IQF STATIC PLATE FREEZER
IQF plate freezers (Individual Quick Freezing)
combine the advantages of the individual
processing, required for certain
products, and those of direct contact
freezing:
Saving
Given the simplicity of its design, the IQF
plate freezer requires minimum initial
investment and energy consumption.
Besides this, Tucal offers as an alternative
the compact configuration (freezer connected
to the corresponding refrigeration
equipment), so that the installation on site
is very easy and economical.
Continuous operating regime
IQF freezers have static plates (without
movement), like shelves. The distance
between plates is calculated for an easy
and continuous operation, so that it is possible
to coordinate production and freezing.
Quick freezing
Besides the fastness of direct contact
freezing itself, the IQF plate freezer adds
the possibility of working in continuous
regime with the plates at temperatures
between –35° C and –40°C. The freezing
process begins thus at the precise moment
that the product is laid over the plate.
Product quality
The product is kept in optimum conditions
thanks to a freezing method that combines
individual treatment (IQF) and direct contact,
which avoids the dehydration and
losses caused by the mediation of air.

DESCRIPTION OF THE IQF STATIC FREEZER
As it happens in traditional plate freezers (horizontal and vertical
type), the freezing in the IQF plate freezer is achieved by direct
contact of the product with the plates, inside which the refrigerant
is circulating at a low temperature. In this case, the IQF static
freezer has a fixed plate distance, which is defined at an initial
stage of the project according to the product size and cannot be
modified once the freezer is built. This distance is calculated to be
able to carry out the loading and unloading operations very easily
(there is a margin between the product and the plate above).
Trays can be loaded without stop, with plates at working temperature
(the evaporation temperature is normally between –35°C
and –40°C).
The product is loaded inside 600 mm trays which have a handle
(the tray length coincides with the plate width), so that the operator
can easily reach the entire useful surface. The cycle time will
depend on variables such as product, refrigeration equipment or
the loading method, and therefore it must be defined according to
the real working conditions. In any case, it is minimum compared
to traditional IQF systems (by forced air), as the product is frozen
by direct contact with the plate.
The loading and unloading operations are done simultaneously,
replacing the frozen product with fresh product immediately. The
only interruption to this process is the defrosting: its periodicity will
depend on the environmental conditions, product, etc. but, in any
case, it will be very fast thanks to an extremely short circuit.

and refrigeration equipment is supplied with all the refrigerating
and electrical connections).
