Ice machine for a bakery (bake shop)

A bakery is mixer ice plus, sometimes, a cafe counter. Dough work wants ice that melts into the recipe water and pulls heat out of the bowl. Iced lattes want a drink cube. Putting both jobs on one 38 lb crescent leftover, or shopping Howe’s industrial 1,000 lb flaker for a 12 lb morning mix, is how the bench buys bagged ice — or how a 24″ cabinet sits unused next to a 40-quart mixer.

This is a planning page from published application factors and current OEM sheets. It is not a dealer quote, not a review score, and not a health-code opinion. Confirm electrical, plumbing, clearance, and sanitation with the people who inspect the building.

Published bakery factors

Foodservice charts almost never give a “pounds per guest” bakery line. Dough ice is a recipe / flour-weight problem. Front-of-house drinks, if you have a counter, are a cafe line. Those are dealer/OEM rules of thumb, not a manufacturer warranty and not a lab measurement.

The VenueIce sizing table has cafe, restaurant, and office rows. It does not have a bakery guest factor, because the dealer charts we opened do not publish one. Use Coast’s 10–20% of flour weight for mixer ice. Use Atlantic’s 0.35–0.6 lb/drink (or Kitchen Spot’s 2.5 lb/person if the counter is a smoothie bar) for glasses. Add Kitchen Spot’s +20% when you want their published reserve. Do not fold the cafe counter into the flour line.

Why bakeries buy ice at all

Mixer friction heats dough. Howe, Ice Systems, North Star, and Coast all say the same job: keep final dough temperature in range so fermentation does not run away.

• Ice as part of the recipe water. Ice Systems: where the recipe allows, flake ice replaces a controlled share of mixer water. When it melts, hydration stays the same and the mix is colder. British Baker (BakeTran / Stan Cauvain) says chilled water is often required in warm weather, and flaked ice is often added when chilled water alone cannot hit the target.
• Melt is the cooling. Howe: the phase change is 144 BTU/lb. Chilled water is only 1 BTU/lb/°F. That is why a bakery that already has a water chiller still looks at flake in summer.
• Shape matters for the bowl. Howe, Ice Systems, and North Star prefer flake over cube or crushed ice: thin flakes spread, melt fast, and are written as gentler on mixer tools. GoFoodservice’s ice-type page says bakers use flake to keep dough cold. We did not find a current OEM sheet that tells a bake shop to prefer cube ice for dough work.
• Drinks are a second plant. Atlantic: if you need two ice forms, specify two systems. Kitchen Spot’s “multiple units” paragraph is the same idea (flake at the display, cube at the bar). A bakery cafe is that split: flake at the mixer, cube or cubelet at the pass.

Cube, half-dice, crescent, and nugget math for glasses lives on best undercounter for a cafe and cube vs half-dice vs nugget vs flake. Do not scoop drink cubes into a spiral mixer because the cafe machine is closer.

Worked neighborhood bake shop (mixer only)

Same peak-day method as the sizing page: count the load, pick a published factor, add the reserve the source uses.

Morning bread and pastry, no cafe counter. Operator-counted 80 lb of flour on the peak bake (weigh the bags; we did not invent your formula).

• Coast 10% of flour: 80 × 0.10 = 8 lb
• Coast 20% of flour: 80 × 0.20 = 16 lb
• Kitchen Spot +20% on that ice: about 10–19 lb in the bowls that morning

That 8–19 lb is the mix, not a 24-hour restaurant rating. Ice Systems says to size from batches per hour and mixers running together. If those 80 lb of flour go through one mixer before the ovens light, the bin has to hold the pull. A Hoshizaki F-330BAK stores 80 lb. The 24-hour “up to 331 lb” column is far above this shop. Howe’s 1,000 lb/day bakery starting plant is a different building.

If chilled water already hits target dough temperature, Ice Systems treats flake as the extra control when water alone cannot. We do not invent a “you must buy a flaker” rule.

Worked bake shop with a cafe counter

Same 80 lb flour morning, plus an iced-drink pass.

