Why Vacuum Cooler?
Vacuum Cooler is an English term meaning "cooling by vacuum application"..
The principle of operation Vacuum Cooler is based on the rapid evaporation of part of the product's moisture when subjected to a decrease in pressure inside an airtight chamber.
This method is an effective rapid evaporative pre-cooling treatment for prolonging the life of treated products by reducing their post-harvest thermal deterioration.
The units Vacuum Cooler are designed to cooling vegetables with fiber from room temperature to near freezing temperature. Part of the water evaporated during the process is condensed with a cooling coil located inside the chamber.
Nuestras máquinas Vacuum Cooler cool the products in a fast and homogeneous way, avoiding the growth of microorganisms that deteriorate their quality and extending their life by 4 to 6 times more than their normal life, favoring conservation fruits, vegetables and flowers, among others.
First treatment before placing the product in cold storage.
- Introduce the cold quickly into the heart of the piece (20-40 min).
- Prolongation of the shelf life of cold preserved products.
- Estabilidad de temperatura dentro de la cámara.

Vacuum Cooler Operating Cycles and Processes
The operating cycle of the Vacuum Cooler installation is as follows:
The product is packaged, palletized and placed on pallets and, by means of conveyors, is introduced into the airtight chamber where the special production is to take place. vacuum.
The chamber is equipped with actuated doors that automatically close and open to allow the chamber operator to enter the chamber. pallets automatically.
The pumps create a vacuum inside the chamber and the surface water of the product undergoes a rapid evaporation, which causes the product to undergo a rapid coolingThe amount of water lost is not sufficient to affect the quality and life of the water. The amount of water lost is not enough to affect the quality and life of product storage.
A steam condenser is installed to condense the steam extracted from the product. refrigeration system inside the chamber.
The pressure inside the chamber is reduced from the presión atmosférica to 7 mbar for each work cycle.
Consequently, the temperature of the water containing the product will be reduced from the ambient temperature to 25ºC to 2ºC according to the water vapor tension curve.
Water vapor stress curve under vacuum
The duration of each cycle will depend on the product to be treated.
Vacuum cooling is used only for products with a high surface/volume ratio, such as cabbage, lettuce, celery and other leafy vegetables, in which evaporation and complete cooling is possible in a reduced time with high quality.
Some products suitable for cooling in Vacuum Cooler:
Likewise, product cooling cycle times vary depending on the product to be cooled. Some examples would be:

Safety in Vacuum Cooler Installations
Moelco Levante advocates a safe and environmentally friendly design and construction of its machines. Therefore, the Vacuum Cooler can be considered as a safe and environmentally friendly machine, as it does not emit toxic emissions into the environment.
All possible risks are taken into account in the manufacturing process, which is why fixed and movable guards are installed to protect the operator from hazards that could occur during machine operation, such as trapping in the motors and moving transmission and electrical elements, etc.
It has an emergency stop located on the control panel, integrated guards and the corresponding pictograms indicating the risk.
The electrical installation of the machine complies with R. D. 842/2002 Low Voltage Electrotechnical Regulation and subsequent complementary technical instructions on low voltage electrical installations, as well as with R.D. 1580/2006, which transposes the directive on Electromagnetic Compatibility 2004/108/CE, and with the UNE-EN 60204-1 standard, Safety of machinery.

Benefits of the Vacuum Cooler System
Biological benefits in application to vegetables:
Rapid cooling reduces enzymatic oxidation and the action of spoilage microorganisms, preventing the appearance of external wilting.
Commercial benefits:
In average terms, a vegetable processed by a system can be considered to be Vacuum Cooler acquires a half-life of 30 days. It can be said that a process of Vacuum Cooler contributes:
- Considerable increase in the shelf life of treated plants.
- Eliminates overloading of the cooling demand of the refrigerated chambers.
- Possibility of reducing the stock of stored product.
- Freshness contribution to the pieces, maintaining the initial qualities of the vegetable.
- Possibility of refrigerated transport distance, increasing the commercial market.
