Pepper drying room is good to pay more attention to these aspects. (1) Temperature requirements. First, the temperature range of the drying chamber: Drying chamber is 40-130 ℃ temperature range, different heating mode and different types of dry material at different levels to the influence of the temperature of drying chamber, such as using electric heating drying room temperature can reach 130 ℃, the air can heat pump heating drying room temperature can reach 80 ℃, using coal heat drying room temperature can reach 200 ℃, when the choice must pay attention to the above points, In addition, the temperature accuracy of the drying chamber should be plus or minus 5℃. The temperature in the baking room should be uniform, and the temperature should be constant throughout the room. The hot pepper drying room heats up fast, the requirement reaches the set temperature range within 1 hour. The drying chamber should be cooled quickly and should reach room temperature within 1 hour. The hot pepper drying room has good heat preservation performance. The heat preservation performance of the hot pepper drying room mainly depends on the design of the insulation layer of the drying room and the room body material […]
Chrysanthemum drying room, active temperature control, save time and labor. The principle is as follows: 1. The heating principle of the drying room: The heating mechanism of the drying house is hot. And the heat in the air is sent into the drying room by the fan. In the process of drying, the inlet is equipped with a temperature detector, and the operation of the heat pump host can be actively controlled according to the inlet temperature. When the temperature of hot air in the air inlet is lower than the set temperature (e.g., 60 degrees), the heat pump host starts to operate and add hot air supply to satisfy the dry demand of materials. Usually, the early stage is the heating time, and the late stage is the heat preservation time. When the temperature of the hot air in the air inlet reaches the set temperature (such as 70 degrees), the heat pump main engine stops operation, the lower the temperature requirement of the drying room, the longer the heat preservation time, so as to achieve the role of energy saving. 2, drying room humidity principle: Drying room humidity system, by the heat pump drying system active control. When […]
Chrysanthemum drying room is mainly used for drying machines. Also called air dryer is through heat pump, will be placed in the relatively closed insulation board room, through closed dry air circulation to condense water vapor on the cold sheet and discharge the board room, to achieve the intention of dehumidification and boring. Drying room working principle: (1) Compression process: Low temperature and low pressure refrigerant gas is compressed into high temperature and high pressure gas by the compressor. At this moment, the work done by the compressor is converted into the internal energy of the refrigerant gas, which increases the temperature and pressure, and is called an adiabatic process in thermodynamics. (2) Condensation process: The high temperature and high pressure refrigerant gas from the compressor flows through the condenser. It uses the wind or water to continuously release heat to the outside world. Condenses into medium temperature and high pressure refrigerant liquid. When the refrigerant is liquefied, the temperature drops but the pressure remains the same, which is called isobaric process in thermodynamics. (3) Saving process: The medium temperature and high pressure refrigerant liquid from the condenser becomes low temperature and low pressure refrigerant liquid by saving the equipment. […]
The food drying room has the advantages of simple structure, low energy consumption and convenient maintenance. Automatic temperature control, saving time. Good thermal efficiency meets the national zero pollution emission standard. High heat exchange efficiency, up to 95, saving 50 than electric heating. Clean hot air, no pollution. The output temperature is stable. When the food dryer is in operation, it is a high occurrence period of failure. The main failures during operation can be roughly divided into two categories: (1) Performance failure of food dryer. This type of fault is mainly caused by the performance decline, such as insufficient heating gas, high exhaust temperature, internal equipment failure phenomenon, etc. Food drying room does not run; Possible causes: Its electrical wiring is not old, the reasons vary, but may involve wiring problems. The food drying room is running and making strange noises or vibrations; Possible reasons: Due to frequent overloading or contact with foreign bodies, the lubrication of each bearing is not in place. (2) Quality failure of the food dryer itself. This kind of operation failure is caused by the quality problems of the dryer itself. For example, shaft power is too large, long time work leads to mechanical […]
What equipment does pepper drying need? The pepper drying room is an automatic drying equipment. Which is an indispensable processing equipment for small and medium-sized growers in the pepper drying process. But for users who are just starting to use this drying equipment, they may not be familiar with pepper drying. dry room. The pepper drying room is mainly composed of the drying room host, heat source equipment, trolley tray, electrical control system, blower, heat source recovery system and other system equipment. It mainly uses the principle of hot air circulation to achieve the purpose of pepper drying. The pure hot air generated is sent to the drying room, and the circulating fan in the drying room makes the hot air circulate 360 degrees in the drying room. The hot air gradually takes away the moisture of the pepper material and discharges the hot and humid air. The hot air recovery system that comes with the pepper drying room will dry it. The hot and humid air discharged from the room is dehumidified and then heated and recycled, which can not only achieve the purpose of drying peppers. But also has the effect of reducing emissions without producing pollutant emissions […]
QChrysanthemum drying room is composed of heating room and material room honeysuckle drying special equipment. The main equipment includes heating equipment, ventilation and dehumidification equipment, and temperature and humidity control equipment. The hot air in the drying box is closed, the circulation is reduced, the thermal efficiency is high, the energy is saved and there is no secondary pollution, in line with the national food hygiene standards. Chrysanthemum drying should pay attention not to spend less than 80% of the time to turn over. So as not to black the needle, quality decline. In addition, should also control the drying temperature, humidity and time, so that the drying of flowers in good shape, uniform drying, more durable storage. But we should also pay attention to the storage method, insect proof, moisture-proof, graded packaging. Chrysanthemum drying room long service life, low maintenance cost: With the traditional air conditioning operation mode is almost the same. Chrysanthemum drying room technology is mature, stable and reliable. Each part of the use of good technical materials and equipment, greatly extended the service life. Intelligent degree of chrysanthemum dryer is high. Chrysanthemum drying room has intelligent PLC control system, can control chrysanthemum drying process of time, […]
QFirst, temperature requirements 1.Drying room temperature scale; Set temperature 40-130 degrees Celsius; Temperature +-5 degrees; 2.The temperature is uniform, the temperature difference between the probe (3) does not exceed 5 degrees; Drying room needs to ensure that the temperature throughout the room is stable, (such as demand can be installed internal circulation device, like the blower oven); In addition, the room needs to be equipped with air outlet to ensure the outflow of water vapor. 3.Fast heating, requirements within 1 hour to reach the set temperature scale; 4. Fast cooling, requirements in 1 hour to reach the room temperature scale; 5.Heat preservation performance is good, no temperature shaking phenomenon. Two, humidity requirements Indoor humidity control scale:Less than 15%, and need to pay attention to how to quickly exhaust water vapor, because fresh samples put in, will immediately produce a lot of steam, need to be cleaned in time.
