FREEZOLINE Individual Quick freezer (IQF):

General Information:

An external View of straight line IQF

Spiral freezer

In Today's world, food preservation is more important than ever before, Historically there were many Methods of food preservation, like drying, smoking, pickling, salting etc.. These rather primitive methods are still widely used today, not only in backward societies, where no other means are available, but also in modern societies where they serve to supplement the more modern methods of food preservation like refrigeration.

In the Individual Quick Freezing (IQF) process, unlike other freezing processes, the products are frozen as individual pieces. This offers greater convenience to the consumers and hence adds more value to the product. The IQF process is far superior to the conventional processes. In Quick freezing, small ice crystals forms within the product thus its own fresh quality is maintained even after extended shelf life. Most foods can be preserved for a long time if they are frozen quickly and kept at a low temperature until ready for use. Slow, natural freezing destroys food because the low temperatures draw all the water from the tiny cells of the food, affecting color and flavour.

Quick freezing method prevents breakage of the cell walls as the freezing process is so quick. Thus, in quick-frozen food most of the flavour, colour and firmness are retained.

Application of Individual Quick freezing (IQF):
  • Fruit & vegetables processing
  • Meat & fish Processing
  • Ready to eat products
  • Other Cooked Food items

FREEZOLINE Technical Description:

Rinac's IQF freezer is completely pre-fabricated, factory tested prior to shipping. The conveyor made of continuous belt, MOC either SS / PE / POE. The conveyor supports are made of Aluminum lined, low friction, food grade, plastic wear strips[UHMPV] designed for minimum belt wear. The enclosure of the chamber is constructed with rigid polyurethane insulation, of 150mm thick Wall & ceiling, 200mm thick for floor along with entry/inspection doors, walk ways with in the chamber along with stairs, located at critical locations for easy inspection, cleaning, and maintenance. The freezer is built to food grade standards.

Cooling coil will be of SS/Al construction with varying fin configuration for enhanced performances. The frigid air is delivered by high-efficiency aero-foil construction fan impeller which is directly driven by high efficiency motors. Both Straight and spiral units are equipped with water defrosting arrangement for coil. The straight line IQFs will have an automatic, advance Air Defrost technology[ADF] system for a longer operation period, between defrost intervals. The floor shall be of SS Finish with built in Clean Flow drainage systems. In feed conveyor is covered with insulated boxing & outlet feed with product collection tray. The straight line IQF units will have an infeed shaker unit at the product entry point.

The structure design and material selection results in lower maintenance requirements, longer component life and reduced downtime.

Benefits of FREEZOLINE FST IQF

The IQF freezing uses a bed of supercooled air to suspend and separate solid food products, simultaneously freezing them. Our IQF Conveyor design optimized for directing air evenly towards the product and ensures better quality crust freezing by locking the product moisture before the final core freezing, as well as preserving product weight, appearance and quality. Product Agitator in the pre-cooling section provided to avoid lumping of product.

  • The appeal of IQF frozen fruits and vegetables are near to the much-sought-after appearance, flavour and nutrition as of fresh ones.
  • Individually quick frozen products lock in the essential nutrients and flavour, with optimum colour, taste and texture.
  • The IQF process makes it possible to offer ’fresh picked’ flavours all year round, in packaging convenient for today’s busy consumer.
  • Two-Stage fluidization System Gives Optimum Freezing Process: The crust freezing zone (belt 1) and the deep freezing zone (belt 2).
Features of FREEZOLINE FST – Straight Belt Series
  • Factory Finished SS Floor with built in Drain arrangement.
  • Automatic air defrost system. Air Defrost system ensure beyond 18 hours of continuous operation without water defrost.
  • The electrical Control Panel includes extreme user friendly PLC touch screen control panel, emergency stop system along with VFDs and UPS control power.
  • Individually adjustable double Belt system for different product processing.
  • High velocity airflow inside freezers ensures high quality of freezing. The air flow is controlled to perfectly suit each product which gives an even temperature throughout the freezer and uniform high product quality.
  • Operate as complete standalone or option to operate in combination with other systems.
Air Defrost System [ FROST BUSTER ]

Straight line IQF units are equipped with automatic Air Defrost system, especially for processing vegetable & fruit products which carry high water percentage. The continuous removal of frost considerably extends the effective operation time and efficiency of freezing thus extending the time intervals between the defrost hence increasing the total daily production capacity over 25-30 %. Air Defrost system runs automatic with help of PLC based control system. The continuous air jet will remove frost from coil and prevent frost built-up during working, which results better air flow through coil and enhanced heat transfer.
