Finding new ways of making freezing technology more economical is a key aim for JBT. The company’s Frigoscandia brand was the first in the world to introduce individual quick freezing (IQF) technology on a process line back in the 1960s. The aim was to find an efficient way of quick-freezing fruit and vegetables, while maintaining product quality and profitability.
In recent years, JBT’s IQF technology has advanced to the extent that optimal production capacities of between one and 17 tonnes per hour can be achieved on the company’s Frigoscandia FLoFreeze. It also has the ability to modify airflow for different product types and sizes.
FLoFreeze uses true fluidisation, which enables the product to behave like a liquid, suspending each particle individually in supercooled air, while simultaneously freezing them. Each particle maintains its shape and freshness without sticking together. This is a key benefit when freezing delicate foods such as fine herbs, cheese, shrimp, cooked rice and pasta.
Making efficiencies in energy and costs continues to be a priority. This is why JBT developed the air defrost system (ADF), a unique system which guarantees a full 22 hours of running time at full capacity before defrosting. Torbjörn Persson, JBT’s portfolio and applications director, describes some of the benefits:
‘The main cost-efficiencies with the FLoFreez3eIQF system come from the savings in the duty requirements on the refrigeration as you don’t need to have a redundant evaporator constantly being defrosted and adding heat, which is what happens with a sequentially defrosted freezer. With the ADF system, compressed air is continually blasted through the evaporators to remove snow.
Two hours are then sufficient to carry out a full defrost and clean down,’ Persson says. ‘By which time the FLoFreeze is ready to start freezing again. As most producers can stagger their production this means they can operate efficiently on a 24/7 basis.’
JBT’s latest innovation is the Frigoscandia GyroCompact 40 Spiral Freezer. The new freezer has evolved from one of JBT’s best selling products, the GyroCompact Classic 400 Spiral Freezer, which has sold over 1 100 units throughout the world.
Ideal for smaller manufacturers, the GyroCompact 40 has a footprint of only 6.5m long and 2.4m wide. It’s so compact it can be shipped as one single piece of equipment, although its capacity is up to 40 per cent higher than any competitor freezer of a similar size.
JBT’s portfolio also includes DSI portioning systems, Stein coating, cooking, frying and filtering equipment, the Double D range of high impingement linear ovens and searer grill-markers, and Formcook contact and combi cookers which are ideal for surface treating or fully cooking flat products.
