Is it appropriate to choose heat pump equipment for tobacco drying?

PHNIX drying heat pump can be used in agricultural breeding, planting, industrial electroplating, wood drying, tobacco drying, food drying, etc.

The use of air source heat pump equipment for tobacco drying is more suitable, intelligent control of drying temperature, humidity and time, safety, environmental protection and energy saving, you can find Guangzhou Dingmei.

The use of drying heat pump to dry tobacco leaves, environmental protection, high quality, labor-saving, time-saving.

Tobacco leaves are very suitable for roasting with heat pump dryers, first of all, let's take a look at what are the traditional tobacco drying methods?

1. The most primitive is to use firewood; It takes a week to bake a room (drying room) tobacco leaves, during which the fire can not be stopped, and there needs to be manual continuous observation, a large amount of firewood needs to be wasted, not to mention, the temperature and humidity are not well controlled, and the drying of tobacco leaves is usually dried by experience, and the color of the dried tobacco leaves cannot be guaranteed.

2. Use coal to bake; Relative to firewood, the labor intensity of labor is about the same, and it also needs to be baked uninterrupted for about a week, and the most difficult thing to control is the temperature of the fire, which is either scorched or a little worse, and the color is very unstable.

3. Use an electric heating pipe to bake; This method is much more advanced than the first two drying methods, first of all, the temperature and humidity can be automatically controlled, and the drying time of a drying room also takes about a week, and the electricity consumption is about 1000 degrees. The labor intensity of workers has also been greatly reduced, and the only defect is that the electricity consumption is very large and does not save energy. And the remote mountainous areas do not have such a large amount of electricity power.

4. Heat pump drying; With the rapid development of science and technology, heat pump drying in the last two years has risen, first of all, heat pump drying energy saving and environmental protection, no pollution and no emission, the use of internal circulation heating, condensation and water removal method to dry tobacco leaves, temperature and humidity automatic control, can be set according to the process requirements of the relevant parameters, the unit runs automatically, greatly reducing the labor intensity and drying cost of tobacco farmers, the drying time is generally about 6 days, the electricity is about 6-700 degrees, compared with the traditional drying method to save more than one-third, And the drying color of tobacco leaves is also better. It is the most ideal tobacco drying equipment at present.

Here are a few renderings of tobacco leaves:

Dear, thank you for your patience, cold and hot roasting of tobacco leaves is the method of roasting tobacco leaves. It is the baking of tobacco leaves, which is to adjust the temperature and humidity in the roasting room, so that the chemical composition of tobacco leaves undergoes a series of changes that are conducive to improving quality, and tobacco leaves show unique color, aroma and taste, and tobacco leaf roasting is a complex physiological and biochemical process accompanied by physical changes. Among them, the physical change refers to the moisture slippage in the tobacco leaves, which is carefully and continuously vaporized and discharged from the tissues, so that the tobacco leaves gradually dry.

Hope it helps! If you are satisfied with my service, thank you for giving me a thumbs up with your precious fortune hand.

Tobacco. Heat pump dryers.

Compared with the traditional drying method, the first thing is in.

Energy consumption. To have an advantage, the tobacco heat pump dryer also belongs.

Air energy. A product of the Pei tribe is transported and collected.

Air. .

Energy. As.

Heat. The energy-saving effect is 4 times or more than that of the beam system drying method; Then there is drying control, the tobacco heat pump dryer uses intelligent control, which can draw the drying curve that is not the same as the ear, and the traditional drying method can only rely on manual control, and the experience requirements for personnel are also very high, and if you don't grasp it well, the tobacco may be bad; Finally, there is the maintenance, due to the installation of the tobacco heat pump dryer.

Drying room. Outside, moreover.

Integration. High, therefore, easy to maintain, while the traditional drying method, it is difficult to maintain. Therefore, the tobacco heat pump dryer is of course better than the traditional drying method. As far as I know, Jiuheng.

New energy. The heat pump dryer is in.

Hunan. Guangxi.

Yunnan. etc.

There are many cases of tobacco drying. You can go and study their cases.

There are several processes related to tobacco drying:

1) Compression process: The refrigerant gas at low temperature and low pressure is compressed into gas at high temperature and high pressure by the compressor. At this time, the work done by the compressor is converted into the internal energy of the refrigerant gas, which increases the temperature and pressure, which is called the adiabatic process in thermodynamics.

2) Condensation process: The high-temperature and high-pressure refrigerant gas from the compressor flows through the condenser, and the wind or water is continuously released to the outside to condense into a medium-temperature and high-pressure refrigerant liquid. Liquefaction occurs when the temperature of the refrigerant decreases but the pressure does not change, which is thermodynamically called an isobaric process.

3) Throttling process: The medium-temperature and high-pressure refrigerant liquid coming out of the condenser becomes a low-temperature and low-pressure refrigerant liquid through the throttling device. In thermodynamics, it is called the isenthalpy process.

4) Evaporation process: The low-temperature and low-pressure refrigerant liquid from the throttling device flows through the evaporator, and continuously absorbs heat into the room with wind or water, and evaporates into low-temperature and low-pressure refrigerant gas. The absorbed heat becomes the latent heat of the refrigerant, and although the temperature does not rise much, the internal energy increases a lot.

Since the pressure does not change much, it is thermodynamically called an isobaric process.

Dongbei heat pump dryer principle.

The heat pump dryer uses the reverse Carnot principle to absorb the heat of the air and transfer it to the room, so as to increase the temperature of the drying room and cooperate with the corresponding equipment to realize the drying of materials. Compared with electric dryers, two-thirds of the electricity is saved.

The refrigerant circulates through the system under the action of the compressor. It completes the gaseous pressurization and heating process in the compressor (temperature up to 115), it enters the internal machine and releases high-temperature heat to heat the air in the drying room, and at the same time it is cooled and converted into a liquid state, when it runs to the external machine, the liquid state is quickly endothermic and evaporated and converted into a gaseous state again, and the temperature drops to minus 20 - 30, then the air around the heat absorber will continuously transfer heat to the refrigerant. The refrigerant is continuously circulated to transport the heat in the air to the drying room and heat the air temperature in the room.

At the same time, it can be combined with solar energy, and the inexhaustible solar energy is more energy-saving and more environmentally friendly.

Dongbei Solar + Heat Pump Dryer:

As the latest heat pump dehumidification and drying method, it has been widely used in seafood, vegetable dehydration, melon seeds, peanuts, fruits and vegetables, meat products, casings, tobacco, leather, shiitake mushrooms, wolfberry, dried fruits, mosquito coils, tribute incense, cloth, clothing, grains, noodles, yuba, fertilizers, medicines, Chinese medicinal materials, paper products, wood, seeds and other industries. Dongbei Solar.

It can dry products such as textiles and foods that require low temperature (no more than 100 degrees Celsius).
