Further, the existing equipment has the defect that the feeds with different humidity can not be separated and shifted in position so as to be respectively dried. In addition, the drying equipment in the prior art has the defects of unstable performance, no monitoring facility, easy electric leakage and the like.

The working principle of the device for drying fodder of the present invention is briefly described below with reference to fig. 2 to 4.

Before the drying device works, a worker can firstly set related parameters, for example, the worker can set the temperature threshold of the temperature controller to be respectively as follows through a control panel of the temperature control system: 65 degrees (steam valve opening temperature) and 70 degrees (steam valve closing temperature); the interval time of the drainage can be set to be 30 minutes through a control panel of a time relay; in addition, the parameter of the pressure reducing valve can be set to be 0.1MPa, and the parameter of the safety valve can be set to be 0.15MPa.

The worker then moves a first batch of wet feed (e.g., rice crust material) with the cart to the vicinity of the dryer and spreads it with a shovel over one third of the area of the dryer plate adjacent to the fan, i.e., the material is between the fan and the first scraper. At this time, the temperature probe detects that the temperature in the drying box is lower than 65 ℃, so the temperature controller automatically controls to open the steam valve, and the industrial steam enters the drying box through the steam valve, the pressure reducing valve and the pipeline. Further, steam stretches to whole stoving case along the passageway that the baffle encloses that the stoving incasement is enclosed, and then heats the stoving dish on stoving case upper portion, and the fan is opened simultaneously and is discharged inside damp and hot air to the realization is dried wet fodder.

As the steam entering the drying box increases gradually, the temperature and pressure inside the drying box continue to increase. When the pressure value is too high and exceeds the pressure threshold value of the pressure reducing valve, the pressure reducing valve automatically opens to discharge steam, so that the steam pressure in the drying box is reduced, and the drying box is protected. Further, in this process, if the pressure reducing valve malfunctions, the safety valve discharges gas to protect the pressure reducing valve and the drying box. Meanwhile, in the drying process, when the temperature probe detects that the temperature in the drying box exceeds 70 ℃, the temperature controller controls to close the steam valve, and at the moment, steam is prevented from entering the drying box, so that the purposes of controlling the drying temperature and protecting the drying box are achieved.

As the drying time is extended, condensed water is generated in the drying box. Since the time relay is set by the operator in advance, the time relay automatically opens the drain valve every half hour, so that the condensed water is drained. In the drying process, the staff detects the water content of the feed at random, and when the water content of the feed reaches a reusable standard (for example, the water content is about 16%), the feed can be recovered, so that the drying process of the first batch of wet feed is finished.

If in the drying process of the first batch of wet feed, the staff conveys the second batch of wet feed to be dried, when the second batch of wet feed is placed in the drying disc, the first scraper blade is firstly pushed so as to sweep the first batch of material being dried to the two-thirds area interval of the drying plate, and the second batch of wet material is paved on the drying plate close to the radiating fan and fully paved in the front one-third area of the drying plate, namely the second batch of wet material occupies the position of the original first batch of wet material. Next, the aforementioned drying operation is started for the second wet feed batch and the first wet feed batch.

When a worker conveys a third batch of wet feed to dry, the first scraper and the second scraper are pushed to clean the first batch of material and the second batch of material to the rear positions respectively, and then the fresh third batch of wet material is placed on the drying plate to be flattened close to the radiating fan and the front one third area of the drying plate is fully paved. Next, the aforementioned drying operation is started for the third wet material, the second wet material, and the first wet material. When the worker conveys a fourth batch of wet feed to dry, the first batch of wet materials are completely dried, the worker unloads the air inlet net of the air inlet, sweeps the first batch of materials out of the air inlet (the discharge outlet) by using the third scraper blade, and sweeps the rest materials to the later position respectively. Analogize with this, can realize utilizing the utility model discloses a device is dried in proper order in turn to wet fodder to production efficiency has been improved. When the drying device is stopped and is not used, the worker turns off the power supply, empties the materials on the drying disc, and simultaneously empties the interlayer accumulated water in the drying box to prevent the materials from being frozen.

Based on the above description, can understand the utility model discloses a device for drying fodder, through introducing steam and then heat the stoving dish in the stoving case to realized drying wet fodder and reached the mesh that can reuse. Further, the device has realized the automation of stoving process through setting up temperature control system to solve the easy problem that produces the thickener of fodder stoving in-process, and saved manpower resources. In addition, the device is provided with a pressure reducing system and a water draining system, so that the drying process is safe and effective, and the risk of frost cracks of drying equipment and pipelines in winter is avoided. Moreover, the device can dry the materials in different areas by skillfully designing the material conveying system, thereby realizing reasonable utilization of heat, reducing energy consumption and improving drying efficiency.

The structure and function of the device for drying fodder according to the present invention have been described above only for the purpose of example and simplicity, but depending on the different application scenarios, the device may additionally comprise other components or may also have other structures, for example for uniform heating, the trend of the internal partition of the drying box of the device may be circular or other shapes, instead of just the solution of the vertical layout mentioned above. For another example, an inclined slide way can be arranged at the edge of the drying disk of the device for facilitating the discharging. In addition, in order to enhance the sealing performance of the drying box body of the device, a sealing ring and the like can be arranged at the joint of the corresponding parts.
