What is a vacuum kettle?
A vacuum kettle is an industrial system designed for cooking and concentrating food products under vacuum conditions. Using vacuum technology, the vacuum kettle preserves aroma, color, texture, and nutritional properties while improving product quality and process efficiency.
How does a vacuum kettle work?
A vacuum kettle operates by reducing the boiling temperature of the product through vacuum pressure. This allows gentle cooking and efficient concentration at lower temperatures, protecting sensitive ingredients.
All process parameters inside the vacuum kettle, including temperature, cooking time, and mixing speed, are automatically managed through a PLC control system.
Which products can be processed in a vacuum kettle?
An industrial vacuum kettle is ideal for processing:
- Jams and preserves
- Toppings and creams
- Dressings, such as balsamic vinegar reductions
- Sauces and industrial food preparations
The vacuum kettle ensures consistent concentration and high-quality results across different applications.
What are the main advantages of a vacuum kettle?
The main benefits of using a vacuum kettle include:
- Gentle product processing through vacuum technology
- Production capacities from 50 to 1000 kg
- High-efficiency condenser system
- Real-time flavor correction during processing
- Faster cooking cycles and repeatable production results
A vacuum kettle also helps maintain product color, taste, and texture compared to traditional cooking systems.
How are ingredients loaded into the vacuum kettle?
Ingredients can be loaded into the vacuum kettle using flow meters or load cells, ensuring precise, controlled, and repeatable dosing during every production cycle.
How are cooking parameters controlled in a vacuum kettle?
The vacuum kettle is equipped with a PLC automation system that controls all processing parameters, including:
- Temperature
- Vacuum level
- Cooking time
- Mixing speed
This guarantees maximum process accuracy with minimal manual intervention.
How is the final product transferred from the vacuum kettle?
After processing, the finished product is transferred directly from the vacuum kettle to storage tanks or downstream production lines while maintaining product uniformity and quality.
What are the key technical features of a vacuum kettle?
INOX-FER vacuum kettles include advanced technical features such as:
- Vertical cylindrical structure with double jacket
- Scraper blades to prevent burning and buildup
