Space is at a premium in coffee trailers, so a thoughtful layout is vital. Make sure to:
Keep prep areas separate from the coffee-making zone.
Use under-counter fridges beneath stainless steel counters for milk, butter, or sandwich ingredients.
Store dry goods—like bread or sugar—in labeled, sealed containers tucked away in mounted or overhead cabinets.
Tip: Trailers by ZZKNOWN offer tailored interiors with built-in fridges and layered workstations to streamline prep.
Always wash hands before handling food.
Wear gloves when dealing with ready-made items like pastries or sandwiches.
Stick to hairnets, aprons, and skip any jewelry.
Ensure a hand-washing station is on board with soap, paper towels, and clean water.
As dietary preferences grow, prep must accommodate them:
Keep designated tools for vegan, gluten-free, or nut-free prep.
Clean surfaces between different orders.
Clearly label anything that contains soy, dairy, nuts, or gluten.
Example: Use a separate knife and board when making a vegan sandwich to avoid cross-contact with meat or cheese.
Typical trailer fare includes:
Sandwiches and toasted bagels
Muffins, pastries, and cakes
Oatmeal, yogurt bowls, or salads
Use efficient gear:
A sandwich press, mini oven, or microwave is ideal.
Ensure proper ventilation for electrical appliances.
Clean equipment and hot surfaces daily.
Recommended Tools:
Compact sandwich grill
Mini convection oven
Fridge/freezer combo
Dual-basin stainless sink
"First In, First Out" cuts waste and ensures freshness:
Keep visible use-by dates on all products.
Rotate dairy, meats, and produce each day.
Use a basic inventory log or integrated POS tracker.
Store perishables like cheese or yogurt in sealed containers in the fridge.
Include:
Prep date
Contents
Expiry date
Dry items (beans, flour, tea) should go in airtight, pest-proof bins.
Disinfect all prep tools and stations frequently:
| Item | When to Clean |
|---|---|
| Knives & cutting boards | After each use |
| Counters | Before and after service |
| Sandwich press | Daily |
| Sink basin | Every few hours |
Use food-safe cleaning agents and color-coded cloths to avoid cross-contamination.
Customers expect the same taste each time:
Use set recipes (e.g., turkey club = 3 slices turkey, 2 bacon, 1 cheese).
Place visual guides above stations.
Train staff to use pre-portioned ingredients.
Bonus: This helps with stock control too.
Slice meats, cheese, and veggies in advance.
Pre-fill condiment bottles or garnish trays.
Prepping ahead means quicker service and happier customers.
| Section | Equipment & Storage |
|---|---|
| Cold prep | Under-counter fridge, knife set, board |
| Hot zone | Sandwich press, oven, spatula |
| Snacks & baked goods | Display case, tongs, wrapped items |
