Heat pump dryer assists drying

"People to the middle age, the bubble in the vacuum flask" is a popular phrase in the Internet. The nutritional value of scorpion is very high, mainly based on dry food. Drying machinery is essential during the drying process.

The status of 枸杞 in China's health care industry can be said to be very high. It was recorded in the Book of Songs and Shan Hai Jing more than 2,000 years ago. The famous pharmacologist Li Shizhen of the Ming Dynasty also detailed in his book Compendium of Materia Medica. The medicinal value of roots, seedlings, seeds and leaves of alfalfa is recorded.

Modern people eat cockroaches, mainly using dried hazelnuts to make tea. Fresh glutinous rice is not easy to preserve after being picked, and it needs to be dried and processed in time. Heat pump drying is a hot food drying process, and it is also commonly used for drying.

The air energy dryer is one of the food machinery that uses the heat pump drying method. It is a new type of high-efficiency energy-saving dryer. The main principle is the reverse Carnot cycle, which uses air drying equipment to dry the materials. The whole process is very green and environmentally friendly. It will not produce waste residue, nor will it generate exhaust gas due to burning like the old production process, and it will also eliminate the danger of open flame.

The process of drying the concrete by the air energy dryer is mainly divided into three stages: one is the temperature rising stage, the other is the constant speed drying and tidal stage, and the third is the speed reduction setting stage.

The first stage: put the fresh glutinous rice in a flat and non-overlapping place, put it into the oven and close the door. After the equipment is turned on, the temperature inside the box will gradually rise to 50 degrees. After the moisture is generated, the moisture will start to be ventilated and the temperature will be adjusted. At about 45 degrees, this time is about 0.5 to 1.5 hours.

The second stage: At this time, the temperature should be controlled below 50 degrees, and the color change and the surface water vapor change should be paid attention to at any time, and the moisture is discharged according to the change, which is about 3 to 3.5 hours.

The third stage: At this stage, the temperature of the dryer should rise to more than 60 degrees, but not more than 70 degrees.

In addition to air energy, the heat pump drying process also includes the use of wind, solar, wind and air energy.

Compared with ordinary drying, heat pump drying has a relatively large advantage.

First: heat pump drying is safe and reliable, environmentally friendly and non-toxic. There is no open flame during the operation of the machine, and the reliability is high; it is non-toxic* and does not affect the environmental quality.

Second: heat pump drying quality and quantity. The machine is intelligently controlled during the drying process to improve product quality while ensuring production.

Third: heat pump drying saves time and effort. Mechanical setting is programmed, time is standardized, labor costs are saved, and labor intensity is reduced.

Fourth: heat pump drying is energy efficient. Compared to traditional drying, the energy consumption of heat pump drying can be reduced by more than 40%.

The application range of heat pump drying is also very wide. It is not only suitable for drying foods such as grain, fruits, vegetables, spices, algae, aquatic products, etc. Some Chinese medicine raw materials, pharmaceutical preparations and other medicines are also applicable. With the maturity of heat pump drying technology and its own technical advantages, heat pump drying will be the drying demand of most food-related enterprises in the future.
