V. Equipment characteristics

GOLDSTEIN VISION is a universal device for preparation of dishes. It

enables the user to prepare a complete menu. It is possible to carry
out all kinds of thermal processing of food in the GOLDSTEIN VISION
combi-steam oven, such as roasting, frying, grilling, stewing, steaming,
cooking at low temperatures, low-temperature overnight
roasting/baking. One of the advantages is food-processing with low
consumption of water and oil, exclusive of smell transfer when
processing two different dishes, preservation of vitamins and minerals,
great power, water, place and time saving. Due to the possibility to
control humidity in the cooking cabinet there are great savings in the
weight of the food processed.

It is also possible to use the combi-steam oven as proofing
compartment, to preserve and dry fruits or other technological
processes. All such processes are programmable and can be carried out
regardless of the personnel. Use of the temperature probe is another
advantage, especially with high-temperature-sensitive foods (roast
beef).

If using the equipment reasonably, you can save place and time,
otherwise necessary for single-purpose devices for individual
production processes.

Thermal processing of food takes place in the cooking cabinet where
hot air is circulated evenly by the ventilation fan. The air can be
moistened by generating steam. The humidity is controlled
automatically according to set value and operation. During steam
operation the humidity is set to 100%, in combined operation it can be
varied.

All processes are automatically controlled by a microcomputer, inbuilt
in the CPU of the combi-steam oven.

The cooking itself can take three different forms:

Product plate of the combi-steam oven is located on the upper right
side. A copy of the plate is located inside the device, on the left side.
The plate contains the following information: the manufacturer,
technical data regarding the equipment, i.e. type and model,
construction number, year when manufactured, important data
regarding type of power supply, energy input, weight and protection
from water. The label also includes CE and ESC marks, confirming
that the equipment complies with all requirements of CSN, EN, IEC

and government ordinances.

• Less experienced users can use EASY COOKING which will

recommend and set suitable values according to the dish
prepared. EASY COOKING uses technology which has been
developed by a team of GOLDSTEIN expert chefs and
includes all kinds of food processing that can be done in a
combi-steam oven.

• Another option is to use pre-set programs or create own

programs. 1000 programs (recipes) can be entered in the
combi-steam oven memory and they can contain up to 20
steps. Each step can include different parameters and
different cooking mode. The advantage of such programs is
the fact that they are carried out automatically and when
keeping the same input conditions the same quality result
can be reached every time.

• The last option is the setting of al the parameters manually.

Only an experienced user should use this option, setting the
parameters of cooking process exactly according to their
requirements.

Advantages

• rational food preparation

• preservation of vitamins and minerals, microelements and

taste

• weight-loss reduction

• Processing using minimum amount of water and oil

• no smell or odor transfer during concurrent food-processing

• saving of energy, water, oil and time compared to common

technologies

VIII. Recipes

OPERATION MANUAL FOR GOLDSTEIN VISION COOKING CENTRES

GOLDSTEIN Vision combi-steam ovens offer the use of pre-set
programs to prepare a large number of dishes. expert chefs have
prepared for you typical recipes for food preparations so that all the
quality and sanitary standards and HACCP norms are met.

Special attention was paid to the maximum use of the combi­steam oven features, maximum extraction and quality of dishes when
designing the programs.

A team of Goldstein expert chefs drew inspiration from everyday
experience of chefs in gastronomic establishments and created a
group of programs, which contain most of the common needs of all
types of gastronomic establishments so that the operation of the
combi-ovens was less complicated.

Great advantage of the combi-steam ovens is the possibility to
use pre-set programs so that the final product complies with the
gastronomic establishment, national, regional and local customs and
taste and experience of the chefs.

Matter of fact of the Goldstein combi-steam ovens is the
possibility to create own programs and their consequent changes with
the maximum use of the combi-steam oven’s features, entry of
created programs into typical groups so that the experience,
inventions and creativeness of the chef is used when creating
gastronomic and culinary specialties. It is up to the chef’s imagination
and experience which technology, steps or functions they use.

The program creation is not limited by number of steps and
enables the use of all available functions and procedures. It is possible
to define typical groups of dishes for created programs, where
programs can be stored, moved, deleted or changed and added
further steps.

You can use your USB flash stick when working with „Recipes“
section. You can choose recipes or categories and copy these to your
USB or to your combi steamer.

It is also possible to store most often used programs to
“Favorites” and use the option of quick access to the most important
and favorite programs.

The advantage is also the “Last ten” where the last ten used
programs are stored for quick use in everyday practice.

“Programs” allows you to use the combi-steam oven in its
maximum capacity, with ease of operation and enables the products
to be prepared repeatedly to the highest quality.

IX. Easy cooking

GOLDSTEIN VISION combi-steam ovens offer a unique

technology Easy Cooking which enables even the less experienced
chefs to obtain excellent results. It is not necessary to know in detail all
the cooking process stages and set individual steps. The “Easy cooking”
system is sort of a guide which recommends and sets suitable
technology according to the type of dish and required result.

The operation in “Easy cooking” mode is limited only to the choice
of dish, or gentle “tuning” of the intensity of roasting/baking and color
of the surface and following pressing of the “Start” button. The rest will
be done by the combi-steam oven for us.

The fact that at every stage we can enter the cooking process and
adjust the offered parameters so that the result meets our expectations
is obvious.

If you are satisfied with your final product, it is possible to enter
the selected technology among your favorite programs and use it again
any time to obtain as quality result.
