[0002] In the fields of seed breeding and grain storage, accurate analysis of the free water and bound water content in grains is crucial for assessing seed vigor, processing quality, and storage stability. Traditional moisture determination methods often employ prolonged heating in a single high-temperature oven, calculating total moisture content through weight loss. This approach fails to distinguish between different forms of water, making it unsuitable for the needs of refined breeding research. The process is cumbersome and time-consuming, requiring the sample to be removed from the oven for weighing, which is susceptible to fluctuations in ambient temperature and humidity, leading to measurement errors. Furthermore, the lack of an integrated real-time weighing and temperature control system hinders automated continuous monitoring, limiting analytical efficiency and data accuracy, and preventing the provision of more in-depth moisture status information for seed physiological research.

[0003] To address these issues, we provide a grain moisture analyzer for seed breeding. Utility Model Content

[0004] The purpose of this invention is to provide a grain moisture analyzer for seed breeding. By setting a drying component on a platform scale, the drying component dries the grain at different temperatures, successively drying out the free water and bound water in the grain. The platform scale records and calculates the weight changes during the drying process, thereby obtaining the weights of the free water and bound water in the grain. By covering the drying component with a top cover, external airflow can be prevented from interfering with the detection of the platform scale when it blows over the drying component and the weighing platform.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0016] Please see Figures 1 to 3 This utility model is a grain moisture analyzer for seed breeding, including a platform scale 1, a drying component 2 and a top cover 3. The drying component 2 is set on the upper surface of the weighing platform on the platform scale 1. The platform scale 1 monitors the weight of the grain in real time. The drying component 2 dries the grain at a stepped temperature, successively drying out the free water and bound water in the grain. The platform scale 1 records and calculates the weight changes during the stepped temperature drying, thereby obtaining the weights of the free water and bound water in the grain respectively. The top cover 3 is placed above the weighing platform of the platform scale 1 on the outside. The upper end of the top cover 3 is connected to an exhaust pipe 301. By placing the top cover 3 above the drying component 2, the external airflow is prevented from interfering with the detection of the platform scale 1 when it blows over the drying component 2 and the weighing platform of the platform scale 1.

[0017] Specifically, a rubber ring 101 is fixed on the outer side of the weighing platform on the upper end face of the platform scale 1. The inner wall of the top cover 3 is in contact with the outer wall of the rubber ring 101 to increase the sealing of the top cover 3 and prevent external air from entering its interior from the bottom of the top cover 3.

[0018] Furthermore, an insulation sleeve 302 is fitted on the outer side of the upper end of the top cover 3, and the exhaust pipe 301 is fitted inside the insulation sleeve 302. When the grain is dried in the drying component 2, the moisture in the grain is evaporated into water vapor. At the same time, the temperature of the top cover 3 rises as the drying component 2 is heated. The insulation sleeve 302 keeps the temperature of the top cover 3, preventing the water vapor from condensing into water droplets after contacting the top cover 3 during the rising process and dripping back into the drying component 2, which would interfere with the detection.

[0019] The operation process of this embodiment is as follows: First, the grain is placed in the drying component 2, the platform scale 1 detects the weight, and the weight is marked as the initial weight. The temperature of the drying component 2 is set to 60 degrees to continuously dry the grain. The platform scale 1 monitors the weight change in real time and transmits the weight data to the display panel. When the data monitored by the platform scale 1 remains unchanged, the reading at this time is recorded as the weight containing bound water. The temperature of the drying component 2 is set to 105 degrees and the grain continues to be dried. The platform scale 1 continues to detect the weight. When the weight data remains unchanged, the reading is recorded as the dry weight. The initial weight is subtracted from the weight containing bound water to obtain the weight of free water in the grain. The weight containing bound water is subtracted from the dry weight to obtain the weight of bound water in the grain. Thus, the specific gravity of free water and bound water in the grain in the initial state can be analyzed. Example 2

[0020] Please see Figures 1 to 5 Based on Example 1, the drying assembly 2 includes a heat insulation pad 201, an electric heating cylinder 202, and a sample placement rack 203. The electric heating cylinder 202 is disposed on the upper surface of the heat insulation pad 201, and the sample placement rack 203 is disposed inside the electric heating cylinder 202. Grain samples are placed above the sample placement rack 203. After the electric heating cylinder 202 is powered on, it heats up and dries the grain samples in the sample placement rack 203. The heat insulation pad 201 is fixedly installed on the upper surface of the weighing platform 1 to prevent the high temperature of the electric heating cylinder 202 from being transferred to the platform 1 and burning out the sensors and other electronic components in the platform 1.

[0021] Specifically, a bottom support edge 203a is fixed to the lower edge of the sample placement rack 203. The lower end surface of the bottom support edge 203a is attached to the inner bottom surface of the electric heating drying cylinder 202. A set of heat transmission holes 203b are opened through the end surface of the sample placement rack 203. The bottom support edge 203a separates the sample placement rack 203 from the electric heating drying cylinder 202 to prevent direct contact from causing local overheating.

[0022] Furthermore, a motor bracket 102 is provided on the upper surface of the weighing platform of the platform scale 1. The motor bracket 102 covers the electric heating drying cylinder 202. A drive motor 102a is provided above the motor bracket 102. A paddle shaft 102b is fixedly sleeved at the output end of the drive motor 102a. Two turning paddles 102b-1 are fixedly arranged in a circumferential array on the lower side wall of the paddle shaft 102b. The lower end surface of the turning paddles 102b-1 is attached to the upper surface of the sample placement rack 203. When drying the grain sample, the drive motor 102a drives the paddle shaft 102b to rotate. The turning paddles 102b-1 on both sides of the paddle shaft 102b turn the grain sample on the sample placement rack 203 to make the grain sample dry evenly. During operation, the drive motor 102a is driven intermittently to avoid interference with the weighing reading of the platform scale 1 caused by the continuous operation of the drive motor 102a.

[0023] Furthermore, a positioning sleeve 203c is fixed at the center of the upper end face of the sample placement rack 203, and the propeller shaft 102b is fitted into the positioning sleeve 203c to facilitate the positioning and installation of the motor bracket 102.

[0024] The operation process in this embodiment is as follows: After placing the grain sample on the sample placement rack 203, spread the grain sample flat to prevent the grain from entering the positioning bushing 203c. Fit the paddle shaft 102b into the positioning bushing 203c, so that the motor bracket 102 is quickly positioned and installed on the upper surface of the weighing platform of the scale 1. The drive motor 102a intermittently drives the paddle shaft 102b to rotate. The turning paddles 102b-1 on both sides of the paddle shaft 102b turn the grain sample on the sample placement rack 203 to make the grain sample dry evenly. The scale 1 records the weight during the intervals when the drive motor 102a stops rotating, avoiding the recording of readings that cause interference when the drive motor 102a is rotating.
