How to plan a catering trailer interior step by step

The interior design of a catering trailer determines what everyday work will look like after starting the business. In a small space you need to combine product preparation, heating and cooling devices, water, warehouse, packaging, sales and space for employees. Even a well-equipped trailer may be uncomfortable if individual elements are arranged without taking into account the sequence of activities performed.

Therefore, it is not worth starting interior design with choosing furniture. First, you need to know the menu, product preparation technology, list of devices, number of people working at the same time and expected service speed. Only then can you create a layout of workstations that will support work instead of hindering it.

Why is the interior layout of a catering trailer so important?

A catering trailer has a limited area, so design errors are much more noticeable than in a large stationary establishment. A poorly positioned refrigerator may block the passage, an open cabinet door may make it impossible to use the sink, and a device placed a few dozen centimeters too far may mean hundreds of additional movements during one working day.

In practice, it is not about "fitting all the devices" inside. A good design should allow you to conveniently perform subsequent activities.

The employee must collect the product, prepare it, process it, add ingredients, pack it and deliver it. If at every stage he has to go to the other end of the trailer, squeeze past a co-worker or open a door-blocking device, even a large interior may not function properly.

The aim of the project is not to make the most of every centimeter. The goal is to create a logical work system.

Start with the menu, not the furniture

One of the most common mistakes is starting the project by choosing cabinets, countertops and the appearance of the interior.

Meanwhile, the first document should be menu.

Each menu item represents a specific process and equipment. A burger requires a different station than a pizza, a kebab a different station than ice cream, and rotisserie chickens yet another.

For example, for burgers you may need:

• grill plate,
• fryers,
• meat cooling,
• cooling vegetables,
• place for rolls,
• sauces,
• folding station,
• space for packaging,
• issuing area.

When making pizza, the following will be important:

*packing.

• bake,
• space for cake,
• refrigerated table for ingredients,
• pizza forming countertop,
• post-baking station,
• cutting,

When it comes to kebabs, there are, among other things, vertical grills and ventilation that is very important.

Therefore, one additional dish on the menu can affect the entire project.

If you add fries to burgers, a fryer appears. If you add coffee - an espresso machine, milk cooling, cups and a barista work area. If you're adding a dessert, you'll need additional ingredients, utensils, or appliances.

The earlier the menu is established, the more predictable the design will be.

Describe the process of preparing one order

Once you know the menu, you need to analyze a single order.

Don't start drawing the interior just yet.

Record step by step what happens from the moment the order is accepted to its release.

An example process in a burger restaurant may look like this:

1. 1acceptance of the order,
2. 2meat collection,
3. 3grilling,
4. 4preparing the roll,
5. 5getting vegetables,
6. 6adding sauces,
7. 7assembling the burger,
8. 8preparation of fries,
9. 9packing, 10th edition.

Then assign a device or workstation to each step.

In this way, the first functional map of the interior is created.

If two subsequent stages require devices located next to each other, it is worth taking this into account in the design. If an employee must move hot product throughout the interior, it may be worth examining whether the layout can be simplified.

Divide the interior into work zones

A well-designed trailer can be divided into several basic zones.

Not every trailer needs all of them to the same extent, but it is worth analyzing them.

This does not mean that you need to build eight separate rooms in a small trailer. Zones can connect.

However, it is important that their functions do not conflict.

How to plan the order reception area?

The place where orders are accepted is usually located at the sales window.

May include:

*small accessories.

• cash register,
• terminal,
• POS system screen,
• space for numbers,
• printing receipts,
• menu,

When traffic is low, the same person can take and issue orders.

If there is a large number of customers, it is worth considering separating these functions.

One place takes orders, the other one delivers.

This solution can improve customer flow, but has a space cost. The second window occupies a part of the wall on which it will not be possible to install a full structure.

Therefore, the decision on the number of windows must be made at the design stage of the structure, and not after the interior is completed.

Product preparation area

This is one of the most intensively used places.

The work surface should be adapted to the number of activities performed simultaneously.

With a short menu, one countertop can perform several functions. When selling more, combining everything on one surface quickly becomes a problem.

It is worth determining:

• how many people work on the preparation,
• how many GN containers must be available,
• where tools are stored,
• is cooling needed directly under the countertop,
• where finished semi-finished products are stored,
• where dirty tools go.

A good solution is to place the most frequently used products within easy reach.

Less frequently used supplies may be further away.

Where to place heating devices?

Grills, fryers, grills, rotisseries and ovens are devices that influence the design much more than a simple cabinet.

