SU1208438A1 - Drier for highly moist materials - Google Patents

Description

The invention relates to a drying technique and can be used in the food industry for: drying high-moisture materials, such as brewing malt.

The purpose of the invention is to improve the quality of drying.

1 shows schematically the proposed dryer j in FIG. 2, a fragment of a drying shaft with a perforated collector in FIG. 3, section A-A in FIG. 2.

The dryer contains a shaft 1, a loading device 2, a chamber 3 of the basement, along the river arranged sections 4 and 5, a discharging device 6. On the side surface of the mine 1 there are windows for installing perforated collectors 7 and 8 which are closed with protective covers 9. Chamber 3 of the basement, sections 4 and 5 are separated from each other by dampers 10, 11 and 12 with actuators moving the dampers 1.3 "Perforated manifolds 7 and 8 are movable and connected to gas ducts 14 by means of flexible inserts 15 Gate 16 is designed to regulate drying agent. The collectors 7, and 8 covers 9 are provided with individual drives 17 and 18. The covers 9 are intended to prevent clogging of the collectors 7 and 8 by sprouts or barley grains. Each manifold 7 and 8 is provided with a gastight tip 19,

Drying works as follows.

Initially, malt is fed through loading device 2 in. camera 3 pod livani. When this valve 10 is closed, the gate 16 is set to a position that prevents the exit agent

day in the atmosphere. The collectors 7 and 8 are introduced into the cavity of the shaft, and the protective covers 9 are removed from the shaft 1, the drying agent is supplied to the discharge manifolds 7 located in section 5 of the shaft 15 and sucked out through the headers 8 of the same section 5. The livani collectors 7 and 8 are derived from

section 4 of shaft 1, and the valve 10 connecting chamber 3 of the basement and section 4 is open. At the same time, the whole section of mine 1 is opened. The sub malt falls into section 4.

Thereafter, in section 4, collectors 7 and 8 are introduced with covers 9 attached to them, and then covers 9 are removed from section 4. The valve 1-0 closes. Malt drying begins in section 4. Simultaneously, malt is loaded into chamber 3 of the basement. After the malt moisture in section 4 decreases from 45-47 to 8-10%, malt is fed from section 4

in section 5. For this, the collectors 7 and 8 of section 4 are first closed with sheaths 9 and then removed from section 3, and the collectors 7 and 8 of section 5 are also removed from it. freeing the space of mine 1, the valve 11 is opened, and the malt i-guesses to section 5. Then the valve 11 is closed. The section is loaded with 15 malt and 4 malt from basement chamber 3. After this, the operation of introducing collectors 7 and B in sections 4 and 5 is repeated. After reducing the humidity of the malt in section 5 to 3-4%, dry malt is unloaded. For this from

sections 5 5 are given collectors 7 and 8, valve 12 is opened and the malt enters the discharge device 6,
