Abstract
In the work, the specified features of the temperature regime in the drying chamber showed that when the coolant moves in the chamber, both the temperature and humidity regime of the air and the temperature and drying rate of the product change, and the drying rate is almost proportional to the increase in air humidity. Based on the studies carried out, simplifications were obtained in describing the drying process, which makes it possible to more reasonably carry out engineering calculations in the design of the dryer, in particular, to set the input and output air humidity, to determine the length (or height) of the drying chamber.
Highlights
The results of experimental studies of the process of the essence, the features of drying various products in the chamber and the open air are considered
The drying rate is a function of the moisture content, which is variable along the length of the chamber
The loss of heat by air in some areas is about 10%, and there is a fairly strong change in the drying rate and moisture content of the product
Summary
The results of experimental studies of the process of the essence, the features of drying various products in the chamber and the open air are considered. The paper presents a method for calculating the drying rate and its change along the length of the chamber. This example does not consider the change in the moisture content of steam in the air and its effect on the drying rate. The drying rate is a function of the moisture content, which is variable along the length (height) of the chamber. In this regard, to analyze the issue, consider the problem of changing the drying rate of the product along the length (height) of the chamber (see Figure 1)
