具体实施方式Detailed ways

下面结合附图和实施例对本实用新型内容作进一步说明。Below in conjunction with accompanying drawing and embodiment the content of the utility model is further described.

如图1所示,腊味干燥系统包括砖砌的窑体1,窑体1的壁体中设有保温层2。窑体1的上方设有双层真空玻璃顶面3,构成太阳能干燥窑体。本实施例中,窑体1的一边设有第一大门4和第二大门5,另一边设有进风口6和排风口7。进风口6和排风口7上,分别设有排湿风门16。窑体1的中间区域划分为第一干燥区8和第二干燥区9;窑体1的两边区域划分为第一热风循环区10和第二热风循环区11。第一空气源热泵机组12设置在第二热风循环区11内靠近进风口6的位置,对应第一干燥区8;第二空气源热泵机组13也设置在第二热风循环区11内,靠近排风口7的位置,对应第二干燥区9。在第一热风循环区10、第二热风循环区11还设有高温轴流风机14,用于使窑内热风在窑体1内循环流动,既利于充分利用热风,又能使热风的热量分布均匀。作为辅助加热之用的电发热管15设置在高温轴流风机14的吹风端。As shown in FIG. 1 , the cured meat drying system includes a brick kiln body 1 , and an insulating layer 2 is arranged in the wall of the kiln body 1 . A double-layer vacuum glass top surface 3 is arranged above the kiln body 1 to form a solar drying kiln body. In this embodiment, one side of the kiln body 1 is provided with a first door 4 and a second door 5 , and the other side is provided with an air inlet 6 and an air outlet 7 . The air inlet 6 and the air outlet 7 are respectively provided with humidity exhaust dampers 16 . The middle area of the kiln body 1 is divided into a first drying area 8 and a second drying area 9 ; the areas on both sides of the kiln body 1 are divided into a first hot air circulation area 10 and a second hot air circulation area 11 . The first air source heat pump unit 12 is arranged in the second hot air circulation area 11 near the air inlet 6, corresponding to the first drying area 8; the second air source heat pump unit 13 is also arranged in the second hot air circulation area 11, close to the exhaust The position of the tuyere 7 corresponds to the second drying zone 9 . In the first hot air circulation area 10 and the second hot air circulation area 11, there are also high-temperature axial flow fans 14, which are used to circulate the hot air in the kiln in the kiln body 1, which is not only conducive to making full use of the hot air, but also can make the heat distribution of the hot air uniform. The electric heat pipe 15 used as auxiliary heating is arranged on the blowing end of the high temperature axial fan 14 .

本实施中的进风口和排风口,并没有严格的限定,仅根据窑体内热风的循环方向而定。本实施例中热风的循环方向为逆时针,则第一空气源热泵机组12所对的风口为进风口,第二空气源热泵机组13所对的风口为排风口;如果热风的循环方向为顺时针,则上述进风口和排风口的位置相反。The air inlet and air outlet in this implementation are not strictly limited, they are only determined according to the circulation direction of the hot air in the kiln body. In this embodiment, the circulation direction of the hot air is counterclockwise, the air outlet facing the first air source heat pump unit 12 is the air inlet, and the air outlet facing the second air source heat pump unit 13 is the air outlet; if the circulation direction of the hot air is Clockwise, the positions of the above-mentioned air inlet and air outlet are opposite.

除以上设备外,在窑体内还分布设置有若干温度传感器和湿度传感器。同时还设有智能干燥控制装置。如图2所示,温度传感器、湿度传感器、电发热管、高温轴流风机、排湿风门、空气源热泵机组皆连接到智能干燥控制装置,由其进行整个干燥系统的自动化控制。In addition to the above equipment, several temperature sensors and humidity sensors are distributed in the kiln body. At the same time, it also has an intelligent drying control device. As shown in Figure 2, the temperature sensor, humidity sensor, electric heating tube, high-temperature axial flow fan, humidity exhaust damper, and air source heat pump unit are all connected to the intelligent drying control device, which automatically controls the entire drying system.

