Consulting on the design of industrial kitchens with integrated Josper oven

Designing an industrial kitchen for a high-end restaurant always requires precise calculations right from the core equipment. In particular, Josper oven – a charcoal grill line favored by many Michelin chefs – not only creates the unique flavor of grilled dishes, but also determines how the entire hot kitchen is operated. Integrating Josper into kitchen design is therefore not simply about adding an additional device, but creating a sustainable, safe and efficient operating ecosystem.

Josper is called the “gold standard of charcoal grills” thanks to its special combination of open grill and closed grill, creating a stable temperature of 250–350°C and preserving the charcoal flavor. However, the high heat level, coal-powered operating mechanism and specific ventilation requirements make designing the Josper integrated stove a job that requires deep technical knowledge and cannot be done according to common experience.

That’s why investors and chefs are always looking for professional industrial kitchen design units, understanding the structure – capacity – safety requirements of Josper, to ensure the kitchen operates smoothly from the first day. With experience in implementing many fine dining, steakhouse and 5-star hotel models, Saigon Horeca offers Josper integrated kitchen design solutions according to international standards: optimizing airflow, smoke treatment, reasonable equipment layout and ensuring absolute safety.

The following section will help you understand the most important factors when designing an industrial kitchen with an integrated Josper oven – from technical standards, space layout to operating procedures – to make the correct decision for your restaurant.

Why do many restaurants take risks when integrating Josper ovens into their kitchens?

The Josper oven brings a characteristic charcoal flavor, but its high heat structure and charcoal operating mechanism makes the arrangement of this device in an industrial kitchen much more complicated than conventional thermal devices. In actual implementation, many restaurants, despite investing in expensive equipment, still encounter problems, affecting operations and customer experience. Below are the most common mistakes.

1. Not properly calculating the ventilation system – specialized smoke extraction

Josper operates at high temperatures of 250–350°C and uses charcoal, so the amount of smoke produced is greater than gas or electric devices.

If not designed correctly:

• Smoke flows back into the hot kitchen
• The smell of charcoal affects the customer service space
• Unstable wind pressure → reduces coal burning efficiency
• Risk of heat accumulation under the hood

This is why Josper clearly recommends: errors in ventilation arrangements are the leading cause of heat and smoke incidents.

2. Wrong location causes interruption of operating flow

Many kitchens place Josper based on their feelings, leading to:

• The baking line is separated from the preparation line
• Narrow operating space
• The pick-up and return distance is not optimal
• The chef has to move too much, causing slow service speed

For a device with high capacity like Josper, placing it in the wrong position is not only inconvenient but also affects peak service productivity.

3. Lack of standard heat-resistant and fire prevention material solutions

Manufacturer Josper warns that not keeping a safe distance from flammable materials can lead to fire and explosion. However, in many projects:

• The surrounding walls have not been covered with heat-resistant materials
• Stainless steel table is not thick enough
• There is no insulation on the back and sides
• The floor in the Josper area does not meet anti-slip and heat-resistant standards

These factors pose a great risk, especially in kitchens that operate continuously for many hours a day.

4. Do not calculate in advance the heat load and impact on the working environment

Heat from the brazier directly affects:

• The kitchen temperature increased
• Personnel get tired quickly, reduce productivity
• Grease evaporates more strongly, making it difficult to control and clean
• Cooling costs increased significantly

If there is no suitable solution for getting fresh air and releasing heat, the working environment will become too hot – a big no-no in high-end restaurant kitchens.

5. Not balancing oven capacity with output and menu

Common mistakes:

• Small restaurant but choose large model
• Steakhouse seats 80 guests but uses the type for 30–40 guests
• The menu has many charcoal-grilled dishes but the processing line cannot support them promptly

Josper has many lines with different capacity levels, sizes and service output; If not properly advised, the restaurant can easily fall into the following situation:

• Oven overloaded → slow service
• Excess furnace capacity → waste and waste of coal

The Josper oven is a great equipment for restaurants pursuing premium charcoal flavor. But to exploit properly, safely and effectively, the kitchen design needs to be done by a unit with deep expertise – understanding both technique and practical operation.