• Mixer (Coast 10–20%): 8–16 lb flake
• 80 iced drinks (Atlantic cafe 0.5 lb midpoint of 0.35–0.6): 40 lb cube
• Kitchen Spot +20% on the drink line: 48 lb
• Peak-day subtotal if you wrongly add them on one machine: about 56–64 lb of different ice

Atlantic and Kitchen Spot both tell you to split ice types. The flake cabinet feeds the mixer. The cube cabinet feeds the glasses. A Hoshizaki KM-81BAK stores 38 lb. A Hoshizaki KM-161BAK stores 78 lb. A Manitowoc UYF-0140A stores 90 lb. The 38 lb bin covers a 40–48 lb drink line only if the rush is slow enough for make during the window — see the cafe lunch math on the cafe guide. Do not copy Kitchen Spot’s 2.5 lb/person smoothie line onto an iced-latte bakery unless the counter is actually blending.

Worked production bake (still a commercial undercounter)

Peak day 400 lb of flour, still one or two mixers, still a retail shop.

• Coast 10%: 40 lb
• Coast 20%: 80 lb
• Kitchen Spot +20%: about 48–96 lb

The F-330BAK built-in bin is 80 lb. A 96 lb Coast-and-reserve morning is at or past that bin if it all leaves before the cabinet catches up. Hoshizaki’s current F-330 HTML page does not print a 90/70 production cell, so we do not invent hourly make. On stored ice alone, 80 lb covers a 40–80 lb mix if the bin is actually full when the first batch drops.

Holiday Ice’s 500 lb/day “small-scale” industrial flake and Howe’s 1,000 lb/day bakery floor are the next class up. Ice Systems’ first industrial band on the UK bakery page is 600–1,500 kg per 24 running hours (about 1,300–3,300 lb). Those plants are not in this directory.

The morning mix window

A 24-hour rating is not a bucket. Bakery ice is taken when the mixer runs — often before the shop opens — not as 4 lb every hour for 24 hours.

Take the 400 lb-flour Coast 20% morning (80 lb before reserve):

• Mix pull: about 80 lb in a short window
• F-330BAK stored ice: 80 lb. The current HTML page does not print 90/70 production, so we do not invent lb/hour of make. On stored ice alone the bin matches an 80 lb pull only if it is full and scoopable.
• Add a cafe rush on the same flake cabinet and the 80 lb bin is the constraint, not the 331 lb headline.

That is already the sizing page bin-first sentence. Kitchen Spot also says ice in a bakery room will not make the 70/50 brochure number.

Kitchen / bakery heat derate

Manufacturer “up to” numbers are a 70°F air / 50°F water comparison point. The machine that lives next to deck ovens and a proofer is not in that room.

• Kitchen Spot: if the machine is in a 90° kitchen or bakery with ~70° water, “you can expect less ice production by as much as 15% or more.” Ice-O-Matic, Scotsman, and Manitowoc “all publish output for various models at different ambient temperatures.”
• GoFoodservice: listed capacities are under ideal conditions; “actual output may be 10–15% lower in hot environments.”
• Atlantic: a hot, poorly ventilated room is not the DOE test. Do not pick a machine whose advertised capacity exactly equals peak demand with no margin.

Cited 70/50 → 90/70 drops on sheets we opened (air-cooled unless noted):

Compare the 90/70 column to the peak-day target when the sheet has one. An oven alley in August is closer to Kitchen Spot’s bakery sentence than to a 70/50 lab.

Air-cooled cabinets also dump heat into that alley. F-330BAK heat rejection is 3,400 BTU/h on the current product page. KM-161BAK is 2,800 BTU/h. KM-81BAK is 1,800 BTU/h. AM-50BAK is 1,400 BTU/h. NEO U-140 family sheet: 2,150 average / 2,600 peak. Those BTUs become bakery cooling load on an air-cooled cabinet. See air-cooled vs water-cooled.

Form factor: compact undercounter vs industrial flake

Retail bake shops in this directory’s size class usually want a 115 V self-contained cabinet. Industrial bakeries are a different catalog.

Undercounter flake is one 115 V cabinet with a built-in bin. Hoshizaki’s current F-330BAK page writes salad bars, seafood displays, and “other applications requiring long-lasting, sanitary ice.” It does not print “bakery” on that HTML. The bakery flake sentences we opened are on Howe, Ice Systems, North Star, GoFoodservice, and Coast. The F-330 is the flake cabinet already in this directory that fits a tight bake-off hole (24″ × 26″ × 39″, front-in / front-out). It is not Howe’s 1,000 lb plant.

