Description

I

The invention relates to the food industry, namely to the drying, technology.

Dryers are known for dry and granular products, such as casein, consisting of a drying chamber installed inside it one above the other gratings with central openings for the passage of the product, located above each scraper grate and distribution disk and drive shaft of distribution disks mounted on camera axis.

The purpose of the invention is to increase the drying efficiency and to provide the ability to control the performance of the dryer.

For this, in the proposed dryer, the distribution discs and scrapers are rotatable at different speeds, while the scrapers are mounted on a hollow shaft, which is located concentrically relative to the shaft of the discs.

The shaft of the disks and the shaft of the scrapers are made of separate elements connected together by the driving mechanisms, and the number of elements corresponds to the number of grids.

The body of the drying chamber is made of a series of sections, interconnected by clamps. The number of sections corresponds to the number of grids.

FIG. 1 shows schematically the proposed dryer; in fig. 2-drive mechanism, connecting the neighboring elements of the shaft of the disks and the shaft of the scrapers; in fig. 3- section of the drying chamber. The proposed dryer consists of a drying chamber 1, the casing of which is assembled from a series of sections 2 installed inside the chamber (in each section) of gratings 3 with a throat, 4 mounted along the axis of the chamber of the drive shaft 5 with distribution discs 6, a hollow shaft 7 hinged scrapers 8 attached to it and mounted concentrically with respect to shaft 5, as well as from a device for heating and supplying air. Scraper 8 and distribution disc 6

mounted above each grid, and they are made with the possibility of rotation in different directions and with unequal speeds.

Shafts 5 and 7 consist of interconnected driving mechanisms of the elements. Their number corresponds to the number of sections 2. Thus, the substance is assembled from separate sections, the number of which is determined by its capacity and the type of product being dried.

The shaft 7 is mounted in ball bearings housed in bosses 9 and attached to the ribs 10. Each scraper consists of a roller and working elements mounted on it // alternating with rings 12 and connected to shaft 7 by a hinge 13 and frame M.

The drive mechanisms connecting the shafts consist of two led 15 and 16 and leads with fingers 17 and 18.

The drive shaft 5 is carried out from the electric motor 19 through the front conveyor gear 20, and the drive shaft 7 from the electric motor 21 through the gearbox 22 and the chain drive 23.

Both actuators are installed inside frame 24. The dryer has a scraper 25 for unloading. It is mounted on the bracket 26, fixed on the shaft 7. The dryer is equipped with a crusher 27, to the chamber of which the outlet chute 28 is connected. A cone-shaped chute 29 is installed under the lower grate.

The device for heating and supplying air comprises a fan 30, a pipe 31 and a heater 32. The outlet of the latter by the air duct 33 communicates with the lower section of the dryer.

Exhaust duct 34 is connected to an outlet in the upper section.

The drying chamber has a cover 35 with a neck 36. The sections of the dryer are connected by clips 37.

The bottom section has a bottom 38.

The dryer works as follows.

Casein from above through the neck 36 of the cover 35 enters the disk 6 of the upper section and is distributed over the surface of the grille. Scraper 8, rotating slowly, flattens the casein layer on the ke, and gradually moves it from the periphery to the center. Through the neck 4 of the upper grate, the desiccated casein drops onto the disk 6 of the underlying section, where the process is repeated.

The passage is successively through all the grinders, the product falls to the bottom 38 of the lower section, and the scraper 25 passes it to the crusher 27, where it is crushed and is removed from the

dryers.

During the actual air, the air is heated in the air heater and is blown by the fan to the lower section of the dryer. Lift up, the air consistently passes through all layers of the product,

located on the lattices of the sections, and goes to the exhaust duct.
