Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·Drying is a crucial unit operation within the functional foods and biopharmaceutical industries acting as a fundamental preservation technique and a mechanism to maintain these products bioactive components and nutritional values The heat sensitive bioactive components which carry critical quality attributes necessitate a meticulous selection
This is done by applying a low temperature and vacuum to the sample The water in the sample forms ice crystals that are then sublimated shifting from solid directly into gas As a result the water content leaves the sample without passing through the liquid phase 32°F for up to several years while freeze drying foods remove the
2 ·Working Principle of Vacuum Dryer Vacuum Dryer involves the indirect application of heat or steam to the material tinder evacuated conditions vacuum is created inside the dryer Under such conditions the moisture evaporates at a temperature lower than its boiling point Hence drying occurs in a shorter period compared to normal tray
·Stages of drying The phenomenon of drying can be discussed under two periods Constant rate period and ; Falling rate period; Constant rate period When food in the dryer is applied with heat water moves from the interior of the food at the same rate as it evaporates from the surface and the surface remains wet until the certain critical moisture
·The chapter presents studies from end the past century when microwave vacuum drying of foods started to be studied until nowadays The evolution of this technique can be confirmed by technical advances introduced over the years such as the use of product rotation power intermittency control of product temperature osmotic pretreatment and
