UA18742U - Device for grain drying on the vibrating surface - Google Patents

Abstract

A device for grain drying on the vibrating surface comprises a perforated floor of semicircular form in cross section, this is divided to working section and immovable one, a feeder, fans, a calorifer, a cyclone and vibrator. The perforated floor is attached to guiding strips for re-entry of pellets to loading zone, those form a closed line of motion of fluoroplastic pellets and of product and drying thereof.

Description

Description of the invention

The useful model refers to devices for drying beer grains and can be used for 2 processing of high-moisture waste from the brewery, sugar and other industries.

Known devices for drying high-moisture food products, including beer groats (1), containing a vibrating grid or a tray of rectangular or circular cross-section. The disadvantages of these devices are the formation of stagnant zones and large connections of dry product particles, which leads to quality deterioration and production of non-standard products. 70 A device for drying food products is also known, which consists of a perforated grid, a feeder, fans, a heater, a cyclone and a vibrator |2). The disadvantage of the known device is the need to clean the grate after some time of operation and increase the energy costs for increasing the pressure of hot air under the grate and its fluctuations.

The closest in terms of technical essence is a device for drying beer grain, which consists of 12 perforated grids, a feeder, fans, a heater, a cyclone and a vibrator |Z). The grid is made in the form of a semicircular tray with a cross-section divided lengthwise into a working vibrating section and a stationary non-vibrating section. The stationary part of the grid has two roundings (turns) in the horizontal plane, on which the resistance to the movement of fluoroplastic balls increases due to increased friction at these turns.

The main disadvantage of the described device for drying beer grain is the need to increase energy costs to increase the power of oscillations for stable movement of fluoroplastic balls.

The useful model is based on the task of expanding the technical capabilities of the device for drying beer grains by introducing a grid of guide rails into the design, which replace most of the massive perforated tray with rails made of round wire and reduce the resistance on the way to return the fluoroplastic balls to the feeder.

The task is achieved by the fact that in the device for drying beer grains on a vibrating surface, which consists of a perforated grid of a semicircular cross-section, divided into working and stationary sections, a feeder, fans, a heater, a cyclone and a vibrator, according to a useful model, a perforated the drying grid is combined with the guide rails for returning the balls to the loading area, which together form a closed line of movement of fluoroplastic balls, the product and its drying. with

The technical essence of the proposed device for drying beer grains on a vibrating surface is explained by its graphic material in Fig. 1, Fig. 2.

The device for drying beer grain on a vibrating surface consists (Fig. 1) of a perforated grid in the form of a semicircular cross-section, which is divided into working and stationary sections with guide rails c 1, fluoroplastic balls 2, feeder C, discharge fan 4, heater 5 heating air, extraction fan 6, cyclone 7 and vibrator 8. --

The operation of the device for drying beer grain on a vibrating surface is as follows. The raw shot is loaded onto the surface of the grid 1 of a semicircular cross-section, which is divided into working and stationary sections and balls 2 through the feeder 3. Under the action of the hot air flow, which is formed by the discharge fan 4 and the heater 5 and the directional 5 vibrations formed by the vibrator 8. From 50, the shot moves together with the balls 2 along the perforated grid, at the end of which the dried product c is sucked by the extraction fan 6 into the cyclone 7, and the fluoroplastic balls are returned to the loading zone c" along the guide rails, which, together with the perforated grid 1, form a closed the line of motion of these balls (Fig. 2).

Thus, the proposed device for drying beer groats on a vibrating surface has technical and economic advantages, because it allows to reduce energy costs during the operation of the dryer and material costs during the manufacture of the device by reducing the resistance on the way of the balls returning to the feeder and reducing the mass of the grid.
