Abstract

PURPOSE:To obtain an accurate moisture value, by crushing whole grain one at a time under pressure by rotation while receiving sorted while grain and detecting the moisture thereof. CONSTITUTION:A part of cereal supplied to a storage chamber from a cereal lifter 8 is supplied into a sorting apparatus 1 through an opening part 10, a supply port 16 and a guide plate 30 and is leaked downwardly in the vicinity of the start end part of the apparatus 1 while whole grain is downwardly leaked in the vicinity of the central part thereof by the rotation of the apparatus 1 and cereal with the immature ear is transferred to the final end part where leaked downwardly and the leaked immature ears and cereal with the immature ear are flowed down and guided by a guide 19 to be refluxed to the grain lifter 8 from a reflux port 17. The whole grain is leaked downwardly to the recessed part 22 of a cylinder 2 one at a time from an opening part 20 on the way of the flowing-down and guidance by the guide plate 19 to be held in the recessed part 22 and supplied between rolls 23 by the rotation of the cylinder 2 and crushed beyween the rolls 23 under pressure and, at the same time, the moisture thereof is detected. This detection process is repeated and, when cereal reached prescribed moisture, a drying machine is automatically stopped upon the reception of automatic control by an operation box and the crushed cereal after the completion of detection is discharged to a crushed cereal receiving box through a discharge port 27.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a grain moisture measuring device, and can be used in a dryer for drying grain, etc.

Problems to be Solved by the Invention In the moisture measuring device, which receives grains and simultaneously detects the moisture by compressing and crushing them between a pair of rolls of the moisture detecting device, grains with branch stalks are mixed into the grains to be measured. When measuring grains with a large amount of grain, a large amount of these grains with attached stalks must be crushed between the rolls to detect moisture content, which results in variations in the amount of crushed grains, making it impossible to accurately detect moisture content. Sometimes.

Means for Solving the Problems This invention is a grain supply body provided at the lower part of a sorting device (1) that receives a supply of grains and sorts them by rotation. The grain moisture measuring device is configured such that the grains are fed one by one to a moisture detecting device (3) that performs crushing and moisture detection at the lower part of the grain.

Functions and Effects of the Invention For example, when a moisture measuring device is used in a dryer for drying grains, the grains housed in the dryer are circulated within the dryer while being dried. The grains are fed into the sorting device (1) from the grain supply port, and are sorted into immature grains, fine grains, and grains with stalk attachment in this sorting device (1), and the immature grains are separated from the sorting device i (1). ), most of the fine grains leak near the center, the grains attached to the branches are transferred to the terminal end and crystallize from the terminal end, and the leaked fine grains are transferred to the lower part. Only one grain is held by the feeder, and the held grain is fed by the feeder between a pair of rolls of the moisture analyzer (3) at the bottom, and crushed between the rotating rolls to remove moisture. Detection is performed.

Only one grain of fine grains sorted by the sorting device (1) is supplied to the moisture detecting device (3) for moisture detection, so the amount of ground grain to be detected can be constant, and the amount of ground grains that are attached to the stems can be kept constant. Since grains and immature grains are not detected, accurate moisture values can be obtained.

When the dryer (4) reaches this point, the operation box (7) automatically controls the dryer (4) to stop automatically. The crushed grains that have been detected are discharged into the crushed grain receiving box (28) through the discharge port (27).

This detection process detects the moisture content of a small amount of crushed grain (only fine grains), so it is possible to clearly distinguish between abnormal values and normal values.If an abnormal value is detected, this abnormal value is electrically cut off. By doing this, accurate moisture values can be obtained.
