Abstract

PURPOSE:To detect correct moisture by reversing a grain particle crushing roll once in such a direction as delivering no grain particles at the startup of the roll to discharge crushed grain particles left. CONSTITUTION:Grain particles fed to a grain particle tank 3 from above are dried with a burner. Then, a motor 13 is reversed by a signal to turn a crushing roll 1 backward through gears 17 and 18 so that those building up thereon are delivered upward together with those flowing down while gears 21 and 22 meshed with the gear 17 rotate to turn a detection roll 12 forward in the direction of delivering crushed grain particles. After a given time, the motor rotates forward according to a signal and grain particles flowing down are delivered and crushed with the crushing roll 1. Then, they are carried out and fed onto the detection roll 12 and build up on the roll 12 with the reversion of the roll 12. The moisture of the grain particles is detected and then, the motor 13 is reversed. Thus, at the startup of the rolls 1 and 12, rotations are reversed once to discharge the crushed grain particles thereby permitting the detection of correct moisture.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a grain moisture measuring device and can be used in grain dryers and the like.

Problems to be Solved by the Invention A grain dryer that measures the moisture content of circulating grains at predetermined time intervals, displays the moisture content, and automatically stops the dryer when the specified moisture content is reached. In this method, the drying grains are crushed by a crushing roll, and the moisture content of the crushed grains is detected by a moisture detection device, but when the crushing roll starts, the drying grains are fed into the crushing roll. When the grinding roll is rotated in the direction of
Because of the high moisture content, when the moisture content of the crushed grains is detected by a moisture detection device, the moisture content is detected to be high, so when the specified moisture content is reached and the dryer automatically stops, it is overdried and the shell side and crushed grains are detected. may occur more frequently.

Means for Solving the Problem The present invention provides a pair of left and right parts that rotate in opposite directions to crush the grains while feeding them, and then feed and feed the grains to a moisture detection device that detects the moisture content of the crushed grains. Grinding roll (1)
, (1) is the structure of a grain moisture measuring device in which the grinding rolls (,1), (1) are configured to rotate in reverse in a direction in which the grains are not rolled in once when the rotation of the crushing rolls (,1) and (1) is started.

Functions and Effects of the Invention For example, when a moisture measuring device is used in a dryer for drying grains, a pair of left and right crushing rolls ( 1), (
1) is rotationally driven, and when this rotation starts, the crushing roll (
1), (1) is once rotated in the opposite direction in a direction that does not feed the grains, and the grains deposited on the upper part of the outer circumferential surface of the grinding rolls (1), (1) and the grains flowing down are separated from each other. Grinding roll (1), (
1) The outer circumferential surface of the roll is fed out to one side, and then the crushing roll (
1), (1) is rotated forward in the direction of feeding the grains, the grains flowing down are fed and pulverized, and fed to a moisture detection device, and the moisture detection device detects the moisture content of the crushed grains. However, since the pair of left and right crushing rolls (1), (1) rotate in the opposite direction in a direction that does not feed grains when the rotation starts, grains are deposited on the upper part of the outer peripheral surface of the crushing rolls (1), (1). The grains are not crushed and fed to the moisture detection device, but the grains flowing down are constantly crushed and the moisture in the crushed grains is detected, so that accurate moisture can be detected.

The dryer (2) is automatically stopped by automatic control, but the crushing rolls (1), (1) and the detection rolls (12), (
12) are interlocked to rotate in opposite directions, so that the circulating grains are necessarily crushed by the crushing rolls (1) and (1),
Since the remaining crushed grains deposited on the detection rolls (12), (12) are discharged, there is no need to detect the moisture content of the remaining crushed grains, so that the moisture content can be accurately detected. The crushed grains that have been detected are recycled and returned at the same time as the drying grains.
