Techfrost JOF ONE Owner's Manual

Thank you for choosing TECHFROST products. We are certain that you will be more than satisfied with their
performance. To help maintain efficiency and performance please follow the guidelines set forth in this manual
describing the correct use and maintenance of the Blast Chiller Freezer.

1i: TYPE OF USE AND LIMITATIONS

This Blast Chiller Freezer has been designed for chilling and preserving food.  It rapidly lowers the temperature
of  cooked  food  and  specialty  frozen  desserts,  preserving  quality  and  assuring  ultimate  product  freshness.  Any
other  use  is  considered  improper  and  incorrect.    This  Chiller  must  not  be  installed  outside  and  or  in
environments  subject  to  weather  conditions.    The  manufacturer  declines  all  responsibility  for  uses  other  than
those given in this manual.

1ii: CHARACTERISTICS OF THE MACHINE

The machine, to which this handbook refers, is a blast chiller/freezer which is completely constructed of
stainless steel AISI 304. It will continue working until reaching

-40 °F

. This machine is capable of quickly

tempering the heart of the cooked products from +158ºF to +37.4ºF during blast chilling and from +158ºF to -
0.40ºF during blast freezing.  This thermal shock, keeps bacteria from spreading without altering the
organoleptic conditions or modifying the product’s quality.  Through the use of this process, hygiene, security,
and product quality is maintained.

Features of the blast chiller include:



Indirect system of air circulation



Constant temperature from shelf to shelf



Advanced cooling system for a quick, cold penetration to the product’s core



Maintenance of a high humidity rate in the chilled product (80%-85%) thus avoiding drying or
dehydration, eliminating the risk of weight loss



Excellent thermic conditions during transfer to the conservation cell

A product is at peak quality at the point that it is taken from the oven, batch freezer or other production process.
The high temperatures reached by the oven act to destroy microorganisms without altering the product’s quality.
The molecular structure of a frozen dessert is at its best when first extracted from the production machine. You
can  keep  this  high  quality  level  unchanged  by  starting  the  chilling  process  immediately  after  production.  The
blast  chiller  acts  to  lower  the  temperature  rapidly,  preventing  external  drying  and  early  deterioration  of  your
product. These low temperatures also block bacterial proliferation.

The blast chiller is a professional instrument that closely follows regulations regarding the thermal treatment of
gastronomy, pastry, and ice cream products, before and after cooking. It facilitates application of the

HACCP

System

(Hazard Analysis Critical Control Point) and compliance with ISO9000 norms.

The passage to conservation at the pre-defined temperature follows the chilling or deep freezing cycle
automatically.

AIR STERILIZATION (accessory by request) is obtained by, the production of agglomerates of active oxygen
atoms. These atoms destroy bacteria, viruses, mildew spores, odor molecules, etc.

1iii: TESTING

Every Techfrost Chiller is thoroughly tested before shipping. Testing includes a visual inspection, an electric
test, and a functional test. Final testing is certified for the relevant documentation (please refer to the enclosed
appendixes).

GENERAL SAFETY

2i: GENERAL SAFETY STANDARDS

The Chiller in question is manufactured conforming with the European Directives relevant to low tension

73/23-

93/68/EEC,

and electromagnetic compatibility 89

/336/EEC;

EN60335- 1, EN60335-2-24, EN55014, EN61000-

3-2, EN61000-3-3, EN55104.

2ii: LOCATION REQUIREMENTS

It is necessary that electrical supply to the freezer be provided as specified on the data plate of your Techfrost
freezer. Each freezer comes with electrical cord and power connector as required.



The chiller and its control board should only be operated by adults.



Installation and any other operation (including a possible extension of the power cable) must be carried
out by

authorized personnel

only.



Maintenance and service have to be carried out by qualified technicians. Only factory replacement
parts should be used for repairs.



Do not attempt to modify the chiller yourself; the operation could be dangerous.



In order to avoid the risk of over-heating of the compressor and consequent damage, it is crucial to
allow sufficient air circulation around the machine.



The chiller should be placed so that there remains sufficient space for air circulation in the back (at
least 10 cm or approximately 4in.).



While installing or transporting the unit, take care in ensuring that the cord is not crimped or kinked.
Before any cleaning or installing operation, remember to switch the machine off and disconnect the
plug. Make sure you do not pull the cord.



The deep-freezing system, placed on the back and inside the machine, contains a refrigerant solution.
Do not use sharp objects in the vicinity of the evaporator, cooling plate, or near the pipe coils (located
on the back and inside the chiller). The accidental perforation of the system could cause damage to the
unit.



Wait for at least 30 minutes before connecting the plug to the power point after sitting freezer in place.
If the chiller has been transported in the horizontal position, be sure to keep it vertical for at least four
hours. This allows the oil contained in the compressor to be transferred back to its original location.



WARNING! Do not keep explosive gases and liquids or glass bottles in the machine. Doing so may
result in damages to persons or things.



When the

“DEEP-FREEZING”

process has concluded, dry gloves or cloths should be used to remove

containers from the machine.



Do not open the machine door while executing its working cycle. Doing so may prevent cycle
completion.



The constructor is not liable for damages arising from improper use or installation, connection to non-
authorized equipment, use of non-original fittings, or tampering by non-authorized personnel.

CAUTION: The Blast Chiller/Blast Freezer must be connected to an electrical supply source that matches
the data plate on the machine. Make sure it is level and always use qualified personnel to install, repair
and service your Chiller.