You need to take into account:

• dimensions,
• power,
• power supply,
• opening method,
• temperature,
• ventilation requirements,
• spacing,
• possibility of cleaning,
• serviceability.

Most often, it is worth grouping heating devices in one zone because it facilitates the ventilation design.

However, this is not always possible.

It is crucial that they do not cause collisions with cooling and the main passage.

Cooling and storing ingredients

Cooling should be planned at two levels:

products needed during current work and stock.

For example, a burger restaurant may have a refrigerated table with meat, cheese and vegetables available directly at the counter and an additional refrigerator for storage.

If everything is in one large refrigerator at the end of the trailer, an employee may be making dozens of unnecessary passes per hour.

When designing cooling, check:

• door opening direction,
• pulling out drawers,
• ventilation of the device,
• access to the generator,
• space for cleaning,
• distance from heating devices.

Washing zone and water installation

The sink and washbasin take up more space than visible on the top view.

Underneath you may find:

• clean water tank,
• used water tank,
• pump,
• heater,
• wires,
• valves,
• drain.

This means that the space under the sink often cannot be used as regular storage.

The design must also provide access to the pump, cables and components requiring service.

Warehouse – the most underrated part of the trailer

Everything looks good in the visualization until we add supplies.

You need to store somewhere:

• products,
• bread,
• spices,
• sauces,
• packaging,
• mugs,
• napkins,
• towels,
• cleaning products,
• gloves,
• bags,
• cutlery.

If the trailer is operated without additional storage next to it, the space requirement increases.

Before approving the interior, it is worth answering the question:

how many working hours should the trailer handle without replenishing supplies?

This completely changes the design.

How many countertops do you really need?

Too little countertop is a common problem.

Too much can also be a mistake because the countertop takes up space that could be used by an appliance or a walkway.

Every surface should have a function.

For example:

• product preparation,
• putting aside after processing,
• packing,
• publishing.

It is not worth designing one very long surface without considering who will use it and how.

Sales window and dispensing station

The window affects the interior and the façade at the same time.

There is often a sales counter underneath it.

Nearby you need to plan:

• ready orders,
• terminal,
• packaging,
• drinks,
• accessories,
• place of the customer receiving the product.

If the window is too close to the cooking zone, the customer service employee may block the cook.

If it is too far away, the finished dish has to travel an unnecessarily long distance.

How to plan the work of one person?

One person needs a system that is as compact as possible.

The most important devices should be located close to each other.

However, this does not mean that the interior has to be cramped.

One person must simultaneously:

• prepare,
• operate devices,
• accept orders,
• pack,
• spend
• clean up.

Therefore, it is worth minimizing distances.

How to plan the work of two people?

If you have two employees, it is worth dividing the tasks.

For example:

Person 1: grill / stove / fryer.

Person 2: folding / packing / customer.

The arrangement should allow both people to work without constantly crossing each other's path.

If they both have to use one refrigerator between stations, a bottleneck quickly develops.

What does three or four employees change?

In a larger team, there is a problem of communication.

It's not enough to make the trailer bigger.

Roles need to be separated.

For example:

1. 1heating devices,
2. 2preparation,
3. 3packing,
4. 4cash and spending.

If each employee can stay primarily in their own zone, work is much smoother.

Electrical installation and interior layout

Sockets should be located where devices are.

It sounds obvious, but it requires knowledge of the equipment before installation.

It's not enough to say:

"Let's provide a lot of sockets."

Need to know:

*where will they stand,

• what will be connected,
• what is the power,
• which devices work simultaneously,
• whether they are mobile or permanently installed.

Example: the stove, grill, fryers, cooler and heater can operate simultaneously. The number of sockets alone does not indicate whether the installation has been planned correctly.

Ventilation and arrangement of devices

Ventilation is not an add-on that can be easily fitted at the end.

The hood takes up space above the appliances.

The wires need to be routed somewhere.

Filters must be available.

The air removed from the trailer must also be adequately replenished.

Therefore, the heating zone should be analyzed together with ventilation when creating the plan.

Service access – a space that is often forgotten

The device can fit perfectly between two cabinets.

The problem comes when you need to get to its back.

The design should provide for:

• access to generators,
• valves,
• wires,
• drains,
• pumps,
• filters,
• switchboard,
• ventilation elements.

Some components will be serviced rarely, but when a failure does occur, lack of access may mean dismantling the structure.

Doors, drawers and device collisions

In a static view, everything may look fine.

