Air energy high-temperature heat pump tunnel type multifunctional drying production equipment

Abstract

The invention relates to the field of drying devices, in particular to air energy high-temperature heat pump tunnel type multifunctional drying production equipment. The production equipment is provided with a rectangular hollow drying box, wherein a feeding port and a discharging port are formed in the two ends of a pipeline respectively; a conveying belt is arranged in the pipeline; a heat pump heating main machine is arranged along the conveying belt; the heat pump heating main machine is connected with a hot air exchanger through a heat supply pipeline; a cooling pipeline is connected between the heat pump heating main machine and the hot air exchanger; a fan is arranged and fixedly connected with the hot air exchanger; a moisture exhaust and air return fan is arranged above the conveying belt and connected with an air return duct; an opening of the air return duct penetrates through the outer wall of the drying box; and the outer wall of the air return duct is connected with the through position of the drying box in a closed mode. Materials are in a sealed state in the equipment, and can be continuously fed through the feeding port in the operation process of the equipment, so that the equipment can continuously work, and the problem that existing equipment can only conduct drying in batches in the working process is solved.

Description

technical field [0001] The invention relates to the field of drying devices, in particular to air-energy high-temperature heat pump tunnel-type multifunctional drying production equipment. Background technique [0002] Planted agricultural products need to be dried after harvesting. The traditional drying method is to use the sun to dry rice. This method of drying rice by the sun is becoming less and less suitable for the development of modern rural areas, because there are fewer and fewer places to dry rice. , the efficiency of drying grain is too low; for this reason, some drying equipment dedicated to drying crops have appeared on the market, but these drying equipment are either simple in structure, large in size, low in drying efficiency, uneven in drying, or drying The effect is good, but the materials can only be dried in batches, and the heat loss inside the equipment is very large every time the drying materials are replaced.

[0002] Planted agricultural products need to be dried after harvesting. The traditional drying method is to use the sun to dry rice. This method of drying rice by the sun is becoming less and less suitable for the development of modern rural areas, because there are fewer and fewer places to dry rice. , the efficiency of drying grain is too low; for this reason, there are some drying equipment specially used for drying crops on the market, but these drying equipment are either simple in structure, large in size, low in drying efficiency, uneven in drying, or drying The effect is good, but the materials can only be dried in batches, and the heat loss inside the equipment is very large every time the drying materials are replaced