This is Saigon Horeca’s advantage: we not only install equipment, but provide comprehensive advice on airflow – location – safety – workflow – performance based on experience deploying many practical Josper models.

How does Saigon Horeca approach the design of an industrial kitchen with an integrated Josper oven?

Integrating Josper ovens into industrial kitchens is not only a technical problem, but also an operational problem and optimizing productivity. With experience implementing many high-end restaurant projects, Saigon Horeca has built a unique approach, based on 3 core elements: understand equipment – understand operations – understand business model.

Below is the process we apply in every project using Josper furnaces.

1. Analyze menu, concept and service output

Josper is not a device that “can be placed anywhere”; It plays a central role in models such as steakhouse, tapas, charcoal seafood or fusion restaurant.

Therefore, Saigon Horeca begins with analysis:

• Type of charcoal grilled dish (steak, seafood, vegetables…)
• Frequency of furnace use in service
• Number of visitors per hour
• Priority of grilled dishes in restaurant concept

From this data, we determine:

• Suitable Josper Model (HJA 25M, HJA PLUS M, HJX PRO…)
• Service capacity (for example, HJA PLUS L175 is suitable for ~175 guests/hour)
• Number of rack levels and accessories needed to optimize capacity

Thanks to this analysis step, the furnace always operates in a stable state – no overload, no waste.

2. Calculate the ventilation system – smoke extraction – fresh air supply

This is the most complicated part and also the strongest part of Saigon Horeca.

Josper operates at a temperature of 250–350°C, creating a large amount of smoke and heat pressure. So we calculate each factor:

Suction flow rate (CFM) according to each Josper model

Each model has different wind requirements, ensuring smoke escapes quickly and does not spill back into the kitchen.

High-quality heat-resistant suction hood system

Use a specialized hood for charcoal equipment, capable of:

• high heat resistance
• anti-oil accumulation
• steady suction flow

Standard smoke filtration plan

Depending on restaurant location:

• Electrostatic filter
• Activated carbon
• Cyclone or industrial grease trap

Design heat-resistant pipes & optimize pressure

Fume pipes need to be calculated according to length, angle and material.

Additional fresh air supply

Helps stabilize coal burning, reduce negative pressure and resolve heat accumulation.

Thanks to a carefully calculated system, the kitchen operates safely – no smoke – no heat pressure, even though the oven is running at full capacity.

3. Layout design – optimize the workflow of the baking line

Saigon Horeca applies the philosophy “Josper furnaces must be located in the operating flow”, instead of just placed according to free space.

We determine:

• Food preparation station (prep station)
• Distance from refrigerator to oven
• Distance from oven to counter
• Working space for 1–2 chefs
• Safe exit when handling hot coal

General principles for Josper layout:

• One way – three zones: prep → bake → finish
• Do not cut off kitchen traffic
• Ensure the operator does not have to move much
• Minimum distance 800–1200mm around furnace for working area

Thanks to that, the grill line operates quickly, accurately and effectively even during peak hours.

4. Select materials, accessories and safe solutions

Due to high temperatures, Saigon Horeca only uses standard materials:

• 304 stainless steel 1.2mm–1.5mm thick for tables, cabinets and shelves
• Heat/fire resistant panels on sides and rear
• Heat-resistant non-slip floor in front of the oven
• Josper’s specialized gloves and tools (poker, tongs, shovel…)
• Safe distance from walls or flammable materials as recommended by the manufacturer

In addition, we optimize:

• Coal storage area
• Place to clean the ash tray
• Ash container with fireproof lid

All to ensure the kitchen meets international fire safety standards.

5. Optimize personnel and actual operations

One of the biggest differences of Saigon Horeca is that we calculate the design based on the final operator.

