5.1 MATERIALS AND CHILLING SOLUTIONS
The areas in contact with the product are made of stainless steel.
Refrigerated units use HFC type refrigerant fluid allowed by current legisla-
tion. The type and quality of gas used are indicated on the plate.
5.2 ELEMENTARY SAFETY STANDARDS – RISKS
The Chiller has no dangerous corners, sharp and cutting surfaces or pro-
truding parts. All safety
guards on moving parts or electrics are screwed to the cabinet. These
guards avoid any form of accidental contact with parts that present a risk to
the user. Always respect safety standards:
• Do not touch the Chiller with wet hands or feet
• Not use the Chiller barefooted
• Do not poke screwdrivers, cutlery or other objects between the safety
guards mounted on moving parts
• Before cleaning or servicing the Chiller lock-off the power supply.
Carefully follow and adhere to the instructions given in this chapter to gua-
rantee working efficiency and safety when the Chiller is in use.
CAUTION: When transporting or moving the Chiller to the insta-
llation site do not push or drag it, lift it and position it on a trolley to avoid
overturning.
5.3 LOCATION
Locate the Chiller in a ventilated area distant from heat sources such as
radiators, air conditioning units, deep-fryers and ovens. Make sure the
Chiller is located at a distance not less than 10 cm from the back wall to
permit a good cooling effect for the various components.
To maintain the correct internal temperature, the ambient temperature must
not exceed +32°C Adjust height and levelling using the support feet and
also check the door closes.
If the Chiller is not perfectly level working efficiency and condensation flow
may be affected. Remove the PVC protective film on both sides of the
Chiller.
The machine should be situated allowing adequate space around it so that
proper air circulation is assured.
5.4 CONNECTING TO THE POWER SUPPLY
Connect the unit only to energy sources properly earthed.
Do not damage the power cord (danger of electric accident). If it is dama-
ged, it has to be replaced immediately by a qualified electrician from the
assistance centre.Install a safety switch in case of fault currents with a
specific protection for persons (30mA) on the power supply control panel.
CAUTION: the manufacturer shall not be held responsible for dama-
ge or accidents caused by negligence due to the non-observance of the
recommendations and regulations given or of the local governing standards
and laws regarding electrical safety.
6 ADVICES FOR A CORRECT USE OF THE EQUIPMENT
6.1 OPTIMIZATION OF THE CYCLES
PRE-COOLING
Pre-cooling is highly recommended before carrying out a chilling or rapid
deep-freezing cycle to pre-cool the cell in order to reduce working times.
CORE PROBE (optional)
The core probe, if it is present (optional), shall be properly positioned in
the core of the thicker portion of product. Its point shall neither come out
nor touch the pan. The probe shall be cleaned before starting any cycle, in
order to prevent contaminations.
LIDS AND CONTAINERS
Do not cover pans and/or other containers with lids or insulating films. The
more the product's surface gets in contact with the air circulating in the
cell, the less it will take to chill and deep-freeze it. Do not use cups or pans
deeper than 40 mm.
POSITIONING OF THE PRODUCT
Do not superimpose layers of product one upon another and make sure
that they are never thicker than 50 mm.
Do not overload the unit beyond the quantity recommended by the manu-
facturer.
Allow a sufficient space between the pans in order to permit the proper air
circulation. Do not put too many pans on one side of the unit, but distribute
them equally.
CONSERVATION
The chilled and/or frozen product shall be covered and protected (film,
airtight, hermetic sealing). The probe must be cleaned before each cycle
to avoid contamination.
6.2 PREPARATION OF THE MACHINE
It is necessary to clean the chilling chamber optimally before starting to
work.
The blast chilling/blast freezing rate depends on the following factors:
• shape, type and material of the containers used
• use of lids on containers
• food characteristics (density, water content, fat content)
• initial temperature
• thermal food conduction
Blast chilling time and rapid blast freezer are based on the type of product
being treated.
It is recommended to use the full speed cycle for all dense or large dough
foods and in any case never exceed 3.6 kg (for GN1 / 1, EN1 / 1 or 60x40)
or 7.2 [kg] for loads (for GN2 / 1, EN2 / 1 or 60x80) and the thickness of 50
[mm] during negative killing and 80 [mm] during positive killing.
The low speed cycle is suitable for delicate products such as vegetables,
creams, spoon desserts, or reduced-thickness products.
In any case, check that the positive cutoff cycle up to +3 [° C] to the product
core does not use a time of more than 90 minutes and that the negative
cutoff cycle, up to -18 [° C], do not exceed 4 hours. It is necessary to pre-
cool the working chamber before starting the positive cut and / or negative
knockout cycle and it is advisable not to cover the food during the cycle in
order not to increase the time needed.
When the thickness of the product allows, always use the heart probe to
know the exact temperatu- re reached at the heart of the product and not
to interrupt the cycle before the positive +3 [deg.] C temperature is reached
and -18 [° C] in case of negative chilling.
6.3 SWITCH OFF THE MACHINE
It is always advisable to perform a defrost cycle at the end of the use of
the blast chiller, both to dry the chamber and to prevent any condensation
water from stopping on the fan/s and damaging it.