Undercounter cube is the cafe counter. HVACDirect calls undercounter machines “ideal for offices, cafes, and smaller establishments with constrained space.” The KM-81BAK and KM-161BAK pages say small bars, hotel lobbies, and office break rooms. Use them for drinks, not as a substitute for flake in the bowl. Form-factor background: undercounter vs modular vs countertop.

Industrial flake (Howe, Ice Systems, North Star, Holiday Ice) is a production-floor machine, often with a process bin and a cart to the mixer. Ice Systems warns that several small commercial cabinets can be an operational risk when ice is recipe-critical. That sentence is about factories. It is not a reason to skip a 115 V flaker in a 1,200 ft² bake shop.

Cube ice (crescent, half-dice, medium cube) is the usual glass ice. Cubelet / nugget is chewable soda ice. Flake is the dough and display ice. See cube vs half-dice vs nugget vs flake.

Current flake undercounter (OEM sheets)

Figures are manufacturer ratings. Full citations live on each directory page. Street prices omitted.

Hoshizaki’s 4HC-H filter page (already noted on the F-330 directory page) says that filter is not recommended for flakers. Use the filter the F-330 sheet specifies. See filters and descalers.

A cubelet sibling F-330BAK-C is 300 lb on the 08/28/25 spec PDF already cited on that directory page. Treat it as the cubelet variant of the same cabinet, not as dough flake.

Current cube undercounters for a cafe counter (OEM sheets)

These cabinets are drink tools. They are the same shortlist as the cafe and office pages.

AM-50BAK, C-80BAK, KM-81BAK, KM-161BAK, and F-330BAK are R290 on those current Hoshizaki pages.

Power, drain, air, filter (bake-off realism)

Many bakery ice rooms are a hot hole: one circuit, a mop sink, a deck oven eight feet away, and a louver someone boxed in. Read the sheet before the quote.

• 115 V cord-and-plug on the compact cabinets above (F-330, KM-81, KM-161, UYF-0140, AM-50, C-80). Two cabinets on one bake-off circuit is an electrician question.
• Drain. Gravity to a nearby floor drain or sink tail if the sheet’s fall and fitting work (F-330 / KM-81 / KM-161: 3/4″ FPT on those current pages; AM-50 / C-80: 1/2″ FPT; NEO family sheet: 1/2″ FPT ice-making drain and 1/2″ FPT bin drain). Hoshizaki accessory HS-5061 is the listed drain pump on AM/C/KM compact units. Melt water is not optional.
• Air / oven alley. Front-in / front-out cabinets (F-330BAK, KM-81BAK, KM-161BAK, AM-50BAK, C-80BAK) exist for tight holes. They still reject heat into a room that Kitchen Spot already called out as a bakery derate. A boxed-in louver is another derate. Use the 90/70 column if you have it.
• Water-cooled condensers dump heat into condenser water. Many cities restrict once-through cooling. Do not pick water-cooled to hide an oven-alley install without a mechanical reason.
• Filter. Ice-machine filter, not the espresso cartridge and not a flaker-forbidden 4HC-H on the F-330. See filters and descalers.
• Water pressure. Hoshizaki compact and F-330 pages list about 10–113 psig. Manitowoc NEO copy on the directory pages lists 20–80 psi. Too little pressure and harvest fails.
• Ice that goes into dough is an ingredient. Follow the clean/sanitize interval on the machine sheet. We are not writing a health-department letter.
• Do not use a household countertop nugget machine as if it were NSF commercial equipment unless the listing says it is.

What this page is not

• Not a code letter. NSF marks and manuals are on the sheets. We do not say an install “meets” a health department.
• Not a review. No scores, no invented “we installed N of these.”
• Not a price list.
• Not a cafe, restaurant, or office guide. Those venues keep their own pages. A bakery cafe still uses the cafe drink math for glasses.
• Not an industrial bakery catalog. Howe, Ice Systems, North Star, and Holiday Ice publish that class. This directory does not carry those SKUs.
• Not pizza-commissary or bagel-plant design. Howe names bagels, cookies, pie crust, and pizza crust as doughs that use flake. The factor is still recipe ice, not a second invented guest number.
• Not healthcare. Dispenser families sold into hospitals are out of scope here.
