Description

A vegetable seed drying box

technical field

The invention relates to a drying box, in particular to a vegetable seed drying box used in the field of plants.

Background technique

Seeds are the basis of agricultural production. Through seed selection and grading, unfulfilled, insect-eaten or deteriorated seeds can be eliminated, which can improve the vitality of seeds, increase the emergence rate and strong seedling rate in the field. At present, the seed processing industry mainly selects seeds according to their external dimensions, seed specific gravity, seed aerodynamic characteristics, seed color, etc. In comparison, the liquid specific gravity method can accurately act on each seed, and its accuracy far superior to mechanical methods. When the specific gravity of the seeds is greater than that of the liquid, the seeds sink, otherwise they float; then, the floating part is removed, and the seeds with different weights can be precisely separated. Taking the average specific gravity of the seeds as a reference, a liquid with a specific gravity gradient (such as water, salt water, yellow mud water, sugar water, alcohol, etc.) is prepared to continuously separate the seeds, and the seeds are divided into multiple layers according to the specific gravity gradient to achieve multi-level separation and selection.

After using the liquid specific gravity method, due to the large amount of water attached to the surface of the seeds, if they cannot be dried in time, the water content of the seeds will increase, which will cause the increase of the respiration intensity of the seeds and accelerate the deterioration process of the seeds. Therefore, the selected seeds must be dried back in time to reduce the water content of the seeds below the safe storage water.

detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1 and Figure 2, the present invention provides a vegetable seed drying box, which includes a support frame 1, a drying drum bracket 2, a drying drum 3, a rolling shaft 4, a motor 5, an electric heater 6, and a fan 7 , controller, airtight door 8, tide outlet 9 and monitoring device. The drying box is divided into two parts: the drying box 10 on the upper part and the instrument box 11 on the lower part through the supporting frame 1. The drying drum bracket 2 is fixedly arranged on the upper part of the supporting frame 1, and the drying drum 3 is arranged above the drying drum bracket 2. Both ends of the drying drum 3 are connected with the rolling shaft 4, which is used to rotate the drying drum 3 to ensure the uniformity of heating during the drying process. The rolling shaft 4 is arranged on the drying drum bracket 2, and one end of the rolling shaft 4 is connected to the The motor 5 is connected, and the motor 5 is fixedly arranged on the lower part of the support frame 1. An electric heater 6 is arranged directly under the drying drum 3, and a fan 7 is arranged on the lower part of the electric heater 6, which is used to make the hot air generated by the electric heater 6 enter the drying drum. 3 Around, dry the seeds. Both the motor 5 and the fan 7 are electrically connected to the controller for controlling the working states of the motor 5 and the fan 7 . One side of the drying box 10 is provided with an airtight door 8 , and the upper part of the other side of the drying box 10 is provided with a tide outlet 9 , and a monitoring device is arranged at the tide outlet 9 for monitoring the temperature and humidity of the tide outlet 9 .
