space tends to end up stored in a cupboard rather than used.

Can the Black+Decker FP4100B grind coffee beans, grains or hard spices?

No. The 450 W motor and the S-blade are built for chopping and mixing, not for milling, so there is no grinding function to select and no grinding blade in the box. For coffee, grain or spice grinding, a dedicated grinder is the better tool.

Which settings should I use on the Black+Decker FP4100B for chopping, slicing and shredding?

Chop with the pulse setting so you can follow the texture, and run slicing and shredding on low speed only, pressing the pusher down lightly and steadily. Extra force on the pusher does not make disc work go faster.

Is the Black+Decker FP4100B a good choice for smooth purees?

Puree appears in the product title, but the lack of silky smooth results is one of the reasons we suggest skipping this model. Buyers who want velvety purees, even slices or grated cheese will be happier with a different machine.

What do buyers on Amazon say about how long the Black+Decker FP4100B lasts?

Opinions on Amazon are split on durability, with some owners expecting years of service and others reporting the machine giving out after only light use. The praise there centers on chopping and mixing semi-hard foods, fast setup and easy cleaning.
