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