• How many furnace personnel are needed for each model?
• What is a reasonable distance to travel?
• How many plates/hour does the target service speed need to meet?
• Increase performance by arranging 1 or 2 rack floors?
• How to position spices, utensils and cutting boards to ensure speed?

Every element is optimized to ensure that only one operator still controls the grill line during off-peak hours, but when capacity is increased, it still runs smoothly.

Saigon Horeca approaches the integration of Josper ovens not only with technology, but also with operational thinking and a deep understanding of each restaurant’s business model.

The result is a kitchen:

• beautiful – compact – safe
• no smoke – no heat
• efficient operation
• maximize the power of Josper furnace
• and create a consistent, signature charcoal grilling experience every day

4. Sample kitchen layouts with integrated Josper (according to each restaurant model)

The arrangement of Josper ovens in industrial kitchens does not have a fixed formula. Layout must be designed based on menu – area – concept – operating process. However, based on practical experience, Saigon Horeca built three typical layout groups, representing the majority of Josper usage models in Vietnam.

1. Layout for Steakhouse 40–60 guests – Josper oven centrally located with hot line

This is the most popular model that Saigon Horeca deploys. Steakhouses often have menus revolving around red meat, seafood and grilled vegetables, so Josper is considered the heart of the entire kitchen.

Layout features:

• Josper is located in the center of the hot line, making it easy to distribute dishes to the pass counter.
• Prep station is located right next to the left so the chef can quickly season meat.
• The meat cooler is located behind the oven, helping to optimize the circulation of ingredients.
• Spice shelf – utensils are placed on the right hand side of the oven owner to reduce operations.
• Working distance is at least 1.0–1.2m to ensure safety when opening the oven door.

Advantages:

• Fast service speed, suitable for peak hours.
• Ensure one-way workflow: take meat → grill → rest meat → dish.
• Create a “show” position if it is an open or semi-open kitchen.

2. Layout for high-end Seafood Restaurant – Oven placed separately to prevent moisture

Seafood has high moisture content and lots of wastewater; If the baking line is placed too close to the processing line, it will cause moisture and slippage, reducing the life of the equipment. Therefore, Saigon Horeca separates the Josper area to protect equipment and optimize hygiene.

Layout features:

• Josper is placed independently in the thermal area, away from the seafood processing area.
• Separate sink for knives and tongs to avoid cross-contamination between meat and seafood.
• Seafood cooler placed behind or perpendicular to the grill line.
• The floor of the oven area uses heat-resistant anti-slip material, avoiding slipping when exposed to seafood oil.
• The smoke extraction system is designed to be larger to handle the amount of oil – grease – thick smoke.

Advantages:

• Minimize the risk of cross-contamination.
• Keeps your device cleaner and longer lasting.
• Increase the quality of grilled seafood – limit steaming.

3. Layout for 5-star Hotel – Optimize aesthetics & carefully hide smoke extraction system

In many 4–5 star hotels, the Josper kitchen is often located at live kitchen or open-kitchen, where customers directly observe the baking process.

Layout features:

• The Josper oven is located in the line show cooking or the center of the open kitchen.
• The smoke extraction system is hidden in the ceiling or has a recessed design, ensuring aesthetics.
• Arrangement stone – stainless steel working table, combined with lighting to enhance visual perception.
• The standing grilling area has been expanded to optimize performance in front of guests.
• Integrated auxiliary equipment: induction cooker, salamander, warming station.

Advantages:

• Brings a professional, high-end image.
• Optimize the guest experience when seeing the charcoal grilling process.
• Easy to control odors in luxurious spaces.

4. Layout for Kitchenette (mini bistro / pub / tapas)

Some small models with a menu focusing on 5–6 grilled dishes also use Josper mini ovens (eg HJX PRO S).

Layout features:

• Wall-mounted oven or built-in
• Integrated prep station 0.6–0.8m next door.
• 1-door refrigerator placed under the table to optimize space.
• Line is short but ensures 1 operator is still effective.

Advantages:

• Optimize costs and kitchen area.
• Still delivers the signature charcoal grilled quality.
