The XB570L controller is dedicated to blast chiller applications and gives a solution
to HACCP system.
With the XB570L, food is rapidly cooled (both at +3°C and at –18°C) immediately
after it has been cooked, to avoid the proliferation of bacteria that occurs when
food is allowed to cool naturally or in a normal refrigerator.
Ease of use and complete management of each blast chilling phase is guaranteed
by 4 cycles that can be adjusted to suit any type of food. It is possible to display the
temperature of either the air or the food insertion probe.
The hygiene of the blast chiller is guaranteed by an extra configurable output for
sterilization by means of ultraviolet rays.
The optional XB07PR printer can be connected to the XB570L controllers to provide
the user with a written report of all the main data required: cycle start and stop
times, duration, the temperature of the product or the coldroom, all at regular
intervals, via an internal time clock.

The XB570L has 4 different soft and hard chill cycles in it’s memory. These can also be modified by the User.
Each cycle is defined with independent time and temperature parameters to set each control phase and can be combined even with the hold phase.
The four cycles are directly selectable from the keyboard. The control of each cycle is carried out using the insert probe or by time duration.

Each cycle (Cy1, Cy2, Cy3 and Cy4) can be programmed
with three different phases according to the food
type.

• First phase: hard chill

Limits bacteria reproduction during the initial phase
(from high temperature down to 2 °C). During “Hard
Chill”, both compressor and fan are always “on” until
the end cycle temperature is reached.

• Soft chill phase

Reduces the variation between the surface and core
temperatures of the product. During “Soft Chill” the
temperature of the room is regulated by the ambient
probe: compressor is cycled to maintain a particular
air temperature.

• Freezing cycle phase

Freezes the product in the shortest possible time.
During the “Freezing Cycle” both compressor and fan
are always on until the end temperature is reached.

• Holding phase

The holding phase maintains the final temperature
reached by the chilling cycle.
