Door Opens Fan Stops Refrigerator and Freezer - Procool

A: Yes, if it’s a freezer (inside -18 C). But it is not a must for refrigerators (inside 2~8 C). That is because the inside temperature of the freezer is lower than that of the refrigerator, the cooling time is longer and the energy consumption is higher. Therefore, our upright freezers come standard with the function of “Door Opens ...

Evaporation During Cooking: Technique and Information

Evaporation During Cooking: Technique and Information

But before we dive into its cooking applications in too much depth, let’s first go over the basics of what evaporation is. In short, it’s the process of a liquid entering into a gas state—turning into vapor. As water evaporates when you’re cooking with heat, it turns into steam in the air. Over time, this lessens the volume of water in ...

Evaporation Process. If we view the evaporation process in two steps (with dS=dS1+dS2), with the first step consisting of a reversible phase transition from liquid to vapor at the surface (with dS1=0), and a second step involving the irreversible mixing of the released vapor with the unsaturated air of the atmosphere (dS20), we then gain the following expressions for the two …

The process of evaporation involves the removal of water (or other solvents) from a product or wastewater stream by adding energy to change the physical state from a liquid to a gas. In an efficient system, this energy is then recaptured as the gas (or vapor) state is condensed back to the liquid state. With a keen eye towards the customer’s ...
