Closed type constant-temperature drying equipment

Abstract

The invention relates to the field of agriculture machinery, in particular to closed type automation constant-temperature drying equipment. The closed type constant-temperature drying equipment comprises a drying chamber and a control member chamber. A partition layer is arranged on the back portion of the drying chamber and internally provided with an inner circulation fan, an evaporator, a heater, a temperature and humidity sensor and a standby temperature sensor; the partition layer on the back portion is internally of a four-layer sealing structure; the drying chamber is internally provided with partition plates, inner circulation air channels are formed in the lower side in the drying chamber, and an air inlet channel and an air return channel which are used for dehumidifying are formed in the right side face of the drying chamber; the control member chamber is arranged on the right portion of the drying chamber and divided into three layers; a touch screen, a controller and a signboard are placed on the upper layer of the control member chamber; a dehumidifying machine is placed on the middle layer of the control member chamber; and a refrigerating unit is arranged on the lower layer of the control member chamber and comprises a refrigerating compressor, a refrigerating condenser and a condenser radiating fan. The closed type constant-temperature drying equipment has theadvantages of reasonable structure and good constant-temperature drying effect.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a closed constant temperature drying equipment. technical background [0002] Germplasm resources are the material basis for crop variety innovation. Before germplasm resource samples are stored in the warehouse, in order to avoid the loss of seed vitality and prolong the storage time, it is usually necessary to dry the samples to reduce the water content of the seeds. The commonly used methods are: natural drying and mechanical drying. [0003] The way of natural drying usually takes a long time and is highly dependent on the temperature and humidity of the environment, and usually the final seed moisture content is also high and the uniformity is poor, resulting in strong seed respiration (the respiration intensity is at a certain level). The range is proportional to the water content in the seeds), consumes the organic matter stored in the seeds, and may also...

[0003] The way of natural drying usually takes a long time and is highly dependent on the temperature and humidity of the environment, and usually the final seed moisture content is also high and the uniformity is poor, resulting in strong seed respiration (the respiration intensity is at a certain level). The range is proportional to the water content in the seed), consumes the organic matter stored in the seed, and may also mildew due to the reaction of aerobic respiration products with substances in the environment, thereby shortening the storage life of the seed

[0004] Mechanical drying generally adopts the method of high temperature drying. The advantage is that the drying speed is fast, the dependence on the temperature and humidity of the environment is small, and the final moisture content of the seeds is relatively low. Large, the protoplasmic structure of the embryogenic cells of the seeds is easily destroyed, and the cells are also prone to lose activity; at the same time, due to the high-temperature drying method, it also brings potential safety hazards
