Abstract

The invention relates to the field of processing products by drying and allows to improve the performance of the dryer and to increase the uniformity of drying when used as a source of drying agent for household electroconvector (EC) of a batch dryer for food products. The walls of the drying chamber (SC) 1, located above the EC 2, in the lower part are bent inward with the formation around the EC of 2 annular yellow

Description

one

The invention relates to the technology of processing products by drying and can be used for drying mushrooms, ruktov and vegetables.

The purpose of the invention is to improve the operational characteristics and increase the uniformity of drying when using as a source of drying agent for household electric convectors of a batch dryer for food products.

Figure 1 shows a batch dryer for food, a longitudinal section; figure 2 is the same, side view; Fig. 3 shows an embodiment of the dryer.

The batch dryer for food products contains a drying chamber 1 located above the source of the drying agent, made in the form of an electric convector 2 and separated from the latter by a visor 3, as well as perforated trays D having overflow openings 5 of adjustable section installed in the chamber 1. The walls of the chamber 1 in the lower part are bent inward to form an annular groove 6 around the electric convector 2, branch pipes 7 are embedded in the bypass holes 5 of the trays 4 and are arranged in a quantity that gradually decreases from the lower tier to the upper one. The visor 3 has the shape of a double slope, and on the inner walls of chamber 1 there are horizontal wavy-shaped protrusions 8.

The device also contains fasteners, made in the form of clamps, shell 10 and clamping screws 11. The dryer also contains a door 12, an absorber filter 13,

Krshaku 14 and bore adjuster 15 of the upper nozzle 7.

The device works as follows.

The camera 1 is mounted on the electric convector 2, the latches 9 enter the grooves of the shell 10, which is fixed on the body of the electro-vector 2, then the clamping screws 11 are tightened,

The trays 4 are filled up to half the height of the nozzles 7 with products prepared for drying and are pushed through the door 12 along the guides to the chamber 1. The drying agent — warm air — passes from the electro-convector 2 through the holes 5 of the trays 4 and its excess goes through the nozzles 7. Regulator 15, the flow rate of the drying agent through chamber 1 is varied. Gaseous pro- ducts and drying products are absorbed by the absorber filter 13. Visor 3 and ring gutter 6 prevent the drying products from accidentally entering the electric convector 2. The location of the nozzles 7 is in quantity vayuschem nihshego from the upper tier, provides a uniform distribution of the drying agent rusam.

Horizontal protrusions 8 of a wavy shape on the opposite inner walls of the chamber 1 provide the ability to install skewers, and the waves of the protrusions of nearby Rus are shifted relative to each other.
