Four jobs, four sizing bases
| Job | Typical band | Usual equipment | Size it by |
|---|---|---|---|
| Ingredients: butter, cream, milk, eggs, cheese, fillings | +2 to +5 °C | Reach-in or undercounter near the bench | Stock days × daily use, in tubs, blocks and cartons |
| Finished cream cakes and desserts awaiting sale or pickup | +2 to +5 °C | Reach-in with adjustable shelves | Cake boxes per shelf × shelves |
| Frozen dough, laminated sheets, fruit, ice cream | −18 °C or colder | Chest or upright deep freezer | Cartons and trays, stock days |
| Display of pastries, cakes and desserts | About +4 to +8 °C at product, depending on item | Refrigerated pastry showcase | Pieces per tray × trays per deck × decks |
Ingredient storage close to the bench
Laminated doughs need butter firm and cold, so the ingredient fridge belongs within a step or two of the sheeting bench. An undercounter with a worktop gives both cold storage and work surface in hot rooms. Work out stock as daily use × days between deliveries: for example, 8 kg of butter a day with deliveries every three days means about 24 kg on hand, plus cream and dairy in the same way.
Opening frequency matters as much as volume. An ingredient fridge opened every few minutes needs good recovery, and a busy bakery room near ovens can run well above 40 °C. Ask for the ambient the unit is rated to work at.
Finished cakes: count boxes, not litres
Measure your most common cake box. Worked example with assumed figures: a 1 kg cake box of 250 × 250 × 120 mm on a shelf of 650 × 530 mm fits 2 × 2 = 4 boxes, since 650 ÷ 250 = 2.6 and 530 ÷ 250 = 2.1. With a shelf pitch of about 150 mm, a cabinet with 7 usable levels per door holds 28 boxes per door. If your peak is 45 cakes waiting for evening pickup, plan two doors, or one door plus space in the display.
Taller celebration cakes need wider shelf pitch, which reduces the number of levels. Adjustable shelves are worth more than extra litres here.
Sizing the pastry display
Display is sized by pieces on show at your busiest time. Worked example with assumed figures: pastries with a 70 × 70 mm footprint need roughly 90 mm spacing so tongs and labels fit. A 600 × 400 mm tray holds 6 × 4 = 24 pieces (600 ÷ 90 = 6.7, 400 ÷ 90 = 4.4). A display deck 1.2 m long × 0.5 m usable depth holds 13 × 5 = 65 pieces at the same spacing; three decks give about 195 pieces.
If you sell 400 pastries a day, a case showing 195 pieces needs refilling at least once during the day, which is normal. If refilling is impractical, add length rather than cramming pieces closer.
Freezer space for dough and fillings
Bakeries that freeze dough pieces or laminated sheets on trays need flat shelf space, which suits an upright freezer. Bulk frozen fruit, fillings and bought-in frozen products in cartons pack more tightly into a chest freezer. Size from cartons and trays per delivery cycle, then add space for a batch you have just made and need to freeze.
Indian conditions that change the answer
- Monsoon humidity causes condensation on cold glass and sweating on chilled cakes brought into a humid shop. Display cases are tested under defined room climates (the display cabinet standard is ISO 23953); ask which test climate the case is rated for and compare it with your shop.
- Non-AC shopfronts with afternoon sun on the glass add heat load to the display. Shade the case or move it back from the window.
- Cream products should be held at chilled temperatures; common food-safety guidance is 5 °C or below. Keep cakes awaiting pickup in back-of-house cabinets, not the display, if the display runs warmer for presentation.
- Mithai, cream and chocolate items have different needs. If one display serves all, the warmest-tolerant item cannot set the temperature for the rest.
Frequently asked questions
- Can one refrigerator serve both ingredients and finished cakes?
- In a very small bakery it can, but it is a compromise: ingredient access opens the door constantly, and cakes near the door see the warmest air. Once volumes grow, separating ingredient and finished-goods storage is usually the first upgrade worth making.
- How long should the pastry display be?
- Long enough to show your peak range at sensible spacing, as in the tray calculation above. Work out pieces per deck from your real product sizes, then choose the length that holds the range you want visible at the busiest hour.
