Abstract

This invention relates to devices for producing expanded grains, such as maize. The essence of the invention is as follows. The device contains a working chamber with vibratory flows and heating elements, a loading hopper located above the working chamber, and a discharge drum under the bunker. The discharge drum is equipped with an impeller fixed on its shaft. On the same shaft, behind the drum, an asterisk is fixed, having a number of rays equal to the number of blades of the impeller. A stop for interaction with an asterisk is mounted on the working chamber during rotation of the bunker, kinematically connected with vibrating channels, for which the discharge drum is fixed on the bunker with displacement relative to its vertical axis. This design provides a guaranteed discrete flow of grain into the working chamber. 3 il.

Description

This invention relates to a heat treatment technique and can be used in the food and other industries for the production of blasted grains, for example, corn.

A device for blasting corn, made in the form of a cylinder, the middle part of which is filled with a portion of grains, the volume (quantity) and the loading period of which is determined by the operator by eye, is known.

A device for blasting corn is also known, in which the movement of grains for preliminary drying and warming up is carried out by perforated trays of vibratory action.

However, this solution also lacks a uniform supply of grains, i.e. they come in an uneven continuous flow. With such a feed, the grains are heated unevenly both throughout the flow and for each kernel, and, therefore, the required quality of grain treatment is not ensured.

The purpose of the invention is to improve the quality of grain processing by means of guaranteed discrete feeding into the working chamber by fixing an asterisk with a number of rays equal to the number of impeller blades interacting with a fixed stop mounted on the working chamber lid on the shaft of the discharge drum, and the discharge drum is displaced relative to the vertical axis the supporting wheels of the bunker, and the rotation of the latter is provided by a kinematic coupling with a screen drive.

FIG. 1 shows the device; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view of D in FIG. 1. The device contains a working XI

measure 1, drive 2, loading hopper 3, support wheels 4, discharge drum 5, radial sprocket 6, fixed stop 7, receiving part 8 of the grain lines, grain lines 9, working chamber cover 10, impeller 11, drum shaft 12, heating elements 13, screen 14, eccentric 15. v The device operates as follows.

When a certain temperature is reached, which is achieved with the help of ТЭ-13, located along the contour of the working chamber, the drive 2 is turned on, transmitting the rotation to the vertical shaft with eccentric 15 and loading hopper 3. The eccentric 15 fixed on the drive shaft 2 provides reciprocating movement of the screen 14, located inside the working chamber 1 and pivotally attached to the cover 10.

From the hopper 3, the grains enter the discharge drum 5 by gravity. As the bunker 3 rotates, the asterisk 6, interacting with one of the beams with the fixed support 7, turns the impeller 11 on one sector and the grains in the section closest to the discharge opening spill into the receiving part 8 grain lines 9 and last are fed to the grooves of the screen, along which they warm up

are blessed. The support wheels 4, located along the contour of the hopper 3, ensure smooth, without slippage, rotation of the latter, and contribute to a uniform flow of grains.

The annual economic effect from the use of a plant for blowing grains will be approximately 10,000 rubles.