Therefore, you must draw the elements in an open position.

Check:

• refrigerator doors,
• drawers,
• furnace door,
• cabinets,
• entrance door,
• dishwasher,
• fryer baskets.

Ergonomics and number of steps while working

One simple way to evaluate a project is to count the distance of one order.

Let's say you place 150 orders a day.

If an employee makes four unnecessary passes through the trailer each time, the scale of the problem becomes much greater after a whole day.

Therefore, a well-designed interior can impact productivity without increasing the number of employees or equipment.

Sample layouts for various types of catering

Burger place

Logical sequence:

meat cooling → grill → ingredients → assembly → packaging → serving.

Fryers should be in the hot zone but not blocking the folding station.

Kebab

Logical sequence:

toaster → meat cutting → additions → sauces → packaging → serving.

Ventilation and air circulation are very important.

Pizza

Logical sequence:

dough → forming → ingredients → bake → cutting → packaging → serving.

The key is to position the oven in relation to the preparation counter.

Rotisserie chickens

Logical sequence:

cooling → preparation → rotisserie → portioning → display/packing → dispensing.

The hot and cooling zones require a particularly well-thought-out separation.

Ice cream

Other needs dominate here:

cooling → exposure → portioning → additions → dispensing.

Convenient product refilling and comfort of operation of refrigeration devices are of great importance.

The most common mistakes when designing an interior

1. 1Buying devices without a common design. Individual pieces of equipment may match their dimensions, but together they may not create a functional system.
2. 2No space to open devices. The refrigerator fits on the floor plan, but the open door blocks the passage.
3. 3Too little work surface. All activities are carried out on one countertop.
4. 4No stock. Packaging and supplies begin to occupy the aisles.
5. 5Placement of heating devices without ventilation analysis.
6. 6Too few electrical points or their incorrect arrangement.
7. 7No service access.
8. 8Copying the interior of another company. A similar menu does not mean an identical way of working.
9. 9Designing for a quiet day instead of rush hour.
10. 10No room for menu development.
11. 11Too many "just in case" devices.
12. 12Approval of windows and doors before interior design.

How to check the design before starting production?

Before committing your design, run a simple simulation.

Imagine your peak sales hour.

All employees are inside.

Then go through some orders.

Check:

• who opens the fridge,
• who is standing at the grill,
• who uses the sink,
• who packs,
• who serves the customer.

Do their paths cross?

Can any device be opened?

Is access to the most frequently used products convenient?

Does the employee have to take several steps for each ingredient?

A simple test can reveal problems that are not visible in the visualization.

13. 13only then approve the windows, doors and development.

Frequently asked questions

Where to start designing the interior of a catering trailer?

From the menu and the way the products are prepared. Only then should you select the devices and arrange the stations.

Can the manufacturer design the interior based on my device list?

Yes. The more precise the device data - dimensions, power, opening method and technical requirements - the more accurate the design can be.

Is it worth buying the devices first?

It is best to choose specific models in advance or at least know their parameters. The physical purchase of all devices does not always have to take place before production, but the project should know their actual dimensions.

How many countertops are needed in a trailer?

There is no single number. The working area should result from the number of activities and people working at the same time.

Should heating devices be next to each other?

This often makes it easier to design ventilation, but the layout must also correspond to the sequence of work.

Can the refrigerator be placed next to the grill?

Depends on devices and design. It is worth limiting the impact of strong heat sources on refrigeration devices and taking into account the requirements of equipment manufacturers.

How to plan an interior for two employees?

It is best to separate roles and assign each person a main zone. The layout should limit the need to constantly pass each other.

Does a bigger trailer solve the problem of poor layout?

No. A larger interior may still function poorly if devices and stations are placed out of order.

Can the sales window be moved later?

Technically, it may be possible, but it usually means interference with the structure and development. It is much better to determine its location before production.

How much space should I leave for my future device?

It is not worth leaving a large empty space without a specific plan. However, if the menu development is realistic, it is worth preparing the place or installation for a specific type of device in advance.

Does trailer layout affect service speed?

Yes. The fewer unnecessary movements employees make during one order, the easier it is to maintain smooth operation during peak hours.

Should the project include device service?

Yes. Access to pumps, lines, filters, units and other service elements should be taken into account before construction.

Don't know how to arrange the interior of your trailer?

Prepare a menu, a list of devices and information about the number of people who are to work at the same time. On this basis, you can plan zones, the layout of stations and the size of the trailer corresponding to the actual way of working.
