Abstract

Invention m. used in drying of high-moisture, low-dispersing dispersed materials in the food industry. The purpose of the invention is to simplify the design and increase the reliability of the supershlki. For this purpose, a bearing 8 is mounted on the drive shaft 7 above the perforated bottom 2, to which the discharge device is attached to the external fixed sleeve 9. The inner enclosure of the annular drying chamber 1 is made in the form of a protective cone-shaped shell 10 with a radius of the lower base, exceeding the outer radius of the bearing. For filling with the moist material of the drying chamber, the bottom 2 is rotated one turn. To compensate for the uneven distribution of the drying agent in chamber 1, bottom 2 is rotated one more turn for 10-12 hours about 1 sludge. S & /OK

Description

eleven

The invention relates to the technique of drying high-moisture low-particulate materials, such as malt, can be used in food and other sectors of the national economy and is an improvement of the automatic dryer, W 1185037.

The purpose of the invention is to simplify the design and increase reliability.

The drawing shows schematically the described dryer.

The dryer contains an annular drying chamber 1 with a rotating perforated bottom 2 and an outer shell 3, equipped with a hopper in the form of a feeder hopper 4 and a unloading device in the form of a screw 5 enclosed in a casing 6

On the drive shaft 7 above the perforated bottom 2, a bearing 8 is mounted, to the fixed external casing 9 of which a discharge device is attached (screw 5 and casing 6) and the internal enclosure of the annular drying chamber 1 is made in the form of a protective cone-shaped shell 10 with a radius of the lower base, which is radius bearing (its outer ring 9).

Carousel dryer works as follows.

The drying chamber 1 is pre-loaded with dry material to a height equal to two diameters of the casing 6 unloading device. To fill the remaining space of the drying chamber with a wet material, the perforated bottom 2 is rotated on

one turn, while the unloading device removes part of the pre-loaded dry material. After the dryer is filled with wet material, a bulk agent is placed under the bottom 2. To compensate for uneven distribution of the drying agent in the annular chamber 1, the perforated bottom 2 is rotated one more turn for 10-12 hours. During this time, the discharge device removes the remaining pre-loaded dry material. , and the lower layer of material, having undergone heat treatment and physicochemical transformations, is a finished product and is subject to unloading. Since then, the rotary dryer begins to work in the established eryvnom mode selection of the lower layer of the dried material and simultaneously dosypki moist material on the top layer.
