Sterilizers and Pasteurizers

A full sterilizers and pasteurizers’ portfolio featuring different technologies depending on the specific product and application.

We are internationally renowned for our leadership in the field of sterilization and pasteurization for a huge variety of food and liquid food products. Our wide range of sterilizers features different technologies (tubular/concentric, tube/scraped surface, heat exchanger systems, etc…) depending on the specific application industry (liquid food/ semi-liquid and viscous food).
From our Olimpic range (a wide sterilizers’ portfolio dedicated to food and liquid food products) up to our innovative Stematic Long Run (specifically engineered for sterilizing Milk and Dairy products with UHT technology).

Olimpic TC

Sterilizing plant designed for processing products with high consistency and viscosity values

Olimpic TC

High performance and maximum reliability characterize the Olimpic TC sterilizing plant, designed for processing products with high consistency and viscosity values, destined for subsequent aseptic filling.

OVERVIEW

 

The product is subject to a thermal cycle by means of indirect heat exchangers, concentric pipe type, made of four pipes having decreasing diameters and placed one inside the other. Product flows inside the central annular space, while heating or cooling fluids circulate both inside the internal and external jackets, in counter-current to the product. CFT Group’s patented special flange allows hygienic design and reduced thermal expansions.

This aseptic process allows to preserve product at room temperature over long periods of time, while the whole plant is fully automated.

The plant is normally included in a complete aseptic production line, providing the following processing phases:

  • Product sterilization by means of the Olimpic TC plant
  • Intermediate aseptic product storage in horizontal or vertical tanks (optional)
  • Sterile bag filling by means of an aseptic filler
Olimpic TC

PRODUCTS: tomato juice, tomato pulp, tomato paste, pizza sauce, ketchup, jams and marmalades, fruit purees and concentrates, soups, baby food

BENEFITS:

 

  • Patented heat exchanger technology, resulting in hygienic design, no stress due to thermal expansion, and fully drainable
  • Easy and fast maintenance, with no need for inner bundle full extraction
  • Working capacity from 1000 up to 18000 Kg/h
  • Maximum thermal exchange efficiency and process uniformity
  • Product viscosity up to 10000 cP
  • Reduced washing times by means of backflush included in the cycle

Olimpic FT

Aseptic sterilizer for low and medium viscosity food products
Play video
Olimpic FT

The OLIMPIC FT sterilizer and pasteurizer series is designed for sterilizing low and medium viscosity food products such as milk, juices and fruit drinks, concentrated fruit juices and vegetable juices, natural fruit purees, vegetable milks and smoothies.

OVERVIEW

 

The shell and tube heat exchanger are the core point of this equipment. The tubular heat exchanger guides the product through several straight inner tubes surrounded by a service medium in a shell.

Straight pipes can be corrugated to increase the heat transfer coefficient. Energy savings can be obtained through a system with an intermediate loop product/water/product or by product-to-product tubular exchangers, which guarantees up to 80% energy recovery. The inner bundle of the product-to-product exchangers can be removed for inspecting the product flow path.

Olympic FT can be coupled with all the CFT aseptic fillers. or with CFT piston fillers in pasteurizer version.

Olimpic P plates

Plate heat exchanger for liquid food and other beverages.
Play video
Olimpic P plates

The OLIMPIC P series of sterilizers and pasteurizers is manufactured with plate heat exchanger for preheating, pasteurizing and cooling liquid products such as dairy products, beers and other beverages.

OVERVIEW

 

Olimpic P consists of a unit of corrugated metal plates with openings to allow the two fluids to pass separately through and between the heat exchange plates. The plates are compressed between the fixed frame plate and the movable pressure end plate by mechanical tie rods. The plates have a gasket that seals the channels between the plates and directs the fluids to the alternating channels. The size and number of plates are determined by the flow rate, the physical characteristics of the fluids and the thermal requirements.

Olimpic P plates

PRODUCTS: milk, milk-based and non-milk drinks, concentrated fruit purees, beer, liquid food

BENEFITS:

 

  • Maximum thermal exchange efficiency and process uniformity
