Abstract
In a device for producing snow, a vaporizer roller (1) is rotatably mounted in a housing pan (5) and a rotary distributor (7) for introducing a coolant is arranged in the evaporator roller (1). Nozzles (8) for spraying water and air onto the evaporator roller (1) and a scraper (3) for smoothing and a scraper blade (2) are further provided. The device enables a temperature-independent production of snow.
Description
1 , . Device for producing snow The invention relates to a device for producing snow.
The product produced with known devices is "flake ice", which, however, is not or is only partially suitable for some applications, for example, for the cooling of the human body after a sauna visit.
Such devices are described, for example, in DE 10 2008 029695 B3, WO 96/35913 Al, DE 940 227 C and US 277 797 A.
This flake ice is a technically manufactured form of ice.
Flake ice consists of individual ice flakes with an irregular, shard-like, slightly wavy shape. The ice flakes are 1 to 2 mm thick and have a temperature of about -7 C.
Flake ice can be used to cool food, in particular fish, or to produce food.
When manufacturing with a flake ice machine water is filled, for example, into a cylindrical container, in which a stainless steel roller is located and the wall of which is cooled via a strong cooling machine. Ice forms on the cylinder wall, which passes upwards through a conveying screw and is scraped off by a scraper and then falls into a reservoir.
Another manufacturing method works via a horizontally arranged evaporator roller which rotates in a water bath. With each revolution, water freezes on the strongly cooled evaporator surface and chips off on a scraper.
In contrast, there are snow cannons, which as a rule produce snow and not ice, but can only be operated successfully in a (very) limited temperature range. For example, the snow propeller is technically known: Central element in this case

Another manufacturing method works via a horizontally arranged evaporator roller which rotates in a water bath. With each revolution, water freezes on the strongly cooled evaporator surface and chips off on a scraper.
In contrast, there are snow cannons, which as a rule produce snow and not ice, but can only be operated successfully in a (very) limited temperature range. For example, the snow propeller is technically known: Central element in this case
2 , is a propeller , which produces a strong airflow. The nozzle holder is located around the pipe exit with mostly several rings. The outer nozzles are usually designed as mixing nozzles (water and compressed air) for the production of snow cores, the inner ones mostly as pure water nozzles. The mixing or nucleator nozzles produce small ice crystals as crystallization seeds.
The amount of water droplets must be adapted to the external weather conditions such as temperature and humidity and the throwing range to achieve optimum characteristics of the technical snow. The water droplets contained in the air stream emerging from the propeller cannon partially evaporate in the dry winter air, which cools the droplets. If the freezing point is reached, they crystallize on the crystallization seeds. The drier the ambient air, the better the cooling process. For example, this process thus works at a relative humidity of 30% already at 1 C above zero, at 80% relative humidity, in contrast, below -3 C is required.
Compared with the prior art, the invention has set itself the goal of providing a device with which a production of a product independent of temperature is made possible, the product being largely similar to natural snow.
The object of the invention also includes the provision of a device which has, in addition to the production of snow or a snow-like product, smaller dimensions than conventional snow cannons and therefore can be well used in ski halls, sauna and wellness landscapes and industrial applications.
This is achieved, starting from a device in which an evaporator roller is rotatably mounted in a housing pan and a rotary distributor for introducing a coolant is arranged in the evaporator roller, a liquid feed to the evaporator roller
