What is vacuum evaporation?
Vacuum evaporation is a technique that manufacturers often use to maintain food and beverage products. When food or drinks evaporates, they can usually be maintained for a longer period of time without spoiling. Vacuum evaporation can also be used to concentrate these products. For example, evaporated milk is basically fresh milk that evaporates vacuum, resulting in a richer creamy product that has a longer shelf life than fresh milk. In other words, evaporated milk is a concentrated dairy product. The most visible benefit is the protection of the product. For example, consider canned fruits and vegetables that are subject to vacuum evaporation. These canned goods take much longer than the items of fresh products that can spoil within a few days of purchasing from food store. And volume. This means that they usually require less packages. In addition, their smaller size can make cheaper for companies for transport and storage. For example, a freezing concentrateThe orange juice not only has a longer life, but also requires less packaging and less storage space than a fresh bottle of orange juice.
Vacuum evaporation system can be used to maintain or condensation of food and beverage products. Vacuum vapors are devices in which liquids evaporate from a low density substance to create a high density and more concentrated product. Many food and diary products require high vacuum evaporation techniques to achieve a usable, long -term end product.
Vacuum evaporator usually contains three key elements. The first element is the heat exchanger that transmits heat from steam to food product. The second element of the separator of vapor and liquid and the last element is the vacuum manufacturer. This is usually operated by a steam ejector or mechanical pump.
type of vacuum evaporator used for specificallyThe type of food or beverage product will vary depending on the liquid characteristics of the product. The factors to be considered may include the properties of concentrates, foaming, impact on temperature and timing and recovery of quality and taste. Costs are also often a factor for manufacturers.
Vacuum evaporation also occurs outside the food industry. In this context, it is often referred to as vacuum thermal evaporation and is used in semiconductor, microelectronics and optical industry. In general, vacuum thermal evaporation is a method of storing thin films on cold surfaces.
