Description

The invention relates to the meat industry, namely to devices for air distribution in the drying chambers of meat products, such as sausages.

An air distribution system in the drying chambers of meat products is known, including air ducts made in the form of perforated panels located on the side walls of the chamber opposite one another.

This system, despite the design complexity, bulkiness and high intensity, does not ensure uniform distribution of air throughout the chamber.

Closest to the invention by its technical essence is an air distribution system in the drying chambers of meat products, comprising air ducts arranged at the corners of the chamber with well-shaped outlets along their length having oppository openings 2.

A disadvantage of the known construction is that, 4to, it does not ensure uniform distribution of the heat transfer medium over the chamber volume.

The purpose of the invention is to increase the uniform distribution of the coolant through the chamber volume.

This goal is achieved by the fact that in the air distribution system in the chambers, drying the meat products, including air ducts located in the corners of the chamber, with well-shaped outlets along their length, having opposite openings, air ducts are located in diagonally opposite corners of the chamber and are designed so that the air duct side with the hole-like outlets, perpendicular to the diagonal plane passing through these angles, the hole-like outlets being provided with guides for distributing the air flow installed inside the air uhovoda at an angle to the plane of opposed openings uvelichivayuschims the end of the duct.

Such an arrangement of air ducts with well-shaped outlets allows completely to exclude the presence in the chamber volume of both stagnant zones and zones with increased air mobility. At the same time, due to the high turbulence of the inlet jets from the well-shaped outlets, the most favorable conditions of the product bottoms are provided.

Installing guides to distribute the air flow at an angle to the plane of the opposed openings of the outlets, which increase towards the end of the duct, ensures uniform air flow along the duct length, regardless of the volume of air supplied to the chamber and its velocity in the duct. Moreover, the uniformity of the passage of air through all lunkoobraznye. Outlets are provided both when the air duct is operating on the inflow and when it is working on extracting air from the chamber, which allows 5. to organize reversible air movement. FIG. Figure 1 shows the air distribution system in the drying chambers of meat products, a general view; in fig. 2 - air duct.

0 The air distribution system in the drying chambers of the meat products includes air ducts 1 installed in the diagonally opposite corners of the drying chamber 2 of the meat products. Moreover, the air ducts 1 are designed in such a way that the side 5 by 3 with the hole-like outlets 4 is perpendicular to the diagonal plane passing through the corners of the chamber 2, in which air ducts are installed. Inside the air ducts 1 iod angle to the plane of the opposite

The Q holes 5, increasing towards the end of the duct, have guide rails 6 for air distribution.

The proposed air distribution system in the drying chambers of the meat products works as follows.

5Air from the fan (not shown)

It is fed to Kaiviepy 2 through one of the ducts 1, for example the lower one, and is removed from the chamber 2 through the duct 1 located in the upper corner. With the help of

the guides are provided both by the uniform flow of air into the chamber 2 through all hole-like outlets 4 of the air duct, working for the inflow, and by the uniform removal of air from the chamber 2 along the entire length of the duct working on the exhaust.

Thanks to the well-shaped outlets 4, which provide an opening angle of the jets of air flowing out of them close to 120 °, and to the sides with the outlets perpendicular to the diagonal plane passing through the corners of the chamber 2, in which the air outlets 1 are installed, uniform air distribution is achieved throughout camera volume.

If it is necessary to provide reversible air distribution, 5 s alternate operation of the air ducts 1 is carried out on the inflow, then on the exhaust. With a significant volume of chamber 2 in its other corners, additional air ducts can be installed.

P) the air distribution system in the drying chambers of the meat products allows for improving the uniform distribution of the heat carrier (air) over the chamber volume, which ensures the uniformity of temperature, humidity and speed fields of the heat carrier in the chamber, and ultimately improve the quality of the processed products and intensify the drying process.
