Automatic Roaster vs Mars V5 AI Coffee Roaster

For nearly a decade, Mars Roaster has established itself as a veteran in the field of automatic coffee roasting machines, with the first models introduced back in 2016. With almost 10 years of research and development, Mars has not only provided roasteries with stable and durable industrial automatic roasting solutions but has also continuously innovated to meet the evolving demands of both domestic and global markets.

The latest milestone is the launch of the Mars V5 – a smart AI-powered coffee roaster. This marks not only a remarkable transformation but also a comprehensive upgrade: from flavor memory and replication to optimized operations that help coffee brands achieve consistent quality and large-scale competitiveness.

Yet many still wonder about the differences between Mars’s two most advanced product lines — Mars V4 and Mars V5. So, which is the right choice for your production needs and business goals?

Overview of Mars V4 Automatic Roaster

The Mars V4 industrial coffee roaster is designed to maximize automation in roasting processes. It was built to meet high-volume production demands while allowing detailed control over many steps in the roasting cycle.

• Mars V4 can store up to 28 different roasting profiles, accommodating diverse needs — from Robusta, Arabica, traditional phin brewing, espresso, to unique custom flavor profiles.
• Once a successful roast batch is set up, the machine automatically records and saves it as a “standard profile.” Later, operators can simply select the saved profile, and the machine will replicate the exact parameters for consistency.
• Users can program and adjust up to 20 separate roasting steps. After programming, the system runs nearly 100% automatically.

Strengths of Mars V4 Industrial Roasters

• Cost-effective investment: Mars V4 models are more budget-friendly than Mars V5, making them ideal for roasteries seeking modern industrial roasting machines while optimizing initial investment costs.
• Detailed process control: Best suited for businesses with skilled technicians, as V4 allows direct, detailed configuration of roasting parameters, enabling operators to craft signature brand flavors.

Limitations of Mars V4

• Influence of external variables: Roasting results are affected by ambient temperature, bean moisture, and bean density. Example: The same Robusta batch roasted for 16 minutes may require 3 different profiles (morning, afternoon, evening) to achieve consistency due to temperature shifts.
• Quality inconsistency: Continuous changes in external factors can result in varying flavor outcomes, making it difficult to maintain strict quality uniformity.
• Dependence on skilled operators: Without experienced roasters, the machine may not achieve the desired quality, increasing risk of errors.
• Labor-intensive management: Large-scale roasteries may require multiple skilled roasters to operate Mars V4, raising management challenges and labor costs.

Overview of Mars V5 AI-Powered Smart Roaster

The Mars V5 AI Roaster marks a revolutionary milestone for the coffee roasting industry in Vietnam, introducing AI integration as a “game-changing innovation.”

Unlike traditional roasters requiring manual multi-step programming, Mars V5 allows the operator to simply input:

• The roast profile
• Total roast time
• Percentage of time for each roasting stage (Drying – Maillard – Finishing)
  

With just one start command, the AI system automatically calculates, analyzes, and optimizes roasting parameters in real time. Both experts and beginners can achieve precise, consistent, and efficient results — saving significant time, effort, and manpower.

Key Advantages of Mars V5

1. Smart Features

• AI automatically analyzes coffee bean characteristics and environmental factors, adjusting parameters in real-time for consistent results.
• One-touch operation streamlines the entire process — AI monitors and controls roasting automatically from start to finish.
• Ensures uniform flavor quality, even across diverse coffee lines, vital for brand reliability and long-term growth.
  

Smart Features of Mars V5

2. Safety Features

• Equipped with multi-layer safety systems and certified CE + ISO 13849 sensors.
• If irregularities are detected during pre-check, the system issues immediate warnings and automatically shuts down depending on severity.
• During roasting, any fault triggers an emergency stop: the system switches to manual safety mode — flame off, airflow maintained, and drum rotation continues to protect beans from burning.
• Models ≥15kg capacity include water quench valves to extinguish fires quickly, protecting assets and human life.
• Mars V5 is therefore not just a smart roaster, but also a safety shield for both operators and facilities.
  

3. Advanced Management

• Roast data storage for up to 10 years for full traceability, production control, and detailed reporting.
• IoT connectivity enables remote monitoring and management.
• Profile access security: Only the owner can create/edit profiles, while sub-accounts may use pre-set ones. This safeguards proprietary roasting recipes and standardizes operations, reducing human dependency.
  

Mars V5 Smart Roaster

Limitation of Mars V5

• Higher cost compared to Mars V4, due to advanced AI integration and extensive safety + management features. It is best suited for medium to large roasteries with strict quality and consistency requirements.
  

Which Roaster Should You Choose – Mars V4 or Mars V5?

Your decision depends on your roastery’s scale and business objectives. Each model offers unique strengths to serve different needs.

Consistent coffee bean quality

Mars V4 – Cost-Effective for Small to Medium Roasteries

• Strength: More affordable, ideal for small and medium businesses.
• Requirement: Skilled staff must actively control variables (ambient temp, bean moisture/density) for stable results.
• Best fit: Businesses less focused on absolute flavor uniformity, and willing to accept slight variations.

Mars V5 – Smart Solution for Sustainable Growth

• Strength: AI simplifies operation, ensures consistent results, reduces human dependency, and enhances safety.
• Benefit: Standardizes large-scale production, ensures stable quality, and supports professional brand building.
• Best fit: Businesses aiming for full control, scalability, reduced risks, and brand credibility through uniform flavor.
  

If Mars V4 is the “cost-saving” solution, then Mars V5 is the “sustainable investment.”
Mars V5 not only reduces operational and management burdens but also elevates brand value, building strong consumer trust.
