Hawthorn drying


Hawthorn has the functions of lowering blood fat, blood pressure, strengthening heart, anti-arrhythmia, etc. It is also a good medicine for spleen appetite, digestion and stagnation, promoting blood circulation and removing blood stasis. It is full of chest spleen, sputum, blood stasis and amenorrhea. Essence has a good effect. The flavonoid vitexin in the hawthorn is a kind of anti-cancer drug, and its extract has a certain effect on inhibiting the growth, proliferation, invasion and metastasis of cancer cells in vivo.

Traditional hawthorn drying process

Hawthorn is a kind of fruit food, and the health and safety of the processing is very important. The traditional method of drying wood and fuel oil produces CO and soot in the drying process, and the heat is attached to the surface of the hawthorn. The heat is controlled by the man, and the temperature is too high. The hawthorn has high sugar content and coking in high temperature. Make the color of the hawthorn dark and black, affecting the quality. In order to save costs, it may choose to sulphur, one is to prevent insects and have a longer shelf life, and the other is to have better color for the sake, but the food or ingredients that are sulphur-smelted are negatively affected by the body.

 

Heat pump hawthorn dryer features

The heat pump hawthorn dryer is a new type of high-efficiency energy-saving drying equipment. Its working principle is based on the reverse Carnot cycle principle, using a small amount of electric energy, using the compressor to absorb a large amount of heat in the air, and passing the working medium through the expansion valve. Evaporating into a vapor state in the evaporator, and then compressing the gaseous working medium into a high-temperature, high-pressure gas through a compressor, and then entering the condenser to release heat to heat the drying medium, so that the heating is continuously performed. Compared to the electric dryer, two-thirds of the electricity is saved.

Dryfree Heat Pump Dryer adopts intelligent control of temperature and humidity during the drying process. The hot air circulation is evenly distributed in the closed mountain drying room. There is no external pollution, no need to smoke the sulfur, and the good haw color and The taste is very good, the shelf life is long, and it is more popular in the market.

Hawthorn heat pump drying process

1. After washing the hawthorn fruit, dry the moisture on the surface as soon as possible, then slice it, and remove or retain the core as needed. Now there are also special slicing machines, which are very efficient, and the thickness of the slices is even, generally around 3mm;

2, the moisture content of fresh hawthorn slices is about 80%, the target moisture content of drying is about 13%, using the Zhengxu heat pump dryer, the intelligent temperature of the drying equipment is set to the range of about 55 degrees Celsius, so that the hawthorn slices The free water contained in the large amount evaporates, and the hot air circulation system continuously delivers fresh air, and the air volume is uniformly delivered to each shelf, and the air is discharged, so that the evaporated water is discharged through the condensed water pipeline system;

3, the drying process of hawthorn tablets is relatively simple, hawthorn tablets withstand higher temperature, heat absorption is larger, you can raise the temperature to 60 degrees from the first stage, it takes 2-3 hours to complete, then rise to 65 degrees dehumidification The mountain has more water, and the drainage time of the general drain pipe will be about 16 hours, and then the consolidation phase of the tail section will take 2 hours;

4. The hawthorn slices must be cooled to room temperature after drying in the drying equipment. They should not be packed when the drying temperature is high.

Advantages of Dryfree Heat Pump Dryer

1, Convenient installation: easy installation and demolition, less floor space, can be installed indoors and outdoors;

2, high efficiency and environmental protection: heat pump dryer only consumes a small amount of electric energy, it can absorb a large amount of heat in the air, the power consumption is only 1/3-1/4 of the electric heater; the same coal, oil, gas Compared with water heaters, it can save about 75% of operating costs. 1 degree of electricity is equal to 4 degrees.

3, environmental protection and pollution-free: without any burning substances and emissions, is a sustainable and environmentally friendly product.

4. Safe and reliable operation: The whole system of the heat pump dryer does not have the dangers of flammable, explosive, poisoning and short circuit which may exist in the traditional dryer (fuel, gas or electric heating). It is an absolutely safe and reliable half. Close the drying system.

5, long service life, low maintenance costs: heat pump dryer is developed on the basis of traditional air conditioning technology, mature technology, stable and reliable performance, long service life; safe and reliable operation, fully automatic manual operation, Intelligent control.

6, comfortable and convenient, high degree of automation, intelligent: the use of self-controlled thermostat, 24 hours continuous drying operations.

7, Wide application range, not affected by climate: Heat pump dryer can be widely used in heating and drying operations in food, chemical, pharmaceutical, paper, leather, wood, agricultural and sideline products processing industries.