本实用新型的工作过程如下:将待干燥的物料挂在第一干燥区8和第二干燥区9内。太阳光透过双层真空玻璃顶面3,使得窑体1内的温度升高。对智能干燥控制装置进行相关参数设置,以对空气源热泵机组、高温轴流风机14、排湿风门16、电发热管15进行自动控制,温度传感器和湿度传感器向智能干燥控制装置反馈窑体内部的环境数据。第一空气源热泵机组12和第二空气源热泵机组13将经由进风口6进来的室外空气加热,送至干燥区,在高温轴流风机14的作用下,热风在两个干燥区以及两个热风循环区之间循环流动对物料进行风干。干燥初期,窑体内的空气湿度会比较大,智能干燥控制装置根据窑体内热风的循环方向,控制排湿风门16的开启或关闭,使得窑内湿空气与窑外的干空气进行交换。进风口和排风口的功能在轴流风机换向时互换,从而使得室内温湿度均匀分布。由于排风的过程中,潮湿热风会经过空气源热泵机组,被空气源热泵机组吸收其热能,因而能达到节能的目的。在窑外环境温度较低时尤为明显。电发热管15在窑内温度要求比较高或外部环境温度较低时作短时间补偿使用,电发热管15产生的热风也靠高温轴流风机14使热风在热风循环区均匀流动,以起到补偿热源的作用。完成整个干燥过程后,停止干燥系统,取出产品。The working process of the utility model is as follows: the material to be dried is hung in the first drying area 8 and the second drying area 9 . Sunlight passes through the double-layer vacuum glass top surface 3, making the temperature in the kiln body 1 rise. Set the relevant parameters of the intelligent drying control device to automatically control the air source heat pump unit, high temperature axial flow fan 14, humidity exhaust damper 16, and electric heating pipe 15, and the temperature sensor and humidity sensor will feed back the inside of the kiln body to the intelligent drying control device environmental data. The first air source heat pump unit 12 and the second air source heat pump unit 13 heat the outdoor air coming in through the air inlet 6 and send it to the drying area. The circulating flow between the hot air circulation zones air-dries the materials. In the early stage of drying, the air humidity in the kiln will be relatively high. The intelligent drying control device controls the opening or closing of the humidity exhaust damper 16 according to the circulation direction of the hot air in the kiln, so that the humid air in the kiln is exchanged with the dry air outside the kiln. The functions of the air inlet and the air outlet are interchanged when the direction of the axial flow fan is reversed, so that the indoor temperature and humidity are evenly distributed. During the exhaust process, the humid hot air will pass through the air source heat pump unit and be absorbed by the air source heat pump unit, thus achieving the purpose of energy saving. Especially when the ambient temperature outside the kiln is low. The electric heating tube 15 is used for short-time compensation when the temperature requirement in the kiln is relatively high or the external environment temperature is low. The hot air generated by the electric heating tube 15 also relies on the high-temperature axial flow fan 14 to make the hot air flow evenly in the hot air circulation area to play Compensation for the effect of the heat source. After finishing the whole drying process, stop the drying system and take out the product.

空气源热泵技术利用制冷压缩机在热力循环过程中从热源中提取的热量。由于热泵的热效率高达300%-600%(同热源及供热温度有关),即热泵消耗1kW电能,用户可以得到4kW以上的热量,所以空气源热泵系统为节能型系统。与锅炉(电、燃料)供热系统相比,锅炉供热只能将95%-98%的电能或70%-95%的燃料内能转化为热量,电热管热风加热效能只有50%-70%转化为热量,供用户使用,因此使用热泵要比电锅炉加热节省3/4以上的电能,比燃料锅炉节省4/5以上的能量;无论是在运行成本还是维修保养费用上,热泵系统都能节省成本。地处亚热带的广州,空气热量大,热的时间长,使用空气源热泵更具优越性。Air source heat pump technology utilizes the heat extracted from the heat source by the refrigeration compressor during the thermodynamic cycle. Since the thermal efficiency of the heat pump is as high as 300%-600% (related to the heat source and heating temperature), that is, the heat pump consumes 1kW of electric energy, and the user can get more than 4kW of heat, so the air source heat pump system is an energy-saving system. Compared with boiler (electricity, fuel) heating system, boiler heating can only convert 95%-98% of electric energy or 70%-95% of fuel internal energy into heat, and the heating efficiency of electric heating tube hot air is only 50%-70% % is converted into heat for users to use, so the use of heat pumps saves more than 3/4 of the electric energy compared with electric boiler heating, and saves more than 4/5 of energy compared with fuel boilers; whether it is in terms of operating costs or maintenance costs, heat pump systems are Can save costs. Guangzhou is located in the subtropical zone, the heat of the air is high and the heat lasts for a long time, so it is more advantageous to use an air source heat pump.

利用可再生清洁能源太阳能、空气源热泵等多能源灵活组合供热,对腊味制品进行干燥是一项保护环境,节约常规能源,挖掘、利用好可再生清洁能源的新技术。本实用新型采用了计算机技术的智能干燥控制装置,测量精确,控制热源供应稳定,当太阳能、空气源热泵供热使窑内温度仍达不到智能干燥控制装置设定的干燥工艺基准温度时,智能干燥控制装置将自动启动电加热系统供热,使腊味制品干燥过程的能耗及经济成本降到最低。Utilizing renewable clean energy such as solar energy and air source heat pump to provide heating flexibly, drying preserved meat products is a new technology that protects the environment, saves conventional energy, and taps and utilizes renewable clean energy. The utility model adopts the intelligent drying control device of computer technology, which has precise measurement and stable heat supply control. The intelligent drying control device will automatically start the electric heating system to supply heat, so as to minimize the energy consumption and economic cost of the drying process of preserved meat products.
